A glue spraying device of a packing box glue coating machine

Abstract

The invention discloses a glue spraying device for a packing box glue spreader. The glue spraying device comprises a glue spraying head, an adjusting frame and a glue supply barrel. The glue sprayinghead and the glue supply barrel are connected together through an adjusting frame. The glue spraying head is connected with the glue supply barrel through a glue spraying hose to spray glue. A placingplate is arranged at the top end of the glue supply barrel. The adjusting frame and the placing plate are installed together fixedly. The adjusting frame comprises an adjusting rod and two fixed struts. A connecting seat is arranged at the top end of the fixed strut at one end. The adjusting rod penetrates through the connecting seat. An installing seat is arranged on the surface of the adjustingrod. The glue spraying head is installed on the installing seat and comprises a glue holding chamber, glue outlets and spreading heads. A glue outlet plate is arranged at the bottom end of the glue holding chamber. The glue outlets are evenly formed in the surface of the glue outlet plate. The spreading heads is installed in the glue outlets. A plurality of conical mouths are arranged in the spreading heads. Overall glue spreading can be conducted fast, glue spreading is uniform, reasonable glue spreading adjustment can be conducted for different packing boxes, work efficiency of the glue spreader is improved, and the glue spraying device is worth popularization.

Description

technical field [0001] The invention relates to the technical field of packaging box gluing machines, in particular to a glue spraying device of the packaging box gluing machine. Background technique [0002] The glue coating machine is also known as the coating machine, the glue scraping machine, the automatic glue spraying machine, etc. A mechanical device mainly used to apply liquid glue on the surface of textiles, cartons or leather. There are many types of existing glue coating machines, such as: drum glue coating machine, double-acting glue coating machine, double station Lifting glue applicator, etc. The coating machine sprays liquids such as glue or paint onto the required products through air pressure. In the production process of packaging boxes, gluing is a necessary process. The quality of gluing is important to the quality of packaging boxes. However, when the general gluing device is gluing, it is fixed gluing, and there is a problem of uneven gluing, which i...

Problems solved by technology

The coating machine sprays liquids such as glue or paint onto the required products through air pressure. In the production process of packaging boxes, gluing is a necessary process. The quality of gluing is important to the quality of packaging boxes. However, when the general gluing device is gluing, it is fixed gluing, and there is a problem of uneven gluing, which is not conducive to the improvement of the quality of the packaging box.
