[0002] With the continuous development of society and the continuous improvement of people's living standards, the application scenarios of powder coating processing are becoming more and more extensive. Powder coating refers to a finishing process that involves applying free-flowing, dry, thermosetting or thermoplastic powder materials to the surface of parts. It is one of the most durable finishing processes for different materials. It is perfectly applicable to metals, plastics and other materials used for custom manufacturing. Since the proportion of powder coating needs to be adjusted during powder coating processing to adapt to different production needs, a quantitative feeding method needs to be set during powder coating processing. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a quantitative feeding device for powder coating processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quantitative feeding device for powder coating processing includes a processing cylinder. Two sets of symmetrically arranged fixed shells are fixedly installed on the upper end of the processing cylinder. An inlet communicating with the interior of each fixed shell is fixedly installed on the upper end of the fixed shell, and an outlet communicating with the interior of each fixed shell is fixedly installed on the lower end of the fixed shell. The lower end of the outlet is located inside the processing cylinder. A rotating roller is rotatably installed between the inner walls on both sides of the inlet. Multiple sets of arc-shaped plates are fixedly installed at equal angles on the surface of the rotating roller. A groove is formed on one side of the interior of each fixed shell. Two sets of symmetrically arranged height adjustment components are installed inside the groove. The working ends of the two sets of height adjustment components are connected to a connecting frame. A rotating shaft is rotatably installed between the inner walls on both sides of the connecting frame. A movable plate is fixedly sleeved on the outer side of the middle position of the rotating shaft. A rotating component for driving the movable plate to rotate is arranged inside the groove. An extrusion ball is fixedly installed at the lower end of the middle position of the connecting frame, and an extrusion component is contacted below the extrusion ball.

[0006] Preferably, the height adjustment assembly includes a hydraulic cylinder fixedly installed inside the groove, an extrusion block slidably installed above the inside of the hydraulic cylinder, a top plate slidably installed in a sealed manner below the inside, a second spring provided between the top plate and the extrusion block, the lower end of the second spring being fixedly connected to the surface of the top plate, and the top end of the extrusion block being fixedly connected to the connecting frame.

[0007] Preferably, an installation block is fixedly installed on the side wall of the fixed shell, and an extrusion plate is slidably connected inside the installation block. A second screw is rotatably connected to the upper end of the extrusion plate. The upper end of the second screw is threadedly connected to the installation block and extends to the outside of the installation block. Connecting pipes are connected to both sides inside the installation block. The end of the connecting pipe away from the installation block is connected to the lower part of the corresponding hydraulic cylinder.

[0008] Preferably, the rotating assembly includes gears fixedly installed at both ends of the rotating shaft, and two sets of racks symmetrically arranged are fixedly installed inside the groove, the racks meshing with the corresponding gears.

[0009] Preferably, the extrusion assembly includes a connecting block fixedly installed on the outer wall of the fixed shell near the groove. Inside the connecting block, a sliding plate is slidably connected to the side near the extrusion ball, and a first push plate is slidably connected to the side away from the extrusion ball. A first spring is provided between the first push plate and the sliding plate. One end of the first spring is fixedly connected to the sliding plate. A first screw is rotatably installed on the end of the first push plate away from the first spring.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. In this application, by setting up a squeezing ball, a sliding plate, a first spring, and a first push plate, the operator can drive the first push plate to slide along the inner wall of the connecting block by rotating the first screw. The sliding of the connecting block will squeeze the first spring, thereby increasing the elastic coefficient of the first spring. This allows the amount of powder coating that rotates the movable plate to be adjusted according to the operator's needs.

[0012] 2. In this application, by setting up the mounting block, extrusion plate and second screw, the operator can rotate the second screw to drive the extrusion plate to move down. The downward movement of the extrusion plate will squeeze the hydraulic oil inside the mounting block, so that the hydraulic oil inside the mounting block enters the hydraulic cylinder through the connecting pipe. At this time, the hydraulic oil inside the hydraulic cylinder will generate a thrust on the top plate, which will cause the top plate to squeeze the second spring, thereby changing the elastic coefficient of the second spring, so that the device can quantitatively adjust the amount of powder coating processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 10A quantitative feeding device for powder coating processing includes a processing cylinder 1. Two sets of fixed shells 2 are fixedly installed on the upper end of the processing cylinder 1 in a symmetrical arrangement. A feed port 3 communicating with the interior of the fixed shell 2 is fixedly installed on the upper end of the fixed shell 2. A discharge port 4 communicating with the interior of the fixed shell 2 is fixedly installed on the lower end of the fixed shell 2. The lower end of the discharge port 4 is located inside the processing cylinder 1.

[0026] A rotating roller 5 is rotatably installed between the inner walls on both sides of the feed inlet 3. Multiple sets of arc-shaped plates 6 are fixedly installed at equal angles on the surface of the rotating roller 5. A groove 7 is opened on one side of the inside of the fixed shell 2. Two sets of hydraulic cylinders 20 are fixedly installed in the groove 7. An extrusion block 19 is slidably installed on the upper part of the hydraulic cylinder 20. A top plate 21 is slidably installed on the lower part of the cylinder. A second spring 22 is provided between the top plate 21 and the extrusion block 19. The lower end of the second spring 22 is fixedly connected to the surface of the top plate 21. The top ends of the two sets of extrusion blocks 19 are fixedly connected to a connecting frame 12. The connecting frame 12 is U-shaped, and a rotating shaft 8 is rotatably installed between the inner walls on both sides above it. A movable plate 9 is fixedly sleeved on the outer side of the middle position of the rotating shaft 8. Gears 10 are fixedly installed on both ends of the rotating shaft 8. Two sets of racks 11 are fixedly installed in the groove 7. The racks 11 are meshed with the corresponding gears 10.

[0027] A compression ball 13 is fixedly installed at the lower end of the middle position of the connecting frame 12. A connecting block 18 is fixedly installed on the outer wall of the fixed shell 2 near the groove 7. A sliding plate 14 is sealed and slidably connected inside the connecting block 18 near the compression ball 13. A first push plate 16 is sealed and slidably connected on the side away from the compression ball 13. A first spring 15 is provided between the first push plate 16 and the sliding plate 14. One end of the first spring 15 is fixedly connected to the sliding plate 14. A first screw 17 is rotatably installed on the end of the first push plate 16 away from the first spring 15. The end of the first screw 17 away from the first push plate 16 is threadedly connected to the connecting block 18 and extends to the outside of the connecting block 18. The end of the sliding plate 14 near the compression ball 13 contacts the lower end surface of the compression ball 13 after sliding through the connecting block 18.

[0028] A mounting block 25 is fixedly installed on the fixed shell 2 above the connecting block 18. An extrusion plate 24 is slidably connected inside the mounting block 25. A second screw 26 is rotatably connected to the upper end of the extrusion plate 24. The upper end of the second screw 26 is threadedly connected to the mounting block 25 and extends to the outside of the mounting block 25. Connecting pipes 23 are connected to both sides inside the mounting block 25. The end of the connecting pipe 23 away from the mounting block 25 is connected to the lower part of the corresponding hydraulic cylinder 20.

[0029] The specific working principle of this utility model is as follows: The powder coating is transported through a pipeline or directly poured into the inside of the feed inlet 3, so that the powder falls onto the surface of the movable plate 9 through the feed inlet 3. At this time, the movable plate 9 will be parallel to the end face of the fixed shell 2, so that a small amount of powder coating cannot fall into the processing cylinder 1 through the discharge port 4 for processing. When the powder coating falls into the inside of the feed inlet 3, it will collide with the arc plate 6 due to gravity. The impact on the arc plate 6 will drive the rotating roller 5 to rotate along the inner wall of the discharge port 4. The rotation of the rotating roller 5 will drive several arc plates 6 to move synchronously, so that the arc plates 6 can evenly spread the powder coating on the upper surface of the movable plate 9, avoiding the problem of uneven force caused by the powder coating accumulating in a certain place on the movable plate 9.

[0030] When powder coating remains on the surface of the movable plate 9, the movable plate 9 transmits pressure to the connecting frame 12 via the rotating shaft 8. The connecting frame 12 then transmits the pressure to the extrusion ball 13. Since the arc surface of the extrusion ball 13 contacts the end face of the slide plate 14, when the pressure of the extrusion ball 13 is low, the slide plate 14 cannot cause the first spring 15 to deform, thus limiting the extrusion ball 13. Consequently, the connecting frame 12 cannot drive the movable plate 9 to fall. Because the rack 11 is fixed inside the groove 7, the gear 10 cannot mesh with the rack 11, thus preventing the movable plate 9 from rotating. When the powder coating on the surface of the movable plate 9 reaches a certain amount, the pressure of the extrusion ball 13 exceeds the force required for the first spring 15 to deform, causing the extrusion ball 13 to push the slide plate 14 along the inner wall of the connecting block 18 from the outside in. When the ball 13 moves downward and contacts the limit, the connecting frame 12 drives the movable plate 9 to move synchronously through the rotating shaft 8. When the movable plate 9 moves downward, the gear 10 meshes with the rack 11. At this time, the gear 10 drives the movable plate 9 to rotate through the rotating shaft 8. The end face of the movable plate 9 and the fixed shell 2 are inclined. The powder coating on the surface of the movable plate 9 falls into the discharge port 4 through the rotation of the movable plate 9, and then falls into the processing cylinder 1 for processing. At the same time, the operator can drive the first push plate 16 to slide along the inner wall of the connecting block 18 by rotating the first screw 17. The sliding of the connecting block 18 will squeeze the first spring 15, thereby increasing the elastic coefficient of the first spring 15. This allows the amount of powder coating that rotates the movable plate 9 to be adjusted according to the needs.

[0031] When the connecting frame 12 moves downward, it drives the two sets of extrusion blocks 19 to move synchronously. At this time, the extrusion blocks 19 will extrude the second spring 22. When there is less powder coating on the surface of the movable plate 9, the pressure generated by the connecting frame 12 cannot cause the second spring 22 to deform. As a result, the second spring 22 will push the extrusion block 19 to reset. The extrusion block 19 will drive the movable plate 9 to reset through the connecting frame 12. At this time, the movable plate 9 will prevent the powder coating from falling into the discharge port 4, thereby realizing the quantitative processing of powder coating. At the same time, the operator can rotate the second screw 26 to drive the extrusion plate 24 to move downward. The downward movement of the extrusion plate 24 will extrude the hydraulic oil inside the mounting block 25, so that the hydraulic oil inside the mounting block 25 enters the hydraulic cylinder 20 through the connecting pipe 23. At this time, the hydraulic oil inside the hydraulic cylinder 20 will generate a thrust on the top plate 21, thereby causing the top plate 21 to extrude the second spring 22, thereby changing the elastic coefficient of the second spring 22, so that the device can quantitatively adjust the amount of powder coating processed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
