Description

Technical Field

[0001] This utility model relates to the field of sock processing technology, specifically to a wire device for a sock knitting machine. Background Technology

[0002] The sock knitting machine is the core equipment for realizing the automated and large-scale production of socks. The guide wire device in the sock knitting machine, which guides the yarn, is the key hub connecting the yarn supply and the knitting unit. On the one hand, the guide wire device delivers different types of yarn to the designated positions of knitting components such as knitting needles and sinkers according to process requirements through precise guidance and positioning, avoiding "misaligned needles" and "missed needles". On the other hand, it prevents yarn breakage or uneven stretching by stabilizing tension. At the same time, it uses multiple sets of independent yarn guide channels to realize the diversion and management of multiple yarns, and can synchronize with the operating rhythm of the sock knitting machine cylinder to ensure precise yarn feeding at the moment the knitting needle hooks the yarn. Ultimately, it ensures the realization of sock knitting efficiency, finished product flatness and functional characteristics.

[0003] Currently, yarn tension is typically adjusted by regulating the friction between the pressure block and the yarn, as disclosed in CN221645225U, a yarn feeding device for a knitting sock machine. During operation, continuous relative sliding friction occurs between the pressure block and the yarn. According to physical principles, mechanical energy is converted into heat energy through friction. As friction continues during operation, heat accumulates on and inside the pressure block, eventually leading to a temperature increase. If the pressure block is made of plastic or a low-melting-point metal, prolonged high temperatures can cause it to soften and deform. The working surface that was originally in contact with the yarn may become irregular, resulting in uneven stress on the yarn. At the same time, high temperatures can directly cause physical damage to the yarn, even leading to yarn breakage. This problem has not been solved in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a thread feeding device for a sock knitting machine. By setting a rotating disk, it can work with the central tube to drive the spindle to rotate when pulled by external force, thereby achieving stable thread supply. By setting an adjustment component, the friction between the clamping block and the rotating disk can be adjusted, thereby adjusting the tension of the yarn and avoiding damage to the yarn, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A guide wire device for a sock knitting machine includes a fixing component for fixing a spindle, a moving component for driving the spindle to reciprocate up and down, and an adjusting component for adjusting the yarn tension.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: A wire guide device for a sock knitting machine includes a fixing component for fixing a spindle 1. The fixing component includes a central tube 2, which is inserted into the middle of the spindle 1 and slides with the spindle 1. A clamping ring 3 is threaded onto the top of the central tube 2.

[0017] The fixing component is used to fix the spindle 1. Its core components are the central tube 2 and the clamping ring 3. The central tube 2 is inserted into the middle of the spindle 1 and forms a sliding fit with the spindle 1. It provides axial support for the spindle 1 and allows the spindle 1 to rotate synchronously with the central tube 2 to release the yarn. The clamping ring 3 at the top is fixed by a threaded connection. It can press the spindle 1 to prevent it from axially shifting when rotating or moving up and down, ensuring that the spindle 1 always operates stably with the central tube 2 as the axis, and providing basic positioning for the subsequent yarn supply process.

[0018] It also includes a moving component for driving the spindle 1 to reciprocate up and down. The moving component includes a moving seat 4, which is mounted on the surface of the reciprocating screw 5. The moving seat 4 is fixedly connected to the inside of the central tube 2. The reciprocating screw 5 is located inside the central tube 2. Limiting plates 10 are fixedly installed at the top and bottom of the reciprocating screw 5. The limiting plates 10 slide with the inside of the central tube 2 and can rotate inside the central tube 2. A support rod 11 is fixedly installed below the bottom limiting plate 10 of the reciprocating screw 5. The support rod 11 is fixedly connected to one side of the top surface of the mounting base 12. The support rod 11 slides with the inside of the central tube 2 and can rotate inside the central tube 2.

[0019] By setting up a moving component, the spindle 1 achieves up-and-down reciprocating motion during the yarn feeding process. The reciprocating screw 5 is set inside the central tube 2, and the moving seat 4 on its surface is fixedly connected to the central tube 2. When the spindle 1 and the central tube 2 rotate to release the yarn, the moving seat 4 will rotate on the reciprocating screw 5. The rotating moving seat 4 moves up and down on the surface of the reciprocating screw 5. The moving seat 4 drives the central tube 2 to move up and down along the axial direction, thereby driving the spindle 1 to rise and fall synchronously. This design can keep the yarn exit position horizontal with the guide ring 16 at all times, avoid the yarn exit height deviation caused by the change of yarn winding diameter on the spindle 1, reduce the friction and up-and-down swing between the yarn and the guide ring 16, and ensure the stability of the yarn feeding path.

[0020] It also includes an adjustment component for adjusting yarn tension. The adjustment component includes a rotating disk 6, which is fixedly installed at the bottom of the central tube 2. The rotating disk 6 is rotatably engaged with the adjustment seat 7. An adjustment screw 8 is threadedly installed on one side of the adjustment seat 7. A clamping block 9 is rotatably installed at one end of the adjustment screw 8. The clamping block 9 abuts against the side wall of the rotating disk 6. The adjustment seat 7 is slidably engaged with the support rod 11. A limit key 13 is fixedly installed in the middle of the bottom of the adjustment seat 7. A limit groove 14 is opened on one side of the support rod 11. The limit key 13 is slidably engaged with the limit groove 14. An installation groove matching the shape of the clamping block 9 is opened inside the adjustment seat 7. The clamping block 9 is slidably engaged with the installation groove. A limit ring 17 is fixedly installed at the bottom of the rotating disk 6. The limit ring 17 is rotatably connected to the adjustment seat 7.

[0021] The adjustment component is the key structure for controlling yarn tension. Tension adjustment is achieved through the cooperation of the rotating disk 6, the adjusting seat 7, the adjusting screw 8, and the clamping block 9. The rotating disk 6 is fixed to the bottom of the central tube 2 and rotates with it. The clamping block 9 is pressed against the side wall of the rotating disk 6 by the adjusting screw 8. The friction between the two will hinder the rotation of the rotating disk 6. When the sock knitting machine pulls the yarn, the tension of the yarn must overcome this friction to drive the rotating disk 6 and the spindle 1 to rotate and feed the yarn. By turning the adjusting screw 8, the pressure of the clamping block 9 on the rotating disk 6 can be changed, thereby adjusting the magnitude of the friction and ultimately achieving precise control of the yarn tension. This adjustment method avoids the problem of heat damage caused by direct friction between the pressure block and the yarn in traditional methods, and improves the stability of tension control.

[0022] A mounting rod 15 is fixedly mounted on the other side of the top surface of the mounting base 12. A guide ring 16 is slidably mounted on the top of the mounting rod 15. A tightening screw is threaded on one side of the mounting rod 15, and the tightening screw abuts against the surface of the guide ring 16.

[0023] The guide ring 16 is a guiding structure for the yarn before it enters the knitting unit of the sock knitting machine. Its core function is to position and comb the yarn drawn from the spindle 1, ensuring that the yarn enters the knitting area of ​​the sock knitting machine in a straight line, and avoiding additional friction or tangling of the yarn with other parts due to path deviation. At the same time, the guide ring 16 can slide along the mounting rod 15 and be fixed by the tightening screw, and its height position can be adjusted according to different sock knitting process requirements to adapt to various yarn directions, further ensuring the accuracy of yarn supply.

[0024] In practical use, after installing the device in the designated position, first slip the spindle 1 to be used onto the outside of the central tube 2, then tighten the clamping ring 3 at the top of the central tube 2 until the clamping ring 3 presses against the top surface of the spindle 1 to prevent the spindle 1 from shifting axially during subsequent operation; next, adjust the position of the guide ring 16 according to the yarn supply height requirements of the sock knitting machine, slide the guide ring 16 along the mounting rod 15 to the appropriate height, and tighten the clamping screw on the side wall of the mounting rod 15 to fix the guide ring 16; then preset the tension: by turning the adjusting screw 8 on one side of the adjusting seat 7, push the clamping block 9 to slide in the mounting groove, changing the contact pressure between the clamping block 9 and the side wall of the rotating disk 6. The greater the pressure, the stronger the friction, and the greater the yarn tension, until the tension value is adjusted to be suitable for the current yarn material. Rotate spindle 1 and adjust its height to bring the yarn exit position of spindle 1 to the same level as guide ring 16. Then pull the yarn through guide ring 16 and connect it to the sock knitting machine. After starting the sock knitting machine, the pulling force generated by the sock knitting machine on the yarn will drive spindle 1 and center tube 2 to rotate synchronously. The rotating disk 6 at the bottom of center tube 2 will rotate with it (it needs to overcome the friction of the clamping block 9) to achieve stable yarn supply. At the same time, when center tube 2 rotates, it will drive the internal moving seat 4 to rotate on the surface of reciprocating screw 5. The moving seat 4 moves up and down along the thread track of reciprocating screw 5, thereby driving center tube 2 and spindle 1 to rise and fall synchronously, ensuring that the yarn exit position is always horizontal with guide ring 16, and finally the yarn is accurately delivered to the knitting unit of the sock knitting machine after being combed by guide ring 16.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
