[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Example: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a trimming device for processing plastic products, comprising: a base 1; a positioning device 2, the outer wall of which is rotatably connected to the inner wall of the base 1; a servo motor 3, the bottom of which is fixedly connected to the bottom end inside the base 1; a grinding wheel 4, the inner wall of which is fixedly connected to the output end of the servo motor 3; the positioning device 2 includes a rotating shaft 21, a limiting frame 22 is fixedly connected to the outer wall of the rotating shaft 21, a sliding device 23 is slidably connected inside the limiting frame 22, a fixing device 24 is slidably connected to the end of the limiting frame 22 away from the rotating shaft 21, a positioning hole 5 is provided in the wall of the base 1, and the interior of the base 1 is rotatably connected to the outer wall of the rotating shaft 21.

[0019] The sliding device 23 includes a sliding plate 231. A movable rod 232 is slidably connected to the inner wall of the sliding plate 231. A lower pressure plate 234 is fixedly connected to the bottom end of the movable rod 232. A threaded rod 233 is rotatably connected to the inner wall of the lower pressure plate 234. The outer wall of the threaded rod 233 is threadedly connected to the inner wall of the sliding plate 231. The outer wall of the sliding plate 231 is slidably connected to the inner wall of the limiting frame 22. Rotating the threaded rod 233 causes it to move in the up and down direction of the sliding plate 231. During clamping, the threaded rod 233 is controlled to descend. The lower pressure plate 234 is pressed down by the positioning of the movable rod 232, so that the plastic product remains stable. During trimming, the servo motor 3 is started, causing the grinding wheel 4 to rotate and move the limiting frame 22 to the grinding position. The sliding device 23 is controlled to stabilize the plastic product. Then, the sliding device 23 is pushed so that the side of the plastic product passes through the rotating grinding wheel 4 to complete the trimming operation.

[0020] The fixing device 24 includes a pull column 241, a sliding column 241 fixedly connected to the outer wall of the pull column 241, a pin 244 fixedly connected to the end of the pull column 242 away from the pull column 241, a tension spring 243 provided on the outside of the pin 244, a limit plate 245 slidably connected to the outer wall of the pin 244, the outer wall of the limit plate 245 fixedly connected to the inner wall of the limit frame 22, one end of the tension spring 243 fixedly connected to the outer wall of the limit plate 245, and the other end of the tension spring 243 fixedly connected to the outer wall of the sliding column 242. The outer wall of the sliding column 242 slidably connects to the inner wall of the limit frame 22. In use, it is necessary to rotate the rotating shaft 21. When the limiting frame 22 is moved to the appropriate trimming position, the operator pulls out the pulling column 241, causing it to be pulled out of the limiting frame 22. At this time, the sliding column 242 and the pin 244 will move simultaneously with the pulling column 241, and the pin 244 will retract into the limiting frame 22. Simultaneously, the limiting plate 245 and the sliding column 242 will stretch the tension spring 243. Then, the limiting frame 22 is rotated to the appropriate position, and the pulling column 241 is released. The previously stretched tension spring 243 retracts and drives the sliding column 242 to move. Under the positioning action of the sliding column 242, the pin 244 passes through the central hole of the limiting plate 245 and enters the positioning hole 5, completing the fixation.

[0021] Working principle:

[0022] In use, the sliding device 23 of the positioning device 2 assists in the trimming operation. A hard plastic product is placed on top of the base 1 and positioned into the gap between the limiting frame 22 and the base 1. Then, the threaded rod 233 is rotated, causing it to move vertically along the sliding plate 231. During clamping, the threaded rod 233 is lowered, and the lower pressure plate 234 is pressed down by the positioning control of the movable rod 232, keeping the plastic product stable. During trimming, the servo motor 3 is activated, causing the grinding wheel 4 to rotate and moving the limiting frame 22 to the grinding position. The sliding device 23 is used to stabilize the plastic product. Then, the sliding device 23 is pushed so that the side of the plastic product passes through the rotating abrasive wheel 4 to complete the trimming operation. The sliding device 23 ensures the relative stability of the position of the plastic product at the bottom of the limit frame 22, effectively preventing the plastic product from shifting during the trimming process, reducing trimming defects and waste caused by shifting. The stable position of the plastic product helps to improve the efficiency of the trimming operation. The operator does not need to frequently adjust the position of the plastic product and can focus more on the trimming work, thereby speeding up the production speed.

[0023] The positioning device 2 is fixed by a fixing device 24 to fix the position of the limiting frame 22 of the positioning device 2, preventing the limiting frame 22 from being accidentally touched by the operator. During use, the limiting frame 22 on the rotating shaft 21 needs to be rotated to a suitable trimming position. At this time, the operator pulls out the pulling column 241, causing it to be pulled out of the limiting frame 22. The sliding column 242 and the pin 244 will move simultaneously with the pulling column 241, and the pin 244 will retract into the limiting frame 22. Simultaneously, the limiting plate 245 and the sliding column 242 will stretch the tension spring 243. Then, the limiting frame 22 is rotated to a suitable position, and the pulling column 241 is released. The previously stretched tension spring 243 retracts, driving the sliding column 242 to move. Under the positioning action of the sliding column 242, the pin 244... 4. The device passes through the center hole of the limiting plate 245 and enters the positioning hole 5 to complete the fixation. The fixing device 24 prevents damage to the plastic product being trimmed, which helps to ensure the consistency of trimming quality. The stable and fixed limiting frame 22 provides a reliable and standard positioning reference for the plastic product, so that the position and size of each trimming can be kept consistent, thereby improving the product qualification rate and overall quality. Furthermore, it can improve production efficiency, avoid trimming errors caused by accidental touch, reduce the generation of waste products and the time for reprocessing, and make the entire production process smoother and more efficient. In addition, it can reduce the work pressure and psychological burden of operators, so they do not have to worry about the adverse consequences of accidentally touching the limiting frame 22, and can focus more on the trimming operation itself, thereby further improving work quality and efficiency.
