Description

Technical Field

[0001] This utility model relates to the field of ribbon production, and in particular to a yarn guiding device for a loom with an anti-wear structure for ribbon production. Background Technology

[0002] As a common accessory, webbing is widely used in clothing, footwear, bags, home decoration, and many other fields, with its applications covering almost every aspect of daily life. The production process of webbing is inseparable from professional weaving machines. These machines, through precise design and operation, can weave various yarns into the required webbing. During the operation of the weaving machine, the yarn guiding device plays a crucial role. It is responsible for guiding the yarn in an orderly manner to the weaving area of ​​the weaving machine, ensuring that the yarn does not become disordered or break during the weaving process, thereby guaranteeing the quality of the webbing and the smooth progress of production.

[0003] In daily work, it has been found that traditional yarn guide components are usually designed with fixed holes or fixed surfaces. When the yarn passes through these components, it forms sliding friction with their surfaces. This friction not only leads to faster wear of the yarn guide components, but also easily causes scratches on the yarn surface, affecting the quality and service life of the yarn. In addition, during the operation of the yarn, the tension fluctuations will further aggravate the impact friction with the yarn guide components, making the wear and scratch problems more serious, thereby reducing the efficiency of the entire textile process and the quality of the products. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional yarn guide components in the prior art are usually designed with fixed holes or fixed surfaces, causing sliding friction between the yarn and these components as it passes through. This friction not only leads to rapid wear of the yarn guide components but also easily scratches the yarn surface, affecting the quality and service life of the yarn. Furthermore, during yarn operation, tension fluctuations further exacerbate the impact friction with the yarn guide components, making the wear and scratch problems more severe, thereby reducing the efficiency and product quality of the entire textile process. Therefore, this invention proposes a yarn guide device for webbing production with an anti-wear structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a yarn guiding device for a loom with an anti-wear structure for ribbon production, comprising a housing, yarn guiding openings on both sides of the housing, two first yarn guiding rollers rotatably connected to the inner wall of the housing, two buffer components symmetrically arranged in the middle of the two first yarn guiding rollers, and an anti-wear component provided on one side of the yarn guiding opening; The buffer assembly includes a first fixing block, a second yarn guide roller, and a buffer cylinder. There are two first fixing blocks, which are symmetrically installed on the inner wall of the housing. The second yarn guide roller is located in the middle of the two first fixing blocks. The anti-wear component includes a slide rail, a receiving plate, and a fixing plate. There are two slide rails, which are symmetrically installed at the bottom of the yarn guide opening on one side of the housing. There are two receiving plates, which are symmetrically arranged on one side of the slide rail. The fixing plate is fixedly installed at the bottom of the slide rail on one side of the housing.

[0006] As a further embodiment of this utility model, a second fixed block is rotatably connected to both sides of the second yarn guide roller, and a first rotating block is rotatably connected to the surface of the second fixed block.

[0007] As a further embodiment of this invention, a second rotating block is fixedly installed on the side of the buffer cylinder away from the first rotating block, and the second rotating block is rotatably connected to the surface of the first fixed block.

[0008] As a further embodiment of this utility model, a guide rod is fixedly installed on one side of the first rotating block, and a piston plate is fixedly installed at the end of the guide rod. The piston plate is slidably connected to the inner wall of the buffer cylinder. A buffer spring is sleeved on the surface of the guide rod. One end of the buffer spring is fixedly installed on the surface of the piston plate, and the other end is fixedly installed on the inner wall of the buffer cylinder.

[0009] As a further embodiment of this utility model, a slider is fixedly installed at the bottom of the receiving plate, the slider is slidably connected to the surface of the slide rail, and a protrusion is provided at the end of the receiving plate, and a third yarn guide roller is rotatably connected to the surface of the protrusion.

[0010] As a further embodiment of this utility model, a knob is rotatably connected to the top of the fixing plate, and a gear is fixedly installed at the output end of the knob. The gear is rotatably connected to the middle position of two slide rails on one side of the housing.

[0011] As a further embodiment of this utility model, the end face of the third yarn guide roller is provided with a groove, which can guide the yarn. Both of the receiving plates are fixedly installed with racks at their bottoms, and the racks mesh with gears.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the buffer cylinder can be rotated through the first fixed block via the second rotating block. When the yarn is tensioned, displacement redundancy is generated, and the buffer spring buffers the piston plate and applies a buffering force to the second guide roller, preventing excessive instantaneous pressure from the yarn from causing severe friction on the device. The knob can drive the gear to rotate, which in turn drives two racks, causing the receiving plate to slide along the slide rail under the traction of the racks, and allowing the two third guide rollers to be in close contact with the yarn. Since the surface of the third guide roller has grooves, after the yarn is embedded in the grooves, it generates an axial force with the traction movement of the loom, causing the guide wheel to rotate slowly while moving back and forth along the wheel axis, so that the yarn contact points are evenly distributed on the surface of the third guide roller along the grooves, thereby preventing the yarn from sliding and rubbing against the housing through the guide opening.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a yarn guiding device for a loom with an anti-wear structure for ribbon production, including a housing 1, yarn guiding openings 2 on both sides of the housing 1, two first yarn guiding rollers 3 rotatably connected to the inner wall of the housing 1, two buffer components 4 symmetrically arranged in the middle of the two first yarn guiding rollers 3, and an anti-wear component 5 arranged on one side of the yarn guiding opening 2.

[0016] In this embodiment: the buffer assembly 4 includes a first fixing block 41, a second yarn guide roller 42 and a buffer cylinder 43. There are two first fixing blocks 41, which are symmetrically installed on the inner wall of the housing 1. The second yarn guide roller 42 is located in the middle of the two first fixing blocks 41. The second yarn guide roller 42 is located in the middle of the first fixing block 41 and the second yarn guide roller 42. The anti-wear component 5 includes a slide rail 51, a receiving plate 52, and a fixing plate 53. There are two slide rails 51, which are symmetrically installed on the bottom of the yarn guide opening 2 on one side of the housing 1. There are two receiving plates 52, which are symmetrically arranged on one side of the slide rail 51. The fixing plate 53 is fixedly installed on the bottom of the slide rail 51 on one side of the housing 1.

[0017] To cushion yarn tension impacts and reduce severe wear caused by excessive instantaneous pressure, please refer to [link / reference needed]. Figure 2-3 The second guide roller 42 is rotatably connected to both sides of the second fixed block 421. The surface of the second fixed block 421 is rotatably connected to the first rotating block 422. The buffer cylinder 43 is fixedly installed on the side away from the first rotating block 422. The second rotating block 431 is rotatably connected to the surface of the first fixed block 41. Through the second rotating block 431, the buffer cylinder 43 can be rotated through the first fixed block 41, and displacement redundancy is generated when the yarn is tensioned. A guide rod 423 is fixedly installed on one side of the first rotating block 422, and a piston plate 424 is fixedly installed at the end of the guide rod 423. The piston plate 424 is slidably connected to the inner wall of the buffer cylinder 43. A buffer spring 425 is sleeved on the surface of the guide rod 423. One end of the buffer spring 425 is fixedly installed on the surface of the piston plate 424, and the other end is fixedly installed on the inner wall of the buffer cylinder 43. When the yarn generates instantaneous tension due to external factors, the guide rod 423 will slide on the inner wall of the shock absorber cylinder under the drive of the piston plate 424, and the buffer spring 425 will buffer the piston plate 424 and apply a buffering force to the second yarn guide roller 42 to prevent the excessive instantaneous pressure of the yarn from causing severe friction on the device.

[0018] To prevent the yarn from slipping and rubbing as it passes through yarn guide 2, please refer to... Figure 4-5 A slider 521 is fixedly installed at the bottom of the receiving plate 52. The slider 521 is slidably connected to the surface of the slide rail 51. A protrusion is provided at the end of the receiving plate 52. A third yarn guide roller 523 is rotatably connected to the surface of the protrusion. A groove is opened on the end face of the third yarn guide roller 523. The groove can guide the yarn. Since the groove is opened on the surface of the third yarn guide roller 523, after the yarn is embedded in the groove, it generates an axial force with the traction movement of the loom. At the same time, it drives the yarn guide wheel to rotate slowly and move back and forth along the wheel axis so that the yarn contact point is evenly distributed on the surface of the third yarn guide roller 523 along the groove. A knob 531 is rotatably connected to the top of the fixed plate 53. A gear 532 is fixedly installed at the output end of the knob 531. The gear 532 is rotatably connected to the middle position of two slide rails 51 on one side of the housing 1. The knob 531 can drive the gear 532 to rotate. The gear 532 will drive two racks 522, so that the receiving plate 52 slides along the slide rail 51 under the traction of the racks 522, and the two third yarn guide rollers 523 can be in close contact with the yarn to prevent the yarn from sliding and rubbing against the housing 1 through the yarn guide opening 2.

[0019] Working principle: The yarn enters the housing 1 from the yarn guide 2 under the drive of the loom. The first yarn guide roller 3 guides and tensions the yarn. Next, the yarn passes through the second rotating block 431, allowing the buffer cylinder 43 to rotate through the first fixed block 41. When the yarn is tensioned, displacement redundancy is generated, and the buffer spring 425 buffers the piston plate 424 and applies a buffering force to the second yarn guide roller 42, preventing excessive instantaneous pressure from the yarn from causing severe friction on the device. The gear 5 can be driven by the knob 531. When the gear 532 rotates, it drives the two racks 522, causing the receiving plate 52 to slide along the slide rail 51 under the traction of the racks 522. This allows the two third guide rollers 523 to be in close contact with the yarn. Since the surface of the third guide roller 523 has grooves, after the yarn is embedded in the grooves, it generates an axial force with the traction of the loom. This causes the guide roller to rotate slowly while moving back and forth along the wheel axis, so that the yarn contact points are evenly distributed on the surface of the third guide roller 523 along the grooves. This prevents the yarn from sliding and rubbing against the housing 1 through the guide opening 2.

[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
