Paint spraying device for steel plate pretreatment line

Abstract

The invention discloses a paint spraying device for a steel plate pretreatment line. The paint spraying device comprises a chamber body and further comprises an upper rail and a lower rail which are arranged in the chamber body in parallel, an upper paint spraying trolley and a lower paint spraying trolley are mounted on the upper rail and the lower rail correspondingly and provided with an obliquely-arranged upper spraying gun device and an obliquely-arranged lower spraying gun device correspondingly, and an upper telescopic air cylinder and a lower telescopic air cylinder which enable the upper spraying gun device and the lower spraying gun device to stretch out and draw back are arranged on the upper spraying gun device and the lower spraying gun device correspondingly. An upper detecting device and a lower detecting device which are used for detecting the paint spraying concentrations are mounted on one sides of spraying heads of the upper spraying gun device and the lower sprayinggun device, and an upper distance sensor and a lower distance sensor which are used for detecting the distances between the spraying heads and steel plates are arranged on the other sides of the spraying heads of the upper spraying gun device and the lower spraying gun device. By adopting the structure, paint operation can be conducted in an oblique paint spraying mode, the paint spraying face islarge, the uniformity of paint spraying is improved, the situation that the paint spraying thicknesses of different positions are uneven is avoided, the treated steel plate quality is ensured, the manpower and time cost is saved, and through the telescopic air cylinders, the different required paint spraying concentrations can be well adjusted.

Description

Technical field [0001] The invention relates to an accessory device of shot blasting equipment, in particular to a paint spraying device for a steel plate pretreatment line. Background technique [0002] The steel plate pretreatment line usually needs to be painted. The existing paint spraying room generally includes a room body with a track and a painting trolley that reciprocates along the track. The paint trolley is equipped with a spray gun, and the steel plate can be painted by the spray gun. Treatment, although the existing structure can meet the painting requirements, it still has the following defects. On the one hand, due to various factors, the surface of the steel plate cannot be painted uniformly, resulting in thick painting in some places. The thinness seriously affects the use of the steel plate after treatment, especially when the lower spray gun device is facing the bottom surface of the steel plate, not only is it easy to cause paint spots, but also it is easy to...

AI Technical Summary

Problems solved by technology

[0002] The steel plate pretreatment line usually needs to carry out painting treatment. The existing spray booth generally includes a room body, which is equipped with a track and a painting trolley that reciprocates along the track. The spray gun is installed on the trolley, and the steel plate can be sprayed through the spray gun. Although the existing structure can meet the requirements of painting, it still has the following defects. On the one hand, due to various factors, the surface of the steel plate cannot be painted evenly, resulting in thick paint in some places and thick paint in others. Thin, which seriously affects the use of the treated steel plate, especially the lower spray gun device is facing the bottom of the steel plate, which not only easily causes paint spots to concentrate, but also easily causes blockage of the spray gun during the shutdown process. On the other hand, the paint mist diffuses during the spraying process. , easy to contaminate the spraying device
