Description

Technical Field

[0001] This utility model relates to the field of tennis ball shell sewing technology, and in particular to a tennis ball shell sewing device. Background Technology

[0002] Tennis can be traced back to the 12th century when missionaries in northern France played a game of hitting a ball with their palms in the cloisters of churches. In the 17th century, small square nets and stringed rackets were used. Tennis is a recreational activity, as well as a ball sport with a long history and widespread popularity around the world.

[0003] Currently, traditional tennis ball shell sewing equipment mainly combines the rubber core and the outer felt in a specific way. In the early days, manual sewing was used, employing a chain stitch or stitching the leather edge with needle and thread to ensure that the felt is firmly attached to the core, thus guaranteeing the performance and durability of the tennis ball.

[0004] Current traditional tennis ball shell sewing equipment, while achieving the sewing of the shell, cannot automatically feed and output the product, nor can it automatically adjust multi-angle sewing. Therefore, a tennis ball shell sewing equipment is proposed to solve the above problems. Utility Model Content

The guide 2 is fixedly connected to the top side of the base 1, and the top cover 3 is installed on the top side of the guide 2. The top cover 3 has a placement opening 4 on its top side. An inclined plate 5 is fixedly connected to the right side of the base 1, and a transfer plate 6 is fixedly connected to the right side of the inclined plate 5. A launching frame 12 is fixedly connected to the top side of the 5th plate, a fixed frame 8 is fixedly connected to the top side of the transfer plate 6, a preparatory cylinder 25 is fixedly connected to the top side of the launching frame 12, a dwell cylinder 24 is slidably connected to the inner side of the preparatory cylinder 25, an operating cylinder 13 is slidably connected to the outer side of the dwell cylinder 24, an electric frame 15 is fixedly connected to the top side of the fixed frame 8, a motor 16 is fixedly connected to the inner side of the electric frame 15, the fixed frame 8 supports the electric frame 15 and the motor 16, providing a stable installation foundation for the equipment power system, and the motor 16, as a power source, can provide power for the sewing operation through the relevant transmission structure.

[0034] Reference Figure 3 - Figure 5 The operating cylinder 13 is rotatably connected to a rotating shaft 23. Multiple evenly distributed sliding frames 26 are fixedly connected to the outside of the rotating shaft 23. An anti-detachment plate 27 is fixedly connected to the bottom of the sliding frame 26. A sliding plate 31 is slidably connected to the inside of the sliding frame 26. A support plate 32 is fixedly connected to the top of the sliding plate 31. A sewing assembly is installed on the top of the support plate 32. The sewing assembly includes a sewing frame 28. An air cylinder 29 is fixedly connected to the inside of the sewing frame 28. A sewing head 30 is fixedly connected to the bottom of the sewing frame 28. The evenly distributed design of multiple sliding frames 26 and sewing assembly can realize simultaneous or sequential sewing of different positions on the tennis ball shell. With the flexible adjustment of each structure, the sewing efficiency is greatly improved, and the quality of each sewing part is guaranteed to be consistent, enhancing product uniformity.

[0035] Reference Figure 1 - Figure 4 The inner side of the operating cylinder 13 abuts against the tennis ball 22 to be sewn. The outer side of the tennis ball 22 is rotatably connected to a universal joint 21. The outer side of the universal joint 21 is slidably connected to a fixing ring 20. The outer side of the fixing ring 20 is fixedly connected to a sliding rod 19. The outer side of the sliding rod 19 is slidably connected to a sliding cylinder 18. The outer side of the sliding cylinder 18 is fixedly connected to a drive shaft 17. The inner side of the operating cylinder 13 abuts against the tennis ball 22 to be sewn. With the rotatable connection between the universal joint 21 and the outer side of the tennis ball, it can provide stable support for the tennis ball. At the same time, with the sliding cooperation of the fixing ring 20, the sliding rod 19 and the sliding cylinder 18, the fixing ring 20 can be retracted after sewing is completed, and the tennis ball will automatically fall into the transfer groove 7.

[0036] Reference Figure 2 - Figure 4The universal joint 21 is rotatably connected to the outside of the drive shaft 17. The drive shaft 17 is fixedly connected to the bottom of the gear shaft 14. The drive end of the motor 16 is rotatably connected to the inside of the gear shaft 14. The gear shaft 14 is rotatably connected to the top of the fixed frame 8. The universal joint 21 is rotatably connected to the drive shaft 17. With the drive of the motor 16 and the gear shaft 14, the rotation angle of the tennis ball 22 to be sewn can be flexibly adjusted to ensure that the sewing head 30 can accurately align with each sewing point and improve sewing accuracy.

[0037] Working principle: First, the tennis ball shell is placed into the device through the placement port 4 of the top cover 3. After entering the guide port 2, the tennis ball shell slides into the base 1 along the guide port 2. The tennis ball shell enters the preparation cylinder 25 through the passing tube 11 on the base 1. The tennis ball shell arrives at the holding cylinder 24, waiting for the subsequent sewing operation. The function of the holding cylinder 24 is to temporarily store the tennis ball shell, ensuring that each shell can enter the sewing process at the correct time. The motor 16 starts. The motor 16 is the power source of the device. It drives the speed change shaft 14 and the drive shaft 17 to rotate, providing power for the entire positioning process. The rotation of the drive shaft 17 drives the universal shaft 21 to rotate. The universal shaft 21 can rotate in multiple directions, thereby adjusting the angle of the tennis ball 22 to be sewn. Through the rotation of the universal shaft 21, the tennis ball 22 to be sewn can be accurately positioned, ensuring that the sewing head 30 can accurately sew the tennis ball shell.

[0038] The sewing assembly sews the tennis ball shell. Power is provided by the air compressor 29, which generates thrust through compressed air, driving the sewing head 30 to move. Driven by the air compressor 29, the sewing head 30 sews the tennis ball shell. The design of the sewing head 30 ensures sewing quality and efficiency. The position of the sewing assembly can be adjusted through the cooperation of the sliding rod 19 and the sliding cylinder 18, as well as the sliding of the sliding frame 26, the sliding plate 31, and the support plate 32. After sewing is completed, the sliding rod 19 automatically detaches from the tennis ball, which automatically falls into the transfer groove 7 and exits automatically. The compressor 9 and control key 10 are used to control the operation and parameter settings of the equipment, ensuring normal operation. The compressor 9 can adjust the pressure of the air compressor 29, thereby controlling the sewing force of the sewing head 30. The control key 10 can set the operating parameters of the equipment, such as sewing speed and number of sewing passes, ensuring that the equipment can be adjusted according to different needs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
