Circulation-washing single-component gluing head

Abstract

The invention relates to a circulation-washing single-component gluing head. A pressure adjusting part and a first driving part form a butting relationship, the pressure of a gluing part is adjusted by the pressure adjusting part through the first driving part; the first driving part and the gluing part form a butting relationship, and the first driving part is used for driving the switching on and off of the gluing part to allow the gluing part to be in a glue discharging state or a glue discharging stopping state; a material returning part forms a communication relationship with the first driving part and the gluing part, and the material returning part is used for material returning under the control of the first driving part when the gluing part is at the glue discharging stopping state; a second driving part and the material returning part forms a butting relationship, and the second driving part is used for driving the switching on and off of the material returning part to allowthe material returning part to be in a glue returning state or a glue discharging stopping state; a cleaning part forms a communication relationship with the gluing part, and the cleaning part is usedfor washing the gluing part when the gluing part is at the glue discharging stopping state.

Description

technical field [0001] The invention relates to a gluing head, in particular to a cycle cleaning single-component gluing head. Background technique [0002] Gluing is the process of applying liquid glue to the surface of textiles, cartons or leather. Gluing equipment generally sprays liquids such as glue or paint onto the desired product by air pressure. The gluing head, as the gluing part of the gluing equipment, directly affects the quality of gluing. At present, there are many types of gluing heads at home and abroad, among which according to the structure of the valve body switch of the glue outlet, it can be divided into shaft movement, cup movement, and external glue valve control. [0003] The Chinese patent with the publication number CN104259051B discloses a shaft-moving gluing head for gluing equipment, which uses a piston to drive a transmission shaft, and the transmission shaft drives the stirring blade to move along the axis. The cone at the lower end of the s...

AI Technical Summary

Problems solved by technology

[0004] The gluing head of the prior art is only limited to gluing, and the cleaning of the gluing head cannot be realized, and the glue will be recycled. After the gluing equipment is used, a part of the glue will remain inside the gluing head. When it is used next time, due to the glue Residue and solidification, cannot effectively control the glue output of the glue applicator, affects the uniformity of glue application, and cannot accurately control the glue outlet from the glue applicator
