[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a powder collection mechanism for powder spraying of aluminum alloy profiles, including a collection device main body 1, and a conveying component 2 and a limiting component 3 are respectively installed on the top surface and inside of the collection device main body 1;

[0024] The limiting component 3 includes a moving block 31, a movable block 32, a fixed column 33, a first telescopic spring 34, a second telescopic spring 35 and a limiting column 36. The bottom surface of the moving block 31 is in contact with the top surface of the movable block 32, and the bottom surface of the movable block 32 is in contact with the top surface of the first telescopic spring 34. The outer surface of the fixed column 33 penetrates through the inner wall of the movable block 32, and the two are rotatably connected. The bottom surface of the limiting column 36 is in contact with the top surface of the second telescopic spring 35. A limiting groove is provided on the outer surface of the limiting column 36, and one end of the movable block 32 is clamped in the inner wall of the limiting groove.

[0025] Adopting the above scheme: With the setting of the moving block 31, when the moving block 31 is moved downward, one end of the movable block 32 can be driven to move synchronously, making the whole of the movable block 32 in an inclined state, and prompting the limit post 36 to break away from the restriction of the movable block 32 under the drive of the second telescopic spring 35. Through the settings of the movable block 32 and the fixed post 33, the mobility of the movable block 32 is used to fix and release the position of the limit post 36. During the movement of the movable block 32, the fixed post 33 can ensure that the central position of the movable block 32 remains unchanged. Through the settings of the first telescopic spring 34 and the second telescopic spring 35, the inertia of itself can be used to restore one end of the movable block 32 and the limit post 36 to their original states, enabling the limit post 36 to smoothly break away from the restriction of the movable block 32.

[0026] As Figures 1 to 2 shown, the collection device body 1 includes a collection frame 11 and a stabilizing plate 12. The bottom surface of the collection frame 11 is in contact with the top surface of the stabilizing plate 12. The top surface of the stabilizing plate 12 is respectively provided with a groove and a chute. One side of the collection frame 11 close to the groove is fixedly connected to the side surface of the limit post 36. The bottom surfaces of the first telescopic spring 34 and the second telescopic spring 35 are both fixedly connected to the inner bottom wall of the groove. Both ends of the fixed post 33 are fixedly connected to the inner wall of the groove. Both sides of the moving block 31 are slidably connected to the inner wall of the groove, and the movable block 32, the first telescopic spring 34, and the second telescopic spring 35 are all located inside the groove.

[0027] Adopting the above scheme: Through the setting of the collection frame 11, the powder after spraying can be collected, reducing resource waste. Through the groove provided on the top surface of the collection frame 11, the moving block 31 is more stable during movement, and the positions of the fixed post 33, the first telescopic spring 34, and the second telescopic spring 35 are fixed.

[0028] As Figures 1 to 2 shown, the conveying assembly 2 includes a moving plate 21 and a conveying pipe 22. The bottom surface of the moving plate 21 is slidably connected to the inner wall of the chute, and the moving plate 21 is fixed above the stabilizing plate 12 by bolts. A conveying fan is installed inside the moving plate 21. One end of the conveying pipe 22 is fixedly connected to the side surface of the moving plate 21. The other end of the conveying pipe 22 penetrates through the inside of the collection frame 11, and a filter screen 221 is fixedly installed inside the conveying pipe 22.

[0029] Adopting the above scheme: Through the setting of the moving plate 21, the mobility of the moving plate 21 can be used to smoothly pass the conveying pipe 22 through and out of the inside of the collection frame 11. Through the setting of the conveying fan, the powder after spraying can be conveyed into the inside of the collection frame 11 through the conveying pipe 22. Through the setting of the filter screen 221, the collected powder can be filtered to a certain extent to prevent some other impurities remaining in the powder from entering the inside of the collection frame 11.

[0030] The working principle and use process of the utility model are as follows: first, the staff starts the conveying fan to smoothly convey the sprayed powder to the interior of the collection frame 11 through the conveying pipe 22. During this process, the filter screen 221 can prevent some impurities remaining in the collected powder from entering the interior of the collection frame 11.

[0031] When the powder collection inside the collecting frame 11 is completed, the movable block 31 is pressed downward. After being subjected to the downward pressure, the movable block 32 begins to move downward at one end driven by the fixed column 33 and the first telescopic spring 34, and gradually tilts itself, so that the other end of the movable block 32 can smoothly escape from the inside of the limiting groove. When the limiting block escapes from the restriction of the movable block 32, it will restore to its original state under the inertia of the second telescopic spring 35, and the collecting frame 11 will be separated from the contact with the stabilizing plate 12, thereby disassembling the collecting frame 11 as a whole. At this point, the overall operation process is completed.
