Description

Technical Field

[0001] The utility model relates to the technical field of sock production seam technology, and more specifically, it relates to a sock production seam device. Background Art

[0002] In the existing sock production technology, the seam process is a key link, which has a direct impact on the quality, appearance and durability of socks. However, the traditional seam method mainly relies on manual operation, which is not only inefficient but also labor-intensive, easily leading to an increase in production costs and worker fatigue.

[0003] Although some modern sock production devices have begun to adopt mechanized seam technology, the existing mechanical seam devices often have design limitations. For example, the clamping and positioning mechanisms of many devices lack flexibility and cannot adapt to the seam requirements of socks with different materials and thicknesses. This non - adaptability may cause problems such as deformation, damage or insecure seams during the sock seaming process, affecting the quality and appearance of socks.

[0004] Another significant shortcoming is the installation and removal process of the sewing needle. In the existing technology, replacing the sewing needle is usually a cumbersome and time - consuming process, requiring workers to operate with special tools. This not only reduces production efficiency, but also during the frequent replacement of the sewing needle, workers are prone to operation errors, resulting in equipment damage or production accidents.

[0032] Please refer to Figures 1-7, A seam sewing device for sock production, comprising a base 1, on which a seam sewing device is provided. The seam sewing device includes a sewing machine 2, a sewing needle 3, a chain 4, a sliding frame 5, a sprocket 6 and a fixing plate 7. Both the sewing machine 2 and the fixing plate 7 are installed at the top of the base 1. The sewing needle 3 is installed on one side of the sewing machine 2. The chain 4 is movably sleeved outside the sprocket 6, and the sprocket 6 is movably installed on the sliding frame 5. A connecting device is provided on one side of the sewing machine 2. The connecting device includes a push sleeve 8, a tension spring 9, a locking rod 10, a positioning groove 11, a spiral groove 12, a top sleeve 13, a sliding ball 14, a fixing sleeve 15, a sliding groove 16, a sliding rail 17, a rotating sleeve 18, a clamping block 19, a connecting sleeve 20 and a guide rail 21. The push sleeve 8 is movably sleeved outside the connecting sleeve 20. The tension spring 9 is movably sleeved outside the locking rod 10. One end of the locking rod 10 is inserted into the positioning groove 11, and the positioning groove 11 is opened on one side of the rotating sleeve 18. The spiral groove 12 is opened inside the rotating sleeve 18. The top sleeve 13 is movably arranged inside the rotating sleeve 18. The sliding ball 14 is fixedly arranged outside the top sleeve 13, and the sliding ball 14 is slidably arranged in the spiral groove 12. The fixing sleeve 15 is fixedly connected to the sewing machine 2. The sliding groove 16 is opened outside the top sleeve 13. The sliding rail 17 is arranged inside the fixing sleeve 15, and the sliding rail 17 is adapted to the sliding groove 16. Both ends of the rotating sleeve 18 are movably connected to the fixing sleeve 15 and the connecting sleeve 20 respectively. One side of the clamping block 19 is slidably installed in the guide rail 21. An adjusting device is provided on the base 1.

[0033] A motor 22 is provided at the top of the sliding frame 5. A transmission shaft 23 is provided in the sliding frame 5. The transmission shaft 23 is connected to the sprocket 6, and the output end of the motor 22 is connected to the transmission shaft 23.

[0034] A guide frame 24 is provided inside the sliding frame 5, and the chain 4 can be movably located in the guide frame 24.

[0035] A flexible plate 25 is provided on one side of the clamping block 19, and the flexible plate 25 is made of rubber material.

[0036] A limiting plate 26 is provided inside the connecting sleeve 20. A spring 27 is provided on one side of the limiting plate 26, and the other end of the spring 27 is connected to the clamping block 19.

[0037] In this embodiment, when the device is needed to sew the mouth of the sock, first, the motor 22 is synchronously turned on so that the two motors 22 rotate in opposite directions. Then, the motor 22 drives the transmission shaft 23 connected to the output end to rotate, thereby driving the corresponding sprocket 6 to rotate. Then, the sprocket 6 drives the chain 4 sleeved on the outside to move along the guide frame 24 and drives the sprocket 6 arranged on the other side to rotate. Then, the position to be sewn is turned upwards, and the sock is clamped between the two chains 4. The running of the chain 4 drives the clamped sock to move. Then, the sewing machine 2 installed on the base 1 is turned on, and the sewing machine 2 drives the sewing needle 3 to start working, thereby realizing the sewing process of the sock. When the sewing needle 3 needs to be installed, first, the sewing needle 3 is inserted into the middle of the connecting sleeve 20. Then, the push sleeve 8 is pushed upwards so that the push sleeve 8 drives the locking rod 10 to move. Then, one end of the locking rod 10 gradually disengages from the positioning groove 11. At the same time, the push sleeve 8 drives the tension spring 9 sleeved on the outside of the locking rod 10 to stretch. Then, the rotating sleeve 18 is rotated in the corresponding direction. The rotating sleeve 18 drives the spiral groove 12 arranged inside to rotate. At the same time, due to the limitation of the sliding groove 16 and the sliding rail 17 on the top sleeve 13, the sliding ball 14 relatively slides along the spiral groove 12, and then the top sleeve 13 slides along the fixed sleeve 15. Then, the top sleeve 13 pushes the clamping block 19 arranged on one side to move. One side of the clamping block 19 slides along the guide rail 21. At the same time, the clamping block 19 cooperates with the limiting plate 26 to squeeze the spring 27. Due to the inclined structure of the guide rail 21, the clamping block 19 gathers inwards while sliding. Then, the clamping block 19 that gradually gathers inwards stably clamps the sewing needle 3 through the flexible plate 25 arranged on one side. Then, the rotation of the rotating sleeve 18 is stopped, the push sleeve 8 is released, and the tension spring 9 drives the push sleeve 8 and the locking rod 10 to reset, so that the other end of the locking rod 10 is engaged with the corresponding rotating sleeve 18, thereby preventing the unnecessary movement of the rotating sleeve 18, and thus realizing the stable installation of the sewing needle 3.

[0038] Please refer to Figures 1-4 , as an implementation manner of a sock production sewing device for the adjusting device: The adjusting device includes a hydraulic cylinder 28 and a hydraulic rod 29. The hydraulic cylinder 28 is installed at the top end of the base 1, and one end of the hydraulic rod 29 is connected to the output end of the hydraulic cylinder 28, and the other end of the hydraulic rod 29 is connected to the sliding frame 5.

[0039] A sliding groove 30 is provided below the sliding frame 5, and the sliding groove 30 is opened on the base 1.

[0040] Rollers 31 are arranged inside the sliding groove 30, and the rollers 31 are movably installed on one side of the sliding frame 5.

[0041] More specifically, when appropriate clamping and positioning are required according to the thickness of the socks, all hydraulic cylinders 28 are synchronously opened. The hydraulic cylinders 28 push the sliding frame 5 to slide along the sliding groove 30 through the hydraulic rods 29 connected to the output ends. At the same time, the sliding frame 5 drives the rollers 31 arranged on one side to slide along the sliding groove 30, thereby reducing the friction generated by the sliding of the sliding frame 5 and reducing equipment wear. When the clamping and positioning position matches the thickness of the socks, the hydraulic cylinders 28 can be closed.

[0042] In summary, when the overall equipment is in use or operation: when it is necessary to use the equipment to sew the socks, first, the motors 22 are synchronously turned on, so that the two motors 22 rotate in opposite directions. Then, the motors 22 drive the transmission shafts 23 connected to the output ends to rotate, thereby driving the corresponding sprockets 6 to rotate. Then, the sprockets 6 drive the chain 4 sleeved on the outside to move along the guide frame 24 and drive the sprockets 6 arranged on the other side to rotate. Then, the position to be sewn is turned upwards, and the socks are clamped between the two chains 4. The running of the chain 4 drives the clamped socks to move. Then, the sewing machine 2 installed on the base 1 is turned on, and the sewing machine 2 drives the sewing needle 3 to start working, thereby realizing the sewing process of the socks. When it is necessary to install the sewing needle 3, first, the sewing needle 3 is inserted into the middle of the connecting sleeve 20, and then the push sleeve 8 is pushed upwards, so that the push sleeve 8 drives the locking rod 10 to move. Then, one end of the locking rod 10 gradually disengages from the positioning groove 11. At the same time, the push sleeve 8 drives the tension spring 9 sleeved on the outside of the locking rod 10 to stretch. Then, the rotating sleeve 18 is rotated in the corresponding direction. The rotating sleeve 18 drives the spiral groove 12 arranged on the inside to rotate. At the same time, due to the limitation of the top sleeve 13 by the sliding groove 16 and the sliding rail 17, the sliding ball 14 slides relatively along the spiral groove 12, and further, the top sleeve 13 slides along the fixed sleeve 15. Then, the top sleeve 13 pushes the clamping block 19 arranged on one side to move. One side of the clamping block 19 slides along the guide rail 21. At the same time, the clamping block 19 and the limiting plate 26 cooperate to squeeze the spring 27. Due to the inclined structure of the guide rail 21, the clamping block 19 converges inwards while sliding. Then, the clamping block 19 that gradually converges inwards stably clamps the sewing needle 3 through the flexible plate 25 arranged on one side. Then, the rotation of the rotating sleeve 18 is stopped, the push sleeve 8 is released, and the tension spring 9 drives the push sleeve 8 and the locking rod 10 to reset, so that the other end of the locking rod 10 is engaged in the corresponding rotating sleeve 18, thereby preventing unnecessary movement of the rotating sleeve 18, and further realizing the stable installation of the sewing needle 3.

[0043] When it is necessary to perform appropriate clamping and positioning according to the thickness of the socks, all hydraulic cylinders 28 are synchronously opened. The hydraulic cylinders 28 push the sliding frame 5 to slide along the sliding groove 30 through the hydraulic rods 29 connected to the output ends. At the same time, the sliding frame 5 drives the rollers 31 arranged on one side to slide along the sliding groove 30, thereby reducing the friction generated by the sliding of the sliding frame 5 and reducing equipment wear. After the clamping and positioning position matches the thickness of the socks, the hydraulic cylinders 28 can be closed.

[0044] In all the solutions mentioned above, for the connection between two components, welding, bolt and nut connection, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
