Description

Technical Field

[0001] The present invention mainly relates to the technical field of decorative plate testing, and in particular to a scratch resistance testing device for scratch-resistant decorative plates. Background Art

[0002] Scratch-resistant decorative panels are highly scratch-resistant decorative materials. Their exceptional resistance to everyday scratches easily resists the effects of sharp objects, ensuring the long-lasting, flawless appearance of the decorative surface. This characteristic not only extends the lifespan of the decorative material but also significantly reduces the costs associated with frequent replacement and additional maintenance. Therefore, scratch-resistant decorative panels have demonstrated widespread application value in a wide range of applications requiring resistance to everyday wear and scratches.

[0003] To ensure that scratch-resistant decorative panels possess excellent scratch resistance, they must undergo rigorous scratch resistance testing before leaving the factory. However, the current method, which relies solely on sliding a scratch knife across the surface of the scratch-resistant decorative panel, has significant limitations because it cannot precisely control the force applied by the scratch knife. Summary of the Invention

The support rods of the three groups of measuring rod assemblies are slidably arranged on the guide seat in sequence, and the tops of the scratching knives of the three groups of measuring rod assemblies become thicker in sequence.

[0008] Furthermore, a sliding rod is connected to the guide seat, and the sliding rod is slidably arranged on the sliding frame. A gear rod is provided on the sliding rod, and a gear 2 is engaged below the gear rod. A motor 2 is provided on the sliding frame, and the gear 2 is fixed on the rotating shaft of the motor 2.

[0009] Furthermore, a frame is provided on the outside of the sliding frame, two middle guide rods are provided on the frame and below the sliding frame, and the sliding frame is slidably arranged on the middle guide rods, a screw rod 1 is provided below the sliding frame, and the screw rod 1 forms a threaded fit with the sliding frame, the screw rod 1 is connected to the rotating shaft of the motor 3, and the motor 3 is fixed on the sliding frame.

[0013] Furthermore, a photographic mechanism for testing the decorative panel is provided on the gear rod and located on the side of the sliding frame.

[0014] The beneficial effects of the present invention compared with the prior art are:

[0015] (1) The drive block on the toothed disc of the present invention moves to the position directly below the support rod.

The scoring knife stops moving and the spring is compressed. The spring provides elastic force to cause the scoring knife to act on the bottom surface of the decorative panel. Since the rising distance of the support rod is equal to the height of the drive block, when the distance between the decorative panel and the support rod is equal to the original distance, the amount of compression of the scoring knife can be determined, and therefore the force exerted by the scoring knife on the decorative panel can be determined.

[0016] (2) The toothed disc of the present invention drives the driving blocks to rotate, so that different driving blocks are located directly below the support rod, which can make the support rod rise to different heights. The compression amount of the spring is also different accordingly. Therefore, the scratching knife has different forces on the decorative plate, thereby testing the scratch resistance of the decorative plate under different pressures of the scratching knife.

[0017] (3) The present invention starts the second motor and drives the second gear to rotate. The second gear drives the slide bar to translate on the slide frame. The slide bar drives the guide seat to translate synchronously, so that the support rods of different measuring rod assemblies are located directly above the drive block, thereby selecting different scratch knives to perform scratch tests on the decorative panel.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Example: Figures 1 to 9 As shown, a scratch resistance testing device for scratch-resistant decorative panels includes a sliding frame 1, a motor 2 is provided above the sliding frame 1, a gear 3 is connected to the rotating shaft of the motor 2, a gear plate 4 is provided above the sliding frame 1 and on the side of the gear 3, and the gear 3 is engaged with the gear plate 4, and a drive block 5 is provided above the gear plate 4.

[0030] Two short guide rods 6 are provided in parallel on the sliding frame 1 and above the toothed disc 4. 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 strut 8, which is slidably provided on the guide seat 7. The bottom of the strut 8 is a round head that cooperates with the drive block 5, and the distance from the bottom round head of the strut 8 to the center of the toothed disc 4 is equal to the distance from the drive block 5 to the center of the toothed disc 4. A cover 9 is spirally provided on the top of the strut 8, and a slide 10 is slidably provided in the inner cavity of the cover 9. A spring 11 is connected between the strut 8 and the slide 10. A scratching knife 12 for measuring the decorative panel 13 is provided on the top of the slide 10, and the scratching knife 12 extends to the outside of the cover 9.

[0031] Specifically, decorative panel 13 is placed directly above the measuring rod assembly and motor 2 is started. This drives gear 3, which in turn drives toothed disc 4. Drive block 5 on toothed disc 4 moves to directly below strut 8. Drive block 5 drives strut 8 upward, which in turn drives cover 9, slide 10, and scoring blade 12 upward. Score blade 12 presses against the bottom of decorative panel 13, preventing it from moving. Spring 11 compresses, providing the force that forces score blade 12 to contact the bottom surface of decorative panel 13. Since the distance strut 8 rises equal to the height of drive block 5, when the distance between decorative panel 13 and strut 8 is equal to the original distance, the amount of compression of score blade 12 can be determined, and therefore the force exerted by score blade 12 on decorative panel 13 can be determined.

[0032] To test the scratch resistance of the decorative panel 13 under different forces applied by the scratching blade 12, four drive blocks 5 are provided. These blocks are evenly spaced along the circumference of the toothed disc 4 and are truncated cones of increasing size, meaning that the heights of the four blocks 5 are inconsistent. The toothed disc 4 rotates the drive blocks 5, positioning different blocks directly below the strut 8. This raises the strut 8 to different heights, resulting in varying compression of the spring 11. Consequently, the scratching blade 12 exerts varying forces on the decorative panel 13.

[0033] Taking into account that the tops of the scratching knives 12 are different and the degree of scratching on the decorative panel 13 is also inconsistent, the short guide rod 6 forms 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 slid on the guide seat 7 in turn, and the tops of the scratching knives 12 of the three groups of measuring rod assemblies become thicker in turn.

[0034] A slide rod 14 is connected to the guide seat 7, and the slide rod 14 is slidably arranged on the sliding frame 1. A gear rod 15 is provided on the slide rod 14, and a gear 2 16 is engaged below the gear rod 15. A motor 2 17 is provided on the sliding frame 1, and the gear 2 16 is fixed on the rotating shaft of the motor 2 17.

[0035] Specifically, motor 2 17 provides driving force to drive gear 2 16 to rotate, gear 2 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 rod 8 of different measuring rod assemblies is located directly above the drive block 5, thereby selecting different scratch knives 12 to perform scratch tests on the decorative panel 13.

[0036] A frame 18 is provided on the outside of the sliding frame 1, and two middle guide rods 19 are provided on the frame 18 and below the sliding frame 1, and the sliding frame 1 is slidably provided on the middle guide rod 19, and a screw rod 20 is provided below the sliding frame 1, and the screw rod 20 forms a threaded fit with the sliding frame 1, and the screw rod 20 is connected to the rotating shaft of the motor 3 21, and the motor 3 21 is fixed on the sliding frame 1. Specifically, the motor 3 21 drives the screw rod 20 to rotate, thereby driving the sliding frame 1 to slide on the middle guide rod 19, and the sliding frame 1 drives the scratching knife 12 to move back and forth.

[0037] A motor 4 22 is provided on the sliding frame 1, and a rotating shaft of the motor 4 22 is connected to a screw rod 23, and the screw rod 23 is rotatably provided on the sliding frame 1. Two long guide rods 24 are symmetrically provided on the sliding frame 1 and located on both sides of the screw rod 23. A top moving plate 25 is slidably connected to the long guide rods 24. The middle part of the top moving plate 25 forms a threaded fit with the screw rod 23, and a suction cup 26 for sucking the decorative panel 13 is provided under the top moving plate 25. Specifically, the motor 4 22 provides a driving force to drive the screw rod 23 to rotate, thereby driving the top moving plate 25 to slide along the long guide rod 24, thereby driving the decorative panel 13 to move left and right.

[0038] The scratching knife 12 performs scratch tests on the decorative panel 13 in multiple directions through a combination of forward and backward movement of the scratching knife 12 and left and right movement of the decorative panel 13 .

[0039] A rotary clamping cylinder 27 for assisting in fixing the decorative panel 13 is provided below the top moving plate 25. When 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 panel 13, making the decorative panel 13 more stable during testing.

[0040] 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 placing plate 30. The placing 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 loading material storage component, and at the same time, the hydraulic cylinder 29 of the loading material storage component is started to make the decorative panel 13 on the placing 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 unloading material storage component, and the suction cup 26 releases the screw rod 23 on the placing plate 30 of the unloading material storage component.

[0041] A photographic mechanism 31 for testing the decorative panel 13 is provided on the gear rod 15 and located on the side of the sliding frame 1. When the decorative panel 13 passes through the photographic mechanism 31 after the test, the photographic mechanism 31 determines the degree of scratches on the decorative panel 13, thereby determining the scratch resistance of the decorative panel 13.

[0042] 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 panel 13 on the material placement plate 30 rise to contact with the suction cup 26. The suction cup 26 absorbs the decorative panel 13, and 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 panel 13, making the decorative panel 13 more stable during the test.

[0043] Motor 4 22 is started, driving screw 2 23 to rotate, thereby driving top plate 25 to slide along long guide rod 24, causing top plate 25 to move directly above sliding frame 1. Motor 1 2 is started, driving gear 1 3 to rotate, thereby driving gear plate 4. Drive block 5 on gear plate 4 moves directly below support rod 8. Drive block 5 drives support rod 8 upward, which in turn drives cover 9, slide 10, and scoring knife 12 upward. Score knife 12 presses against the bottom of decorative panel 13, and then stops moving. Spring 11 is compressed, providing the elastic force that forces score knife 12 to act on the bottom surface of decorative panel 13. Since the height of support rod 8 is equal to the height of drive block 5, when the distance between decorative panel 13 and support rod 8 is equal to the original distance, the amount of compression of score knife 12 can be determined, and therefore the force exerted by score knife 12 on decorative panel 13 can be determined.

[0044] Start motor four 22 again to move the decorative panel 13 on the top moving plate 25 left and right; at the same time, start motor three 21, which drives screw rod one 20 to rotate, thereby driving the sliding frame 1 to slide on the middle guide rod 19, and the sliding frame 1 drives the scratching knife 12 to move back and forth; through the combination of the back and forth movement of the scratching knife 12 and the left and right movement of the decorative panel 13, the scratching knife 12 performs scratch tests on the decorative panel 13 in multiple directions.

[0045] During the test, if it is necessary to test the scratch resistance of the decorative plate 13 under different forces of the scratch knife 12, the motor 12 is started, and the gear disc 4 drives the drive block 5 to rotate, so that different drive 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. Therefore, the scratch knife 12 has different forces on the decorative plate 13, thereby testing the scratch resistance of the decorative plate 13 under different pressures of the scratch knife 12; during the test, if it is necessary to test the scratch resistance of the decorative plate 13 under the action of different scratch knives 12, the motor 2 17 is started, and the drive gear 2 16 is rotated. The gear 2 16 drives the slide bar 14 to translate on the sliding frame 1, and the slide bar 14 drives the guide seat 7 to translate synchronously, so that the support rod 8 of different measuring rod assemblies is located directly above the drive block 5, thereby selecting different scratch knives 12 to perform scratch tests on the decorative plate 13.

[0046] After the scratch knife 12 completes the scratch test on the decorative panel 13, the motor 22 is started again, so that the tested decorative panel 13 passes through the photographic mechanism 31, and 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.

[0047] Finally, after the test of the decorative panel 13 is completed, the top moving plate 25 is moved to the top of the material storage assembly for unloading, so that the telescopic shaft of the rotary clamping cylinder 27 is extended, and the pressure plate on the end of the telescopic shaft of the rotary clamping cylinder 27 is separated from the decorative panel 13, and the suction cup 26 releases the screw rod 23 onto the placing plate 30 of the material storage assembly for unloading.

[0048] By repeating the above process, batch testing of the decorative panels 13 can be completed.

[0049] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope of the present invention, which should be covered by the scope of protection of the present invention.
