AI Technical Summary

Technical Problem

Traditional cardboard box forming processes involve chemical adhesives that pollute the environment, have long curing times, uneven coating, and rigid molding that can easily damage the corrugated core. Furthermore, the equipment structure is cumbersome and difficult to adapt to high-speed production.

Method used

Using glue-free integrated molding equipment, hydraulic and ultrasonic heating technologies are employed. Through the cooperation of negative pressure plates and side suction plates, precise coating and rapid bonding of cardboard are achieved, avoiding damage to the corrugated core by rigid molding, and adapting to high-speed production.

Benefits of technology

It achieves glue-free, precise coating, and stable molding, improving production efficiency, avoiding environmental pollution and equipment complexity, and enhancing the overall strength of the cardboard boxes.

Abstract

The application discloses a paper packaging box glue-free integrated forming equipment and process, wherein rotatable negative pressure plates and side suction plates are arranged on four sides of a male die, so that when the male die rotates to a set position above a paperboard, the negative pressure plates can be pressed on a to-be-formed surface of the paperboard to perform adsorption, and the side suction plates can adsorb one side of a to-be-pressed part of the paperboard to an inclined surface; at this time, the male die continues to rotate to leave the position, and the negative pressure plates and the side suction plates can synchronously rotate to serve as female dies, drive the adsorbed paperboard to be attached to four side walls of the male die, complete a closing operation of the carton, and avoid a rigid collision structure of existing rigid male dies and female dies, which can cause crushing and damage of a corrugated core of the corrugated paperboard in a pressing process and affect the overall strength of the carton.
