Description

Technical Field

[0001] This utility model relates to the field of yarn generation technology, and in particular to a yarn feeding untwisting device. Background Technology

[0002] In the textile processing industry, yarn untwisting is a key pre-weaving treatment process, and traditional untwisting devices generally have the following problems:

[0003] Insufficient structural stability: Most equipment uses a single-point supported rotating disc structure, and yarn tension fluctuations can easily cause the rotating disc to wobble, affecting the uniformity of untwisting.

[0004] Low adjustment efficiency: The sliding modules are mostly fixed by bolts, and the position adjustment requires manually tightening and loosening the bolts, which cannot achieve quick adaptation to different yarn specifications;

[0005] Defects in untwisting force adjustment: There is a lack of adjustability between the rotating disc and the support column, making it difficult to quickly adjust the yarn untwisting effect during use.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a yarn feeder untwisting device that would have greater industrial application value. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a yarn feeder untwisting device.

[0008] This utility model discloses a yarn feeding untwisting device, which includes a supporting body. One side of the body is a vertically upward plate. The upper end of the plate has a first through hole for yarn to pass through. The end face of the plate has a winding column arranged parallel to the upper surface of the body. The end of the winding column has a rotatable rotating disk. The outer ring of the rotating disk has a second through hole for yarn to pass through.

[0009] This yarn feeder untwisting device is supported by a main body. A vertically upward-facing plate is provided on one side of the main body. A first through hole is opened at the upper end of the plate for the yarn to pass through. A winding column parallel to the upper surface of the main body is installed on the end face of the plate. A rotatable rotating disk is installed at the end of the winding column. A second through hole is opened on the outer ring of the rotating disk for the yarn to pass through. This structure forms a stable support through the main body and the plate. The first and second through holes are used to guide the yarn. The rotating disk works with the winding column to complete the yarn untwisting operation.

[0010] Furthermore, the lower part of the main body is a sliding block for installation. The middle part of the sliding block is hollow and is used to fit onto the sliding rod.

[0011] The main body has a sliding block for installation at the bottom. The middle of the sliding block is designed to be hollow, so it can be directly fitted onto the slide rod for installation. The hollow structure of the sliding block enables the main body to move flexibly and adjust its position on the slide rod.

[0012] Furthermore, there is a recessed guide groove on the inner side of the bottom of the sliding block.

[0013] The bottom inner side of the sliding block is provided with a recessed guide groove. This guide groove precisely matches the contour of the guide rail through its concave structure, ensuring that the sliding block achieves bidirectional limiting when moving along the slide rod.

[0014] Furthermore, there is a groove on the inner side of the top of the sliding block, and one side of the groove is a raised positioning block.

[0015] The sliding block has a groove on the inner side of its top, and a protruding positioning block is provided on one side of the groove. The smooth movement of the sliding block is achieved through the precise cooperation between the groove and the matching guide rail.

[0016] Furthermore, the winding column includes a mounting column fixed to the upright plate. The outer side of the mounting column is fitted with a rotating sleeve, the end of which is fixedly connected to the rotating disk. The inside of the mounting column is hollow. After the mounting bolt is inserted into the mounting column, it extends out of the mounting column. The end of the mounting bolt passes through the rotating disk and is fixed by a locking nut.

[0017] The winding column consists of a mounting column, a rotating sleeve, mounting bolts, and a locking nut. The mounting column is fixed to the upright plate and has a hollow internal structure. The rotating sleeve is fitted on the outside of the mounting column and is fixed to the rotating disk at its end. The mounting bolts are inserted into the inner cavity of the mounting column and pass through the rotating disk, and are finally locked and fixed by the locking nut. This structure enables the rotating sleeve to rotate stably around the mounting column, while the bolt preload ensures the axial positioning reliability of the rotating disk and the winding column.

[0018] Furthermore, a spring is installed between the protrusion at the tail end of the mounting bolt and the inner end face of the mounting post. The spring pushes the mounting bolt back to its original position.

[0019] A return spring is installed between the protrusion at the tail end of the mounting bolt and the inner end face of the mounting column. When the mounting bolt is compressed, the spring stores energy and pushes the mounting bolt axially back to the initial position through elastic restoring force, realizing the automatic reset function. At the same time, the spring preload can adjust the fit clearance between the mounting bolt and the locking nut to ensure that the axial clearance of the rotating sleeve is controlled within the design range. This structure simplifies the manual operation process and improves the equipment maintenance efficiency.

[0020] Furthermore, the end of the mounting column has evenly spaced limiting blocks, with slots between adjacent limiting blocks, and the inner side of the rotating disk has locking blocks that cooperate with the slots.

[0021] Limiting blocks are evenly distributed around the circumference at the end of the mounting column, and equal-angle slots are formed between adjacent limiting blocks. The corresponding locking blocks on the inner side of the rotating disk can precisely engage with the slots. This structure realizes the indexing and positioning function of the rotating disk through the periodic cooperation of the locking blocks and slots. The limiting blocks not only provide mechanical stop protection, but also ensure the angular repeatability accuracy of the rotating disk when it stops at each station. The whole structure constitutes a reliable circumferential positioning system.

[0022] Furthermore, a circular limiting plate is fixed on the upright plate.

[0023] As a key component of the yarn feeding system, the limiting disc's circular structure effectively suppresses the disorderly jumping of the yarn during the dynamic feeding process through rigid blocking. When the yarn is drawn out from the winding post, the physical barrier formed by the edge of the limiting disc can block the radial displacement of the yarn caused by inertia or vibration, preventing the yarn from winding back to the non-target area of ​​the winding post.

[0024] By means of the above-described solution, the present invention has at least the following advantages:

[0025] 1. Enhance structural stability:

[0026] The rigid support frame formed by the main body and the upright plate, combined with the indexing and positioning structure (limiting block / slot / block) of the rotating disk and the winding column, effectively suppresses the sway of the rotating disk caused by yarn tension fluctuations, ensuring that there is no radial movement during the untwisting process;

[0027] The spring preload mechanism at the tail end of the mounting bolt automatically adjusts the axial clearance, eliminating axial loosening during the operation of the rotating sleeve and improving dynamic stability.

[0028] 2. Achieve rapid and precise adjustment:

[0029] The hollow design of the sliding block, combined with the sunken guide groove and the top sliding groove / positioning block, supports stepless sliding and bidirectional locking along the sliding rod. The main body position can be quickly adjusted without tightening or loosening bolts, adapting to different yarn specifications.

[0030] The physical barrier formed by the limit plate prevents the yarn from jumping and winding back, avoiding machine stoppage for adjustment and improving continuous operation efficiency.

[0031] 3. Optimize untwisting force control:

[0032] The rotary disc indexing and positioning structure provides a multi-position locking function (block engagement groove), which can precisely control the number of yarn untwisting turns and tension by changing the dwell angle of the rotary disc;

[0033] The locking nut, in conjunction with the spring preload, enables linear fine-tuning of rotational resistance, meeting differentiated untwisting strength requirements.

[0034] 4. Reduce maintenance costs and failure rate:

[0035] The reset spring drives the mounting bolts to automatically return to their original position, simplifying the disassembly and maintenance process.

[0036] The limit plate effectively prevents yarn from winding back onto the column, reducing the yarn breakage and jamming accident rate by more than 70% (actual measurement data), and extending the equipment life.

[0046] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0047] See Figure 1 When the yarn feeder untwisting device is working, the yarn passes through the second through hole 6 on the outer ring of the rotating disk 5 and the first through hole 3 at the upper end of the vertical plate 2 in sequence. When the yarn is drawn out from the winding column 4, the rotation of the rotating disk 5 generates an untwisting effect. A stable support structure is formed by the main body 1 and the vertical plate 2. The first through hole 3 and the second through hole 6 achieve precise yarn guidance. The rotatable rotating disk 5 ensures that the untwisting action is smooth and continuous. The overall structure is simple and reliable, and can effectively improve the uniformity of yarn untwisting and production efficiency.

[0048] See Figure 1 and Figure 2 The yarn feeder untwisting device is installed on the slide rod via a hollow sliding block 7 located below the main body 1. During operation, the sliding block 7 can move flexibly along the slide rod to adjust the overall position of the untwisting device. The hollow structure design makes installation and position adjustment more convenient, and the overall position of the device can be quickly adjusted without disassembly. At the same time, the tight cooperation between the sliding block 7 and the slide rod ensures the stability of the device during operation and effectively avoids positional deviation during the untwisting process.

[0049] The sliding block 7 has a recessed guide groove 8 on its inner bottom side. During operation, the guide groove 8 and the slide rod are precisely matched to ensure that the sliding block 7 moves along the slide rod with a stable trajectory without deviation. The recessed guide groove 8 design enhances the contact area and guiding accuracy between the sliding block 7 and the slide rod, effectively preventing shaking and position drift during equipment operation.

[0050] See Figure 1 The sliding block 7 has a combination structure of sliding groove 9 and positioning block 10 on the top inner side. During operation, the sliding groove 9 and the equipment frame guide rail are precisely matched to achieve lateral sliding. The positioning block 10 is quickly positioned by being inserted into the preset groove. The sliding groove guide rail system ensures that the equipment moves smoothly and reduces vibration interference during the yarn untwisting process. The raised positioning block design realizes one-click precise positioning and avoids errors caused by manual adjustment.

[0051] See Figure 4The winding column 4 of this yarn feeder untwisting device adopts a combination structure of hollow mounting column 11 and rotating sleeve 12. The mounting column 11 is fixedly connected to the vertical plate 2. The hollow structure inside the mounting column 11 is inserted with mounting bolt 13. The end of the mounting bolt 13 and the rotating disk 5 are fixed by locking nut 14. During operation, the rotating disk 5 is manually rotated to drive the rotating sleeve 12 to rotate stably around the mounting column 11, so that the introduced yarn is wound on the surface of the rotating sleeve 12. Then, the yarn is untwisted by the yarn feeding operation. The hollow mounting column 11 design reduces the overall weight and facilitates the mounting bolt 13 to install the rotating disk 5. The nested structure of the rotating sleeve 12 and the mounting column 11 ensures the coaxial accuracy of the rotating parts. The through-type mounting bolt 13 and the locking nut 14 achieve a triple fixing effect (vertical plate-mounting column-rotating disk), which not only ensures the structural rigidity during high-speed rotation, but also facilitates later maintenance through the detachable design, significantly improving the reliability and service life of the equipment.

[0052] See Figure 4 A spring (not shown in the figure) structure is added between the protrusion at the tail end of the mounting bolt 13 and the inner end face of the mounting column 11. During operation, the spring force automatically pushes the mounting bolt 13 back to its original position. The spring preload keeps the bolt in a stable tension state, effectively eliminating the loosening of the thread gap that may occur when the equipment is running at high speed.

[0053] See Figure 3 , Figure 5 and Figure 6 The end of the mounting column 11 is provided with a combination structure of equidistantly distributed limiting blocks 15 and slots 16. The locking block 17 on the inner side of the rotating disk 5 dynamically engages with the slot 16. During operation, the precise angle control of the rotating disk 5 is achieved by sliding the locking block 17 along the trajectory of the slot 16. The array of limiting blocks forms a multi-point mechanical stop, which effectively prevents the rotating disk from over-rotating or misaligning. The meshing design of the slot and the locking block not only ensures the transmission stability and eliminates the risk of slippage, but also achieves rapid angle adjustment of the yarn bobbin through modular positioning. Each slot corresponds to a fixed station, which significantly improves the repeatability positioning accuracy and production change efficiency of the untwisting process.

[0054] See Figure 1 The limiting disc 18 is fixed on the upright plate 2 in a static installation. Its core function is to form a physical barrier for the yarn through the annular disc. When the yarn is released from the rotating sleeve 12 during operation, the first through hole 3 also passes through the limiting disc 18. The first through hole 3 is directly used for the yarn to pass through. The circular limiting disc 18 increases the area of ​​blocking the yarn, effectively suppressing the phenomenon of back-winding and entanglement caused by yarn vibration during the yarn release process, especially for high elasticity or fine denier yarns.
