[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0031] Therefore, the following detailed description of the embodiments of the present utility model is not intended to limit the scope of the present utility model claimed, but merely represents some embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] As Figures 1-5 shown, this implementation mode provides a frame spraying device, which includes a spraying chamber 1. Inside the spraying chamber 1, there is a spraying mechanism 2 for spraying the frame, and at the top of the spraying chamber 1, there is a cleaning mechanism 3 for cleaning the frame;

[0035] The powder spraying mechanism 2 includes a hanging hook 201, a powder spraying machine 202, a connecting pipe 203, a corrugated pipe 204, a communicating pipe 205, a powder spraying pipe 206 and a first nozzle 207. The hanging hook 201 is arranged inside the powder spraying chamber 1, the powder spraying machine 202 is arranged outside the powder spraying chamber 1, the connecting pipe 203 is arranged at the output end of the powder spraying machine 202, the corrugated pipe 204 is communicatively arranged at one end of the connecting pipe 203, the communicating pipe 205 is communicatively arranged at one end of the corrugated pipe 204, the powder spraying pipe 206 is communicatively arranged at one end of the communicating pipe 205, the first nozzle 207 is communicatively arranged on the side wall of the powder spraying pipe 206, the number of the first nozzles 207 is several and they are evenly distributed, the communicating pipe 205 penetrates through the side wall of the powder spraying chamber 1 and is slidably connected with the powder spraying chamber 1. When in use, the powder spraying machine 202 is started, so that the powder sequentially passes through the connecting pipe 203, the corrugated pipe 204, the communicating pipe 205 and the powder spraying pipe 206, and then is discharged through the first nozzle 207 to spray the vehicle frame hung on the hanging hook 201. Meanwhile, when the powder spraying pipe 206 moves, the corrugated pipe 204 will stretch, and the phenomenon of pipeline fracture affecting the processing process will not occur.

[0036] Considering that there may be some impurities on the vehicle frame, the cleaning mechanism 3 includes a drain pipe 301, a water inlet pipe 302, a hollow pipe 303 and a second nozzle 304. The drain pipe 301 is arranged at the top of the powder spraying chamber 1, the water inlet pipe 302 is communicatively arranged on the side wall of the drain pipe 301, the hollow pipe 303 is communicatively arranged on the side wall of the water inlet pipe 302, the second nozzles 304 are communicatively arranged at both ends of the drain pipe 301, and the second nozzles 304 are located inside the powder spraying chamber 1. When in use, external water is introduced into the water inlet pipe 302, and the water is discharged through the second nozzles 304, and then the vehicle frame is cleaned. Then the worker dries the water stains and then can carry out powder spraying.

[0037] Considering that the effect of powder spraying on the vehicle frame is weak, a chute 4 is opened on the inner bottom wall of the powder spraying chamber 1. A sliding plate 5 is welded on the outer wall of the powder spraying pipe 206. A bidirectional screw rod 6 is threadedly connected inside the sliding plate 5. The bottom of the sliding plate 5 is located inside the chute 4 and is slidably connected with the chute 4. Both ends of the bidirectional screw rod 6 penetrate through the side wall of the powder spraying chamber 1 and are rotatably connected with the powder spraying chamber 1. By rotating the bidirectional screw rod 6, the powder spraying pipe 206 can be moved, so as to adjust the powder spraying range.

[0038] Considering that it is difficult to rotate the bidirectional screw rod 6, an extension block 7 is welded at the bottom of the powder spraying chamber 1. A rotating rod 8 is rotatably connected inside the extension block 7. A first gear 9 is welded at one end of the rotating rod 8. A second gear 10 is welded at one end of the bidirectional screw rod 6. The first gear 9 meshes with the second gear 10. If the bidirectional screw rod 6 needs to be rotated, by rotating the second gear 10, the second gear 10 can be meshed with the first gear 9, so as to rotate the bidirectional screw rod 6.

[0039] Considering that friction will occur between the first gear 9 and the ground when the first gear 9 rotates, a support block 11 for preventing friction between the first gear 9 and the ground is bolted to the bottom of the powder spraying chamber 1. The number of support blocks 11 is four and they are evenly distributed. During use, the support blocks 11 can create a distance between the powder spraying chamber 1 and the ground, facilitating the rotation of the first gear 9.

[0040] Considering that waste liquid will accumulate inside the powder spraying chamber 1, a liquid discharge hole 12 for facilitating the discharge of waste water is opened at the bottom of the powder spraying chamber 1, and an exhaust hole 13 is opened at the top of the powder spraying chamber 1. When the vehicle frame is being cleaned, waste liquid will be generated, and at this time, the water will be discharged through the liquid discharge hole 12.

[0041] Considering that the powder generated during powder spraying will scatter everywhere, a switch door 14 for improving the internal sealing of the powder spraying chamber 1 is hinged on the side wall of the powder spraying chamber 1. During powder spraying, a large amount of powder will be generated, and at this time, closing the switch door 14 can prevent a large amount of powder from being discharged and inhaled by workers.

[0042] Specifically, when this vehicle frame powder spraying device is in use: Hang the vehicle frame on the hook 201, then close the switch door 14, then connect an external water pipe to the water inlet pipe 302, and then the water will pass through the inside of the drain pipe 301 and the hollow pipe 303, and finally be discharged through the second spray head 304, thereby cleaning the vehicle frame to prevent impurities from adhering to the vehicle frame. After cleaning, the user manually dries the water stains, and then the liquid is discharged through the liquid discharge hole 12. Then start the powder spraying machine 202 to make the powder enter the inside of the connecting pipe 203, the corrugated pipe 204, the communicating pipe 205 and the powder spraying pipe 206 in sequence, and finally be discharged through the first spray head 207, thereby performing powder spraying. At this time, the user can also rotate the first gear 9. The first gear 9 meshes with the second gear 10, which will cause the bidirectional screw rod 6 to rotate, and then move the two powder spraying pipes 206, thereby adjusting the powder spraying range. After powder spraying, open the switch door 14, remove the vehicle frame, and then the next processing can be carried out.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
