Glue dispenser stable in pressure

Abstract

The invention discloses a glue dispenser stable in pressure. The glue dispenser comprises an air source supplying air through an air compressor, a material barrel capable of containing glue and a glue dispensing gun. A glue barrel storing the curing agent amount of glue can be arranged in the material barrel, a sealing cover capable of being pushed is arranged on the top of the glue barrel, and an outlet in the bottom of the glue barrel communicates with a glue outlet formed in the outer portion of the material barrel. The glue dispensing gun is connected with the glue outlet through a glue pipe. A pressure regulating valve communicating with the interior of the material barrel is arranged on the top of the material barrel and connected to the air source. The material barrel comprises a barrel body and a barrel cover. A circular groove matched with the glue barrel is formed in the bottom of the material barrel. A counter bore in which the end portion of the glue barrel can be inserted is formed in the center of the groove, the glue outlet communicates with the counter bore, and the length of the glue barrel is set to achieve the purpose that after the glue barrel is inserted in the groove, the top face of the glue barrel is pressed right by the barrel cover. The barrel cover is further provided with a safety valve. A first air cylinder is arranged on the top of the material barrel, a drive rod of the first air cylinder stretches into the material barrel, a piston is arranged at the tail end of the drive rod of the first air cylinder, and the piston and the glue barrel are matched and pressed on the sealing cover.

Description

technical field [0001] The invention relates to a glue dispenser with stable pressure. 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. Dispensing machines are widely used in electronics, electrical, communication equipment, automobile industry, medical industry, mobile phone industry, toys, glasses, clocks and other industries. 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 dispensing valve and th...

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 air pressure is extremely unstable, and the inner diameter of the barrel is large, the cross-sectional area is large, the pressure is small, and the pushing speed is slow. ; If you want to speed up, you need to increase the air pressure, and there is no safety device on the barrel, which is very dangerous
