Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a yarn guide with a magnetic tension compensation structure. Background Technology

[0002] The yarn guide is a key loop-forming component in textile machinery. Its core function is to guide the yarn into the knitting needles in equipment such as weft knitting machines, circular knitting machines, and sock knitting machines, ensuring uniform yarn tension and optimizing the loop-forming process. By adjusting the installation position of the yarn guide, the yarn padding angle can be controlled to avoid problems such as missed needles or needle hook collisions. Existing publication number CN101363162A discloses a yarn guide for a circular knitting machine, comprising a support and a yarn feeding head made of ceramic material. The upper part of the yarn feeding head has a yarn feeding hole, and the lower part is a stepped yarn feeding head connecting part. The upper part of the support has a stepped support connecting part. The yarn feeding head and the support are bonded together after their stepped surfaces align. The connection between the support and the yarn feeding head is secured with bolts. Because the yarn feeding head is made entirely of ceramic, during operation, friction-induced yarn breakage or incomplete yarn feeding is reduced, thus improving the quality of the woven fabric. Furthermore, it increases the hardness and wear resistance of the yarn feeding part, extending the service life of the yarn guide. In the process of developing this utility model, the inventors discovered the following problems with the existing technology: Currently, most yarn guides use a single spring as the tension compensation component, without a precise guiding and limiting structure. The spring is prone to skew and displacement due to long-term compression, resulting in inconsistent tension compensation force and inability to maintain stable tension in the line. Some yarn guides with magnetic compensation do not have a magnetic block alignment and guiding structure. The magnetic block is prone to misalignment after being subjected to force, interrupting or disrupting the transmission of magnetic repulsion force, which further aggravates tension fluctuations. Therefore, a yarn guide with a magnetic tension compensation structure is proposed to address the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a yarn guide with a magnetic tension compensation structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a yarn guide with a magnetic tension compensation structure, comprising a yarn guide body and a magnetic tension compensation component. The yarn guide component includes a sliding adjustment base, a yarn inlet seat, and a magnetic tension compensation component. Two sets of yarn inlets are bolted to the top of the sliding adjustment base, and a magnetic tension compensation component is placed between the two sets of yarn inlets. The magnetic tension compensation assembly includes a tension adjustment disc, an assembly plate, and a first magnetic block. The assembly plate is engaged with the lower part of the tension adjustment disc, and the first magnetic block is bolted to the bottom of the assembly plate.

[0005] Preferably, the magnetic tension compensation component further includes a spring, a plug-in post, a docking seat, a locking post, a second magnetic block, and a plug-in groove. Two sets of springs are provided and located on both sides of the first magnetic block. A plug-in post is inserted into the inside of the spring, and a docking seat is inserted below the plug-in post. A second magnetic block is provided between the two sets of plug-in posts. A plug-in groove is provided on the outer surface of both the first and second magnetic blocks. A bolt is inserted into the plug-in groove of the first magnetic block and fixed inside the assembly plate. A sliding post is inserted into the plug-in groove of the first magnetic block below the bolt. The sliding post passes through the plug-in groove of the second magnetic block.

[0006] Preferably, a placement cavity is provided at the edge of the docking seat, and an elastic compression plate is installed inside the placement cavity by bolts. Locking posts are provided on both sides of the docking seat, and a plate is installed on the outer diameter surface of the locking posts. The cable inlet includes a placement seat, an arc groove and a connecting plate. An arc groove is provided on the top of the placement seat, and a connecting plate is detachably connected to the edge of the placement seat by a buckle. Two sets of connecting plates are provided.

[0007] Preferably, the cable inlet also includes a cable threading shaft and a cable threading groove, with the cable threading shaft fixedly connected between the two sets of connecting plates, and a cable threading groove provided at the center of the cable threading shaft.

[0008] Preferably, the sliding adjustment base includes a frame, sliding bars, and limiting posts. The frame has two sets of sliding bars inside, and the limiting posts are inserted between the two sets of sliding bars. A screw is provided between the two sets of sliding bars and the limiting posts. There are two sets of screws, and a mating sleeve is provided at the center of the two sets of screws. A rotating disk is provided at the end of each set of screws away from the mating sleeve.

[0009] The technical effects and advantages of this utility model are as follows: 1. Compared with the prior art, this yarn guide with a magnetic tension compensation structure ensures that the magnetic repulsion force is always transmitted through the arrangement of the first and second magnetic blocks with the same polarity, and the guiding and cooperating structure of the sliding column and the insertion groove, so as to provide a continuous and controllable core support force for tension adjustment; at the same time, the combination of springs and insertion columns arranged symmetrically on both sides avoids the skew and offset when the springs extend and retract, and can also form a double buffer in conjunction with the magnetic force.

[0010] 2. Compared with the prior art, when the yarn guide with magnetic tension compensation structure experiences pressure fluctuations due to fluctuations in linear speed and slight changes in yarn diameter, the tension adjustment disc can quickly absorb the pressure and transmit it to the compensation component. The synergistic effect of magnetic force and elastic force can adjust the force state of the elastic extrusion disc in real time, quickly offset the pressure changes, and ensure that the yarn is always delivered with stable tension.

Detailed Implementation

[0017] 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. Example

[0018] As attached Figures 1 to 5 The yarn guide with a magnetic tension compensation structure shown includes a yarn guide body 1 and a magnetic tension compensation component 4. The yarn guide component includes a sliding adjustment base 2, a yarn inlet seat 3 and a magnetic tension compensation component 4. Two sets of yarn inlets 3 are bolted to the top of the sliding adjustment base 2, and the magnetic tension compensation component 4 is placed between the two sets of yarn inlets 3. The magnetic tension compensation component 4 includes a tension adjusting disc 8, an assembly plate 9, and a first magnetic block 10. The tension adjusting disc 8 is the component that directly receives the line tension. Its lower part is fixed to the assembly plate 9 by a snap-fit ​​connection. The snap-fit ​​structure ensures the firmness of the connection between the two and facilitates assembly and subsequent maintenance. The assembly plate 9 is snap-fitted to the lower part of the tension adjusting disc 8 and plays the role of intermediate conduction. The first magnetic block 10 is installed at the bottom of the assembly plate 9 by bolts. The bolt connection ensures the stability of the first magnetic block 10 and prevents it from shifting during tension adjustment, thus ensuring the stability of magnetic force adjustment.

[0019] When using the yarn guide, the yarn is passed through the inlet seat 3 and placed into the groove of the elastic compression disc 18 of the magnetic tension compensation component 4. The yarn then passes through the inlet seat 3 on the other side, thus guiding the yarn. The yarn continues to move. During this movement, the yarn compression tension adjusting disc 8, along with the attraction between the like poles of the first magnetic block 10 and the second magnetic block 15, and the compression of the spring 11, maintains the tension of the elastic compression disc 18. This ensures stable yarn delivery even when the yarn experiences varying pressures during movement, thanks to the cooperation of the elastic compression disc 18. As a preferred implementation, to further improve the stability and response speed of tension compensation, The magnetic tension compensation component 4 also includes a spring 11, a plug post 12, a docking seat 13, a locking post 14, a second magnetic block 15, and a plug groove 16. There are two sets of springs 11, located on both sides of the first magnetic block 10. The plug post 12 is inserted into the inside of the spring 11. The plug post 12 not only guides the extension and retraction of the spring 11 to prevent the spring 11 from tilting or deviating, but also transmits the force. The docking seat 13 is inserted below the plug post 12. The docking seat 13 is located between the two sets of plug posts 12 and the second magnetic block 15 is arranged between the two sets of plug posts 12. The second magnetic block 15 and the first magnetic block 10 are arranged with the same polarity to ensure that they can generate a repulsive force, providing core magnetic support for tension adjustment.

[0020] In a preferred embodiment, to facilitate the installation and force transmission of each magnetic block, the outer surfaces of the first magnetic block 10 and the second magnetic block 15 are provided with insertion slots 16. The insertion slots 16 serve a dual function of installation positioning and component guidance. A bolt is inserted into the insertion slot 16 of the first magnetic block 10 and fixed inside the assembly plate 9. A sliding post is inserted into the insertion slot 16 of the first magnetic block 10 below the bolt. The sliding post passes through the insertion slot 16 of the second magnetic block 15 from top to bottom, realizing the sliding guide cooperation between the first magnetic block 10 and the second magnetic block 15, ensuring that the two maintain a precise alignment relationship during relative movement, and ensuring the stability of magnetic force adjustment.

[0021] In a preferred embodiment, to achieve the installation and fixation of the elastic extrusion disc 18, a placement cavity 17 is provided at the edge of the docking seat 13. The elastic extrusion disc 18 is installed inside the placement cavity 17 by bolts. The size of the placement cavity 17 is adapted to the elastic extrusion disc 18. Locking posts 14 are provided on both sides of the docking seat 13. The outer diameter surface of the locking posts 14 is equipped with a disc body. The locking posts 14 and the disc body cooperate to form a positioning structure, which can lock the docking seat 13 in the preset installation position and prevent it from shifting during operation.

[0022] In a preferred embodiment, the inlet seat 3 includes a placement seat 5, an arc groove 501, and a connecting plate 6. The arc groove 501 is provided on the upper part of the placement seat 5. The arc groove 501 can fit and conform to the surface of the line, playing a preliminary limiting and guiding role for the line. The connecting plate 6 is detachably connected to the edge of the placement seat 5 by a snap fastener. There are two sets of connecting plates 6. The snap fastener connection method not only ensures the firmness of the connection between the connecting plate 6 and the placement seat 5, but also facilitates subsequent disassembly, maintenance, and component replacement.

[0023] In a preferred embodiment, the cable inlet 3 also includes a cable threading shaft 7 and a cable threading groove 701. The cable threading shaft 7 is fixedly connected between the two sets of connecting plates 6, and the cable threading groove 701 is provided at the center of the cable threading shaft 7.

[0024] In a preferred embodiment, the sliding adjustment base 2 includes a frame 19, sliding bars 20, and limiting posts 21. The frame 19 serves as the external support frame of the sliding adjustment base 2, and a sliding space is reserved inside it. Two sets of sliding bars 20 are arranged in parallel within the sliding space. Two sets of sliding bars 20 are arranged inside the frame 19, and the limiting posts 21 are inserted between the two sets of sliding bars 20. The limiting posts 21 can effectively limit the sliding stroke of the sliding bars 20, prevent the sliding bars 20 from sliding excessively and causing component collisions, and at the same time improve the stability of the sliding bars 20 during the sliding process.

[0025] In a preferred embodiment, two sets of sliding bars 20 are provided with screws 22 between the limiting posts 21. There are two sets of screws 22, and a connecting sleeve is provided at the center of the two sets of screws 22. A rotating disk 23 is provided at the end of each set of screws 22 away from the connecting sleeve. The rotating disk 23 provides a convenient adjustment end for the operator. By rotating the rotating disk 23, the screws 22 can be driven to rotate, thereby driving the two sets of sliding bars 20 to slide synchronously in opposite directions, realizing the adjustment of the installation spacing of the inlet seat 3, and adapting to the yarn guiding requirements of different specifications of lines.

[0026] In this embodiment, the screw 22, the first magnetic block 10, and the second magnetic block 15 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here.

[0027] The working process of this utility model is as follows: First, the yarn to be guided is passed through the guide structure of the inlet seat 3 on one side. Then, the yarn is precisely embedded into the groove of the elastic extrusion plate 18 in the magnetic tension compensation component 4, so that the yarn and the tension compensation component make effective contact. Finally, the yarn is passed through the inlet seat 3 on the other side to complete the construction of the entire yarn guide path. After the yarn enters the continuous movement state, it will generate a continuous extrusion force on the tension adjustment disc 8 during the movement. At this time, through the attraction force between the first magnetic block 10 and the second magnetic block 15, combined with the elastic extrusion action of the spring 11, the force balance of the elastic extrusion plate 18 can be maintained in real time. Even if the yarn experiences different pressures due to factors such as fluctuations in yarn speed and slight changes in yarn diameter during the movement, the elastic extrusion plate 18 can adjust its own force in real time under the synergistic action of magnetic force and elastic force, thereby offsetting the changes in yarn pressure and ensuring that the yarn is always transported with stable tension. The above is the working principle of this yarn guide with a magnetic tension compensation structure.
