Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a yarn feeding and guiding device for textile machinery. Background Technology

[0002] In the textile production process, the yarn guiding device is a key component of the yarn feeding system. Traditional yarn guiding devices have a long-term friction between the yarn guide wheel and the yarn, resulting in localized wear. However, the existing structure requires the entire yarn guide wheel to be replaced, which causes a lot of material waste. Moreover, replacing the entire yarn guide wheel requires disassembling surrounding components, which takes a long time each time and affects the continuity of production. The operation requires the use of tools such as wrenches and screwdrivers, which requires high technical skills from the operators and poses a risk of losing parts. Utility Model Content

[0003] In view of the problems existing in the current yarn feeding and guiding devices for textile machines, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a yarn feeding and guiding device for textile machines, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A yarn feeding and guiding device for a textile machine includes an L-shaped plate and a rotating plate. The rotating plate is disposed on one side of the L-shaped plate. A rotating rod is rotatably mounted on the lower end of the L-shaped plate, and the other end of the rotating rod is fixedly connected to the rotating plate. A crossbar is disposed between the upper ends of the L-shaped plate and the rotating plate. One end of the crossbar is rotatably connected to the L-shaped plate. A yarn guide wheel body is fixedly sleeved on the wall of the crossbar. A wear-resistant sleeve is slidably sleeved on the outer wall of the yarn guide wheel body. A first support ring and a second support ring are respectively disposed on both sides of the wear-resistant sleeve. The first support ring is fixedly sleeved with a horizontal tube, and the second support ring is movably sleeved with the horizontal tube. A first limiting mechanism is disposed at the end of the crossbar away from the L-shaped plate to restrict the rotation of the crossbar. A second limiting mechanism is disposed on the upper surface of the lower end of the L-shaped plate to restrict the rotation of the rotating rod.

[0007] Preferably, the first limiting mechanism includes a stop block and a plug rod. A cavity is provided at one end of the crossbar near the rotating plate. The stop block is slidably disposed inside the cavity. The plug rod is fixedly disposed on the side of the stop block near the rotating plate. An insertion hole is provided on the side wall of the rotating plate at a position corresponding to the plug rod. One end of the plug rod extends to the outside of the cavity and is inserted into the insertion hole.

[0008] Preferably, the second limiting mechanism includes a threaded rod and a limiting plate. The limiting plate is fixedly sleeved on the rod wall of the rotating rod. A side plate is fixedly provided on the upper surface of the lower end of the L-shaped plate. The threaded rod is threadedly sleeved inside the side plate. A through hole is opened on the surface of the rotating plate. One end of the threaded rod is inserted into the through hole.

[0009] Preferably, a support rod is fixedly provided on the side of the second support ring away from the wear-resistant sleeve, and a stop block is fixedly provided on the side of the support rod away from the second support ring, the stop block abutting against one side of the rotating plate.

[0010] Preferably, both the first support ring and the second support ring have multiple balls rolled and embedded on the side near the wear-resistant sleeve.

[0011] Preferably, a spring is fixedly provided on the side of the stop block away from the insertion rod, and the other end of the spring is fixedly connected to the inner wall of the cavity.

[0012] Preferably, all of the balls are wear-resistant steel balls.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model, by sliding a wear-resistant sleeve onto the outside of the guide wheel body, allows the wear-resistant sleeve to be removed and replaced by simply releasing the first and second limiting mechanisms and rotating the rotating plate around the rotating rod as an axis when the surface of the wear-resistant sleeve is worn. Compared with the traditional method of replacing the entire guide wheel, this not only saves materials but also improves replacement efficiency.

[0015] 2. In this utility model, the first support ring and the second support ring are in contact with the wear-resistant sleeve through wear-resistant steel balls, which ensures that the position of the second support ring is stable during the replacement of the wear-resistant sleeve and avoids yarn displacement caused by installation deviation.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-3 A yarn feeding and guiding device for a textile machine includes an L-shaped plate 1 and a rotating plate 3. The rotating plate 3 is disposed on one side of the L-shaped plate 1. A rotating rod 2 is rotatably mounted on the lower end of the L-shaped plate 1, and the other end of the rotating rod 2 is fixedly connected to the rotating plate 3. A crossbar 7 is disposed between the upper ends of the L-shaped plate 1 and the rotating plate 3. One end of the crossbar 7 is rotatably connected to the L-shaped plate 1. A yarn guide wheel body is fixedly sleeved on the wall of the crossbar 7. A wear-resistant sleeve 9 is slidably sleeved on the outer wall of the yarn guide wheel body. A first support ring 8 and a second support ring 10 are respectively disposed on both sides of the wear-resistant sleeve 9. The support ring 8 is fixedly sleeved with the horizontal tube, and the second support ring 10 is movably sleeved with the horizontal tube. Multiple balls 11 are rolledly embedded on the side of the first support ring 8 and the second support ring 10 near the wear-resistant sleeve 9, so that the wear-resistant sleeve 9 can rotate smoothly relative to the first support ring 8 and the second support ring 10. The multiple balls 11 are all wear-resistant steel balls, which improves the wear resistance of the balls 11. A first limiting mechanism is provided at the end of the crossbar 7 away from the L-shaped plate 1 to limit the rotation of the crossbar 7. A second limiting mechanism is provided on the upper surface of the lower end of the L-shaped plate 1 to limit the rotation of the rotating rod 2.

[0024] Reference Figure 1-3 The first limiting mechanism includes a stop block 15 and a rod 13. A cavity is provided at one end of the crossbar 7 near the rotating plate 3. The stop block 15 is slidably disposed inside the cavity. The rod 13 is fixedly disposed on the side of the stop block 15 near the rotating plate 3. An insertion hole is provided on the side wall of the rotating plate 3 at a position corresponding to the rod 13. One end of the rod 13 extends to the outside of the cavity and is inserted into the insertion hole. Pushing the rod 13 towards the side near the crossbar 7 will push the rod 13 out of the insertion hole, thereby releasing the limiting of the upper end of the rotating plate 3. A spring 16 is fixedly disposed on the side of the stop block 15 away from the rod 13. The other end of the spring 16 is fixedly connected to the inner wall of the cavity to facilitate the reset of the rod 13.

[0025] Reference Figure 1-3The second limiting mechanism includes a threaded rod 6 and a limiting plate 4. The limiting plate 4 is fixedly sleeved on the rod wall of the rotating rod 2. A side plate 5 is fixedly installed on the upper surface of the lower end of the L-shaped plate 1. The threaded rod 6 is threadedly sleeved inside the side plate 5. A through hole is opened on the surface of the rotating plate 3. One end of the threaded rod 6 is inserted into the through hole. Rotating the threaded rod 6 causes the threaded rod 6 to leave the through hole, thereby releasing the limiting of the rotating rod 2.

[0026] Reference Figure 1-3 A support rod 12 is fixedly installed on the side of the second support ring 10 away from the wear-resistant sleeve 9. A stop block 14 is fixedly installed on the side of the support rod 12 away from the second support ring 10. The stop block 14 abuts against one side of the rotating plate 3, which can keep the position of the second support ring 10 stable.

[0027] When using this invention, if the wear-resistant sleeve 9 needs to be replaced due to wear, first rotate the threaded rod 6 to disengage it from the through hole of the rotating plate 3, releasing the limiting position of the rotating rod 2. Then, press the insertion rod 13 to compress the spring 16, disengaging the insertion rod 13 from the insertion hole of the rotating plate 3, thus releasing the limiting position on the upper end of the rotating plate 3. The rotating plate 3 can then be rotated around the rotating rod 2 to a horizontal position. At this point, first slide off the second bevel ring 10, thus releasing the limiting position on the side of the wear-resistant sleeve 9 away from the L-shaped plate 1. Pull the wear-resistant sleeve 9 away from the L-shaped plate 1 to disengage it from the guide wheel body. After replacing the new wear-resistant sleeve, reverse the operation to reset. The entire process requires no tools and can be completed quickly by a single person without affecting the operation of other parts of the textile machine.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
