Description

Technical Field

[0001] This utility model belongs to the field of textile technology, and in particular relates to a yarn tension adjustment device for textile processing. Background Technology

[0002] Textiles refer to products manufactured through spinning. Yarn is the main material used in textile production. Specifically, yarn is a thread-like material made from natural or synthetic fibers through a spinning process, possessing characteristics of flexibility and high luster. During the conveying process, yarn tension can become too loose or too tight. When the yarn tension is too tight, it can cause the yarn to break; when the yarn tension is too loose, it can cause the yarn to become tangled and uncoordinated. Both situations affect the normal conveying of the yarn. Therefore, a yarn tension regulating device is needed to adjust the yarn tension according to the actual situation.

[0003] A search revealed a yarn tension adjusting device for textile machinery in patent publication number CN222729201U. The device includes a support plate, a first motor fixedly connected to the upper surface of the support plate, a lead screw fixedly connected to the output end of the first motor, a slider threadedly connected to the outer surface of the lead screw, a connecting plate fixedly connected to the front surface of the slider, and a lifting block fixedly connected to the lower surface of the connecting plate. The first and second limiting plates effectively prevent the yarn from tangling during transport to the textile machinery, thus avoiding interference with yarn processing. The second motor, first guide post, and second guide post structure ensure that when the yarn comes into contact with the first and second guide posts, activating the second motor causes the first and second guide posts to rotate at a uniform speed, resulting in more stable yarn transport to the textile machinery.

[0004] However, yarn tension regulating devices used in textile processing still have the following shortcomings in actual use: 1. To facilitate simultaneous tension adjustment of multiple sets of yarns, multiple sets of guide wheels are fixed to the tension roller. While adjusting the position of the tension roller, the positions of multiple sets of guide wheels are adjusted, and the tension of multiple sets of yarns is adjusted at the same time. However, since the guide wheels are fixed to the tension roller, the number of guide wheels cannot be increased or decreased according to the number of yarns, which may result in insufficient or surplus guide wheels, and the guide wheels will not be fully utilized. 2. To prevent adjacent yarns from contacting and knotting during the guidance of multiple sets of guide wheels and to make the yarns move more smoothly, limit components are installed on the guide wheels to limit the movement trajectory of the yarns. However, the position of the limit components is fixed and cannot rotate, which increases the friction between the yarns and the limit components and causes wear on the yarns.

[0005] To address these issues, we provide a yarn tension regulating device for textile processing. Utility Model Content

[0006] The purpose of this utility model is to provide a yarn tension adjustment device for textile processing. By setting a guide component, the guide wheels can be easily added or removed according to the number of yarns, avoiding insufficient or surplus guide wheels and making full use of the guide wheels. By setting a limiting component, the movable ring prevents adjacent yarns from contacting and knotting. The movable ring also reduces the friction between the yarn and the movable ring, reducing yarn wear, thereby solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a yarn tension adjusting device for textile processing, comprising a mounting frame, inside which guide rollers are symmetrically fixed, and inside which tension rollers are movably connected, both guide rollers and tension rollers have grooves on their lower surfaces, and below each guide roller and tension roller is a guiding assembly, the guiding assembly including a sliding seat slidably connected inside the groove, the lower surface of the sliding seat being threaded with a screw, and below the sliding seat is a guide wheel, both sides of the guide wheel being rotatably connected with ear plates, the ear plates being fixed to the lower surface of the sliding seat; a limiting assembly is provided on the peripheral sidewall of the guide wheel, the limiting assembly including collars symmetrically sleeved on the peripheral sidewall of the guide wheel, a connecting ring rotatably connected to the sidewall of the collar, and a movable ring fixed to the sidewall of the connecting ring located away from the collar.

[0008] The present invention is further configured such that a base plate is fixedly connected to the lower surface of the mounting bracket, and ear seats are fixedly connected to the side wall of the base plate in a rectangular array, and the upper surface of the ear seats is provided with internal thread through holes for threaded connection bolts.

[0009] The present invention is further configured such that a through groove is provided on the side wall of the mounting bracket, and guide grooves are provided on both inner walls of the through groove. The ear blocks fixed to both ends of the tension roller are slidably connected inside the guide grooves, and the sliders symmetrically fixed to the two side walls of the ear blocks are slidably connected inside the guide grooves.

[0010] The present invention is further configured such that the motor mounted on the mounting bracket is located inside the through groove, and the lead screw connected to the output end of the motor has a threaded ball nut on its peripheral side wall, and the ball nut is interference-fitted onto one of the lugs.

[0011] The present invention is further configured such that the guide rod installed on the mounting bracket is located inside the through groove, and the upper end of the guide rod passes through another ear block.

[0012] The present invention is further configured such that the lower surface of the guide roller is symmetrically provided with notches, the lower surface of the tension roller is symmetrically provided with notches, and the notches are connected to the sliding groove.

[0013] The present invention is further configured such that the groove is a T-shaped groove structure and the sliding seat is a T-shaped structure.

[0014] This utility model has the following beneficial effects: 1. This utility model uses a guide component. By loosening the screw counterclockwise, the sliding seat is pushed and slides along the groove into the notch. After the sliding seat moves into the notch, it can be removed from the groove, thus disassembling the guide wheel and reducing the number of guide wheels. Conversely, the guide wheel can be installed to increase the number of guide wheels. This allows for easy adjustment of the number of guide wheels according to the amount of yarn, ensuring full utilization of the guide wheels and avoiding excess or shortage of guide wheels.

[0015] 2. This utility model sets a limiting component, and the movable ring limits the movement trajectory of the yarn, avoiding contact and knotting between adjacent yarns, so that the yarn moves more smoothly. When the movable ring comes into contact with the yarn, the connecting ring rotates and the movable ring rotates, reducing the friction between the yarn and the movable ring and reducing yarn wear.

The guide wheel 502 is added or removed according to the number of yarns to avoid the number of guide wheels 502 not matching the number of yarns and to prevent the guide wheels 502 from being excessive or insufficient. Specifically, guide rollers 2 are symmetrically fixed inside the mounting frame 1, and tension rollers 3 are movably connected inside the mounting frame 1. Slide grooves 303 are provided on the lower surfaces of both guide rollers 2 and tension rollers 3. Slide seats 501 are slidably connected inside the slide grooves 303. Screws 501a are threadedly connected to the lower surface of slide seats 501. Guide wheels 502 are provided below slide seats 501. Ear plates 502a are rotatably connected to both sides of guide wheels 502. Ear plates 502a are fixed to the lower surface of slide seats 501. Furthermore, a through groove 102 is provided on the side wall of the mounting frame 1, and guide grooves 102a are provided on both inner side walls of the through groove 102. Both ends of the tension roller 3 are fixedly connected to ear blocks 301, which are slidably connected inside the through groove 102. Slider blocks 301a are symmetrically fixedly connected to the two side walls of the ear blocks 301, which are slidably connected inside the guide grooves 102a. The motor 4 installed on the mounting frame 1 is located inside the through groove 102. A ball nut 401a is threaded on the peripheral side wall of the lead screw 401 connected to the output end of the motor 4. The ball nut 401a is interference-fitted to an ear block 301.
