Die cutting machine

Through the coordinated design of the horizontal guide assembly and the vertical guide assembly of the die-cutting machine, combined with the coordination of the pre-tightening plate and the support roller, the problems of cumbersome manual adjustment of the guide structure and incomplete waste separation in traditional die-cutting machines have been solved. Precise guidance of material feed and stable separation of waste and finished products have been achieved, thereby improving production efficiency.

AI Technical Summary

Technical Problem

During the material feeding and unloading process, traditional die-cutting machines have problems such as cumbersome manual adjustment of the guide structure, low precision, and frequent die-cutting misalignment; waste material separation is not complete, and tension fluctuations lead to incomplete material removal.

Method used

The horizontal guide assembly and the vertical guide assembly are used for collaborative guidance. The pre-tightening plate and the support roller cooperate to achieve stable tensioning of the material. Combined with the feeding assembly and the material transfer assembly, the rapid separation and classified output of the material can be achieved.

Benefits of technology

It improves the accuracy and stability of material feeding, avoids die-cutting dislocation, ensures the complete separation of waste materials and finished products, simplifies the unloading and waste removal processes, and improves production efficiency.

Abstract

The invention relates to the technical field of printing and packaging, in particular to a die-cutting machine which comprises a machine body, the front side and the rear side of the machine body are provided with a feeding table and a discharging table respectively, and the die-cutting machine further comprises a die-cutting assembly, a vertical guide assembly, a horizontal guide assembly and a material guide assembly. And the pre-tightening plate is synchronously driven to press downwards, so that the buffering cushion is matched with the supporting roller, uniform pre-tightening force is formed on the waste, and the front edge and the rear edge of the waste are kept stable in tension degree (not tight or loose). By means of the design that die cutting and pre-tightening are synchronous, the stripping problem caused by fluctuation of the tension degree of a traditional structure is avoided from the source; the pressing plate is driven by the lifter, materials are accurately pressed down through the through hole of the pre-tightening plate, the materials and waste materials are separated in a stable tensioning state in cooperation with supporting of the supporting roller, and the material stripping thoroughness is remarkably improved. Meanwhile, material deformation or waste material tearing caused by hard pressing can be avoided through the elastic buffering effect of the buffering pad.
