Description

Technical Field

[0001] The present invention relates to the technical field of textile strength detection, in particular to a tensile strength detection device for textiles. Background Art

[0002] At present, textiles are products made by processing and weaving textile fibers. China is one of the earliest countries in the world to produce textiles. They are divided into two categories: woven fabrics and knitted fabrics. Industrial textiles have a wide range of uses and many varieties. Common ones include tarpaulins, gun jackets, filter cloths, and roadbed cloths. With the development of the times, the styles and shapes of textiles have greatly differed from traditional styles. Among them, strip-shaped textiles can be folded into different shapes and have a wider range of uses, which will increase production volume.

[0003] After production is completed, the strength of the cloth strips needs to be tested. During the testing process, the line rollers that failed the test cannot be marked according to the changes during the test. When processing is required later, it cannot be distinguished and manual processing is required, which increases the time for later processing and reduces the efficiency of later processing. In addition, multiple line rollers that need to be tested cannot be tested at the same time during the test. If multiple line rollers are tested, the space occupied by the test will also increase.

[0016] 1. During testing, the present invention activates the stretching mechanism and the clamping and fixing mechanism, and triggers the mobile trigger mechanism. When performing strength testing on a cloth strip, the ring-shaped installation allows for testing more cloth strips at a time without taking up too much space, thus increasing the applicability of the testing process. Furthermore, different triggering ends can be used during the testing process to classify the time points at which cloth strips break during testing. Furthermore, if a cloth strip does not break under a specified pressure, no external marking on the online roller is required to indicate that it is qualified. During the testing process, triggering is performed immediately upon breaking, thus avoiding delays in testing that could lead to erroneous judgments later.

[0017] 2. The present invention also uses liquid water of different colors to mark the textiles according to the strength they are suitable for during the tensile test through the abnormal marking mechanism. In the later processing, the textiles are directly classified according to the color difference, which increases the efficiency of the later classification and avoids the mixing of unqualified wire rollers and wire rollers of different strengths during the testing process. The classification and sorting need to be re-performed in the later stage, which not only increases the time for later processing but also increases the cost of post-processing. In the marking process, the stability of the marking end during work can be guaranteed to avoid the marking end being exposed to the outside for a long time, resulting in drying and inability to mark.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] See also Figure 1-8 The present invention provides a technical solution: a tensile strength testing device for textiles, comprising a fixed frame 1, a mounting circular frame 7 movably mounted in the inner cavity of the fixed frame 1, a plurality of fixed mounting rods 15 equidistantly mounted on the outer periphery of the mounting circular frame 7, a wire roller 11 mounted on the outer surface of the fixed mounting rods 15, and a woven cloth strip wound around the outer surface of the wire roller 11;

[0029] The stretching mechanism 2 includes a connecting rod 202, a mounting frame head 203 and a movable top block 205.

The movable frame head 305 is installed on the end of the connecting rod 202 away from the mounting frame head 203, and the mounting head 304 is provided on the end of the movable frame head 305 away from the connecting rod 202. The fixed clamping strip 301 is installed on the side of the mounting head 304 away from the movable frame head 305.

[0031] A connecting block is installed at the end of the fixed mounting rod 15 away from the mounting circular frame 7, and a mounting opening 14 is opened on both sides of the connecting block. A spring limit block 13 is installed inside the mounting opening 14. The side of the spring limit block 13 away from the mounting opening 14 is an arc-shaped structure. A movable cover plate 6 is installed on the top of the fixed frame 1 through a hinge, and a stable base frame 12 is installed on the bottom of the fixed frame 1;

[0032] The specific implementation method is: when the line roller 11 is installed on the outside of the fixed installation rod 15, press the spring limit block 13 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. When installing different line rollers 11, open the movable cover 6, and then install different line rollers 11 on the outside of the installation circular frame 7 in turn.

[0033] An annular stable slide rail 9 is installed around the left side of the inner cavity of the fixed frame 1. An annular stable slide bar 8 is slidably installed inside the annular stable slide rail 9. The end of the annular stable slide bar 8 away from the annular stable slide rail 9 is connected to the left side of the installation circular frame 7.

A control panel is installed on the front side of the fixed frame 1;

[0034] The specific implementation is as follows: when the mounting circular frame 7 rotates, the annular stabilizing slide bar 8 is driven to slide inside the annular stabilizing slide rail 9. By cooperating with the annular stabilizing slide bar 8 and the annular stabilizing slide rail 9, the stability and flexibility of the mounting circular frame 7 during the rotation process are increased.

[0035] The stretching mechanism 2 also includes an electric telescopic rod 201, a pressure controller 204, a fixed spring 206 and a movable connecting block 207. The electric telescopic rod 201 is installed in the middle of the fixed frame 1. The fixed end of the right end of the electric telescopic rod 201 passes through the middle of the bearing, and a connecting hole is provided at the bottom end of the fixed end of the bearing. 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 connecting block 207. The movable connecting block 207 has a T-shaped structure. The right end of the movable connecting 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. The left end of the fixed spring 206 is connected to the left end of the movable connecting 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 push the installation frame head 203 to move, so that the installation frame head 203 slides outside the movable top block 205, squeezing the fixed spring 206. 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 in contact with the pressure controller 204 for squeezing. 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 the side away from the connecting rod 202 through a rebound hinge. The end of the movable lever 308 away from the movable frame head 305 is connected to the mounting head 304. The end of the movable lever 308 located in the inner cavity of the movable frame head 305 is installed with an extrusion push block 307. The right side of the movable lever 308 is installed with a push spring 306. The right end of the push spring 306 is connected to the movable frame head 304. The right side of the inner cavity of the frame head 305 is connected, and a trigger switch 309 is installed at the middle and lower end of the left side of the inner cavity of the movable frame head 305. The trigger switch 309 is electrically connected to the control panel. An elastic push rod 303 is installed on the right side of the installation head 304. An extrusion block 302 is installed on the end of the elastic push rod 303 away from the installation head 304. The top of the fixed clamp 301 is a trumpet-shaped structure. The fixed clamp 301 and the elastic push rod 303 are both made of spring steel. 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.

[0038] The specific implementation is as follows: when performing strength testing on different textiles, the line roller 11 wrapped with the textile strip is installed on the outside of the installation circular frame 7 in sequence, 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 when 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 close to 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 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, thereby starting 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 without taking up too much 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 the cloth strip does not break 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 break to avoid delays during testing and the situation where incorrect judgments are made later.

[0039] The device also includes a mobile trigger mechanism 5, which includes a movable cylinder 501, a pull rope 502, a second touch switch 503, a first touch switch 504, a moving block 505 and a mounting spring 506.

The first touch switch 504 and the second touch switch 503 are electrically connected to the control panel;

[0040] The specific implementation is as follows: when the movable connecting block 207 moves, the pulling rope 502 is driven to move, and the moving block 505 is driven to move upward by the pulling rope 502, and the installation spring 506 is stretched. Later, the moving block 505 is driven to reset by the stretched installation spring 506.

The double-headed electric push rod 401 is electrically connected to the control panel. The top and bottom ends of the double-headed electric push rod 401 are both equipped with movable top plates 402, and the movable top plate 402 is away from the double-headed electric push rod. An extrusion airbag 403 is installed on one side of the movable push rod 401, and a fixed plate 404 is installed on the side of the extrusion airbag 403 away from the movable 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 movable top plate 402. Moving slide rails are installed around the left side of the inner cavity of the fixed frame 1 at positions relative to the moving slider, and the moving slider is slidably connected to the inside of the moving slide rail. An air hole is opened in the middle of the inner cavity of the fixed plate 404, and a connecting air pipe 405 is installed on the right side of the fixed plate 404 at a position relative to the air hole. 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 provided at the upper and lower ends of the inner cavity of the movable rod 410. Round holes are provided 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 circular frame 7, and blue liquid is added to the storage slot 409 on the side away from the installation circular frame 7. 10. A porous connecting plate 411 is installed at the top and bottom of the movable rod 410 through a small solenoid valve.

The identification block 408 is made of cotton material, and the small solenoid valve is electrically connected to the control panel.

[0043] The specific implementation 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 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 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 power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction is turned on. When the circuit of the telescopic end on the other side breaks during the stretching test, the trigger switch 309 is activated to activate the double-headed electric push rod 401 through the control panel, so that the telescopic end in the corresponding direction extends and drives the movable top plate 402 at the corresponding position to move. The movable top plate 402 squeezes the extrusion airbag 403 at the corresponding position and drives the arc-shaped push rod 407 to move. When the extrusion airbag 403 is squeezed, the air inside the extrusion 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 into the inside of the identification block 408. When the arc-shaped push 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 activated, 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 of the textiles during testing. In subsequent processing, they are directly classified by color, which increases the efficiency of subsequent classification and avoids unqualified line rollers 11 and line rollers 11 of different strengths being mixed together during the testing process, which requires re-classification and sorting later, which not only increases the time and cost of post-processing. In addition, during the marking process, the stability of the marking end during operation is ensured to avoid the marking end being exposed to the outside for a long time, resulting in drying and inability to mark.

[0044] Working principle: When the present invention is testing the strength of different textiles, the line roller 11 with the textile strips is installed on the outside of the installation circular frame 7 in sequence, 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 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, and 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, driving the installation head 304 and the fixed clamping strip 301 to move. The movable lever 308 moves to the right with the hinge as the axis, and the push spring 306 is squeezed during the movement. During the strength test of the fabric strip, if the fabric strip suddenly breaks, the fixed clamping strip 301 and the movable lever 308 lose their restraint force. The compressed push spring 306 pushes the movable lever 308 to the opposite side, driving the squeezing top block 307 to move and contact the trigger switch 309, activating the double-headed electric push rod 401 in 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 push the installation frame head 203 to move, so that the installation frame head 203 slides outside the movable top block 205, squeezing the fixed spring 206. Later, the fixed spring 206 after squeezing drives the installation frame head 203 to reset. When the installation frame head 203 slides outside the movable top block 205, the right end of the movable top block 205 contacts and squeezes 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, the small electromagnetic valve close to the side of the mounting frame 7 will be triggered, and the power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction will be turned on. When it moves to the second touch switch 503, the small electromagnetic valve away from the side of the mounting frame 7 will be triggered, and the other small electromagnetic valve will be closed, and the power supply of the telescopic end of the double-headed electric push rod 401 in the corresponding direction will be turned on, and the circuit of the telescopic end on the other side will be closed. When a break occurs during the stretching test, the trigger switch 309 will 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 driven to move, and the movable top plate 402 is moved to the opposite side. The extrusion airbag 403 at the corresponding position is squeezed, and the arc-shaped push rod 407 is driven to move. When the extrusion airbag 403 is squeezed, 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 squeezed with 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.
