Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a yarn guiding device. Background Technology

[0002] In the textile production process, when yarn is used for spinning, a guiding device is needed to guide the yarn and ensure that the yarn is fed in an orderly manner.

[0003] Chinese utility model patent CN220300001U discloses an intelligent yarn guiding device for polyester fabric processing, including a mounting base, a fixed frame, a guide groove, a height adjustment mechanism, and a detachable mechanism. The top surface of the mounting base is fixedly connected to the bottom surface of the fixed frame, and the side surface of the fixed frame has a guide groove. The height adjustment mechanism includes a servo motor, a threaded column, a moving block, and a limiting plate. The servo motor is fixedly connected to the top surface of the fixed frame, and the output end of the servo motor is connected to the threaded column. The moving block is threadedly fitted onto the surface of the threaded column. A yarn guide plate is fixedly connected to one side surface of the moving block, and the other side surface of the moving block is fixedly connected to the limiting plate. This guiding device can automatically adjust the height of the yarn guide plate.

[0004] When the guiding device disclosed in the above-mentioned utility model patent is used, the yarn passes through the yarn guide tube to guide the yarn. Since the inner diameter of the yarn guide tube is fixed, it cannot be adapted to yarns of different thicknesses. Yarns that are too thick are difficult to enter the yarn guide tube and will rub against the yarn guide tube, causing damage or even breakage to the yarn surface. Yarns that are too thin are prone to shaking in the yarn guide tube, resulting in unstable yarn tension and affecting the normal progress of textile processing. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a yarn guiding device, which solves the problem that the existing guiding devices cannot be adapted to yarns of different thicknesses.

[0006] According to an embodiment of this utility model, a yarn guiding device includes a mounting base, on which a yarn guide cylinder is provided, and the yarn guide cylinder has a yarn passage hole. At least three grooves are equally spaced along the circumference of the yarn passage hole on the yarn guide cylinder, and movable blocks are respectively provided in each groove. The length direction of the groove is perpendicular to the radial direction of the yarn passage hole. Any two adjacent blocks are in contact with each other and cover the yarn passage hole. As the blocks move along the grooves, the area of ​​the blocks covering the yarn passage hole increases or decreases. A rotatable adjusting cover is also fitted onto the yarn guide cylinder, and a driving assembly connected to the adjusting cover is provided on the mounting base. The blocks are located between the yarn guide cylinder and the adjusting cover. The adjusting cover has a through hole concentric with the yarn passage hole. Multiple through grooves are equally spaced along the circumference of the through hole on the adjusting cover, and the number of through grooves is the same as the number of blocks. Guide rods are respectively provided on each block, and the guide rods extend into the through grooves one by one and abut against the adjusting cover.

[0007] Furthermore, the yarn guide tube is also provided with a buffer washer, which is located inside the yarn guide hole and covers the inner wall of the yarn guide hole.

[0008] Furthermore, each of the stops is provided with a buffer pad, and the buffer pads on each stop are arranged in a ring.

[0009] Furthermore, the adjusting cover is provided with an arc-shaped groove, and the yarn guide tube is provided with a limiting pin that extends into the arc-shaped groove.

[0010] Furthermore, the drive assembly includes a movable seat movably disposed on the mounting base and a drive rod provided on the movable seat. The adjustment cover has a slot, and the drive rod extends into the slot and abuts against the adjustment cover.

[0011] Furthermore, the mounting base is provided with a plurality of yarn guide cylinders at intervals along the moving direction of the movable seat, and the movable seat is provided with a plurality of drive rods at intervals along the moving direction of the movable seat, and the drive rods correspond one-to-one with the slots on each of the adjusting covers.

[0012] Furthermore, the drive assembly also includes an adjusting screw rotatably mounted on the mounting base, the axial direction of the adjusting screw being consistent with the moving direction of the movable seat, and the movable seat having a threaded hole that mates with the adjusting screw.

[0016] Compared with the prior art, this utility model has the following advantages: By using multiple movable blocks on the yarn guide cylinder to adjust the area of ​​the opening of the yarn passage hole, the yarn passes through the area enclosed by the multiple blocks after passing through the yarn passage hole. When the adjusting cover is rotated under the drive component, it pushes the guide rod to move in the through groove, causing the blocks to move in the sliding groove and increasing or decreasing the area covered by the blocks on the yarn passage hole. This changes the size of the area enclosed by the multiple blocks and limits the yarn by adjusting the position of the blocks to match the thickness of the yarn. This ensures that the yarn can pass through the yarn passage hole while preventing the yarn from shaking in the yarn guide cylinder. It solves the technical problem that the existing guiding device cannot adapt to yarns of different thicknesses, and produces the technical effect of being able to adjust according to the thickness of the yarn and meet the needs of production using yarns of different thicknesses. Moreover, the adjustment operation is simple and highly versatile. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a yarn guiding device for guiding yarns during the textile production process to ensure that the yarns are fed in an orderly manner.

[0021] Please refer to Figure 1 and Figure 2The yarn guiding device includes a mounting base 1, on which a yarn guide cylinder 2 is provided, and the yarn guide cylinder 2 has a yarn passage hole 21. When the yarn is guided by the yarn guiding device, the yarn passes through the yarn passage hole 21. The yarn guide cylinder 2 is provided with at least three grooves 22 at equal intervals along the circumference of the yarn passage hole 21, and each groove 22 is provided with a movable stop 3. The length direction of the groove 22 is perpendicular to the radial direction of the yarn passage hole 21. Any two adjacent stops 3 are in contact with each other and the stops 3 cover the yarn passage hole 21. As the stops 3 move along the groove 22, the area of ​​the stops 3 covering the yarn passage hole 21 increases or decreases. Since the yarn extends into the area enclosed by the stops 3 after passing through the yarn passage hole 21, the area enclosed by the stops 3 can be adjusted by moving the stops 3 in the groove 22, and the yarn can be limited by the stops 3. The yarn guide device is positioned to match the thickness of the yarn. A rotatable adjusting cover 4 is fitted on the yarn guide cylinder 2, and a drive assembly 5 connected to the adjusting cover 4 is provided on the mounting base 1. The stop block 3 is located between the yarn guide cylinder 2 and the adjusting cover 4. The adjusting cover 4 has a through hole 41 concentric with the yarn passage hole 21. The adjusting cover 4 has multiple through grooves 42 evenly spaced along the circumference of the through hole 41, and the number of through grooves 42 is the same as the number of stop blocks 3. Each stop block 3 is provided with a guide rod 31, which extends into the through groove 42 and abuts against the adjusting cover 4. When the adjusting cover 4 rotates under the drive assembly 5, the adjusting cover 4 pushes the guide rod 31 to move in the through groove 42 and drives the stop block 3 to move in the slide groove 22, thereby adjusting the position of the stop block 3 on the yarn guide cylinder 2.

[0022] Specifically, the operation steps for guiding the yarn using the yarn guiding device provided in this embodiment are as follows: First, the yarn is passed through the area enclosed by the yarn passage hole 21 and the multiple stops 3. Then, the driving component 5 is operated to rotate the adjusting cover 4 and push the stops 3 to move within the slide groove 22 until the size of the area enclosed by the stops 3 matches the thickness of the yarn passage hole 21. This limits the yarn position, ensuring stability during transport. The yarn guiding device provided in this embodiment limits the yarn position using the stops 3 and adjusts the area covered by the stops 3 within the slide groove 22 to match the yarn thickness. This ensures the yarn can pass through the yarn passage hole 21 while preventing it from swaying in the yarn guide cylinder 2, thus meeting the production needs of yarns with different thicknesses. Furthermore, the adjustment operation is simple and highly versatile.

[0023] like Figure 2As shown, the yarn guide cylinder 2 is also provided with a buffer washer 23, which is located inside the yarn passage hole 21 and covers the inner wall of the yarn passage hole 21. The buffer washer 23 is made of elastic silicone or rubber material. The use of the buffer washer 23 to cover the inner wall of the yarn passage hole 21 makes the inner wall of the yarn passage hole 21 soft, so as to prevent the yarn from being damaged by friction with the yarn guide cylinder 2 during the conveying process.

[0024] In detail, each of the stop blocks 3 is provided with a buffer pad 32, and the buffer pads 32 on each of the stop blocks 3 are arranged in a ring. The buffer pads 32 on the stop blocks 3 form an area for the yarn to pass through. The buffer pads 32 are made of elastic silicone or rubber material to prevent the yarn from abutting and rubbing against the edge of the stop block 3, which would cause damage or even breakage to the surface of the yarn.

[0025] like Figure 1 and Figure 2 As shown, the adjusting cover 4 is provided with an arc-shaped groove 43, and the yarn guide 2 is provided with a limiting pin 24, which extends into the arc-shaped groove 43. The cooperation between the limiting pin 24 and the arc-shaped groove 43 restricts the direction and stroke of the adjusting cover 4 on the yarn guide 2, and keeps the adjusting cover 4 on the yarn guide 2, which helps to improve the stability of the cooperation between the adjusting cover 4 and the yarn guide 2.

[0026] Please combine Figure 1 and Figure 3 The driving assembly 5 includes a movable seat 51 movably mounted on the mounting base 1, and a driving rod 52 is provided on the movable seat 51. The adjusting cover 4 has a slot 44, and the driving rod 52 extends into the slot 44 and abuts against the adjusting cover 4. When the movable seat 51 moves on the mounting base 1, the driving rod 52 pushes the adjusting rod to rotate on the yarn guide cylinder 2. At the same time, the driving rod 52 slides in the slot 44 to ensure that the adjusting cover 4 can move smoothly and to ensure stable operation of the yarn guiding device during adjustment.

[0027] In this embodiment, a plurality of yarn guide cylinders 2 are spaced apart on the mounting base 1 along the moving direction of the movable seat 51, and a plurality of drive rods 52 are spaced apart on the movable seat 51 along the moving direction of the movable seat 51, with each drive rod 52 corresponding to a slot 44 on each adjusting cover 4. The arrangement of multiple yarn guide cylinders 2 on the mounting base 1 enables the yarn guiding device to simultaneously guide multiple yarns for transport, and the stops 3 on the multiple guide cylinders can be adjusted simultaneously via the movable seat 51, which helps improve the adjustment efficiency of the yarn guiding device.

[0028] Please refer to Figure 3The drive assembly 5 further includes an adjusting screw 53 rotatably mounted on the mounting base 1. The axial direction of the adjusting screw 53 is consistent with the moving direction of the movable seat 51, and the movable seat 51 is provided with a threaded hole that mates with the adjusting screw 53. When the adjusting screw 53 is rotated, the engagement of the threaded hole with the adjusting screw 53 drives the movable seat 51 to move along the axial direction of the adjusting screw 53 and drives the adjusting cover 4 to rotate, thereby adjusting the position of the stop block 3 on the yarn guide cylinder 2. At the same time, when the adjusting screw 53 remains stationary, the engagement of the threaded hole with the adjusting screw 53 can lock the position of the movable seat 51, preventing the stop block 3 from moving unexpectedly during the yarn guiding process, thus making the yarn guiding device more reliable.

[0029] Specifically, the drive assembly 5 further includes a handwheel 54, which is fixedly connected to one end of the adjusting screw 53. The handwheel 54, fixedly connected to the end of the adjusting screw 53, facilitates rotation of the adjusting screw 53 to adjust the position of the stop block 3.

[0030] like Figure 1 As shown, the mounting base 1 is also provided with a mounting frame 11, which is located directly above the yarn guide cylinder 2 and has a rotatable yarn guide wheel 12. The yarn guide wheel 12 is used to abut against the yarn passing through the area enclosed by the yarn guide hole 21 and the stop block 3, so that the yarn remains taut during the conveying process and avoids the yarn from getting tangled on the yarn guide device or multiple yarns getting tangled together.

[0031] In detail, the yarn guide wheel 12 is provided with a yarn passage groove 13, which surrounds the side wall of the yarn guide wheel 12. The yarn passage groove 13 on the yarn guide wheel 12 is used to accommodate yarn, which helps to improve the stability of the fit between the yarn and the yarn guide wheel 12 and prevents the yarn from detaching from the yarn guide wheel 12 during the conveying process.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
