[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a powder coating device for workpiece surfaces, including a housing 1. A fixing plate 2 is fixedly installed on the inner wall of the housing 1. The guide groove of the fixing plate 2 is located near the surface of the support frame 7 to guide the locating wheel 4 and the first gear 5 located inside the U-shaped groove to move stably. The support frame 7 is slidably installed on the outer side of the fixing plate 2. The support frame 7 is U-shaped and slides against the outer side of the fixing plate 2. A side bevel gear 8 is rotatably installed on the inner wall of the support frame 7. A lower bevel gear 9 is meshed on the outer side of the side bevel gear 8 and is rotatably connected to the lower inner wall of the support frame 7. The side bevel gear 8, the lower bevel gear 9 and the upper bevel gear 10 are all located at... Inside the U-shaped groove of the support frame 7, a rotating wheel 12 is rotatably provided at the bottom end of the support frame 7, and the rotating shaft at the top of the rotating wheel 12 passes through the support frame 7 and is fixedly connected to the bottom end of the lower bevel gear 9. The lower bevel gear 9 is connected to the rotating wheel 12 and rotates synchronously. The rotation of the lower bevel gear 9 drives the rotating wheel 12 to rotate. A fixing post 13 is fixedly provided at the bottom end of the rotating wheel 12. A double-headed screw 14 is rotatably provided inside the fixing post 13, and the threads of the double-headed screw 14 are opposite to each other, so as to control the outer suspension plates 15 to move closer to each other to clamp or move away from each other to release the workpiece. The outer spiral sleeve of the double-headed screw 14 is provided with a suspension plate 15, which is used to suspend the workpiece on it for spraying.

[0023] Specifically, the box 1 has a threaded rod 20 inside, and a sliding plate 18 is spirally sleeved on the outside of the threaded rod 20. The other end of the sliding plate 18 is fixedly equipped with a spraying plate 19, and the spraying plate 19 is in contact with the inner wall of the box 1. The spraying plate 19 is used to spray the workpiece suspended on the suspension plate 15.

[0024] Furthermore, a guide groove 3 is provided inside the fixed plate 2, and a limiting wheel 4 is installed inside the guide groove 3. A first gear 5 is fixedly installed on the outer side of the rotating shaft of the limiting wheel 4, and the rotating shaft of the first gear 5 passes through the support frame 7 and is fixedly connected to the outer side of the side bevel gear 8. The side bevel gear 8 is connected to the first gear 5 to rotate synchronously for automatic drive and control of the movement of the support frame 7. The outer side of the first gear 5 is provided with a toothed plate 6, and the bottom end of the toothed plate 6 is fixedly connected to the inner wall of the fixed plate 2. The movement of the first gear 5 drives the limiting wheel 4 to slide inside the guide groove 3. The first gear 5 moves by meshing on the outer side of the toothed plate 6, and cooperates with the limiting wheel 4 to tighten inside the guide groove of the fixed plate 2. An annular groove is formed between the limiting wheel 4 and the fixed plate 2 to prevent it from falling off, thereby achieving the goal of driving the support frame 7. The frame 7 is movable. A handwheel 16 is fixed at one end of the double-headed screw 14, and the handwheel 16 rotates at the bottom end of the fixed column 13. The rotation of the handwheel 16 drives the double-headed screw 14 to rotate, and the rotation of the double-headed screw 14 drives the suspension plate 15 to move, thereby adjusting the height of the suspension plate 15. The outer meshing teeth of the side bevel gear 8 are provided with an upper bevel gear 10, and the upper bevel gear 10 is rotatably connected to the upper inner wall of the support frame 7. The rotation of the upper bevel gear 10 drives the side bevel gear 8 to rotate, which can control the rotation of the first gear 5 on one side of the side bevel gear 8 and adjust the orientation. A first motor 11 is fixed at the top of the support frame 7, and the output end of the first motor 11 passes through the support frame 7 and is fixedly connected to the upper bevel gear 10. The rotation of the output end of the first motor 11 drives the upper bevel gear 10 to rotate.

[0025] It is worth mentioning that a second motor 21 is fixedly installed at the top of the housing 1, and the output end of the second motor 21 passes through the housing 1 and is fixedly connected to the threaded rod 20. The rotation of the output end of the second motor 21 drives the threaded rod 20 to rotate. A sliding column 17 is fixedly installed on the outside of the housing 1, and a sliding plate 18 slides on the outside of the sliding column 17. The sliding plate 18 is spirally sleeved on the outside of the threaded rod 20. The rotation of the threaded rod 20 drives the sliding plate 18 to slide on the outside of the sliding column 17. The movement of the sliding plate 18 drives the spraying plate 19 to spray powder evenly on the surface of the workpiece.

[0026] The first motor 11, the spray plate 19, and the second motor 21 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, a controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: During use, the operator first adjusts the height of the suspended workpiece according to the requirements. Turning the handwheel 16 rotates the double-ended screw 14, which in turn moves the suspension plate 15, thus adjusting its height. The workpiece is then placed inside the hole in the suspension plate 15. The first motor 11 is then started. The output of the first motor 11 rotates, driving the upper bevel gear 10 to rotate. The upper bevel gear 10 then rotates the side bevel gear 8, which in turn moves the first gear 5 to move outside the gear plate 6. The movement of the first gear 5 then moves the limit wheel 4 to the guide... The side bevel gear 8 rotates while the side bevel gear 8 rotates, which in turn drives the lower bevel gear 9 to rotate. The rotation of the lower bevel gear 9 drives the rotating wheel 12 to rotate. The rotation of the rotating wheel 12 drives the suspension plate 15 inside the fixed column 13 to rotate. The rotation of the suspension plate 15 drives the workpiece to rotate. The second motor 21 is started. The output end of the second motor 21 rotates, which drives the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the sliding plate 18 to slide on the outside of the sliding column 17. The movement of the sliding plate 18 drives the spraying plate 19 to spray powder evenly on the surface of the workpiece. This saves a lot of time and energy for the workers and improves their work efficiency.
