Glue gun

Abstract

The invention discloses a glue gun which comprises a glue nozzle, wherein a glue feeding hole is formed in the glue nozzle; a scraper blade is arranged at the head of the glue nozzle; a glue body accommodating cavity is formed in the lower end of the scraper blade; two sides of the glue body accommodating cavity extend towards the head of a nozzle body to form cambered flanges; a through hole is formed in the scraper blade; the lower end of the through hole is communicated with the glue body accommodating cavity; the upper end of the through hole is communicated with the end face of the upper end of the scraper blade; the through hole in the upper end of the scraper blade is connected with a hollow hose; the other end of the hollow hose is connected with a glue body collection device. When the glue gun is used for dispensing glue, redundant glue bodies in a slit can be scraped to another slit with a small amount of glue bodies under the action of the scraper blade, and the residual glue bodies are sucked into the glue body collection device. Therefore, the glue gun has the beneficial effects that the glue dispension is uniform, the redundant glue bodies can be recycled, the waste of glue bodies is effectively reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a glue applying tool, in particular to a glue applying gun. Background technique [0002] At present, the production of cars puts forward higher and higher requirements on the airtightness of the body. This work is mainly completed by welding, painting and gluing processes, mainly for the lap joints of side panels, front and rear floors, engine compartments, and front and rear wheel covers. The common ones are expansion glue, edge wrapping glue or glass glue, so as to improve the sealing and waterproof performance. The quality of glue not only affects the aesthetics of the car body, but also directly affects the sealing performance of the car body. In the automobile manufacturing process It plays a vital role, but now the common glue gun generally includes the glue gun body and the glue gun nozzle, the glue cartridge is installed in the gun barrel, the wrench is pulled, and the ejector rod on the glue gun body holds the glue S...

Problems solved by technology

[0004] In order to overcome the problem that the glue gun in the prior art is difficult to achieve uniform glue discharge when used, resulting in too much glue in some places causing waste, and too little glue in some places and poor sealing performance, the present invention provides A glue gun that applies glue evenly and the excess glue can be recycled again
