Description

TECHNICAL FIELD

[0001] The utility model relates to double -sided adhesive tape production technical field, concretely is a kind of glue spreading device for double -sided adhesive tape production. BACKGROUND

[0002] The glue spreading device for double -sided adhesive tape production is a device for uniformly spreading glue on the surface of a substrate such as paper, film, cloth, etc. It is one of the most important links in the production of double -sided adhesive tape. Its main function is to spread appropriate glue on the substrate to ensure that the adhesion, uniformity and thickness of the glue meet the production requirements.

[0003] The glue spreading device disclosed in Chinese Patent No. CN220738305U can hold and fix the mute cotton at the top end of the placement plate through the holding mechanism, preventing the mute cotton from moving during glue spreading, which can cause poor spreading effect. The moving frame is moved by the second screw, which drives the support plate to move. The support plate is moved downward by the electric push rod, which spreads glue on the top end of the mute cotton. The glue on the top end of the mute cotton is leveled by the compression roller and the leveling plate, preventing the glue from dripping and affecting the subsequent use of the mute cotton. However, the overall functionality of the glue spreading device is low, and long-term use can cause dust to adhere to the glue spreading port, causing the glue spreading port to be blocked, affecting the stability and uniformity of the subsequent use of the glue spreading device.
