Abstract: A multi-pass UV inkjet printer for outputting high glossy varnish and a printing method using the same includes providing a side UV light irradiation device at a side of an inkjet module and a front UV light irradiation device in front of the inkjet module not overlapped by a varnish print head. During output of the varnish, varnish outputted on a substrate in the nth pass is passed under the side UV light irradiation device with a lower UV irradiation power during or after the n+1th pass performed by the UV inkjet printer for shaping or temporarily not curing, and then during or after the next pass, the varnish is passed under the front UV light irradiation device with a higher UV irradiation power for complete curing, thereby increasing production yield.

Abstract: A digital inkjet flatbed printer having a separate laser processing machine includes a laser processing machine and a digital inkjet printer. The laser processing machine is provided with a laser output module and a laser processing platform. The digital inkjet printer includes an inkjet output module and an inkjet operating platform. The inkjet operating platform is capable of movably ascending from and descending onto the digital inkjet printer. Thus, when the inkjet operating platform is descended, the laser processing machine is movably connected to the inkjet operating platform, such that the laser output module of the laser processing machine and the inkjet output module of the digital inkjet printer are on the laser processing platform of the laser processing machine and sequentially used for laser processing and inkjet printing respectively.

Abstract: A composite processing machine for detectiing material height and collision comprises a machine body, a contact detection unit, a non-contact detection unit, a control module, and a judgment module. The machine body is provided with an elevating working platform. An object to be processed is placed on the elevating working platform for laser processing operation. The contact detection unit and the non-contact detection unit are movably and displaceably disposed on the machine body. The control module is connected to the contact detection unit and the non-contact detection unit respectively. The judgment module determines the object's external property in order to drive the control module to control the contact detection unit and the non-contact detection unit respectively or sequentially to detect the object.

Abstract: A printer inkjet head cleaning system for waste ink collection and inkjet head cleaning and protection comprises a frame, a pushing device and a cleaning device. An accommodating space is disposed inside the frame. A horizontal rail and an elevating rail are correspondingly disposed on two lateral sides of the frame respectively. A cover used for protecting an inkjet head is disposed on the pushing device. Two sides of the pushing device are movably coupled on the horizontal rails so that the pushing device can displace on the horizontal rails horizontally. A scraper is disposed on the cleaning device. Two sides of the cleaning device are movably coupled on the elevating rails. An end of the cleaning device is connected with the pushing device so that the cleaning device can displace on the elevating rails when the pushing device moves forward and backward.

Abstract: A fastener comprises a fixing frame, a sliding base as well as a sliding frame and a swinging arm disposed inside the sliding base. A beveled guide surface of a fastening hook of a fastening rod of the fixing frame is pressed against a front side wall of the sliding base for inserting the fastening hook into a fastening groove in order that the sliding frame is fixed by the fastening rod at a fastening position. When the sliding base moves along a detaching direction from the fastening position, a turning portion of the swinging arm can be turned by pressing against an actuating rod, and a pressing portion of the swinging arm is driven by the turning portion to push the fastening rod upward for unfastening the sliding frame.
