[0031] A connecting block is installed at one end of the fixed mounting rod 15 away from the mounting circular frame 7, and mounting openings 14 are opened on both sides of the connecting block.

[0032] The specific implementation is as follows: when the line roller 11 is installed on the outside of the fixed installation rod 15, the spring limit block 13 is pressed to move toward the inner cavity of the installation port 14. When the line roller 11 is fitted onto the outside of the fixed installation rod 15, the spring limit block 13 loses its restraining force and moves to the inside of the installation port 14 to limit and fix the line roller 11.

The electric telescopic rod 201 is electrically connected to the control panel. The right end of the electric telescopic rod 201 is installed with a movable connection block 207. The movable connection block 207 is a T-shaped structure. The right end of the movable connection block 207 is connected to the left side of the movable top block 205. A pressure controller 204 is installed on the right side of the inner cavity of the mounting frame head 203. The pressure controller 204 is electrically connected to the control panel. Several pressure thresholds are set inside the pressure controller 204, and different thresholds correspond to different small solenoid valves. Several fixed springs 206 are installed around the left side of the mounting frame head 203, and the left end of the fixed spring 206 is connected to the left end of the movable connection block 207.

[0036] The specific implementation method is as follows: when performing strength testing, the electric telescopic rod 201 is started to drive the movable connecting block 207 to move, and the installation frame head 203 is pushed to move, so that the installation frame head 203 slides outside the movable top block 205, and the fixed spring 206 is squeezed. Later, the installation frame head 203 is driven to reset by the squeezed fixed spring 206. When the installation frame head 203 slides outside the movable top block 205, the right end of the movable top block 205 is contacted and squeezed with the pressure controller 204. When the expected pressure value is reached, the movement stops, and the strength test is stopped.

[0037] The clamping and fixing mechanism 3 also includes an extrusion block 302, an elastic push rod 303, a push spring 306, an extrusion push block 307, a movable lever 308 and a trigger switch 309. The movable frame head 305 is installed with a movable lever 308 on one side away from the connecting rod 202 through a rebound hinge.

A movable opening is opened on the side of the movable frame head 305 away from the connecting rod 202, and the extrusion top block 307 is made of rubber material;

[0038] The specific implementation is as follows: when performing strength tests on different textiles, the wire roller 11 wound with the textile strips is sequentially installed on the outside of the installation circular frame 7, so that one end of the strip is stuck between the fixed clamping strips 301. When winding, the elasticity of the elastic top rod 303 can also be used to increase the tightness of the squeezing block 302 in contact with the outside of the strip. After the end of the strip is fixed, the electric telescopic rod 201 is started to drive the movable connecting block 207 and the installation frame head 203 to move. When the installation frame head 203 moves, it drives the connecting rod 202 to move. When the connecting rod 202 moves, it drives the movable frame head 305 to move, and drives the installation head 304 and the fixed clamping strip 301 to move. With the hinge as the axis, the movable lever 308 is moved to the right side near the end of the connecting rod 202, and the push spring 306 is squeezed during the movement. During the strength test, when the cloth strip suddenly breaks, the fixed clamp strip 301 and the movable lever 308 lose their restraint force, and the movable lever 308 is pushed to the opposite side by the compressed push spring 306, and the extrusion top block 307 is driven to move and contact the trigger switch 309, so as to start the double-headed electric push rod 401 at the corresponding position. When the cloth strip is tested for strength, more cloth strips can be tested at one time by installing them in a ring-shaped distribution, and it will not take up more space, thereby increasing the applicability of the testing process. In addition, during the testing process, different trigger ends can be used to classify the time points when the cloth strip breaks during testing, and if there is no broken cloth strip under the specified pressure, there is no need for the external mark of the online roller 11 to indicate that it is qualified. During the testing process, the trigger processing is performed at the first time of the breakage to avoid delays during testing and the situation that incorrect judgment is made later.

Later, the moving block 505 is reset by the stretched installation spring 506.

An extrusion airbag 403 is installed on one side of the moving push rod 401, and a fixed plate 404 is installed on the side of the extrusion airbag 403 away from the moving top plate 402. The left side of the fixed plate 404 is connected to the left side of the inner cavity of the fixed frame 1, and a moving slider is installed on the left side of the moving top plate 402.

An air intake check valve is installed on the side of the fixed plate 404 away from the extrusion airbag 403;

[0042] A movable rod 410 is installed on the right side of the double-headed electric push rod 401 through a hinge. Storage slots 409 are opened at the upper and lower ends of the inner cavity of the movable rod 410. Round holes are opened on the left side of the opposite ends of the top and bottom storage slots 409. The end of the connecting air pipe 405 away from the fixed plate 404 is connected to the position of the round hole on the left side of the movable rod 410 through a gas transmission one-way valve. Red liquid is added to the storage slot 409 on the side close to the installation round frame 7, and blue liquid is added to the storage slot 409 on the side away from the installation round frame 7. The movable rod 4 10A porous connecting plate 411 is installed at the top and bottom through a small electromagnetic valve, an identification block 408 is installed at the right end of the porous connecting plate 411, the cross section of the identification block 408 is a triangular structure, a plurality of air holes are opened inside the porous connecting plate 411, a connecting port is opened at the top and bottom of the movable rod 410, a push plate 406 is installed at the top and bottom of the left side of the movable rod 410, an arc-shaped top rod 407 is installed on the right side of the movable top plate 402, the identification block 408 is made of cotton material, and the small electromagnetic valve is electrically connected to the control panel;

[0043] The specific implementation method is as follows: when the strength of the textile is tested, the moving block 505 is driven to slide inside the movable cylinder 501. When it moves to the first touch switch 504, the small electromagnetic valve close to the side of the mounting circular frame 7 is triggered, and the power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction is turned on. When it moves to the second touch switch 503, the small electromagnetic valve away from the side of the mounting circular frame 7 is triggered, and the other small electromagnetic valve is closed, and the power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction is turned on, and the telescopic end of the double-headed electric push rod 401 is closed. When the circuit of the telescopic end on the other side breaks during the stretching test, the trigger switch 309 is started to start the double-headed electric push rod 401 through the control panel, so that the telescopic end in the corresponding direction is extended, and the movable top plate 402 at the corresponding position is moved, and the movable top plate 402 squeezes the squeezing airbag 403 at the corresponding position, and drives the arc-shaped push rod 407 to move. When squeezing the squeezing airbag 403, the air inside the squeezing airbag 403 is transported to the corresponding storage slot 409 through the connecting air pipe 405. The air pressure inside the storage slot 409 is increased, and the liquid inside the storage slot 409 is transported to the inside of the porous connecting plate 411, so that the liquid flows to the inside of the identification block 408. When the arc-shaped top rod 407 moves, it contacts and squeezes the push plate 406, and drives the movable rod 410 and the identification block 408 to contact the outer end of the line roller 11 with the rebound hinge as the axis. When the second touch switch 503 is started, the above steps are reversed to mark the other end of the line roller 11. In the process of tensile testing of textiles, different colors of liquid water are used for marking according to the strength adapted to the textile testing. In the later processing, they are directly classified according to the color difference, which increases the efficiency of the later classification, avoids the mixing of unqualified line rollers 11 and line rollers 11 of different strengths during the testing process, and needs to be reclassified and sorted later, which not only increases the time of the later processing, but also increases the cost of the post-processing. In the marking process, the stability of the marking end during work can be guaranteed to avoid the long-term exposure of the marking end to the outside, resulting in the situation that the marking end is dry and cannot be marked.

[0044] Working principle: When the present invention performs strength testing on different textiles, the wire roller 11 wound with the textile strip is sequentially installed on the outside of the installation circular frame 7, so that one end of the strip is clamped between the fixed clamp strips 301. When winding, the elasticity of the elastic top rod 303 can be used to increase the tightness of the squeeze block 302 when it contacts the outside of the strip. After the end of the strip is fixed, the electric telescopic rod 201 is started to drive the movable connecting block 207 and the installation frame head 203 to move. When the installation frame head 203 moves, it drives the connecting rod 202 to move. When the connecting rod 202 moves, it drives the movable connecting block 207 and the installation frame head 203 to move. The movable frame head 305 moves, and drives the installation head 304 and the fixed clamping strip 301 to move, and the movable lever 308 moves to the right side with the hinge as the axis, and squeezes the push spring 306 during the movement. When the cloth strip is tested for strength, the cloth strip suddenly breaks, causing the fixed clamping strip 301 and the movable lever 308 to lose their restraining force, and the compressed push spring 306 pushes the movable lever 308 to move to the opposite side, and drives the squeeze top block 307 to move and contact the trigger switch 309, thereby starting the double-headed electric push rod 401 at the corresponding position;

[0045] When performing strength testing, the electric telescopic rod 201 is started to drive the movable connecting block 207 to move, and the installation frame head 203 is pushed to move, so that the installation frame head 203 slides outside the movable top block 205, and the fixed spring 206 is squeezed. Later, the installation frame head 203 is driven to reset by the squeezed fixed spring 206. When the installation frame head 203 slides outside the movable top block 205, the right end of the movable top block 205 is contacted and squeezed with the pressure controller 204. When the expected pressure value is reached, the movement stops, and the strength test is stopped.

[0046] When it moves to the first touch switch 504, it will trigger the small solenoid valve close to the side of the mounting circular frame 7, and connect the power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction. When it moves to the second touch switch 503, it will trigger the small solenoid valve away from the side of the mounting circular frame 7, and close the other small solenoid valve, and connect the power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction, and close the circuit of the telescopic end on the other side. When a fracture occurs during the stretching test, the start trigger switch 309 starts the double-headed electric push rod 401 through the control panel, so that the telescopic end in the corresponding direction is extended, and the movable top plate 402 at the corresponding position is driven to move, and the movable top plate 402 is moved to the opposite side. The extrusion airbag 403 at the corresponding position is extruded, and the arc-shaped push rod 407 is driven to move. When the extrusion airbag 403 is extruded, the air inside the extrusion airbag 403 is transported to the corresponding storage slot 409 through the connecting air pipe 405, thereby increasing the air pressure inside the storage slot 409, and transporting the liquid inside the storage slot 409 to the porous connecting plate 411, so that the liquid flows to the inside of the identification block 408. When the arc-shaped push rod 407 moves, it is contacted and extruded by the push plate 406, and the movable rod 410 and the identification block 408 are driven to contact one end of the outside of the line roller 11 with the rebound hinge as the axis. When the second touch switch 503 is started, the above steps are reversed to mark the other end of the line roller 11.
