Description

Technical Field

[0001] This invention relates to the field of abrasion resistance testing technology, specifically to a carpet anti-slip backing performance simulation testing device and its usage method. Background Technology

[0002] The anti-slip backing of a carpet prevents it from sliding, ensuring safety, and also improves comfort and durability. Because carpets are subjected to pressure for a long time, there is also constant relative friction between the anti-slip backing and the ground, so the durability of the anti-slip backing is very important.

[0003] For example, Chinese patent CN118706657B discloses a high-efficiency Martindale abrasion tester, which includes a machine base, a turntable mechanism, an evaluation table, and a main control module. The turntable mechanism is equipped with test modules, and each test module includes a counterweight device, a weighing module, a driver, a friction cloth clamp, and a sample clamp. The machine base is equipped with loading and unloading stations, a working station, and an evaluation station. When the test module that has completed the test enters the loading and unloading station, the sample that has completed the abrasion test is taken out and the friction cloth is replaced without affecting the work of other test modules in the working station. However, this device and the prior art still have the following technical problems. The replacement of samples relies on manual operation. When facing continuous testing of batches of samples, the manual labor intensity is high and the efficiency of manual sample replacement is low. Furthermore, when fixing the sample, it is necessary to lay the sample flat and wrinkle-free on the sample fixture base. Manual operation also makes it difficult to ensure the consistency of sample fixing, which affects the accuracy of test results.

[0004] Based on this, the present invention designs a carpet anti-slip backing performance simulation test device and its usage method to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a carpet anti-slip backing performance simulation test device and its usage method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A carpet anti-slip backing performance simulation testing device includes a base and a drive plate; A rotating platform is rotatably mounted on the base, and multiple sets of anti-wrinkle sample fixing mechanisms are equidistantly installed in a circular array along the outer edge of the rotating platform. The anti-wrinkle sample fixing mechanism includes a sample tray, a ring pressure plate, two wing blocks, a multi-stage smoothing and pressing edge assembly, and two one-way closing assemblies. The sample tray is fixed to the rotating table, and the ring pressure plate is inserted into the upper side of the sample tray. The upper end of the sample tray and the lower end of the ring pressure plate are provided with matching stepped structures. The two wing blocks are symmetrically fixed to the left and right sides of the ring pressure plate. The multi-stage smoothing and pressing edge assembly is installed inside the ring pressure plate, and the two one-way closing assemblies are respectively installed between the two wing blocks and the ring pressure plate. The drive plate is mounted on the rotary table and can move along a preset trajectory. Multiple sets of abrasive fixing mechanisms, which correspond one-to-one with the anti-wrinkle sample fixing mechanism, are installed in a circumferential array along the outer edge of the drive plate. The bracket is fixed to the machine base and located on the front side of the rotary table. An automatic sample loading and unloading mechanism is installed between the bracket and the machine base. A vision module is also fixed to the bracket. The machine base is also equipped with a sample fixing control mechanism, which includes a pressure plate control component mounted on the machine base and a mold lifting component mounted on the bracket.

[0007] Furthermore, the multi-stage smoothing and pressing assembly includes multiple upper pressing assemblies, multiple lower pressing assemblies, and multiple top pressing blocks. Multiple receiving slots are equidistantly arranged in a circular array on the inner side of the ring pressing plate. The multiple upper pressing assemblies and multiple lower pressing assemblies are respectively installed in the receiving slots in a circular array, and the upper pressing assemblies and lower pressing assemblies are staggered. The top of the ring pressing plate between adjacent upper pressing assemblies and lower pressing assemblies is fixedly connected to the top pressing block.

[0008] Furthermore, the upper pressing assembly includes a pressing shaft, a connecting block, and a floating assembly. The connecting block is mounted on the inner wall of the receiving groove via the floating assembly, enabling the connecting block to move radially along the ring pressing plate. The pressing shaft is rotatably connected to the connecting block. The upper and lower pressing components have the same structure, but the pressing axis of the upper pressing component is higher than that of the lower pressing component.

[0009] Furthermore, the one-way closing assembly includes a ratchet rack, a ratchet pawl, and a connecting plate. The ratchet rack is fixed to the side of the sample pan, one end of the ratchet pawl engages with the ratchet rack, and the other end of the ratchet pawl is fixed to the connecting plate. The connection between the ratchet pawl and the connecting plate is hinged to the lower end of the wing block via a pivot. A torsion spring is fixed between the pivot and the ratchet rack, so that the ratchet pawl always tends to engage with the ratchet rack.

[0010] Furthermore, the abrasive fixing mechanism includes a counterweight, a pressure rod, an abrasive disc, a limiting sleeve, and a convex ring. The limiting sleeve is fixedly connected to the extension end of the drive plate, and the pressure rod is slidably connected to the limiting sleeve. The lower end of the pressure rod is detachably connected to the abrasive disc. The upper end of the pressure rod is inserted into the counterweight. The convex ring is fixedly connected to the pressure rod and located between the counterweight and the limiting sleeve. By replacing different counterweights, different frictional forces can be applied to the sample by the abrasive.

[0011] Furthermore, the grinding tool lifting assembly includes a transverse push cylinder, a first lifting push cylinder, and a lifting block. The first lifting push cylinder is fixed to the upper end of the bracket, the transverse push cylinder is fixed to the output end of the first lifting push cylinder, and the lifting block is fixed to the output end of the transverse push cylinder. The end of the lifting block is provided with a "U"-shaped groove that cooperates with the pressure rod.

[0012] Furthermore, the pressure plate control assembly includes two insert blocks, two positioning blocks, two locking components, two lifting arms, two first lifting linear modules, and a first translation linear module. The first translation linear modules are fixedly connected to the base, and the two first lifting linear modules are symmetrically fixedly connected to the left and right sides of the moving end of the first translation linear module. The lifting arms are fixedly connected to the moving end of the first lifting linear module, and the insert blocks are fixedly connected to the extension end of the lifting arms. The insert blocks are inserted into the wing blocks, and positioning blocks are fixedly connected to the insert blocks. Locking components are also installed between the insert blocks and the wing blocks.

[0013] Furthermore, the pressure plate control assembly also includes two levers, which are respectively installed at the lower ends of the two inserts. The end of the lever near the rotary table is provided with a guide slope. The lever is used to push the connecting plate to disengage the ratchet pawl from the ratchet rack.

[0014] Furthermore, the automatic sample loading and unloading mechanism includes a feeding component, a receiving component, and a transferring component. The feeding component and the receiving component are mounted on the machine base, and the transferring component is mounted on the bracket. The detection end of the vision module is aligned with the receiving component. The feeding component and the receiving component have the same structure.

[0015] To better achieve the objectives of this invention, the present invention also provides a method for using a carpet anti-slip backing performance simulation testing device, comprising the following steps: Step 1: The first translational linear module drives the insert block to move towards the ring pressure plate, so that the insert block and the wing block are inserted. At the same time, the pusher pushes the connecting plate to separate the ratchet pawl from the ratchet rack, releasing the lock between the sample plate and the ring pressure plate. Step 2: The first lifting linear module moves the insert block upward through the lifting arm, and the sample on the sample plate separates from the ring pressure plate under the pressure of the abrasive and stays on the sample plate. Step 3: The abrasive lifting assembly lifts the abrasive fixing mechanism from the sample tray; Step 4: The transfer assembly picks up the end of the sample on the sample tray that is close to the support and pulls the sample onto the sample tray. During the movement, the end of the sample that is not picked up hangs down naturally due to gravity, so that the sample can remain flat and wrinkle-free after being transferred to the receiving assembly. Step 5: Weigh the test sample using the receiving component and take a picture of the test sample using the vision module. Step 6: The transfer assembly grabs the end of the sample on the feeding assembly that is close to the rotating table and pulls the sample to the sample tray. During the movement, the end of the sample that is not grabbed hangs down naturally due to gravity, so that the sample can be transferred to the sample tray and remain flat and wrinkle-free. Step 7: The abrasive lifting assembly releases the abrasive fixing mechanism, allowing the abrasive fixing mechanism to reset and press the new sample onto the sample plate; Step 8: The pressure plate control component drives the ring pressure plate to press down and close with the sample plate; Step 9: The lower edge pressing assembly's pressing shaft first presses down on the edge of the sample. Through the cooperation of the connecting block and the floating assembly, the edge of the sample floats and presses against the side of the sample plate's step. The upper edge pressing assembly's pressing shaft then contacts the sample, pressing the edge of the sample between adjacent pressing shafts against the step of the sample plate. This prevents the sample between adjacent pressing shafts from arching and forming a bend due to pressure. Finally, the top pressing block presses and fixes the sample, and the ratchet rack and ratchet pawl cooperate to achieve the closed locking of the sample plate and the ring pressing plate, adapting to samples of different thicknesses. Step 10: The drive plate drives all abrasive fixing mechanisms to move according to the Lissajous figure, so that the abrasive causes uniform wear in all directions of the sample.

[0016] Compared with the prior art, the present invention has the following advantages: by cooperating with the mold lifting component, the pressure plate control component and the automatic sample loading and unloading mechanism, the sample can be automatically replaced. Under the action of the multi-stage smoothing and pressing component and the one-way closing component, the sample of different thicknesses can be flattened and fixed, which significantly reduces the intensity of manual labor, improves the testing efficiency of the sample, and is conducive to the standardization and continuous testing of the sample.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In some embodiments, please refer to the accompanying drawings. Figures 1-8 A carpet anti-slip backing performance simulation testing device, comprising a base 10; A rotating table 11 is rotatably mounted on the base 10, and multiple sets of anti-wrinkle sample fixing mechanisms 2 are equidistantly installed in a circular array along the outer edge of the rotating table 11. The base 10 has a built-in drive device (e.g., a motor-driven cam divider) that drives the rotary table 11 to rotate in steps. In some embodiments, the anti-wrinkle sample fixing mechanism 2 is provided with six sets, and the base 10 rotates 60 degrees per step.

[0022] The anti-wrinkle sample fixing mechanism 2 includes a sample tray 21, a ring pressing plate 22, two wing blocks 28, a multi-stage smoothing and pressing edge assembly, and two one-way closing assemblies. The sample tray 21 is fixedly connected to the rotating table 11, and the ring pressing plate 22 is inserted into the upper side of the sample tray 21. The upper end of the sample tray 21 and the lower end of the ring pressing plate 22 are provided with matching stepped structures. The two wing blocks 28 are symmetrically fixedly connected to the left and right sides of the ring pressing plate 22. The multi-stage smoothing and pressing edge assembly is installed inside the ring pressing plate 22, and the two one-way closing assemblies are symmetrically installed on both sides between the two wing blocks 28 and the ring pressing plate 22. The rotating table 11 is fixedly connected to a drive column 12 and a support column 13. The drive plate 14 is detachably connected to the upper ends of the drive column 12 and the support column 13. The drive column 12 is used to drive the drive plate 14 to move along a preset trajectory. Multiple sets of abrasive fixing mechanisms 3 corresponding to the anti-wrinkle sample fixing mechanism 2 are installed in a circular array along the outer edge of the drive plate 14. The bracket 4 is fixed to the base 10 and located in front of the rotary table 11. An automatic sample loading and unloading mechanism 6 is installed between the bracket 4 and the base 10. A vision module 5 is also fixed to the bracket 4. The vision module 5 is used to take pictures of the test sample after the test and keep them. The base 10 is also equipped with a sample fixing control mechanism 7. The sample fixing control mechanism 7 includes a pressure plate control component 72 installed on the base 10 and an abrasive lifting component 71 installed on the bracket 4. The abrasive lifting component 71 is used to lift the abrasive fixing mechanism 3 from the sample plate 21, and the pressure plate control component 72 is used to control the separation and opening of the sample plate 21 and the ring pressure plate 22.

[0023] In this invention, the drive column 12 and the support column 13 work together to control the movement of the drive plate 14, thereby causing all abrasive fixing mechanisms 3 to move according to the Lissajous figure, so that the abrasive causes uniform wear in all directions of the sample. After a round of testing is completed, the pressure plate control component 72 controls the ring pressure plate 22 to lift up and separate from the sample plate 21. The sample on the sample plate 21 is separated from the ring pressure plate 22 under the pressure of the abrasive fixing mechanism 3 and stays on the sample plate 21. The abrasive lifting component 71 then lifts the abrasive fixing mechanism 3 from the sample plate 21. The sample on the sample plate 21 is replaced by the sample automatic loading and unloading mechanism 6, and the vision module 5 takes pictures of the tested sample for storage. Subsequently, the abrasive lifting assembly 71 releases the abrasive fixing mechanism 3, causing the abrasive fixing mechanism 3 to reset and press the new sample onto the sample plate 21. The pressure plate control assembly 72 then drives the ring pressure plate 22 to press down and close with the sample plate 21. During the closing process, the multi-stage smoothing and pressing edge assembly flattens and fixes the sample onto the sample plate 21, and the one-way closing assembly adapts to locking samples of different thicknesses. In this invention, the automatic sample loading and unloading mechanism 6, in conjunction with the mold lifting component 71, the pressure plate control component 72, and the sample loading and unloading mechanism 6, can realize the automatic replacement of the sample. Under the action of the multi-stage smoothing and pressing component and the one-way closing component, the sample of different thicknesses can be flattened and fixed, which significantly reduces the intensity of manual labor, improves the testing efficiency of the sample, and is conducive to the standardization and continuous testing of the sample.

[0024] like Figure 6 and Figure 7 As shown, the multi-stage smoothing and pressing assembly includes multiple upper pressing assemblies, multiple lower pressing assemblies, and multiple top pressing blocks 24. Multiple receiving slots 23 are equidistantly arranged in a circular array on the inner side of the annular pressing plate 22. The multiple upper pressing assemblies and multiple lower pressing assemblies are respectively installed in a circular array within each receiving slot 23, and the upper pressing assemblies and lower pressing assemblies are staggered. The top of the annular pressing plate 22 between adjacent upper and lower pressing assemblies is fixedly connected to the top pressing block 24. The upper pressing assembly includes a pressing shaft 25, a connecting block 26, and a floating assembly 27. The connecting block 26 is mounted on the inner wall of the receiving groove 23 via the floating assembly 27, allowing the connecting block 26 to move radially along the ring pressing plate 22. The pressing shaft 25 is rotatably connected to the connecting block 26. The upper and lower pressing components have the same structure, but the pressing shaft 25 of the upper pressing component is higher than that of the lower pressing component.

[0025] The one-way closing assembly includes a ratchet rack 29, a ratchet pawl 210, and a connecting plate 211. The ratchet rack 29 is fixed to the side of the sample pan 21. One end of the ratchet pawl 210 is engaged with the ratchet rack 29, and the other end of the ratchet pawl 210 is fixed to the connecting plate 211. The connection between the ratchet pawl 210 and the connecting plate 211 is hinged to the lower end of the wing block 28 via a pivot. A torsion spring is fixed between the pivot and the ratchet rack 29, so that the ratchet pawl 210 always tends to engage with the ratchet rack 29.

[0026] In this invention, after the sample tray 21 and the ring pressing plate 22 are separated, the automatic sample loading and unloading mechanism 6 places a new sample on the sample tray 21. Then, the ring pressing plate 22 moves down, and the pressing shaft 25 of the lower pressing component first presses down on the edge of the sample. Through the cooperation of the connecting block 26 and the floating component 27, the edge of the sample is floated and pressed against the stepped side of the sample tray 21. The pressing shaft 25 of the upper pressing component then contacts the sample, pressing the edge of the sample between adjacent pressing shafts 25 against the step of the sample tray 21 to avoid the sample between adjacent pressing shafts 25 from arching and forming a bend due to being pressed. Finally, the top pressing block 24 presses and fixes the sample, and the ratchet 29 and ratchet pawl 210 cooperate to achieve the closed locking of the sample tray 21 and the ring pressing plate 22.

[0027] like Figure 4 and Figure 5 As shown, the abrasive fixing mechanism 3 includes a counterweight 31, a pressure rod 32, an abrasive disc 33, a limiting sleeve 34, and a convex ring 35. The limiting sleeve 34 is fixedly connected to the extension end of the drive plate 14. The pressure rod 32 is slidably connected to the limiting sleeve 34. The lower end of the pressure rod 32 is inserted into the abrasive disc 33. The abrasive disc 33 is used to install the abrasive, and fasteners (such as bolts) are provided on the abrasive disc 33 to fix the pressure rod 32 and the abrasive disc 33 relatively. The upper end of the pressure rod 32 is inserted into the counterweight 31. The convex ring 35 is fixedly connected to the pressure rod 32 and located between the counterweight 31 and the limiting sleeve 34. By replacing different counterweights 31, different frictional forces can be applied to the sample by the abrasive.

[0028] like Figure 8 As shown, the grinding tool lifting assembly 71 includes a transverse push cylinder 711, a first lifting push cylinder 712, and a lifting block 713. The first lifting push cylinder 712 is fixed to the upper end of the bracket 4, the transverse push cylinder 711 is fixed to the output end of the first lifting push cylinder 712, and the lifting block 713 is fixed to the output end of the transverse push cylinder 711. The end of the lifting block 713 is provided with a "U" shaped groove that cooperates with the pressure rod 32.

[0029] like Figure 4 and Figure 9 As shown, the pressure plate control assembly 72 includes two insert blocks 721, two positioning blocks 722, two locking components 723, two lifting arms 724, two first lifting linear modules 725, and a first translational linear module 726. The first translational linear module 726 is fixedly connected to the base 10, and the two first lifting linear modules 725 are symmetrically fixedly connected to the left and right sides of the moving end of the first translational linear module 726. The lifting arms 724 are fixedly connected to the moving end of the first lifting linear module 725, and the insert blocks 721 are fixedly connected to the extension end of the lifting arms 724. The insert blocks 721 are inserted into the wing blocks 28, and the positioning blocks 722 are fixedly connected to the insert blocks 721. A locking component 723 is also installed between the insert blocks 721 and the wing blocks 28. The pressure plate control assembly 72 also includes two levers 727, which are respectively installed at the lower ends of the two inserts 721. The levers 727 have a guide slope at the end near the rotary table 11. The levers 727 are used to push the connecting plate 211 to disengage the ratchet pawl 210 from the ratchet rack 29.

[0030] In this embodiment, a pressure sensor is fixedly connected between the moving end of the first lifting linear module 725 and the lifting arm 724. In this embodiment, the locking component 723 includes an electromagnetic push rod and a socket. The wing block 28 has a socket, and the electromagnet is fixed to the plug block 721. The output end of the electromagnet is plugged into the socket.

[0031] In this invention, when the sample needs to be replaced, the first translational linear module 726 first drives the insert block 721 towards the ring pressure plate 22, so that the insert block 721 and the wing block 28 are inserted. The positioning block 722 positions the wing block 28, and the locking component 723 fixes the insert block 721 and the positioning block 722 relative to each other. During the insertion process, the pusher block 727 pushes the connecting plate 211 downward to rotate, so that the ratchet pawl 210 separates from the ratchet rack 29, releasing the lock between the sample plate 21 and the ring pressure plate 22. The first lifting linear module 725 drives the insert block 721 upward through the lifting arm 724, thereby driving the ring pressure plate 22 upward away from the sample plate 21 to release the sample. Then, the transverse push cylinder 711 drives the lifting block 713 to move towards the pressure rod 32, so that the lifting block 713 and the pressure rod 32 are aligned. Then, the first lifting push cylinder 712 drives the lifting block 713 to move upward. The lifting block 713 and the convex ring 35 cooperate to move the pressure rod 32 upward, thereby moving the abrasive disk 33 upward and separating it from the sample, so that the sample remains on the upper surface of the sample disk 21. After the sample is replaced, the abrasive disk 33 is first reset and moved down to press the sample onto the upper surface of the sample disk 21. Then, the ring pressure disk 22 is reset and moved down to close with the sample disk 21 again, thus fixing the sample. The locking component 723 releases the locking effect between the insert block 721 and the wing block 28. The insert block 721 is pulled off the wing block 28. Before the insert block 721 is completely separated from the wing block 28, the pusher block 727 has already disengaged from the connecting plate 211, so that the ratchet pawl 210 re-engages with the ratchet rack 29, restoring the locking effect of closing the sample disk 21 and the ring pressure disk 22.

[0032] like Figure 2 and Figure 8As shown, the automatic sample loading and unloading mechanism 6 includes a feeding component 61, a receiving component 62, and a transferring component 63. The feeding component 61 and the receiving component 62 are mounted on the base 10, and the transferring component 63 is mounted on the bracket 4. The detection end of the vision module 5 is aligned with the receiving component 62. The feeding component 61 and the receiving component 62 have the same structure. The feeding assembly 61 includes multiple limiting rods 611, a second lifting linear module 612, a weighing device 613, and a support plate 614. The second lifting linear module 612 is fixedly connected to the base 10, the weighing device 613 is fixedly connected to the moving end of the second lifting linear module 612, and the support plate 614 is fixedly connected to the upper end of the weighing device 613. The multiple limiting rods 611 are fixedly connected to the base 10 and are arranged in a circumferential array on the side of the support plate 614. The material transfer assembly 63 includes a second translational linear module 631, a second lifting cylinder 632, a connecting arm 633, and two vacuum suction cups 634. The second translational linear module 631 is fixed to the bracket 4, the second lifting cylinder 632 is fixed to the moving end of the second translational linear module 631, the connecting arm 633 is fixed to the moving end of the second lifting cylinder 632, and the two vacuum suction cups 634 are symmetrically fixed to the left and right sides of the extension end of the connecting arm 633. In this invention, when loading the sample, the second lifting cylinder 632 drives the vacuum suction cup 634 to grab the end of the sample near the rotating table 11, and the second translational linear module 631 then moves the sample to the sample tray 21, thereby pulling the sample onto the sample tray 21. During the loading process, the sample's own drooping ensures that the sample remains flat when moved onto the sample tray 21. During the unloading process, the vacuum suction cup 634 grabs the end of the sample near the support 4, pulling the sample onto the support plate 614 of the transfer assembly 63 and keeping it flat, which is then photographed and recorded by the vision module 5. The second lifting linear module 612 controls the vertical movement of the weighing device 613 and the support plate 614, enabling the sample to be loaded and unloaded to remain at a preset height and preset position, facilitating grabbing and photographing.

[0033] In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, a method for using a carpet anti-slip backing performance simulation testing device includes the following steps: Step 1: The first translational linear module 726 drives the insert block 721 to move towards the ring pressure plate 22, so that the insert block 721 and the wing block 28 are inserted. At the same time, the pusher block 727 pushes the connecting plate 211 to separate the ratchet pawl 210 from the ratchet rack 29, thereby releasing the lock between the sample plate 21 and the ring pressure plate 22. Step 2: The first lifting linear module 725 drives the insert block 721 to move upward through the lifting arm 724. The sample on the sample plate 21 is separated from the ring pressure plate 22 under the pressure of the abrasive and stays on the sample plate 21. Step 3: The abrasive lifting assembly 71 lifts the abrasive fixing mechanism 3 from the sample tray 21; Step 4: The transfer component 63 grabs the end of the sample on the sample tray 21 that is close to the support 4 and pulls the sample to the sample tray 21. During the movement, the end of the sample that is not grabbed hangs down naturally due to gravity, so that the sample can remain flat and wrinkle-free after being transferred to the receiving component 62. Step 5: Weigh the test sample using the weighing device 613 and take a picture of the test sample using the vision module 5 for record-keeping. Step 6: The transfer component 63 grabs the end of the sample on the feeding component 61 that is close to the rotating table 11 and pulls the sample to the sample tray 21. During the movement, the end of the sample that is not grabbed hangs down naturally under gravity, so that the sample can be transferred to the sample tray 21 and remain flat and wrinkle-free. Step 7: The abrasive lifting assembly 71 releases the abrasive fixing mechanism 3, allowing the abrasive fixing mechanism 3 to reset and press the new sample onto the sample plate 21; Step 8: The pressure plate control component 72 drives the ring pressure plate 22 to press down and close with the sample plate 21; Step 9: The pressing shaft 25 of the lower pressing assembly first presses down on the edge of the sample. Through the cooperation of the connecting block 26 and the floating assembly 27, the edge of the sample is floated and pressed against the stepped side of the sample plate 21. The pressing shaft 25 of the upper pressing assembly then contacts the sample, pressing the edge of the sample between adjacent pressing shafts 25 against the step of the sample plate 21 to avoid the sample between adjacent pressing shafts 25 from arching and forming a bend due to being pressed. Finally, the top pressing block 24 presses and fixes the sample, and the ratchet 29 and ratchet pawl 210 cooperate to achieve the closed locking of the sample plate 21 and the ring pressing plate 22, which can adapt to samples of different thicknesses. Step 10: Drive plate 14 drives all abrasive fixing mechanisms 3 to move according to the Liszt graph, so that the abrasive causes uniform wear in all directions of the sample.

[0034] In this invention, the automatic replacement of the sample can be achieved through the cooperation of various components, and the flatness and fixation effect of samples of different thicknesses can be achieved under the action of multi-level smoothing and pressing components and one-way closing components. The weight of the sample after testing can be weighed by the weighing device 613, and the sample after testing can be photographed and stored by the vision module 5. The manual only needs to place the samples to be tested in sequence, which significantly reduces the labor intensity of manual labor, improves the testing efficiency of the samples, and is conducive to the standardization and continuous testing of the samples.

A method of use, utilizing the carpet anti-slip backing performance simulation testing device according to claim 9, characterized in that, Includes the following steps: Step 1: The first translational linear module (726) drives the insert block (721) to move towards the ring pressure plate (22), so that the insert block (721) and the wing block (28) are inserted. At the same time, the pusher block (727) pushes the connecting plate (211) to separate the ratchet pawl (210) from the ratchet rack (29), thereby releasing the lock between the sample plate (21) and the ring pressure plate (22). Step 2: The first lifting linear module (725) drives the insert block (721) to move upward through the lifting arm (724). The sample on the sample plate (21) is separated from the ring pressure plate (22) under the pressure of the abrasive and stays on the sample plate (21). Step 3: The abrasive lifting assembly (71) lifts the abrasive fixing mechanism (3) from the sample plate (21); Step 4: The transfer component (63) grabs the end of the sample on the sample tray (21) that is close to the support (4) and pulls the sample to the sample tray (21).

During the movement, the end of the sample that is not grabbed hangs down naturally due to gravity, so that the sample can be transferred to the sample tray (21) and remain flat and wrinkle-free. Step 7: The abrasive lifting assembly (71) releases the abrasive fixing mechanism (3), allowing the abrasive fixing mechanism (3) to reset and press the new sample onto the sample plate (21); Step 8: The pressure plate control assembly (72) drives the ring pressure plate (22) to press down and close with the sample plate (21); Step 9: The pressing shaft (25) of the lower pressing assembly first presses down on the edge of the sample. Through the cooperation of the connecting block (26) and the floating assembly (27), the edge of the sample floats and presses against the side of the step of the sample plate (21). The pressing shaft (25) of the upper pressing assembly then contacts the sample, pressing the edge of the sample between adjacent pressing shafts (25) against the step of the sample plate (21) to avoid the sample between adjacent pressing shafts (25) from arching and forming a bend due to being pressed. Finally, the top pressing block (24) presses the sample tightly and fixes it.
