Description

Technical Field

[0001] This application relates to the field of fabric testing technology, specifically to a fabric abrasion testing device and its testing method. Background Technology

[0002] In the production and use of fabrics, abrasion resistance is one of the important indicators for measuring their quality. Accurate fabric abrasion testing is of great significance for evaluating fabric quality, service life, and applicable scenarios. Therefore, fabric abrasion testing devices have emerged, such as the TABER for fabric production disclosed in CN210775098U. Abrasion testing machines, including those disclosed in CN204718908U and CN213658498U (a device for detecting abrasion in automotive interior fabrics), share the characteristic of using a horizontal turntable to rotate continuously in one direction to drive the sample to rotate and contact the friction head for abrasion testing. This method differs from the reciprocating friction conditions in actual use, resulting in discrepancies between the tested performance and the actual performance. Furthermore, it cannot meet the requirement of single sample clamping and multi-area testing, and makes it difficult to clean abrasion debris or requires a separate auxiliary structure for collection. CN213658498U uses reciprocating friction for abrasion testing, but the friction strip is soft and requires auxiliary support structures such as fixed guide pillars. The thickness of the sample affects the friction force; if the sample thickness is too small, it may not be able to contact the friction strip, and the problem of difficult abrasion debris removal also exists. Summary of the Invention

[0003] In view of this, this application provides a fabric abrasion testing device and method to solve the technical problems of existing devices being unable to achieve single sample clamping, multi-area testing, poor friction stability, and difficulty in cleaning abrasion debris.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A fabric abrasion testing device includes a base body, wherein: A first-position adjustment structure is installed on the fuselage base; The sample clamp assembly is mounted on the connecting block of the first position adjustment structure, and the samples fixed on the sample clamp assembly are distributed in the vertical direction. The wear test structure is set on the base of the machine body and located on one side of the sample. The wear test structure includes a position-adjustable swing shaft, a swing arm and an adjustable first counterweight structure fixed on the swing shaft, and a friction head for contacting the test on the swing arm. The torque applied to the swing shaft by the first counterweight structure will drive the friction head to move closer to the sample to form a certain pre-pressure.

[0005] Furthermore, the swing shaft is also provided with a second counterweight structure with adjustable counterweight. The torque applied to the swing shaft by the second counterweight structure is less than the torque applied to the swing shaft by the first counterweight structure and the direction is opposite.

[0006] Furthermore, the first and second counterweight structures are identical in structure, including a mounting rod connected to the swing shaft and at least one detachable breeding block mounted on the mounting rod.

[0007] Furthermore, the swing arm moves forward, backward, and up and down under the action of the second position adjustment structure. During the forward and backward movement, the friction head moves closer to or further away from the sample. The first position adjustment structure includes three sets of screw-operated hand-cranked slides, which enable the sample clamp assembly to move forward and backward, left and right, and up and down.

[0008] Furthermore, the swing shaft is pivotally mounted on the mounting plate, and a limit arm is also fixedly mounted on the swing shaft. The mounting plate has a limit groove that is fitted with the limit arm in a clearance fit.

[0009] Furthermore, the wear test structure also includes a stand, a trigger plate on the mounting plate, and two travel control switches on the stand that work in conjunction with the trigger plate.

[0010] Furthermore, the trigger plate is equipped with a sensor plate, and the stand is equipped with a counting sensor module located between the two limit control switches. The sensor plate and the counting sensor module work together to count the lifting frequency of the mounting plate.

[0011] Furthermore, the screw passes through the swing arm and connects to the friction head, and the friction surface of the friction head is detachably fitted with a block made of rubber or wool felt that protrudes from the friction surface.

[0012] Furthermore, the connecting block is also equipped with a force sensor capable of measuring pre-pressure by pressing against the friction head. The force sensor is located on the side of the sample clamp assembly.

[0013] In view of the fabric abrasion testing device disclosed above, this application also discloses another technical solution: A test method for the fabric abrasion testing device described in any one of the above-mentioned methods, comprising the following specific test steps: Step 01: Preparation: Replace the corresponding friction head; Step 02: Select either to set the pressure directly or to calibrate the test pressure of the sample as needed. If the test pressure of the sample needs to be calibrated, proceed to Step 03; otherwise, proceed to Step 04. Step 03: Test and calibrate the pressure value: First, move the force sensor to the friction head by manipulating the first position adjustment structure so that the friction head can press against the force sensor; second, control the swing arm to move forward and backward by the second position adjustment structure so that the friction head presses vertically against the force sensor; then adjust the weight of the first counterweight structure or the first counterweight structure and the second counterweight structure, and observe the detection value of the force sensor. Step 04: Set the required pressure value; Adjust the weight of the first counterweight structure or the first counterweight structure 64 and the second counterweight structure to obtain the required pressure value; Step 05: Determine the wear location: First, use the sample clamp assembly to fix the fabric sample; then, manipulate the first position adjustment structure to move the sample to a position that can fit against the friction head. Step 06: Wear test: Use the second position adjustment structure to control the swing arm to move up and down, which in turn drives the friction head to move up and down reciprocally to perform a wear test until the set number of friction cycles is reached; Step 07: If wear testing at multiple locations is required, repeat the above steps.

[0014] As can be seen from the above technical solution, the advantages of the present invention are: 1. The fabric abrasion testing device of this application simulates friction on a vertical plane. Through the cooperation of mechanisms such as swing arm and counterweight structure, it can detect the friction effect under different test pressures. The friction action can be adjusted to meet the friction test requirements of most samples.

[0015] 2. By setting a first counterweight structure or a first counterweight structure and a second counterweight structure with the same structure, the counterweight can be easily adjusted by increasing or decreasing the number of breeding blocks, thereby precisely controlling the pre-pressure of the friction head on the sample, stabilizing the friction force, and improving the accuracy of the test results.

[0016] 3. This application sets up a first position adjustment structure formed by three sets of screw-operated hand-cranked slides, which can enable the sample clamp assembly to move back and forth, left and right, and up and down. The test position of the sample can be flexibly adjusted according to the friction range of the friction head and the test requirements, so as to meet the requirements of one clamping of the fabric and wear testing of multiple different parts.

[0017] 4. In this application, the reciprocating movement of the friction head is used for testing, which makes the test conditions closer to the actual conditions and the test structure closer to the actual performance. Furthermore, through the cooperation of the sample clamp assembly and the winding and unwinding assembly, it can be applied to test samples of different shapes and sizes.

[0018] 5. The friction head of this application is easy to replace. By using friction heads equipped with inserts of different materials, the effects of different friction factors on the abrasion effect of the fabric can be simulated, making the test more comprehensive and accurate.

[0019] 6. Keep the test environment clean: A shavings receiving tray is set directly below the sample clamp assembly to catch the fabric abrasion, prevent shavings from falling, and keep the test environment clean and tidy. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0030] refer to Figures 1 to 7 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a fabric abrasion testing device, including a base body 1, and also including a first position adjustment structure 2, a sample clamp assembly 3, and an abrasion testing structure 6 integrated on the base body 1. It can effectively meet diverse fabric abrasion testing needs. The sample clamp assembly 3 is installed on the connecting block 21 of the first position adjustment structure 2, and the samples fixed on the sample clamp assembly 3 are distributed in the vertical direction, providing a basis for subsequent testing. The abrasion testing structure 6 is used to perform abrasion testing on the fabric samples fixed on the abrasion testing structure 6.

[0031] This application also includes a control module 8 and a display control panel. The control module 8 can precisely control various operating actions of the device based on the test parameters input from the display control panel. At the same time, the display control panel displays test parameters and other information in real time, allowing operators to keep track of the test status at any time and achieve convenient and efficient test operations.

[0032] like Figure 4 As shown in this application, the wear test structure 6 is set on the body base 1 and located on one side of the sample. The wear test structure 6 includes a position-adjustable swing shaft 61, a swing arm 62 and a first counterweight structure 64 with adjustable counterweight are fixed on the swing shaft 61. A friction head 63 for contacting the test is connected to the swing arm 62. The torque applied to the swing shaft 61 by the first counterweight structure 64 will drive the friction head 63 to move closer to the sample to form a certain pre-pressure, ensuring that the initial conditions of the wear test are stable and reliable, and that the pre-pressure is stable and reliable during the test.

[0033] To facilitate pre-pressure adjustment and achieve a certain balancing effect, preventing deformation of the swing shaft 61 caused by prolonged unilateral stress, which could affect the device's functionality and lifespan, the swing shaft 61 is equipped with an adjustable second counterweight structure 65. The torque applied to the swing shaft 61 by the second counterweight structure 65 is less than the torque applied to the swing shaft 61 by the first counterweight structure 64 and is in the opposite direction. The first counterweight structure 64 and the second counterweight structure 65 form a mechanism for horizontal adjustment of the swing arm 62. By adjusting the left and right positions of the counterweights, the swing arm 62 is kept in a balanced horizontal position, ensuring the accuracy and stability of the friction force. This design effectively balances the force on the swing shaft 61, extends the device's lifespan, and allows for easy fine-tuning of the pre-pressure by adjusting the difference in counterweights on both sides. This reduces the pressure difference between adjacent pressure values, resulting in better accuracy in fabric abrasion performance testing.

[0034] In this application, the first counterweight structure 64 and the second counterweight structure 65 have the same structure, including a mounting rod connected to the swing shaft 61 and at least one seed block that can be detached and mounted on the mounting rod. The counterweight can be adjusted by increasing or decreasing the number of seed blocks, thereby precisely controlling the magnitude of the pre-pressure. The weight specifications of the seed blocks can be the same or different, and each seed block is marked with a force value.

[0035] Specifically, the installation method of the insemination blocks can refer to the installation method of the counterweights in a barbell, so that the number of insemination blocks used can be easily adjusted.

[0036] In this application, the swing shaft 61 is pivotally mounted on the mounting plate 68, and a limit arm 66 is also fixedly connected to the swing shaft 61. The mounting plate 68 has a limit groove 67 that is fitted with the limit arm 66 with a clearance, which can limit the swing range of the swing shaft 61 and prevent the friction head 63 from colliding with other positions due to excessive swing amplitude during reciprocating movement. This effectively prevents damage to the device and potential dangers, and ensures the safety and stability of the testing process.

[0037] In this application, the wear test structure 6 also includes a stand 69, a trigger plate 611 on the mounting plate 68, and two stroke control switches 610 on the stand 69 that work in conjunction with the trigger plate 611 to control the maximum lifting stroke of the swing arm 62. In turn, by controlling the lifting stroke of the swing arm 62, the movement stroke of the friction head 63 is controlled to ensure that the action range of the wear test is accurate.

[0038] In this application, the trigger plate 611 is also provided with a sensing plate 612, and the stand 69 is also provided with a counting sensing module 613 located between two limit control switches 610. The sensing plate 612 and the counting sensing module 613 work together to count the lifting frequency of the mounting plate 68, thereby measuring the number of frictions. When the number of frictions reaches the set value, the control module 8 can be used to control the machine to stop, thus realizing the automation and precision of the testing process.

[0039] like Figure 7 As shown in this application, to facilitate the replacement of the friction head 63, a screw 616 passes through the swing arm 62 and connects to the friction head 63. This connection method is firm and easy to disassemble. A rubber or felt insert 631 protruding from the friction surface is separably embedded on the friction surface of the friction head 63. By replacing different types of friction heads 63, the friction factor applied to the sample can be changed, thereby testing the wear effect of different friction factors on the sample.

[0040] Specifically, the friction head 63 can be a first friction head 63a, a second friction head 63b, or a third friction head 63c. The inserts 631 of the first friction head 63a and the second friction head 63b are rubber rubbing heads with different coefficients of friction, and the inserts 631 of the third friction head 63c are wool felt rubbing heads, thus meeting diverse testing needs.

[0041] In order to accurately adjust the friction force between the friction head 63 and the sample, it is necessary to precisely adjust the pressure applied by the friction head 63 to the sample. Therefore, this application also provides a force sensor 4 on the connecting block 21, which can press against the friction head 63 to measure the pre-pressure. The force sensor 4 is located on the side of the sample clamp assembly 3. The contact pressure between the friction head 63 and the friction platform is calibrated by setting the force sensor 4. It can also be inspected and calibrated before the equipment leaves the factory to ensure the accuracy and reliability of the test results. The force sensor 4 can be a pressure sensor from the prior art, which is technically mature and has stable performance.

[0042] like Figure 5 and Figure 6As shown in this application, the sample clamp assembly 3 includes a fixed back plate 31 connected to the connecting block 21. The fixed back plate 31 has mounting holes of various specifications for mounting different sample clamps 32. This design allows the sample clamps 32 to be flexibly selected and installed according to the shape and size of different samples. The sample clamps 32 can be a vise 32a, a clamping device 32b, or a T-head 32c. Different types of clamps can also be clamped using the vise 32a to firmly fix various samples and ensure the stability of the samples during the test. Qualitatively, clamping device 32b is suitable for flat square plate-like samples. The clamping arm of clamping device 32b firmly presses the sample onto the test plane. T-head 32c is suitable for irregularly shaped samples with square holes. For irregularly shaped samples of different sizes, the size of T-head 32C needs to be adjusted to meet the clamping and fixing of irregularly shaped samples. Bench vise 32a is suitable for conventional samples. The clamping plates on the bench vise are used to clamp the face or edge of the sample. By tightening the handle of the bench vise, the clamping plates can be used to clamp the sample firmly.

[0043] In this application, the first position adjustment structure 2 includes three sets of screw-cranked slides, enabling the sample clamp assembly 3 to move forward and backward, left and right, and up and down. Since the friction range of the friction head 63 is fixed, after the sample is fixed, different parts of the sample friction can be adjusted by the screw-cranked slides according to the test requirements to achieve multi-point and all-round wear testing of the sample. The swing arm 62 performs forward, backward, and lifting movements under the action of the second position adjustment structure. During the forward and backward movement, the friction head 63 moves closer to or further away from the sample, further enriching the test action modes. The screw-cranked slides are equipped with handles that achieve a locking function. After the position of the sample clamp assembly 3 is adjusted to the correct position, the locking handle at the hand crank of the screw-cranked slide is tightened to hold the screw of the screw-cranked slide, thus stabilizing and fixing the position of the sample clamp assembly 3.

[0044] Specifically, in the first position adjustment structure 2, the uppermost screw-cranked slide is arranged vertically, and the lowermost screw-cranked slide is arranged in the front-back direction. When the sample clamp assembly 3 moves back and forth, it can move closer to or further away from the friction head 63, making it convenient to adjust the relative position of the sample friction position and the friction head 63. The second position adjustment structure includes a translation drive mechanism 615 set on the machine body base 1 and a lifting drive mechanism 614 set on the translation frame of the translation drive mechanism 615. Both the translation drive mechanism 615 and the lifting drive mechanism 614 are electric screw-slide mechanisms. Screw-slide mechanisms have the advantages of high transmission accuracy and smooth movement, which can ensure that the swing arm 62 moves accurately and reliably.

[0045] In this application, since the sample is arranged vertically, the friction head 63 is perpendicular to the sample and close to the horizontal direction, so that the abrasive can fall automatically and separate from the sample under the action of gravity. The separation facilitates the collection of abrasive. A abrasive receiving plate 7 is placed on the machine body base 1 directly below the sample clamp assembly 3 to receive the debris generated by the fabric grinding, keep the test environment clean and tidy, and also facilitate the collection and analysis of abrasive, providing data support for subsequent research.

[0046] In this application, the device also includes a winding and unwinding assembly 5 disposed on the base body 1, which can be used for abrasion testing of different areas of long strip fabric. In use, the winding and unwinding of the winding and unwinding assembly 5 and the lifting and lowering adjustment of the first position adjustment structure 2 are used to move the sample clamp assembly 3 up and down to move different test areas to the position corresponding to the friction head 63 for abrasion testing, which greatly improves the applicability and testing efficiency of the device.

[0047] In summary, this fabric abrasion testing device has the advantages of reasonable design, comprehensive functions, convenient operation, and accurate testing. It can meet the abrasion testing needs of different types of fabrics under different conditions, and provides strong support for fabric quality inspection and research and development.

[0048] Example 2 In view of the fabric abrasion testing device disclosed in Embodiment 1, this application further discloses a testing method for the fabric abrasion testing device described in Embodiment 1, based on Embodiment 1. The specific testing steps are as follows: Step 01: Preparation: Select the appropriate friction head 63 according to the test requirements, and install the friction head 63 on the swing arm 62 with screws 616; Step 02: Select either to set the pressure directly or to calibrate the test pressure of the sample as needed. If the test pressure of the sample needs to be calibrated, proceed to Step 03; otherwise, proceed to Step 04. Step 03: Test and calibrate the pressure value: First, manipulate the three sets of hand-cranked slides of the first position adjustment structure 2 to move the force sensor 4 to the friction head 63 (one side of the friction head 63), so that the friction head 63 can press against the force sensor 4. Secondly, the translation drive mechanism 615 and the lifting drive mechanism 614 of the second position adjustment structure control the swing arm 62 to move forward and backward, so that the friction head 63 presses vertically against the force sensor 4. Then, the weight of the first counterweight structure 64 (when only one counterweight structure is used) or the first counterweight structure 64 and the second counterweight structure 65 (when two counterweight structures are used) is adjusted by adjusting the number of weights on each side. As the weight is adjusted, the error between the detected value of the force sensor 4 and the pressure value generated by the actual counterweight structure is observed. Step 04: Set the required pressure value; Adjust the weight of the first counterweight structure 64 (when only one counterweight structure is used) or the first counterweight structure 64 and the second counterweight structure 65 (when two counterweight structures are used) to obtain the required pressure value, and then obtain the actual pressure value based on the calibration error; Step 05: Determine the location of wear: First, the fabric sample is fixed by using the vise 32a of the sample clamp assembly 3 or the auxiliary tool or clamping device 32b or T-head 32c installed on the vise 32a to ensure that the sample is firmly installed. Then, manipulate the three sets of hand-cranked slides of the first position adjustment structure 2 to move the sample to a position that can fit with the friction head 63. During the adjustment process, pay attention to the relative position of the sample and the friction head 63 to ensure good contact between the sample and the friction head 63. Step 06: Wear Test First, set the test parameters such as the number of friction cycles on the display control panel; Secondly, the lifting drive mechanism 614 of the second position adjustment structure controls the lifting movement of the swing arm 62, which drives the friction head 63 to reciprocate to perform wear testing on the sample. During the test, the sensing plate 612 on the trigger plate 611 cooperates with the counting sensing module 613 to automatically measure the lifting frequency of the mounting plate 68, thereby accurately measuring the number of frictions until the set number of frictions is reached. Finally, once the set number of friction cycles is reached, the device automatically stops operating; Step 07: Multi-location wear test: If wear tests need to be performed on multiple locations of the sample while the pre-pressure remains constant, repeat steps 5 and 6 above. Adjust the position of the sample by manipulating the first position adjustment structure 2 so that the friction head 63 can perform wear tests on different parts of the sample. If wear tests with different pressures are required at multiple locations of the sample, repeat steps 4, 5, and 6 above. Adjust the position of the sample by manipulating the first position adjustment structure 2 so that the friction head 63 can perform wear tests on different parts of the sample.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
