Description

Technical Field

[0001] The utility model relates to the technical field of adjustable paper cutting, and more specifically, it relates to a new type of adjustable paper cutting mechanism. Background Technique

[0002] In the existing technology, the paper cutting mechanism is an indispensable device in the printing and packaging industries. It is responsible for cutting large-format paper into the required sizes. However, these mechanisms have certain limitations in practicality. Specifically, in the existing paper cutting mechanisms, the cutting disks are usually fixedly installed. This means that when adjusting the paper size, relatively cumbersome methods need to be used, which undoubtedly reduces the convenience of adjustment.

[0003] This design of fixedly installed cutting disks results in that in actual operation, technicians often need to spend more time and effort on adjustment. Every time the paper size is changed or the cutting position is adjusted, the cutting disks need to be manually disassembled or adjusted. This is not only time-consuming and laborious, but also may accelerate the wear of the cutting disks due to frequent disassembly and assembly, reducing the service life of the equipment. In addition, this adjustment method may also increase the risk of operation errors, affecting the cutting quality and efficiency, and thus affecting the smoothness of the entire production process. Content of the Utility Model
