Automatic glue coating machine for production of packaging box and control method

Abstract

The invention discloses an automatic glue coating machine for the production of packaging boxes. The automatic glue coating machine includes a machine frame, a crossbeam, a crossbeam drive motor, a glue coating cylinder mounting member, a mounting member drive motor, a glue coating cylinder, a glue coating solenoid valve, a glue coating head, a material dividing cylinder, a material dividing pushplate, a clamping cylinder, a clamping push plate, a material blocking cylinder, a material blocking stop rod, a first proximity sensor, a second proximity sensor, a third proximity sensor, a fourth proximity sensor and a controller, the components are connected correspondingly to form an automatic control structure. The invention further discloses a control method of the automatic glue coating machine for the production of the packaging boxes. The automatic glue coating operation control over parts to be subjected to glue coating is realized. The precise automatic control over the whole process of the glue coating operation in the production of the packaging boxes is realized. The automatic glue coating machine has the advantages that glue coating thickness and position are precise, gluecoating quality is good, the number of defective goods is less, glue liquid is saved, the glue coating speed is high and the efficiency is significantly improved, and is especially suitable for glue coating operation on bases of the packaging boxes.

Description

technical field [0001] The invention relates to an automatic equipment for packaging box production, in particular to an automatic gluing machine for packaging box production and a control method. Background technique [0002] Packaging boxes are widely used, the demand is increasing, and now the living standard is getting higher and higher, and people have higher and higher requirements for the aesthetics of packaging boxes, such as bottled wine packaging boxes, whose appearance is very attractive to users. Therefore, how to scale and automate the production of packaging boxes with high efficiency and high quality has become a problem that the packaging industry needs to solve. [0003] In the production process of the packaging box, the base and the inner box need to be assembled by gluing and pressing. The traditional assembly method is mainly done by hand. It is necessary to brush glue on the surface of the base (industrial cardboard, wood board, plastic board or fiberbo...

AI Technical Summary

Problems solved by technology

[0003] In the production process of the packaging box, the base and the inner box need to be assembled by gluing and pressing. The traditional assembly method is mainly done by hand. It is necessary to brush glue on the surface of the base (industrial cardboard, wood board, plastic board or fiberboard, etc.) (also known as gluing), and then align the bottom of the inner box with the base for pressing; in the gluing process, at least the operator needs to complete the three actions of base discharge, gluing and handling, and there are the following defects : The processing quality is greatly affected by personal factors such as workers' experience and sense of responsibility, and the product quality is not guaranteed. There are often problems such as incorrect glue application position, uneven thickness of glue application, firm bonding or waste of glue, resulting in product overflow or glue opening; Manual completion is time-consuming, laborious, slow, and inefficient, and there are problems such as the base being dropped and damaged; it is difficult to effectively connect with other processes of packaging box production to form an entire automated production line, which reduces the automation level and product quality of the entire packaging box production line and production efficiency
