Description

Technical Field

[0001] This utility model relates to the field of winding device technology, specifically to a yarn winding device. Background Technology

[0002] In textile production, yarn winding is a crucial step connecting preceding and following processes, and its quality directly impacts subsequent processing efficiency and product quality. Yarn winding devices must orderly wind yarn onto a reel to form a neat yarn roll. Preventing yarn from scattering or loosening after winding and during transport is a core requirement for ensuring winding quality. Existing winding devices often use hinged fixed supports on the reel to limit yarn movement. These supports are located at both ends or on the outside of the reel. After winding, the supports are rotated onto the yarn roll, and the contact between the supports and the roll prevents yarn from detaching, avoiding increased costs and production interruptions caused by scattering. However, this structure's fixed support position relative to the reel cannot accommodate different winding amounts. In textile production, the yarn winding amount fluctuates greatly due to variations in processes, specifications, and requirements, causing changes in the yarn roll's radial dimension. With large winding amounts, excessively tight contact between the fixed supports can easily damage the yarn or even cause breakage; with small winding amounts, gaps appear between the supports and the roll, and the limiting mechanism fails, still leading to yarn scattering. Therefore, this utility model provides a yarn winding device. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0017] like Figure 1 As shown, a yarn winding device includes: a base 1, a plurality of support frames 2 are arranged sequentially on the base 1, and yarn guide rollers 3 are arranged on the support frames 2 to guide the yarn to be wound up.

[0018] A take-up roller holder 4 is provided on the base 1, and a take-up I-beam roller 5 is provided on the take-up roller holder 4. The take-up I-beam roller 5 includes a central round rod and two side round plates, forming an I-beam structure. When the take-up I-beam roller 5 is placed on the take-up roller holder 4, it can rotate under the drive of a motor to realize the winding of yarn.

[0019] like Figure 2 and Figure 3 As shown, at least one groove 6 is provided on each of the two side plates of the winding I-beam roll 5, running radially along the circular plate. The groove 6 has inwardly recessed sides forming sliding inner grooves. The groove 6 extends inward from the edge of the side plate of the winding I-beam roll 5. The sliding inner grooves are located within the side plate of the winding I-beam roll 5.

[0020] A rotating slider 7 is slidably disposed within the slide groove 6. Both ends of the rotating slider 7 are rotatably connected to a sliding block 8 slidably disposed within the inner sliding groove, and a fixed support arm 9 is fixedly connected to one side of the slider 7. The rotating slider 7 can both slide and rotate. The sliding block 8 can only slide.

[0021] like Figure 4 and Figure 5As shown, the top of the fixed support arm 9 is fixedly connected to the rotating slider 7. The width of its top segment is less than or equal to the width of the groove 6, while the width of the remaining segments is greater than the width of the groove 6. The length of the segment at the top of the fixed support arm 9, where the width is less than the width of the groove 6, is greater than or equal to the thickness of the winding I-beam roller 5. This is to ensure that the fixed support arm 9 rotates with the rotating slider 7. During rotation, the top of the fixed support arm 9 will intrude into the groove 6. To avoid interference, the width of the top of the fixed support arm 9 is less than or equal to the width of the groove 6. At the same time, the width of the remaining segments of the fixed support arm 9 is greater than the width of the groove 6, which limits the rotation range of the fixed support arm 9. It can rotate outwards to the point where it is in contact with the outer wall of the side plate of the winding I-beam roller 5, and inwards to the point where the end of the wider segment of the fixed support arm 9 abuts against the inner wall of the side plate of the winding I-beam roller 5. Furthermore, when the length of the segment at the top of the fixed support arm 9, where the width is less than the width of the groove 6, is equal to the thickness of the winding I-beam roller 5, the fixed support arm 9, when rotated inwards to its maximum value, is parallel to the axis of the winding I-beam roller 5. When rotating, the rotating slider 7 is located at the top of the slide groove 6 (edge ​​of the side plate).

[0022] The fixed support arm 9 is hollow inside and has an inner rod 10 that slides on it. The inner rod 10 extends from the opening at the bottom of the fixed support arm 9 to the outside of the fixed support arm 9. The inner rod 10 is telescopic to accommodate take-up I-beam rollers 5 of different lengths.

[0023] The bottom end of the inner rod 10 is always located outside the fixed support arm 9, and a connecting plate 11 is provided at its bottom end. A first permanent magnet is provided on the connecting plate 11. A positioning platform 12 is provided on the outer wall of the side plate of the winding I-beam roller 5, and a second permanent magnet is provided on the positioning platform 12 that attracts the first permanent magnet. When the fixed support arm 9 rotates to fit against the outer wall of the side plate of the winding I-beam roller 5, the top end of the inner rod 10 is magnetically attracted to the positioning platform 12 by the magnetic force of the permanent magnet, thus achieving fixation.

[0024] A lead screw 13 is installed inside the sliding inner groove. The lead screw 13 is threadedly engaged with the sliding block 8, and the top end of the lead screw 13 extends to the outside of the winding I-beam roller 5. A rotating handle 14 is installed at the top end of the lead screw 13. Rotating the handle 14 can drive the lead screw 13 to rotate, which can drive the sliding block 8 to rise and fall. The sliding block 8 can drive the rotating slider 7 and the fixed support arm 9 to rise and fall.

[0025] In this embodiment, there are two slide grooves 6, symmetrically arranged along the diameter of the winding I-beam roller 5, and the sliding inner grooves on both sides of the two slide grooves 6 are connected. The lead screw 13 is placed in the two connected sliding inner grooves and simultaneously engages with the sliding blocks 8 on the sides of the two rotating sliders 7, driving the two sliding blocks 8 to move synchronously in opposite directions. The two fixed support arms 9 can be raised and lowered simultaneously by one lead screw 13, making the structure simpler and the operation more convenient.

[0026] A lead screw 13 is installed in only one sliding groove, and a slide rod 15 is fixedly installed in the other sliding groove. The slide rod 15 is in sliding engagement with the sliding block 8. The slide rod 15 can improve the sliding stability of the sliding block 8, the rotating slider 7, and the fixed support arm 9.

[0027] The connecting plate 11 has through holes. When two connecting plates 11 are joined together, they are fixedly connected by bolts that fit in the through holes.

[0028] Working process: After the take-up I-beam roller 5 has finished winding, the operator separates the inner rod 10 from the positioning table 12, and then rotates the fixed support arm 9 so that it is parallel to the axis of the take-up I-beam roller 5; then, by rotating the handle 14, the fixed support arm 9 and the inner rod 10 are driven to descend until they are in contact with the surface of the wound yarn. The inner rod 10 is slid so that the ends of the two opposing inner rods 10 are magnetically connected together by permanent magnets. Then, bolts can be inserted as needed to improve the stability of the fixation.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
