Technical Field
[0001] This invention relates to the field of tensile strength testing technology, specifically to a tensile strength testing device for the production of plastic nets based on new materials. Background Technology
[0002] Existing clamping devices for testing the tensile strength of plastic mesh have shortcomings. Traditional clamps have large errors in adjusting the clamping force, lack reliable locking functions, and are prone to slippage when dealing with plastic meshes with large gaps or new materials. Furthermore, the poor adaptability of the clamping surfaces can lead to uneven stress distribution and deviations in the test data. To solve these problems, it is necessary to develop a dedicated clamping structure that is adaptable to new materials, provides stable clamping, and ensures uniform pressure, thereby improving the accuracy of the test.
[0003] Patent CN218726047U discloses a tensile strength testing device for plastic mesh production, including a support plate. Slide grooves are formed on both sides of the upper surface of the support plate, and movable plates are slidably connected within each groove. Two tension rods are welded to the opposing surfaces of each movable plate. One end of each tension rod passes through a limiting plate and is welded with a hanging ring. A clamping frame is installed on the movable plate via a connecting mechanism. The clamping frame is fixed to the clamping plate by four bolts. A plastic mesh is clamped between the clamping frame and the clamping plate. The plastic mesh is first fixedly installed on the clamping frame and the clamping plate. During use, the movable plates achieve a tensile effect. The device combines tensile strength testing with stable sliding during use, preventing the instability of tensile strength in existing technologies from affecting the testing effect of unstable tensile direction.
[0004] However, when using the above-mentioned device, it is difficult to simultaneously stretch the middle area of the plastic net upward during the fixed tensile test, resulting in uneven force applied to the plastic net and affecting the accuracy of the subsequent tensile test data of the plastic net. Therefore, a tensile testing device for plastic net production based on new materials is proposed to solve the above-mentioned problems. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a tensile strength testing device for the production of plastic nets based on new materials, which addresses the shortcomings of the prior art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a tensile strength testing device for the production of plastic mesh based on a new material, comprising a base, a support frame on the base, a reciprocating lead screw on the support frame, a motor on the top of the support frame, a fixing hook fixedly connected to the inner wall of the support frame, a movable block movably connected to the circumferential surface of the reciprocating lead screw, a fixing frame fixedly connected to the left side of the movable block, an electric telescopic rod fixedly connected to the front of the movable block, a roller block fixedly connected to the telescopic end of the electric telescopic rod, and a fixed frame fixedly connected to the inner wall of the fixing frame. A first elastic telescopic rod is connected, with a protrusion fixedly connected to the telescopic end of the first elastic telescopic rod.

A connecting rod is rotatably connected to the circumferential surface of the connecting plate. A glue groove block is provided on the fixed frame. A slider is slidably connected to the inner wall of the glue groove block. A hinge plate is rotatably connected to the inner wall of the slider through a torsion spring. This allows the first locking block to drive one end of the new material plastic mesh to move downward and perform tensile testing. It can apply a uniform tensile force to the new material plastic mesh and improve the testing efficiency of the device for the new material plastic mesh.
[0007] Preferably, the inner wall of the support frame is provided with an anti-detachment mechanism to prevent the plastic net from falling off, and the inner wall of the anti-detachment mechanism is provided with a clamping mechanism for clamping the plastic net.

The protrusion is located on the movement trajectory of the roller block, and the protrusion is used to drive the clamping block to move. The slider can stretch the middle area of the stretching end of the new material plastic net upward during the stretching process. It can move in the same direction as both ends of the stretching side of the new material plastic net, and can apply the tensile force evenly. This can further improve the tensile strength detection accuracy of the device and enhance the detection precision.
[0008] Preferably, the connecting rod is rotatably connected to the circumferential surface of the slider, and the connecting rod is used to drive the slider to rise. The movement of the connecting plate will drive the connecting rod to move. During the movement, the connecting rod will synchronously adjust its own angle.

[0009] Preferably, the anti-fall-off mechanism includes an electric telescopic rod II, which is fixedly connected to the inner wall of the support frame. A fixing plate is fixedly connected to the telescopic end of the electric telescopic rod II. An elastic telescopic rod II is fixedly connected to the inner wall of the support frame. A limiting arc plate is fixedly connected to the inner wall of the fixing plate, so that the limiting arc plate will seal the fixing hook, ensuring that the new material plastic mesh fixed on the fixing hook cannot fall off. This ensures the stability of the device in tensile testing of the new material plastic mesh and further improves the tensile testing accuracy of the device.
[0010] Preferably, the anti-detachment mechanism further includes an elastic telescopic rod three, which is fixedly connected to the inner wall of the fixed frame. An L-shaped rod is fixedly connected to the telescopic end of the elastic telescopic rod three.

An elastic telescopic rod four is fixedly connected to the inner wall of the L-shaped rod, and a smoothing plate is fixedly connected to the telescopic end of the elastic telescopic rod four. A vertical rod is installed on the base. This further improves the tensile strength testing accuracy of the device, prevents the new material plastic mesh from detaching during the testing process, and avoids affecting the subsequent tensile strength testing efficiency. Smoothing the surface of the new material plastic mesh ensures the accuracy of the tensile strength testing data, reduces testing errors caused by wrinkles in the new material plastic mesh, and significantly improves the testing efficiency of the device.
[0011] Preferably, the limiting arc plate contacts the fixing hook and is used to seal the fixing hook. The limiting arc plate is fixedly connected to the telescopic end of the elastic telescopic rod II. The vertical rod is located on the movement trajectory of the abutment block.

During the movement of the limiting arc plate, the limiting arc plate will stretch the elastic telescopic rod II. The elastic telescopic rod II can ensure the stable movement of the limiting arc plate.
[0012] Preferably, the clamping mechanism includes a rack, which is fixedly connected to the inner wall of the limiting arc plate. A reciprocating screw is rotatably connected to the inner wall of the support frame. A gear is fixedly connected to the circumferential surface of the reciprocating screw, and a transverse plate is movably connected to the circumferential surface of the reciprocating screw. A pressure plate is fixedly connected to the bottom of the transverse plate, so that the pressure plate can clamp the new material plastic mesh fixed on the fixing hook. This ensures the safety of the device in detecting the new material plastic mesh, can adapt to long-term tensile testing, and improves the accuracy of the test.
[0013] Preferably, the clamping mechanism further includes a second clamping block, which is fixedly connected to the front of the pressure plate. The inner wall of the second clamping block is fixedly connected to a limiting post. The second clamping block can be positioned at the larger opening of the new material plastic mesh and limit and fix the new material plastic mesh. At the same time, the limiting post can prevent the new material plastic mesh from slipping through the gaps in the parts. It can limit and fix each opening of the new material plastic mesh, ensuring that the applied tension is stable and uniform, and improving the detection efficiency of the device.
[0014] Preferably, the rack meshes with the gear, and the rack is used to drive the gear to rotate. During the downward movement of the limiting arc plate, the movement of the limiting arc plate will drive the rack to move. During the movement of the rack, the rack will drive the gear to rotate, and the rotation of the gear will drive the reciprocating lead screw to rotate.

This guarantees the stability of the device's tensile strength testing of the new material plastic mesh, further improving the tensile strength testing accuracy and preventing the new material plastic mesh from falling off during testing, which would affect subsequent tensile strength testing efficiency. Smoothing the surface of the new material plastic mesh ensures the accuracy of the tensile strength test data, reduces testing errors caused by wrinkles in the new material plastic mesh, and significantly improves the testing efficiency of the device.

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.
[0021] Please see Figures 1-11One embodiment of the present invention is as follows: a tensile strength testing device for the production of plastic mesh based on a new material, comprising a base 1, a support frame 2 mounted on the base 1, a reciprocating lead screw 3 mounted on the support frame 2, a motor mounted on the top of the support frame 2, a fixing hook 6 fixedly connected to the inner wall of the support frame 2, a movable block 7 movably connected to the circumferential surface of the reciprocating lead screw 3, a fixing frame 8 fixedly connected to the left side of the movable block 7, and an electric telescopic rod 9 fixedly connected to the front of the movable block 7, the electric telescopic rod 9 being telescopic... A roller block 10 is fixedly connected to the end of the fixed frame 8. An elastic telescopic rod 11 is fixedly connected to the inner wall of the fixed frame 8. A protrusion 12 is fixedly connected to the telescopic end of the elastic telescopic rod 11. A locking block 13 is fixedly connected to the rear of the protrusion 12. A connecting plate 14 is fixedly connected to the inner wall of the protrusion 12. A connecting rod 15 is rotatably connected to the circumferential surface of the connecting plate 14. A glue groove block 16 is provided on the fixed frame 8. A slider 17 is slidably connected to the inner wall of the glue groove block 16. A hinge plate 18 is rotatably connected to the inner wall of the slider 17 through a torsion spring. When the device is in use, the inspector needs to fix both ends of the new material plastic mesh to the fixing hooks 6 respectively. After the new material plastic mesh is fixed, it will hang down naturally and be located in the fixing area of the fixing frame 8. At this time, when the electric telescopic rod 9 is started, the telescopic end of the electric telescopic rod 9 will drive the roller block 10 to move. After the roller block 10 moves a certain distance, it will contact the arc surface of the protrusion 12 and squeeze and push the protrusion 12 to move. During the movement of the protrusion 12, the protrusion 12 will drive the locking block 13 to move. At the same time, the protrusion 12 will drive the connecting plate 14 to move synchronously. At this time, the locking block 13 will be located in the gap of the new material plastic mesh and drive a part of the new material plastic mesh to be located in the groove of the glue tank block 16. At the same time, when the motor is started, the output end of the motor will... The reciprocating screw 3 rotates, which in turn rotates the moving block 7, which in turn rotates the fixed frame 8. However, the fixed frame 8 is indirectly limited by the other reciprocating screw 3, so the moving block 7 can only move up and down through the reciprocating groove on the surface of the reciprocating screw 3 during the rotation of the reciprocating screw 3. The up and down movement of the moving block 7 causes the fixed frame 8 to move downward, which in turn causes the elastic telescopic rod 11 to move. The elastic telescopic rod 11 causes the protrusion 12 to move, which in turn causes the locking block 13 to move. At this time, the locking block 13 can move one end of the new material plastic mesh downward and perform tensile testing, which can apply a uniform tensile force to the new material plastic mesh and improve the testing efficiency of the device for the new material plastic mesh. The inner wall of the support frame 2 is provided with an anti-fall mechanism 4 for preventing the plastic net from falling off. The inner wall of the anti-fall mechanism 4 is provided with a clamping mechanism 5 for clamping the plastic net. The reciprocating screw 3 is fixedly connected to the output end of the motor. The protrusion 12 is located on the movement trajectory of the roller block 10, and the protrusion 12 is used to drive the locking block 13 to move. The connecting rod 15 is rotatably connected to the circumferential surface of the slider 17, and the connecting rod 15 is used to drive the slider 17 to rise. When the device is started, the movement of the connecting plate 14 will drive the connecting rod 15 to move. During the movement, the connecting rod 15 will adjust its own angle synchronously. During the angle adjustment, the connecting rod 15 will drive the slider 17 to move upward. The movement of the slider 17 will drive the hinge plate 18 to move. During the movement of the slider 17, the middle area of the stretching end of the new material plastic mesh can be stretched upward. It can move in the same direction as both ends of the stretching side of the new material plastic mesh, and can apply the tensile force evenly. This can further improve the tensile strength detection accuracy of the device and improve the detection precision. Overall working principle: The elastic telescopic rod 11 drives the protrusion 12 to move, and the protrusion 12 drives the locking block 13 to move. At this time, the locking block 13 can drive one end of the new material plastic mesh to move downward and perform tensile testing. It can apply a uniform tensile force to the new material plastic mesh, which can improve the testing efficiency of the device for the new material plastic mesh. It can stretch the middle area of the stretched end of the new material plastic mesh upward, and can move in the same direction as both ends of the stretched side of the new material plastic mesh, which can apply a uniform tensile force, further improving the tensile testing accuracy of the device and enhancing the testing precision.
[0022] Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the anti-fall mechanism 4 includes an electric telescopic rod 401, which is fixedly connected to the inner wall of the support frame 2. The telescopic end of the electric telescopic rod 401 is fixedly connected to a fixing plate 402. An elastic telescopic rod 403 is fixedly connected to the inner wall of the support frame 2. A limiting arc plate 404 is fixedly connected to the inner wall of the fixing plate 402. When the device is started, after the testing personnel have fixed the new material plastic mesh, the electric telescopic rod 401 will be activated. The telescopic end of the electric telescopic rod 401 will drive the fixed plate 402 to move synchronously. The movement of the fixed plate 402 will drive the limiting arc plate 404 to move. During the movement of the limiting arc plate 404, the limiting arc plate 404 will stretch the elastic telescopic rod 403. The elastic telescopic rod 403 can ensure the stability of the movement of the limiting arc plate 404. After the limiting arc plate 404 has moved a certain distance, the limiting arc plate 404 will seal the fixing hook 6, which can ensure that the new material plastic mesh fixed on the fixing hook 6 cannot fall off. This can ensure the stability of the device in the tensile test of the new material plastic mesh, further improve the tensile test accuracy of the device, and avoid the new material plastic mesh from falling off during the test, which would affect the efficiency of subsequent tensile tests. The anti-fall-off mechanism 4 also includes an elastic telescopic rod 3 405, which is fixedly connected to the inner wall of the fixed frame 8. The telescopic end of the elastic telescopic rod 3 405 is fixedly connected to an L rod 406. The circumferential surface of the L rod 406 is rotatably connected to a pull rod 407. The circumferential surface of the pull rod 407 is rotatably connected to a stop block 408. The inner wall of the L rod 406 is fixedly connected to an elastic telescopic rod 409. The telescopic end of the elastic telescopic rod 409 is fixedly connected to a squeegee 410. A vertical rod 411 is installed on the base 1. A limiting arc plate 404 contacts the fixed hook 6 and is used to seal the fixed hook 6. The limiting arc plate 404 is fixedly connected to the telescopic end of the elastic telescopic rod 2 403. The vertical rod 411 is located on the movement trajectory of the stop block 408. When the device is in use, the movement of the fixed frame 8 will cause the elastic telescopic rod 405 to move downwards. The movement of the elastic telescopic rod 405 will cause the pull rod 407 to move downwards. The movement of the pull rod 407 will cause the abutment block 408 to move. At the same time, the L rod 406 will cause the elastic telescopic rod 409 to move downwards. The movement of the elastic telescopic rod 409 will cause the smearing plate 410 to move downwards synchronously. After the abutment block 408 moves downwards a certain distance, the abutment block 408 will contact the vertical rod 411. At this time, the vertical rod 411 can push the abutment block 408 upwards by pressing it in the opposite direction. At this time, the distance between the abutment block 408 and the fixed frame 8 will gradually shorten. During the upward movement of 408, the stop block 408 will drive the pull rod 407 to rise. During the upward movement, the pull rod 407 will adjust its angle synchronously. The angle adjustment of the pull rod 407 will synchronously drive the L rod 406 to move laterally. The lateral movement of the L rod 406 will drive the elastic telescopic rod 409 to move. The movement of the elastic telescopic rod 409 will drive the smoothing plate 410 to move. The smoothing plate 410 can smooth the surface of the new material plastic mesh during the stretching process, which can ensure the accuracy of tensile test data, reduce the detection error caused by wrinkles in the new material plastic mesh, and significantly improve the detection efficiency of the device. The clamping mechanism 5 includes a rack 501, which is fixedly connected to the inner wall of the limiting arc plate 404. The inner wall of the support frame 2 is rotatably connected to a reciprocating screw 502. A gear 503 is fixedly connected to the circumferential surface of the reciprocating screw 502. A transverse plate 504 is movably connected to the circumferential surface of the reciprocating screw 502. A pressure plate 505 is fixedly connected to the bottom of the transverse plate 504. When the device is in use, as the limiting arc plate 404 moves downward, the movement of the limiting arc plate 404 will drive the rack 501 to move. During the movement of the rack 501, the rack 501 will drive the gear 503 to rotate. The rotation of the gear 503 will drive the reciprocating screw 502 to rotate. During the rotation of the reciprocating screw 502, the reciprocating screw 502 will drive the transverse plate 504 to rotate. However, at this time, the transverse plate 504 is limited by the area, so that during the rotation of the reciprocating screw 502, the transverse plate 504 can only move laterally through the reciprocating groove on the surface of the reciprocating screw 502. The movement of the transverse plate 504 will drive the pressure plate 505 to move. After moving a certain distance, the pressure plate 505 can clamp the new material plastic mesh fixed on the fixing hook 6, which can ensure the safety of the device in detecting the new material plastic mesh, adapt to long-term tensile testing, and improve the detection accuracy. The clamping mechanism 5 also includes a second clamping block 506, which is fixedly connected to the front of the pressure plate 505. A limit post 507 is fixedly connected to the inner wall of the second clamping block 506. The rack 501 meshes with the gear 503, and the rack 501 is used to drive the gear 503 to rotate. When the device is started, the pressure plate 505 moves, which in turn moves the second locking block 506. During the movement of the second locking block 506, the second locking block 506 also moves the limiting post 507. During the movement of the second locking block 506, the second locking block 506 can be positioned at the larger mesh opening of the new material plastic mesh and limit and fix the new material plastic mesh. At the same time, the limiting post 507 can prevent the new material plastic mesh from slipping through the gaps in the parts and can limit and fix each mesh opening of the new material plastic mesh, ensuring that the applied tension is stable and uniform, and improving the detection efficiency of the device. Overall working principle: This system ensures the stability of the tensile testing of new material plastic mesh, further improving the accuracy of the tensile testing and preventing the plastic mesh from falling off during the testing process, which would affect the efficiency of subsequent tensile testing. The movement of the elastic telescopic rod 409 moves the smoothing plate 410, which smooths the surface of the plastic mesh during the stretching process, ensuring the accuracy of the tensile test data, reducing testing errors caused by wrinkles in the plastic mesh, significantly improving the testing efficiency of the device, ensuring the safety of the device in testing the plastic mesh, and adapting to long-term tensile testing, thus improving the testing accuracy. At the same time, the limiting post 507 prevents the plastic mesh from slipping through the gaps in the parts, and limits and fixes each opening of the plastic mesh, ensuring that the applied tension is stable and uniform, thereby improving the testing efficiency of the device.
