Some of the suspended paint liquid is not completely eliminated, resulting in a large amount of suspended paint liquid in the air in the spray booth. When spraying other products, the suspended paint liquid in the air may contact the surface of other products, resulting in different paint colors during spraying, thereby reducing the spraying effect, and even the paint mist may spread to the outside world and be absorbed by the human body, causing adverse effects on the health of the staff.

Since the driving gear 140f is meshed with the second rack 130e, the second rack 130e When the rack 130e moves, it will cause the driving gear 140f to rotate, so that one of the rotating rollers 140b drives the exhaust plate 140a to rotate, and through the rotating plate 140c and the protrusion 140g at the bottom of the rotating roller 140b moving in the inner groove of the movable plate 140d, multiple exhaust plates 140a and rotating rollers 140b can be rotated, so that wind force is generated inside the device, which can blow the paint mist onto the water curtain plate 103 and purify the paint mist through the water curtain.

[0030] In this embodiment, when the rotating rod 120a rotates, the second rotating shaft 210c can be rotated through the synchronous belt 210a and the synchronous pulley 210b, so that the first screw rod 220a rotates accordingly. Since the slider 220c is in the lifting groove 101b, and one of the sliders 220c is threadedly connected to the first screw rod 220a, when the first screw rod 220a rotates, it drives the slider 220c to move up and down, so that the scraper 220d can move up and down on the water curtain plate 103, so that the scraper 220d can clean the paint blocks on the water curtain plate 103, so as to avoid the paint blocks blocking the pores on the water curtain plate 103 after long-term use, resulting in uneven water curtain, which affects the water curtain. The paint mist is captured effectively; since the first rack 201 is meshed with the connecting gear 230b, when the slider 220c drives the scraper 220d to rise and fall, the connecting gear 230b can be rotated to drive the second screw rod 230c to rotate, so that the scraper block 230d moves on the scraper 220d to clean the paint blocks attached to the scraper 220d; further, since the first screw rod 220a is a reciprocating screw rod, the scraper 220d can be reciprocated on the water curtain plate 103, and since the second screw rod 230c is a reciprocating screw rod, the scraper block 230d can be reciprocated on the scraper 220d, which is convenient for cleaning the scraper block 230d and the scraper 220d.

The third bevel gear 310c is fixedly connected to the bottom of the first screw rod 220a, one end of the third rotating shaft 310a is fixedly connected to the fourth bevel gear 310d, the other end of the third rotating shaft 310a is fixedly connected to the rotating block 310b, the third bevel gear 310c is meshed with the fourth bevel gear 310d, and a movable groove 310g is provided on the rotating block 310b. One end of the first spring 310f is fixedly connected to the boss 310e, and the other end of the first spring 310f is fixedly connected to the inner wall of the movable groove 310g.

[0032] See also Figure 2 , Figure 4 , Figure 5 , Fig. 9 and Fig.10The conveying assembly 320 includes a chain 320a, a driving roller 320b, a third gear 320c, a sprocket 320d and a fourth gear 320e. The driving roller 320b is rotatably connected to the side wall of the filter tank 301, and the sprocket 320d is fixedly connected to both sides of the driving roller 320b. The sprocket 320d is meshed with the chain 320a. The other end of the third rotating shaft 310a is fixedly connected to the third gear 320c. A driving roller 320b is fixedly connected to the fourth gear 320e, and the third gear 320c is meshed with the fourth gear 320e.

[0033] See also Figure 3 and Fig. 9 The filter assembly 330 includes a filter frame 330a, a filter plate 330b, a second spring 330c and a side plate 330d. The filter frame 330a is fixedly connected to the chain 320a. A buffer groove 330e is provided in the filter frame 330a. The side plate 330d is fixedly connected to both ends of the filter plate 330b. One end of the second spring 330c is fixedly connected to the side plate 330d, and the other end of the second spring 330c is fixedly connected to the inner wall of the buffer groove 330e.

[0034] In this embodiment, when the first screw rod 220a rotates, the third bevel gear 310c and the fourth bevel gear 310d are meshed, so that the third rotating shaft 310a can be rotated to drive the rotating block 310b to rotate. At the same time, the third gear 320c and the fourth gear 320e are meshed, so that the driving roller 320b can drive the sprocket 320d to rotate, so that the chain 320a drives the filter assembly 330 to rotate, and the paint blocks in the water can be discharged into the filter pool 301 through the filter assembly 330, so that the paint blocks can be cleaned up and avoid the paint blocks from accumulating in the filter pool 301 after long-term use; when the rotating block 310b rotates, the boss 310e can be brought into contact with the filter plate 330b, so that the boss 310e knocks on the filter plate 330b, thereby generating vibration, which can make the paint blocks fall out of the filter plate 330. b, so as to prevent some paint blocks from clogging the filter plate 330b and affecting the circulation of water flow. Furthermore, when the boss 310e contacts the filter plate 330b, since the side of the boss 310e that contacts the filter plate 330b is spherical, the boss 310e can be moved into the movable groove 310g on the rotating block 310b, so that the rotating block 310b can continue to rotate, which is convenient for the boss 310e to knock the subsequent filter plate 330b; through the inclined groove 101c, the paint blocks that sink to the bottom of the water can slide into the filter pool 301. By arranging multiple filter components 330 on the chain 320a, it can be prevented that the paint blocks move to the filter box 110c, and the filter holes on the filter box 110c are blocked by paint blocks, resulting in the water supply of the water pump component 110 being affected, which is not conducive to the use of the device.
