Pressing mechanism based on printing and paper packaging die-cutting machine

Abstract

The invention discloses a pressing mechanism based on a printing and paper packaging die-cutting machine, relates to the field of matching mechanisms of die-cutting machines, and solves the problems of poor operation flexibility and inconvenience in use of the existing pressing mechanism that a cutting turntable and a conveying guide roller are sequentially adjusted in a sliding way step by step.The pressing mechanism based on the printing and paper packaging die-cutting machine comprises a frame, a square push rod and a slip ring, wherein two rotating shafts are rotatably supported at intervals in the frame, and four rotating discs and four conveying top rollers sleeves and arranged on the upper rotating shaft and the lower rotating shaft respectively; and two positioning collars are symmetrically welded on the front and rear ends of the rotating disc and the central jack of the conveying top roller. The spacing between the four rotating discs and the four conveying top rollers can be adjusted according to the size of wrapping paper and the cutting spacing required by different requirements, the flexibility is high, and the rotating discs and the conveying top rollers can be adjusted and slid conveniently.

Description

technical field [0001] The invention relates to the technical field of supporting mechanisms for die-cutting machines, in particular to a pressing mechanism based on printing and paper packaging die-cutting machines. Background technique [0002] In the printing and slotting process of cardboard, the cardboard needs to be slotted and trimmed. During the processing, each slot or edge is processed by two slotting knives or slotting knives with a certain relative position. Edge cutter to finish. Because in the process of carton processing, it is necessary to press the packaging paper to implement normal edge trimming at the slot, so it is urgent to design a pressing mechanism for printing and paper packaging die-cutting machines. [0003] In the existing pressing mechanism, the distance between the cutting turntable at the top and the transmission guide rollers at the bottom cannot be adjusted properly or the sliding adjustment of the spacing is cumbersome. It is necessary to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pressing mechanism based on printing and paper packaging die-cutting machines to solve the problem that the distance between the top cutting turntable and the bottom conveying guide roller cannot be adjusted or the distance between the multiple cutting turntables and the bottom conveying guide rollers proposed in the background art The slip adjustment operation process is cumbersome, and the cutting turntable and the transmission guide roller need to be adjusted step by step, and the operation flexibility is poor. The use is more inconvenient.
