Description

Technical Field

[0001] The present invention relates to the technical field of lining cloth detection, and more specifically, to a multi-dimensional mechanical property testing machine for lining cloth. Background Art

[0002] In modern industrial manufacturing, as an extremely important reinforcing material, lining cloth is widely used in multiple fields such as clothing, shoes, hats, furniture, and automotive interiors. For application scenarios that require a certain degree of hardness and durability (such as automotive interiors or heavy furniture), the strength of the lining cloth plays a crucial role in the safety and durability of the final product. In actual application scenarios, lining cloth often faces multi-directional strong pulling. Traditional detection methods usually perform unidirectional pulling tests by clamping both ends of the lining cloth. For example, a textile fabric tearing strength detection device with the Chinese patent publication number CN208420516U. In this detection device, when working, the top and bottom of the fabric are respectively fixed in the clamping grooves of the upper and lower clamps with fastening bolts. The upper clamp is connected to the fixed bracket at the bottom of the top plate, and the lower clamp is connected to the hydraulic rod at the top of the power box through a connecting piece and a tensile sensor. Then, an instruction is sent to the controller through the control button to make the hydraulic rod contract, driving the lower clamp to descend and pull the fabric. The tensile sensor transmits the detected tensile force to the controller in real time. When the fabric breaks and the tensile force disappears, the controller controls the motor to rotate forward to make the hydraulic rod return to the initial height. In current lining cloth mechanical property detection devices, if multi-directional pulling is to be simulated, the installation position of the lining cloth needs to be frequently changed. In addition, there are various types of lining cloth materials, and lining cloths of different materials show differences in thickness and strength. Some lining cloths are also subjected to local surface reinforcement treatment or coated to enhance their performance. Existing pulling tests are difficult to cope with such diverse lining cloth characteristics. For example, for thinner lining cloths, it is easy to cause damage during the test, making further detection impossible. For thicker lining cloths, due to insufficient test force, it is difficult to accurately evaluate their tear resistance strength, and reliable data support cannot be provided for product R & D and quality control. In view of this, there is an urgent need for a multi-dimensional mechanical property testing machine for lining cloth to solve the above problems. Summary of the Invention

The middle support mechanism includes a support platform assembly, and an adjustment assembly is installed inside the support platform assembly. When the support platform assembly is at the lowest end, it can assist in supporting the middle end of the cloth during the process of winding and conveying the cloth. When the cloth is undergoing a round of tests, the support platform assembly is lifted, passes through the inside of the hollow frame to pull and lift the middle end of the cloth. Combining with the clamping of the side ends of the cloth by the side clamping group and the cloth winding rollers, the support platform assembly can perform mechanical property tests on the cloth in multiple dimensions. After the cloth undergoes a round of tests, the adjustment assembly extends the support platform assembly, and can perform pressurized tests on the cloth again.

[0005] As a further improvement of this technical solution, the side clamping group includes a fixed plate, a clamping plate is fixedly installed on the top of the fixed plate, a clamping cavity is formed inside the clamping plate, and a plurality of clamping wheels are rotatably arranged at the top and bottom of the clamping cavity. The plurality of upper clamping wheels operate synchronously, and the plurality of lower clamping wheels operate synchronously.

[0006] As a further improvement of this technical solution, multiple groups of the side clamping groups are provided and are respectively installed on the surfaces of both ends of the hollow frame away from the cloth winding rollers, and can perform multiple clamping and fixing on both sides of the cloth.

[0007] As a further improvement of this technical solution, a plurality of clamping bars are fixedly installed on the surfaces of the plurality of clamping wheels, and the plurality of clamping bars are used to increase the clamping force on the cloth.

[0008] As a further improvement of this technical solution, the support platform assembly includes a first strip board and a second strip board. Folding rods are fixedly installed at the bottoms of the first strip board and the second strip board. The first strip board and the second strip board are arranged in parallel, and an adjustment cavity is formed between the first strip board and the second strip board.

[0009] As a further improvement of this technical solution, the middle support mechanism further includes a control cylinder fixedly installed in the middle of the middle cavity. The end of the piston rod of the control cylinder is fixedly installed with a support panel, and one ends of the two folding rods away from the first strip board and the second strip board are slidably supported on the top of the support panel.

[0010] As a further improvement of this technical solution, the adjustment assembly includes an electric rod arranged in the adjustment cavity. One end of the electric rod is fixedly connected to the side surface of the first strip board, the output end of the electric rod is connected to the side surface of the second strip board, and a telescopic rod is connected between the first strip board and the second strip board.

[0011] As a further improvement of the technical solution, cover plates are fixedly installed at the top ends of the first board and the second board close to the adjustment cavity, and the two cover plates are in a fitting state.

[0012] As a further improvement of the technical solution, rounded corners are provided on the surfaces of the first board and the second board, and the rounded corners can reduce the damage to the lining cloth caused by the stretching of the first board and the second board.

[0013] As a further improvement of the technical solution, bevel angles are provided at the ends of the two cover plates away from the first board and the second board.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this lining cloth multi-dimensional mechanical property testing machine, during the placement process of testing the mechanical properties of the lining cloth, there are two cloth winding rollers, namely the cloth feeding roller and the cloth winding roller. The cloth feeding roller is responsible for feeding the lining cloth, and the cloth winding roller is used for winding the lining cloth. During the test, the lining cloth at the middle ends of the cloth feeding roller and the cloth winding roller is detected. At the same time, with the help of the side clamping group clamped and fixed at the side end of the hollow frame, the lining cloth is stabilized from multiple directions. When the lining cloth is placed, the support platform assembly located in the middle of the hollow frame is at the lowest position, which can support the middle part of the lining cloth and effectively reduce the unevenness of the lining cloth during placement; After the lining cloth is placed and fixed, it enters the initial stage of the test. Driven by the control cylinder, the support platform assembly starts to lift and pass through the hollow frame. During this process, the support platform assembly will push and pull the lining cloth located on the surface of the hollow frame. Since the middle end of the lining cloth is pulled and lifted, and the surrounding is fixed by the cloth control mechanism, the lining cloth can be simultaneously pulled in multiple directions, such as front and back, left and right, up and down. In this way, multi-dimensional synchronous testing can be achieved without multiple placements and fixations of the lining cloth; The lining cloth that passes the first round of detection will then enter the final detection stage. Under the control of the adjustment component, the support platform assembly further expands, so as to apply a greater pressure to the lining cloth in the same space for pulling, increasing the detection intensity. During the step-by-step detection process, the lining cloth can gradually adapt to different degrees of pulling forces and be tested in a state of fully demonstrating its own mechanical properties. This not only improves the accuracy of the overall test results but also effectively reduces the possibility of damage to the lining cloth caused by excessive pulling force in the first time.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] Embodiment, please refer to Figures 1 - 2 As shown, the purpose of this embodiment is to provide a multi-dimensional mechanical property testing machine for lining cloth, including a workbench 1. The workbench 1 includes a hollow frame 11 and a support base 12. The support base 12 is fixedly installed at the bottom of the hollow frame 11. A middle cavity 13 is formed in the middle of the support base 12. The middle cavity 13 is located at the lower end of the middle of the hollow frame 11, and the middle cavity 13 is communicated with the middle of the hollow frame 11; A cloth control mechanism 2 for test clamping of the cloth to be tested is provided on the surface of the hollow frame 11. The cloth control mechanism 2 includes two cloth winding rollers 21, which are respectively located at the top of both ends of the hollow frame 11. A side clamping group 22 is clamped and arranged in the middle of the hollow frame 11, and the side clamping group 22 is used for clamping and fixing the side ends of the cloth. A middle support mechanism 3 is installed inside the middle cavity 13. The middle support mechanism 3 includes a support platform assembly 31, and an adjustment assembly 32 is installed inside the support platform assembly 31. When the support platform assembly 31 is at the lowest end, it can assist in supporting the middle end of the cloth during the winding and conveying process of the cloth. When the cloth undergoes a round of tests, the support platform assembly 31 is lifted, passes through the inside of the hollow frame 11 to pull and lift the middle end of the cloth. Combining the clamping of the side ends of the cloth by the side clamping group 22 and the cloth winding rollers 21, the support platform assembly 31 can perform mechanical property tests on the cloth in multiple dimensions. After the cloth undergoes a round of tests, the adjustment assembly 32 extends the support platform assembly 31, and can perform pressure tests on the cloth again.

[0019] For the cloth that needs to be subjected to mechanical property tests, its ends need to be clamped by the side clamping group 22 first. Now, the specific structure of the side clamping group 22 will be disclosed. The side clamping group 22 includes a fixed plate 221. A clamping plate 222 is fixedly installed on the top of the fixed plate 221. An inner clamping cavity 223 is formed inside the clamping plate 222. A plurality of clamping wheels 224 are rotatably arranged at the top and bottom of the clamping cavity 223. The plurality of upper clamping wheels 224 operate synchronously, and the plurality of lower clamping wheels 224 operate synchronously.

[0020] Refer to Figure 3 And in combination with Figure 4 And Figure 5 As shown, among the two cloth winding rollers 21, one is a cloth feeding roller and the other is a cloth receiving roller. Both the cloth feeding roller and the cloth receiving roller are driven by motors to operate (not shown in the figure). A fixed plate 221 is provided at the side end of the hollow frame 11, and a clamping plate 222 is fixedly installed on the top of the fixed plate 221 for clamping the side end of the cloth. A plurality of clamping wheels 224 are arranged at the upper and lower inner cavities of the clamping cavity 223. The ends of the plurality of clamping wheels 224 at the same end are all connected to gears, and these gears are connected to each other by chains. Driven by a micro motor, the plurality of gears at the same end can rotate synchronously, thereby realizing the synchronous rotation of the plurality of clamping wheels 224 at the same end (using existing technology, not elaborated here, not shown in the figure); when the cloth is being wound up, the upper clamping wheels 224 and the lower clamping wheels 224 will rotate in opposite directions. For example, when the upper clamping wheels 224 rotate clockwise forward, the lower clamping wheels 224 will rotate counterclockwise backward. This reverse rotation can ensure that the cloth clamped between the upper and lower clamping wheels 224 advances smoothly. In this way, after completing the test of a section of cloth, without disassembling the device, the cloth located in the middle of the hollow frame 11 can be replaced by combining the two cloth winding rollers 21 and the side clamping group 22, and the test of the next section of cloth can be directly carried out.

[0021] It is worth mentioning that the fixing plate 221 is movably installed at the end of the hollow frame 11 (such as fixed by bolts). In this way, if the width of the test lining cloth changes, the position of the fixing plate 221 can be adjusted to achieve precise clamping of the side end of the lining cloth, ensuring the stability of the lining cloth during the entire test process, and greatly improving the applicability of the device and the accuracy of the test.

[0022] There are multiple side clamping groups 22, which are respectively installed on the two end surfaces of the hollow frame 11 away from the cloth winding roller 21, and can clamp and fix both sides of the lining cloth at multiple positions.

[0023] Considering the clamping effect of the clamping wheels 224 on the end of the lining cloth, therefore, a plurality of clamping bars 225 are fixedly installed on the surfaces of the plurality of clamping wheels 224, and the plurality of clamping bars 225 are used to improve the clamping force on the lining cloth.

[0024] The improvement lies in: combined with Figure 9 It can be seen that there are multiple side clamping groups 22, which are respectively installed on the two end surfaces of the hollow frame 11 away from the cloth winding roller 21. In cooperation with the two cloth winding rollers 21, the test lining cloth can be clamped from multiple directions, greatly improving the clamping stability. And, as Figure 5 shown, on the surface of the clamping wheel 224, there are multiple clamping bars 225, and their materials are usually selected from rubber or silica gel with high friction, further enhancing the clamping effect on the lining cloth and reducing the situation that the lining cloth breaks free from the clamping wheel 224 during the test. The clamping bars 225 are made of rubber or silica gel with high friction and have a certain elasticity. The elastic material will deform when subjected to pressure, so as to fit more closely with the surface of the lining cloth, increase the contact area, and better stabilize the lining cloth.

[0025] Next, the specific structure of the support platform assembly 31 will be disclosed. The support platform assembly 31 includes a first strip 311 and a second strip 312. Folding rods 314 are fixedly installed at the bottoms of the first strip 311 and the second strip 312. The first strip 311 and the second strip 312 are arranged in parallel, and an adjustment cavity is formed between the first strip 311 and the second strip 312.

[0026] The middle support mechanism 3 further includes a control cylinder 33 fixedly installed in the middle of the middle cavity 13. The end of the piston rod of the control cylinder 33 is fixedly installed with a support panel 34. One ends of the two folding rods 314 away from the first strip 311 and the second strip 312 are slidably supported on the top of the support panel 34.

[0027] Combined with Figure 10As shown, the first plate 311 and the second plate 312 are arranged in parallel. At the bottom of both of them, folding rods 314 are fixedly installed, and the two folding rods 314 are symmetrically distributed. The bottoms of the two folding rods 314 are slidably connected to the top of the support panel 34 (installed by existing technology, not shown in the figure). Figure 6 , in the initial stage of placing the lining cloth, the first plate 311 and the second plate 312 can effectively share the own weight of the lining cloth, reduce the premature sagging in the middle of the lining cloth due to its own weight, and ensure that the lining cloth remains relatively flat at the initial stage of placement, providing a good foundation for subsequent tests. At the same time, the support of the lining cloth by the first plate 311 and the second plate 312 cooperates with the side clamping group 22, acting on the lining cloth from different directions together, further enhancing the clamping effect on the lining cloth, making the lining cloth more stable during the whole test process, reducing the occurrence of displacement or loosening, and thus improving the accuracy and reliability of the test results. From Figure 7 it can be seen that in the initial stage of the mechanical property detection of the lining cloth, the control cylinder 33 exerts force to drive the support panel 34 and the first plate 311 and the second plate 312 arranged in parallel to move up synchronously. As they rise, the first plate 311 and the second plate 312 can smoothly pass through the middle of the hollow frame 11, and then pull up the middle end of the lining cloth. At this time, the four sides of the lining cloth are firmly fixed by the cloth winding roller 21 and the side clamping group 22, while the middle end is pulled upward. From the mechanical principle, when an object is subjected to forces in multiple different directions, the internal stress distribution will change complexly. In this multi-dimensional pulling situation, each part of the lining cloth bears tensions in different directions, which can comprehensively simulate the stress scenarios that the lining cloth may face in actual use. In this way, through this detection method, the effect of multi-dimensional mechanical testing can be achieved, and the mechanical properties of the lining cloth in different stress directions, such as tensile strength, tear resistance, etc., can be evaluated. This is one round of testing. During the process of testing the fabric, the tester can initially judge by directly observing the texture changes on the surface of the lining cloth. For example, if obvious tear marks or excessive texture deformation appear on the surface of the lining cloth, it can directly reflect the performance of the lining cloth in the corresponding stress direction. On the other hand, a detector (not shown in the figure) can also be installed on the top of the workbench 1, and the lining cloth can be more precisely detected and analyzed by using existing technology. These detection methods can accurately evaluate the mechanical properties of the lining cloth in different stress directions, such as tensile strength, tear resistance, etc.

[0028] The adjusting assembly 32 includes an electric rod 321 arranged in the adjusting cavity. One end of the electric rod 321 is fixedly connected to the side surface of the first plate 311, and the output end of the electric rod 321 is connected to the side surface of the second plate 312. A telescopic rod 322 is connected between the first plate 311 and the second plate 312, and the telescopic rod 322 is used to connect and support the first plate 311 and the second plate 312.

[0029] Combined with Figure 8 As shown, when the interlining that has passed the first round of detection enters the second round of detection, the electric rod 321 is activated to apply a thrust to the second strip 312, expanding the distance between the first strip 311 and the second strip 312. It should be noted that in this process, there is no need to lift the first strip 311 and the second strip 312 again, and the secondary stretching test of the interlining can be realized within a limited space; The mechanical properties of the material are anisotropic and non - linear. Different tensile distributions will cause different degrees of deformation and slip of the fiber structure inside the interlining. Expanding the distance between the first strip 311 and the second strip 312 makes the interlining subject to a tensile distribution different from that in the first round of detection, so as to more comprehensively evaluate the stress conditions that the interlining may face in various actual use scenarios. Changing the stress boundary conditions of the interlining changes the stress - strain state inside the interlining. By detecting the mechanical response of the interlining under this change, the mechanical properties of the interlining can be understood more deeply, providing richer data support for the accurate control of product quality and performance optimization.

[0030] This two - step testing method with different tensile forces, from the perspective of protecting the interlining, avoids the interlining from being subjected to excessive pulling force at one time, greatly reduces the damage to the interlining, extends the testable cycle of the interlining, and reduces the detection cost; from the perspective of simulating the actual use environment, it can better simulate the different tensile force conditions that the interlining may be subjected to in real use scenarios. In daily life or industrial applications, the tensile force borne by the interlining is not constant. Through two rounds of tests with different tensile forces, it can be closer to the actual stress process, thus improving the accuracy of the test results.

[0031] Since it is necessary to ensure that the interlining remains in a stable state during each test link when detecting the mechanical properties of the interlining, cover plates 313 are fixedly installed at the top of the first strip 311 and the second strip 312 close to the adjustment cavity, and the two cover plates 313 are in a fitting state.

[0032] The improvement lies in: Refer to Figure 10 As shown, cover plates 313 are fixedly installed at the top of the first strip 311 and the second strip 312 close to the adjustment cavity, and the two cover plates 313 are in a fitting state. In this way, it can better support the middle part of the interlining, reduce the situation of the interlining sagging, ensure that the interlining is always in an ideal stress state during the whole detection process, and provide a strong guarantee for accurately evaluating the mechanical properties of the interlining.

[0033] During the detection of the mechanical properties of the interlining, the first plate 311 and the second plate 312 will perform operations such as pulling on the interlining. If their surfaces are right-angled, during the stretching process, the right-angled edges are likely to generate a large frictional force with the interlining, and may even catch the interlining fibers, thereby causing damage such as scratches and tears to the interlining. Therefore, rounded corners 4 are provided on the surfaces of the first plate 311 and the second plate 312. The rounded corners 4 can reduce the damage to the interlining caused by the stretching of the first plate 311 and the second plate 312.

[0034] Bevel angles 41 are provided at one ends of the two covering plates 313 away from the first plate 311 and the second plate 312.

[0035] The improvement lies in: Refer to Figure 8 And in combination with Figure 10 As shown, rounded corners 4 are provided on the surfaces of the first plate 311 and the second plate 312. The rounded corners 4 can effectively disperse stress and reduce the damage to the interlining caused by the stretching of the first plate 311 and the second plate 312. Similarly, when the interlining is stretched, if the end corners of the covering plate 313 are too sharp, it will also cause similar damage to the interlining. Therefore, bevel angles 41 are provided at one ends of the two covering plates 313 away from the first plate 311 and the second plate 312. The bevel angles 41 can make the contact between the covering plate 313 and the interlining smoother, reduce the damage caused by the sharp end corners to the interlining when the interlining is stretched, ensure that the interlining is not damaged unnecessarily during the entire detection process, and thus guarantee the authenticity and reliability of the detection results.

[0036] In summary, the working principle of this solution is as follows: First, the interlining to be detected is fixed at the end corners by two cloth winding rollers 21 and multiple side clamping groups 22. During the initial stage of placing the interlining, the first plate 311 and the second plate 312 can effectively share the weight of the interlining itself, reduce the premature sagging of the middle part of the interlining due to its own weight, ensure that the interlining remains relatively flat at the initial placement stage, and provide a good foundation for subsequent tests. At the same time, the support of the first plate 311 and the second plate 312 for the interlining cooperates with the side clamping groups 22 and acts on the interlining together from different directions, further enhancing the clamping effect on the interlining; In the initial stage of the mechanical property detection of the lining cloth, the air cylinder 33 is controlled to exert force, driving the support panel 34 and the first strip 311 and the second strip 312 arranged in parallel to move upward synchronously. As they rise, the first strip 311 and the second strip 312 can smoothly pass through the middle of the hollow frame 11, and then pull and lift the middle end of the lining cloth. At this time, the four sides of the lining cloth are firmly fixed by the cloth winding roller 21 and the side clamping group 22, while the middle end is pulled upward. From the mechanical principle, when an object is subjected to forces in multiple different directions, the internal stress distribution will change complexly. In this multi-dimensional pulling situation, each part of the lining cloth bears tensions in different directions, which can comprehensively simulate the stress scenarios that the lining cloth may face in actual use. Thus, through this detection method, the effect of multi-dimensional mechanical testing can be achieved, and the mechanical properties of the lining cloth in different stress directions can be evaluated. For the lining cloth that has passed the first round of detection, when entering the second round of detection, the electric rod 321 is started to apply a thrust to the second strip 312, so that the distance between the first strip 311 and the second strip 312 is enlarged. By enlarging the distance between the first strip 311 and the second strip 312, the lining cloth is subjected to a different tensile force distribution from that in the first round of detection, so as to more comprehensively evaluate the stress conditions that the lining cloth may face in various actual use scenarios. By detecting the mechanical response of the lining cloth under this change, the mechanical properties of the lining cloth can be understood more deeply, providing richer data support for the precise control of product quality and performance optimization; During the testing of the fabric, the tester can initially judge by directly observing the texture changes on the surface of the lining cloth. For example, if obvious tearing texture, excessive texture deformation, etc. appear on the surface of the lining cloth, they can intuitively reflect the performance of the lining cloth in the corresponding stress direction. On the other hand, a detector can also be installed on the top of the workbench 1 to conduct more precise detection and analysis of the lining cloth using existing technologies. These detection methods can accurately evaluate the mechanical properties of the lining cloth in different stress directions.
