Paint coating spraying device and application method thereof

Abstract

The invention discloses a paint coating spraying device which comprises a bearing device, a paint coating storage device and a spraying device. The paint coating storage device and the spraying deviceare both mounted on the bearing device. The paint coating storage device comprises a paint coating storage bucket and a flow control valve mounted on the paint coating storage bucket. The flow control valve divides the paint coating storage bucket into an upper bucket body and a lower bucket body. The flow control valve comprises a supporting device fixed to the inner wall of the paint coating storage bucket, a connecting device fixed to the outer wall of the paint coating storage bucket and an adjusting device mounted on the supporting device. The spraying device comprises a sliding block, the sliding block is mounted on a threaded column, and a paint spray head assembly is fixed to one end of an L-shaped mounting rod. According to the paint coating spraying device, large-area, efficientand uniform spraying to a wall can be achieved, and the spraying efficiency and the spraying quality can be improved; and through the arrangement of the flow control valve, paint coating uniformity can be improved, and constant pressure of spraying and spraying quality can also be improved.

Description

technical field [0001] The invention belongs to the technical field of paint spraying, and in particular relates to a paint spraying device and a using method thereof. Background technique [0002] Wall painting is an important part of building construction and decoration. Low-grade and inferior paint has uneven luster, is prone to yellowing, brittleness, cracks and peeling off, which not only wastes high-quality boards, but also destroys the overall decoration effect. High-quality paint It can not only make up for the defects of previous decoration, but also improve the taste and grade of the whole decoration. Besides the quality of the paint itself, the painting process is also very important. At present, the wall paint is sprayed by the construction staff with a spray gun, due to manual operation There are large differences, which easily lead to uneven thickness of the paint surface, affect the construction quality, and are labor intensive.

[0002] Wall painting is an important part of building construction and decoration. Low-grade and inferior paint has uneven luster, is prone to yellowing, brittleness, cracks and peeling off, which not only wastes high-quality boards, but also destroys the overall decoration effect. High-quality paint It can not only make up for the defects of previous decoration, but also improve the taste and grade of the whole decoration. Besides the quality of the paint itself, the painting process is also very important. At present, the wall paint is sprayed by the construction staff with a spray gun, due to manual operation There are large differences, which can easily lead to uneven thickness of the paint surface, affect the construction quality, and the labor intensity is high

[0003] Chinese patent CN206240695U discloses a spraying structure of a wall surface spraying device. In this scheme, there are rollers hinged on the lower side of the mobile base, and the rollers are directly controlled by the motor, so as to realize the automatic walking of the mobile base. The nozzle passes through the hose and the tank. The body is connected, and the hose is also connected with a suction pump, which pressurizes the nozzle through the pump and sprays it out through the nozzle. During the painting process, the moving base can walk at a constant speed, and at the same time, the power part drives the lifting platform to reciprocate and rise at a constant speed. Therefore, the paint can be evenly sprayed on the wall, and the spray quality is higher. For the position that is difficult to spray at the corner of the wall, the turntable can be rotated to adjust the direction of the nozzle so that the nozzle can spray toward the corner, which is more convenient to use. However, in this scheme, the lifting platform is driven by the operation of the traditional lifting cylinder piston rod. Its structure is single, and the lifting process is not stable enough, which leads to poor painting effect on the wall.
