Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a textile tensile strength testing device. Background Technology

[0002] Textiles are products made through textile processing. They include yarns, woven fabrics, knitted fabrics, and braided fabrics. During the production of some elastic fabrics, it is necessary to stretch the fabric to check its tensile strength and whether it meets the standards. Generally, a section of a roll of fabric is cut and taken out separately for tensile testing. Because it is elastic fabric, if the test is passed, the fabric will spring back and can be recycled for further processing. However, the recycling value of cut fabric is not high. Therefore, non-shear tensile testing of multiple sections of rolled fabric is more practical.

[0003] When stretching a roll of fabric, it is necessary to limit and fix the stretching point. Compared with stretching a single piece of fabric, the roll of fabric has more fabric wound on the left roller and less on the right roller, so the fabric will be inclined in the middle. In this case, fixing the inclined fabric with a horizontal clamp will result in poor fixing effect. Therefore, a textile tensile strength testing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a textile tensile strength testing device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a textile tensile strength testing device, comprising a housing, a support plate slidably connected to the inner wall of the housing, a movable block fixedly connected to the side of the support plate away from the housing, a bidirectional screw threadedly connected to the inner wall of the movable block, two guide posts slidably connected to the inner wall of the movable block, a pressure rod rotatably connected to the inner wall of the top of the support plate via a torsion spring, a roller rotatably connected to the side of the support plate away from the housing, an upper clamping plate fixedly connected to the end of the pressure rod away from the support plate, a top rod rotatably connected to the inner wall of the top of the support plate, a lower clamping plate rotatably connected to the end of the top rod away from the support plate, and a connecting rod connecting the front and rear of the lower clamping plate. A transmission rod is fixedly connected, and a transmission roller is rotatably connected to the lower surface of the transmission rod. When the fabric wound on the left roller is thicker than that on the right roller, the fabric is in an inclined state. The fabric on the roller will push the transmission roller up, and the transmission roller will push the transmission rod to rotate. The transmission rod will drive the lower clamping plate to rotate, and the lower clamping plate will drive the upper clamping plate to rotate together, so that the upper and lower clamping plates are always parallel to the fabric, increasing the contact area between the fabric and the clamping plates, thereby improving the fabric fixing effect. The two ends of the bidirectional screw are rotatably connected to the inner wall of the box, the two ends of the guide post are fixedly connected to the inner wall of the box, the lower surface of the moving block is slidably connected to the bottom wall inside the box, and the roller is located above the moving block.

[0006] Preferably, the surface of the movable block is provided with a dust removal device, which includes an elastic plate. A transmission plate is fixedly connected to the upper surface of the elastic plate, and a rotating rod is rotatably connected to the top of the transmission plate. Two fixed plates are fixedly connected to the upper surface of the elastic plate, and a rotating shaft is rotatably connected between the two fixed plates. A protruding rod is fixedly connected to the surface of the rotating shaft. An external motor drives a bidirectional screw to rotate, which in turn drives the movable block to move separately and, through a support plate, drives two rollers to move separately to pull the fabric for tensile strength testing. After the test, the motor reverses, causing the bidirectional screw to bring the two movable blocks together. The elastic plate is deformed by compression, and the arching deformation of the elastic plate drives the transmission plate to rotate outward, causing the rotating rod on the transmission plate to contact the roller. As the roller rotates and moves the fabric, it also drives the rotating rod to rotate. The rotating rod drives the shaft to rotate via the conveyor belt, and the shaft drives the convex rod to rotate. The convex rod beats the moving fabric. Since the fabric is just stretched and in contact, the mesh on the fabric is stretched and enlarged. At this time, the dust in the gaps of the fabric can be knocked off by the knocking vibration, achieving deep cleaning of the dust. The surface of the rotating rod is connected to the surface of the shaft via the conveyor belt, and the two sides of the elastic plate are fixedly connected to the surfaces of the two moving blocks.

[0007] Preferably, a collecting device is provided on the lower surface of the elastic plate. The collecting device includes a connecting rod, a collecting box rotatably connected to the surface of the connecting rod, a sliding plate slidably connected to the inner wall of the elastic plate, and a baffle fixedly connected to the upper surface of the elastic plate. Dust falls onto the elastic plate, and when the protruding rod rotates, it pushes the sliding plate downward. The sliding plate hits the collecting box, and the collecting box transmits the vibration to the elastic plate through the connecting rod. At this time, the dust on the elastic plate falls into the collecting box along the baffle, so that the dust can be collected and prevented from being stirred up again onto the fabric. At the same time, the vibration of the collecting box can make the dust particles more compact, thereby collecting more dust. The top of the connecting rod is rotatably connected to the lower surface of the elastic plate, and a spring is fixedly connected to the surface of the sliding plate. The end of the spring away from the sliding plate is fixedly connected to the lower surface of the elastic plate.

[0008] Preferably, the surface of the lower clamping plate is provided with a recovery device, which includes a connecting plate. A rotating plate is rotatably connected to the surface of the connecting plate, and an ironing plate is fixedly connected to the surface of the pressure rod. When the fabric moves and is stretched in multiple parts, the fabric, after dust removal, will slide between the rotating plate and the ironing plate. At this time, the ironing plate will iron the fabric, accelerating its rebound and recovery. Simultaneously, the fabric on the right roller will thicken after the fabric moves. At this time, the lower clamping plate will be driven to rotate by the transmission rod, but the rotating plate and the ironing plate are tightly fitted together. Therefore, the rotating plate will rotate between the connecting plate fixed on the lower clamping plate to prevent the rotating plate and the lower clamping plate from rotating together, which would result in incomplete ironing of the fabric. The lower surface of the ironing plate is in contact with the upper surface of the rotating plate through the fabric, and the surface of the connecting plate is fixedly connected to the surface of the lower clamping plate.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. In this textile tensile strength testing equipment, when the fabric wound on the left roller is thicker than that on the right roller, the fabric is in an inclined state. The fabric on the roller will lift the transmission roller, which will push the transmission rod to rotate. The transmission rod will drive the lower clamping plate to rotate, and the lower clamping plate will drive the upper clamping plate to rotate together, so that the upper and lower clamping plates are always parallel to the fabric, increasing the contact area between the fabric and the clamping plates, thereby improving the fixing effect of the fabric.

[0010] 2. After the textile tensile strength testing equipment is completed, the motor reverses, causing the bidirectional screw to drive two moving blocks to converge and compress the elastic plate, causing it to deform. The deformed elastic plate arches and drives the transmission plate to rotate outward, causing the rotating rod on the transmission plate to contact the roller. As the roller rotates and moves the fabric, it also drives the rotating rod to rotate. The rotating rod drives the shaft to rotate via the conveyor belt, and the shaft drives the convex rod to rotate. The convex rod beats the moving fabric. Since the fabric is just stretched and in contact, the mesh on the fabric will be stretched and enlarged. At this time, through the knocking and vibration, the dust in the gaps of the fabric can be knocked off, achieving deep cleaning of the dust.

[0011] 3. In this textile tensile strength testing device, dust falls onto the elastic plate. When the convex rod rotates, it pushes the slide plate downward. The slide plate hits the collection box, and the collection box transmits the vibration to the elastic plate through the connecting rod. At this time, the dust on the elastic plate falls into the collection box along the baffle, so that the dust can be collected and prevented from being stirred up again onto the fabric. At the same time, the vibration of the collection box can make the dust particles more compact, thus collecting more dust.

[0012] 4. In this textile tensile strength testing equipment, when the fabric moves and is stretched in multiple parts, the fabric, after dust removal, will slide between the rotating plate and the ironing plate. At this time, the ironing plate will iron the fabric to accelerate its rebound and recovery. At the same time, the fabric on the right roller will become thicker after the fabric moves. At this time, the lower clamping plate will be driven to rotate by the transmission rod. However, the rotating plate and the ironing plate are tightly attached. Therefore, the rotating plate will rotate between the connecting plate fixed on the lower clamping plate to prevent the rotating plate and the lower clamping plate from rotating together, which would result in incomplete ironing of the fabric.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0016] A textile tensile strength testing device, such as Figures 1-6 As shown, the device includes a housing 1. A support plate 2 is slidably connected to the inner wall of the housing 1. A movable block 3 is fixedly connected to the side of the support plate 2 away from the housing 1. A double-ended screw 31 is threadedly connected to the inner wall of the movable block 3. Two guide posts 32 are slidably connected to the inner wall of the movable block 3. A pressure rod 6 is rotatably connected to the inner wall of the top of the support plate 2 via a torsion spring. A roller 8 is rotatably connected to the side of the support plate 2 away from the housing 1. An upper clamping plate 9 is fixedly connected to the end of the pressure rod 6 away from the support plate 2. A top rod 10 is rotatably connected to the inner wall of the top of the support plate 2. A lower clamping plate 11 is rotatably connected to the end of the top rod 10 away from the support plate 2. A transmission rod 12 is fixedly connected to the front and rear of the lower clamping plate 11 via connecting rods. The lower surface of the transmission rod 12 is rotatably connected to... There is a drive roller 13. When the fabric wound on the left roller 8 is thicker than that on the right roller 8, the fabric is in an inclined state. The fabric on the roller 8 will push the drive roller 13 up. The drive roller 13 will push the drive rod 12 to rotate. The drive rod 12 will drive the lower clamping plate 11 to rotate. The lower clamping plate 11 will drive the upper clamping plate 9 to rotate together, so that the upper clamping plate 9 and the lower clamping plate 11 are always parallel to the fabric, increasing the contact area between the fabric and the clamping plate, thereby improving the fixing effect of the fabric. The two ends of the bidirectional screw 31 are rotatably connected to the inner wall of the box 1. The two ends of the guide post 32 are fixedly connected to the inner wall of the box 1. The lower surface of the moving block 3 is slidably connected to the bottom wall inside the box 1. The roller 8 is located above the moving block 3.

[0017] Preferably, the surface of the movable block 3 is provided with a dust removal device 4. The dust removal device 4 includes an elastic plate 41, a transmission plate 42 is fixedly connected to the upper surface of the elastic plate 41, a rotating rod 43 is rotatably connected to the top of the transmission plate 42, two fixed plates 44 are fixedly connected to the upper surface of the elastic plate 41, a rotating shaft 45 is rotatably connected between the two fixed plates 44, and a protruding rod 46 is fixedly connected to the surface of the rotating shaft 45. An external motor drives the bidirectional screw 31 to rotate, which in turn drives the movable block 3 to move separately and, through the support plate 2, drives the two rollers 8 to move separately to pull the fabric for tensile strength testing. After the test, the motor reverses, causing the bidirectional screw 31 to drive the two movable blocks 3 to converge and compress the elastic plate 3. When the elastic plate 41 deforms and arches, it drives the transmission plate 42 to rotate outward, causing the rotating rod 43 on the transmission plate 42 to contact the roller 8. As the roller 8 rotates and moves the fabric, it drives the rotating rod 43 to rotate. The rotating rod 43 drives the rotating shaft 45 to rotate via the conveyor belt. The rotating shaft 45 drives the convex rod 46 to rotate. The convex rod 46 beats the moving fabric. Since the fabric is just stretched and in contact, the mesh on the fabric will be stretched and enlarged. At this time, the dust in the gaps of the fabric can be knocked off by the knocking vibration, achieving deep cleaning of the dust. The surface of the rotating rod 43 is connected to the surface of the rotating shaft 45 via the conveyor belt. The two sides of the elastic plate 41 are fixedly connected to the surfaces of the two moving blocks 3.

[0018] Preferably, a collecting device 5 is provided on the lower surface of the elastic plate 41. The collecting device 5 includes a connecting rod 51, a collecting box 52 is rotatably connected to the surface of the connecting rod 51, a sliding plate 53 is slidably connected to the inner wall of the elastic plate 41, and a baffle 54 is fixedly connected to the upper surface of the elastic plate 41. Dust will fall on the elastic plate 41. When the protruding rod 46 rotates, it will push the sliding plate 53 downward. The sliding plate 53 will hit the collecting box 52. The collecting box 52 will transmit the vibration to the elastic plate 41 through the connecting rod 51. At this time, the dust on the elastic plate 41 will fall into the collecting box 52 along the baffle 54, so that the dust can be collected and prevented from being raised again to the fabric. At the same time, the vibration of the collecting box 52 can make the dust particles more compact, thereby collecting more dust. The top of the connecting rod 51 is rotatably connected to the lower surface of the elastic plate 41, and a spring is fixedly connected to the surface of the sliding plate 53. The end of the spring away from the sliding plate 53 is fixedly connected to the lower surface of the elastic plate 41.

[0019] Preferably, the surface of the lower clamping plate 11 is provided with a recovery device 7, which includes a connecting plate 71. A rotating plate 72 is rotatably connected to the surface of the connecting plate 71, and an ironing plate 73 is fixedly connected to the surface of the pressure rod 6. When the fabric moves and is stretched in multiple parts, the fabric will slide between the rotating plate 72 and the ironing plate 73 after dust removal. At this time, the ironing plate 73 will iron the fabric to accelerate its rebound and recovery. At the same time, the fabric on the right roller 8 will become thicker after the fabric moves. At this time, the lower clamping plate 11 will be driven to rotate by the transmission rod 12. However, the rotating plate 72 and the ironing plate 73 are tightly attached. Therefore, the rotating plate 72 will rotate between the connecting plate 71 fixed on the lower clamping plate 11 to prevent the rotating plate 72 from rotating together with the lower clamping plate 11, which would result in incomplete ironing of the fabric. The lower surface of the ironing plate 73 is in contact with the upper surface of the rotating plate 72 through the fabric, and the surface of the connecting plate 71 is fixedly connected to the surface of the lower clamping plate 11.

[0020] Working principle: When the fabric wound on the left roller 8 is thicker than that on the right roller 8, the fabric is in an inclined state. The fabric on the roller 8 will lift the transmission roller 13, which will push the transmission rod 12 to rotate. The transmission rod 12 will drive the lower clamping plate 11 to rotate, and the lower clamping plate 11 will drive the upper clamping plate 9 to rotate together, so that the upper clamping plate 9 and the lower clamping plate 11 are always parallel to the fabric, increasing the contact area between the fabric and the clamping plate, thereby improving the fixing effect of the fabric. The external motor drives the bidirectional screw 31 to rotate, which in turn drives the moving block 3 to move separately and, through the support plate 2, drives the two rollers 8 to move separately to pull the fabric for tensile strength testing. After the test, the motor reverses, causing the bidirectional screw 31 to drive the two moving blocks 3 to converge and squeeze the elastic plate 41 to deform. The deformation of the elastic plate 41 causes the transmission plate 42 to rotate outward, so that the rotating rod 43 on the transmission plate 42 contacts the rollers 8. As the rollers 8 rotate and move the fabric, they also drive the rotating rod 43 to rotate. The rotating rod 43 drives the rotating shaft 45 to rotate through the conveyor belt. The rotating shaft 45 drives the convex rod 46 to rotate. The convex rod 46 beats the moving fabric. Since the fabric is just stretched and in contact, the mesh on the fabric will be stretched and enlarged. At this time, the dust in the gaps of the fabric can be knocked off by the knocking vibration, achieving deep cleaning of the dust. Dust will fall onto the elastic plate 41. When the convex rod 46 rotates, it will push the slide plate 53 downward. The slide plate 53 will hit the collection box 52. The collection box 52 will transmit the vibration to the elastic plate 41 through the connecting rod 51. At this time, the dust on the elastic plate 41 will fall into the collection box 52 along the baffle 54, so that the dust can be collected and prevented from being raised back onto the fabric. At the same time, the vibration of the collection box 52 can make the dust particles more compact, thus collecting more dust. When the fabric moves and is stretched in multiple parts, after dust removal, the fabric will slide between the rotating plate 72 and the ironing plate 73. At this time, the ironing plate 73 will iron the fabric to accelerate its rebound and recovery. Meanwhile, the fabric on the right roller 8 will become thicker after the fabric moves. At this time, the lower clamping plate 11 will be driven to rotate by the transmission rod 12. However, the rotating plate 72 and the ironing plate 73 are tightly attached. Therefore, the rotating plate 72 will rotate with the connecting plate 71 fixed on the lower clamping plate 11 to prevent the rotating plate 72 and the lower clamping plate 11 from rotating together, which would result in incomplete ironing of the fabric.
