[0010] As a preferred technical solution of the suspended workpiece painting device of this utility model, a baffle is provided on one side of the support plate, a through hole is provided in the middle of the baffle, a threaded groove is provided in the middle of one side wall of the support plate, a threaded post is threadedly connected to the inner side of the threaded groove, the threaded post passes through the through hole, and an extrusion plate is fixed at one end of the threaded post.
[0011] As a preferred technical solution of the suspended workpiece painting device of this utility model, a support ring is fixed on the inner bottom edge of the fixed box. The support ring is located outside the rotating column and below the second gear.
[0012] As a preferred technical solution of the suspended workpiece painting device of this utility model, a limiting ring is fixedly sleeved on the outer wall of the rotating column, and the limiting ring is located below the rotating hole.
[0013] As a preferred technical solution of the suspended workpiece painting device of this utility model, a handle is fixed in the middle of the top surface of the movable frame, and a support column is fixed in the bottom surface of the base plate.
[0014] As a preferred technical solution of the suspended workpiece painting device of this utility model, multiple support columns, limiting grooves and adjusting grooves are provided.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This invention utilizes a lifting plate that moves up and down within the hollow plate on the top surface of the base plate, thereby adjusting the height of the suspension components. Limiting plates, under the tension of springs, insert into different limiting slots on the side wall of the lifting plate, thus fixing the suspension components at different heights. All four suspension components can be moved by grasping the handles to lift the moving frame, disengaging the fixing plate from the adjustment slot on the top surface of the support plate. The moving frame is then moved laterally along the support plate, adjusting the spacing between the four suspension components. By adjusting the height and spacing of the suspension components, workpieces of different sizes can be suspended, offering excellent adjustability. This eliminates the need for custom-made painting equipment based on workpiece dimensions, saving costs and facilitating worker operations.
[0017] This invention allows the workpiece to be suspended by a hook in the suspension assembly. A motor drives a transmission shaft to rotate slowly, which in turn drives a first gear to rotate slowly. The first gear, through a second gear, drives a rotating column to rotate slowly, which in turn drives the hook to rotate slowly. This allows the workpiece to rotate slowly automatically, ensuring that the workpiece surface receives paint evenly and improving the quality of the paint application.
[0018] The lifting plate of this invention has a baffle on one side of the support plate at the top to block the suspension assembly, preventing the suspension assembly from detaching from the outside of the support plate. The baffle has a through hole in the middle, through which a threaded post passes and is threaded into the threaded groove on the side wall of the support plate. The extrusion plate at one end of the threaded post tightly presses against the baffle to fix it in place. By rotating the extrusion plate, the threaded post is moved away from the support plate, so that the extrusion plate is no longer in contact with the baffle. The baffle can then be rotated 90 degrees, allowing the suspension assembly to be removed from the outside of the support plate. This facilitates the adjustment of the number of suspension assemblies and enhances the adjustability. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1
[0029] Please see Figure 1-7 As shown, the present invention provides the following technical solution: a suspended workpiece painting device, including a base plate 1, with a support column 11 fixed on the bottom surface of the base plate 1. Multiple support columns 11, limiting grooves 21 and adjusting grooves 221 are provided. Multiple support columns 11 can stably support the base plate 1 and ensure the stability of the workpiece during the painting process.
[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, specifically, a support plate 22 is fixed to the top of the lifting plate 2 to support the suspension assembly 3. The top surface of the support plate 22 is provided with an adjustment groove 221 for adjusting the spacing of the suspension assembly 3. The suspension assembly 3 is provided on the outside of the support plate 22 for suspending the workpiece for painting. The suspension assembly 3 includes a moving frame 31, a fixed box 32, and a rotating column 33. The moving frame 31 is located outside the support plate 22 and can drive the suspension assembly 3 to move and adjust the spacing. A fixed plate 315 is fixed in the middle of the top surface of the inner side of the moving frame 31 for fixing the suspension assembly 3. The fixed plate 315 is movably inserted into the adjustment groove 221. Inside the support plate 22, a handle 311 is fixed in the middle of the top surface of the movable frame 31 for easy lifting. By grasping the handle 311, the movable frame 31 can be lifted, which will move the fixing plate 315 out of the inner side of the adjustment groove 221. Then the movable frame 31 can move laterally along the support plate 22 to adjust the spacing between the four suspension components 3, so that the hook 331 can suspend workpieces of different sizes. After adjustment, the movable frame 31 can automatically move down under the action of gravity, so that the fixing plate 315 can be inserted into the appropriate adjustment groove 221 to fix the suspension components 3. The structure is simple and easy to use. Example 2
[0031] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, specifically, a hollow plate 12 is fixed to the top edge of the base plate 1 for connecting the lifting plate 2. The lifting plate 2 is movably inserted into the inner side of the hollow plate 12, which can drive the suspension assembly 3 to adjust the height. A connecting groove 121 is provided on the outer wall of one side of the upper end of the hollow plate 12 for the movement of the limiting plate 13. The connecting groove 121 is in communication with the inner side of the hollow plate 12, and the limiting plate 13 is movably inserted into the inner side of the connecting groove 121 to limit the lifting of the lifting plate 2. The limiting plate 13 is connected through the hollow plate 12. The lifting plate 2 has a limiting groove 21 on its side wall, which is used to fix the lifting plate 2 in conjunction with the limiting plate 13. One end of the limiting plate 13 is movably inserted into the limiting groove 21. A fixing bracket 122 is fixed on the outer wall of one side of the upper end of the hollow plate 12 to prevent the limiting plate 13 from falling out of the inner side of the connecting groove 121. The fixing bracket 122 is located outside the limiting plate 13. A connecting hole 123 is provided in the middle of the outer wall of one side of the fixing bracket 122 for the movement of the pull rod 131. 3. A pull rod 131 is fixed to the middle of one side wall of the limiting plate 13, which is connected to the inner side of the fixed frame 122. The pull rod 131 is used to pull the limiting plate 13 to move. The pull rod 131 passes through the connecting hole 123. A spring 132 is movably sleeved on the outer side of one end of the pull rod 131. The spring 132 can ensure that the limiting plate 13 will not move accidentally through elastic tension. One end of the spring 132 is fixed on the side wall of the limiting plate 13, and the other end of the spring 132 is fixed on the inner wall of the fixed frame 122. In this solution, by pulling the pull rod 131, the limiting plate 13 is moved out of the inner side of the limiting groove 21, and the lifting plate 2 can move up and down inside the hollow plate 12, which drives the suspension assembly 3 to move up and down to adjust the height. This allows the hook 331 to suspend workpieces of different sizes, further enhancing adjustability and adaptability. After adjustment, under the tension of the spring 132, the limiting plate 13 is reinserted into the appropriate inner side of the limiting groove 21, which can fix the height of the suspension assembly 3 and ensure stability. Example 3
[0032] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, specifically, a fixed box 32 is fixed to the bottom surface of the fixed plate 315 to accommodate the motor 312, the first gear 314, and other structures. The motor 312 (which is existing technology; its operation and principle can be found in existing bidirectional motors, controlled by an external power source, and therefore not described in detail here) is fixed to the edge of the bottom surface of the fixed plate 315. The motor 312 is located inside the fixed box 32. A drive shaft 313 is fixed to the center of the bottom surface of the motor 312 to drive the first gear 314 to rotate. The first gear 314 is fixed to the lower end of the drive shaft 313, enabling it to drive the second gear 332 to rotate. A rotating hole 321 is provided on the edge of the bottom surface of the fixed box 32 for connecting the rotating column 33. The rotating hole 321 is connected to the inside of the fixed box 32. The rotating column 33 is movably inserted into the inside of the rotating hole 321, allowing the hook 331 to rotate. The rotating column 33 passes through the rotating hole 321, and its top end... A second gear 332 is fixed to drive the rotating column 33 to rotate. The second gear 332 is located inside the fixed box 32 and meshes with the first gear 314. A hook 331 is fixed to the lower end of the rotating column 33 for suspending various workpieces. A support ring 322 is fixed to the bottom edge of the inner side of the fixed box 32 to support the second gear 332. The support ring 322 is located outside the rotating column 33 and below the second gear 332. A limit ring 333 is fixedly sleeved on the outer wall of the rotating column 33 to prevent the second gear 332 from moving upward. The limit ring 333 is located below the rotating hole 321. In this solution, the transmission shaft 313 is driven by the motor 312 to rotate slowly. The transmission shaft 313 can drive the second gear 332 to rotate slowly through the first gear 314. The second gear 332 can drive the hook 331 to rotate slowly through the rotating column 33, thereby making the workpiece rotate slowly to ensure that the workpiece receives paint evenly. Example 4
[0033] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 7As shown, specifically, a baffle 24 is provided on one side of the support plate 22 to block the suspension assembly 3. A through hole 241 is provided in the middle of the baffle 24, allowing the baffle 24 to rotate. A threaded groove 222 is provided in the middle of one side wall of the support plate 22 for the threaded connection of the threaded column 23. The threaded column 23 is threadedly connected to the inside of the threaded groove 222 to fix the extrusion plate 231. The threaded column 23 passes through the through hole 241, and the extrusion plate 231 is fixed at one end of the threaded column 23. The extrusion plate 231 can press the baffle 24 tightly from the side, preventing the baffle 24 from rotating. In this solution, simply rotating the extrusion plate 231 will cause the threaded column 23 to rotate inside the threaded groove 222 and move away from the support plate 22, so that the extrusion plate 231 will no longer press the baffle 24. The baffle 24 can rotate 90 degrees, thereby allowing the suspension assembly 3 to be disassembled from the outside of the support plate 22. This facilitates the factory to adjust the number of suspension assemblies 3 as needed and improves adjustability.
[0034] The working principle and usage process of this utility model:
[0035] In use, depending on the size of different workpieces, pulling the pull rod 131 compresses the spring 132, causing the limiting plate 13 to disengage from the inner side of the limiting groove 21. This moves the lifting plate 2 up and down inside the hollow plate 12, thereby adjusting the height of the suspension assembly 3. The height of the hook 331 from the base plate 1 is adjusted to accommodate different workpiece sizes. After adjustment, under the rebound force of the spring 132, the limiting plate 13 re-inserts into the corresponding limiting groove 21, thus fixing the height of the hook 331. Simultaneously, the moving frame 31 can be lifted by grasping the handle 311, causing the fixing plate 315 to move out of the adjusting groove 221. The handle 311 can be used to control the moving frame 31 to move laterally along the support plate 22, thereby moving the suspension assembly 3 and adjusting the spacing between the four suspension assemblies 3 to adapt to workpieces of different sizes. This ensures that the hook 331 can adapt to workpieces of various sizes. Furthermore, by rotating the extrusion plate 231, the threaded column 23 can be rotated inside the threaded groove 222. The extrusion plate 231 moves away from the support plate 22 and no longer extrudes the baffle 24. The baffle 24 can then be rotated ninety degrees, allowing the suspension assembly 3 to be removed from the support plate 22 by passing over the baffle 24. This makes it easier to adjust the number of suspension assemblies 3 as needed.
[0036] After the workpiece is suspended by the hook 331, the motor 312 is started. The motor 312 drives the transmission shaft 313 to rotate slowly. The transmission shaft 313 drives the first gear 314 to rotate slowly. The first gear 314 drives the second gear 332 to rotate slowly. The second gear 332 drives the rotating column 33 to rotate slowly. The rotating column 33 drives the hook 331 to rotate slowly, so that the workpiece can be rotated slowly to receive the paint spraying, so as to ensure the uniformity and integrity of the paint spraying on the workpiece surface.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
