The bottom end of the shell 9 is provided with a protective shell 8, and both sides of the protective shell 8 are fixedly connected to limit grooves 20. The interior of the protective shell 8 is provided with a clamping structure for facilitating feeding;

[0026] The clamping structure includes an electric push rod 17, a half-page gear 25 and a rack 26. The electric push rod 17 is installed at the top of the protective shell 8, and a limit slider 22 is installed at the bottom of the electric push rod 17. The two sides of the protective shell 8 are movably hinged with a second hinge rod 24, and the bottom end of the second hinge rod 24 is movably hinged with a half-page gear 25. The two sides of the limit slider 22 are movably hinged with a first hinge rod 23. The bottom of the front and rear ends of the base 1 is provided with a limit slot 27. The limit slot 27 is provided with a limit block 28. The limit blocks 28 are fixedly connected to the rack 26, and the bottom end of the rack 26 is fixedly connected to a splint 29.

[0027] A conveyor belt 5 is provided inside the frame 4, and drive rollers 7 are provided on both sides of the conveyor belt 5. A drive motor 6 is installed on the left side of the front end of the frame 4. The drive motor 6 is fixedly connected to the front end of the drive roller 7 through a coupling. A workbench 18 is provided on the right side of the top of the base 1. A support rod 19 is installed at the bottom end of the workbench 18. The first hinge rod 23 and the second hinge rod 24 are movably hinged. The limit block 28 slides left and right inside the limit slot 27. The half-page gear 25 is provided at the top of the limit slot 27. The half-page gear 25 and the limit slot 27 cooperate with each other.

[0028] Specifically, if Figure 1 and Figure 2 As shown, the hydraulic cylinder 16 is started, and the hydraulic cylinder 16 drives the protective shell 8 to descend so that the splint 29 descends to a suitable position. After descending to a suitable position, the electric push rod 17 is started, and the electric push rod 17 drives the limit slider 22 to move so that the first hinge rod 23 and the second hinge rod 24 drive the half-page gear 25 to rotate, so that the rack 26 can drive the splint 29 to move toward the middle to clamp and fix the sleeve. Clamping the sleeve can facilitate moving the sleeve to the top of the workbench 18, thereby improving the efficiency of sleeve feeding.

[0029] Example 2: A servo motor 10 is installed on the left side of the housing 9. The output end of the servo motor 10 is fixedly connected to a threaded rod 11. A threaded sleeve 13 is provided on the outside of the threaded rod 11. The bottom end of the threaded sleeve 13 is fixedly connected to a connecting block 14. The bottom end of the connecting block 14 is fixedly connected to a mounting plate 15. A hydraulic cylinder 16 is installed at the bottom end of the mounting plate 15. The hydraulic cylinder 16 is installed at the top of the protective shell 8. The top end of the threaded sleeve 13 slides left and right inside the limiting slide groove 12.

[0030] Specifically, if Figure 1 and Figure 3 As shown, the servo motor 10 is started, and the servo motor 10 drives the threaded rod 11 to rotate, so that the threaded sleeve 13 outside the threaded rod 11 drives the mounting plate 15 to move left and right through the connecting block 14, thereby facilitating the movement of the sleeve between the clamping plates 29 to the top of the workbench 18. When the threaded sleeve 13 moves left and right, the limiting slide groove 12 will limit the threaded sleeve 13 to prevent the threaded sleeve 13 from flipping over outside the threaded rod 11.

[0031] Example 3: Connecting rods 21 are fixedly connected to both sides of the mounting plate 15. The bottom end of the connecting rod 21 near the middle side is fixedly connected to a limit slider 22. A ball 30 is provided inside the limit slider 22. The limit slider 22 slides up and down inside the limit groove 20, and the ball 30 rolls inside the limit slider 22.

[0032] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, when the hydraulic cylinder 16 drives the protective shell 8 to rise and fall, the limit slider 22 on one side of the connecting rod 21 will slide up and down inside the limit groove 20, thereby improving the stability of the lifting and lowering of the protective shell 8. The ball 30 can reduce the friction between the limit slider 22 and the limit groove 20, making it easier for the limit slider 22 to slide up and down inside the ball 30.

[0033] Working principle: When the utility model is in use, the hydraulic cylinder 16 is started, and the hydraulic cylinder 16 drives the protective shell 8 to descend so that the splint 29 descends to a suitable position. After it descends to a suitable position, the electric push rod 17 is started. When the hydraulic cylinder 16 drives the protective shell 8 to rise and fall, the limit slider 22 on one side of the connecting rod 21 will slide up and down inside the limit groove 20, thereby improving the stability of the lifting of the protective shell 8. The ball 30 can reduce the friction between the limit slider 22 and the limit groove 20, making it convenient for the limit slider 22 to slide up and down inside the ball 30. The electric push rod 17 drives the limit slider 22 to move so that the protective shell 8 A hinged rod 23 and a second hinged rod 24 drive the half-page gear 25 to rotate, so that the rack 26 drives the splint 29 to move toward the middle to clamp and fix the sleeve. After clamping, the servo motor 10 is started, and the servo motor 10 drives the threaded rod 11 to rotate, so that the threaded sleeve 13 outside the threaded rod 11 drives the mounting plate 15 to move left and right through the connecting block 14, thereby facilitating the movement of the sleeve between the splints 29 to the top of the workbench 18. After moving to the top of the workbench 18, the electric push rod 17 is started again to move the splint 29 outward, so that the sleeve can be placed on the top of the workbench 18.
