Description

Technical Field

[0001] This utility model relates to the field of football production technology, and more specifically, to a hexagonal leather cutting device for footballs. Background Technology

[0002] Football is one of many ball sports. When making a football, the first step is to press rubber into an elastic inflatable bladder, and then wrap it with leather on the outside. It is usually made of alternating hexagons and pentagons. The hexagonal and pentagonal leather outer layers are cut and trimmed using appropriate molds during the manufacturing process, and then sometimes they are sewn together with thread, and sometimes they are directly glued together.

[0003] Most existing cutting machines require manual removal of the hexagons or pentagons after the leather has been cut, which not only increases the workload of workers but also wastes time.

[0004] A search revealed a Chinese patent, CN218404291U, which discloses a hexagonal leather cutting device for football production. This invention prevents the hexagon from getting stuck in the cutting blade by keeping an auxiliary block attached to it until the first pressure plate is lifted. After cutting, the operator uses a controller to activate two second motors, rolling the fabric downwards towards the second pressure plate. Once below the second pressure plate, the operator uses the controller to activate the first motor above the second pressure plate, causing the second pressure plate to press against the fabric and push the cut hexagon into a collection box. This facilitates further processing, eliminating the need for manual removal of the hexagons, thus reducing workload and saving time.

[0005] However, in actual use, the aforementioned hexagonal leather cutting device requires repeated placement and fixation of the cut and uncut parts of the leather to ensure that the leather remains sufficiently flat during cutting. This process is time-consuming and affects the efficiency of leather cutting and processing. Utility Model Content

[0013] By adopting the above technical solution, the leather can be heated to a certain extent, making the cutting of the leather smoother, and the uncut leather can be flattened with assistance. The cut leather waste can be quickly rolled up, optimizing the leather feeding and unloading operation.

[0014] The technical effects and advantages of this utility model are as follows:

[0028] This application discloses a hexagonal leather cutting device for soccer balls, including an operating table 1. A bracket 2 is fixedly connected to the top of the operating table 1, and a collection box 3 is slidably connected to the bottom of the operating table 1.

An upper template 8 is fixedly connected to the bottom of the hydraulic rods 7. Multiple pressing blocks 9 are fixedly connected to the bottom of the upper template 8. An auxiliary positioning mechanism is provided on the upper surface of the operating table 1. The auxiliary positioning mechanism includes a servo motor 10. The bottom of the servo motor 10 is connected to the operating frame 1. The upper surface of the worktable 1 is fixedly connected to a first rotating rod 11, the output end of the servo motor 10 is fixedly connected to the first rotating rod 11, and the second rotating rod 12 is rotatably connected inside the bracket 2. Two sprockets 13 are fixedly connected to the outer sides of the first rotating rod 11 and the second rotating rod 12. A leather auxiliary inlet and outlet mechanism is set on the outer side of the worktable 1. Two hydraulic rods 7 push the upper template 8 and multiple pressure blocks 9 to the punching holes 6 on the outer side of the lower template 5 to cut the leather, so that the cut leather can fall into the collection box 3 for collection. The servo motor 10 provides power to the first rotating rod 11 and the sprockets 13, so that the first rotating rod 11 drives the sprockets 13 to rotate inside the bracket 2.

[0029] Reference Figure 6 and Figure 8As shown, the inner wall of the bracket 2 is fixedly connected to two guide rails 22. Two drive chains 14 are connected to the outer side of the sprocket 13. Multiple clamping blocks 15 are fixedly connected to the outer side of the drive chains 14. Two guide rods 16 are fixedly connected inside the clamping blocks 15. Springs 17 are sleeved on the outer side of the guide rods 16. A sliding frame 18 is fixedly connected to one side of the spring 17. A clamping arm 19 is rotatably connected to the outer side of the sliding frame 18. Two guide wheels 20 are fixedly connected to one side of the clamping arm 19. An anti-slip plate 21 is fixedly connected to the other side of the clamping arm 19. One side of the guide wheel 20 is slidably connected to the outer side of the guide rail 22. The chain on the outer side of the first rotating rod 11... Wheel 13 drives transmission chain belt 14 to rotate outside the first rotating rod 11 and the second rotating rod 12. Then, the two transmission chain belts 14 drive the outer clamping blocks 15 and clamping arms 19 to move. When the two guide wheels 20 on one side of the clamping arm 19 contact the two ends of the guide slide rail 22, the two clamping arms 19 contact the grooves and protrusions at both ends of the guide slide rail 22 respectively, so that the clamping arms 19 can rotate outside the clamping blocks 15. Then, the middle section of the guide slide rail 22 provides the same support for the two clamping arms 19, so that the clamping arms 19 can clamp and limit the leather sides at the top of the two transmission chain belts 14.

[0030] Reference Figure 3 , Figure 7 and Figure 9 As shown, the leather auxiliary feeding and discharging mechanism includes a limiting frame 23. The bottom of the limiting frame 23 is fixedly connected to the upper surface of the operating table 1. Two transmission rollers 24 are rotatably connected to the inner side of the limiting frame 23. A gear 25 is fixedly connected to one side of the transmission roller 24. A first stepper motor 26 is fixedly connected to the top of the operating table 1. The output end of the first stepper motor 26 is fixedly connected to one end of a transmission roller 24. An electric heating type leather heater 27 is fixedly connected to the inner side of the bracket 2. A second stepper motor 28 is fixedly connected to the outer side of the operating table 1. A collecting roller 29 is fixedly connected to the output end of the second stepper motor 28. When leather is put in, the first stepper motor 26 drives one transmission roller 24 to rotate. Through the meshing transmission of the gear 25, the two transmission rollers 24 rotate in opposite directions, thereby flattening the leather and assisting in transmission. Then, the electric heating type leather heater 27 heats the leather to a certain extent, and one end of the cut leather is inserted into the inside of the collecting roller 29. The second stepper motor 28 drives the collecting roller 29 to roll up the cut leather.

[0031] The working principle of this utility model is as follows: When cutting the leather for a soccer ball, the leather is first passed between two transmission rollers 24. Under the meshing transmission of the first step motor 26 and two gears 25, the two transmission rollers 24 can rotate in the same direction, allowing the leather to be smoothly transported to one side of the support 2. Then, one end of the leather contacts the two transmission chains 14. Afterwards, the servo motor 10 drives the first rotating rod 11 and the second rotating rod 12 to rotate through the corresponding two sprockets 13 meshing with the transmission chains 14. Then, after the clamping blocks 15 on the outer side of the two transmission chains 14 rotate to one side of the guide rail 22, the two guide wheels 20 on one side of the clamping arm 19 will fit against the groove and protrusion at one end of the guide rail 22. The two guide rails 22 are supported by one side of the guide rail 22, allowing the clamping arm 19 to... The outer side of the sliding frame 18 rotates, and then the anti-slip plate 21 on one side of the clamping arm 19 is lifted. After the anti-slip plate 21 is lifted, the edge of the leather will fall onto the surface of the transmission chain belt 14. Then, when the two clamping blocks 15 move out of the protrusion at one end of the two guide rails 22, the middle section of the two guide rails 22 will apply the same force to the two guide wheels 20, so that the guide wheels 20 drive the sliding frame 18 to slide on the outside of the guide rod 16 and squeeze the spring 17, so that the clamping arm 19 drives the anti-slip plate 21 to have a larger contact area with the edge of the leather. Then, under the rotation of the transmission chain belt 14, the leather will move to the bottom of the positioning frame 4. Then, the hydraulic rod 7 drives the upper template 8 and the pressure block 9 to press down, so that the pressure block 9 presses the leather into the corresponding punch hole 6. The leather is cut by the pressure block 9 and the punch hole 6.

[0032] Afterwards, the cut hexagonal leather falls downwards into the collection box 3. The cut leather continues to move under the drive of the transmission chain belt 14. When the cut leather moves to the other side of the bracket 2, the other ends of the two guide rails 22 tilt and guide the two guide wheels 20 on the outside of the two clamping arms 19, so that the two clamping arms 19 release the restriction on the cut leather. Then, one end of the leather is inserted into the slit of the collection roller 29. Finally, the second stepper motor 28 drives the collection roller 29 to roll up the cut leather.
