Spraying device for sofa wooden plates

Abstract

A spraying device for sofa wooden plates comprises a tank body, the upper end of a screw is fixedly connected to the top of the inner wall of the tank body, the screw and a center line of the top of the inner wall of the tank body are collinear, two sides of the screw are provided with slide channels, a sliding sleeve is movably mounted on the screw, the top and bottom of the sliding sleeve are both opened, sliding strips are fixedly mounted on the two sides of the inner wall of the sliding sleeve, the sliding strips are positioned in the corresponding slide channel and can slide along the same, a motor is fixedly mounted on one side of the sliding sleeve, a gear is fixedly mounted on an output shaft of the motor, a screw sleeve is threadedly mounted on the screw, and the screw sleeve is in threaded fit with the screw. After the motor stops operating, a scraper plate never contacts the inner wall of the tank body under the action of a torsion spring, so that adhesion of the scraper plate to the inner wall of the tank body due to long-term idling is avoided; the screw sleeve rotates to drive a rotary shaft to synchronously rotate with the screw sleeve, the rotary shaft can stir adhesive in the tank body through a support rod and a corresponding floater, clotting of the adhesive can be avoided, the adhesive can be sprayed out evenly, and the adhesive can be stored for longer time.

Description

technical field [0001] The invention belongs to the field of furniture processing, in particular to a spraying device for sofa planks. Background technique [0002] During the processing of the sofa, the sponge needs to be pasted on the wooden board. At present, the commonly used method is that the worker sprays the glue evenly on the surface of the raw material to be processed through the glue spraying device, and then pastes it. However, due to the high viscosity of the colloid, it is very easy to hang on the wall. Long-term use will easily cause the colloid to dry and stick to the inner wall of the glue tank. After the workers spray the glue, they need to clean the glue tank immediately, which increases the labor of the workers. Effective device to remove wall hanging phenomenon. Contents of the invention [0003] The invention provides a spraying device for sofa planks to solve the defects in the prior art. [0004] The present invention is achieved through the follo...
