Description

Technical Field

[0001] This utility model relates to the field of knitted sock production technology, and in particular to a knitted sock cuff sewing machine. Background Technology

[0002] The sock cuff sewing machine is an automated equipment specifically designed for the final process of sock production. It is a specialized industrial sewing machine used to complete the closure and sewing of sock toes. It adopts a looper hook mechanism and uses a rotary or reciprocating hook needle in conjunction with a sewing element to achieve a circular stitching of elastic knitted fabric.

[0003] The equipment is typically equipped with a photoelectric positioning system and a tension adjustment device to ensure that the stitches are uniform and do not fray. It is suitable for processing socks made of materials such as cotton, nylon, and wool, and is a key piece of equipment for achieving efficient sealing in sock production lines.

[0004] Based on the aforementioned technologies, the applicant believes that existing sock cuff sewing machines lack a pressing and fixing mechanism for knitted socks during use. When sewing the sock cuff, the knitted sock may move due to shaking or other reasons, resulting in sewing failure. To address the above problems, we have introduced a knitted sock cuff sewing machine. Utility Model Content

[0005] This utility model discloses a knitted sock cuff sewing machine, which aims to solve the technical problem that existing sock cuff sewing machines lack a pressing and fixing mechanism for the knitted socks during use, and may cause the knitted socks to move due to shaking or other reasons during the sewing process, resulting in sewing failure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A knitting sock cuff sewing machine includes an operating table. Support frames are symmetrically fixedly connected to the bottom of the operating table. An L-shaped fixing plate is fixedly connected to one side of the top of the operating table. A cylinder is fixedly connected to the top of the L-shaped fixing plate. The telescopic end of the cylinder extends below the L-shaped fixing plate and is fixedly connected to a sewing assembly. A positioning mechanism is provided on the top of the operating table. The positioning mechanism includes a first fixing component, a second fixing component, and a support component. The first fixing component, the second fixing component, and the support component cooperate with each other. The first fixing component includes a mounting plate, which is fixedly connected to one side of the top of the operating table. The mounting plate is close to the L-shaped fixing plate. A mounting bracket is symmetrically fixedly connected to one side of the mounting plate. Two mounting brackets are symmetrically rotatably connected to each other on their sides. Rotating plates are fixedly connected to the outer sides of both rotating shafts. A fixed shaft is fixedly connected between the two rotating plates. A pressing bracket is fixedly connected between the two rotating shafts. A fixed frame is fixedly connected to the side of the mounting plate away from the L-shaped fixed plate. A motor is fixedly connected to the outer side of the fixed frame. The output end of the motor extends to the side of the mounting plate near the L-shaped fixed plate and is fixedly connected to an adjusting plate. An adjusting rod is fixedly connected to the outer side of the adjusting plate. A sliding sleeve is slidably connected to the outer side of the fixed shaft. The sliding sleeve and the adjusting rod are rotatably connected.

[0008] The positioning mechanism allows for quick sewing of the sock cuffs. Before sewing, the knitted socks are pressed and fixed to prevent displacement during the sewing process, which could lead to failed seams. This improves the product's pass rate. The structure is simple and highly practical.

[0009] In a preferred embodiment, the second fixing component includes a sliding column, which is slidably connected to the outside of the telescopic end of the cylinder. A limiting plate is fixedly connected to the top of the sliding column, and a pressing spring is sleeved on the telescopic end of the cylinder above the limiting plate. A connecting frame is fixedly connected to the outside of the sliding column, and a pressing plate is fixedly connected to the bottom of the connecting frame.

[0010] Through the cooperation of sliding column, limiting plate, pressing spring, connecting frame and pressing plate, the second fixing component has an elastic pressing function, which can not only firmly fix the sock cuff, but also avoid excessive compression that could cause fabric deformation, thus adapting to the processing needs of knitted socks of different thicknesses.

[0011] In a preferred embodiment, the support assembly includes a support plate fixedly connected to the top of the operating table. A positioning groove is provided on one side of the top of the support plate, and a fixing groove is provided on the other side of the top of the support plate. The positioning groove and the pressing plate cooperate with each other, and the fixing groove and the pressing frame cooperate with each other.

[0012] The support component, through the design of the support plate, positioning groove and fixing groove, forms a linkage positioning structure with the pressing plate and pressing frame to ensure that the sock cuff remains flat during the sewing process, avoids wrinkles or deviation, and improves the uniformity of the seam.

[0013] In a preferred embodiment, a protective cover is fixedly connected to the outside of the motor, and heat dissipation slots are equidistantly provided on the outside of the protective cover.

[0014] A protective cover and heat dissipation slots are added to the outside of the motor to effectively prevent foreign objects from entering the motor, while optimizing heat dissipation performance, extending the service life of the motor, and ensuring the stable operation of the equipment for a long time.

[0015] In a preferred embodiment, a controller is fixedly connected to one side of the top of the control panel.

[0016] The cylinder, seam assembly, and motor are centrally controlled by a controller to achieve automated operation.

[0017] In a preferred embodiment, the cylinder, the seam assembly, and the motor are all electrically connected to the controller.

[0018] The cylinder, sewing assembly, and motor are all electrically connected to the controller to improve production efficiency, reduce manual intervention, and ensure the consistency and reliability of the sewing process.

[0019] The knitting sock cuff sewing machine provided by this utility model has the following advantages:

[0020] Firstly, the positioning mechanism allows for quick sewing of the sock cuffs. Before sewing, the knitted socks are pressed and fixed to prevent displacement during the sewing process, which could lead to failed seams and improve the product's pass rate. The structure is simple and highly practical.

[0021] Secondly, a protective cover and heat dissipation groove are added to the outside of the motor to effectively prevent foreign objects from entering the motor. At the same time, the heat dissipation performance is optimized, the service life of the motor is extended, and the equipment is guaranteed to operate stably for a long time. The cylinder, sewing assembly and motor are centrally controlled by the controller to realize automated operation, improve production efficiency, reduce manual intervention, and ensure the consistency and reliability of the sewing process.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] The present invention discloses a knitted sock cuff sewing machine, which is mainly used in the production of knitted socks.

[0031] Reference Figures 1-6A knitting sock cuff sewing machine includes an operating table 1. Support frames 2 are symmetrically fixedly connected to the bottom of the operating table 1. An L-shaped fixing plate 3 is fixedly connected to one side of the top of the operating table 1. A cylinder 4 is fixedly connected to the top of the L-shaped fixing plate 3. The telescopic end of the cylinder 4 extends to the bottom of the L-shaped fixing plate 3 and is fixedly connected to a sewing assembly 5. A positioning mechanism is provided on the top of the operating table 1. The positioning mechanism includes a first fixing component, a second fixing component, and a support component. The first fixing component, the second fixing component, and the support component work together. The first fixing component includes a mounting plate 61, which is fixedly connected to one side of the top of the operating table 1. Mounting brackets 62 are symmetrically fixedly connected to the side of the mounting plate 61 closest to the L-shaped fixing plate 3. Two mounting brackets 62 are symmetrically rotatably connected to rotating shafts 63 on their sides close to each other. Rotating plates 64 are fixedly connected to the outer sides of both rotating shafts 63. A fixed shaft 65 is fixedly connected between the two rotating plates 64. A pressing bracket 66 is fixedly connected between the two rotating shafts 63. A fixed bracket 67 is fixedly connected to the side of the mounting plate 61 away from the L-shaped fixed plate 3. A motor 68 is fixedly connected to the outer side of the fixed bracket 67. The output end of the motor 68 extends to the side of the mounting plate 61 close to the L-shaped fixed plate 3 and is fixedly connected to an adjusting plate 69. An adjusting rod 610 is fixedly connected to the outer side of the adjusting plate 69. A sliding sleeve 611 is slidably connected to the outer side of the fixed shaft 65. The sliding sleeve 611 and the adjusting rod 610 are rotatably connected. The second fixing component includes a sliding column 7, which is slidably connected to the outside of the telescopic end of the cylinder 4. A limiting plate 8 is fixedly connected to the top of the sliding column 7. A pressing spring 9 is sleeved on the telescopic end of the cylinder 4 above the limiting plate 8. A connecting frame 10 is fixedly connected to the outside of the sliding column 7, and a pressing plate 11 is fixedly connected to the bottom of the connecting frame 10. The supporting component includes a supporting plate 12, which is fixedly connected to the top of the operating table 1. A positioning groove 13 is opened on one side of the top of the supporting plate 12, and a fixing groove 14 is opened on the other side of the top of the supporting plate 12. The positioning groove 13 and the pressing plate 11 cooperate with each other, and the fixing groove 14 and the pressing frame 66 cooperate with each other.

[0032] In this embodiment: During operation, the cuff of the knitted sock is placed on the positioning groove 13 and fixing groove 14 of the support plate 12. The motor 68 is started to drive the adjusting plate 69 to rotate. The rotation of the adjusting plate 69 causes the sliding sleeve 611 to slide outside the fixing shaft 65. The adjusting rod 610 and the sliding sleeve 611 are linked to rotate the shaft 63, causing the pressing frame 66 to rotate and press down to fix one end of the knitted sock. At the same time, the cylinder 4 drives the seam assembly 5 to move down. Under the action of the pressing spring 9, the sliding column 7 presses the pressing plate 11 to press the other side of the sock cuff, ensuring that the sock cuff is flat and positioned. Through the positioning mechanism, the sock cuff can be quickly sewn. Before sewing, the knitted sock is pressed and fixed to avoid displacement of the knitted sock during the sewing process, which would lead to failure of the knitted sock seam. This improves the product qualification rate. The structure is simple and highly practical.

[0033] In the above technical solution, considering that existing sock cuff sewing machines lack a pressing and fixing mechanism for the knitted socks, the socks may move due to shaking or other reasons during sewing, resulting in sewing failure, the specific operation is as follows:

[0034] Reference Figures 1-6 In a preferred embodiment, a protective cover 15 is fixedly connected to the outer side of the motor 68, and heat dissipation grooves 16 are equidistantly provided on the outer side of the protective cover 15. A controller 17 is fixedly connected to one side of the top of the operating table 1. The cylinder 4, the seam assembly 5, and the motor 68 are all electrically connected to the controller 17.

[0035] In this embodiment, a protective cover 15 and a heat dissipation groove 16 are added to the outside of the motor 68 to effectively prevent foreign objects from entering the motor. At the same time, the heat dissipation performance is optimized, the service life of the motor is extended, and the equipment is guaranteed to operate stably for a long time. The cylinder 4, the sewing assembly 5 and the motor 68 are centrally controlled by the controller 17 to realize automated operation, improve production efficiency, reduce manual intervention, and ensure the consistency and reliability of the sewing process.

[0036] Working principle: During operation, the cuff of the knitted sock is placed on the positioning groove 13 and fixing groove 14 of the support plate 12. The motor 68 is started to drive the adjusting plate 69 to rotate. The rotation of the adjusting plate 69 causes the sliding sleeve 611 to slide outside the fixed shaft 65. Through the linkage between the adjusting rod 610 and the sliding sleeve 611, the shaft 63 is rotated, causing the pressing frame 66 to rotate and press down to fix one end of the knitted sock. At the same time, the cylinder 4 drives the seam assembly 5 to move down. Under the action of the pressing spring 9, the sliding column 7 makes the pressing plate 11 press the other side of the sock cuff, ensuring that the sock cuff is flat and positioned. Subsequently, the seam assembly 5 performs high-speed sewing to complete the sock cuff closure. The entire process is coordinated by the controller 17 to achieve efficient and precise automated sewing, effectively avoiding sock cuff displacement or poor sewing problems.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
