Novel glue smearing gun

Abstract

The invention relates to a novel glue smearing gun, in particular to a tool for spraying or smearing glue. The front end of the glue smearing gun provided by the invention is additionally provided with a glue charging-breaking start-stop device, and the rear end of the glue smearing gun is provided with an automatic propulsion device, thereby forming a secondary control system; a start-stop block of the glue charging-breaking start-stop device is a cylinder with the same diameter as a gun groove; a glue discharging channel is arranged in the center of the start-stop block; the inner side of the glue discharging channel is provided with an inner silk spinning opening connected with a glue pot silk opening, and the outer side of the glue discharging channel is provided with an outer silk spinning opening connected with a glue nozzle; a glue charging-breaking steel sheet jack is arranged on the start-stop block perpendicular to the glue discharging channel; the lower part of the start-stop block is provided with a groove; a return spring and a shift rod are arranged in the groove; a steel sheet glue discharging hole and a shift hole are formed on a glue charging-breaking steel sheet; the lower part of the glue charging-breaking steel sheet is provided with the return spring; the rear side of the return spring is provided with the shift rod; and the rear end of the shift rod is connected with a pull rod. The upper part of a braking trigger of a propulsion part is connected with a braking pin through a rivet; the lower side of the push rod is provided with a clamping groove matched with a braking pin slope-shaped plug; and a thrust spring and an adjustable fixed plate are arranged between a tension handle and a gun handle at the rear part of the pull rod, thereby forming the propulsion device.

Description

technical field [0001] The invention relates to a tool for spraying or applying colloids. Background technique [0002] In the decoration process of modern buildings, glue guns are often used, such as the sealing of the frames of doors and windows, the injection of glue in the gaps of glass and stone curtain walls, and the stitching of wall gaps, etc. all require the use of glue guns. [0003] The prior art close to the present invention is patent number: 200820093505.7, name: a glue gun and patent number: 200720059014.6, name: utility model patent of glue gun. The feeding device of the glue gun of the above products is manually propelled, and the grip force of the hand is used to make the handle move back and forth, and drive the lever to push the lever forward. Existing glue gun has the following disadvantages: [0004] 1. There are many parts in the feeding device of the glue gun, and the processing of size and shape requires very precise processing to achieve better re...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to provide a new type of glue gun to solve the problem that there are many parts in the prior art, the manufacturing process is complicated, the glue output cannot be freely controlled, the quality of glue injection is affected, the glue is wasted, the service life of the glue gun is short, and the operation is difficult. Complicated, labor-intensive to push by hand, low-quality gluing, etc.
