Description

Technical Field

[0001] The present invention belongs to the technical field of textile fabric detection, and specifically relates to a tensile strength testing device for textile fabrics. Background Art

[0002] After the textile fabric is processed by fabric equipment, its tensile strength needs to be detected. The detection method is to clamp both ends of the fabric to be detected on the upper and lower ends of the testing machine through a clamping mechanism respectively. The upper end of the testing machine is the power end, and the lower end is the fixed end. During the test, the top power end pulls the fabric upward for stretching. According to the tensile force borne by the fabric when it is stretched to plastic deformation, the tensile strength of the fabric can be obtained. Such testing machines are all equipped with a digital display testing terminal, which is connected to the power end and used to display the above test data.

[0003] A patent application with the publication number CN118392664B discloses a tensile strength detection device for textile fabrics. By setting a water tank, filling the water tank with water in advance, then stretching the fabric through a stretching mechanism, and then pushing the pressing plate downward by pressing the lever, the water in the water tank flows onto the fabric through the water outlet pipe. After the water penetrates the fabric, it drips into the aggregation tank and then flows down through the drain port. At this time, just observe the water flow at the drain port. If the water flow is larger at a certain place, it means that the fabric has been torn at the corresponding position above the water flow. If there is no obvious difference in the water flow at the drain port, it means that the fabric has not been torn and can be stretched continuously, so as to obtain a more accurate tensile test result.

[0004] In the above prior art, by pouring water onto the upper end of the textile fabric and then conducting a tensile test on the fabric, and judging the tearing degree of the textile fabric by observing the water flow rate. When conducting a tensile test on a waterproof fabric, since the fabric is placed horizontally, when pouring water onto the upper end of the fabric, the water above the fabric will slide off from the side, and it is necessary to keep adding water to the upper end of the fabric. The impact force of the falling water during water addition may affect the result of the fabric tensile test.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0022] Embodiment 1: As Figures 1-3 shown, a textile fabric tensile strength testing device according to an embodiment of the present invention includes two groups of first arc-shaped clamping plates 1. Each group of first arc-shaped clamping plates 1 includes two first arc-shaped clamping plates 1. The first arc-shaped clamping plates 1 are used for clamping textile fabrics. First rectangular blocks 11 are fixedly connected to both sides of the first arc-shaped clamping plates 1. Opposite first rectangular blocks 11 slide on one side of the first rectangular strips 111 respectively. The first rectangular strips 111 are rotatably arranged on one side of the first support blocks 12 respectively. Rectangular plates 13 are fixedly connected to the lower ends of opposite first support blocks 12. A pipe 2 is arranged above the first arc-shaped clamping plates 1. A rectangular collection box 3 is arranged below the pipe 2.

[0023] Specifically, when performing a tensile strength test on a waterproof fabric, it is necessary to observe the waterproof performance of the waterproof fabric during the tensile test. By pouring water on the upper end of the fabric and then stretching it to observe whether the water penetrates the fabric and to determine whether the fabric is torn, so as to judge the waterproof performance of the waterproof fabric. The fabric is horizontally placed during stretching. When pouring water on the upper end of the waterproof fabric, the water will slide off from the upper end of the fabric, and it is necessary to keep adding water above the fabric all the time. The impact force of the falling water during water addition may affect the result of the tensile test of the fabric. When using this test device, drive the first rectangular block 11 to slide on one side of the first rectangular bar 111, drive the two groups of first arc-shaped clamping plates 1 to clamp both ends of the fabric, so that an arc surface is formed at the upper end of the fabric, which can hold the water at the upper end of the fabric and make the water stay at the upper end of the fabric. Then drive the two rectangular plates 13 to slide in opposite directions, drive the two groups of first arc-shaped clamping plates 1 to slide in opposite directions respectively through the first support block 12, and stretch the clamped waterproof fabric. While stretching, rotate the first rectangular bar 111 to drive the two groups of first arc-shaped clamping plates 1 to rotate in opposite directions at the same time, so as to pull the lowest point of the arc surface of the clamped waterproof fabric, so that the lowest point of the arc surface receives the greatest tensile force, and the water is inside the arc surface formed by the fabric. When the fabric is torn, ensure that the water can penetrate the fabric immediately, so as to accurately detect the result of the tensile strength test of the waterproof fabric, and detect at what strength the waterproof fabric will be torn and cause the waterproof effect to disappear. By setting the first arc-shaped clamping plate 1 to clamp the fabric to form an arc surface, the water at the upper end can be held. During the test, there is no need to keep adding water above the fabric all the time, and rotating the first rectangular bar 111 to stretch the lowest end of the fabric arc makes the tensile force at the lower end of the fabric arc the greatest. When the fabric is torn, the water at the upper end of the fabric can penetrate the fabric immediately, and the tearing time of the fabric can be determined immediately, making the test result more accurate, and solving the problem that when testing the strength and waterproof performance of the waterproof fabric by adding water, the fabric is horizontally placed, the water above the fabric will slide off from the side, and it is necessary to keep adding water above the fabric all the time, and the impact force of the falling water during water addition may affect the result of the tensile test of the fabric.

[0024] As Figure 4 shown, the lower ends of the first rectangular bar 111 are respectively rotatably connected with first connecting rods 14, the ends of the first connecting rods 14 far from the first rectangular bar 111 are respectively rotatably connected with second rectangular bars 141, two opposite second rectangular bars 141 are jointly slidably arranged in the middle of the first rectangular cylinder 142, the lower ends of the second rectangular bars 141 are respectively fixedly connected with third rectangular bars 144 through telescopic rods 143, the third rectangular bars 144 are respectively fixedly connected to the upper ends of the rectangular plates 13, two opposite third rectangular bars 144 are respectively slidably arranged in the middle of the second rectangular cylinder 145, and the lower ends of the rectangular plates 13 are slidably arranged with first slide rails 133, and the lower ends of the first slide rails 133 are fixedly connected to the bottom plate 6.

[0025] Specifically, when the fabric is pulled, the two rectangular plates 13 slide in opposite directions at the upper end of the first slide rail 133. The rectangular plates 13 respectively drive the third rectangular strips 144 to slide in opposite directions at both ends in the second rectangular cylinder 145. The third rectangular strips 144 drive the second rectangular strips 141 to slide in opposite directions at both ends of the first rectangular cylinder 142 through the telescopic rods 143. The second rectangular strips 141 drive the first rectangular strip 111 to slide to both sides through the first connecting rods 14. The first rectangular strip 111 drives the two groups of first arc-shaped clamping plates 1 to slide, stretching the fabric. At the same time, by driving the telescopic rods 143 to extend, the first rectangular cylinder 142 can be driven to move upward. The first rectangular cylinder 142 drives the first connecting rod 14 to rotate through the second rectangular strip 141, thereby driving the first rectangular strip 111 to rotate. When the first rectangular strip 111 rotates, it drives the two groups of first arc-shaped clamping plates 1 to rotate in opposite directions at the same time, pulling the lowest point of the arc surface of the clamped waterproof fabric, so that the tensile force received at the lower end of the fabric arc surface is the largest.

[0026] As Figure 5 shown, on both sides between the first rectangular cylinder 142 and the second rectangular cylinder 145, there are respectively connecting rod groups. The connecting rod groups include second connecting rods 146 respectively rotatably connected to one side of the first rectangular cylinder 142. One end of the second connecting rod 146 away from the first rectangular cylinder 142 is rotatably connected to a third connecting rod 147. One side of the third connecting rod 147 is rotatably connected to one side of the second rectangular cylinder 145. A fourth rectangular strip 148 is rotatably connected between the two opposite groups of second connecting rods 146 and third connecting rods 147.

[0027] Specifically, when the rectangular plate 13 drives the first arc-shaped clamping plate 1 to move to both sides through the first support block 12, at the same time, two fourth rectangular strips 148 are driven to move in opposite directions at the same time. The fourth rectangular strips 148 drive the second connecting rods 146 and the third connecting rods 147 to rotate at the same time. When the second connecting rods 146 and the third connecting rods 147 rotate, they drive the first rectangular cylinder 142 to move upward. The first rectangular cylinder 142 drives the first connecting rod 14 to rotate through the second rectangular strip 141, thereby driving the first rectangular strip 111 to rotate and stretching the fabric.

[0028] As Figure 5 shown, on one side of the fourth rectangular strip 148, there are respectively fixed fifth rectangular strips 15. One end of the fifth rectangular strip 15 is respectively fixed with a second rack 152. A gear 131 is rotatably arranged in the middle of the rectangular plate 13. One side of the gear 131 is engaged with the second rack 152. The other side of the gear 131 is engaged with a first rack 132. The first rack 132 is fixed to the upper end of the rectangular plate 13.

[0029] Specifically, when the rectangular plate 13 slides to both sides, it drives the gear 131 to rotate on one side of the first rack 132. While the gear 131 rotates, it drives the second rack 152 to move to one side. The second rack 152 drives the fourth rectangular bar 148 to move to both sides through the fifth rectangular bar 15. The fourth rectangular bar 148 drives the second connecting rod 146 and the third connecting rod 147 to rotate simultaneously, thereby driving the first rectangular bar 111 to rotate and stretching the fabric.

[0030] As Figures 6-7 shown, a rolled fabric 4 is provided on one side of the upper end of the bottom plate 6. A clamping assembly is provided on one side of the rolled fabric 4. The clamping assembly includes two second arc-shaped clamping plates 41. Second rectangular blocks 42 are fixedly connected to both ends of the second arc-shaped clamping plate 41. A second support block 45 is slidably connected to the side of the second rectangular block 42. The second support block 45 is fixedly connected to the upper end of the bottom plate 6. Third arc-shaped clamping plates 43 are respectively provided on one side of the second arc-shaped clamping plate 41. Third rectangular blocks 431 are slidably connected to both sides of the third arc-shaped clamping plate 43. A magnet 432 is fixedly connected to one side of the third arc-shaped clamping plate 43. A rope 442 is fixedly connected to the side of the third rectangular block 431. A cylindrical bar 5 is slidably provided on the other side of the upper end of the bottom plate 6.

[0031] Specifically, the same batch of fabrics needs to be tested multiple times. Pull out the end of the rolled fabric 4 and place it between the second arc-shaped clamping plates 41, and then pull it to between the third arc-shaped clamping plates 43 for clamping. Then drive the first arc-shaped clamping plates 1 to move away from each other. Then drive the cylindrical bar 5 to pass through between each of the first arc-shaped clamping plates 1. The cylindrical bar 5 approaches the third arc-shaped clamping plate 43, so that the end of the cylindrical bar 5 adsorbs to the magnet 432. Then drive the cylindrical bar 5 to move to the side away from the second arc-shaped clamping plate 41, driving the end of the fabric clamped in the middle of the third arc-shaped clamping plate 43 to pass through between each of the first arc-shaped clamping plates 1, driving the fabric to be located between each of the first arc-shaped clamping plates 1. Then drive the first arc-shaped clamping plates 1 to clamp the fabric, and tensile tests can be carried out at any time. The fabric can be automatically pulled, and continuous tests on the fabric can be carried out.

[0032] As Figure 7 shown, arc-shaped bevel blocks 412 are respectively slidably provided inside one side of the second arc-shaped clamping plates 41. The arc-shaped bevel blocks 412 are fixedly connected to the inside of the second arc-shaped clamping plates 41 through second springs 411.

[0033] Specifically, after the test on a piece of fabric is completed, the third arc-shaped clamping plate 43 is started to slide towards both sides, driving the second arc-shaped clamping plate 41 to drive the end of the fabric to move between the third arc-shaped clamping plates 43, so that the arc-shaped bevel block 412 is located between the third arc-shaped clamping plates 43. Subsequently, the third arc-shaped clamping plate 43 is driven to approach the fabric and slide along the bevel of the arc-shaped bevel block 412, causing the arc-shaped bevel block 412 to slide into the second arc-shaped clamping plate 41 and compress the second spring 411. Then, the end of the fabric is clamped. Subsequently, the cylindrical bar 5 is driven to drive the third arc-shaped clamping plate 43 to pull the fabric to between the first arc-shaped clamping plates 1, and then a new round of tensile test can be carried out on the fabric.

[0034] As Figure 7 shown, the rope 442 passes through the second rectangular block 42. The rope 442 is wound around the outside of the runner 44. The runner 44 is connected to the L-shaped block 441 through a torsion spring. The L-shaped block 441 is fixedly connected to the second support block 45.

[0035] Specifically, when the cylindrical bar 5 drives the third arc-shaped clamping plate 43 to pull the fabric to between the first arc-shaped clamping plates 1, the third arc-shaped clamping plate 43 pulls out the rope 442, and the rope 442 drives the runner 44 to rotate. When the third arc-shaped clamping plate 43 moves to one side of the second arc-shaped clamping plate 41, the torsion spring drives the runner 44 to rotate and drive the rope 442 to wind around the outside of the runner 44.

[0036] As Figure 6 shown, a cutting knife 46 is slidably arranged between two second support blocks 45. The cutting knife 46 is located between the second arc-shaped clamping plate 41 and the third arc-shaped clamping plate 43. A knife seat 47 is arranged at the lower end of the cutting knife 46.

[0037] Specifically, after the fabric is pulled to between the first arc-shaped clamping plates 1, the cutting knife 46 and the knife seat 47 are driven to slide to cut the fabric, which is convenient for continuously carrying out tensile tests on the fabric.

[0038] Embodiment 2: As Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is: the four corners of the lower end of the rectangular collection box 3 are respectively rotatably connected with sixth rectangular strips 31. One side of the rectangular collection box 3 is fixedly connected with a drain pipe 34. The lower ends of the sixth rectangular strips 31 are slidably arranged inside the third rectangular cylinder 33. The sixth rectangular strips 31 are fixedly connected inside the third rectangular cylinder 33 through first springs 32. The third rectangular cylinder 33 is rotatably arranged on the upper end of the bottom plate 6.

[0039] Specifically, when carrying out a tensile test on the fabric, when the fabric tears, water passes through the fabric and falls into the rectangular collection box 3 for centralized collection. By pressing one side of the rectangular collection box 3 downward, the sixth rectangular strip 31 on one side of the rectangular collection box 3 slides towards one side of the third rectangular cylinder 33 and compresses the first spring 32. Then, the water in the rectangular collection box 3 is discharged from the drain pipe 34 on one side.

[0040] As Figure 9 shown, the cylindrical bar 5 is slidably arranged inside the rectangular frame 51. A bevel block 52 is fixedly connected to the lower end of the rectangular frame 51, and a support column 53 is fixedly connected to the lower end of the rectangular frame 51. The lower end of the support column 53 is slidably connected to a second slide rail 54, and the second slide rail 54 is fixedly connected to the upper end of the bottom plate 6.

[0041] Specifically, when the support column 53 drives the rectangular frame 51 to approach the first arc-shaped clamping plate 1, it simultaneously drives the bevel block 52 to squeeze the rectangular collection box 3 downward, causing the rectangular collection box 3 to tilt and drain the water inside the rectangular collection box 3. Subsequently, the cylindrical bar 5 is driven to slide inside the rectangular frame 51 towards the side close to the first arc-shaped clamping plate 1 until it slides to the side of the third arc-shaped clamping plate 43, thereby driving the third arc-shaped clamping plate 43 to slide towards the side close to the rectangular frame 51, and the fabric can be pulled between the first arc-shaped clamping plates 1.

[0042] Working principle: Pull out the end of the rolled fabric 4 and place it between the second arc-shaped clamping plates 41, then pull it to between the third arc-shaped clamping plates 43 for clamping. Subsequently, drive the first arc-shaped clamping plates 1 to move away from each other. Then drive the cylindrical bar 5 to pass through between each of the first arc-shaped clamping plates 1. The cylindrical bar 5 approaches the third arc-shaped clamping plate 43, so that the end of the cylindrical bar 5 is adsorbed by the magnet 432. Then drive the cylindrical bar 5 to move to the side away from the second arc-shaped clamping plate 41, driving the end of the fabric clamped in the middle of the third arc-shaped clamping plate 43 to pass through between each of the first arc-shaped clamping plates 1, driving the fabric to be located between each of the first arc-shaped clamping plates 1. Then drive the first arc-shaped clamping plates 1 to clamp the fabric, drive the first rectangular block 11 to slide on one side of the first rectangular strip 111, driving the two groups of first arc-shaped clamping plates 1 to clamp the two ends of the fabric, so that the upper end of the fabric forms an arc surface. Then inject water onto the upper end of the fabric through the pipe 2. The rectangular plate 13 slides in opposite directions on the upper end of the first slide rail 133. The rectangular plate 13 respectively drives the third rectangular strip 144 to slide in opposite directions at both ends in the second rectangular cylinder 145. The third rectangular strip 144 drives the second rectangular strip 141 to slide in opposite directions at both ends of the first rectangular cylinder 142 through the telescopic rod 143. The second rectangular strip 141 drives the first rectangular strip 111 to slide to both sides through the first connecting rod 14. The first rectangular strip 111 respectively drives the two groups of first arc-shaped clamping plates 1 to slide, stretching the fabric. When the rectangular plate 13 slides to both sides, it drives the gear 131 to rotate on one side of the first rack 132. While the gear 131 rotates, it drives the second rack 152 to move to one side. The second rack 152 drives the fourth rectangular strip 148 to move to both sides through the fifth rectangular strip 15. The fourth rectangular strip 148 drives the second connecting rod 146 and the third connecting rod 147 to rotate simultaneously. While the second connecting rod 146 and the third connecting rod 147 rotate, they drive the first rectangular cylinder 142 to move upward. The first rectangular cylinder 142 drives the first connecting rod 14 to rotate through the second rectangular strip 141, thereby driving the first rectangular strip 111 to rotate. While the first rectangular strip 111 rotates, it drives the two groups of first arc-shaped clamping plates 1 to rotate in opposite directions simultaneously, pulling the lowest point of the arc surface of the clamped waterproof fabric, so that the pulling force received at the lower end of the fabric arc surface is the largest. After the fabric is torn, the water passes through the fabric and remains in the rectangular collection box 3. When the support column 53 drives the rectangular frame 51 to approach the first arc-shaped clamping plate 1, it simultaneously drives the bevel block 52 to squeeze the rectangular collection box 3 downward, causing the rectangular collection box 3 to tilt, discharging the water in the rectangular collection box 3. Then drive the cylindrical bar 5 to slide in the rectangular frame 51 to the side close to the first arc-shaped clamping plate 1 until it slides to one side of the third arc-shaped clamping plate 43, thereby driving the third arc-shaped clamping plate 43 to slide to the side close to the rectangular frame 51, and the fabric can be pulled to between the first arc-shaped clamping plates 1 again.
