DETAILED DESCRIPTION
[0014] like Figures 1 to 5 As shown, a rubber leather cutting device for producing basketballs includes a movable frame 2 with fixed plates 1 at both ends, a slide groove 3 is provided on the movable frame 2, the number of the slide frames 2 is two and they are symmetrically arranged, the ends of the movable frame 2 are fixed by the fixed plates 1, and a movable rod 4 is slidably connected inside the slide groove 3. The movable rod 4 is a cylindrical structure and can roll in the slide groove 3. A fixed shaft 5 is rotatably connected to the movable rod 4, and the movable rod 4 is connected to the fixed shaft 5 through a bearing. A roller 7 connected via a support rod 6 is provided on the fixed shaft 5, and a cutter 8 for cutting the shape of the rubber leather of a basketball is provided on the circumferential surface of the roller 7. The cutter 8 is a structure that needs to cut the shape of the rubber leather, and a pressing device for stretching the rubber leather to both sides is provided on the side of the movable frame 2.
[0015] The pressing device includes four support legs 12 extending downward from the four corners of the movable frame 2, the support legs 12 are fixedly connected to the movable frame 2, and a slidably connected extrusion rod 13 is provided at the bottom of the support leg 12. The connection surface between the extrusion rod 13 and the support leg 12 is an inclined surface. The extrusion rod 13 is moved to both sides by pressing the support leg 12 downward, so that the rubber skin is stretched to facilitate cutting by the cutter 8. A downwardly concave card groove 17 is provided on the cut surface of the extrusion rod 13, and a sliding block 15 extending to the inside of the support leg 12 is provided on the cut surface of the support leg 12. The sliding block 15 The bottom of the extrusion rod 13 is provided with blocks 16 located on both sides of the slot 17, the slot 17 is provided with a spring 18 for resetting the sliding block 15, and the extrusion rod 13 is reset by the spring 18 after losing the pressure of the supporting leg 12. The bottom of the extrusion rod 13 is provided with a pressing block 14 for pressing the rubber skin of the basketball, and the bottom of the pressing block 14 is provided with anti-slip protrusions, and the pressing block 14 is provided with a connecting hole. The two pressing blocks 14 located on the same side are provided with a connecting rod (not shown in the figure), and the connecting rod is also provided with a connecting hole, and the connecting hole is equipped with a fixing bolt for fixing the connecting rod.
[0016] The movable rod 4 is symmetrically provided with limit blocks 9, which are fitted with the inner side of the movable frame 2. The limit blocks 9 are used to fix the roller 7 at the center of the movable frame 2 to prevent it from shaking left and right.
[0017] A rotatably connected extrusion cylinder 11 is provided on one side of the movable rod 4 located outside the movable frame 2. A positioning block 10 is provided on the extrusion cylinder 11. The extrusion cylinder 11 slides on the movable rod 4. During use, the operator moves the roller 7 by holding the extrusion cylinder 11. A rubber anti-slip sleeve is provided on the circumference of the extrusion cylinder 11 for the operator to grasp.
[0018] The side of the positioning block 10 that contacts the movable frame 2 is provided with a rubber pad for increasing friction. The operator squeezes the extrusion cylinder 11 to make the positioning block 10 contact, thereby facilitating the lifting of the movable frame 2 as a whole. The method of use of the present invention is briefly described as follows: During use, the operator holds the extrusion cylinder 11 with both hands and squeezes it inward, thereby lifting the movable frame 2 and placing the movable frame 2 on the entire piece of rubber skin. Then, the extrusion cylinder 11 is pressed downward. At this time, the supporting leg 12 is forced to move downward during the pressing process. Since the connecting surface between the supporting leg 12 and the extrusion rod 13 is an inclined surface, when the supporting leg 12 is pressed downward, the extrusion rod 13 will drive the pressing block 14 to move to both sides. During the movement, the pressing block 14 will stretch the rubber skin to both sides, making the rubber skin under the roller 7 thinner, thereby facilitating cutting. During the pressing process, the movable rod 4 is pushed to move, thereby driving the roller 7 to roll above the rubber skin, and the rubber skin is cut into the shape required for making a basketball by the cutter 8.
