a paint sprayer

Abstract

The invention discloses a paint sprayer, which comprises a closed cover, a paint spray pipe, a fixer, a storage barrel, and a mobile vehicle. The paint spray pipe is composed of a scraping device, a connecting rod, a spray pipe, a thread block, and a spray port. Strong viscous nitro paint will remain on the right end of the scraping device, and the rubber block will be stretched under the elastic force of the spring, and the paint scraped off by the scraping block will slide down to the lower end of the pressure rod, so as to avoid paint remaining inside the pipe and prevent The paint dries in the pipe to avoid the diameter of the pipe becoming smaller, and the structure of the scraping block has the effect of enhancing the scraping effect on the inside of the pipe, reducing the degree of paint accumulation, preventing the inside of the pipe from being blocked, and avoiding affecting the transportation of paint. When spraying paint, The blocking mechanism opens to the right side of the scraping device under the pressure of paint spraying, so as to avoid affecting the flow of paint spraying. After the painting is stopped, the blocking plate rebounds under the action of the limit spring inside the limit block to avoid the generation of gaps and prevent residual paint Excessive backflow from the gap.

Description

technical field [0001] The invention relates to the field of painting processing, in particular to a paint sprayer. Background technique [0002] The paint sprayer makes use of the pressure to spray the internal paint on the surface of the object. After the paint solidifies, it achieves the effect of isolating from the air, and the nitro paint has a higher viscosity, and the drying and bonding speed is faster. After spraying, it has a strong covering power. It has stronger protective effect on the surface of the object, but the bucket containing the paint is inconvenient to move due to its heavy weight. The spraying distance of the nitro-lacquer is enhanced through the pipeline connection, and the furniture is sprayed, resulting in a viscous nitro-lacquer after the painting is finished. The base paint will remain inside the pipe and adhere to the inner wall of the pipe. After the paint dries, the diameter of the pipe will become smaller, and when it accumulates to a certain ...
