Glue gun

Abstract

The invention provides a glue gun which comprises a base for fixing a glue barrel capable of storing glue. The propelling device is used for extruding the rubber material in the rubber barrel cavity and comprises a lead screw, a guide sleeve and a piston which are arranged in the rubber barrel cavity, the guide sleeve is connected with one end of the lead screw through a ball nut, and the piston is connected with the other end of the lead screw through a bearing; the motor is arranged on the base, and a main shaft of the motor penetrates through the rubber sleeve and is connected with the guide sleeve; the motor is driven, the guide sleeve rotates along with a motor spindle, the screw rod synchronously converts the rotating motion into linear motion relative to the guide sleeve through the ball nut, and the piston linearly moves along with the screw rod; the glue nozzle is used for effectively discharging the extruded glue in the glue barrel cavity, and the glue nozzle is communicated with the glue barrel through a pressure reducing valve; the motor main shaft rotates to drive the propelling device to extrude glue in the glue barrel cavity, the microprocessor opens the pressure reducing valve and adjusts the throttling area of the pressure reducing valve according to feedback of the pressure sensor, the glue outlet amount can be freely controlled, and uniform and continuous glue outlet is achieved.

Description

technical field [0001] The invention mainly relates to the technical field of gluing equipment, in particular to a gluing gun. Background technique [0002] A glue applicator is a type of equipment commonly used in the manufacturing industry, which can apply a fluid colloidal material, such as a sticky resin, to a part to be processed so that it can be used to glue other parts. [0003] In the use of traditional glue tools, compressed air is usually used to push the glue liquid from one end to the other end of the glue nozzle. As a result, the glue output accuracy is not high. [0004] In addition, after the traditional glue tool is used, the residual glue in the glue nozzle will still slowly flow out from the glue nozzle, forming a "drawing" phenomenon. This "drawing" phenomenon not only wastes raw materials, but also causes pollution to the parts that do not need to be glued for processing parts. SUMMARY OF THE INVENTION [0005] In view of the above-mentioned defects...
