For example, the term "on" may also be used in certain circumstances to indicate a dependency or connection. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances. Furthermore, the term "plurality" should mean two or more.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Figure 1-Figure 5 The present invention is described in detail with reference to the embodiments.

[0024] A sporting goods outer cover die-cutting machine includes a workbench 1, with a reel 2 and a reel 3 provided at both ends of the workbench 1, which can respectively unwind and rewind the outer cover. The reel 2 and the reel 3 each include a bracket 14 fixedly arranged at both ends of the table top of the workbench 1, a rotating shaft 16 is rotatably arranged between the brackets 14, a servo motor 15 is provided inside the connecting frame 7 and the outer wall of the bracket 14 through a mounting frame, and a movable block 10 and the rotating shaft 16 are respectively arranged at the output end of the servo motor 15.

[0025] The outer covering materials of sporting balls can be roughly divided into the following categories: rubber, PVC, PU, ZK microfiber, and genuine leather. In the process of producing the outer covering into ball products, the outer covering material needs to be cut into round outer coverings of different sizes. These outer coverings can be wound around the rotating shaft 16 of the unwinding roller 2, and the other end is wound around the rotating shaft 16 of the winding roller 3. By starting the servo motor 15, the rotating shaft 16 is driven to rotate, and the outer covering is automatically unwound and wound, thereby realizing automated operation and saving labor.

[0026] The workbench 1 is provided with an L-shaped support plate 5, a through groove 9 and several annular cutting grooves 4 with diameters ranging from small to large. The through groove 9 and the annular cutting groove 4 are all set through the table top of the workbench 1, and the several annular cutting grooves 4 are interconnected by four cross bars 17. The several annular cutting grooves 4 are enlarged in sequence from small to large, and the movement of the electric vibrating knife 25 is coordinated to realize the adjustment of the cutting diameter, so that the tip of the electric vibrating knife 25 can match the annular cutting groove 4 of appropriate size for cutting, making the cutting more thorough.

[0027] Two electric telescopic rods 6 are fixedly provided on the bottom wall of the L-shaped support plate 5, and a connecting frame 7 and a push plate 8 are fixedly provided at the bottom ends of the two electric telescopic rods 6. A collection box 18 is movably placed under the through slot 9, and the push plate 8 is arranged just above the through slot 9. Starting one of the electric telescopic rods 6 can drive the push plate 8 to move downward, pushing the cut skin into the through slot 9, and then falling from the through slot 9 into the collection box 18 for collection.

[0028] The workbench 1 is also provided with a control panel 19, which is electrically connected to the two electric telescopic rods 6 and the three servo motors 15. Each step and process of the skin cutting can be preset on the control system of the control panel 19, so that the winding roller 3 and the unwinding roller 2 can achieve intermittent winding and unwinding, cut the skin during the winding pause, and push the cut skin into the collection box 18. By controlling the electric telescopic rods 6 and the servo motors 15, intermittent cutting of the skin is achieved.

[0029] Start the electric telescopic rod 6, drive the cutting assembly 12 to move downward, and after contacting the outer skin, start the servo motor 15 to rotate at the same time, drive the electric vibrating knife 25 to rotate and cut the outer skin. After cutting, stop rotating, and then start the electric telescopic rod 6 to move upward, so that the outer skin can continue to be rolled up.

[0030] A movable block 10 is rotatably provided on the bottom wall of the connecting frame 7, and a reciprocating screw rod 11 is rotatably provided on the movable block 10. A circular limiting groove 20 is fixedly provided on the bottom wall of the connecting frame 7, and an L-shaped slide rod 21 is fixedly provided on the side wall of the movable block 10. The top end of the L-shaped slide rod 21 can slide inside the circular limiting groove 20. One end of the reciprocating screw rod 11 passes through the side wall of the movable block 10 and is fixedly provided with an adjusting button 22. The other end of the reciprocating screw rod 11 is fixedly provided with a limiting ring 23, so that the movable seat 24 can move between the limiting ring 23 and the movable block 10.

[0031] When it is necessary to adjust the size of the circular diameter of the cut outer skin according to actual production needs, turn the adjusting knob 22 to drive the reciprocating screw 11 to rotate. Since the outer wall of the reciprocating screw 11 is threadedly connected to the cutting assembly 12, the cutting assembly 12 includes a movable seat 24 threadedly connected to the outer wall of the reciprocating screw 11, and an electric vibrating knife 25 is fixedly provided on the bottom wall of the movable seat 24. The rotation of the reciprocating screw 11 drives the movable seat 24 to move left and right along the reciprocating screw 11, adjusting the distance between it and the movable block 10, which indirectly adjusts the diameter of the cut circular outer skin and the size of the circular outer skin.

[0032] When the electric telescopic rod 6 is started to move downward, the connecting frame 7 is also driven to move downward, so that the electric vibrating knife 25 can move downward and pierce the outer skin and enter the corresponding annular cutting groove 4 for rotary cutting. The electric vibrating knife 25 is a common vibrating cutting knife on the market, which can cut the outer skin accurately and quickly.

[0033] A retractable pressure block 13 is rotatably mounted on the bottom wall of the movable block 10 to secure the outer skin. This retractable pressure block 13 includes an inner slider 26 rotatably mounted on the bottom wall of the movable block 10. An elastic member 27 is fixedly mounted on the bottom wall of the inner slider 26. The bottom end of the elastic member 27 is fixedly mounted on the bottom wall of an outer cylinder 28. Slots 29 are symmetrically mounted on the inner wall of the outer cylinder 28, within which the inner slider 26 can move up and down.

[0034] As the cutting assembly 12 moves downward, the retractable pressure block 13 also moves downward. The bottom wall of the outer cylinder 28 first contacts the upper surface of the outer skin and continues to move downward. The inner slider 26 moves downward along the slide groove 29. At this time, the elastic member 27 is in a compressed state, and the outer cylinder 28 presses and fixes the outer skin. The top wall of the inner slider 26 is rotatably connected to the bottom wall of the movable block 10. For example, they can be rotated together through a rotating shaft, so that when the movable block 10 rotates for cutting, it will not affect the fixation of the retractable pressure block 13 to the outer skin.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
