Paperboard gluing machine

Abstract

The invention relates to the technical field of processing and manufacturing of paperboards, and discloses a paperboard gluing machine. The paperboard gluing machine comprises a machine table and a machine frame. A gluing wheel, a motor and an air bellows are rotationally connected with the machine frame. Blades are arranged in the air bellows and fixedly connected with the motor. A slide pipe communicating with the inside of the air bellows is arranged at the bottom of the air bellows. An inner pipe with a closed top end is connected inside the sliding pipe in a sliding mode and provided witha plurality of through holes. The bottom end of the inner pipe is connected with an air guide pipe. The gluing wheel is connected with a power mechanism. A cavity communicating with the air guide pipe is formed inside the gluing wheel. The gluing wheel is provided with an eccentric post. The eccentric post is hinged to a push rod. The push rod is hinged to the bottom end of the inner pipe. An arc-shaped gluing plate is arranged on the side of the gluing wheel and comprises a plurality of expansion teeth and gluing balls distributed alternately in sequence. The expansion teeth communicate withthe cavity. The gluing balls are provided with spraying holes and contain glue. The coving area of the glue on the paperboards can be increased, and the gluing effect is improved.

Description

technical field [0001] The invention relates to the technical field of cardboard processing and manufacturing, in particular to a cardboard gluing machine. Background technique [0002] In the process of product circulation, in order to protect the product, facilitate storage and transportation, and promote sales, a paper box is usually used to package the product. Carton packaging is the most widely used packaging method. It is different from wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging. Carton packaging has the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost. It is widely used in sales packaging and transportation packaging of commodities. [0003] The carton is made of folded cardboard. In the process of cardboard processing, in order to ensure the hardness of the cardboard and prevent the cardboard from loosening, glue is usually used to bond multiple layers of ...

AI Technical Summary

Problems solved by technology

In this process, since the gluing wheel is circular and fixed on a certain part of the processing table to rotate, and the cardboard is flat, when the gluing wheel contacts the cardboard, the cardboard is positioned at the center of the gluing wheel. In the tangential direction, only one part of the cardboard can be in contact with the gluing wheel to be stained with glue, resulting in a small coating area of ​​the glue on the cardboard, poor coating effect, and affecting the adhesion of the next layer of cardboard
