[0002] In the toy manufacturing industry, PVC material is widely used in the production of various toy parts due to its low cost, strong plasticity, and ease of processing. However, after injection molding and other processes, PVC toy parts often have some defects on their surface, such as burrs, scratches, and injection molding marks, which affect the aesthetics and texture of the toys. Therefore, it is necessary to use polishing equipment to treat their surface to achieve a smooth and shiny effect in order to meet the market's requirements for the appearance quality of toys.

[0003] Currently, the most common PVC toy component polishing equipment on the market includes handheld polishing machines and tabletop polishing machines. These types of polishing equipment have many shortcomings when used: First, after polishing each surface, the toy needs to be repositioned and clamped, making it difficult to quickly change to the surface that needs polishing, resulting in low work efficiency; Second, during the polishing process, the PVC dust generated is easily dispersed in the surrounding air, which can easily lead to workers inhaling it directly, thus posing a significant threat to personal safety.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-5 .

[0018] The PVC toy parts polishing equipment includes: a U-shaped support body 1, with a transverse moving unit on its bottom inner wall, a longitudinal moving unit on the transverse moving unit, and a clamping bracket 9 on the longitudinal moving unit. Clamping cylinders 10 are fixedly installed on the outer walls of both sides of the clamping bracket 9. The output shafts of the two clamping cylinders 10 pass through both sides of the clamping bracket 9 and are slidably connected to both sides of the clamping bracket 9. A connecting frame 11 is fixedly installed on the output shafts of both clamping cylinders 10. A steering shaft 12 is rotatably installed on the side of the two connecting frames 11 that is close to each other. Clamping plates 13 are fixedly installed at the ends of the two steering shafts 12 that are close to each other. By extending the output shaft of the clamping cylinder 10, the PVC toy can be fixed using the clamping plates 13. Then, the clamping bracket 9 can be moved horizontally in the lateral and longitudinal directions by the longitudinal and transverse units, thereby moving the toy horizontally in the lateral and longitudinal directions to achieve the purpose of full polishing. A lifting screw 14 is threaded on the top of the U-shaped carrier 1, and a mounting frame 15 is rotatably installed at its bottom end. A polishing unit is provided on the mounting frame 15. The polishing unit includes a fixed mounting bracket. A polishing motor is installed within a mounting frame 15, and a connecting rod is rotatably mounted at the bottom of the mounting frame 15. The output shaft of the polishing motor is fixedly connected to the top end of the connecting rod, and a polishing disc 16 is fixedly mounted at the bottom end of the connecting rod. The polishing motor drives the polishing disc 16 to rotate at high speed to achieve the polishing work. An adsorption box 17 is provided on one side of the C-shaped support 1, and an adsorption tube 18 is provided on the side of the adsorption box 17 near the C-shaped support 1. Two connecting tubes 19 are fixedly mounted on the top of the C-shaped support 1, and the top ends of the two connecting tubes 19 are fixedly connected to the adsorption tube 18. The bottom of each of the two bellows 20 is fixedly installed with a bellows 20, and the bottom of each bellows 20 is fixedly installed with a suction pipe 21. The bottom of the suction pipe 21 is flared. Connecting arms are fixedly installed on the outer walls of both sides of the mounting frame 15. The two connecting arms are fixedly connected to the two suction pipes 21 respectively on the side that is far away from each other. In this way, when the mounting frame 15 is lowered, the suction pipe 21 can also be lowered synchronously through the action of the bellows 20. This can adapt to the vacuuming operation at different polishing heights. In addition, the bottom of the suction pipe 21 is slightly higher than the polishing plate 16, so it will not collide with the toy.

[0019] The aforementioned transverse moving unit includes a transverse support 2 fixed to the inner wall of the bottom of the U-shaped carrier 1, with a transverse screw 4 rotatably installed inside it. A transverse sliding plate 3 is threaded onto the transverse screw 4. To ensure the stable movement of the transverse sliding plate 3, two transverse sliding rods are fixed inside the transverse support 2. Both transverse sliding rods pass through the transverse sliding plate 3 and are slidably connected to it. The aforementioned longitudinal moving unit includes a longitudinal support 5 fixed to the top of the transverse sliding plate 3. A longitudinal screw 7 is rotatably installed inside the longitudinal support 5, and a longitudinal sliding plate 6 is threaded onto the longitudinal screw 7. To ensure the stable movement of the longitudinal sliding plate 6, two longitudinal sliding rods are fixed inside the longitudinal support 5. Both longitudinal sliding rods pass through the longitudinal sliding plate 6 and are slidably connected to it. A stable connection is formed between the longitudinal sliding plate 6 and the clamping support 9 through an L-shaped folding plate 8.

[0020] In this embodiment, to prevent the transverse screw 4 and the longitudinal screw 7 from easily rotating and to ensure stable toy feeding, a first hand crank is fixedly installed at one end of the transverse screw 4, extending outside the transverse support 2. A first support plate is fixedly installed on the side of the transverse support 2 near the first hand crank, with a first fastening screw threaded onto it. A first arc-shaped damping plate is rotatably installed at the bottom end of the first fastening screw. The inner wall of the first arc-shaped damping plate abuts against the transverse screw 4, and the first arc-shaped damping plate is attached to one side of the outer wall of the transverse support 2. The method ensures that the first arc-shaped damping plate can only move up and down in a straight line. One end of the longitudinal screw 7 extends to the outside of the longitudinal support 5 and is fixedly installed with a second hand crank. A second support plate is fixedly installed on the side of the longitudinal support 5 near the second hand crank, and a second fastening screw is threaded on it. The bottom end of the second fastening screw is rotatably installed with a second arc-shaped damping plate. The inner wall of the second arc-shaped damping plate abuts against the longitudinal screw 7, and the second arc-shaped damping plate is in contact with one side of the outer wall of the longitudinal support 5. By using the contact method, it is ensured that the second arc-shaped damping plate can only move up and down in a straight line.

[0021] In this embodiment, when the polishing disc 16 descends to the specified polishing height, in order to firmly fix it at that height, a positioning folding rod is fixedly installed on one side of the outer wall of the mounting frame 15. The top end of the positioning folding rod extends above the C-shaped support 1 and is slidably connected to the top of the C-shaped support 1. A set screw is threaded on one side of the C-shaped support 1, and the end of the set screw abuts against the positioning folding rod.

[0022] In this embodiment, to further improve the clamping stability of the toy, a fastening bolt is threaded onto the bottom of the clamping bracket 9. A horizontal rod is rotatably mounted on the top of the fastening bolt, and two fastening top rods 24 are slidably mounted on it. The tops of the two fastening top rods 24 extend into the two connecting frames 11 and abut against the corresponding steering shafts 12. The two fastening top rods 24 are slidably connected to the bottom of the two connecting frames 11. Two guide posts are slidably mounted on the bottom of the clamping bracket 9, and the tops of the two guide posts are fixedly connected to the horizontal rod. The screw head at the bottom of the fastening bolt is located inside the L-shaped folding plate 8. The L-shaped folding plate 8 provides sufficient space for the operator to easily screw the screw head at the bottom of the fastening bolt.

[0023] In this embodiment, in order to achieve a stable installation of the adsorption box 17, a mounting back plate is fixedly installed on one side of the U-shaped carrier 1. The adsorption box 17 is fixedly installed on the mounting back plate, and an exhaust fan 22 is fixedly installed on the mounting back plate. The air inlet of the exhaust fan 22 is fixedly connected to the adsorption box 17. An interception net 23 is fixedly installed inside the adsorption box 17. An inspection port is opened on one side of the adsorption box 17, and an inspection door is provided inside the inspection port to facilitate subsequent cleaning and maintenance of the intercepted dust.

[0024] The working principle of the PVC toy parts polishing equipment provided by this utility model is as follows: During polishing, the PVC toy part to be polished is first placed between two clamping plates 13. The clamping cylinders 10 fixedly installed on the outer walls of both sides of the clamping bracket 9 are activated. The output shaft of the clamping cylinder 10 pushes the connecting frame 11 to move closer to the toy part until the two clamping plates 13 are tightly attached to the surface of the toy part, thus initially completing the lateral clamping and fixing of the toy part. Subsequently, the fastening bolt is rotated, which pushes the horizontal rod to move upward along the guide post. The horizontal rod drives the two fastening top rods 24 to rise synchronously, so that the top of the fastening top rod 24 abuts against the steering shaft 12 in the connecting frame 11, restricting the rotation of the steering shaft 12, thereby ensuring that the clamping plate 13 holds the toy parts stably and preventing the toy parts from shifting during the polishing process. Then, start the polishing motor, whose output shaft drives the polishing disc 16 to rotate at high speed. At the same time, start the exhaust fan 22, and the two suction pipes 21 form a suction force. Then, turn the lifting screw 14 clockwise, and the mounting frame 15 lowers with the polishing disc 16 and suction pipes 21 until the polishing disc 16 contacts the surface of the toy to be polished. Tighten the set screw, and the polishing disc 16 will then perform the polishing work on the surface of the toy. Then, the transverse screw 4 is rotated at a constant speed, and the transverse slide 3 moves the toy horizontally, so that the polishing disc 16 forms a transverse polishing feed on the surface of the toy. When the feed reaches the edge position, the longitudinal screw 7 is rotated at a constant speed, so that the polishing disc 16 forms a longitudinal polishing feed on the surface of the toy. Then, by alternating the rotation of the transverse screw 4 and the longitudinal screw 7, until one side of the toy is completely polished. During the operation, the first arc-shaped damping plate and the second arc-shaped damping plate provide greater resistance, so that the transverse screw 4 and the longitudinal screw 7 will not rotate easily, ensuring the stability of the feeding process. After polishing one side, first turn the lifting screw 14 counterclockwise to bring the polishing pad 16 back to the high position. Then, tighten the fastening bolt to separate the fastening rod 24 from the steering shaft 12. Then rotate the toy to rotate the other side that needs to be polished to below the polishing pad 16. After that, tighten the fastening bolt again to make the fastening rod 24 contact the steering shaft 12 again. Then turn the lifting screw 14 clockwise to bring the polishing pad 16 down to contact the toy surface again. You can then polish by following the same operation as above. Then, follow the same steps as above to turn the toy over until it is completely polished. During the polishing process, the suction pipe 21 can absorb the generated PVC dust. This air containing a large amount of PVC powder enters the adsorption box 17 through the corrugated pipe 20, connecting pipe 19, and adsorption pipe 18. After being filtered by the interception net 23, it is discharged by the exhaust fan 22. After long-term use, the maintenance door can be opened to centrally process the dust in the adsorption box 17.

[0025] Compared with related technologies, the PVC toy parts polishing equipment provided by this utility model has the following beneficial effects: I. This utility model uses a clamping cylinder 10 to initially clamp the toy, and then uses a fastening top rod 24 to abut against the steering shaft 12 to form a secondary fixation, thus doubly ensuring that the toy parts do not shift during the polishing process and improving the polishing accuracy. Second, this utility model precisely adjusts the polishing height through the lifting screw 14, and achieves alternating feeding with the horizontal screw 4 and the vertical screw 7 to meet the needs of polishing one side of the toy; and when changing sides, there is no need to disassemble the toy, only to loosen the fastening top rod 24 and rotate the toy, which greatly saves the time of changing sides and improves work efficiency. Third, this utility model can expand the dust collection range by using the exhaust fan 22 in conjunction with the trumpet-shaped suction pipe 21, and the interception net 23 in the adsorption box 17 can effectively filter dust and prevent dust from spreading and harming the health of workers.
