Paper towel and separation device of the paper
A separation device of a paper towel includes a housing provided with two roll sets each having at least two rolls that may be driven by a power member to rotate relative to each other at an equal speed, so that a continuous paper towel may pass between the rolls of the two roll sets and may be pulled downward. The paper towel is provided with sensing marks at a predetermined length, so that when the sensing mark of the paper towel passes through a detection member, the detection member may detect passage of the sensing mark of the paper towel, and may send a signal, so that a rotation speed difference is produced between the rolls of the two roll sets, and the paper towel passing between the rolls of the two roll sets may be torn off.

1. Field of the Invention
The present invention relates to a paper towel and a separation device of the paper towel, and more particularly to a separation device having a simpler construction, so that the paper towel may be separated easily.
2. Description of the Related Art
A conventional cutting structure of a paper towel in accordance with the prior art shown in
However, the blade 95 of the blade wheel 94 contacts the chopping board 06 frequently, so that the blade 95 of the blade wheel 94 is easily worn out during long-term utilization, and the cutting effect is greatly affected, thereby causing a large load in maintenance, and causing inconvenience to the user. In addition, the conventional cutting structure of a paper towel has a complicated construction.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a separation device of a paper towel, wherein the separation device has a simpler construction, so that the separation device may be manufactured easily, and the paper towel may be separated easily.
Another objective of the present invention is to provide a separation device of a paper towel, wherein the separation device of a paper towel needs not to provide a cutting blade set, thereby simplifying the construction, and facilitating production and assembly. In addition, the separation device of a paper towel does not have the problem of wear of the cutting blade, thereby facilitating maintenance.
A further objective of the present invention is to provide a separation device of a paper towel, wherein the paper towel may be separated easily at a predetermined length.
In accordance with the present invention, there is provided a separation device of a paper towel including a housing provided with two roll sets each having at least two rolls that may be driven by a power member to rotate relative to each other at an equal speed, so that a continuous paper towel may pass between the rolls of the two roll sets and may be pulled downward. The paper towel is provided with sensing marks at a predetermined length, so that when the sensing mark of the paper towel passes through a detection member, the detection member may detect passage of the sensing mark of the paper towel, and may send a signal, so that a rotation speed difference is produced between the rolls of the two roll sets, and the paper towel passing between the rolls of the two roll sets may be torn off. In addition, the roll faces of the multiple rolls provided by one of the two roll sets may form a non-single line, and the easily detachable line of the paper towel is formed by holes of different lengths.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to the drawings and initially to
The separation device comprises a housing 3, a first roll set 1, and a second roll set 2. The paper towel 4 may pass through the first roll set 1 and the second roll set 2 respectively.
The housing 3 may construct the housing wall of the entire separation device, and has at least two wall plates 31 between which the first roll set 1 and the second roll set 2 are pivotally mounted. The housing 3 is provided with a detection member 32 that may be a conventional light control detection member. When the sensing mark 42 of the paper towel 4 passes through the detection member 32, the detection member 32 may detect passage of the sensing mark 42 of the paper towel 4, and may send a signal, so that the paper towel 4 may enter the first roll set 1 and the second roll set 2 easily. A guide board 33 is mounted between the two wall plates 31, and is located above the first roll set 1 and the second roll set 2. The housing 3 may be provided with a conventional liquid spray tube 34 to wet the passing paper towel 4, and a guide plate 35 to guide the paper towel 4 outward.
The first roll set 1 consists of at least two rolls 11 and 12 each having two ends respectively pivoted on the wall plates 31. The roll faces of the two rolls 11 and 12 contact with each other or almost contact with each other. The two rolls 11 and 12 of the first roll set 1 may be rotated relative to each other by driving of drive members 13, such as gears, so that the paper towel 4 may pass between the two rolls 11 and 12, and may be pulled downward to the second roll set 2. The two rolls 11 and 12 of the first roll set 1 may be driven to rotate by a power member 14.
The second roll set 2 is located at the lower side or the rear side of the first roll set 1, and consists of at least two rolls 21 and 22 each having two ends respectively pivoted on the wall plates 31. The roll faces of the two rolls 21 and 22 contact with each other or almost contact with each other. The two rolls 21 and 22 of the second roll set 2 may be rotated relative to each other by driving of drive members 23, such as gears, so that the paper towel 4 may pass between the two rolls 21 and 22, and may be pulled downward. The two rolls 21 and 22 of the second roll set 2 may be driven to rotate by a power member 24.

The housing 3 is provided with a clutch wheel 36 whose movement may be controlled by a controller 37 such as an electromagnetic valve. When the sensing mark 42 of the paper towel 4 passes through the detection member 32, the detection member 32 may detect passage of the sensing mark 42 of the paper towel 4, and may send a signal, so that the clutch wheel 36 may detach from the drive members 13 and 23 of the first roll set 1 and the second roll set 2, and may mesh with the drive members 13 and 23 of the first roll set I and the second roll set 2 again after a predetermined period of time.
The first roll set 1 is not provided with a power member, while the second roll set 2 has a power member 24. Thus, when the clutch wheel 36 meshes with the drive members 13 arid 23 of the first roll set 1 and the second roll set 2 as shown in

The first roll set 1 consists of at least two rolls 11 and 12. The roll faces of the two rolls 11 and 12 of the first roll set 1 contact with each other or almost contact with each other. The two rolls 11 and 12 of the first roll set 1 may be rotated relative to each other by driving of drive members, such as gears, so that the paper towel 4 may pass between the two rolls 11 and 12, and may be pulled downward to the second roll set 2.

Accordingly, the separation device of a paper towel in accordance with the present invention needs not to provide a cutting blade set, thereby simplifying the construction, and facilitating production and assembly. In addition, the separation device of a paper towel in accordance with the present invention does not have the problem of wear of the cutting blade, thereby facilitating maintenance. Further, the supply length of the paper towel may be set during fabrication. In comparison, in the conventional separation device of a paper towel, the tooth number of the gear and the rotation speed of the motor need to be changed when the supply length of the paper towel needs to be changed. Further, the roll faces of the two rolls of the second roll set only have smaller contact faces, and the contacting faces of the two rolls of the second roll set are aligned with the elongated hole of the paper towel, so that the paper towel between the first roll set and the second roll set may be torn out easily, and the motor for driving the first roll set and the second roll set may provide a smaller drive torque to tear the paper towel between the first roll set and the second roll set, thereby reducing loss of power.
Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
