Full-automatic high-viscosity glue extruding device

Abstract

The invention discloses a full-automatic high-viscosity glue extruding device. The full-automatic high-viscosity glue extruding device comprises a rack and a glue barrel arranged in the rack. Glue leaking holes are formed in the bottom of the glue barrel, a frequency conversion motor, a gear pump, an air cylinder and an air cylinder pressing disc are included, the frequency conversion motor is intransmission connection with an input shaft of the gear pump, the gear pump is arranged on the bottom of the glue barrel, a glue outlet valve body is arranged on the surface, the glue leaking holes communicate with a feeding opening of the gear pump, the air cylinder is fixedly arranged on the upper end of the rack and located above the glue barrel, an air cylinder pressing disc is fixedly connected with a piston rod of the air cylinder, the air cylinder pressing disc is arranged in the glue barrel, the side is attached to the inner wall of the glue barrel, and an exhaust hole is formed in thesurface of the air cylinder pressing disc. The glue extruding speed is high, the efficiency is high, the glue outlet amount is above 100 g / min, glue cannot generate bubbles, and the extruded glue isgood in bonding effect.

Description

technical field [0001] The invention relates to the field of glue extrusion, in particular to a fully automatic high-viscosity glue extrusion device. Background technique [0002] In industrial production, some products and parts of equipment need glue to connect. In order to ensure the stability of the connection, high-viscosity glue is generally used, and its viscosity is usually 10000-50000MPa.s. Due to the high viscosity, the glue is usually extruded from the rubber barrel by high-pressure air of 0.4-0.6MPa, but this method has certain defects, such as slow extrusion speed and low efficiency, and the glue output is only 10-30g / min, and will cause the glue to produce air bubbles, reducing its bonding effect; in order to increase the glue output speed, the air pressure is usually increased, but there will be certain safety hazards, exceeding the pressure range of the glue barrel will cause the glue barrel to burst or explode. Contents of the invention [0003] In order...
