Description

Technical Field

[0001] This utility model relates to the textile field, specifically a warp adjustment device for a high-speed rapier loom. Background Technology

[0002] In the textile industry, high-speed rapier looms are a common type of loom. They interweave warp and weft yarns according to the fabric design requirements to form fabric. The warp adjustment device is an important component of the rapier loom. In modern textile industry, high-speed rapier looms have become key equipment for fabric production due to their efficient and stable weaving performance.

[0003] Current warp adjustment devices for high-speed rapier looms struggle to achieve precise control over warp tension and position when faced with complex and varied weaving processes and diverse warp materials. This leads to uneven warp tension and positional deviations, resulting in fabric defects and a high defect rate, severely impacting product quality and corporate profitability. Furthermore, changing warp specifications or adjusting weaving processes requires significant time and tedious adjustments, causing frequent downtime that reduces equipment utilization and increases production costs. This fails to meet the market demands of modern textile production for small-batch, multi-variety, and rapid delivery. Therefore, we propose a warp adjustment device for high-speed rapier looms to address these issues. Utility Model Content

Tension adjustment nut 6 is connected to the upper surfaces of both support frames 1. A yarn guide nut 9 is commonly connected to the upper surfaces of both support frames 1. A quick-release nut 507 is rotated. The positive and negative screws 503 drive the two threaded blocks 504 to move in opposite directions, thereby opening the positioning clamping arms 505. Then, the mounting bracket 7 is placed between the two positioning clamping arms 505, and the quick-release nut 507 is rotated in the opposite direction to make the positioning clamping arms 505 lock the mounting bracket 7 through the pin 506. Then, the warp yarn is led out from the unwinding roll 2, passes through the warp yarn adjusting component 8, the warp yarn limiting sleeve 902, and the driven sleeve 606 on the tension adjusting rod 605 in sequence, and finally winds onto the take-up roll 3. Then, the unwinding motor 4 and the take-up motor 11 are started to make the warp yarn start to move. According to the warp yarn tension, the value of the pressure sensor 603 is observed, and the warp yarn tension is adjusted by extending and retracting the electric hydraulic telescopic rod 601 to make the warp yarn tension reach a suitable value. At the same time, the electric limiting slide rail 901 is activated, and the warp yarn limiting sleeve 902 slides on the electric limiting slide rail 901, which can prevent the warp yarn from tangling or being arranged in a disorderly manner, so that the warp yarn is arranged neatly and orderly, further improving the stability of weaving and product quality.

[0021] In this embodiment, the quick-connect component 5 includes a quick-connect frame 501 connected to the support frame 1. A limiting groove 502 is formed on the inner wall of the quick-connect frame 501. A positive and negative screw 503 is engaged with the inner wall of the limiting groove 502. Two threaded blocks 504 are threaded to the outer surface of the positive and negative screw 503. Positioning clamping arms 505 are connected to the left side of each of the two threaded blocks 504. Pins 506 are connected to the sides of the two positioning clamping arms 505 that are close to each other. A mounting bracket 7 is engaged with the sides of the two positioning clamping arms 505 that are close to each other via pins 506. Through the cooperation of the above structures, the quick installation of the mounting bracket 7 is achieved. Disassembly saves a lot of time. A set of warp adjustment components 8 is connected to the upper surface of the support frame 1. One end of the positive and negative screws 503 passes through the limiting slide groove 502 and extends to the outside of the quick-connect frame 501. One end of the positive and negative screws 503 is connected to a quick-release nut 507. The quick-release nut 507 makes it easy for the staff to rotate the positive and negative screws 503. Each tension adjustment component 6 includes an electric hydraulic telescopic rod 601 connected to the support frame 1. Each electric hydraulic telescopic rod 601 has an installation groove 602 inside. The installation groove 602 makes it easy for the staff to install the equipment components.

[0022] In this embodiment, a pressure sensor 603 is connected to the inner bottom wall of each mounting groove 602, and a driven shaft 604 is connected to the upper surface of each pressure sensor 603. A tension adjusting rod 605 is sleeved on the inner wall of each driven shaft 604, and a driven sleeve 606 is sleeved on the outer surface of the tension adjusting rod 605. The tension adjusting rod 605 can be used to precisely adjust the warp tension. The yarn guide 9 includes an electric limiting slide rail 901 connected to the support frame 1. A warp limiting sleeve 902 is slidably connected to the inner wall of the electric limiting slide rail 901. Through the cooperation of the above structures, the warp yarns can be effectively combed and limited, avoiding the warp yarns from tangling or being arranged in a disorderly manner.

[0023] Working principle: In use, first install the two support frames 1 in the appropriate positions, then rotate the quick-release nut 507 to make the positive and negative screws 503 drive the two threaded blocks 504 to move in opposite directions, thereby opening the positioning clamping arms 505. Next, place the mounting frame 7 between the two positioning clamping arms 505, and rotate the quick-release nut 507 in the opposite direction to make the positioning clamping arms 505 lock the mounting frame 7 through the pin 506. Then, draw the warp yarn from the pay-off spool 2 and pass it through the warp yarn adjusting component 8, the warp yarn limiting sleeve 902, and the tension... The driven sleeve 606 on the adjusting rod 605 is finally wound onto the take-up coil 3. Then, the unwinding motor 4 and the take-up motor 11 are started to make the warp yarn start to move. According to the tension of the warp yarn, the value of the pressure sensor 603 is observed. The tension of the warp yarn is adjusted by extending and retracting the electric hydraulic telescopic rod 601 to make the warp yarn tension reach a suitable value. At the same time, the electric limit slide rail 901 is activated, so that the warp yarn limit sleeve 902 slides on the electric limit slide rail 901 to comb and limit the warp yarn, ensuring that the warp yarn is neatly arranged.
