Description

Technical Field

[0001] The invention relates to the technical field of textile yarn detection equipment, in particular to a fire-fighting textile yarn tensile performance detection equipment. Background Art

[0002] Firefighting textile materials, as key components of firefighting protective equipment (such as firefighting suits, firefighting gloves, etc.) and firefighting facilities (such as fire curtains, etc.), play a vital role in ensuring personnel safety and suppressing the spread of fire; firefighting textile yarns, as the basic building blocks of these materials, directly determine the quality and use effect of the final firefighting textile products. Among the many performance indicators, tensile performance is particularly critical, so testing equipment is needed to test the tensile performance of textile yarns.

[0003] However, the current textile yarn tensile performance testing equipment cannot quickly test multiple gauze samples during tensile testing, and the efficiency of the tensile performance test is low. At the same time, when fixing the textile cloth strips, the operator needs to manually load the material, adjust the tightness of the clamp by turning the bolt of the clamp, and then clamp the gauze strip. When replacing the gauze strip, the bolt needs to be repeatedly loosened and tightened, and the fixing efficiency is low. At the same time, due to the manual control of clamping the gauze strip, the clamping force is not easy to control. When the clamping force is small, it is easy to cause the gauze strip to slip during the tensile test. Excessive clamping force can easily cause the gauze strip to break at the clamping position, affecting the accuracy of the test results. At the same time, since the maximum distance between the two clamps is fixed, it is not convenient to test the maximum stretching amount of some longer cloth strips, and it is not convenient to quickly adjust the distance between the two clamps according to the length of the gauze strip tested. The tensile performance test effects of gauze strips of different lengths are different, resulting in poor test results. Summary of the invention

The first hydraulic rod 504 pushes the push block 505, the plug block 506, the pull rod 508, the fixed plate 507 and the placement box 601 to move, and then the next placement slot 602 and the gauze strip to be tested in the placement slot 602 are pulled to one side of the slide bar 210, and then the clamping block 304 on the slide bar 210 is placed on both sides of the gauze strip to be tested by starting the second hydraulic rod 701, and then the clamping detection operation is performed, and this reciprocating operation realizes the rapid and automatic feeding of the gauze strips and improves the detection efficiency; Specifically, Figure 1 , Fig.10 , Fig.11 , Fig.12 and Fig.14As shown, the interior of the slide bar 210 is symmetrically slidably connected to two slides 704, and the slide bars 704 are rotatably connected to a clamping roller 705, and a plurality of connecting rods 708 are fixedly connected to the slide bars 704, and the connecting rods 708 are slidably connected to the slide bar 210, and a third spring 709 is fixedly connected between the connecting rods 708 and the slide bar 210, and a guide bar 710 is fixedly connected to the slide bar 210, and the guide bar 710 is slidably connected to the mounting bar 209; the mounting bar 209 is provided with two symmetrical first slide grooves 703, and the end section of the first slide groove 703 is a trapezoidal structure, and the slide bar 210 is symmetrically provided with two second slide grooves 703. The guide block 706 is fixedly connected to the slide 704, and the guide block 706 is slidably connected to the first slide groove 703, and the guide block 706 is slidably connected to the second slide groove 707; when the second hydraulic rod 701 drives the slide bar 210 to slide, when the guide block 706 on the slide bar 210 slides out of the first slide groove 703 on the mounting strip 209, the third spring 709 is reset, thereby driving the connecting rods 708 on both sides of the gauze strip to slide toward each other, the connecting rods 708 drive the slide 704 to slide toward each other, the slide 704 drives the clamping roller 705 to move, and at the same time the guide block 706 slides in the second slide groove 707, and the two clamping rollers 705 clamp the gauze strip, so that When the clamping block 304 at the bottom clamps the gauze strip and pulls it downward, the gauze strip can maintain a certain tension to prevent the gauze strip from becoming loose and falling when being loaded.

Then the gauze strip is clamped by the clamping structure at the top, and then the tensile performance test is performed to prevent the gauze strip from wrinkling at the end when clamping. When the test is completed, the gauze strip sample that has been tested is taken out, and then the second hydraulic rod 701 contracts to drive the push plate 702 and the slide bar 210 to slide. Since the entrance of the first slide groove 703 is a trapezoidal structure, the guide block 706 conflicts with the inclined position of the first slide groove 703 and continues to contract. When the second hydraulic rod 701 is activated, the slide bar 210 continues to slide, and the two guide blocks 706 will slide horizontally and opposite to each other in the second slide groove 707, thereby driving the slide 704 to slide opposite to each other, and the slide 704 drives the connecting rod 708 to slide opposite to each other, and the third spring 709 is compressed, and the distance between the two clamping rollers 705 increases. In this way, when the slide bar 210 slides out of part of the position of the mounting strip 209, due to the large distance between the clamping rollers 705, it can move smoothly to both sides of the gauze strip. The resistance of the first slide groove 703 to the guide block 706 will not be lost until the guide block 706 slides out completely, and the third spring 709 can be reset to drive the clamping roller 705 to clamp the gauze strip.

[0026] When the present invention is in use, first, when it is necessary to test the tensile performance of the gauze strip, the second hydraulic rod 701 can be started, the second hydraulic rod 701 drives the push plate 702 to move, the push plate 702 drives the slide bar 210 to slide, the notch on the slide bar 210 slides to the outside of the gauze strip, and then the first motor 202 is started, the first motor 202 drives the first screw 203 to rotate, the first screw 203 rotates to drive the lifting plate 204 to slide on the stand 201, the lifting plate 204 rises to the bottom end of the gauze strip, and then the second motor 301 on the fixed bar 206 is started, the second motor 301 drives the second screw 302 to rotate, and the second screw 203 rotates to drive the lifting plate 204 to slide on the stand 201, and the lifting plate 204 rises to the bottom end of the gauze strip. The threads at both ends of the rod 302 are in opposite directions, so the threads drive the two slide plates 303 to slide towards each other. The setting of the guide shaft 308 improves the sliding stability of the slide plate 303. The slide plate 303 slides towards each other, thereby driving the two clamping blocks 304 to slide towards each other. The two clamping blocks 304 clamp the gauze strip. The protrusion 305 on one clamping block 304 engages with the groove 306 on the other clamping block 304. At the same time, a wear-resistant layer 307 is provided on the clamping block 304, which improves the clamping effect and effectively prevents the gauze strip from slipping during the tension test. When it is necessary to test gauze strips of different thicknesses, the parameters of the second motor 301 can be adjusted according to the thickness of the gauze strip. The clamping force is controlled to avoid the gauze strip from being broken due to local force, thereby improving the accuracy of detection. When the clamping block 304 below clamps the bottom end of the gauze strip, the first motor 202 drives the first screw 203 to rotate, thereby driving the lifting plate 204 to move toward each other, driving the clamping block 304 to move downward, and then stretching the gauze strip downward until the gauze strip is completely pulled out of the placement structure 6. At this time, the second motor 301 on the slide bar 210 is started to drive the two clamping blocks 304 to clamp the top of the gauze strip. After clamping, the gauze strip is subjected to a tension test. During the tension test, the first motor 202 is continued to be started. The first motor 202 drives the lifting plate 204 to move toward each other, and drives the clamping block 304 to move downward, thereby stretching the gauze strip downward. The descending plate 204 and the clamping block 304 below move downward to stretch the gauze strip, and the gauze strip pulls the clamping block 304 above and the slide bar 210, and the slide bar 210 pulls the mounting bar 209, and the mounting bar 209 pulls the tension sensor 208, and the tension sensor 208 feeds back the tension to the computer end. When the gauze strip is broken by the limit tension, the first motor 202 stops rotating, and the tension sensor 208 transmits the limit tension data to the computer end. The obtained tension test result is accurate, which avoids the gauze strip from breaking at the clamping block 304, and at the same time improves the fixing efficiency of the end of the gauze strip. The setting of the guide column 205 improves the stability of the lifting plate 204 sliding up and down; Then, when it is necessary to adjust the position of the upper clamping block 304, the limit strip 402 can be pulled, and the limit strip 402 drives the fixed block 404 to slide together, the tension spring 406 is extended, and the limit strip 402 is no longer engaged with the limit groove 403 on the stand 201. At this time, the connecting frame 401 can be slid up and down, and the connecting frame 401 drives the mounting plate 207 to slide up and down together, driving the tension sensor 208, the mounting strip 209, the sliding strip 210 and the upper clamping block 304 to move up and down together. After adjusting to the appropriate position, the limit strip 402 can be released, and the tension spring 406 is reset to drive the limit strip 402 to engage with other limit grooves 403 on the stand 201, thereby quickly adjusting the maximum distance between the upper and lower clamping blocks 304, which is convenient for detecting gauze strips of different lengths. The setting of the fixing rod 405 improves the sliding stability of the fixed block 404 and prevents the limit strip 402 from slipping off. Secondly, when it is necessary to test multiple gauze strip samples, the placement box 601 can be placed flat on the desktop first, and then the pull bar 610 is pulled, and the pull bar 610 drives multiple connecting strips 608 to slide. The setting of the guide rod 609 improves the sliding stability of the connecting strip 608. The sliding of the connecting strip 608 drives the mounting frame 604 to slide, and the sliding of the mounting frame 604 drives the connecting plate 606 to move. The second spring 607 is compressed, and then the rotating rod 612 on the rotating shaft 611 is rotated. After rotating ninety degrees, the rotating rod 612 is inserted into the socket 613 to prevent the connecting strip 608 and the mounting frame 604 from being slid under the elastic force of the second spring 607. After the cloth is put back into place, the space for placing the gauze strips in the placing groove 602 is relatively large. Multiple gauze strips are placed in the placing groove 602 in sequence, so that the gauze strips are between the first guide roller 603 and the second guide roller 605. Then the pull bar 610 is pulled to separate the rotating rod 612 from the plug hole 613. Then the rotating rod 612 is rotated to make it in a vertical state. At this time, the pull bar 610 is released, and the multiple second springs 607 are reset to drive the multiple connecting plates 606 and the mounting bracket 604 to reset. The mounting bracket 604 pushes the second guide roller 605 to move, and then cooperates with the first guide roller 603 to preliminarily clamp and fix the multiple gauze strips to be tested. Then The placement box 601 is installed on the support frame 501. First, align the slider 503 on one side of the placement box 601 with the guide groove 502 on the support frame 501, and then slide it in. After partially sliding in, you can pull the two pull rods 508, the pull rods 508 drive the plug block 506 to rise, the first spring 509 is compressed, and the placement box 601 and the slider 503 are continued to be pushed in until the plug block 506 is directly above the push block 505, release the two pull rods 508, the first spring 509 resets and drives the plug block 506 to plug with the push block 505. At this time, the placement box 601 is installed. When the clamping structure detects and draws out a gauze strip inside the placement slot 602, After the detection is completed, the second hydraulic rod 701 drives the slide bar 210 to return to the inside of the installation bar 209, and then starts the first hydraulic rod 504. The first hydraulic rod 504 pushes the push block 505, the insert block 506, the pull rod 508, the fixed plate 507 and the placement box 601 to move, and then the next placement slot 602 and the gauze strip to be tested in the placement slot 602 are pulled to one side of the slide bar 210, and then the second hydraulic rod 701 is started to make the clamping blocks 304 on the slide bar 210 on both sides of the gauze strip to be tested, and then the clamping detection operation is performed, and this reciprocating operation realizes the rapid and automatic feeding of the gauze strips and improves the detection efficiency; Finally, when the second hydraulic rod 701 drives the slide bar 210 to slide, the guide block 706 on the slide bar 210 slides out of the first slide groove 703 on the mounting strip 209, the third spring 709 is reset, thereby driving the connecting rods 708 on both sides of the gauze strip to slide toward each other, the connecting rod 708 drives the slide 704 to slide toward each other, the slide 704 drives the clamping roller 705 to move, and the two clamping rollers 705 clamp the gauze strip, so that when the clamping block 304 below clamps the gauze strip and pulls it downward, the gauze strip can maintain a certain tension to prevent the gauze strip from falling loose during loading, and when the gauze strip is completely withdrawn from the inside of the placement box 601, it will not bend, and then the gauze strip is clamped by the clamping structure above, and then the tensile performance test is carried out to prevent the gauze strip from wrinkling at the end when clamping, and when the test is completed, the gauze strip sample that has been tested is removed, and then After that, the second hydraulic rod 701 contracts and drives the push plate 702 and the slide bar 210 to slide. Since the entrance of the first slide groove 703 is a trapezoidal structure, after the guide block 706 conflicts with the inclined position of the first slide groove 703, when the second hydraulic rod 701 continues to be contracted, when the slide bar 210 continues to slide, the two guide blocks 706 will slide horizontally and backwards in the second slide groove 707, thereby driving the slide 704 to slide backwards, and the slide 704 drives the connecting rod 708 to slide backwards, the third spring 709 is compressed, and the distance between the two clamping rollers 705 increases. In this way, when the slide bar 210 slides out of part of the position of the mounting strip 209, due to the large distance between the clamping rollers 705, it can move smoothly to the two sides of the gauze strip until the guide block 706 completely slides out, and the first slide groove 703 loses its resistance to the guide block 706, and the third spring 709 can be reset to drive the clamping roller 705 to clamp the gauze strip.
