[0001] This utility model relates to the field of parallel idler roller coating spraying technology, and in particular to a coating spraying device for processing parallel idler rollers. Background Technology
[0002] In industrial production, parallel idlers are a key component of conveying systems and are widely used in many fields such as mining, metallurgy, chemical industry, and ports. Their performance directly affects the efficiency and stability of the conveying system. In order to improve the wear resistance and corrosion resistance of parallel idlers, reduce the coefficient of friction, and extend their service life, it is particularly important to apply a coating spraying treatment to parallel idlers.

Early simple spraying equipment had a low degree of automation and could not be flexibly adjusted according to the shape and size of the idler roller during the spraying process, which easily led to spraying dead corners and serious paint waste, increasing production costs. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0025] In this invention, a U-shaped fixing block 8 is fixedly connected to the outer wall of one side of the spray box 1. A clamping column 9 and a drive wheel 10 are installed inside the U-shaped fixing block 8, and a second servo motor 11 and a second telescopic hydraulic cylinder 12 are respectively installed on the outer side of the U-shaped fixing block 8. The drive end of the second servo motor 11 passes through the U-shaped fixing block 8 and is clamped to one end of the drive wheel 10. The drive wheel 10 and the teeth fixed to the upper end of the clamping column 9 on one side mesh with each other. A connecting groove 13 is opened at one end of the clamping column 9. The second servo motor 11 and the second telescopic hydraulic cylinder 12 facilitate the drive wheel 10 to drive the clamping column 9 to rotate. The telescopic end of the second telescopic hydraulic cylinder 12 passes through the U-shaped fixing block 8 and is rotatably clamped in the connecting groove 13 on the clamping column 9.

[0026] In this utility model, the opening and closing mechanism includes a fixed plate fixed to the inside of the spray box 1, and a first telescopic hydraulic cylinder 16 is hinged between the fixed plates.
