Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: an automotive decorative leather abrasion resistance testing device, including a machine base 1 and a frame 2 fixed on the machine base 1. The top of the machine base 1 is symmetrically provided with arc-shaped grooves 3, and a flattening component is provided in the arc-shaped grooves 3. The outer wall of the machine base 1 is provided with a drive component for driving the drive roller 4 to rotate. The frame 2 is provided with a lifting plate 8, and the bottom of the lifting plate 8 is provided with an abrasion resistance testing component, and the top of the lifting plate 8 is provided with a lifting component. The flattening assembly includes a drive roller 4, and drive rollers 4 are rotatably installed in the arc groove 3. Both ends of the drive roller 4 are provided with positive and negative threads. Both ends of the lifting plate 8 are equipped with C-shaped frames 10, and auxiliary fixing rollers 11 are rotatably installed in the C-shaped frames 10. The auxiliary fixing rollers 11 and drive rollers 4 cooperate with each other to fix and flatten the leather. Specifically, when it is necessary to fix the automotive trim leather, the two ends of the leather are placed on the two drive rollers 4 respectively. Then, the electric push rod 9 is activated to drive the lifting plate 8 and the C-shaped frame 10 to move down, which in turn drives the auxiliary fixing roller 11 to move down and press on the leather on top of the drive roller 4. At this time, the clamping force of the drive roller 4 and the auxiliary fixing roller 11 on the leather is just enough to flatten the leather without fixing it. Only after the leather is flattened, the drive roller 4 and the auxiliary fixing roller 11 clamp and fix the leather. Then the drive roller 4 rotates, and the positive and negative threads at both ends will drive the two ends of the leather to move in opposite directions. The rotation of the drive roller 4 realizes the automatic flattening and fixing of the leather, avoiding the tedious operation of manual flattening.

[0018] Furthermore, a positive and negative worm gear 5 is rotatably mounted on the outer side of the machine base 1, and both ends of the positive and negative worm gear 5 are meshed with worm wheels 6. Both worm wheels 6 are mounted on the ends of the drive roller 4. The positive and negative worm gear 5 is used to drive the two worm wheels 6 to rotate in opposite directions. A first motor 7 is fixedly mounted on the outer wall of the machine base 1, and the first motor 7 is used to drive the positive and negative worm gear 5 to rotate. Specifically, after the first motor 7 is started, the output shaft of the first motor 7 drives the positive and negative worm gears 5 to rotate. Since the threads at both ends of the positive and negative worm gears 5 are in opposite directions and mesh with two worm wheels 6 respectively, they will drive the two worm wheels 6 to rotate in opposite directions, thereby driving the two drive rollers 4 to rotate in opposite directions synchronously, ensuring that the two ends of the leather can be stretched evenly and improving the stability of the stretching effect.

[0019] Furthermore, the lifting assembly includes an electric push rod 9, which is vertically installed through the top of the frame 2, and a lifting plate 8 is installed at the output end of the electric push rod 9; Specifically, the electric push rod 9 can extend and retract after being powered on. The extension and retraction of its output end will drive the lifting plate 8 to move vertically within the frame 2, thereby adjusting the distance between the wear-resistant detection component at the bottom of the lifting plate 8 and the leather on the machine 1. This allows for flexible control of the contact pressure between the friction head 16 and the leather according to the thickness of the leather or the detection requirements.

[0020] Furthermore, guide rods 17 are vertically installed at both ends of the top of the lifting plate 8, and the top of the guide rods 17 slides through the frame 2; Specifically, when the lifting plate 8 moves up and down under the drive of the electric push rod 9, the guide rod 17 will slide synchronously along the through hole on the frame 2, playing a guiding and limiting role, effectively preventing the lifting plate 8 from tilting or shifting during the movement, and ensuring that the wear-resistant detection component can accurately align with the detection area of ​​the leather.

[0021] Furthermore, the wear resistance testing component includes a rectangular tube 12, a rectangular column 13, and a spring 14. The rectangular tube 12 is vertically installed at the bottom of the lifting plate 8, and the rectangular column 13 is slidably inserted into the bottom of the rectangular tube 12. The spring 14 is vertically installed at the top of the rectangular column 13, and the top of the spring 14 is fixedly installed inside the top of the rectangular tube 12. A second motor 15 is installed at the bottom of the rectangular column 13, and a friction head 16 is installed at the output end of the second motor 15. Specifically, during the abrasion resistance test, the rectangular column 13 can slide vertically inside the rectangular tube 12. The spring 14 is in a compressed state and applies a downward elastic force to the rectangular column 13, so that the friction head 16 is in close contact with the leather surface. After the second motor 15 is started, the second motor 15 drives the friction head 16 to rotate. The friction head 16 rubs against the leather surface to achieve the abrasion resistance test. The elastic force of the spring 14 can ensure the stability of the friction pressure and avoid the accuracy of the test results due to pressure fluctuations.

[0022] Furthermore, a guide column 18 is vertically installed on the outer wall of the rectangular column 13, and the top of the guide column 18 slides through the lifting plate 8, with limit blocks installed at the through end of the guide column 18. Specifically, the guide column 18 moves synchronously with the rectangular column 13. The part of the guide column 18 that passes through the lifting plate 8 can restrict the direction of movement of the rectangular column 13, prevent the rectangular column 13 from falling during the sliding process, and ensure the stability of the friction direction of the friction head 16. The limiting block can prevent the guide column 18 from disengaging from the lifting plate 8, thereby preventing the rectangular column 13 from sliding out of the rectangular tube 12, and playing a limiting protection role.

[0023] The workflow of this embodiment is as follows: First, the automotive trim leather to be tested is placed on top of the machine base 1, with both ends of the leather resting on the drive roller 4. Then, the electric push rod 9 is activated to move the lifting plate 8 and the C-shaped frame 10 downwards, thereby moving the auxiliary fixing roller 11 downwards and pressing it onto the leather on top of the drive roller 4. At this time, the clamping force of the drive roller 4 and the auxiliary fixing roller 11 on the leather is just enough to flatten the leather, without fixing it. Only after the leather is flattened is it clamped and fixed by the drive roller 4 and the auxiliary fixing roller 11. Then, the first motor 7 is activated. The drive roller 4 is driven to rotate in opposite directions by the forward and reverse worm gears 5 and worm wheel 6. Together with the auxiliary fixing roller 11, the leather is flattened and fixed. Then, the electric push rod 9 is controlled to move down a small area to fix the leather. During this process, the friction head 16 contacts the leather surface. At this time, the spring 14 is compressed and provides stable pressure. The second motor 15 is started, and the friction head 16 rotates to perform friction and abrasion resistance testing on the leather. After the test is completed, the second motor 15 is turned off, the electric push rod 9 is controlled to retract to raise the lifting plate 8, and then the first motor 7 is turned off. The tested leather can then be removed.
