[0026] The limiting structure includes a first drive motor 4, a limiting plate 7, and a first hydraulic cylinder 9. A mounting bracket 2 is installed at the top of the base 1. The first drive motor 4 is installed at the top inside the mounting bracket 2. A rotating shaft 5 is fixedly connected to the output end of the first drive motor 4. A support plate 6 is fixedly connected to the top of the rotating shaft 5. The first hydraulic cylinder 9 is installed at the top inside the support bracket 3. A mounting plate 8 is installed at the bottom end of the first hydraulic cylinder 9. A rotating block 25 is installed at the middle position of the bottom end of the mounting plate 8. A limiting groove 24 is fixedly connected to the top of the limiting plate 7. A ball bearing 23 is provided at the edge inside the rotating block 25.

[0027] The limiting plate 7 is set at the top of the support plate 6, the rotating block 25 is set inside the limiting groove 24, the limiting groove 24 rotates outside the rotating block 25, and multiple sets of balls 23 are provided, with the balls 23 distributed in a ring at equal intervals at the edge inside the rotating block 25.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the first hydraulic cylinder 9 is activated, which drives the limiting plate 7 to descend and press the limiting plate 7 against the top of the plastic foot to limit the plastic foot and prevent the plastic from shifting when the grinding head 28 trims the plastic foot, thus affecting its use. When it is necessary to trim the other side of the plastic foot, the first drive motor 4 is activated. The first drive motor 4 drives the support plate 6 and the plastic foot to rotate through the rotating shaft 5. When the plastic foot rotates, the limiting plate 7 will drive the limiting groove 24 to rotate outside the rotating block 25.

[0029] A protective shell 19 is installed on the right side of the top of the base 1. A servo motor 20 is installed on the right side of the protective shell 19. A threaded rod 21 is fixedly connected to the output end of the servo motor 20. A threaded sleeve 33 is provided on the outside of the threaded rod 21. Sliding rollers 30 are fixedly connected to the left and right sides of the bottom end of the threaded sleeve 33. A slider 31 is fixedly connected to the top of the threaded sleeve 33. A second hydraulic cylinder 32 is installed on the left side of the top of the slider 31. A fixing frame 17 is installed on the top of the second hydraulic cylinder 32. A second drive motor 26 is installed on the left side of the fixing frame 17. The output end of the drive motor 26 is fixedly connected to the connecting shaft 27. A grinding head 28 is installed on the left side of the connecting shaft 27. A limit rod 16 is fixedly connected to the right side of the top of the slider 31. A guide groove 18 is opened on the right side inside the fixed frame 17. The right side of the fixed frame 17 slides up and down outside the limit rod 16 through the guide groove 18. A storage box 22 is provided on the right side of the mounting frame 2. The threaded rod 21 is movably connected to the inside of the protective shell 19. The sliding roller 30 slides at the bottom of the inside of the protective shell 19. The threaded sleeve 33 and the threaded rod 21 cooperate with each other.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, when the position of the grinding head 28 needs to be adjusted according to the plastic foot, the servo motor 20 is activated. The servo motor 20 drives the threaded rod 21 to rotate, which in turn drives the slider 31 to move left and right through the sliding roller 30. The left and right movement of the slider 31 can drive the grinding head 28 to move and adjust its position. When the grinding head 28 needs to be moved up and down, the second hydraulic cylinder 32 is activated. The second hydraulic cylinder 32 drives the grinding head 28 to move up and down through the fixed frame 17. Adjusting the position of the grinding head 28 can facilitate the trimming of plastic feet of different sizes.

[0031] A connecting frame 10 is installed on the right side of the top of the support frame 3. A water tank 11 is installed on the right side of the top of the connecting frame 10. A water pump 12 is installed at the front end of the water tank 11. A water outlet pipe 14 is fixedly connected to the output end of the water pump 12. A hose 15 is fixedly connected between the water outlet pipes 14. A nozzle 29 is fixedly connected to the left side of the bottom end of the water outlet pipe 14. A water inlet pipe 13 is fixedly connected to the input end of the water pump 12. The rear end of the water inlet pipe 13 passes through the inside of the water tank 11. The nozzle 29 is installed on the left side of the top of the fixed frame 17.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, when trimming the plastic foot, the water pump 12 is started. The water pump 12 draws water into the nozzle 29 through the inlet pipe 13 and the outlet pipe 14, and then sprays it into the grinding head 28 through the nozzle 29 to cool the grinding head 28 and prevent the plastic foot from being damaged due to excessive temperature. The hose 15 allows the nozzle 29 to move with the grinding head 28.

[0033] Working Principle: In use, the first hydraulic cylinder 9 is activated, causing the limiting plate 7 to descend and press against the top of the plastic foot, thus limiting its position. When the position of the grinding head 28 needs to be adjusted according to the plastic foot, the servo motor 20 is activated. The servo motor 20 drives the threaded rod 21 to rotate, which in turn moves the slider 31 left and right via the sliding roller 30. This movement of the slider 31 moves the grinding head 28, adjusting its position. When the grinding head 28 needs to be moved up and down, the second hydraulic cylinder 32 is activated. The second hydraulic cylinder 32 moves the grinding head 28 up and down via the fixing frame 17. Adjusting the position of the grinding head 28 allows for convenient repair of plastic feet of different sizes. After moving to the appropriate position, the second drive motor 26 is activated. The second drive motor 26 drives the grinding head 28 to trim the plastic foot. The water pump 12 is activated, and the water pump 12 draws water into the nozzle 29 through the inlet pipe 13 and the outlet pipe 14. Then, the water is sprayed into the grinding head 28 through the nozzle 29 to cool the grinding head 28 and prevent the plastic foot from being damaged due to overheating. The hose 15 allows the nozzle 29 to move with the grinding head 28. When it is necessary to trim the other side of the plastic foot, the first drive motor 4 is activated. The first drive motor 4 drives the support plate 6 and the plastic foot to rotate through the rotating shaft 5. When the plastic foot rotates, the limiting plate 7 will drive the limiting groove 24 to rotate outside the rotating block 25.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
