Machine for automatically cutting out openings, in multiple shapes, of packing boxes

Abstract

The invention relates to a machine for automatically cutting out openings, in multiple shapes, of packing boxes. The machine comprises a bottom plate; a switchable opening-cut device is installed in the middle of the upper end surface of the bottom plate through screws, and a PLC is installed on the bottom plate; the switchable opening-cut device can achieve the function of quickly switching die cutting tool bits, the die cutting speed of the packing boxes is greatly increased, and the working efficiency is improved; two conveying devices are symmetrically installed on the two sides of the upper end surface of the bottom plate and can achieve the effect of automatically conveying the packing boxes subjected to die cutting; in addition, two connecting branched chains are installed between the switchable opening-cut device and the two conveying devices correspondingly; and the effect that the packing boxes conveyed through the conveying devices can smoothly enter the switchable opening-cut device to be processed can be ensured through the connecting branched chains. The machine can achieve the function of quickly switching the die cutting tool bits, so that tool bit replacement time is greatly saved; and moreover, the machine has the advantages of being easy and convenient to operate, simple in technological procedure, high in working efficiency and the like.

Description

technical field [0001] The invention relates to packaging printing machinery and equipment, in particular to an automatic multi-shape cutting machine for packaging boxes. Background technique [0002] The die-cutting process is an important process in the packaging box production process. The die-cutting process can be divided into circular die-cutting, circular die-cutting and flat-flat die-cutting. Among them, the flat die-cutting method can be used in various occasions with different needs. It can not only perform high-speed continuous die-cutting, but also manual paper feeding and semi-automatic die-cutting. It is widely used in various industries and occupies a major position in the domestic packaging box printing and processing market. [0003] Various openings can be seen in the existing packaging boxes, such as squares, circles, diamonds, triangles, etc., to set off the aesthetics of the packaging boxes; in the existing die-cutting equipment, usually need Constantly...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a multi-shape automatic cutting machine for packaging boxes, which can solve the problems of complicated operation, complicated process steps, long time for replacing the cutter head and low work efficiency in the existing packaging box die-cutting process. Realize the rapid conversion function of the die-cutting head, which greatly saves the time of replacing the cutting head, speeds up the die-cutting speed, and has the advantages of simple operation, simple process steps and high work efficiency.
