Description

TECHNICAL FIELD

The present invention relates to an integrated mold-pressing pillowcase and a mold-pressing forming device, belonging to the technical field of pillowcase mold-pressing forming.

BACKGROUND

It is generally believed that pillows, as a sleeping tool, are fillers used for people to sleep comfortably. From the perspective of modern medical research, a spine of a human body is a straight line from the front, but a curve with four physiological bends from the side. In order to protect the normal physiological bends of a neck and maintain the normal physiological activities of people during sleep, the pillows must be used during the sleep.

Traditional pillows generally use pillowcases with built-in filling cotton, buckwheat and the like. With the improvement of people's living standards and the development of materials, more and more pillows use mold-pressing forming pillow inners such as latex and bionic cotton. This type of the pillow inners has a fixed shape to meet the requirements of specific concave-convex functional areas, and the concave-convex surface may adapt to a physiological curve of a human body, so that sleep is more comfortable. In order to protect the pillow inner, it is generally wrapped and protected by the pillowcase, and the pillow cleanliness is maintained by replacing the pillowcase.

The traditional pillowcase adopts a cover body or a bag body to cover or wrap and protect the pillow inner, so that the pillow inner may be kept clean, and the contact surface may be cleaned by the replacement of the pillowcase, the breeding of mites and other conditions are effectively prevented, and it is safer and more comfortable to use.

However, as the people have the higher and higher requirements for sleep quality and comfort level of the pillowcase, the stability of the coordination between the pillowcase and the pillow inner is poor relatively at present, and the relative displacement between the pillowcase and the pillow inner is easy to occur during use, which affects the use. In addition, the higher requirements are put forward for the elasticity and contact comfort of the pillowcase itself.

Polyester fibers are a material with excellent elasticity, and it is a pillowcase material with very excellent plasticity. By its mold-pressing shaping, forming of various shapes may be achieved, and the requirements of mold-pressing forming as the pillow surface of the pillowcase are met. As the pillow surface, it may provide the better elasticity and contact comfort. At the same time, it may make the pillowcase have a certain tension, the fixation of the pillow inner is more reliable, and it is not easy to produce the relative movement of the pillow inner in the pillowcase.

At present, there are many existing technologies to form the pillow surface by mold-pressing polyester fabric. On Mar. 23, 2022, our company, Tengfei Technology Co., Ltd. submitted an utility model patent with an application number of 2022206406038 to the China National Intellectual Property Administration, which discloses a mold-pressing forming pillowcase, and it uses a thermal mold-pressing forming mode to achieve forming of a pillowcase top layer, and forms a complete pillowcase structure by coordinating with a fixed body.

Generally, the pillowcase includes a pillow surface, a pillowcase periphery, and a pillowcase bottom surface. Traditional mold-pressing may only achieve the mold-pressing forming of the pillow surface. Therefore, connection forming between the pillowcase, the pillowcase periphery and the pillowcase bottom surface needs to be performed. Generally, adhesive bonding, quilting, thermal compounding and other modes are used, so that the forming cost is high relatively, and the relative combination stability is poor relatively. However, in the utility model patent of 2022206406038 submitted by our company, the mold-pressing is used to achieve integrated forming of the pillowcase and the pillowcase periphery, but it also needs to be connected with the pillowcase bottom surface, and also requires a plurality of steps, so that the production cost of the pillowcase is high relatively. In addition, while the connection forming is performed, it may lead to the poorer degree of product uniformity, and long-term use is easy to cause slotting and other phenomena.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make purposes, technical schemes and advantages of embodiments of the present invention clearer, the technical schemes in the embodiments of the present invention are clearly and completely described in combination with the drawings in the embodiments of the present invention. Apparently, the embodiments described are a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to a scope of protection of the present invention.

The present application is further described in detail in combination with the drawings and embodiments. It may be understood that the specific embodiments described here are only used to explain the relevant invention, not to limit the present invention. It should also be noted that, for the convenience of description, only parts related to the relevant invention are shown in the drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflicting.

The present invention provides an integrated mold-pressing pillowcase, as shown in FIGS. 1, 2 and 4, including a pillowcase top layer 1, a pillowcase bottom layer 2 and a pillowcase peripheral wall 3, herein the pillowcase peripheral wall 3 is arranged between the pillowcase top layer 1 and the pillowcase bottom layer 2, and the pillowcase bottom layer 2 is provided with a window position 4 for carrying a pillow inner.

Specifically, the built-in pillow inner of the traditional pillowcase has the larger mobility, which affects the comfort of use. In order to meet the built-in stability of the pillow inner, a design of elastic binding or elastic sleeve body is generally adopted, while polyester fabric has the stronger elasticity and plasticity, so it is more suitable for use as a pillowcase material.

However, the pillowcase includes the pillowcase top layer, the pillowcase bottom layer and the pillowcase peripheral wall. At present, the polyester fabric may only achieve mold-pressing forming of the pillowcase top layer or the pillowcase top layer and the pillowcase peripheral wall. While the pillowcase is finally assembled and formed, the bonding or quilting between a mold-pressing forming body and the pillowcase bottom layer needs to be performed, and the secondary process coordination production efficiency is low relatively, In addition, the outer edge of the mold-formed pillowcase top layer or pillowcase peripheral wall has the characteristics of easy deformation. In the process of connecting with the pillowcase bottom layer, it may cause the poorer degree of product uniformity and affect the product qualification rate.

In the present invention, an integrated design of integrated mold-pressing forming by the polyester fabric is adopted, namely the pillowcase top layer 1, the pillowcase bottom layer 2 and the pillowcase peripheral wall 3 are integrally mold-formed by the polyester fabric, thus only the window position is reserved, so there is no need for secondary processing and production of the pillowcase bottom layer 2, which shortens the product production cycle, and improves the product forming uniformity degree, and the product qualification rate is high relatively.

It should be noted that after integrated mold-pressing forming, only the window position needs to be trimmed to meet the forming requirements. Certainly, in order to ensure the firmness of the window position and the built-in stability of the pillow inner, a button, a zipper, a magic tape and the like may be designed on the window position to meet the built-in locking stability of the pillow inner, while the overall mold-forming polyester fabric may also retain the more excellent air permeability.

In a specific embodiment, the window position 4 is a linear slotting arranged on the pillowcase bottom layer.

The window position 4 is used for demolding the mold-formed pillowcase, while meeting the in-and-out operation requirements of the pillow inner. The linear slotting design is more convenient for manufacturing of the mold-pressing production device, and also easy for the later zipper carrying requirements.

Certainly, the window position 4 may also adopt designs such as round hollow, rectangular hollow, and S-shaped slotting, and the window position design that meets the requirements of demolding and pillow inner access is within the scope of protection of the present invention.

In a specific embodiment, the pillowcase top layer 1 and the pillowcase bottom layer 2 have heat-curing positioning corner ends 5.

Specifically, the pillow inner is generally a rectangular structure body, while the pillowcase itself has the relatively uniform elasticity. It is designed by the heat-curing positioning corner ends 5, namely during the mold-pressing forming, the heat-curing positioning corner end 5 with the higher hardness is formed at the corner end by the differential temperature, thereby the stable limit of the built-in pillow inner is achieved, and the relative mobility of the built-in pillow inner is greatly reduced.

It should be noted that the polyester fabric has the higher elastic opening degree and elastic recovery. The design of the heat-curing positioning corner end 5 is adopted to meet the requirements of smooth demolding, this type of the polyester fabric with the high elastic opening degree and elastic recovery belongs to existing technologies, and its compositions and material characteristics are not repeatedly described here.

In a specific embodiment, the pillowcase top layer 1 is provided with a physiological profiling concave-convex coordination structure 6 which is coordinated with the pillow inner.

Specifically, there are many pillow inners with physiological functions at present, namely the pillow inner with a neck support, a massage bump and other designs. For this type of the pillow inners, the pillowcase adopts the design of the physiological profiling concave-convex coordination structure 6 to meet the requirements of the profiling built-in coordination with the pillow inner, it may not affect the original functions of the pillow inner, and the built-in pillow inner is also more stable and reliable, and more accurate in positioning.

As shown in FIG. 3, it is a mold-pressing forming device for forming the integrated mold-pressing pillowcase of the present invention, it includes a pillowcase mold base 20 and a heat-setting pillow inner mold 30, the pillowcase mold base 20 has a model cavity slot 10, the heat-setting pillow inner mold 30 may be moved relative to the pillowcase mold base 20, the heat-setting pillow inner mold 30 is coordinated with the model cavity slot 10, the heat-setting pillow inner mold 30 is provided with a pillow inner mold connector 40 for matching with the window position 4.

The pillowcase mold base 20 is provided with a bottom layer horizontal-push mold set 50 for forming the pillowcase bottom layer 2.

A polyester fabric loading mechanism 60 for loading the polyester fabric is arranged between the bottom layer horizontal-push mold set 50 and the heat-setting pillow inner mold 30.

Specific implementation process and principle description are as follows.

Firstly, the polyester fabric is clamped on the polyester fabric loading mechanism 60, and the heat-setting pillow inner mold 30 is pressed downwards so that the polyester fabric is stretched and pressed into the model cavity slot 10 of the pillowcase mold base 20.

While the heat-setting pillow inner mold 30 is pressed in place, the bottom layer horizontal-push mold set 50 closes a mold so that the peripheral polyester fabric is tightened and folded, and it is coordinated with the pillow inner mold connector 40 to form the pillowcase bottom layer 2 with the window position 4.

Heat-setting is performed for a certain period of time, and after the heat-setting is completed, sequential reset of the bottom layer horizontal-push mold set 50, the heat-setting pillow inner mold 30, and the polyester fabric loading mechanism 60 is performed. At this time, a mold-pressing product formed is as shown in FIG. 4. After it is removed from the heat-setting pillow inner mold 30, the integrated mold-pressing pillowcase may be obtained by trimming.

In a specific embodiment, the bottom layer horizontal-push mold set 50 includes two horizontal-push modules 500 with horizontal relative opening and closing displacement.

Specifically, the polyester fabric is in a tightening state while flanging, so two horizontal-push modules 500 may be used to meet the flatness requirements of the pillowcase bottom layer 2. Certainly, four radially coordinated horizontal-push modules 500 may also be used, and it is only met that the mechanism design of the pillowcase bottom layer 2 flanged in a flat state after being coordinated with the pillow inner mold connector 40 is within the scope of protection of the present invention.

In a specific embodiment, the polyester fabric loading mechanism 60 includes a fixed bottom support material frame 61 and a clamping locking material frame 62 with displacement towards the fixed bottom support material frame.

Namely, the polyester fabric is clamped between the fixed bottom support material frame 61 and the clamping locking material frame 62, and in the operation process of the heat-setting pillow inner mold 30 and the bottom layer horizontal-push mold set 50, it may keep the peripheral tightening state of the polyester fabric.

It should be noted that this embodiment may be optimized. There is a polyester fabric supply line for supply of the polyester fabric, and the polyester fabric supply line passes through a seam between the fixed bottom support material frame 61 and the clamping locking material frame 62, as to meet the continuous material supply requirements, so that the production efficiency is greatly improved.

Certainly, while this design is adopted, it is necessary to design a design for cutting and stripping of a formed product in the polyester fabric loading mechanism 60, it may be a circular cutting station for the window position, or a cutting station for a flanging tail material.

In a specific embodiment, the pillowcase top layer and the pillowcase bottom layer have heat-curing positioning corner ends, and the heat-setting pillow inner mold is provided with a corner end heat-curing portion 31 arranged corresponding to the heat-curing positioning corner ends. The pillowcase top layer 1 is provided with a physiological profiling concave-convex coordination structure 6 which is coordinated with the pillow inner, and the heat-setting pillow inner mold is provided with a concave-convex model portion 300 for forming the physiological profiling concave-convex coordination structure 6.

Specifically, the concave-convex model portion 300 may be used to profile with the pillow inner, while the corner end heat-curing portion 31 adopts a design that is different from the temperatures of other portions, as to meet the requirements for a certain increase in hardness of geothermal hardening at the heat-curing positioning corner end. The principle of shaping and even changing the hardness of the polyester fabric by the different heating temperatures belongs to the existing technologies, it is not repeatedly described here, and it is only necessary to set a required temperature according to the characteristics of the polyester fabric.

From the above descriptions, it may be found that a pillowcase design of integrated mold-pressing forming by the polyester fabric is adopted, the production process of the pillowcase is greatly simplified, the demand for the built-in stability of the pillow inner is met, and it has the characteristics of good air permeability, comfortable contact and the like. The requirements of built-in corner end limit and profiling coordination are met, the functions of the pillow inner may not be affected, and the built-in position of the pillow inner is accurate and reliable. The one-time mold-pressing forming requirements of the pillowcase are met by the mold-pressing forming device, it is easy to streamlined production, the degree of product forming uniformity is higher, the labor cost is greatly reduced, and the product qualification rate is greatly improved.

So far, the technical schemes of the present invention are described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the scope of protection of the present invention is apparently not limited to these specific embodiments.
