Description

Technical Field

[0001] The present invention relates to the technical field of textile detection, and particularly relates to a textile fiber strength detection device and a detection method thereof. Background Art

[0002] Textiles refer to fiber products processed through textile processes, including clothing, home textiles, industrial textiles, etc. After the textiles are processed, sampling and testing are required to determine the strength of the textiles.

[0003] A common detection method is to clamp both ends of a textile sample with two clamping seats respectively, then connect one clamping seat to a tensile force sensor and the other clamping seat to a cylinder. By operating the cylinder, the textile sample can be stretched, and the tensile force received by the textile can be recorded through the tensile force sensor.

[0004] Traditional clamping seats for textile samples are serrated clamping seats. When clamping a textile sample, this kind of clamping seat will produce a biting phenomenon, making the clamping surface larger and the clamping of the textile sample more stable. However, with the increase in the number of detections, when the serrations bite into the textile sample, some fibers will be cut off or worn, and these fiber debris will remain in the serration gaps. However, the serrated clamping seats make it inconvenient to clean the fiber debris, and the staff cannot ensure that each detection is followed by a cleaning. As a result, during multiple detections, repeated clamping will compact at the root of the serrations, forming a hardened layer similar to a "fiber felt". As the debris accumulates, the actual biting depth of the serrations decreases, resulting in a decrease in the clamping force, and making the measurement inaccurate due to unstable clamping of the textile sample during the detection process. Therefore, we propose a textile fiber strength detection device and a detection method thereof. Summary of the Invention

[0055] Technical effects and advantages of the present invention:

[0056] (1) By setting up the cleaning mechanism and the one-way mechanism in the present invention, when the sliding seat rises, the first turntable rotates, and then under the connection of the connecting rod, the piston block reciprocates in the moving cavity, so that external air enters the inside of the moving cavity through the first one-way valve, and then enters the connecting cavity through the second one-way valve, and finally blows to the position of the fixture assembly through a plurality of air outlet holes, so that the debris in the fixture assembly is blown out. Therefore, the fixture assembly can be automatically cleaned when the sliding seat resets after each detection, without the need for direct cleaning by the staff, avoiding the phenomenon of debris accumulation in the fixture assembly and ensuring the stable clamping of the textile debris by the fixture assembly;

[0057] (2) By setting up the deceleration mechanism in the present invention, when the textile sample breaks, the sliding seat block above moves upward, and the third turntable will rotate rapidly under the action of the connecting mechanism, so that the clamping shaft is subjected to a large centrifugal force, so that the two clamping shafts move away from each other against the elastic action of the tension spring until the clamping shaft is inserted into the clamping hole. At this time, the rotation of the third turntable drives the extrusion disc to rotate, thereby increasing the resistance to the rotation of the third turntable and slowing down the upward movement speed of the sliding seat;

[0058] (3) By setting up the buffer mechanism and the release mechanism in the present invention, when the deceleration mechanism works, the extrusion disc rotates and presses against the hemispherical surface, causing the unlocking shaft to move. The unlocking shaft moves and presses the rolling ball, so that the positioning shaft moves until the positioning shaft is separated from the positioning hole. At this time, under the elastic action of the first compression spring, the movable rod directly drives the clamping block to move upward, so that the clamping block protrudes from the top of the slider. Therefore, when the sliding seat moves upward, the protruding clamping block will first contact the second extrusion block, and then buffer the impact force through the first compression spring, which can reduce the impact force when the sliding seat moves upward and rebounds, thus playing a protective effect on the tensile force sensor.

Detailed implementation manners

[0071] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0072] The present invention provides as Figures 1 - 11A textile fiber strength testing device shown includes a frame 101, a testing mechanism, a cleaning mechanism, a protective mechanism, a one-way mechanism, a deceleration mechanism and a release mechanism. The testing mechanism is arranged inside the frame 101, the cleaning mechanism is arranged inside the testing mechanism, the cleaning mechanism is used to remove the debris remaining in the testing mechanism, the protective mechanism is arranged inside the frame 101, the protective mechanism is used to buffer the impact force generated when the textile breaks, the one-way mechanism is connected to the cleaning mechanism, the deceleration mechanism is arranged inside the frame 101, and the release mechanism is arranged between the deceleration mechanism and the protective mechanism. The textile sample clamped in the frame 101 is tested by the testing mechanism. After the test is completed, with the cooperation of the one-way mechanism, the cleaning mechanism is operated to automatically clean the textile debris remaining in the testing mechanism. At the same time, with the cooperation of the release mechanism, the deceleration mechanism and the protective mechanism are operated, thereby unloading and buffering the impact force generated after the textile sample breaks, thereby improving the protection effect of the equipment.

[0073] The detection mechanism includes a slide 104, a fixture assembly 106 and a slider 301. The two slides 104 are respectively slidably arranged inside the frame 101. The inner wall of the frame 101 is installed with a cylinder 103. The output end of the cylinder 103 is transmission-connected to the bottom end of one of the slides 104. A tension sensor 105 is installed at the top of the inner wall of the frame 101. The tension sensor 105 is connected to the top of another slide 104. The cleaning mechanism is arranged inside the slide 104. The fixture assembly 106 is respectively arranged on the outer walls of the two slides 104. The slider 301 is fixedly connected to both sides of the slide 104. Both sides of the inner wall of the frame 101 are provided with The outer wall of the slide 302 and the slider 301 are slidably connected to the inner wall of the slide 302. The clamp assembly 106 is a traditional serrated clamp. The top of the textile sample is first clamped by the upper clamp assembly 106, and then the bottom of the textile sample is clamped by the lower clamp assembly 106. Then the cylinder 103 works to drive the lower slide 104 to descend, so that the clamped textile sample can be stretched. At this time, the tension sensor 105 will record the tension on the textile sample until the textile sample is broken. At this time, the tension sensor 105 records the maximum tension on the textile sample, thereby completing the strength test of the textile fiber.

[0074] Among them, the cleaning mechanism includes a movable cavity 201, a piston block 202, a first one-way valve 203, a connecting cavity 204, a second one-way valve 205, and an air outlet 206. The movable cavity 201 is formed between the sliding seat 104 and the slider 301. The piston block 202 is symmetrically and slidably connected to the inner wall of the movable cavity 201. A reciprocating mechanism is provided on one side of the piston block 202. The first one-way valve 203 is inserted and installed at the top of the inner wall of the movable cavity 201. The connecting cavity 204 is formed inside the sliding seat 104. The second one-way valve 205 is inserted and installed between the movable cavity 201 and the connecting cavity 204. The air outlet 206 is distributed on the outer wall of the sliding seat 104. The inside of the air outlet 206 is communicated with the inside of the connecting cavity 204. The air outlet 206 corresponds to the position of the fixture assembly 106. The reciprocating mechanism includes a first turntable 304, a connecting rod 305, and a fixing plate 306. A slot 303 is formed on the front surface of the slider 301. Therefore, the first turntable 304 is rotatably arranged inside the slot 303. The one-way mechanism is connected to the first turntable 304. One end of the connecting rod 305 is rotatably connected to the side of the front surface of the first turntable 304. The fixing plates 306 are symmetrically and fixedly connected to one side of the piston block 202. The other end of the connecting rod 305 is rotatably connected between the two fixing plates 306. With the cooperation of the one-way mechanism, when the sliding seat 104 rises, the first turntable 304 rotates. Then, under the connection of the connecting rod 305, the piston block 202 reciprocates in the movable cavity 201, so that external air enters the inside of the movable cavity 201 through the first one-way valve 203, then enters the connecting cavity 204 through the second one-way valve 205, and finally is blown to the position of the fixture assembly 106 through a plurality of air outlets 206, so that the debris in the fixture assembly 106 is blown out. Thus, the fixture assembly 106 can be automatically cleaned when the sliding seat 104 resets after each detection, without the need for direct cleaning by the staff, avoiding the phenomenon of debris accumulation in the fixture assembly 106 and ensuring the stable clamping of textile debris by the fixture assembly 106.

[0075] Among them, the one-way mechanism includes a first rotating shaft 307, an inner ratchet groove 309, a second turntable 308 and ratchet teeth 310. The first rotating shaft 307 is rotatably connected to the inner wall of the slot 303. A connecting mechanism is provided on the outer wall of the first rotating shaft 307. The speed reduction mechanism is connected to the first rotating shaft 307. The inner ratchet groove 309 is opened on the front surface of the first turntable 304. One end of the first rotating shaft 307 penetrates through the back surface of the first turntable 304 and extends into the inner ratchet groove 309. The first turntable 304 is rotatably sleeved on the outer wall of the first rotating shaft 307. The second turntable 308 is arranged inside the inner ratchet groove 309. The back surface of the second turntable 308 is fixedly connected to one end of the first rotating shaft 307. A connecting shaft 311 is fixedly connected to the front surface of the second turntable 308. The ratchet teeth 310 are rotatably sleeved on the outer wall of the connecting shaft 311. An annular groove 312 is opened on the inner wall of the ratchet teeth 310. A torsion spring 313 is arranged inside the annular groove 312. The torsion spring 313 is sleeved on the outer wall of the connecting shaft 311. One end of the torsion spring 313 is connected to the inner wall of the annular groove 312, and the other end of the torsion spring 313 is connected to the outer wall of the connecting shaft 311. Through the cooperation of the ratchet teeth 310 and the inner ratchet groove 309, the second turntable 308 on the left can drive the corresponding first turntable 304 to rotate counterclockwise only when rotating counterclockwise, and the second turntable 308 on the right can drive the corresponding first turntable 304 to rotate clockwise only when rotating clockwise. Thus, with the cooperation of the connecting mechanism, the reciprocating mechanism can only work when the slide seat 104 rises. Therefore, when the two slide seats 104 descend to detect the textile sample, the cleaning mechanism will not work, avoiding affecting the cleaning mechanism.

[0076] Among them, the connecting mechanism includes a gear 401 and a rack 402. The gear 401 is fixedly sleeved on the outer wall of the first rotating shaft 307. The rack 402 is fixedly connected to the inner wall of the chute 302. The outer wall of the gear 401 is meshed with one side of the rack 402. When the slide seat 104 descends, through the meshing of the gear 401 and the rack 402, it can be ensured that only when the slide seat 104 rises, the gear 401 on the right drives the second turntable 308 to rotate clockwise through the first rotating shaft 307, and the gear 401 on the left drives the corresponding second turntable 308 to rotate counterclockwise. Thus, when the slide seat 104 rises after the detection is completed, the one-way mechanism will drive the cleaning mechanism to work automatically without the participation of other drives, which not only ensures the convenience of the cleaning mechanism work but also reduces the equipment cost.

[0077] Among them, the speed reduction mechanism includes a first rotating groove 702, a third turntable 706 and a clamping shaft 708. The first rotating groove 702 is opened inside the slider 301. The inner wall of the first rotating groove 702 is rotatably connected to a second rotating shaft 704. One end of the second rotating shaft 704 is fixedly connected to an extrusion disc 703. A second rotating groove 705 is opened on the front surface of the extrusion disc 703. The third turntable 706 is rotatably arranged inside the second rotating groove 705. The front surface of the third turntable 706 is fixedly connected to the other end of the first rotating shaft 307. A communication hole 707 is opened on the outer wall of the third turntable 706. The clamping shafts 708 are symmetrically and movably arranged on the inner wall of the communication hole 707. A tension spring 709 is arranged between the two communication holes 707. Symmetrical clamping holes 710 are opened on the inner wall of the second rotating groove 705. Symmetrical limiting grooves 711 are opened on the inner wall of the communication hole 707. Limiting blocks 712 are fixedly connected to both sides of the clamping shaft 708. The outer wall of the limiting block 712 is slidably connected to the inner wall of the limiting groove 711. The speed reduction mechanism and the buffer mechanism are only arranged inside the sliders 301 on both sides of the upper slide base 104. Because when the textile breaks, the lower slide base 104 is connected to the cylinder 103, so that this slide base 104 will not move upward automatically. However, the upper slide base 104 will move upward quickly in the reverse direction immediately after the textile breaks. The speed reduction mechanism slows down the upward movement speed of the slide base 104, and at the same time, the buffer mechanism buffers the impact force when the slide base 104 moves. When the upper slide base 104 moves upward quickly, the third turntable 706 will rotate quickly under the action of the connecting mechanism, so that the clamping shaft 708 is subjected to a large centrifugal force, so that the two clamping shafts 708 move away from each other against the elastic action of the tension spring 709 until the clamping shaft 708 is inserted into the clamping hole 710. At this time, the rotation of the third turntable 706 drives the extrusion disc 703 to rotate, thereby increasing the resistance to the rotation of the third turntable 706, thereby slowing down the upward movement speed of the slide base 104.

[0078] Among them, the buffer mechanism includes a clamping block 502, a first compression spring 505, a fixed tube 506 and a first extrusion block 510. A clamping groove 501 is formed at the top end of the slider 301. The outer wall of the clamping block 502 is movably inserted into the inner wall of the clamping groove 501. A movable rod 504 is fixedly connected to the bottom end of the clamping block 502. A movable hole 503 is formed at the bottom end of the inner wall of the clamping groove 501. The outer wall of the movable rod 504 is movably inserted into the inner wall of the movable hole 503. The release mechanism is arranged between the movable rod 504 and the extrusion disc 703. The first compression spring 505 is arranged at the bottom end of the movable rod 504. A fixed tube 506 is fixedly connected to the inner wall of the sliding groove 302. A first insertion hole 507 is formed at the bottom end of the fixed tube 506. A second insertion hole 508 is formed at the top end of the frame body 101. An extrusion rod 509 is movably inserted into the inner walls of the second insertion hole 508 and the first insertion hole 507. The first extrusion block 510 is fixedly connected to the top end of the extrusion rod 509. A second extrusion block 511 is fixedly connected to the bottom end of the extrusion rod 509. The release mechanism includes a positioning shaft 602, an unlocking shaft 605 and a rolling ball 607. A connection hole 601 is formed on one side of the movable rod 504. The outer wall of the positioning shaft 602 is movably inserted into the inner wall of the connection hole 601. A second compression spring 603 is arranged between the positioning shaft 602 and the inner wall of the connection hole 601. A positioning hole 604 is formed between the movable hole 503 and the first rotating groove 702. The outer wall of the positioning shaft 602 is movably inserted into the inner wall of the positioning hole 604. The unlocking shaft 605 is movably inserted into the inner wall of the positioning hole 604. A hemispherical surface 701 is formed at one end of the unlocking shaft 605 away from the positioning shaft 602. An annular cavity 608 is formed on the inner wall of the positioning hole 604. A fixed ring 609 is slidably connected to the inner wall of the annular cavity 608. The fixed ring 609 is fixedly sleeved on the outer wall of the unlocking shaft 605. A third compression spring 610 is arranged between one side of the fixed ring 609 and the inner wall of the annular cavity 608. The third compression spring 610 is sleeved on the outer wall of the unlocking shaft 605. A ball hole 606 is formed at one end of the positioning shaft 602 close to the unlocking shaft 605. The rolling ball 607 is movably clamped in the inner wall of the ball hole 606. When the extrusion disc 703 is not driven by the third turntable 706, it is as Figure 10As shown, two arc segments of different sizes face downwards and upwards respectively, so that the upper slide block 104 moves upwards at high speed after bouncing. As long as the third turntable 706 drives the extrusion disc 703 to rotate by 45°, the extrusion disc 703 can extrude the hemispherical surface 701, causing the unlocking shaft 605 to move. The unlocking shaft 605 moves to extrude the rolling ball 607, thereby causing the positioning shaft 602 to move until the positioning shaft 602 separates from the positioning hole 604. At this time, under the elastic action of the first compression spring 505, the movable rod 504 directly drives the latch 502 to move upwards, making the latch 502 protrude from the top of the slider 301. Therefore, when the slide block 104 moves upwards, the protruding latch 502 will first contact the second extrusion block 511, and then buffer the impact force through the first compression spring 505, reducing the impact force when the slide block 104 moves upwards and rebounds, thus protecting the tension sensor 105. Until the upper slide block 104 completely returns to its original position and stops, the extrusion disc 703 automatically returns to Figure 10 its original state. Then, the operator holds the upper slide block 104 with one hand and presses the first extrusion block 510 with the other hand, causing the extrusion rod 509 to move downwards. The downward movement of the extrusion rod 509 drives the second extrusion block 511 to move downwards. The downward movement of the second extrusion block 511 extrudes the latch 502, causing the movable rod 504 to compress the first compression spring 505 and move downwards until the latch 502 is completely inserted into the card slot 501. At this time, the positioning shaft 602 aligns with the positioning hole 604, and under the elastic action of the second compression spring 603, the positioning shaft 602 can be inserted into the positioning hole 604, thus resetting and hiding the protection mechanism, ensuring that the buffer mechanism will not affect the measurement of the tension sensor 105 at the start of the detection and guaranteeing the accuracy of the tension sensor 105 during operation.

[0079] When the device works, first clamp the top of the textile sample through the fixture assembly 106 above, then clamp the bottom of the textile sample through the fixture assembly 106 below, and then the cylinder 103 works to drive the lower slide 104 to descend, so as to stretch the clamped textile sample. At this time, the tension sensor 105 will record the tension received by the textile sample until the textile sample is broken. At this time, the tension sensor 105 records the maximum tension received by the textile sample, and the strength detection of the textile fiber is completed. At this time, the upper slide 104 rebounds and moves upward rapidly, the gear 401 engaged with the rack 402 rotates, the rotation of the gear 401 drives the first rotating shaft 307 to rotate, the rotation of the first rotating shaft 307 drives the second turntable 308 to rotate, and the inner wall of the inner ratchet groove 309 is clamped by the ratchet teeth 310, so that the first turntable 304 rotates. Then, under the connection of the connecting rod 305, the piston block 202 reciprocates in the movable cavity 201, so that the external air enters the inside of the movable cavity 201 through the first one-way valve 203, and then enters the connecting cavity 204 through the second one-way valve 205, and finally blows to the position of the fixture assembly 106 through a plurality of air outlets 206, so that the debris in the fixture assembly 106 is blown out; while the upper slide 104 rebounds at high speed, the first rotating shaft 307 drives the third turntable 706 to rotate rapidly, so that the clamping shaft 708 is subjected to a large centrifugal force, so that the two clamping shafts 708 move away from each other against the elastic force of the tension spring 709 until the clamping shaft 708 is inserted into the clamping hole 710. At this time, the rotation of the third turntable 706 drives the extrusion disc 703 to rotate, thereby increasing the resistance received by the rotation of the third turntable 706, thereby slowing down the upward movement speed of the slide 104. When the extrusion disc 703 rotates, it squeezes the hemispherical surface 701, so that the unlocking shaft 605 moves, and the unlocking shaft 605 moves to squeeze the rolling ball 607, so that the positioning shaft 602 moves until the positioning shaft 602 is separated from the positioning hole 604. At this time, under the elastic force of the first compression spring 505, the movable rod 504 directly drives the clamping block 502 to move upward, so that the clamping block 502 protrudes from the top of the slider 301. Therefore, when the slide 104 moves upward, the protruding clamping block 502 will first contact the second extrusion block 511, and then buffer the impact force through the first compression spring 505.

[0080] The present invention also provides a method for detecting the strength of textile fibers, including the following steps:

[0081] Step 1: Cut the textile sample to be tested into a standard size, clamp and fix the top of the textile sample through the fixture assembly 106 on the upper second slide 104, and clamp and fix the bottom of the textile sample through the fixture assembly 106 on the lower first slide 104;

[0082] Step 2: Start the cylinder 103 to drive the first sliding seat 104 below to move downward at a constant speed, apply a tensile force to the textile sample, monitor the change in the tensile force received by the textile sample in real time through the tensile force sensor 105, and record the force-displacement data during the stretching process;

[0083] Step 3: Transmit the tensile force data measured by the tensile force sensor 105 to the cloud database in real time for storage and analysis, draw the tensile force-time and tensile force-displacement curves through software, and monitor the change in the mechanical properties of the textile sample;

[0084] Step 4: Continuously stretch until the textile sample breaks, and record the maximum tensile force value of the tensile force sensor 105 at the moment of fracture as the fiber strength detection result.
