Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically a circular knitting machine with adaptive yarn guiding function. Background Technology

[0002] A circular knitting machine is a textile equipment used to produce tubular knitted fabrics. It uses circularly arranged needles that form loops through continuous rotation. It is widely used in clothing, home furnishings, and industrial textiles.

[0003] In existing circular knitting machines, yarn is unwound from bobbins, then guided into the knitting zone by a yarn guide before being knitted. During the unwinding adjustment, the yarn is guided by a guide ring to adjust its position, ensuring it follows a predetermined knitting path. However, during this process, the rotational friction between the bobbin and the output rotor may change, potentially causing some yarns to break due to insufficient tension adjustment. This necessitates stopping the machine and reconnecting the yarn to ensure fabric quality, but this also wastes time and reduces equipment efficiency. Therefore, optimization and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to provide a circular knitting machine with adaptive yarn guiding function to solve the problem mentioned in the background art that the yarn is difficult to adaptively guide during the transmission and guiding process, which easily leads to breakage and affects processing efficiency.

[0025] The adaptive adjustment component includes an adjustment plate 8, which is located at the top of the protective frame 3. A fixed rod 9 is provided on the inner side of the top of the adjustment plate 8, and a movable rod 14 is provided on the outer side of the top of the adjustment plate 8. The adaptive adjustment component is used for adaptive tension adjustment of yarn transmission.

[0026] Specifically, such as Figure 2 As shown, a braiding transmission frame 4 is provided on the inner side of the top of the support frame 1, and a braiding transmission wheel 5 is provided on the outer side of the braiding transmission frame 4. Yarn can be braided by passing through the braiding transmission frame 4 and the braiding transmission wheel 5.

[0027] Specifically, such as Figure 2 As shown, the top of the protective frame 3 is connected to a connecting frame 6, and the top of the connecting frame 6 is connected to a rotating connecting shaft 7. The rotating connection between the rotating connecting shaft 7 and the connecting frame 6 facilitates the output and transmission of the yarn.

[0028] Specifically, such as Figure 3 As shown, the adjusting plate 8 is located on the outside of the rotating connecting shaft 7, and the top of the adjusting plate 8 is connected to the sliding frame 10, which is used to limit the movement position of the moving rod 14.

[0029] Specifically, such as Figure 3 As shown, a guide rod 12 is provided on the inner side of the slide frame 10, and a pressure sensor 11 is installed at one end of the slide frame 10. The guide rod 12 improves the accuracy of the moving position of the moving rod 14, and the pressure sensor 11 facilitates the monitoring of the tension of the yarn transmission and facilitates adaptive automatic adjustment.

[0030] Specifically, such as Figure 3 As shown, the moving rod 14 is connected to the outer top of the guide rod 12, and both ends of the moving rod 14 are provided with ball bearings 15. The bottom end of the moving rod 14 is connected to the telescopic rod 13. The extension and retraction of the telescopic rod 13 controls the sliding of the moving rod 14 inside the slide frame 10. The ball bearings 15 improve the moving efficiency of the moving rod 14.

[0031] The buffer protection assembly includes a rotating shaft 19, which is located at the top inner side of the support frame 1. An inner connecting rod 21 is provided at the top of the rotating shaft 19, and a yarn guide ring 16 is provided on the outer side of the inner connecting rod 21. The buffer protection assembly is used for guiding and protecting the yarn during transmission.

[0032] Specifically, such as Figure 4 As shown, the rotating shaft 19 is connected to the inner top of the braiding transmission frame 4, and a buffer protective member 20 is provided on the outer side of the rotating shaft 19. The buffer protective member 20 is connected between the rotating shaft 19 and the braiding transmission frame 4 to facilitate the buffer adjustment of the vertical position of the rotating shaft 19.

[0033] Specifically, such as Figure 4 As shown, a connecting rod 17 is connected to the inner side of the yarn guide ring 16, and an elastic connector 18 is provided on the outside of the connecting rod 17. The yarn guide ring 16 and the inner connecting rod 21 are not fixedly connected. A buffer protection component 20 is provided at the connection point to improve the buffering effect during yarn transmission.

[0034] In this embodiment: a fixed rod 9 and a movable rod 14 are set to guide and adjust the position of the yarn transmission. Then, according to the tension of the yarn during the transmission process, the movable rod 14 can be adjusted accordingly to improve the tightness of the yarn transmission and enhance the stability of the yarn transmission. When the yarn is guided to the bottom, the inner braiding transmission frame 4 and the yarn guide ring 16 are connected for guidance. The yarn guide ring 16 can be adjusted for protection to keep the yarn transmission in a taut state, which helps to improve the stability of the braided product.

[0035] Specifically, the solution is as follows: During the use of the circular knitting machine, the guide rollers need to be installed on the fixed rod 9 and the moving rod 14 at the top of the adjusting plate 8. Then, the guide rollers guide and transmit the yarn on the external bobbin frame. To avoid uneven tension during transmission affecting the stability of yarn transmission, the tension of the yarn during transmission can be detected by the pressure sensor 11. The signal is then transmitted to the terminal, and the telescopic rod 13 is adjusted for extension and retraction through the terminal. The position of the moving rod 14 is adaptively controlled to alleviate the uneven tension of the yarn during transmission. After the yarn passes through the guide ring 16 and the braiding transmission wheel 5, it is braided. When passing through the guide ring 16, the guide ring 16 and the inner connecting rod 21 are set to be non-fixed. A buffer protection piece 20 is set at the connection to improve the buffering effect during yarn transmission. The inner rotating shaft 19 and the braiding transmission frame 4 are connected by the buffer protection piece 20 to facilitate the up and down adjustment of the rotating shaft 19. This ensures that the yarn is always in a taut state during transmission, thereby improving the quality of the woven products.
