A hosiery machine thread guide

Abstract

This utility model discloses a yarn guiding device for a cotton sock machine, including a first yarn guiding wheel and a second yarn guiding wheel. A limiting wheel for elastically clamping the yarn is provided below the first yarn guiding wheel. Both the first and second yarn guiding wheels are installed inside a frame via a fixed mounting bracket. The two ends of the first and second yarn guiding wheels are rotatably connected to the fixed mounting bracket via bearings. This utility model restricts the rotation direction of the first yarn guiding wheel through a reverse anti-reverse component. The first yarn guiding wheel, in conjunction with the limiting wheel, elastically clamps the yarn. When the yarn breaks, the yarn retracts due to tension, while the first yarn guiding wheel and the limiting wheel clamp the yarn. At the same time, the reverse anti-reverse component locks the first yarn guiding wheel to prevent reverse rotation, thus preventing the yarn from slipping out of the clamping of the first yarn guiding wheel and the limiting wheel. This effectively prevents entanglement caused by yarn breakage during the yarn guiding process and facilitates quick yarn splicing.

Description

Technical Field

[0001] This utility model relates to the field of spinning technology, specifically to a yarn guiding device for a cotton sock machine. Background Technology

[0002] A spinning machine twists together many plant and animal fibers to form threads or yarns, which can then be woven into cloth. The earliest spinning machines were very simple in structure and were first used in the 14th century. After the 18th century, people invented better spinning machines, which made textiles the largest industry. All spinning machines do only two things: first, they gather a large number of short fibers into loose cotton threads, and then they gradually pull out the cotton threads and twist them into finer threads. The twisting process lengthens the cotton threads.

[0003] In the prior art, Chinese utility model publication number CN221192523U discloses a multifunctional high-speed cotton sock machine yarn guiding device, including a mounting plate. A yarn guiding assembly is disposed on the front side of the mounting plate, a fixing plate is fixedly disposed on the top of the mounting plate, a vertically moving assembly is disposed on the surface of the fixing plate, a connecting shaft is disposed on the front side of the mounting plate via the vertically moving assembly, a tension wheel is fixedly disposed on the surface of the connecting shaft, an elastic assembly is disposed on the front side of the mounting plate, and a rotating shaft is disposed on the front side of the mounting plate via the elastic assembly. The rebound action of the elastic assembly pushes the rotating shaft to reset, causing the rotating shaft and the limiting and correcting wheels to push the yarn to reset. The two limiting and correcting wheels limit the yarn, facilitating the provision of appropriate tension for the yarn used in the multifunctional high-speed cotton sock machine. This avoids the situation where the yarn easily breaks when the tension is too high, and avoids the situation where the yarn production quality is affected when the tension is too low. It also facilitates the limiting and correcting of the yarn.

[0004] The above technical solution reduces the quality of yarn production by adjusting the tension of the yarn. However, the yarn guiding device lacks a structure to restrict the yarn after it breaks. This can easily cause the taut yarn to contract rapidly at both ends due to tension at the moment of breakage, making it easy for other yarns to entangle during the yarn contraction process. Utility Model Content

[0005] The purpose of this invention is to provide a yarn guiding device for a cotton sock machine.

[0006] The technical problem solved by this utility model is to restrict broken yarns and prevent them from tangling due to elastic retraction.

[0007] This utility model can be achieved through the following technical solutions:

[0008] A yarn guiding device for a cotton sock machine includes a first yarn guiding wheel and a second yarn guiding wheel. A limiting wheel for elastically clamping the yarn is provided below the first yarn guiding wheel. Both the first and second yarn guiding wheels are mounted inside a frame via a fixed mounting bracket. The two ends of the first and second yarn guiding wheels are rotatably connected to the fixed mounting bracket via bearings. An anti-reverse component is provided on the outer side of the first yarn guiding wheel to prevent the first and second yarn guiding wheels from rotating in reverse. Teeth are fixedly arranged around one end of the arc-shaped surface of the first yarn guiding wheel. The arc-shaped surface of the limiting wheel is provided with a toothed groove that cooperates with the teeth, ensuring that the first yarn guiding wheel and the limiting wheel rotate synchronously in opposite directions to directionally transport the yarn.

[0009] It also includes a tensioning wheel located between the first guide wheel and the second guide wheel. Both the tensioning wheel and the limiting wheel are installed inside the frame via a movable mounting bracket. The two ends of the tensioning wheel and the limiting wheel are rotatably connected to the movable mounting bracket via bearings.

[0010] A further technical improvement of this utility model is that the anti-reverse assembly includes a ratchet fixed to one end of the first guide wheel, a pawl engaged above the ratchet, and the end of the pawl away from the ratchet is rotatably connected to the fixed mounting bracket.

[0011] A further technical improvement of this utility model is that: a fixed box is fixed to the bottom of the inner cavity of the frame by a mounting frame, a support spring is fixed to the bottom of the inner cavity of the fixed box, a connecting frame is fixed to the top of the support spring, the lower end of the connecting frame is slidably disposed inside the fixed box, and the upper end of the connecting frame extends to the top of the fixed box and is fixedly connected to the bottom of the movable mounting frame outside the limiting wheel.

[0012] A further technical improvement of this utility model is that it also includes an adjustment component for adjusting the telescopic movement of the tension wheel. The adjustment component includes an electric push rod installed inside the frame via a fixed bracket. The piston rod of the electric push rod passes upward through the fixed bracket and is fixed to a fixed frame. The lower end of the movable mounting bracket on the outer side of the tension wheel is movably disposed at the upper end of the inner cavity of the fixed frame. A connecting rod is fixed to the bottom of the movable mounting bracket. The bottom of the connecting rod extends downward and contacts a pressure sensor. The pressure sensor is installed inside the fixed frame.

[0013] A further technical improvement of this utility model is that: two sets of convex rings are provided on the outer side of the first guide wheel, and two sets of grooves are provided on the limiting wheel to cooperate with the convex rings.

[0014] A further technical improvement of this utility model is that: two pairs of parallel limiting strips are vertically arranged on the inner wall of the frame, and the movable mounting bracket and fixed frame on the outer side of the limiting wheel and tension wheel are slidably arranged on the inner side of the limiting strips.

[0015] A further technical improvement of this utility model is that: a notch is provided on one side of the frame, and a baffle is hinged in the notch; the teeth and grooves are provided on the side away from the notch on the first guide wheel and the limiting wheel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model restricts the rotation direction of the first guide wheel through an anti-reverse component. The first guide wheel, together with the limiting wheel, elastically clamps the yarn. When the yarn breaks, it retracts due to tension, while the first guide wheel and the limiting wheel clamp the yarn. At the same time, the anti-reverse component locks the first guide wheel to prevent reverse rotation and avoid the yarn slipping out of the clamping of the first guide wheel and the limiting wheel. This effectively prevents the yarn from breaking and tangling during the guiding process, and facilitates quick yarn connection.

[0018] 2. This utility model uses the cooperation of teeth and grooves to stably connect the first guide wheel and the limiting wheel, preventing the limiting wheel from rotating in the opposite direction relative to the first guide wheel due to insufficient friction between the first guide wheel and the limiting wheel, thereby causing the yarn to slip off between the first guide wheel and the limiting wheel.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figure 1-5 As shown, a yarn guiding device for a cotton sock machine includes a first yarn guiding wheel 1 and a second yarn guiding wheel 2. A limiting wheel 3 for elastically clamping the yarn is provided below the first yarn guiding wheel 1. Both the first yarn guiding wheel 1 and the second yarn guiding wheel 2 are installed inside a frame 5 through a fixed mounting bracket 4. The two ends of the first yarn guiding wheel 1 and the second yarn guiding wheel 2 are rotatably connected to the fixed mounting bracket 4 through bearings. An anti-reverse component 6 is provided on the outer side of the first yarn guiding wheel 1 to prevent the first yarn guiding wheel 1 and the second yarn guiding wheel 2 from reversing. Teeth 7 are fixed in a ring around one end of the arc-shaped surface of the first yarn guiding wheel 1. A toothed groove 8 that cooperates with the teeth 7 is opened on the arc-shaped surface of the limiting wheel 3 to ensure that the first yarn guiding wheel 1 and the limiting wheel 3 rotate synchronously in opposite directions to directionally transport the yarn.

[0028] It also includes a tensioning wheel 9 located between the first guide wheel 1 and the second guide wheel 2. The tensioning wheel 9 and the limiting wheel 3 are both installed inside the frame 5 via a movable mounting bracket 21. The two ends of the tensioning wheel 9 and the limiting wheel 3 are rotatably connected to the movable mounting bracket 21 via bearings. The rotation direction of the first guide wheel 1 is restricted by the anti-reverse component 6. The first guide wheel 1 and the limiting wheel 3 work together to elastically clamp the yarn. When the yarn breaks, the yarn retracts due to tension, and the first guide wheel 1 and the limiting wheel 3 clamp the yarn. At the same time, the anti-reverse component 6 locks the first guide wheel 1 to prevent reverse rotation, which would cause the yarn to slip out of the clamping of the first guide wheel 1 and the limiting wheel 3. This effectively prevents the yarn from breaking and tangling during the yarn guiding process, and facilitates quick yarn splicing.

[0029] Please see Figure 3 As shown, the anti-reverse assembly 6 includes a ratchet 61 fixed to one end of the first guide wheel 1, and a pawl 62 engaged above the ratchet 61. The end of the pawl 62 away from the ratchet 61 is rotatably connected to the fixed mounting bracket 4. Through the cooperation of the ratchet 61 and the pawl 62, the rotation direction of the first guide wheel 1 can be effectively limited, preventing it from rotating in the opposite direction. In conjunction with the limiting wheel 3, the yarn can be clamped and limited, and the elastic retraction of the yarn can be prevented.

[0030] Please see Figure 4As shown, a fixed box 10 is fixed to the bottom of the inner cavity of the frame 5 by a mounting frame. A support spring 11 is fixed to the bottom of the inner cavity of the fixed box 10. A connecting frame 12 is fixed to the top of the support spring 11. The lower end of the connecting frame 12 is slidably disposed inside the fixed box 10. The upper end of the connecting frame 12 extends to the top of the fixed box 10 and is fixedly connected to the bottom of the movable mounting frame 21 on the outside of the limiting wheel 3. Through the cooperation of the support spring 11 and the connecting frame 12, the movable mounting frame 21 and the limiting wheel 3 are supported, so that the limiting wheel 3 is tightly attached to the lower end of the first yarn guide wheel 1, which facilitates the limiting clamping of the yarn. The supporting force provided by the support spring 11 is sufficient to offset the friction between the yarn rebound and the limiting wheel 3, which can prevent the yarn from sliding between the limiting wheel 3.

[0031] Please see Figure 5 As shown, it also includes an adjustment assembly for adjusting the telescopic movement of the tension wheel 9. The adjustment assembly includes an electric push rod 13 installed inside the frame 5 via a fixed bracket. The piston rod of the electric push rod 13 passes upward through the fixed bracket and is fixed to a fixed frame 14. The lower end of the movable mounting bracket 21 on the outside of the tension wheel 9 is movably disposed at the upper end of the inner cavity of the fixed frame 14. A connecting rod 15 is fixed to the bottom of the movable mounting bracket 21. The bottom of the connecting rod 15 extends downward and contacts a pressure sensor 16. The pressure sensor 16 is installed inside the fixed frame 14. The fixed frame 14 is telescopically moved by the electric push rod 13. Based on the data information fed back by the pressure sensor 16, the position of the fixed frame 14 is adjusted in real time to ensure that the yarn tension is maintained within a certain range, avoiding the yarn being too tight or too loose. The yarn tension can be manually controlled.

[0032] Please see Figure 3 As shown, two sets of convex rings 17 are provided on the outer side of the first yarn guide wheel 1, and two sets of grooves 18 are provided on the limiting wheel 3 to cooperate with the convex rings 17. Through the cooperation of the convex rings 17 and the grooves 18, not only can the first yarn guide wheel 1 and the limiting wheel 3 be prevented from sliding out of alignment, but the yarn can also be prevented from shaking on the first yarn guide wheel 1, effectively limiting the position of the yarn.

[0033] Please see Figure 1-2 As shown, two pairs of parallel limiting strips 19 are vertically arranged on the inner wall of the frame 5. The movable mounting bracket 21 and the fixed frame 14 on the outer side of the limiting wheel 3 and the tension wheel 9 are slidably arranged on the inner side of the limiting strips 19. The limiting strips 19 limit the position of the limiting wheel 3 and the tension wheel 9 to prevent shaking caused by the directional conveying of the yarn.

[0034] Please see Figure 1 As shown, a notch is provided on one side of the frame 5. A baffle 20 is hinged to the notch. Teeth 7 and grooves 8 are provided on the side away from the notch on the first guide wheel 1 and the limiting wheel 3. The baffle 20 can protect the notch of the frame 5, and at the same time, the notch facilitates the threading and maintenance of the yarn.

[0035] It is worth noting that the control unit of this device uses a PLC controller, which can precisely control the tension of the yarn.

[0036] In use, the limiting wheel 3 and the movable mounting bracket 21 are pressed down to separate the limiting wheel 3 from the first guide wheel 1. The yarn is then placed between the two sets of protruding rings 17 on the first guide wheel 1. The support spring 11 supports the connecting bracket 12 and the movable mounting bracket 21, causing the limiting wheel 3 to fit against the outside of the first guide wheel 1 and clamp and fix the yarn. At this time, the teeth 7 and the grooves 8 mesh. The yarn then sequentially fits against the outside of the tension wheel and the second guide wheel 2. During the yarn feeding process, the pressure sensor 16 detects the yarn tension in real time. Simultaneously, the position of the tensioning wheel 9 is adjusted using the electric push rod 13 to maintain the yarn tension within a certain range. When the yarn breaks, two sets of yarn ends are formed at the break point. Two sets of this device are installed on the yarn conveyor line. The shorter end of the yarn end can avoid tangling, while the other end of the yarn end is longer. The longer end of the yarn end is clamped by the limiting wheel 3 and the first guide wheel 1. After the yarn breaks, it elastically retracts, and the pawl 62 restricts the ratchet 61 to prevent the first guide wheel 1 from rotating in the opposite direction, thereby clamping and fixing the broken end of the yarn and preventing the yarn from tangling when it elastically retracts.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
