Description

Technical Field

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

[0002] In modern industrial manufacturing, interlining is an extremely important reinforcing material and is widely used in a variety of fields, including clothing, shoes and hats, furniture, and automotive interiors. For applications that require a certain degree of hardness and durability (such as automotive interiors or heavy furniture), the strength of the interlining plays a key role in the safety and durability of the final product.

[0003] In actual application scenarios, interlinings are often subjected to strong pulling forces in multiple directions. Traditional testing methods usually perform unidirectional pulling tests by clamping the two ends of the interlining. For example, a textile fabric tearing strength testing device with Chinese patent publication number CN208420516U is described. During operation, the top and bottom of the fabric are first fixed to the clamping grooves of the upper and lower clamps with fastening bolts, respectively. 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 via a connector and a tension sensor. Then, a control button is used to send a command to the controller to retract the hydraulic rod, driving the lower clamp to descend and pull the fabric. The tension sensor transmits the detected tension to the controller in real time. When the fabric breaks and the tension disappears, the controller controls the motor to rotate forward to return the hydraulic rod to its initial height.

[0004] Current interlining mechanical property testing equipment requires frequent changes in the interlining's installation position to simulate multi-directional pulling. Furthermore, interlinings come in a wide variety of materials, varying in thickness and strength. Some interlinings undergo local surface reinforcement or coating to enhance performance. Existing pull tests are unable to cope with such diverse interlining properties. For example, thin interlinings can easily be damaged during testing, making further testing impossible. Furthermore, for thicker interlinings, insufficient testing intensity makes it difficult to accurately assess their tear resistance, hindering reliable data support for product development and quality control.

[0005] In view of this, there is an urgent need for a lining cloth multi-dimensional mechanical properties testing machine to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a lining cloth multi-dimensional mechanical properties testing machine to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides a multi-dimensional mechanical property testing machine for lining cloth, comprising a workbench, wherein the workbench comprises a hollow frame and a support base, wherein the support base is fixedly mounted on the bottom of the hollow frame, wherein a central cavity is formed in the middle of the support base, wherein the central cavity is located at the lower end of the central portion of the hollow frame, and the central cavity is communicated with the central portion of the hollow frame;

[0008] The surface of the hollow frame is provided with a cloth control mechanism for clamping the lining cloth to be tested, and the cloth control mechanism includes two cloth winding rollers, which are respectively located at the top of the two ends of the hollow frame. The middle part of the hollow frame is clamped with a side clamping group, which is used to clamp and fix the side ends of the lining cloth;

[0009] A middle support mechanism is installed inside the middle cavity, and the middle support mechanism includes a support platform assembly. An adjustment assembly is installed inside the support platform assembly. When the support platform assembly is located at the lowest end, it can provide auxiliary support for the middle end of the lining cloth during the winding and conveying process of the lining cloth;

[0010] When the lining cloth undergoes a round of testing, the support assembly is lifted and passes through the interior of the hollow frame to pull and lift the middle end of the lining cloth. Combined with the side clamping group and the cloth winding roller clamping the end of the lining cloth, the support assembly can perform mechanical property testing on the lining cloth in multiple dimensions. After the lining cloth undergoes a round of testing, the adjustment assembly expands the support assembly and can perform pressure testing on the lining cloth again.

[0011] As a further improvement of the present technical solution, the side clamp 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 multiple clamping wheels are rotatably provided on the top and bottom of the clamping cavity, the multiple clamping wheels at the upper end operate synchronously, and the multiple clamping wheels at the lower end operate synchronously.

[0012] As a further improvement of the present technical solution, the side clamping groups are provided in multiple groups, which are respectively installed on the two end surfaces of the hollow frame away from the cloth winding roller, and can clamp and fix the two sides of the lining cloth at multiple locations.

[0013] As a further improvement of the present technical solution, a plurality of gripping strips are fixedly mounted on the surfaces of the plurality of clamping wheels, and the plurality of gripping strips are used to enhance the clamping force on the lining cloth.

[0014] As a further improvement of the present technical solution, the support platform assembly includes a first strip and a second strip, and a folding rod is fixedly installed at the bottom of the first strip and the second strip. The first strip and the second strip are arranged in parallel, and an adjustment cavity is formed between the first strip and the second strip.

[0015] As a further improvement of the present technical solution, the middle branch mechanism also includes a control cylinder fixedly installed in the middle of the middle cavity, and a support panel is fixedly installed on the end of the piston rod of the control cylinder, and the ends of the two folding rods away from the first strip and the second strip are both slidably supported on the top of the support panel.

[0016] As a further improvement of the present 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 end surface of the first strip, the output end of the electric rod is connected to the side end surface of the second strip, and a telescopic rod is connected between the first strip and the second strip.

[0017] As a further improvement of the present technical solution, a cover plate is fixedly mounted on the top of each of the first and second strips close to the regulating cavity, and the two cover plates are in a fitted state.

[0018] As a further improvement of the present technical solution, the surfaces of the first strip and the second strip are both provided with rounded corners, which can reduce the damage to the lining cloth caused by the stretching of the first strip and the second strip.

[0019] As a further improvement of the present technical solution, the ends of the two covering plates away from the first strip plate and the second strip plate are both provided with bevel angles.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this lining cloth multi-dimensional mechanical properties testing machine, during the placement phase of the lining cloth mechanical properties test, there are two cloth winding rollers, namely the cloth-releasing roller and the cloth-collecting roller. The cloth-releasing roller is responsible for releasing the lining cloth, while the cloth-collecting roller is used to rewind the lining cloth. During the test, the lining cloth at the middle end of the cloth-releasing roller and the cloth-collecting roller is tested. At the same time, with the help of the side clamping group fixed to the side end of the hollow frame, the lining cloth is stabilized from multiple directions. When the lining cloth is placed, the support assembly located in the middle of the hollow frame is in the lowest position, which can support the middle part of the lining cloth and effectively reduce the unevenness of the lining cloth when it is placed.

[0022] After the lining cloth is placed and fixed, the test begins in the initial stage. Driven by the control cylinder, the support assembly begins to lift and pass through the hollow frame. During this process, the support assembly pushes and pulls the lining cloth on the surface of the hollow frame. Since the middle end of the lining cloth is pulled and lifted, and the surrounding areas are fixed by the cloth control mechanism, the lining cloth can be pulled in multiple directions simultaneously, such as front, back, left, right, and up and down. In this way, multi-dimensional simultaneous testing can be achieved without having to place and fix the lining cloth multiple times.

[0023] Interlinings that pass one round of testing will then enter the final testing phase. Under the control of the adjustment component, the support assembly will further expand, thereby exerting greater pressure and pulling on the interlining within the same space, increasing the testing intensity. During the step-by-step testing process, the interlining can gradually adapt to different degrees of pulling force and be tested in a state where its mechanical properties are fully demonstrated. This not only improves the accuracy of the overall test results, but also effectively reduces the possibility of damage to the interlining due to excessive pulling force in the first time.

[0041] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] For examples, see Figure 1-Figure 2 As shown, the purpose of this embodiment is to provide a lining cloth multi-dimensional mechanical property testing machine, 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, and 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 connected to the middle of the hollow frame 11;

[0043] The surface of the hollow frame 11 is provided with a cloth control mechanism 2 for clamping the lining cloth to be tested. The cloth control mechanism 2 includes two cloth winding rollers 21. The two cloth winding rollers 21 are respectively located at the top of the two ends of the hollow frame 11. The middle of the hollow frame 11 is clamped with a side clamping group 22. The side clamping group 22 is used to clamp and fix the side ends of the lining cloth;

[0044] The middle support mechanism 3 is installed inside the middle cavity 13. The middle support mechanism 3 includes a support platform assembly 31. An adjustment assembly 32 is installed inside the support platform assembly 31. When the support platform assembly 31 is located at the lowest end, it can provide auxiliary support for the middle end of the lining cloth during the winding and conveying process of the lining cloth;

[0045] When the lining cloth undergoes a round of testing, the support assembly 31 is lifted and passes through the interior of the hollow frame 11 to pull and lift the middle end of the lining cloth. Combined with the clamping of the lining cloth end by the side clamping group 22 and the cloth winding roller 21, the support assembly 31 can perform mechanical property testing on the lining cloth in multiple dimensions. After a round of testing on the lining cloth, the adjustment assembly 32 expands the support assembly 31, and the lining cloth can be pressurized and tested again.

[0046] The lining cloth that needs to be tested for mechanical properties first needs to be clamped at its ends by the side clamping group 22. The specific structure of the side clamping group 22 is disclosed below. The side clamping group 22 includes a fixed plate 221, and a clamping plate 222 is fixedly installed on the top of the fixed plate 221. A clamping cavity 223 is formed inside the clamping plate 222. A plurality of clamping wheels 224 are rotatably provided at the top and bottom of the clamping cavity 223. The multiple clamping wheels 224 at the upper end operate synchronously, and the multiple clamping wheels 224 at the lower end operate synchronously.

[0047] See Figure 3 Combined with Figure 4 and Figure 5 As shown, among the two cloth-winding rollers 21, one is a cloth-releasing roller and the other is a cloth-collecting roller. Both the cloth-releasing roller and the cloth-collecting roller are driven by a motor (not shown in the figure). A fixed plate 221 is provided at the side end of the hollow frame 11. A clamping plate 222 is fixedly installed on the top of the fixed plate 221 for clamping the side end of the lining cloth. A plurality of clamping wheels 224 are provided at the upper and lower ends of the inner cavity of the clamping cavity 223. The ends of the plurality of clamping wheels 224 at the same end are connected to gears, and these gears are connected to each other by a chain. Driven by a micro motor, the plurality of gears at the same end can rotate synchronously, thereby realizing multiple The clamping wheels 224 rotate synchronously (using existing technology, which will not be described here and is not shown in the figure); when the lining cloth is rolled up, the upper clamping wheel 224 and the lower clamping wheel 224 will rotate in opposite directions, for example, the upper clamping wheel 224 rotates forward clockwise, and the lower clamping wheel 224 rotates backward counterclockwise. This reverse rotation can ensure that the lining cloth clamped between the upper and lower clamping wheels 224 is smoothly advanced forward. In this way, after completing the test of a section of lining cloth, there is no need to disassemble the device. By combining the two cloth winding rollers 21 and the side clamping group 22, the lining cloth located in the middle of the hollow frame 11 can be replaced and the test of the next section of lining cloth can be directly carried out.

[0048] It is worth mentioning that the fixing plate 221 is movably mounted on the end of the hollow frame 11 (e.g., fixed by bolts). In this way, if the width of the lining cloth being tested changes, the position of the fixing plate 221 can be adjusted to achieve precise clamping of the side end of the lining cloth, thereby ensuring the stability of the lining cloth during the entire test process, thereby greatly improving the applicability of the device and the accuracy of the test.

[0049] There are multiple side clamping groups 22 , which are respectively mounted on the two end surfaces of the hollow frame 11 away from the cloth winding roller 21 , and can clamp and fix the two sides of the lining cloth at multiple locations.

[0050] Considering the clamping effect of the clamping wheel 224 on the end of the lining cloth, a plurality of clamping strips 225 are fixedly installed on the surface of the plurality of clamping wheels 224. The plurality of clamping strips 225 are used to enhance the clamping force on the lining cloth.

[0051] The improvement lies in: combining Figure 9It 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. They cooperate with the two cloth winding rollers 21 to clamp the test lining cloth from multiple directions, greatly improving the clamping stability. Figure 5 As shown, a plurality of gripping strips 225 are provided on the surface of the clamping wheel 224. The material of the gripping strips 225 is usually selected from rubber or silicone with high friction, which further enhances the clamping effect on the lining cloth and reduces the situation where the lining cloth escapes from the clamping wheel 224 during testing. The gripping strips 225 are configured to have high friction rubber or silicone and have a certain degree of elasticity. The elastic material will deform when subjected to pressure, thereby fitting more closely to the surface of the lining cloth, increasing the contact area, and better stabilizing the lining cloth.

[0052] The specific structure of the support assembly 31 is disclosed below. The support assembly 31 includes a first strip 311 and a second strip 312. A folding rod 314 is fixedly installed at the bottom 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.

[0053] The middle branch mechanism 3 also includes a control cylinder 33 fixedly installed in the middle of the middle cavity 13, and a support panel 34 is fixedly installed at the end of the piston rod of the control cylinder 33. The ends of the two folding rods 314 away from the first strip 311 and the second strip 312 are both slidably supported on the top of the support panel 34.

[0054] Combine Figure 10 As shown, the first strip 311 and the second strip 312 are arranged in parallel, and a folding rod 314 is fixedly installed at the bottom of both, 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 using existing technology, not shown in the figure), as shown in FIG. Figure 6 During the initial placement of the lining cloth, the first strip 311 and the second strip 312 can effectively share the weight of the lining cloth, reducing premature sagging of the middle portion of the lining cloth due to its own weight, ensuring that the lining cloth remains relatively flat at the initial stage of placement, and providing a good foundation for subsequent testing. At the same time, the support provided by the first strip 311 and the second strip 312 on the lining cloth cooperates with the side clamping group 22, acting on the lining cloth from different directions, further enhancing the clamping effect of the lining cloth, making the lining cloth more stable throughout the test process, reducing the occurrence of displacement or loosening, and thereby improving the accuracy and reliability of the test results;

[0055] Depend on Figure 7It can be seen that in the initial stage of the lining cloth mechanical property test, the control cylinder 33 exerts force to drive the support panel 34 and the first and second parallel plates 311 and 312 to move upward synchronously. As they rise, the first and second plates 311 and 312 can smoothly pass through the middle of the hollow frame 11, thereby pulling and lifting the middle end of the lining cloth. At this time, the lining cloth is firmly fixed on all sides by the cloth winding rollers 21 and the side clamping group 22, while the middle end is pulled upward. From the principle of mechanics, when an object is subjected to multiple forces in different directions, its internal stress distribution will undergo complex changes. In this multi-dimensional pulling situation, various parts of the lining cloth are subjected to tension in different directions, which can fully simulate the stress scenarios that the lining cloth may face in actual use. In this way, through this testing method, the effect of multi-dimensional mechanical testing can be achieved, and the mechanical properties of the lining cloth under different force directions, such as tensile strength and tear resistance, can be evaluated. This is one round of testing.

[0056] During the fabric testing process, the tester can make a preliminary judgment by directly observing the texture changes on the surface of the lining cloth. For example, if the lining cloth has obvious tear lines on the surface or the texture deformation is too large, it can intuitively reflect the performance of the lining cloth under the corresponding force direction. On the other hand, a detection machine (not shown in the figure) can also be installed on the top of the workbench 1 to use existing technology to perform more accurate detection and analysis of the lining cloth. These detection methods can accurately evaluate the mechanical properties of the lining cloth under different force directions, such as tensile strength, tear resistance, etc.

[0057] The adjustment assembly 32 includes an electric rod 321 arranged in the adjustment cavity, one end of the electric rod 321 is fixedly connected to the side surface of the first strip 311, and the output end of the electric rod 321 is connected to the side surface of the second strip 312. A telescopic rod 322 is connected between the first strip 311 and the second strip 312, and the telescopic rod 322 is used to connect and support the first strip 311 and the second strip 312.

[0058] Combine Figure 8 As shown, when the lining cloth that has passed the first round of testing enters the second round of testing, the electric rod 321 is activated to apply a thrust to the second strip 312, thereby widening the distance between the first strip 311 and the second strip 312. It is worth noting that this process does not require the first strip 311 and the second strip 312 to be lifted again, thus achieving a second pulling test on the lining cloth in a limited space.

[0059] The mechanical properties of materials are anisotropic and nonlinear. Different tension distributions will cause the fiber structure inside the lining cloth to deform and slip to varying degrees. Increasing the spacing between the first strip 311 and the second strip 312 subjects the lining cloth to a tension distribution different from that in the first round of testing. This allows for a more comprehensive assessment of the stress conditions the lining cloth may face in various actual usage scenarios. By changing the stress boundary conditions of the lining cloth, the stress and strain state within the lining cloth changes. By testing the mechanical response of the lining cloth under such changes, a deeper understanding of its mechanical properties can be achieved, providing richer data support for precise product quality control and performance optimization.

[0060] This two-step testing method, using different tensile forces, protects the lining by preventing it from being subjected to excessive tensile forces at once, significantly reducing damage, extending the test period, and lowering testing costs. From the perspective of simulating the actual use environment, it can better simulate the different tensile forces that the lining may be subjected to in real-life usage scenarios. In daily life or industrial applications, the tensile forces experienced by the lining are not constant. By testing the lining in two rounds at different tensile forces, we can more closely resemble the actual stress process, thereby improving the accuracy of the test results.

[0061] Since it is necessary to ensure that the lining cloth can maintain a stable state in each test link when conducting mechanical property testing on the lining cloth, a cover plate 313 is fixedly installed on the top of the first plate 311 and the second plate 312 on the side close to the adjustment cavity, and the two cover plates 313 are in a fit state.

[0062] Improvements include: Figure 10 As shown, a cover plate 313 is fixedly installed on the top of the first plate 311 and the second plate 312 on one side close to the adjustment cavity, and the two cover plates 313 are in a fit state, which can better support the middle part of the lining cloth, reduce the sagging of the lining cloth, and ensure that the lining cloth is always in an ideal stress state during the entire testing process, providing a strong guarantee for accurately evaluating the mechanical properties of the lining cloth.

[0063] During the mechanical property test of the lining cloth, the first and second plates 311, 312 will perform operations such as pulling on the lining cloth. If their surfaces are right-angled, the right-angled edges will easily generate large friction with the lining cloth during the stretching process, and may even hook the lining cloth fibers, thereby causing scratches, tears, and other damage to the lining cloth. Therefore, the surfaces of the first and second plates 311, 312 are both provided with rounded corners 4, which can reduce the damage to the lining cloth caused by the stretching of the first and second plates 311, 312.

[0064] The ends of the two covering plates 313 away from the first strip 311 and the second strip 312 are both provided with a bevel angle 41 .

[0065] Improvements include: Figure 8 Combined with Figure 10 As shown, the surfaces of the first strip 311 and the second strip 312 are both provided with rounded corners 4. The rounded corners 4 can effectively disperse stress and reduce damage to the lining cloth when the first strip 311 and the second strip 312 are stretched. Similarly, when the lining cloth is stretched, if the end corners of the cover plate 313 are too sharp, similar damage will be caused to the lining cloth. Therefore, the ends of the two cover plates 313 away from the first strip 311 and the second strip 312 are both provided with beveled corners 41. The beveled corners 41 can make the contact between the cover plate 313 and the lining cloth smoother, reduce the damage to the lining cloth caused by the sharp end corners when the lining cloth is stretched, ensure that the lining cloth is not unnecessary damaged during the entire detection process, and thus ensure that the detection results are true and reliable.

[0066] In summary, the working principle of this solution is as follows: First, the lining cloth to be tested is fixed at its end angles by two cloth winding rollers 21 and multiple side clamping groups 22. During the initial lining cloth placement stage, the first strip 311 and the second strip 312 can effectively share the weight of the lining cloth, reducing premature sagging of the middle part of the lining cloth due to its own weight, ensuring that the lining cloth remains relatively flat in the initial placement, providing a good foundation for subsequent testing. At the same time, the support of the lining cloth by the first strip 311 and the second strip 312 cooperates with the side clamping groups 22 to act on the lining cloth from different directions, further enhancing the clamping effect of the lining cloth.

[0067] In the initial stage of the lining cloth mechanical property test, the control cylinder 33 exerts force to drive the support panel 34 and the first and second parallel plates 311 and 312 to move upward synchronously. As they rise, the first and second plates 311 and 312 can smoothly pass through the middle of the hollow frame 11, thereby pulling and lifting the middle end of the lining cloth. At this time, the lining cloth is firmly fixed on all sides by the cloth winding rollers 21 and the side clamping group 22, while the middle end is pulled upward. From the principle of mechanics, when an object is subjected to multiple forces in different directions, its internal stress distribution will undergo complex changes. In this multi-dimensional pulling situation, all parts of the lining cloth are subjected to tension in different directions, which can fully simulate the stress scenarios that the lining cloth may face in actual use. In this way, this testing method can achieve the effect of multi-dimensional mechanical testing and evaluate the mechanical properties of the lining cloth under different force directions. When the lining cloth that has passed the first round of testing enters the second round of testing, the electric rod 321 is activated to apply a thrust to the second plate 312, thereby increasing the distance between the first plate 311 and the second plate 312. The increased distance between the first plate 311 and the second plate 312 causes the lining cloth to be subjected to a tension distribution different from that in the first round of testing, thereby more comprehensively evaluating the force conditions that the lining cloth may face in various actual usage scenarios. By testing the mechanical response of the lining cloth under such changes, a deeper understanding of the mechanical properties of the lining cloth can be obtained, providing richer data support for precise control of product quality and performance optimization.

[0068] During the fabric testing process, the tester can make a preliminary judgment by directly observing the texture changes on the surface of the lining cloth. For example, if there are obvious tear lines on the surface of the lining cloth or the texture deformation is too large, it can intuitively reflect the performance of the lining cloth under the corresponding force direction. On the other hand, a detection machine can also be installed on the top of the workbench 1 to use existing technology to perform more accurate detection and analysis of the lining cloth. These detection methods can accurately evaluate the mechanical properties of the lining cloth under different force directions.
