AI Technical Summary

Technical Problem

In the prior art, the laminating device for packaging printing cannot effectively fix the printed packaging box during printing, resulting in poor printing effect.

Method used

A packaging printing laminating device is adopted, including a mounting frame, a U-shaped plate, a printing packaging box positioning and fixing mechanism, and a printing packaging box laminating mechanism. By driving a bidirectional lead screw and a hydraulic cylinder with a motor, combined with a guide component and a buffer component, the device can achieve rapid positioning and flexible lamination of the packaging box.

Benefits of technology

It achieves stable fixation and high-quality lamination of printed packaging boxes, avoids damage to packaging boxes during the printing process, extends the service life of the equipment, and reduces production costs.

Abstract

This utility model discloses a laminating device for packaging printing, belonging to the technical field of laminating devices. It includes a mounting frame with supporting legs at its lower corner, a conveyor belt at its upper end, and multiple sets of packaging box bodies placed on the upper end of the conveyor belt. A U-shaped plate is positioned at the center of the upper end of the mounting frame, with a controller on the outer side of the U-shaped plate and an infrared sensor at the inner edge of the U-shaped plate. A printing packaging box laminating mechanism is positioned at the center of the upper end of the U-shaped plate. This utility model achieves rapid positioning and fixing of the packaging box by setting up a printing packaging box positioning and fixing mechanism, using a bidirectional lead screw, nut blocks, a sliding plate, and a motor, combined with a guide assembly and a positioning plate. The motor drives the bidirectional lead screw to rotate, causing two sets of nut blocks to move the sliding plate along the guide assembly towards or away from each other. The anti-slip texture on the positioning plate firmly clamps the packaging box, preventing it from shifting during the laminating process.
