Description

Technical Field

[0001] The utility model relates to the technical field of yarn feeding mechanisms, in particular to a stable yarn feeding mechanism for a circular knitting machine. Background Art

[0002] The stable yarn feeding mechanism ensures that the yarn is fed into the knitting area at a constant speed and tension, which is crucial for maintaining the quality of the knitted fabric. If the tension or speed of the yarn is unstable, it may cause problems such as uneven tightness, broken yarn or loop dropping in the knitted fabric. Components such as the yarn accumulator and yarn loop bracket in the yarn feeding mechanism can adjust the tension of the yarn, avoiding yarn breakage caused by excessive tension or yarn slack caused by too little tension, thus affecting the smooth progress of the knitting process and the quality of the finished product. During the yarn feeding process, the yarn accumulator can store a certain amount of yarn, so that even if the yarn supply is interrupted for a moment, the knitting process can be ensured not to stop immediately, improving the continuity and efficiency of production. The yarn feeding mechanism may also be equipped with a cleaning device to remove impurities or dust that may exist on the yarn, preventing these impurities from damaging the knitting needles or affecting the appearance and feel of the knitted fabric during the knitting process.

[0003] However, during the use of the existing stable yarn feeding mechanism for circular knitting machines, the yarn feeding mechanism is prone to reverse rotation, which may cause the yarn to become entangled, increasing the risk of yarn breakage. And during the use process, it is inconvenient to adjust the tightness state of the yarn, resulting in uneven density of the products knitted from the yarn. Therefore, it is necessary to propose a new stable yarn feeding mechanism for circular knitting machines. Summary of the Utility Model

[0020] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1-4 shown, the present utility model provides a technical solution: a stable yarn feeding mechanism for a circular knitting machine, including a connecting plate 1. Four groups of limiting plates 2 are tightly connected to the top of the connecting plate 1. One side of two of the limiting plates 2 is rotatably connected to a first rotating shaft 6, and one side of the other two limiting plates 2 is rotatably connected to a second rotating shaft 22. One end of the first rotating shaft 6 is provided with a limiting circular block 18. A first clamping block 20 is connected inside the limiting circular block 18. Both sides of the first clamping block 20 are clamped and connected with a second clamping block 19. One side of the second clamping block 19 is tightly connected with a soft pad 17. A fixed shaft 3 is inserted through the middle of one side of the soft pad 17. One end of the fixed shaft 3 is fixedly connected to one side of the limiting plate 2. One side of both the first rotating shaft 6 and the second rotating shaft 22 is inserted with a rotating circular shaft 15. One end of the rotating circular shaft 15 is inserted with a pulley 14. A belt 4 is sleeved on the circumference of the pulley 14. One end of the rotating circular shaft 15 is connected with a rotating motor 5.

[0023] In this embodiment, the load-bearing effect of the overall device can be improved by setting the connecting plate 1. Then, under the action of the limiting plate 2, it is convenient to install subsequent devices. Then, starting the rotating motor 5 can drive the rotating shaft 15 to perform a rotating operation. During the rotation of the rotating shaft 15, the pulley 14 and the belt 4 can be driven to operate synchronously. During the operation of the pulley 14 and the belt 4, the first rotating shaft 6 and the second rotating shaft 22 can be driven to operate. When using the limiting circular block 18, the first clamping block 20 can be installed at one end of the first rotating shaft 6. Then, by using the fixed shaft 3 and the soft pad 17, the second clamping block 19 can be installed on one side of the first clamping block 20 to prevent the first rotating shaft 6 and the second rotating shaft 22 from reversing during the yarn feeding process, resulting in the yarn being caught on the limiting plate 2, which will increase the risk of yarn breakage.

[0024] Embodiment 2: As Figures 1-4 shown, on both sides of the middle of the connecting plate 1, there are fastening connections with the mounting plates 7. Inside one side of the mounting plate 7, there is a fastening connection with the limiting circular shaft 21. Inside the other side of the mounting plate 7, there is a fastening connection with the lead screw 16. The top of the lead screw 16 is connected to the lead screw motor 13. One end of both the lead screw 16 and the limiting circular shaft 21 is inserted and connected with the slider 12. One side of the slider 12 is fastened and connected with the cross plate 11. The top of the cross plate 11 is fastened and connected with the limiting rod 9. The bottom of the limiting rod 9 is fastened and connected with the tensioning device 10.

[0025] In this embodiment, by setting the mounting plate 7, it is convenient to install the lead screw 16 and the limiting circular shaft 21. Then, under the cooperation of the lead screw 16 and the lead screw motor 13, the slider 12 can be driven to perform a lifting operation. During the lifting of the slider 12, the cross plate 11 can be driven to lift synchronously. Then, by using the limiting circular shaft 21, it can be prevented that during the lifting of the slider 12 and the cross plate 11, an offset occurs, resulting in a reduction in the subsequent use effect. The limiting rod 9 can be used to fix the tensioning device 10 and the cross plate 11 together. Then, the yarn is passed through the tensioning device 10, and one end of the yarn is connected to one side of the second rotating shaft 22. By adjusting the height of the cross plate 11, the height of the tensioning device 10 and the yarn can be adjusted synchronously to achieve the tightness of the yarn.

[0026] Working principle of this embodiment: When in use, first install the device at a preset position. Under the action of the connecting plate 1, the load-bearing effect of the overall device can be improved. Then, under the action of the limiting plate 2, it is convenient to install subsequent devices. Then start the rotating motor 5, which can drive the rotating shaft 15 to perform a rotating operation. During the rotation of the rotating shaft 15, the pulley 14 and the belt 4 can be driven to operate synchronously. During the operation of the pulley 14 and the belt 4, the first rotating shaft 6 and the second rotating shaft 22 can be driven to operate. When using the limiting circular block 18, the first clamping block 20 can be installed at one end of the first rotating shaft 6. Then, by using the fixed shaft 3 and the soft pad 17, the second clamping block 19 can be installed on one side of the first clamping block 20 to prevent the first rotating shaft 6 and the second rotating shaft 22 from reversing during the yarn feeding process, resulting in the yarn being caught on the limiting plate 2, which will increase the risk of yarn breakage. The mounting plate 7 is used to facilitate the installation of the lead screw 16 and the limiting shaft 21. Then, under the cooperation of the lead screw 16 and the lead screw motor 13, the slider 12 can be driven to perform a lifting operation. During the lifting of the slider 12, the cross plate 11 can be driven to lift synchronously. Then, the limiting shaft 21 can be used to prevent the slider 12 and the cross plate 11 from shifting during the lifting process, resulting in a reduction in the subsequent use effect. The limiting rod 9 can be used to fix the tensioning device 10 and the cross plate 11 together. Then, pass the yarn through the tensioning device 10 and connect one end of the yarn to one side of the second rotating shaft 22. By adjusting the height of the cross plate 11, the height of the tensioning device 10 and the yarn can be adjusted synchronously to achieve the tightness of the yarn.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
