Extensive use of fabric for wall decoration, partitions and background processing can also form a good commercial space display style. In the production process of fabric, in order to understand the performance of the fabric, the tearing force of the fabric is usually tested.

[0003] The traditional method of detecting the tearing force of fabric mainly relies on manual operation. People fix the two ends of the fabric, then pull the two ends of the fabric outward, and then detect the degree of tearing. This takes a lot of time and effort, which will reduce work efficiency and cannot meet the needs of enterprises. At the same time, when the fabric strips are pressed and fixed, uneven force and loose compression are prone to occur.

[0031] A fixing component 4, which is fixedly mounted on the top of the workbench 1 and is located in the middle of the bottom of the gantry 3;

[0032] The limiting component 7 is connected to the outer side of the screw rod 6 by a thread. By setting the limiting component 7, during the tensile force application process, the gap between the screw rod 6 and the movable plate 8 is avoided, which may cause the movable plate 8 to shake and vibrate, thereby causing the fixed component 4 on the movable plate 8 to shake, so that the tensile force actually applied to the fabric sample fluctuates, thereby affecting the detection data of the fabric tearing force. The side of the limiting component 7 away from the screw rod 6 is fixedly connected to the movable plate 8. There are two fixed components 4, and one fixed component 4 is fixedly connected to the movable plate 8.

[0033] Among them, the fixing component 4 includes a support plate 41, the support plate 41 is fixedly connected to the workbench 1, the support plate 41 is fixedly connected to the inner wall of the gantry 3, the top of the support plate 41 is fixedly connected with a fixing seat 42, the top of the fixing seat 42 is fixedly connected with a fixing block 43, the fixing block 43 is set as a U-shaped block, the inner wall of the fixing block 43 is slidably connected with a fixing piece 44, and a limiting plate 46 is provided at one end of the fixing block 43 away from the fixing piece 44, and a triangular groove is provided on the outer side of the limiting plate 46, and the trouser-shaped sample is placed inside the fixing block 43, and the staff turns the knob 441 to make the limiting plate 46 and the positioning block 446 approach the sample in the middle, so that the sample is located inside the positioning block 446 and the triangular groove, and the triangular groove on the limiting plate 46 is adapted to the positioning block 446, so as to increase the contact area between the fixing component 4 and the sample, and can more evenly distribute the clamping force, so that the sample can be more stably fixed during the detection process, reduce the possibility of sliding and displacement, and ensure the smooth progress of the detection;

[0034] The fixing member 44 includes a knob 441, the end of which is fixedly connected with a round rod 442, which passes through the fixing block 43, and the round rod 442 and the fixing block 43 are threadedly connected. In the initial state, the magnetic properties of the magnetic rod 449 and the magnetic block 4410 are the same. Under the action of the mutual repulsion between the magnetic rod 449 and the magnetic block 4410, the circular plate 447 is located at the opening of the circular hole 448. The staff turns the knob 441 to make the round rod 442 rotate inside the fixing block 43, so that the round rod 442 drives the limiting plate 46 and the positioning block 446 to move toward the middle, so that the positioning block 446 contacts and squeezes the sample, and the positioning block 446 is driven by the force to move the U-shaped tube 445 in the direction away from the sample. At this time, the U-shaped tube 445 drives the circular plate 447 to move. Since the sample is between the limiting plate 46 and the positioning block 446, the positioning block 446 is pressed against the sample. Under the squeezing between the positioning blocks 446, it fits tightly against the circular hole, so that the circular plate 447 slides inside the circular hole 448, and negative pressure is generated inside the circular hole 448, which adsorbs the sample on the limiting plate 46. Through negative pressure adsorption, the surface of the sample can be subjected to a more uniform tensile force, reducing the detection error caused by local uneven force. At the same time, the physical damage to the sample by the adsorption is small, and the original structure and performance of the sample can be maintained to the greatest extent, ensuring the authenticity of the detection result. The end of the round rod 442 away from the knob 441 is rotatably connected to the support block 443, and the round rod 442 is extended to the inside of the support block 443.

[0035] The second embodiment is based on the first embodiment. Figures 4 to 6 As shown, the inner wall of the fixed block 43 is fixedly connected with a square plate 45, and the top of the square plate 45 is fixedly connected with a guide rod 412. There are two guide rods 412. After being fixed, the motor 5 drives the screw 6 to rotate, and the screw 6 drives the fixed component 4 on the movable plate 8 to move upward, and then the tearing force of the sample is tested. By setting the guide rod 412, it is ensured that the fixed component 4 moves along a predetermined straight line trajectory to avoid deviation, distortion or other irregular movement modes, prevent uneven force distribution due to movement deviation, reduce measurement errors caused by non-axial tension, and make the test results more truly reflect the tearing force of the cloth, thereby improving the accuracy and reliability of the test. At the same time, it can also provide stable support for the entire detection system and reduce the influence of vibration and shaking on the detection process. The two guide rods 412 are symmetrically arranged with the fixed seat 42 as the center.

[0036] A positioning plate 47 is fixedly connected to the middle of the top of the fixed block 43. The positioning plate 47 is vertically arranged with the fixed block 43. An annular groove 48 is provided on the outer side of the positioning plate 47. A sliding rod 49 is slidably connected to the inner wall of the annular groove 48. There are two sliding rods 49. One sliding rod 49 is fixedly connected to the limit plate 46, and the other sliding rod 49 is fixedly connected to the top of the support block 443. The sliding rod 49 is set as a T-shaped plate. The outer side of the sliding rod 49 is rotatably connected to a guide wheel 410. The guide wheel 410 is symmetrically arranged with the annular groove 48 as the center. The top of the sliding rod 49 is fixedly connected to the limit rod 411. The sample is placed in the middle of the fixed block 43, and then By turning the knob 441, the sample is fixed. The knob 441 drives the limit plate 46 and the positioning block 446 to move toward the middle through the round rod 442, thereby driving the slide bar 49 to move inside the annular groove 48. At this time, by setting the limit rods 411 up and down, the middle line of the sample cutting is located in the middle of the fixed block 43, so that the force on the cloth during the tearing process is more uniform and symmetrical, reducing the uneven force caused by the offset of the cutting line, thereby affecting the accuracy of the detection data. There are two limit rods 411, and the two limit rods 411 are respectively fixedly installed on the two fixed components 4, and the limit rods 411 are point-symmetrically arranged.

A magnetic block 4410 is fixedly connected to the middle of the bottom of the U-shaped tube 445, and a magnetic rod 449 is fixedly connected to the inner wall of the through hole 444 near the magnetic block 4410.

[0038] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the limiting assembly 7 includes a fixed sleeve 71, which is fixedly connected to the movable plate 8. The fixed sleeve 71 is set in a trapezoidal shape. The inner wall of the fixed sleeve 71 is slidably connected to the limiting cylinder 72. The limiting cylinder 72 and the fixed sleeve 71 are splined. The inner wall of the limiting cylinder 72 is fixedly connected to the fixing cylinder 73. After working for a long time, the screw 6 and the movable plate 8 are not tightly matched or there is a gap, so that during the application of tension, the gap at the matching position may cause the fixing assembly 4 to shake and vibrate, making the actual application difficult. The tension on the fabric sample fluctuates, which also causes uneven force on the sample, thereby affecting the uniform transmission and stability of the tension. The inner wall of the fixing cylinder 73 is provided with a threaded groove, and the fixing cylinder 73 is threadedly connected to the screw 6. The inner wall of the fixing sleeve 71 near the bottom of the fixing cylinder 73 is provided with a through groove 77, and the inner wall of the through groove 77 is fixedly connected with a spring 78. The end of the spring 78 away from the through groove 77 is connected to the fixing cylinder 73. The outer side of the fixing cylinder 73 is conical, and the through groove 77 is conical near the fixing cylinder 73. The fixing cylinder 73 and the through groove 77 are connected. 7, through the two conical surfaces to cooperate, under the same pressure, can reduce the volume, increase the scope of application, the bottom of the fixing sleeve 71 is provided with a gasket 74, the gasket 74 is C-shaped, the gasket 74 can be radially contracted, and the gasket 74 is an elastic structure, when there is a gap between the limit assembly 7 and the screw 6, the gasket 74 will provide an inward contraction force, through the extrusion fit between the protrusion 79 and the notch, so that the fixing ring 75 and the fixing sleeve 71 are pushed apart, thereby eliminating the axial gap of the nut, by setting the elastic structure gasket The gasket 74 and the buffer pad 76 can eliminate the radial clearance between the screw 6 and the limit assembly 7, straighten the axial linear motion, reduce or even eliminate the vibration or even noise of the limit assembly 7 during the linear motion. A slot is provided on the outer side of the bottom of the fixed sleeve 71, and the slot and the protrusion 79 are trapezoidal. The end of the gasket 74 away from the fixed sleeve 71 is fixedly connected to the fixing ring 75, and the side of the fixing ring 75 close to the slot is fixedly connected to the protrusion 79, and the end of the limit tube 72 close to the fixed sleeve 71 is fixedly connected to the buffer pad 76.

[0039] During use, the motor 5 is connected to an external power supply, and the motor 5 drives the screw 6 to rotate, so that the screw 6 drives the fixing component 4 at the bottom of the movable plate 8 to approach the fixing component 4 at the bottom, and a sample that meets the standard requirements is cut out from the cloth, and the trouser-shaped sample is placed inside the fixing block 43. The staff turns the knob 441 to make the limit plate 46 and the positioning block 446 approach the sample in the middle, so that the sample is located inside the positioning block 446 and the triangular groove. By adapting the triangular groove on the limit plate 46 to the positioning block 446, the contact area between the fixing component 4 and the sample is increased, and the clamping force can be distributed more evenly, so that the sample can be more stably fixed during the detection process, the possibility of sliding and displacement is reduced, and the smooth progress of the detection is ensured.

[0040] In the initial state, the magnetic properties of the magnetic rod 449 and the magnetic block 4410 are the same. Under the action of the mutual repulsion between the magnetic rod 449 and the magnetic block 4410, the circular plate 447 is located at the opening of the circular hole 448. The staff turns the knob 441 to make the circular rod 442 rotate inside the fixed block 43, so that the circular rod 442 drives the limiting plate 46 and the positioning block 446 to move toward the middle, so that the positioning block 446 contacts and squeezes the sample. The positioning block 446 is driven by the force to move the U-shaped tube 445 away from the sample. At this time, the U-shaped tube 445 drives the circular plate 447 to move. Since the sample is squeezed between the limiting plate 46 and the positioning block 446, it is tightly attached to the circular hole, so that the circular plate 447 slides inside the circular hole 448, and a negative pressure is generated inside the circular hole 448, which adsorbs the sample on the limiting plate 46. After fixing, the motor 5 drives the screw 6 to rotate, and the screw 6 drives the fixed component 4 on the movable plate 8 to move upward, thereby detecting the tearing force of the sample.
