Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding devices, and more specifically, it relates to a paper feeding device for a die-cutting machine. Background Technique

[0002] A paper feeding device for a die-cutting machine is an important part of the die-cutting machine, which is responsible for accurately conveying paper or other materials to the processing area of the die-cutting machine.

[0003] In the existing technology, firstly, some devices cannot achieve continuous paper feeding, which affects the production efficiency of the die-cutting machine. It may cause the paper to shift or wrinkle during the feeding process, affecting the die-cutting quality. There is a lack of a reciprocating rotary paper feeding mechanism, making it difficult for operators to adjust the paper feeding speed and direction according to production requirements, reducing the operation flexibility. Secondly, the rotation of the turntable on the bottom plate of some devices may be unstable, affecting the accurate paper feeding. The guiding property of the rotary support mechanism decreases, which may lead to position deviation of the paper during the feeding process. Without stable rotary support, long-term operation may cause increased equipment wear and shorten the service life of the equipment. Finally, the positioning and fixing of the paper during the paper feeding process of some devices will be affected, which may lead to inaccurate die-cutting positions. The paper may wrinkle during the feeding process, affecting the die-cutting quality. The flatness and stability of the paper cannot be guaranteed, thus affecting the paper feeding quality and die-cutting effect. Content of the Utility Model
