Description

Cylindrical struts with quick release function

The invention relates to the quick release structure of the printing machine drum, in particular to the cylindrical top with quick release function by using the angular displacement of the switching disc to achieve quick disassembly/assembly and matching the inner diameter of the printing machine material reel. Support structure.

In general, the printing machine uses a plurality of rollers to drive the conveyance of the printed matter, and is printed on the ink through the printing cylinder with the ink, and then conveyed to the printing machine by the roller.

Taking the printing of the plastic mold on the bottle of Baote as an example, the printed matter of the bag is painted in a uniform shape before printing, and the film is rolled into a cylindrical shape by a roller to facilitate continuous printing to improve efficiency. The roller is fixed on the feeding and unloading seat of the printing machine by using a top supporting structure on the left and right sides. Since the roller plus the plastic mold to be printed is rather heavy, the top is prevented from falling out. The support structure is fixed, although it can prevent the drum from falling out, but when the drum needs to be repaired, updated or changed specifications, it is very difficult to disassemble the top support structure one by one. When the repair is completed, it is necessary to reinstall or update the device. It is very cumbersome and difficult to remove the top support structure and lock it one by one. It requires professional technicians to start processing. Otherwise, the quality of the printing will not be controlled.

How to make the printing roller can be disassembled and assembled quickly and easily without the need of professional technicians when it needs to be repaired or updated. This is a big issue.
