Description

Technical Field

[0001] The utility model relates to the technical field of basketball liner processing, in particular to a rubber vulcanizing device for basketball liner processing. Background Art

[0002] Vulcanization, also known as cross-linking or aging, is the process of adding cross-linking agents such as vulcanizers and accelerators to rubber to transform linear macromolecules into three-dimensional network structures under certain temperature and pressure conditions. Since sulfur was first used to cross-link natural rubber, it is called vulcanization. Basketball liners are generally made of rubber. In the process of producing basketball liners, vulcanization is an essential step.

[0003] When vulcanizing the inner liner of a basketball, the inner liner needs to be heated by a heating mold. However, the existing vulcanization equipment manually places the inner liner of the basketball in the mold, which may cause accidental touch and burns, posing a risk. To address the above problem, the present application designs a rubber vulcanization equipment for processing inner liner of a basketball. Utility Model Content

Two slide grooves 10 are symmetrically provided at the top of the base 1. The moving block 9 is slidably connected to the slide grooves 10. An inflatable tube 11 is installed near the middle position of the moving block 9. The inflatable tube 11 passes through the moving block 9. A telescopic hose 12 is connected to the inflatable tube 11. The other end of the telescopic hose 12 is fixed to the front plate 6. Two extension blocks 13 are arranged on one end of the moving block 9 close to the gantry 2. The two extension blocks 13 are symmetrically distributed, and the adjacent sides of the two extension blocks 13 are both opposite. Two telescopic rods 14 are fixed, and a first spring 15 is sleeved on the telescopic rod 14. A clamping block 16 is fixed to one end of the inner side of the two telescopic rods 14. One end of the first spring 15 is fixed to the clamping block 16, and the other end of the first spring 15 is fixed to the extension block 13. Two sliding rods 17 and a pulling rod 18 are symmetrically fixed on one side of the clamping block 16 close to the extension block 13. The sliding rod 17 and the pulling rod 18 are both slidably connected to the extension block 13. The pulling rod 18 passes through the extension block 13. Four limiting columns 19 are fixed to the top and bottom of the extension block 13. The four limit columns 19 are evenly distributed, and a pressure plate 20 is slidably connected to the four limit columns 19. The limit columns 19 pass through the pressure plate 20, and a second spring 21 is sleeved on the limit column 19. One end of the second spring 21 is fixed to the bottom end of the pressure plate 20, and the other end of the second spring 21 is fixed to the extension block 13. The pressure plate 20 is rotatably connected to a transmission rod 22 at the outer end, and a connecting block 23 is fixed to the outer end of the pulling rod 18. The two transmission rods 22 on the same side are rotatably connected to the connecting block 23 on the same side, and contact blocks 24 are fixed on both sides of the upper mold 4 and the lower mold 5.

[0023] When the device is in use, in the initial state, the moving block 9 is located at the front plate 6. First, the unvulcanized basketball liner is placed between the two clamping blocks 16, and the inflation tube 11 is inserted into the basketball liner to inflate it. The inflated basketball liner contacts the clamping block 16, and the first spring 15 is compressed. The clamping block 16 clamps and fixes it. The first motor 7 is started to drive the threaded rod 8 to rotate. The moving block 9 threadedly connected to the threaded rod 8 drives the extension block 13 to move along the slide groove 10 toward the gantry 2. At the same time, the telescopic hose 12 is stretched, and the inflation tube 11 is always kept to inflate the basketball liner. Move to just below the upper mold 4, heat the upper mold 4 and the lower mold 5, start the hydraulic cylinder 3, and the output ends of the two hydraulic cylinders 3 respectively drive the upper mold 4 and the lower mold 5 to approach the basketball liner. At the same time, the contact blocks 24 on the upper mold 4 and the lower mold 5 approach the corresponding pressing plates 20. When the contact block 24 contacts the pressing plate 20, it drives the pressing plate 20 to approach the extension block 13. The second spring 2 1 is compressed, the transmission rod 22 drives the connecting block 23 to move outward, the connecting block 23 drives the pulling rod 18 to move outward, the pulling rod 18 drives the clamping block 16 to move outward, the first spring 15 is compressed again, when the upper mold 4 and the lower mold 5 are about to close, the clamping block 16 falls off the basketball liner and moves away from the upper mold 4 and the lower mold 5. When the vulcanization process is completed, the hydraulic cylinder 3 is started to make the upper mold 4 and the lower mold 5 move away from the basketball liner, and at the same time, the contact block 24 drives the pressing plate 20 to approach the extension block 13. Under the action of the second spring 21, the pressing block moves away from the extension block 13, and the transmission rod 22 drives the connecting block 23 to move inward, so that the pulling rod 18 and the clamping block 16 are close to the basketball liner. At the same time, under the action of the first spring 15, the clamping block 16 contacts the basketball liner for clamping and fixing. The first motor 7 is started again to drive the threaded rod 8 to rotate in the opposite direction, and the moving block 9 threadedly connected to the threaded rod 8 drives the extension block 13 and the basketball liner to move toward the front plate 6 to complete the vulcanization process.

[0024] It was found in actual use that the moving block 9 was unstable when moving. In order to solve the above problem, in this embodiment, a rear plate 25 is fixed at the rear end position of the top of the base 1, and two limit rods 26 are symmetrically fixed between the front plate 6 and the rear plate 25. The limit rods 26 pass through the moving block 9, and the moving block 9 is slidably connected to the limit rods 26.

[0025] It is found in actual use that the clamping block 16 may shake when moving. In order to avoid the above problem, in this embodiment, the sliding rod 17 is configured to be cross-shaped.

[0026] In actual use, it was found that the basketball liner was not clamped firmly enough. In order to solve the above problem, in this embodiment, the two clamping blocks 16 are arranged in concentric arc shapes, and the adjacent side of the clamping blocks 16 is provided with anti-slip grooves.

[0027] It was found in actual use that in order to ensure the quality of the basketball liner vulcanization processing product, the basketball liner needs to be kept in an expanded state at all times. In order to achieve the above problem, in this embodiment, a groove 27 is provided at the front end position of the end where the upper mold 4 contacts the lower mold 5, and the inflation tube 11 is adapted to the groove 27.

[0028] It is found in actual use that the device may slide due to external force during operation. In order to avoid the above problem, in this embodiment, a plurality of support legs 28 are fixed to the bottom end of the base 1, and the bottom ends of the support legs 28 are provided with anti-slip grooves.
