Glue dispenser for glue filling of air cylinders

Abstract

The invention discloses a glue dispenser for glue filling of air cylinders. The glue dispenser comprises an air source, a charging barrel and a glue dispensing gun, wherein air is supplied to the air source through an air compressor; and the charging barrel is used for containing glue. A glue barrel containing a fixed amount of glue can be installed in the charging barrel. A sealing cover capable of being pushed is arranged at the top of the glue barrel. An outlet in the bottom of the glue barrel communicates with a glue outlet formed outside the charging barrel. The glue dispensing gun is connected with the glue outlet through a glue pipe. The top of the charging barrel is provided with a pressure regulating valve communicating with the interior of the charging barrel. The pressure regulating valve is connected to the air source. The charging barrel is vertically installed on a movable trolley. Four movable wheels are installed at the bottom of the trolley. The charging barrel comprises a barrel body and a barrel lid. A round groove matched with the glue barrel is formed in the bottom of the charging barrel. A counter bore allowing the end of the glue barrel to be inserted into is formed in the center of the groove. The glue outlet communicates with the counter bore. The length of the glue barrel is set in the mode that after the glue barrel is inserted into the groove, the top face is just pressed by the barrel lid. The first air cylinder is arranged at the top of the charging barrel. The first air cylinder drives a sealing cover to squeeze the glue. The glue dispensing gun comprises a gun body. The second air cylinder used for squeezing the glue is arranged at the top of the gun body.

Description

technical field [0001] The invention relates to a glue dispensing machine for cylinder glue replenishment. Background technique [0002] The glue dispenser is mainly used to control the liquid adhesive, so that the liquid adhesive stored in the glue dispenser can be injected to the position where the product needs to be bonded during the production process of the product.

The glue is used for sealing, fixing, coating, filling, etc. Strengthen the internal and external structure of the product. Patent No. 201010105245.2 discloses a simple glue dispensing machine, including an air source, an air source controller, a barrel, and a dispensing valve. The air source controller includes an air inlet and an air outlet. The air source is connected, and the air outlet is connected to the dis...

AI Technical Summary

Problems solved by technology

The rubber barrel is close to the inner wall of the barrel, and the glue is pushed out completely by the air pressure rushing into the barrel. The disadvantage is that the air pressure is extremely unstable, and the inner diameter of the barrel is large, the cross-sectional area is large, and the pressure is small. The speed is slow; and because there is no pressure relief device, the pressure relief speed is extremely slow
