Description

Technical Field

[0001] The invention relates to the technical field of fiber detection, in particular to a lyocell fiber stretching detection device. Background Art

[0002] Lyocell fiber is made of pulp formed by crushing renewable bamboo, wood, etc. It is not only energy-saving, environmentally friendly, but also sustainable. Clothes made of this fiber not only have a natural luster, smooth feel, high strength, and basically no shrinkage, but also have good moisture permeability and air permeability. It has a good effect when blended with wool. The Chinese patent application number 202410526788.3 discloses "a tensile testing device for glass fiber products, including a mounting plate, the upper surface of which is equipped with a sliding first displacement seat and a second displacement seat, and the outer surfaces of the first displacement seat, the second displacement seat and the locking plate are arranged The device is equipped with a self-locking mechanism, which can automatically lock the workpiece to be tested by placing it. A stretching motor is fixedly installed on the upper surface of the mounting plate, and an automatic cleaning mechanism is arranged on the mounting plate to ensure the clamping stability of the workpiece to be tested by cleaning the surface of the workpiece to be tested. The tensile testing device for glass fiber products adopts a method of installing a rotating ring on one end of the mounting plate, and uses a cleaning brush to clean the surface of the glass fiber tube to be tested during the rotation of the rotating ring, so that the residual glass fiber on the surface of the glass fiber tube can be cleaned to avoid affecting the normal detection.

[0003] This technical solution only solves the problem of slippage between the fiber and the clamping assembly during the test. However, in the tensile test of Lyocell fiber, a large number of samples are often required to be tested. During the test, the fiber is fixed by end winding. When the number of samples is large, it will cause a serious waste of time and energy of the test personnel, affecting the test efficiency. It may also cause the fiber to be affected by tension during winding, resulting in inaccurate test data. In addition, at the end of the test or when the sample is replaced, it is often necessary to remove the previous test sample from the test device, and the fiber will be wound around the reel assembly during the test, which makes cleaning inconvenient and affects the test efficiency.

[0041] Working principle: When the present invention is in use, the two ends of the lyocell fiber are placed on the two fiber reels 304 respectively, and the lyocell fiber is located between the fixed clamping groove 401 and the fixed clamping plate 405. At this time, the hand wheel 411 is pulled to drive the rotating shaft 303 to move in the direction close to the support plate 301 through the hand wheel 411, so that the limiting rod 408 moves with the rotating shaft 303, and the rotating shaft 303 does not affect the rotation of the rotating disk 402 when moving through the slot 409. After the limiting rod 408 is pulled out of the first limiting groove 406 by pulling the rotating shaft 303, the fiber reel 304 is held, the hand wheel 411 is rotated, and the limiting rod 408 is driven by the rotating shaft 303 to rotate forty-five degrees, and then the hand wheel 411 is released. Under the elastic force of the spring 412, the limiting rod 408 is inserted into the second limiting groove 407 and remains fixed in the second limiting groove 407. When the rotating shaft 303 rotates, the rotating rod 410 is driven to rotate simultaneously through the slot 409, so that the rotating disk 402 rotates along with the rotating rod 410. When the rotating disk 402 rotates, the retractable plate 404 is driven to move into the fiber reel 304 through the rotating groove 403, and the fixed clamping plate 405 is driven to move into the fixed clamping groove 401 through the retractable plate 404, so that the Lyocell fiber end placed between the fixed clamping groove 401 and the fixed clamping plate 405 is clamped, thereby reducing the steps of fixing the fiber end by winding multiple times, and improving the efficiency of Lyocell fiber tensile testing;

[0042] After the end of the lyocell fiber is fixed, the first motor 313 is started, and the two worms 311 are driven to rotate simultaneously through the transmission rod 312. Since the threads on the two worms 311 are in opposite directions, the two worm wheels 310 rotate in opposite directions under the drive of the worms 311. The worm wheels 310 drive the gear shaft 308 to rotate, so that the second gear 309 rotates following the gear shaft 308. The second gear 309 drives the first gear 307 to rotate, so that the connecting shaft 305 rotates following the first gear 307. When the connecting shaft 305 rotates, the connecting shaft 305 rotates. When the first motor 313 is controlled to rotate, the fiber reel 304 is driven to rotate, and the two fiber reels 304 rotate in opposite directions. After the end of the Lyocell fiber is fixed on the fiber reel 304, when the two fiber reels 304 rotate, the Lyocell fiber is stretched. The rotation of the fiber reel 304 is controlled by controlling the first motor 313 to control the application of different tensions to the Lyocell fiber. The data of the stretching test is displayed on the test data display screen 2, so that the stretching test of the Lyocell fiber can be carried out simply and effectively, thereby improving the test efficiency.

[0043] After the test is completed, the Lyocell fiber needs to be removed from the device for the next test. The hand wheel 411 is pulled and rotated in the opposite direction to drive the telescopic plate 404 to extend out of the fiber reel 304. At this time, the fixed clamping plate 405 and the fixed clamping groove 401 are no longer clamped. Then the second motor 504 is started to drive the threaded rod 503 to rotate. Under the limiting action of the limiting frame 501 and the sliding rod 502, when the threaded rod 503 rotates, it drives the translation plate 505 to move in the direction close to the support plate 301. When the translation plate 505 moves, the rotating plate 605 is driven to move synchronously with the translation plate 505 through the connecting ring 506, and the translation ring 601 is driven to move synchronously with the rotating plate 605 through the connecting rod 604. The rotating plate 605 can rotate synchronously with the synchronous rod 306 through the connecting ring 506, so that The cutting knife 602 and the pushing rod 603 in the translation ring 601 can rotate simultaneously with the fiber reel 304, and when the translation ring 601 moves toward the support plate 301, the cutting knife 602 is driven to move along the knife groove 606, and the pushing rod 603 is driven to move along the rod groove 607, so that the Lyocell fiber rolled up on the fiber reel 304 is pushed out of the fiber reel 304 by the pushing rod 603, and the cutting knife 602 is used to prevent the fiber from being entangled on the fiber reel 304 and being difficult to push out. When the detection is completed or the detection fiber is replaced, the pushing rod 603 automatically pushes the fiber away from the fiber reel 304, and the cutting knife 602 is used to prevent the fiber that is difficult to push out from being entangled on the fiber reel 304, which improves the material replacement efficiency while ensuring the integrity of the middle section of the Lyocell fiber used for stretching, which not only improves the detection efficiency but also reduces the time and energy of the staff.
