AI Technical Summary

Technical Problem

When processing multi-layer cardboard, the existing color-coated reinforcement device does not have enough weight on the pressure plate to effectively remove air bubbles, resulting in low bonding strength between the color-coated surface and the carton.

Method used

The pressure plate assembly is driven by a cylinder, combined with a ball joint and a force equalization component. The pressure of the pressure plate is controlled by the cylinder and the pressure is distributed by the force equalization component, so that the pressure plate can self-adjust according to the number and thickness of the cardboard layers, ensuring the stable discharge of air bubbles.

Benefits of technology

It enables the stable removal of air bubbles between the colored surface and the cardboard, improves the bond between the colored surface and the cardboard, and protects the cardboard from damage.

Abstract

This application relates to a corrugated cardboard box color-coated surface reinforcement device, belonging to the field of reinforcement devices. It includes a frame and a support, with the support mounted on the frame. Several sets of pressure plate assemblies are provided on the support. Each pressure plate assembly includes a connecting plate, a cylinder, and a pressure plate. The connecting plate is mounted on the support, the cylinder is vertically mounted on the connecting plate, and the pressure plate is located at the output end of the cylinder. This application provides a relatively stable pressure application to the color-coated surface, improving the removal of air bubbles between the color-coated surface and the cardboard.
