Description

Technical Field

[0001] The utility model relates to the technical field of printing processing, in particular to a puncher of a photoelectric positioning punching machine. Background Art

[0002] PS plate, also known as pre-coated photosensitive plate, has the characteristics of high resolution, full dot reproduction, rich layers, easy to master ink balance, high printing durability, etc. It is a commonly used office tool for printing and one of the best printing materials today. Nowadays, PS plate has been mass-produced and used as a commodity for printing factories. When making plates, the operator needs to engrave on the PS plate. If the positions of the images and texts engraved on different PS plates are to be kept consistent, positioning holes need to be punched on the side of the PS plate. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: when using the puncher in the related technology to punch holes, the contact surface between the PS plate and the puncher is small, and the local stress generated during punching is large, which can easily cause the side of the PS plate to deform, affecting the punching quality, easily generating waste, and low yield rate.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN213197867U in the prior art discloses a high-efficiency puncher for a photoelectric positioning punching machine, wherein the puncher includes a punching tube, a buffer column, a buffer member and a driving assembly for driving the punching tube to vertically reciprocate, wherein the punching tube faces the workbench, one end of the buffer column slides into the punching tube, and the other end of the buffer column extends out of the punching tube and faces the workbench, the buffer member is built into the punching tube, and the buffer member is connected to the buffer column.

[0004] Although the above-mentioned prior art solution reduces local stress and waste generation when punching, the arc-shaped blade will wear out after being used for a period of time, and the staff needs to replace the new arc-shaped blade in time. The arc-shaped blade is installed on one end of the punching tube by screws. When disassembling and assembling, the staff needs to twist each set of screws one by one, which is cumbersome to operate, increases the workload of the staff, and affects the efficiency of disassembly and replacement.
