High-efficiency inner wall coating spray head

Abstract

The invention discloses a high-efficiency inner wall coating spray head. The high-efficiency inner wall coating spray head comprises a feeding pipe; four spray heads are vertically arranged on the side wall of the feeding pipe; each spray head comprises a coating spraying pipe; the outlet end of the coating spraying pipe is connected with a nozzle; the nozzle is truncated cone shaped; the diameterof one end, far away from the coating spraying pipe, of the nozzle is less than the diameter of one end connected with the coating spraying pipe; a plurality of liquid spraying holes are formed at the liquid outlet end of the nozzle; the internal part of each liquid spraying hole is a truncated cone shaped cavity; a triangular convex tooth is arranged on the inner wall of the liquid outlet end ofeach liquid spraying hole; a shielding cover sleeves the outer wall of the liquid outlet end of the nozzle; a spraying and partitioning net covers the opening of the shielding cover; and the sprayingand partitioning net and the shielding cover wrap the liquid outlet end of the nozzle. The high-efficiency spray head can spray-coat a plurality of wall surfaces of the inner wall of furniture, greatly improves the spray-coating efficiency, can spray-coat uniformly, can improve the spray-coating quality, can achieve good protective effect on the surfaces of the spray head and the furniture and avoids pollution to the spray head caused by mutual collision of the spray head and the furniture.

Description

technical field [0001] The invention relates to a spray head, in particular to a high-efficiency inner wall paint spray head. Background technique [0002] Furniture refers to the category of utensils and facilities necessary for human beings to maintain normal life, engage in production practice and carry out social activities. Furniture also follows the footsteps of the times and continues to develop and innovate. Up to now, there are many categories, different materials, complete varieties, and different uses. It is an important foundation for building a working and living space. Furniture is composed of four factors: material, structure, appearance and function. Furniture generally refers to large items such as wardrobes, tables, beds, and sofas. The main production process of general wooden furniture is material selection, material cutting, carving, assembly, body whitening, primer spraying, oil sanding, color repairing, first-time moderate, gold paste, varnish, old-...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing paint spraying device used for spraying paint on the inner wall of furniture has low efficiency and can only spray one surface one surface at the same time. Moreover, it is easy to spray on clothes, but difficult to clean. The purpose is to provide a high-efficiency inner wall paint nozzle, which can simultaneously spray multiple walls of the inner wall of the furniture, which greatly improves the efficiency of spraying, and not only can be sprayed evenly, but also improves the quality of the paint. The quality of the spraying can also play a good role in protecting the nozzle and the surface of the furniture, so as to avoid the collision between the two and pollute the nozzle
