Description

Technical Field

[0001] The present invention mainly relates to the technical field of decorative board testing, and particularly relates to a scratch resistance testing device for scratch-resistant decorative boards. Background Art

[0002] A scratch-resistant decorative board is a decorative material with high scratch resistance. With its excellent scratch resistance, it can easily resist scratches from sharp objects in daily life, ensuring the lasting perfection of the decorative surface. This characteristic not only virtually extends the service life of the decorative material but also greatly reduces the cost incurred by frequent replacement and additional maintenance. Therefore, scratch-resistant decorative boards have shown extensive application value in various occasions that need to cope with the challenges of daily wear and scratches.

[0003] In order to ensure that the scratch-resistant decorative board has excellent scratch resistance, its scratch resistance characteristics must be strictly tested before leaving the factory. However, the current technical method, which only relies on sliding a scratch knife on the surface of the scratch-resistant decorative board for testing, has obvious limitations because it cannot precisely control the magnitude of the force exerted by the scratch knife. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a scratch resistance testing device for scratch-resistant decorative boards.

[0005] The technical solution adopted to solve the above technical problem is: a scratch resistance testing device for scratch-resistant decorative boards, including a sliding frame. Above the sliding frame, there is a first motor. A first gear is connected to the rotating shaft of the first motor. Above the sliding frame and on the side of the first gear, there is a toothed disc, and the first gear meshes with the toothed disc. Above the toothed disc, there is a driving block. On the sliding frame and above the toothed disc, two short guide rods are arranged in parallel. A guide seat is jointly arranged on the two short guide rods. On the guide seat, there is a measuring rod assembly. The measuring rod assembly includes a support rod. The support rod is slidably arranged on the guide seat. The bottom of the support rod is a round head that cooperates with the driving block, and the distance from the bottom round head of the support rod to the center of the toothed disc is equal to the distance from the driving block to the center of the toothed disc. A sealing cover is spirally arranged at the top of the support rod. A sliding piece is slidably arranged in the inner cavity of the sealing cover. A spring is connected between the support rod and the sliding piece. At the top of the sliding piece, there is a scratch knife for measuring the decorative board, and the scratch knife extends to the outside of the sealing cover.

[0006] Further, there are four driving blocks. The four driving blocks are sequentially and evenly arranged along the circumferential direction of the toothed disc, and the four driving blocks are in the shape of frustum of a cone with gradually increasing sizes.

[0007] Further, the short guide rods and the guide seat form a sliding fit. There are three groups of measuring rod assemblies. The support rods of the three groups of measuring rod assemblies are sequentially slidably arranged on the guide seat, and the tops of the scratch knives of the three groups of measuring rod assemblies gradually become thicker.

[0008] Further, a slide bar is connected to the guide seat, and the slide bar is slidably provided on the sliding frame. A toothed bar is provided on the slide bar, and a second gear is engaged below the toothed bar. A second motor is provided on the sliding frame, and the second gear is fixedly provided on the rotating shaft of the second motor.

[0009] Further, a frame is provided outside the sliding frame. Two middle guide bars are provided on the frame and below the sliding frame, and the sliding frame is slidably provided on the middle guide bars. A first lead screw is provided below the sliding frame, and the first lead screw is in threaded cooperation with the sliding frame. The first lead screw is connected to the rotating shaft of a third motor, and the third motor is fixedly provided on the sliding frame.

[0010] Further, a fourth motor is provided on the sliding frame. The rotating shaft of the fourth motor is connected to a second lead screw, and the second lead screw is rotatably provided on the sliding frame. Two long guide bars are symmetrically provided on both sides of the second lead screw on the sliding frame. A top displacement plate is slidably connected to the two long guide bars together. The middle of the top displacement plate is in threaded cooperation with the second lead screw. A suction cup for sucking the decorative board is provided below the top displacement plate.

[0011] Further, a rotary clamping cylinder for assisting in fixing the decorative board is provided below the top displacement plate.

[0012] Further, material storage components are provided on both sides of the frame. The material storage components include a moving frame. Hydraulic cylinders are vertically provided at the four corners above the moving frame. The end parts of the telescopic shafts of the hydraulic cylinders are commonly connected to a material placing plate for placing the decorative board.

[0013] Further, a photography mechanism for testing the decorative board is provided beside the sliding frame on the toothed bar.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: (1) In the present invention, when the driving block on the toothed disc moves to directly below the support rod, the driving block drives the support rod to move upward. The support rod drives the cover, the sliding piece, and the scratch knife to move upward. The scratch knife abuts against the lower part of the decorative board and stops moving, and the spring is compressed. Therefore, the spring provides elastic force to make the scratch knife act on the lower surface of the decorative board. Since the rising distance of the support rod is the height of the driving block, when the distance between the decorative board and the original position of the support rod is equal, the compression amount of the scratch knife can be determined, and thus the force of the scratch knife on the decorative board can be determined.

[0015] (2) In the present invention, the toothed disc drives the driving block to rotate, so that different driving blocks are directly below the support rod, that is, the support rod can rise to different heights, and the compression amount of the spring is also different accordingly. Therefore, the scratch knife has different acting forces on the decorative board, so as to test the scratch resistance of the decorative board under different pressures of the scratch knife.

[0016] (3) The starting motor two of the present invention is activated to drive the rotation of gear two. Gear two drives the sliding rod to translate on the sliding frame, and the sliding rod drives the guide seat to translate synchronously, so that the struts of different measuring rod assemblies are located directly above the driving block, thereby selecting different scratch knives to perform scratch tests on the decorative board.

Specific Embodiments

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Embodiment: AsFigures 1 to 9 As shown in the figure, a scratch-resistant test device for a scratch-resistant decorative board includes a sliding frame 1. Above the sliding frame 1, there is a first motor 2. A first gear 3 is connected to the rotating shaft of the first motor 2. Above the sliding frame 1 and on the side of the first gear 3, there is a toothed disc 4, and the first gear 3 meshes with the toothed disc 4. Above the toothed disc 4, there is a driving block 5.

[0029] On the sliding frame 1 and above the toothed disc 4, two short guide rods 6 are arranged in parallel. A guide seat 7 is provided on the two short guide rods 6. A measuring rod assembly is provided on the guide seat 7. The measuring rod assembly includes a support rod 8. The support rod 8 is slidably arranged on the guide seat 7. The bottom of the support rod 8 is a round head that cooperates with the driving block 5, and the distance from the center of the bottom round head of the support rod 8 to the center of the toothed disc 4 is equal to the distance from the driving block 5 to the center of the toothed disc 4. A cover 9 is spirally arranged at the top of the support rod 8. A sliding piece 10 is slidably arranged in the inner cavity of the cover 9. A spring 11 is connected between the support rod 8 and the sliding piece 10. A scratch knife 12 for measuring the decorative board 13 is provided at the top of the sliding piece 10, and the scratch knife 12 extends to the outside of the cover 9.

[0030] Specifically, place the decorative board 13 directly above the measuring rod assembly. Start the first motor 2. The first motor 2 drives the first gear 3 to rotate, thereby driving the toothed disc 4 to rotate. The driving block 5 on the toothed disc 4 moves to directly below the support rod 8. The driving block 5 drives the support rod 8 to move upward. The support rod 8 drives the cover 9, the sliding piece 10, and the scratch knife 12 to move upward. The scratch knife 12 abuts against the lower surface of the decorative board 13. The scratch knife 12 stops moving, and the spring 11 is compressed. Therefore, the spring 11 provides elastic force to make the scratch knife 12 act on the lower surface of the decorative board 13. Since the rising distance of the support rod 8 is the height of the driving block 5, when the original distance from the decorative board 13 to the support rod 8 is equal, the compression amount of the scratch knife 12 can be determined, and thus the magnitude of the force of the scratch knife 12 on the decorative board 13 can be determined.

[0031] Considering that it is necessary to test the scratch resistance performance of the decorative board 13 under different forces of the scratch knife 12, there are four driving blocks 5. The four driving blocks 5 are arranged in sequence and evenly along the circumferential direction of the toothed disc 4, and the four driving blocks 5 are in the shape of frustum of a cone with gradually increasing sizes, that is, the heights of the four driving blocks 5 are inconsistent. The toothed disc 4 drives the driving blocks 5 to rotate, so that different driving blocks 5 are directly below the support rod 8, that is, the support rod 8 can rise to different heights, and the compression amount of the spring 11 is also different. Therefore, the scratch knife 12 has different acting forces on the decorative board 13.

[0032] Considering that the tops of the scratch knives 12 are different, the degrees of scratching on the decorative board 13 are also inconsistent. The short guide rods 6 form a sliding fit with the guide seat 7. There are three groups of measuring rod assemblies. The support rods 8 of the three groups of measuring rod assemblies are sequentially slidably arranged on the guide seat 7, and the tops of the scratch knives 12 of the three groups of measuring rod assemblies gradually become thicker.

[0033] A slide bar 14 is connected to the guide base 7, and the slide bar 14 is slidably provided on the sliding frame 1. A toothed rod 15 is provided on the slide bar 14. Below the toothed rod 15, a second gear 16 is engaged. On the sliding frame 1, a second motor 17 is provided, and the second gear 16 is fixedly provided on the rotating shaft of the second motor 17.

[0034] Specifically, the second motor 17 provides driving force to drive the second gear 16 to rotate. The second gear 16 drives the slide bar 14 to translate on the sliding frame 1. The slide bar 14 drives the guide base 7 to translate synchronously, so that the support rods 8 of different measuring rod assemblies are located directly above the driving block 5, thereby selecting different scratch knives 12 to perform scratch tests on the decorative board 13.

[0035] Outside the sliding frame 1, there is a machine frame 18. On the machine frame 1 and below the sliding frame 1, there are two middle guide rods 19, and the sliding frame 1 is slidably provided on the middle guide rods 19. Below the sliding frame 1, there is a first lead screw 20, and the first lead screw 20 forms a threaded fit with the sliding frame 1. The first lead screw 20 is connected to the rotating shaft of the third motor 21, and the third motor 21 is fixedly provided on the sliding frame 1. Specifically, the third motor 21 drives the first lead screw 20 to rotate, thereby driving the sliding frame 1 to slide on the middle guide rods 19, and the sliding frame 1 drives the scratch knife 12 to move back and forth.

[0036] On the sliding frame 1, there is a fourth motor 22. The rotating shaft of the fourth motor 22 is connected to a second lead screw 23, and the second lead screw 23 is rotatably provided on the sliding frame 1. On the sliding frame 1 and symmetrically on both sides of the second lead screw 23, there are two long guide rods 24. A top displacement plate 25 is slidably connected to the two long guide rods 24 together. The middle part of the top displacement plate 25 forms a threaded fit with the second lead screw 23. Below the top displacement plate 25, there is a suction cup 26 for sucking the decorative board 13. Specifically, the fourth motor 22 provides driving force to drive the second lead screw 23 to rotate, thereby driving the top displacement plate 25 to slide along the long guide rods 24, so as to drive the decorative board 13 to move left and right.

[0037] Through the combination of the forward and backward movement of the scratch knife 12 and the left and right movement of the decorative board 13, the scratch knife 12 performs scratch tests on the decorative board 13 in multiple directions.

[0038] Below the top displacement plate 25, there is a rotary clamping cylinder 27 for assisting in fixing the decorative board 13. When the telescopic shaft of the rotary clamping cylinder 27 contracts, the telescopic shaft of the rotary clamping cylinder 27 rotates synchronously. The pressing plate at the end of the telescopic shaft of the rotary clamping cylinder 27 presses the decorative board 13, making the decorative board 13 more stable during the test.

[0039] Material storage components are provided on both sides of the frame 18, and the material storage components include a moving frame 28. The bottom of the moving frame 28 is provided with rollers for easy movement. Hydraulic cylinders 29 are vertically provided at the four corners above the moving frame 28. The ends of the telescopic shafts of the hydraulic cylinders 29 are commonly connected to a material placement plate 30. The material placement plate 30 is used to place the decorative panel 13. Specifically, the two material storage components are moved to the bottom of the screw rod 23, so that the top moving plate 25 moves to the top of the material storage component for loading materials, and at the same time, the hydraulic cylinder 29 of the material storage component for loading materials is started to make the decorative panel 13 on the material placement plate 30 rise to contact with the suction cup 26, and the suction cup 26 absorbs the decorative panel 13; after the test of the decorative panel 13 is completed, the top moving plate 25 is moved to the top of the material storage component for unloading materials, and the suction cup 26 releases the screw rod 23 on the material placement plate 30 of the material storage component for unloading materials.

[0040] A photographic mechanism 31 for testing the decorative panel 13 is provided on the gear rod 15 and located beside the sliding frame 1. When the decorative panel 13 after the test passes through the photographic mechanism 31, the photographic mechanism 31 determines the degree of scratches on the decorative panel 13, thereby determining the scratch resistance performance of the decorative panel 13.

[0041] Working principle: move the two material storage components to the bottom of the screw rod 23, so that the top moving plate 25 moves to the top of the loading material storage component, and at the same time start the hydraulic cylinder 29 of the loading material storage component to make the decorative plate 13 on the material placement plate 30 rise to contact with the suction cup 26, the suction cup 26 sucks the decorative plate 13, the telescopic shaft of the rotary clamping cylinder 27 contracts, the telescopic shaft of the rotary clamping cylinder 27 rotates synchronously, and the pressure plate on the end of the telescopic shaft of the rotary clamping cylinder 27 presses the decorative plate 13, so that the decorative plate 13 is more stable during the test.

[0042] Start the motor 4 22, drive the screw rod 2 23 to rotate, thereby driving the top moving plate 25 to slide along the long guide rod 24, so that the top moving plate 25 moves to the top of the sliding frame 1, start the motor 1 2, the motor 1 2 drives the gear 1 3 to rotate, thereby driving the toothed disc 4 to rotate, the drive block 5 on the toothed disc 4 moves to the bottom of the support rod 8, the drive block 5 drives the support rod 8 to move upward, the support rod 8 drives the cover 9, the slide 10 and the scoring knife 12 to move upward, the scoring knife 12 supports the bottom of the decorative plate 13, the scoring knife 12 no longer moves, the spring 11 is compressed, so the spring 11 provides elastic force to make the scoring knife 12 act on the lower surface of the decorative plate 13. Since the rising distance of the support rod 8 is the height of the drive block 5, when the original distance from the decorative plate 13 to the support rod 8 is equal, the compression amount of the scoring knife 12 can be determined, so the force of the scoring knife 12 on the decorative plate 13 can be determined.

[0043] Restart the fourth motor 22 again to move the decorative panel 13 on the top displacement plate 25 left and right; at the same time, start the third motor 21, and the third motor 21 drives the first lead screw 20 to rotate, thereby driving the sliding frame 1 to slide on the middle guide rod 19, and the sliding frame 1 drives the scratch knife 12 to move back and forth; through the combination of the back-and-forth movement of the scratch knife 12 and the left-and-right movement of the decorative panel 13, the scratch knife 12 performs scratch tests on the decorative panel 13 in multiple directions.

[0044] During the test, if it is necessary to test the scratch resistance of the decorative panel 13 under different forces of the scratch knife 12, start the first motor 2, the gear disk 4 drives the driving block 5 to rotate, so that different driving blocks 5 are directly below the support rod 8, that is, the support rod 8 can be raised to different heights, and the compression amount of the spring 11 is also different accordingly. Therefore, the scratch knife 12 has different acting forces on the decorative panel 13, so as to test the scratch resistance of the decorative panel 13 under different pressures; during the test, if it is necessary to test the scratch resistance of the decorative panel 13 under the action of different scratch knives 12, start the second motor 17, drive the second gear 16 to rotate, the second gear 16 drives the slide rod 14 to translate on the sliding frame 1, and the slide rod 14 drives the guide seat 7 to translate synchronously, so that the support rods 8 of different measuring rod assemblies are directly above the driving block 5, thereby selecting different scratch knives 12 to perform scratch tests on the decorative panel 13.

[0045] After the scratch knife 12 finishes the scratch test on the decorative panel 13, restart the fourth motor 22 again to make the tested decorative panel 13 pass through the photography mechanism 31. The photography mechanism 31 judges the scratch degree of the decorative panel 13, so as to judge the scratch resistance performance of the decorative panel 13.

[0046] Finally, after the decorative panel 13 finishes the test, move the top displacement plate 25 to directly above the blanking bin assembly, extend the telescopic shaft of the rotary clamping cylinder 27, separate the pressing plate on the end of the telescopic shaft of the rotary clamping cylinder 27 from the decorative panel 13, and the suction cup 26 releases the second lead screw 23 on the placement plate 30 of the blanking bin assembly.

[0047] Repeat the above process to complete the batch test of the decorative panel 13.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
