A set of rotating shafts 33 is provided at both the upper and lower ends of the middle end of the working chamber 1. A set of adhesion mechanisms 34 is provided at the outer ends of both sets of rotating shafts 33. A set of collection mechanisms 35 is contacted at the right end of each adhesion mechanism 34.

[0028] The drive box 31 has a set of transmission gears 311 at both the upper and lower ends. The two sets of transmission gears 311 are connected by two sets of auxiliary gears 312. The two sets of transmission gears 311 and the two sets of auxiliary gears mesh with each other. The drive shaft of the motor 32 extends through the drive box 31 and is connected to the front end of the lower transmission gear 311, which can drive it to rotate.

Furthermore, the front ends of the two sets of rotating shafts 33 extend through the drive box 31 and are connected to the rear ends of the two sets of transmission gears 311. The rotation of the two sets of transmission gears 311 can drive the two sets of rotating shafts 33 to rotate relative to each other.

[0029] Please see Figure 2-6 This utility model provides a dust removal device for pretreatment of metal surface spraying. The adhesion mechanism 34 includes an inner sleeve 341, a deformation layer 342, an outer layer 343, and a spring 344. A set of inner sleeves 341 is connected to the outer side of the rotating shaft 33. The outer end of the inner sleeve 341 is provided with a deformation layer 342. The deformation layer 342 is made of rubber, which has good extensibility and resilience, good wear resistance and compression resistance, can be deformed under force, and can rebound and recover after the force is released. The outer layer 343 is connected to the outer side of the deformation layer 342. The outer layer 343 is made of silicone, which has good elasticity and softness, and strong adsorption properties, easily adsorbing dust and hair. This device can adsorb dust from the surface of metal workpieces. A gap exists between the inner sleeve 341 and the deformation layer 342. The inner sleeve 341 is connected to the inner side of the deformation layer 342 via a spring 344. The spring 344 can cooperate with the deformation and rebound of the deformation layer 342 to improve its performance. Furthermore, the opposing ends of the upper and lower adhesive mechanisms contact and press against each other, squeezing the upper and lower surfaces of the metal workpiece. This allows the outer layer 343 to fully contact the metal workpiece, improving the dust adsorption effect. It is also suitable for metal workpieces with curved deformation to meet different user needs.

[0030] Please see Figure 1-6 This utility model provides a dust removal device for pretreatment of metal surface spraying.

A set of scrapers 352 is inclinedly connected to the top surface of the placement rack 351 near the outer layer 343. The other end of the scraper 352 can contact the outer side of the outer layer 343. The upper placement rack 351 is located at the right end of the upper outer layer 343, and the lower placement rack 351 is located at the left end of the lower outer layer 343, corresponding to the rotation direction of the outer layer 343, which is conducive to scraping and collecting the dust on its outer side. A set of collection boxes 53 is provided inside the placement rack 351. The dust scraped off by the scraper 352 can fall into the collection box 53 through its surface. The front end of the collection box 53 extends through to the front end of the working chamber 1 and is connected to a set of handles 354, which makes it easy to take out the collection box 53 and process the collected dust.

[0031] The working principle is as follows:

[0032] In use, the metal workpiece can be fed into the working chamber 1 through the right end port 2. The support roller 22 in the right end port 2 can support the bottom of the metal workpiece. The left end of the metal workpiece can pass between the two sets of rotating shafts 33 and squeeze the deformation layer 342 and the spring 344, so that the outer layer 343 can fully contact its surface and adsorb dust. Then, the surface of the metal workpiece can be adsorbed by the upper and lower sets of dust suction modules 41 to remove dust again. Finally, the metal workpiece can be sent out through the left end port 2 and the surface of the metal workpiece can be cleaned for the third time by the cleaning block 23 in the left end port 2 to improve the dust removal effect.
