[0013] According to the above technical solution, a method for measuring twist for intelligent composite textiles, and a method for measuring twist for intelligent composite textiles using a twist measuring device, include the following steps: S1, pass one end of the yarn through the clamping roller, around the tensioning roller, through the rotating ring and the fixed cylinder, and then pass through the clamping roller on the other side of the top of the bottom frame, so that one end of the yarn can be passed through the lead block and wound around the outside of the take-up drum; S2, start the traction motor to drive the vertical rod and the take-up drum to rotate, and reel the yarn. At the same time, the micro motor drives the driving gear and the drum to rotate, pushing the lifting rod and the lead block to slide evenly inside the vertical frame, while fine-tuning the height of the yarn and reeling the yarn; S3. When the sample needs to be measured, stop the traction motor, rotate the inner cylinder and push the transmission gear and the adjusting rod to rotate through the gear ring, forcing the sleeve and the clamping frame to move, clamp one end of the yarn, and then rotate the screw rod to drive the two clamping plates to move relative to each other, clamping and fixing the other side of the yarn; S4, start the rotating motor, and then drive the rotating ring, the horizontal plate, the limit frame and the clamping frame to rotate through the cooperation of the driving gear and the driven gear, forcing the yarn to rotate and untwist, and at the same time pull the slide bar, the connecting plate and the clamping plate to move through the tension spring to tighten the yarn; S5, photograph and measure the untwisted yarn by using a measuring video recorder to check whether the yarn is completely untwisted and separated, and rotate the traction rod to raise the pad and the dividing needle to spread the two strands of yarn, and at the same time use the electric reciprocating linear slide to move the measuring video recorder and the dividing needle back and forth left and right; S6, the rotating ring rotates, and the top block rotates together with it. The touch switch is pushed intermittently to start the pressing counter, count the number of rotations of the rotating ring, and then calculate the twist of the yarn. At the same time, after the measurement is completed, the motor is rotated to drive the yarn to rotate again to reset the twist, and then the traction motor is started to rewind the yarn, and the measurement sample is reselected.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. A rotary untwisting and tensioning mechanism is provided. By rotating the inner cylinder and the gear ring, the transmission gear and the adjusting rod are rotated, and the shaft sleeve and the clamping frame are pushed to slide along the outer side of the limit frame, so as to change the distance between the two clamping frames. At the same time, the screw rod is rotated to drive the two clamping plates to move relative to each other, so as to facilitate the clamping and fixing of the two ends of the yarn, ensure the stability of the yarn, and facilitate the subsequent rotation of the motor, the driving gear, the driven gear, the rotating ring, the cross plate, the limit frame and the clamping frame to rotate the yarn and untwist and separate the yarn. At the same time, through the characteristics of the tension spring expansion and contraction, the sliding rod, the connecting plate and the clamping plate are pulled to move. When untwisting, the tension of the yarn is always maintained, so as to facilitate the observation of the effect of the yarn untwisting. In addition, through the cooperation of the traction rod and the pad, the dividing needle is raised and lowered and inserted between the two yarns to stretch the yarn, and then the electric reciprocating linear slide rail is used to move the movable plate, N-type frame, traction rod and dividing needle to separate the untwisted and separated yarns for inspection, and the yarn is filmed with a measuring video recorder. During the untwisting process of the yarn, the number of rotations of the yarn is recorded, and at the same time, it is observed whether the yarn is completely untwisted and separated to prevent the yarns from being entangled, thereby improving the measurement accuracy. In addition, the rotating ring rotates with the top block, and the touch switch is intermittently pushed to start the press counter to count the number of rotations of the rotating ring. When the yarn is completely untwisted and separated, the number of untwisted turns of the yarn is obtained by observing the data displayed on the press counter, which provides convenience for the subsequent measurement of the yarn twist.

[0015] 2. A traction and winding anti-deviation mechanism is set up. The reset spring pushes the support plate and the push rod to move, and the take-up drums with different inner diameters are supported and limited to ensure the stability of the take-up drum. The cooperation of the bidirectional screw, the movable block and the clamping roller facilitates the clamping and fixing of yarns of different sizes, thereby improving the adaptability. In addition, the support spring pushes the lifting plate and the tensioning roller to move, and the yarn is supported to ensure the tension of the yarn. At the same time, the rotating ring pushes the gasket ring to move, and the distance between the two gasket rings is changed, which facilitates the limitation of the yarn and prevents the yarn from deviating. The traction motor drives the vertical rod and the take-up drum to rotate, the yarn is wound, and the lead block is used to guide the yarn to prevent deviation. At the same time, the micro motor, driving gear, rotating drum, lifting rod, and travel switch cooperate to make the lead block slide up and down inside the vertical frame. This cycle is repeated while fine-tuning the yarn height and winding the yarn, so that the yarn can be evenly wound on the take-up drum to prevent stacking and ensure the winding effect.

[0016] In summary, by cooperating with the rotational untwisting and tensioning mechanism and the traction and winding anti-deviation mechanism, the yarn can be pulled and wound up conveniently. When winding up, it can stop and select a suitable measurement sample, and then drive the selected yarn sample to rotate, separate the yarn untwisting, and record the number of rotations at the same time, thereby improving the twist measurement effect. After the measurement is completed, the yarn twisting can be driven to recover, and then the yarn can be pulled and wound up again, thereby facilitating the subsequent selection of new samples, improving the convenience of sample selection, facilitating the comparison of measurement results, and improving the measurement effect.

A travel switch 423 is bolted at the top and bottom of the vertical frame 419 at an outer position of the lifting rod 421. A micro motor 424 is bolted at the bottom end of the base frame 1 at a position on one side of the rotating drum 420. A driving gear 425 is fixedly sleeved on the outer side of the output shaft of the micro motor 424 and the outer side of the rotating drum 420. In order to facilitate the lifting and lowering of the lead block 422, the two driving gears 425 are meshed with each other. The traction motor 418, the travel switch 423 and the micro motor 424 are all powered by an external power supply, and the signal output end of the travel switch 423 is connected to the input end of the micro motor 424.

[0022] like Figure 8 As shown, a method for measuring twist for intelligent composite textiles comprises the following steps: S1, pass one end of the yarn through the clamping roller 404, around the tensioning roller 410, through the rotating ring 302 and the fixed cylinder 318, and then pass through the clamping roller 404 on the other side of the top of the bottom frame 1, so that one end of the yarn can be passed through the lead block 422 and wound around the outside of the take-up drum; S2, start the traction motor 418 to drive the vertical rod 413 and the take-up drum to rotate, and reel the yarn. At the same time, the micro motor 424 drives the driving gear 425 and the rotating drum 420 to rotate, pushing the lifting rod 421 and the lead block 422 to slide evenly inside the vertical frame 419, while fine-tuning the height of the yarn and reeling the yarn; S3, when it is necessary to measure the sample, stop the traction motor 418, rotate the inner cylinder 312 and push the transmission gear 311 and the adjustment rod 310 to rotate through the gear ring 313, forcing the sleeve 309 and the clamping frame 308 to move, clamp one end of the yarn, and then rotate the screw rod 323 to drive the two clamping plates 324 to move relative to each other, clamping and fixing the other side of the yarn; S4, start the rotating motor 304, and then drive the rotating ring 302, the horizontal plate 306, the limiting frame 307 and the clamping frame 308 to rotate through the cooperation of the driving gear 305 and the driven gear 303, forcing the yarn to rotate and untwist, and at the same time pull the slide bar 320, the connecting plate 321 and the clamping plate 324 to move through the tensioning spring 322 to tighten the yarn; S5, the untwisted yarn is photographed and measured by the measuring video recorder 328 to check whether the yarn is completely untwisted and separated, and the traction rod 329 is rotated to lift the pad 330 and the dividing needle 331 to spread the two strands of yarn, and at the same time, the electric reciprocating linear slide 325 is used to move the measuring video recorder 328 and the dividing needle 331 back and forth; S6, the rotating ring 302 rotates, and the top block 314 rotates together with it, and the touch switch 316 is pushed intermittently to start the press counter 315, and the number of rotations of the rotating ring 302 is counted, and then the twist of the yarn is calculated. At the same time, after the measurement is completed, the rotating motor 304 drives the yarn to rotate again to reset the twist, and then the traction motor 418 is started to reel the yarn, and the measurement sample is reselected.

[0023] The working principle and use process of the present invention are as follows: first, the take-up drum is sleeved on the outer side of the vertical rod 413, and at the same time, the expansion and contraction characteristics of the return spring 417 are used to push the support plate 416 and the top rod 415 to move, forcing the outer side of the expansion plate 416 to fit closely with the inner wall of the take-up drum, thereby supporting and limiting the take-up drum to ensure the stability of the take-up drum, and then the yarn passes through the clamping roller 404 on one side of the top of the bottom frame 1, and the two-way screw 402 is rotated to push the two movable blocks 403 inside the same fixed frame 401 to move relative to each other, thereby changing the distance between the two clamping rollers 404, which is convenient for clamping and fixing yarns of different sizes, and at the same time, one end of the yarn bypasses the tensioning roller 410, and the ring 411 is rotated to push the pad ring 412 to move, thereby changing the distance between the two pad rings 412, thereby facilitating the yarn to limit the position and prevent the yarn from deflecting, and at the same time, the expansion and contraction characteristics of the support spring 409 are used to push the lifting plate 408 and the tensioning roller 410 to move, thereby supporting the yarn and ensuring the tension of the yarn; Next, one end of the yarn passes through the rotating ring 302 and the fixed cylinder 318, passes through the clamping roller 404 on the other side of the top of the bottom frame 1, and passes through the lead block 422, and then is wound around the outside of the take-up drum, so that the traction motor 418 can drive the vertical rod 413 and the take-up drum to rotate, and the yarn is wound. At the same time, the micro motor 424 is started synchronously, and the power is transmitted through the cooperation of the driving gear 425, driving the rotating drum 420 to rotate, pushing the lifting rod 421 and the lead block 422 to slide evenly inside the vertical frame 419, and the vertical frame 419 is at the highest point of the vertical frame 419 when the lead block 422 rises. When the lead block 422 is in the state of being ... Next, the traction motor 418 is stopped, the inner cylinder 312 is rotated, and the power is transmitted through the cooperation of the gear ring 313, pushing the transmission gear 311 and the adjusting rod 310 to rotate, and the clamping frame 308 is limited by the limit frame 307, so that the adjusting rod 310 pushes the shaft sleeve 309 and the clamping frame 308 to move, and the distance between the two clamping frames 308 is changed, and one side of the yarn is clamped and fixed, and then the screw rod 323 is rotated to drive the two clamping plates 324 to move relative to each other, and the other side of the yarn is clamped and fixed, and then the rotating motor 304 is started, and at the same time, the power is transmitted through the cooperation of the driving gear 305 and the driven gear 303, driving the rotating ring 302 to rotate, and the yarn is rotated through the cooperation of the cross plate 306, the limit frame 307 and the clamping frame 308, and the yarn is untwisted; In addition, as the yarn continues to rotate, the wound yarn is untwisted and separated, so that the two wound yarns are parallel, and the traction rod 329 is rotated to bring the pad 330 and the dividing needle 331 up, so that the dividing needle 331 can spread the two yarns apart, and the electric reciprocating linear slide 325 is used to bring the moving plate 326, the N-shaped frame 327, the traction rod 329 and the dividing needle 331 to move back and forth left and right to inspect the untwisted and separated yarns, and at the same time, the measurement video recorder 328 is used to take pictures and compare to observe whether the yarn is completely untwisted and separated, thereby improving the measurement accuracy; Finally, when the rotating ring 302 rotates, it rotates with the top block 314, and then intermittently pushes the touch switch 316 to start the press counter 315 to count the number of rotations of the rotating ring 302. When the yarn is completely untwisted and separated, the rotating motor 304 is stopped, and the number of untwisted turns of the yarn is obtained by observing the data displayed on the press counter 315, which provides convenience for the subsequent measurement of the yarn twist. In addition, during the untwisting process, the sliding rod 320, the connecting plate 321 and the clamping plate 324 are pulled to move through the telescopic characteristics of the tensioning spring 322, so as to always keep the tension of the yarn, so as to facilitate the observation of the effect of the yarn untwisting.
