Adhesive tape pushing mechanism, hot melt adhesive gun and automatic liquid adhesive extrusion process

Abstract

The invention discloses an adhesive tape pushing mechanism, a hot melt adhesive gun and an automatic liquid adhesive extrusion process. The adhesive tape pushing mechanism drives a reduction gear setthrough a power assembly to drive two oppositely-arranged extrusion rollers to rotate, and an adhesive tape is extruded between the two extrusion rollers and is continuously supplied through rotationdriving of the extrusion rollers; the hot melt adhesive gun synchronously heats a heating body through a power supply assembly and starts the adhesive tape pushing mechanism to supply the adhesive tape, the diameter of a hollow cavity in the heating body is slightly smaller than that of the adhesive tape, and the speed of extruding liquid adhesive from an adhesive outlet hole is uniform; and according to the automatic liquid adhesive extrusion process, after the heating body is preheated through the same power supply assembly, the heating body continues to be heated, the adhesive tape pushingmechanism in the hot melt adhesive gun is synchronously started, after a power control switch is mechanically triggered through a power trigger switch to switch on an automatic adhesive extrusion loop, the liquid adhesive can be continuously and automatically extruded, the uniformity of continuous adhesive extrusion can be improved, manpower is effectively saved, and the adhesive tape pushing mechanism, the hot melt adhesive gun and the automatic liquid adhesive extrusion process are used for the field of hot melt adhesive guns.

Description

technical field [0001] The invention belongs to the field of hot-melt glue guns for industrial equipment, and more specifically relates to a rubber strip pushing mechanism, a hot-melt glue gun and an automatic extrusion process for liquid glue. Background technique [0002] Hot melt glue gun is a decoration tool, widely used in electronics factories, food factories, packaging factories, etc., to bond products through hot melt adhesive strips. [0003] Hot melt glue gun, with precise breaking effect and various nozzles, can meet the requirements of different production lines. However, the existing hot-melt glue guns control the amount of glue output by manually controlling the extrusion mechanism. When a large amount of hot-melt glue needs to be used, the manual extrusion method is not sustainable, and the glue output is controlled by manpower. , not even enough, at the same time, the operator is more difficult to use. Contents of the invention [0004] The main purpose o...
