Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a yarn tensioning device and adjustment method for yarn spinning. Background Technology

[0002] Yarn tension plays a crucial role in the spinning process. Appropriate yarn tension maintains spinning stability, ensuring the yarn doesn't break or form defects during processing. If the yarn tension is too high, it may break due to excessive tensile force, leading to production interruptions and a decline in yarn quality. Conversely, if the yarn tension is too low, the yarn may be too loose, easily forming defects, similarly affecting yarn quality and yield. Therefore, during yarn spinning, the yarn is usually passed sequentially through corresponding holes in a tensioning device to adjust its tension. However, the process of connecting the yarn to the tensioning device and passing it through the holes is time-consuming, making yarn tension adjustment inconvenient.

[0003] Patent document CN110371783B discloses a variable-direction yarn spinning operation guiding tensioning device and method, including a base plate, a variable-direction pulley rod, an annular groove, a connecting column, a connecting plate, an anti-loosening device, and a rotating plate. The base plate has an annular groove connected to the variable-direction pulley rod via a sliding fit. A connecting column is installed in the middle of the base plate, positioned between two variable-direction pulley rods. A connecting plate is installed at the upper end of the connecting column, and anti-loosening devices are evenly distributed along its circumference. A rotating plate is located at the upper end of the connecting plate. The anti-loosening device synchronously expands the yarn, thereby changing the yarn winding length and keeping the yarn in a taut state. The position of the two variable-direction pulley rods is adjusted to change the yarn's conveying direction, reducing the friction generated during yarn deflection and decreasing yarn wear. However, this patent still has the following problems in actual use:

[0004] This tensioning device connects the yarn to the device by passing the yarn through the gap in the middle of the arc-shaped frame in sequence. This connection process is time-consuming, resulting in low efficiency in adjusting the yarn tension and affecting the efficiency of yarn spinning. In addition, during the adjustment process, when the yarn tension is too high, the tensioning device is unable to buffer the yarn tension, which makes the yarn prone to breakage during adjustment.

[0005] Therefore, we propose a yarn tensioning device and adjustment method for yarn spinning to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a yarn tensioning device and adjustment method for yarn spinning, in order to solve the problem that the current tensioning device connects the yarn to the tensioning device by passing the yarn sequentially through the gap in the middle of the arc frame, which results in a time-consuming connection process, low efficiency in yarn tension adjustment, and impact on yarn spinning efficiency. Furthermore, during adjustment, when the yarn tension is too high, the tensioning device is unable to buffer the yarn tension, leading to a tendency for the yarn to break during adjustment.

[0015] By adopting the above technical solution, the positioning of the pressing plate and the connecting seat is facilitated.

[0016] Preferably, the fixing seat is centrally symmetrically fixedly connected to the top surface of the base, and the outer side of the fixing seat is slidably connected to the middle of the moving groove.

[0017] By adopting the above technical solution, it is easy to reset the connector.

[0018] Preferably, the tensioning assembly is arranged in a centrally symmetrical manner, the fixed shaft is fixedly connected to the top of the connecting seat near the positioning groove, the middle of the connecting groove is slidably connected to the bottom ends of the two sets of tensioning wheels, and the support seat is located in the middle of the two sets of tensioning wheels.

[0019] By adopting the above technical solution, it is easier for textile yarns to fall off.

[0020] Preferably, the sliding groove is formed on one side of the connecting seat near the pressing plate, the end of the threaded rod away from the pressing plate is rotatably connected to the middle of the sliding groove, and the end of the threaded rod near the pressing plate passes through the connecting seat and is connected to a handwheel.

[0021] By adopting the above technical solution, the positioning of the threaded rod is facilitated.

[0022] Preferably, a relief groove is provided on one side of the threaded rod, a telescopic spring is fixedly connected in the middle of the relief groove, a locking block is fixedly connected to one end of the telescopic spring, and a locking groove is provided on the inner side of the sliding groove near the pressing plate, and the locking block overlaps with the locking groove.

[0023] By adopting the above technical solution, the positioning of the card block is facilitated.

[0024] Preferably, the relief groove is formed on the side of the threaded rod near the pressing plate, and the locking block is slidably connected to the middle of the relief groove.

[0025] By adopting the above technical solution, the positioning of the card block is facilitated.

[0026] A yarn tensioning device and adjustment method for yarn spinning, the steps of which are as follows:

[0027] Step 1: Align the yarn with the guide groove so that it falls into the guide groove. Press the limiting block to push the limiting spring to contract in the limiting groove inside the guide seat, so that the guide groove is fully exposed. This allows the yarn to enter the guide ring through the guide groove, thus positioning the yarn and reducing the need to pass the yarn through the hole. This makes it easier to adjust the yarn tension. At this time, the limiting block resets and seals the lower end of the guide groove to prevent the yarn from separating from the guide ring and to prevent the lower end of the guide groove from causing wear on the yarn, thereby improving the yarn guiding stability.

[0028] Step 2: By pressing the pressing plates on both sides of the base and retracting them towards the center, the pressing plates push the connecting seats at both ends to move. At this time, the moving groove on one side of the connecting seat slides on the fixed seat through the moving rod, and the return spring retracts, thus guiding the movement direction of the connecting seat. Simultaneously, the positioning block pushes the positioning spring to retract into the retraction groove, causing the positioning block to separate from the positioning groove. At this time, the connecting seat drives the tensioning wheel at the end of the fixed rotating rod to move in the direction of the connecting seat's movement through the fixed shaft, causing the two intersecting tensioning wheels to unfold and the connecting groove below the tensioning wheels to rotate. Subsequently, the two tensioning wheels fall on both sides of the center line with the two guide rings as endpoints, making the gap between the guide rings and the tensioning wheels form a straight line, which facilitates the installation of the yarn in the tensioning wheels by pressing directly. The support seat in the middle of the tensioning wheel supports the yarn and prevents the yarn from falling out of the middle of the tensioning wheel.

[0029] Step 3: Align one end of the yarn that has passed through the middle of the tensioning wheel with the guide groove again, and complete the connection between the yarn and the tensioning device by pressing the limiting block. Then, when the pressing plate is released, the connecting seat is reset by the action of the return spring pushing the fixed seat, and the positioning block is engaged with the positioning groove to form a positioning. At the same time, the tensioning wheel is reset, forming a staggered effect, so that the yarn is taut.

[0030] Step 4: Rotate the threaded rod to cause the locking block on the outside of the threaded rod to push the telescopic spring into the relief groove, separating the locking block from the groove. After one rotation, the locking block and groove re-engage. This allows for recording the number of rotations of the threaded rod, facilitating uniform tension adjustment during yarn weaving. Simultaneously, the threaded rod drives the moving shaft to slide in the sliding groove, causing the moving shaft to drive the sliding rotating rod to rotate at the sliding shaft. At this time, the fixed rotating rod rotates at the fixed shaft, thereby adjusting the offset position of the tensioning wheel at the end of the fixed rotating rod, thus adjusting the yarn tension. When the yarn tension is too high, the yarn will push the tensioning wheel to contract towards the center. At this time, the fixed rotating rod pushes the buffer plate to slide in the buffer groove through the sliding shaft, and the buffer spring buffers the tension, reducing the possibility of yarn breakage.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up the guide component and the moving component, the yarn can quickly pass through the guide ring and the tensioning wheel, greatly shortening the time spent connecting the yarn to the tensioning device. Furthermore, the rapid reset of the tensioning wheel allows for rapid adjustment of the yarn tension, improving the efficiency of yarn spinning. The buffer plate and buffer spring reduce yarn breakage when the yarn tension is too high. The use of locking blocks, telescopic springs, and locking grooves facilitates unified adjustment of the tensioning device. The specific details are as follows:

[0032] 1. By setting up the guide component and the moving component, when adjusting the yarn tension, a gap is formed between the tensioning wheels by pressing the limit block and the pressing plate, so that the yarn can quickly pass through the guide ring and the tensioning wheel. This avoids the process of the yarn weaving through the hole, greatly shortening the time spent connecting the yarn to the tensioning device when adjusting the yarn tension. When the pressing plate is released, the tensioning wheel quickly resets, so as to quickly adjust the yarn tension. This facilitates the yarn to enter the textile work quickly and improves the efficiency of yarn spinning.

[0033] 2. By rotating the threaded rod to control the angle between the sliding rod and the fixed rod, the position of the tensioning wheel can be adjusted, thereby achieving the effect of adjusting the yarn tension. At the same time, the setting of the buffer plate and buffer spring facilitates the buffering of tension when the yarn tension is too high during tension adjustment, thereby reducing the possibility of yarn breakage and making it easier to observe the tension status, thus facilitating timely adjustment of the tension.

[0034] 3. By setting a locking block, a telescopic spring, and a locking groove on the outside of the threaded rod, the number of rotations of the threaded rod can be counted by the sound or resistance when the locking block and the locking groove engage, thus facilitating the uniform adjustment of the tensioning device.

The bottom surfaces of the pressing plate 301 and the connecting seat 305 are... The top surface of the base 1 is slidably connected.

[0048] Among them, a tensioning component 4 is installed on one side of the moving component 3. The tensioning component 4 includes a fixed shaft 401, a fixed rotating rod 402 rotatably connected to the outer side of the fixed shaft 401, a sliding shaft 406 rotatably connected to the middle of the fixed rotating rod 402, a sliding rotating rod 410 provided at the upper end of the sliding shaft 406, a buffer groove 403 opened at the end of the sliding rotating rod 410 near the sliding shaft 406, the middle of the sliding shaft 406 and the buffer groove 403 are slidably connected, and a buffer plate 404 is slidably connected to the middle of the buffer groove 403.

The lower end of the tensioning wheel 407 passes through the fixed rotating rod 402 and is slidably connected to a... A connecting groove 408 has a support base 409 fixedly connected to the middle of its top surface. The tensioning assembly 4 is centrally symmetrically arranged. A fixed shaft 401 is fixedly connected to the top of the connecting base 305 near the positioning groove 310. The middle of the connecting groove 408 is slidably connected to the bottom ends of two sets of tensioning wheels 407. The support base 409 is located between the two sets of tensioning wheels 407. A sliding groove 412 is formed on the side of the connecting base 305 near the pressing plate 301. The end of the threaded rod 413 away from the pressing plate 301 is connected to the sliding groove 412. The intermediate rotating connection has a threaded rod 413 with one end near the pressing plate 301 passing through the connecting seat 305 and connected to a handwheel. The tension can be adjusted by changing the angle between the fixed rotating rod 402 and the sliding rotating rod 410. The buffer spring 405 and the buffer plate 404 at the end of the sliding rotating rod 410 away from the moving shaft 411 facilitate the tension wheel 407 to contract towards the center when the yarn tension adjustment causes excessive tension, thus achieving a buffering effect and reducing the possibility of yarn breakage.

[0049] A clearance groove 414 is provided on one side of the threaded rod 413. A telescopic spring 415 is fixedly connected in the middle of the clearance groove 414. A locking block 416 is fixedly connected to one end of the telescopic spring 415. A locking groove 417 is provided on the inner side of the sliding groove 412 near the end of the pressing plate 301. The locking block 416 overlaps with the locking groove 417. The clearance groove 414 is provided on the side of the threaded rod 413 near the pressing plate 301. The locking block 416 is slidably connected to the middle of the clearance groove 414. The sound or resistance generated by the locking block 416 and the locking groove 417 when the threaded rod 413 rotates once facilitates the counting of the number of rotations of the threaded rod 413, thereby facilitating the uniform adjustment of the yarn tension.

[0050] Working principle: such as Figures 1-9As shown, when using this device, firstly, by passing the yarn through the guide groove 206, and by pressing the limiting block 204 to push the limiting spring 203 to contract in the limiting groove 202 inside the guide seat 201, the yarn passes through the guide groove 206 and enters the guide ring 205. Then, the limiting block 204 resets, closing the lower end of the guide groove 206. Finally, by pressing the pressing plates 301 on both sides of the base 1 towards the center, the connecting seat 305 moves. At this time, the moving rod 307 in the moving groove 306... The fixed seat 309 slides on the wall, causing the return spring 308 to retract. At the same time, the positioning block 304 pushes the positioning spring 303 to retract into the shrinkage groove 302, causing the positioning block 304 to separate from the positioning groove 310. At this time, the tension wheel 407 at the end of the fixed rotating rod 402 moves with the connecting seat 305, so that the gap between the guide ring 205 and the tension wheel 407 forms a straight line, realizing the installation of the yarn in the tension wheel 407. The support seat 409 in the middle of the connecting groove 408 supports the yarn.

[0051] Next, one end of the yarn passing through the tension wheel 407 is connected to the guide ring 205 at the other end. Then, when the pressing plate 301 is released, the connecting seat 305 is reset under the action of the return spring 308 pushing the fixed seat 309, and the positioning block 304 is engaged with the positioning groove 310 to form a positioning. At the same time, the tension wheel 407 is reset, so that the yarn is taut.

[0052] Finally, by rotating the threaded rod 413, the locking block 416 pushes the telescopic spring 415 to retract into the relief groove 414, causing the locking block 416 to separate from the groove 417. After rotating one revolution, the locking block 416 and the groove 417 re-engage. At the same time, the threaded rod 413 drives the moving shaft 411 to slide in the sliding groove 412, so that the moving shaft 411 drives the sliding rotating rod 410 to rotate at the sliding shaft 406. At this time, the fixed rotating rod 402 rotates at the fixed shaft 401, thereby adjusting the offset position of the tensioning wheel 407 at the end of the fixed rotating rod 402. When the yarn tension is too high, the yarn will push the tensioning wheel 407 to contract towards the middle. At this time, the fixed rotating rod 402 pushes the buffer plate 404 to slide in the buffer groove 403 through the sliding shaft 406, and the tension is buffered by the buffer spring 405.

A telescopic spring (415) is fixedly connected in the middle of the relief groove (414). A locking block (416) is fixedly connected to one end of the telescopic spring (415). A locking groove (417) is provided on the inner side of the sliding groove (412) near the end of the pressing plate (301). The locking block (416) overlaps with the locking groove (417).

9. The method for adjusting a yarn tensioning device for yarn spinning according to claim 8, characterized in that, The usage steps are as follows: Step 1: Align the yarn with the guide groove (206) so that the yarn falls into the guide groove (206). Press the limiting block (204) to push the limiting spring (203) to contract in the limiting groove (202) inside the guide seat (201), so that the guide groove (206) is fully exposed. This allows the yarn to enter the guide ring (205) through the guide groove (206), thereby positioning the yarn and reducing the steps of passing the yarn through the hole. This makes it easier to adjust the yarn tension. At this time, the limiting block (204) resets and closes the lower end of the guide groove (206) to prevent the yarn from separating from the guide ring (205) through the guide groove (206). It also prevents the lower end of the guide groove (206) from causing wear on the yarn, thereby improving the yarn guiding stability. Step 2: By pressing the pressing plates (301) on both sides of the base (1) and retracting them towards the center, the pressing plates (301) push the connecting seats (305) at both ends to move. At this time, the moving groove (306) on one side of the connecting seat (305) slides on the fixed seat (309) through the moving rod (307), and causes the return spring (308) to retract, thereby guiding the moving direction of the connecting seat (305). At the same time, the positioning block (304) pushes the positioning spring (303) to retract into the retraction groove (302), causing the positioning block (304) to separate from the positioning groove (310). At this time, the connecting seat (305) drives the fixed rotation through the fixed shaft (401). The tensioning wheel (407) at the end of the rod (402) moves in the direction of the connecting seat (305), causing the two intersecting tensioning wheels (407) to unfold and the connecting groove (408) below the tensioning wheel (407) to rotate. Then the two tensioning wheels (407) fall on both sides of the center line with the two guide rings (205) as the endpoints, so that the gap between the guide ring (205) and the tensioning wheel (407) forms a straight line, which facilitates the installation of the yarn in the tensioning wheel (407) by pressing directly. The support seat (409) in the middle of the tensioning wheel (407) supports the yarn and prevents the yarn from falling off from the middle of the tensioning wheel (407). Step 3: Align one end of the yarn passing through the tensioning wheel (407) with the guide groove (206) again, and complete the connection between the yarn and the tensioning device by pressing the limiting block (204). Then, when the pressing plate (301) is released, the connecting seat (305) is reset under the action of the return spring (308) pushing the fixed seat (309), and the positioning block (304) is engaged with the positioning groove (310) to form a positioning. At the same time, the tensioning wheel (407) is reset, forming a staggered effect, so that the yarn is tightened. Step 4: Rotate the threaded rod (413) to push the telescopic spring (415) into the relief groove (414) by the locking block (416) on the outside of the threaded rod (413). This causes the locking block (416) to separate from the groove (417). After rotating one revolution, the locking block (416) and groove (417) re-engage, recording the number of rotations of the threaded rod (413) for easy adjustment of tension during yarn weaving. At the same time, the threaded rod (413) drives the moving shaft (411) to slide in the sliding groove (412), enabling the moving shaft (411) to drive the sliding rotating rod. (410) Rotate at the sliding shaft (406), at which time the fixed rotating rod (402) rotates at the fixed shaft (401), thereby adjusting the offset position of the tension wheel (407) at the end of the fixed rotating rod (402) to adjust the yarn tension. When the yarn tension is too high, the yarn will push the tension wheel (407) to contract in the middle. At this time, the fixed rotating rod (402) pushes the buffer plate (404) to slide in the buffer groove (403) through the sliding shaft (406), and the tension is buffered by the buffer spring (405) to reduce the occurrence of yarn breakage.
