Description

Technical Field

[0001] This invention relates to the field of abrasion resistance testing technology, specifically to a device for testing the abrasion resistance of PTFE fabric. Background Technology

[0002] PTFE cloth is a general term for all flexible fabrics containing PTFE material, including composite coated cloth, pure PTFE woven cloth, ePTFE membrane filter cloth, and filter bags. During the production of PTFE cloth, its abrasion resistance needs to be tested to ensure product quality. Patent CN210375932U discloses an abrasion testing machine. The sample is cut and the fabric is fixed by a hollow pressure plate. The fabric is driven to rotate by a testing mechanism so that it comes into contact with the abrasion wheel to test the abrasion resistance of the fabric. While the above process can enable the testing of samples, each test requires manual time to cut samples of a certain size before clamping them for testing. This may require cutting multiple samples from the same roll of fabric in batches when conducting multiple parallel comparison tests. The preparation time is much longer than the abrasion resistance test itself, resulting in a significant extension of the test time. Summary of the Invention

[0016] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] Example 1: As Figures 1-7 As shown, this application provides a PTFE fabric abrasion resistance testing device, including a testing platform 1, on which a testing component 2 is provided. The testing component 2 is suitable for abrasion resistance testing of PTFE fabric. Specifically: Test component 2 includes a fixing block 33 fixedly mounted on the top of the test platform 1, on which a rotating shaft (not shown in the figure) is rotatably mounted, and a servo motor 39 is fixedly mounted on the bottom of the test platform 1. Figure 6 (as shown) The output end of the servo motor 39 is fixedly connected to the rotating shaft, and a rotating block 32 is fixedly installed on the top of the rotating shaft. Thus, under the drive of the servo motor 39, the rotating shaft is driven to rotate on the fixed block 33, and the rotating block 32 is driven to rotate. Continue to refer to Figure 2 A winding section 291 is provided on the rotating block 32. The winding section 291 includes a first bracket 28 fixedly installed at one end of the rotating block 32. A stepper motor is provided inside the first bracket 28. A first mounting plate (not shown in the figure) is installed at the output end of the stepper motor. A winding roller 29 is detachably installed on the first mounting plate. Thus, driven by the stepper motor, the first mounting plate rotates, which in turn drives the take-up roller 29 to rotate. Continue to refer to Figure 5 A second bracket 37 is fixedly installed at the other end of the rotating block 32. A second mounting plate is rotatably installed on the second bracket 37. A unwinding roller 34 is detachably installed on the second mounting plate. Therefore, during use, the unwinding roller 34 with the fabric to be tested wrapped around it can be installed on the second mounting plate, and one end of the fabric can be connected to the winding roller 29, so that the fabric can be wound up when the winding roller 29 rotates. Continue to refer to Figure 2 and Figure 3 A first transition roller 35 is mounted on the rotating block 32 on the opposite side of the unwinding roller 34 and the take-up roller 29, and a second transition roller 36 is mounted on the rotating block 32 above the corresponding first transition roller 35. It should be noted that when the fabric on the unwinding roller 34 is connected to the take-up roller 29, the fabric on the unwinding roller 34 can first pass through the lower surface of the first transition roller 35 corresponding to the unwinding roller 34, then pass through the upper surface of the corresponding second transition roller 36, pass through the surface of the test plate 38, and then pass through the upper surface of the second transition roller 36 and the lower surface of the first transition roller 35 corresponding to the take-up roller 29 in sequence before connecting with the take-up roller 29 and giving it a certain tension. It should be noted that in this application, the fabric wound on the unwinding roller 34 will be first marked in segments, and each segment of fabric will be weighed before being wound on the unwinding roller 34. This allows different segments of fabric to be located on the surface of the test disc 38, so that different segments of the same fabric can be tested for abrasion resistance in subsequent abrasion resistance tests. Continue to refer to Figures 1-5 The testing station 1 is also provided with a testing unit 201, which includes a round seat 301 fixedly installed on the rotating block 32. The round seat 301 is provided with a testing disk 38, which is located between the take-up roller 29 and the unwind roller 34. It should be noted that the highest points of the two second transition rollers 36 are both lower than the highest point of the test disc 38, so that the fabric passing through the surface of the test disc 38 can be flatly attached to the surface of the test disc 38 to determine the test area. A support frame 21 is fixedly installed on the testing table 1. A cylinder 22 is fixedly installed on the support frame 21. A push rod 24 is fixedly installed on the output end of the cylinder 22. A disc 27 is fixedly installed on the push rod 24. The disc 27 and the test disc 38 are on the same axis. Thus, driven by cylinder 22, the push rod 24 drives the disc 27 to move up and down in the vertical direction to move closer to or away from the test disc 38; Continue to refer to Figure 6 and Figure 7 A cylinder 271 is rotatably mounted on the disc 27. The bottom of the cylinder 271 is provided with a step 273 that is adapted to the outer ring of the test disc 38. When the disc 27 moves up and down, it drives the cylinder 271 to move up and down. During the movement, the outer ring of the test disc 38 enters the step 273. At this time, the cylinder 271 will press the fabric on the surface of the test disc 38 downward and "circle" the test area under the action of the cylinder 271 until the step 273 contacts the surface of the test disc 38 to press the fabric. Two sets of mounting posts 25 are slidably arranged on the disk 27. Friction wheels 310 are rotatably mounted on the bottom of the mounting posts 25, and bosses 26 are fixedly arranged on the mounting posts 25, which are located above the disk 27. In the initial state, the bottom of the boss 26 is in contact with the top of the disc 27 under the action of gravity. At this time, the friction wheel 310 will extend out of the bottom of the cylinder 271. When the disc 27 moves the cylinder 271 downward, it will drive the friction wheel 310 to move synchronously through the mounting column 25 until the friction wheel 310 is in contact with the fabric on the test disc 38. At this time, the test disc 38 will support the friction wheel 310 and the mounting column 25. Since the mounting column 25 is slidably set on the disc 27, as the disc 27 continues to move downward, the mounting column 25 and the friction wheel 310 are held in place by the test disc 38, while the disc 27 will move downward along the surface of the mounting column 25 until the step 273 contacts the test disc 38 and presses the fabric. At the same time, the friction wheel 310 can exert a certain pressure on the fabric. Screws 312 are fixedly installed on the top of both sets of mounting columns 25. Counterweights 311 are detachably installed on the screws 312. Different pressures can be applied to the fabric by replacing the counterweights 311 in different places. Two sets of extension blocks 272 are provided on the outer ring of the cylinder 271. The extension blocks 272 are provided with positioning holes (not shown in the figure), and the rotating block 32 is provided with positioning rods 31 that are adapted to the two sets of positioning holes. Figure 5 (as shown) In the initial state, the positioning hole and the positioning rod 31 are on the same vertical axis. When the disc 27 and the cylinder 271 move downward, the extension block 272 moves until the positioning rod 31 is inserted into the positioning hole. At this time, the positioning rod 31 restricts the extension block 272, thereby restricting the cylinder 271. When the rotating block 32 rotates, the cylinder 271 will rotate synchronously on the disc 27 through the restriction of the positioning rod 31 and the extension block 272, thereby driving the fabric to rotate. At this time, the fabric will generate friction with the friction wheel 310. It should be noted that the friction wheel 310 is arranged along the tangent of the circumference of the test disc 38, so that the friction wheel 310 can be driven to rotate by friction when the fabric rotates. Continue to refer to Figure 1 An equipment box 23 is also fixedly installed on the testing station 1. The equipment box 23 is equipped with a PLC control system. The cylinder 22, servo motor 39 and stepper motor are all connected to the PLC system. The equipment box 23 is equipped with a matching control button, so that the cylinder 22, servo motor 39 and stepper motor can be turned on and off by controlling the control button. In summary, when multiple sets of comparative tests are required on the fabric, the segmented, marked, and weighed fabric is wound around the unwinding roller 34 and installed on the second mounting plate. Then, one end of the fabric is passed sequentially through the first transition roller 35, the second transition roller 36, and the surface of the test plate 38 on the side of the unwinding roller 34, and then through the second transition roller 36 and the first transition roller 35 on the side of the take-up roller 29 before being fixed on the take-up roller 29. Driven by a stepper motor, the take-up roller 29 drives the corresponding marked fabric to contact the surface of the test plate 38. Subsequently, the cylinder 22 drives the disc 27 and the cylinder 271 to move downward to select the test area and make the friction wheel 310 contact the fabric surface. The servo motor 39 starts, driving the rotating block 32 to rotate, which in turn drives the fabric to rotate through the take-up roller 29, unwind roller 34, test disc 38, and cylinder 271. The fabric is then rubbed by the friction wheel 310. After the friction is completed, the take-up roller 29 can move other sections of fabric to the surface of the test disc 38 for further friction. Multiple sets of friction are performed. After the friction is completed, the abrasion resistance of each marked section of fabric is calculated by measuring the front and back mass using a calculation formula (as mentioned in GB / T21196.3-2007 Textiles Martindale Method for Determination of Abrasion Resistance of Fabrics Part 3: Determination of Mass Loss, which describes the method of testing abrasion resistance by mass loss). Wear resistance can be evaluated using the wear resistance index. In this embodiment, for example, A = n / Δm, where A is the wear resistance index, in milligrams per friction (times / mg), n is the total number of friction cycles, in cycles, and Δm is the mass loss of the sample under the total number of friction cycles, in milligrams (mg).

[0018] This allows for the avoidance of manually cutting and clamping samples multiple times when multiple parallel comparison tests are required, thereby reducing the preparation time before testing.

[0019] Example 2: Due to the different uses of PTFE fabrics, such as home textiles or industrial PTFE fabrics, the used fabrics need to be washed in order to be recycled during long-term use. The most common washing method is water washing. During the water washing process, especially manual water washing, the wet fabric will continuously rub against the ridges on the washboard. This friction may cause wear and tear on the fabric. Although the above process can test the PTFE fabric, it cannot test the friction data of the wet fabric.

[0020] like Figures 8-9As shown, in order to solve this problem, a simulation component 4 is provided on the test component 2. The simulation component 4 includes a drive motor (not shown in the figure) disposed inside the friction wheel 310. A turntable 47 is installed at the output end of the drive motor, and a cavity 45 is opened inside the friction wheel 310. The turntable 47 is located inside the cavity 45, so that the turntable 47 is driven to rotate inside the cavity 45 under the drive of the drive motor. Multiple sets of arc grooves 48 are formed on the turntable 47. A slide rod 49 is slidably arranged inside the arc groove 48. For ease of explanation, the end of the arc groove 48 closer to the center of the turntable 47 is defined as the inner end 5, and the end of the arc groove 48 away from the center is defined as the outer end 51. In the initial state, the slide rod 49 is located at the inner end 5. When the turntable 47 rotates, it will drive the slide rod 49 to slide from the inner end 5 to the outer end 51 in the arc groove 48. Specifically, the inner end 5 of the arc groove 48 is set close to the center of the turntable 47, and the outer end 51 of the arc groove 48 is set away from the center of the turntable 47.

[0021] A connecting block 44 is fixedly installed on the slide rod 49, and multiple sets of through grooves 46 adapted to the corresponding connecting block 44 are opened inside the friction wheel 310. The through grooves 46 are arranged radially along the friction wheel 310. The connecting block 44 is slidably disposed in the corresponding through groove 46. In the initial state, the connecting block 44 is retracted inside the through groove 46. When the slide rod 49 slides from the inner end 5 to the outer end 51 of the arc groove 48, it will drive the connecting block 44 to slide in the through groove 46 in a direction away from the center of the turntable 47. Multiple sets of grooves 52 are formed on the circumferential surface of the friction wheel 310. A protrusion 43 is slidably arranged inside the groove 52. The protrusion 43 is fixedly connected to the end of the corresponding connecting block 44 away from the turntable 47.

[0022] In this embodiment, the protrusion 43 may be arranged in an arc shape on the outer side of the turntable 47 in the radial direction.

[0023] In the initial state, when the slide rod 49 is located at the inner end 5 of the groove, the protrusion 43 is retracted inside the groove 52. When the slide rod 49 slides from the inner end 5 to the outer end 51 of the groove in the arc groove 48, it will drive multiple sets of connecting blocks 44 to move along the radial direction of the turntable 47 away from the center of the turntable 47, and drive the protrusion 43 to extend out of the circumferential surface of the friction wheel 310. At this time, there are multiple protruding protrusions 43 on the circumferential surface of the friction wheel 310. In this embodiment, during actual testing, the sliding distance of the slide rod 49 in the arc groove 48 can be set according to requirements. It is not necessary to slide to the outer end 51 of the groove. It is sufficient for the protrusion 43 to extend slightly out of the friction wheel 310.

[0024] During the test, the cylinder 22 extends and drives the disc 27 and the cylinder 271 to move downward through the push rod 24, which in turn drives the friction wheel 310 and the convex strip 43 to move downward until the convex strip 43 contacts the fabric and the cylinder 271 presses the fabric. A power motor (not shown in the figure) is also installed inside the mounting column 25. The output end of the power motor can be connected to the friction wheel 310 through a one-way bearing. Thus, during the test of Embodiment 1, due to the setting of the one-way bearing, the rotation of the fabric can still drive the friction wheel 310 to rotate, and the wear resistance performance test of the fabric can be realized. For ease of explanation, the direction of rotation of the friction wheel 310 driven by the fabric is defined as forward rotation, while the direction of rotation of the friction wheel 310 driven by the power motor is defined as reverse rotation. In this embodiment, when the convex strip 43 comes into contact with the fabric, the power motor drives the friction wheel 310 to reverse through the one-way bearing to actively rub the fabric, thereby simulating the state of the fabric when it rubs against the convex strip during actual washing, and thus evaluating the friction performance of the fabric in this state; this method accelerates the friction of the fabric.

[0025] It should be noted that, in order to ensure the stability of the mounting post 25 during the test, two sets of clamps 251 can be fixedly installed on the disc 27 to clamp and restrict the mounting post 25 pressed on the fabric, so as to prevent the mounting post 25 from shaking due to the action of the protrusion 43 when the friction wheel 310 rotates actively. The clamp 251 is an existing pneumatic finger, which will not be described in detail in this embodiment.

[0026] Of course, in some embodiments, the power motor may not be connected to the friction wheel 310 through a one-way bearing, and may directly drive the friction wheel 310 to rotate. During the test, the servo motor 39 is not started, the rotating block 32 is kept stationary, and the friction wheel 310 is driven to rotate by the power motor, thereby performing a fixed-point friction test on the fabric.

[0027] Furthermore, an inlet pipe 41 and an outlet pipe 42 are respectively provided on the cylinder 271, and a water supply device and a water pumping device are installed inside the equipment box 23. The water supply device and the water pumping device can be connected through quick-release connectors and the inlet pipe 41 and the outlet pipe 42. After the fabric is pressed by the cylinder 271, a certain amount of water can be injected into the inside of the cylinder 271 through the water supply equipment, so that the fabric changes from a dry state to a wet state, in order to simulate the abrasion resistance of the fabric when it is wet during washing. After a certain period of time, the water inside the cylinder 271 is pumped out by the pumping equipment and the outlet pipe 42 to prevent excessive water flow from splashing everywhere under centrifugal force during subsequent tests. After the water is pumped out, the water supply equipment and the pumping equipment are disconnected from the inlet pipe 41 and the outlet pipe 42. like Figure 5As shown, a protective sleeve 3 adapted to the outer circumference of the cylinder 271 is also provided on the circular seat 301. Thus, after the cylinder 271 presses the fabric, the protective sleeve 3 protects the seal between the cylinder 271 and the circular seat 301, preventing water in the wet fabric from overflowing and splashing everywhere under the action of centrifugal force.

[0028] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
