Description

Technical Field

[0001] This invention relates to the field of canopy material processing and testing technology, and in particular to a tensile strength testing device and method based on canopy material processing. Background Technology

[0002] As a commonly used flexible composite material for outdoor covering and transportation protection, canopy materials often bear multi-directional external forces such as lateral tension, central support compression, bending and turning during use. Their tensile properties directly determine their service life and safety.

[0003] Currently available tensile testing equipment for canopy materials has limited functionality, mostly only capable of static tensile testing in a single direction. It cannot simulate the combined stress states of top support, lateral tension, and turning under actual working conditions. In addition, conventional testing equipment has poor sample clamping stability, which easily leads to material slippage and loosening of the clamps, resulting in large errors in the test data. Furthermore, the testing processes of traditional testing equipment are independent of each other, requiring step-by-step sample clamping and multiple tooling changes. The testing process is cumbersome and inefficient, and it cannot achieve multi-dimensional synchronous testing or perform independent turning tensile testing. It is difficult to meet the actual production needs of high-precision, high-efficiency, multi-directional tensile testing of canopy materials in mass production. Summary of the Invention

[0018] A tensile strength testing method based on canopy material processing, applicable to the tensile strength testing equipment based on canopy material processing described above, comprises the following steps:

[0019] Step 1: Material Placement and Positioning

[0020] Place the canopy material to be tested flat on the placement platform on top of the base, so that both ends of the canopy material are positioned above the lower clamping seats of the clamping and fixing mechanisms on both sides. Adjust the material's posture to ensure that it is laid flat without wrinkles and is centered and aligned.

[0021] Step 2: Clamping and fixing mechanism:

[0022] The first motor is started, which drives the first pulley to rotate. At the same time, the first belt drives the second pulley and the first bidirectional threaded rod to rotate. The first bidirectional threaded rod drives the first moving plate to move towards each other along the first guide rod, which drives the driven rod, gear column and rack plate to mesh and transmit power. The first traction arm drives the upper clamping seat to press down, so that the clamping block is inserted into the clamping groove. The upper clamping seat and the lower clamping seat are used to clamp and tighten, thus fixing the two ends of the canopy material.

[0023] Step 3: Simultaneous testing of the top support mechanism and the lateral tension testing mechanism:

[0024] The second motor is started, which drives the worm gear to rotate via the third pulley, the second belt, and the fourth pulley.

[0025] 1) Top support mechanism: The worm gear meshes with the worm wheel, which drives the threaded rod to rotate, thereby driving the driven plate and connecting rod to lift up, so that the top support block is pushed out of the storage slot of the placement platform, and the tensile strength of the top support is tested in the middle of the canopy material;

[0026] 2) Lateral tensile testing mechanism: The worm gear drives the second bevel gear to mesh with the first bevel gear, drives the second bidirectional threaded rod to rotate, and drives the second moving plate to move laterally along the second guide rod to perform lateral tensile testing on the canopy material;

[0027] The top support mechanism and the lateral tension detection mechanism operate synchronously to perform synchronous detection of lateral tension and top support tension.

[0028] Step 4: Tilting and Pulling Test by the Tilting and Pulling Mechanism

[0029] The third motor is started, and the drive gear meshes with the driven gear, driving the transmission rod, the sixth pulley, the third belt and the fifth pulley to drive the second extension rod and the threaded sleeve to rotate. This causes the third moving plate, the first swing arm, the first extension rod, the limit spring, the second swing arm and the third swing arm to slide in the sliding groove in coordination with the limit rod. This drives the auxiliary rod and the second traction arm to rotate and swing, causing the clamping and fixing mechanism to swing as a whole, thus completing the flipping and pulling test of the canopy material.

[0030] The two working modes can be run separately:

[0031] ① Start simultaneously with the second motor to achieve synchronous detection of top support, lateral pulling, and flipping pulling;

[0032] ② Turn off the second motor and start the third motor separately to perform an independent flipping and pulling test; after the test is completed, turn off all motors, reset the mechanism, loosen the clamping structure and remove the sample to complete the test.

[0033] Compared with existing technologies, the beneficial effects of this invention are:

[0034] 1. This invention integrates four functional mechanisms: clamping and fixing, central support, lateral pulling, and flipping pulling. Through the linkage design of worm gear and bevel gear transmission, it can realize simultaneous detection of top support tensile strength and lateral tensile strength, and can also activate the flipping pulling mechanism separately for independent detection. It can accurately simulate the complex stress conditions of canopy materials under actual use, such as top support compression, lateral pulling, bending and flipping. It breaks through the limitation of traditional equipment's single tensile test, and the detection dimensions are more comprehensive, which fits the actual application stress scenario and greatly improves the reference value of the test results.

[0035] 2. This invention features a dedicated clamping and fixing mechanism. Through the meshing transmission of a first motor, a bidirectional threaded rod, and a gear rack, the upper clamping seat and the lower clamping seat are precisely pressed together. The clamping block and the clamping groove are matched and limited, which can achieve full-coverage clamping and fixing of both ends of the canopy material. With the help of the guide rod for limiting and guiding, it avoids slippage, loosening, and wrinkling during material testing, ensures that the sample is clamped in a centered and flat position, eliminates the deviation of test data caused by unstable clamping, and effectively improves the accuracy and repeatability of tensile strength testing.

[0036] 3. This invention adopts a mechanical linkage structure such as belt drive, worm gear, and bevel gear meshing. The second motor can synchronously drive the top support mechanism and the lateral tensile testing mechanism, and the third motor independently controls the operation of the flipping and tensile mechanism. There is no need for manual step-by-step adjustment of tooling and sample position. The entire process of clamping, multi-directional tensile testing, and mechanism reset is completed automatically, reducing manual intervention and human operation errors, simplifying the testing process, greatly reducing the intensity of manual labor, and adapting to the rapid testing needs of batch production lines for canopy materials.

[0037] In summary, this equipment overcomes the shortcomings of traditional tensile strength testing equipment for canopy materials, which has limited functionality. It integrates multi-dimensional composite testing functions, can simulate multi-directional stress testing under actual working conditions, has a stable and reliable clamping structure to effectively ensure testing accuracy, and features a high degree of automation in mechanical linkage, simplifying the process and improving testing efficiency. The overall structure is reasonably laid out, operates smoothly, supports dual working modes, and adapts to different testing needs, providing a high-precision, high-efficiency, and multi-functional tensile strength testing solution for canopy material processing.

[0053] In this invention, the clamping and fixing mechanism 3 includes lower clamping seats 301 located on both sides of the placement platform 2. First fixing plates 302 are symmetrically fixedly connected to the bottom of the lower clamping seats 301. A first bidirectional threaded rod 303 is rotatably connected between the two first fixing plates 302. A first moving plate 304 is threadedly connected to both ends of the first bidirectional threaded rod 303. A driven rod 305 is rotatably connected to the first moving plate 304. A first traction arm 306 is fixedly connected to both ends of the driven rod 305. The same upper clamping seat 307 is rotatably connected between the two first traction arms 306.

One side of the gear column 308 meshes with the rack plate 309 for transmission. A second fixing plate 316 is symmetrically fixedly connected to the bottom of the lower clamping seat 301. A first guide rod 315 is fixedly connected between the second fixing plate 316 and the first fixing plate 302. The first movable plate 304 has a first threaded hole and a first guide hole respectively. The first bidirectional threaded rod 303 is threaded inside the first threaded hole, and the first guide rod 315 is movably sleeved inside the first guide hole.

The first bidirectional threaded rod 303 is fixedly connected to the second pulley 311. The second pulley 311 and the first pulley 317 are externally connected by a first belt 312. The first motor 310 starts to drive the first guide rod 303. The rotation of the pulley 317 simultaneously drives the rotation of the second pulley 311 via the first belt 312, which in turn drives the rotation of the first bidirectional threaded rod 303. This causes the two first moving plates 304 to move in opposite directions, and the first traction arm 306 to move laterally. During this movement, the gear column 308 and the rack plate 309 mesh and transmit power, causing the first traction arm 306 to slowly rotate while moving. This allows the upper clamping seat 307 to move up and down, thereby achieving the clamping and fixing operation of the awning material to be tested.

[0054] In this invention, the top support mechanism 4 includes a threaded rod 401 rotatably connected to the bottom of the placement platform 2.

The second motor 407 starts and drives the third pulley 408 to rotate, and at the same time drives the fourth pulley 409 to rotate through the second belt 410. The rotation of the fourth pulley 409 drives the worm gear 405 to rotate, meshing with the worm wheel 406, thereby driving the threaded rod 401 to rotate. The rotation of the threaded rod 401 drives the driven plate 402 and the connecting rod 403 to move, and at the same time drives the top support block 404 to move, so as to realize the top support and tension test of the canopy material to be tested.

[0055] In this invention, the transverse tensile testing mechanism 5 includes a second bidirectional threaded rod 501 rotatably connected to the inside of the placement platform 2.

One side of the second bevel gear 505 meshes with the first bevel gear 504 for transmission. When the worm gear 405 rotates, it drives the second bevel gear 505 to rotate and mesh with the first bevel gear 504 for transmission, thereby driving the rotation of the second bidirectional threaded rod 501. The rotation of the second bidirectional threaded rod 501 drives the second moving plate 502 to move in the opposite direction. Through the second traction arm 602, the clamping and fixing mechanism 3 is driven to move to both sides, thereby realizing the tensile testing treatment of the awning material to be tested by lateral tension.

[0056] In this invention, the flipping and pulling detection mechanism 6 includes an auxiliary rod 601 rotatably connected to the second moving plate 502. A second traction arm 602 is fixedly connected to both ends of the auxiliary rod 601. The top of the second traction arm 602 is fixedly connected to the bottom of the lower clamping seat 301.

Inside the limiting slide 614, the other end of the second extension rod 615 is fixedly connected to the fifth pulley 616. The top of the base 1 is fixedly connected to the third motor 620.

When the third motor 620 starts, it drives the drive gear 621 to rotate, and the driven gear... Wheel 622 engages in a meshing transmission, synchronously driving the rotation of transmission rod 617. The rotation of transmission rod 617 drives the rotation of sixth pulley 618, which in turn drives the rotation of fifth pulley 616 and second extension rod 615 via third belt 619. The rotation of second extension rod 615, through the engagement of limit slider and limit groove 614, drives the synchronous rotation of threaded sleeve 604. The rotation of threaded sleeve 604 drives the movement of third moving plate 605, which in turn drives the movement of first swing arm 606. The movement of first swing arm 606, through first extension rod 607, drives the synchronous movement of second swing arm 609. Since second swing arm 609 is hinged to third swing arm 611, the movement of first swing arm 606 and second swing arm 609 is synchronized.The third swing arm 611 is driven to rotate and swing, which in turn drives the second traction arm 602 to rotate via the limit rod 612, thereby realizing the flipping and tensile testing of the canopy material to be tested;

[0057] It is worth mentioning that the threads at both ends of the bidirectional threaded rod are opposite, which allows the moving plate to move in opposite directions.

[0058] Example 2

[0059] A tensile strength testing method based on canopy material processing, comprising the following steps:

[0060] Step 1: Material Placement and Positioning

[0061] Place the canopy material to be tested flat on the placement platform 2 on the top of the base 1, so that the two ends of the canopy material are positioned above the lower clamping seats 301 of the clamping and fixing mechanisms 3 on both sides. Adjust the posture of the material to ensure that it is laid flat without wrinkles and is centered and aligned.

[0062] Step 2: Clamping and fixing mechanism 3 clamps and fixes the device.

[0063] The first motor 310 is started, which drives the first pulley 317 to rotate. At the same time, the first belt 312 drives the second pulley 311 and the first bidirectional threaded rod 303 to rotate. The first bidirectional threaded rod 303 drives the first moving plate 304 to move towards each other along the first guide rod 315, which drives the driven rod 305, the gear column 308 and the rack plate 309 to mesh and transmit power. The first traction arm 306 drives the upper clamping seat 307 to press down, so that the clamping block 314 is inserted into the clamping groove 313. The upper clamping seat 307 and the lower clamping seat 301 are fitted and clamped together to complete the fixation of both ends of the canopy material.

[0064] Step 3: Simultaneous testing of the top support mechanism 4 and the lateral tension testing mechanism 5:

[0065] Start the second motor 407, which drives the worm gear 405 to rotate via the third pulley 408, the second belt 410 and the fourth pulley 409;

[0066] 1) Top support mechanism 4: The worm 405 meshes with the worm wheel 406, driving the threaded rod 401 to rotate, driving the driven plate 402 and the connecting rod 403 to lift, so that the top support block 404 is pushed out from the storage groove of the placement platform 2, and the top support tensile strength test is performed on the middle of the canopy material.

[0067] 2) Lateral tensile testing mechanism 5: The worm gear 405 drives the second bevel gear 505 to mesh with the first bevel gear 504, drives the second bidirectional threaded rod 501 to rotate, and drives the second moving plate 502 to move laterally along the second guide rod 503 to perform lateral tensile testing on the canopy material.

[0068] The top support mechanism 4 and the lateral tension detection mechanism 5 operate synchronously to perform synchronous detection of lateral tension and top support tension.

[0069] Step 4, Tear and Flip Testing Mechanism 6: Tear and Flip Testing

[0070] The third motor 620 is started, and the driven gear 621 meshes with the driven gear 622, driving the transmission rod 617, the sixth pulley 618, the third belt 619 and the fifth pulley 616 to drive the second extension rod 615 and the threaded sleeve 604 to rotate. This causes the third moving plate 605, the first swing arm 606, the first extension rod 607, the limit spring 610, the second swing arm 609 and the third swing arm 611 to slide in the sliding groove 613 in coordination with the limit rod 612. This drives the auxiliary rod 601 and the second traction arm 602 to rotate and swing, causing the clamping and fixing mechanism 3 to swing as a whole, thus completing the flipping and pulling test of the canopy material.

[0071] Two working modes are available:

[0072] ① Start simultaneously with the second motor 407 to achieve synchronous detection of top support, lateral pulling, and flipping pulling;

[0073] ②Turn off the second motor 407 and start the third motor 620 separately to perform an independent flipping and pulling test;

[0074] After the test is completed, all motors are turned off, the mechanism is reset, the clamping structure is released and the sample is removed to complete the test.

[0075] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
