[0001] The utility model relates to the field of PU artificial leather softness and hardness detection, in particular to a PU artificial leather softness and hardness detection device. Background Art

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used as a substitute for it. It is usually made from a fabric base coated with synthetic resin and various plastic additives. Artificial leather produced using PU resin as the raw material is called PU artificial leather. Usually, a layer of resin mixture is applied or laminated onto a fabric base, then heated to plasticize it, and rolled flat or embossed to obtain the product.

[0003] During the production process of existing artificial leather, it is often necessary to use hardness testing equipment to monitor the hardness of artificial leather products. However, when using the existing testing equipment, the artificial leather material is generally fixed to the testing table by four bolts. This fixing method requires manual rotation of the four bolts in sequence, which is not convenient for fixing and removing the leather. In addition, the leather is only fixed at the four corners by bolts, which has a poor fixing effect and is prone to leather displacement, affecting the testing effect. Summary of the Invention

[0007] Furthermore, the fixing assembly includes a U-shaped plate, a second electric push rod, a power plate, a fixed plate, a limit plate, a first rotating block, a pin shaft, a hinge block, a triangular plate, a second rotating block, a pressure claw, a fixed claw, a limit claw and a connecting frame. The bottom surface of the supporting base is symmetrically fixedly connected to the connecting frame, and the two connecting frames are symmetrically fixedly connected with the U-shaped plate. The inner wall surface of each U-shaped plate is symmetrically fixedly installed with the second electric push rod, the top end of the second electric push rod is fixedly connected to the power plate, the bottom surfaces of the two power plates are symmetrically fixedly connected with the fixed plates, and the two fixed plates are fixedly connected to the limit plates near their two ends, and there is a gap between each limit plate and the fixed plate. The first rotating block is symmetrically connected for rotation, and the surface of the first rotating block is rotatably connected to the hinge block through a pin shaft, and the hinge block is rotatably connected to the triangular plate at one end away from the first rotating block. The surface of the connecting frame is symmetrically fixedly connected to the limiting claw, and the triangular plate and the limiting claw are rotatably connected.

[0008] Furthermore, the four second electric push rods have the same specifications and strokes and are all controlled by the same control button, which facilitates the control of the four second electric push rods to operate synchronously and ensures smooth movement of the power plate.

[0009] Furthermore, four pressing claws are provided and are located on the surface of the supporting chassis near its four corners, so as to clamp and fix the artificial leather.

The upper serrations and the lower serrations are arranged crosswise with each other.

The fixing component includes a U-shaped plate 10, a second electric push rod 11, a power plate 12, a fixed plate 13, a limit plate 14, a first rotating block 15, a pin 16, a hinge block 17, a triangular plate 18, a second rotating block 19, a pressure claw 20, a fixed claw 22, a limit claw 23 and a connecting frame 29. The bottom surface of the supporting base frame 1 is symmetrically fixedly connected with the connecting frame 29, and the U-shaped plate 10 is symmetrically fixedly connected between the two connecting frames 29. The inner wall surface of each U-shaped plate 10 is symmetrically fixed with a second electric push rod 11, the top of the second electric push rod 11 is fixedly connected to a power plate 12, the bottom surfaces of the two power plates 12 are symmetrically fixedly connected to a fixed plate 13, and the two fixed plates 13 are fixedly connected to a limit plate 14 near their two ends. A first rotating block 15 is symmetrically rotatably connected between each limit plate 14 and the fixed plate 13, and the surface of the first rotating block 15 is rotatably connected to a hinge block 17 through a pin 16. The hinge block 17 is rotatably connected to a triangular plate 18 at one end away from the first rotating block 15. The surface of the connecting frame 29 is symmetrically fixedly connected to the limit claw 23, the triangular plate 18 and the limit claw 23 are rotatably connected, and the triangular plate 18 is rotatably connected to the second rotating block near one of its corners. 19.

Through the fixing assembly, the artificial leather can be clamped and fixed, which changes the traditional way of fixing the artificial leather by multiple bolts.

The surface of the supporting chassis 1 is located below each pressure plate 21 and is equipped with a placement block 26, which can increase the clamping area of ​​the artificial leather, thereby improving the fixation reliability of the artificial leather. The four second electric push rods 11 have the same specifications and strokes and are all controlled by the same control button, which is convenient for controlling the synchronous operation of the second electric push rods 11.The bottom surface of each placement block 26 is symmetrically fixed with a threaded column 24, the threaded column 24 is slidably connected to the support base 1, and the surface of the threaded column 24 is threadedly sleeved with an adjusting nut 25.

[0035] It should be noted that the electrical connection between the display screen 7 and the pressure sensor 9 is an existing mature technology.

[0036] When using this testing equipment to test the softness and hardness of artificial leather, first adjust the height of the placement block 26 according to the strength and thickness of the artificial leather. During adjustment, rotate the two adjusting nuts 25 on the surface of the threaded column 24 in turn so that the two adjusting nuts 25 move away from each other, then move the threaded column 24 and limit the threaded column 24 to a suitable position, then rotate the adjusting nuts 25 on the upper and lower sides so that the two adjusting nuts 25 approach each other until the position of the threaded column 24 can be fixed, and then repeat the above operation to adjust the positions of the other three placement blocks 26. By setting the threaded column 24 and the adjusting nuts 25, the distance between the placement block 26 and the pressing plate 21 can be adjusted according to the thickness of the artificial leather, so that leather of different thicknesses can be clamped and fixed. It has a wide range of applications and ensures that the four placement blocks 26 are at the same horizontal height. Then select artificial leather of appropriate length and lay the artificial leather on the surface of the four placement blocks 26. Then synchronously start the second electric push rod 11. The operation of the second electric push rod 11 can drive the power plate 12 to move upward. The force plate 12 moves up and then drives the fixed plate 13 and the limit plate 14 to move up. The limit plate 14 moves up and then can push the pin shaft 16 to move outward on the surface of the connecting frame 29. The pin shaft 16 moves and then drives the hinge block 17 to move. The limit claw 23 moves and then causes the triangular plate 18 to deflect on the surface of the limit claw 23. The deflection of the triangular plate 18 then causes the second rotating block 19 to deflect. The deflection of the second rotating block 19 then drives the pressure claw 20 to deflect on the surface of the fixed claw 22, so that the artificial The leather is clamped and fixed without the need to adjust the four pressure claws 20 in steps, which is convenient to use. Then the first electric push rod 4 is started. The operation of the first electric push rod 4 can drive the resistance rod 8 to move downward. The resistance rod 8 moves downward and then drives the pressure sensor 9 to move downward until the pressure sensor 9 contacts the artificial leather. At this time, the display screen 7 observes the pressure value of the pressure sensor 9. When the pressure applied by the resistance rod 8 is in place, the operation of the first electric push rod 4 can be stopped, and then the deformation degree of the artificial leather can be observed to detect the softness and hardness of the artificial leather.

[0037] Example 2:

[0038] See also Figure 1-9In this embodiment, four pressing claws 20 are provided and are located on the surface of the supporting base frame 1 near its four corners. The bottom surface of each pressing claw 20 is fixedly connected to a pressing plate 21. The bottom surface of the pressing plate 21 is fixedly connected to upper serrations 28 distributed at equal intervals. The surface of the placement block 26 is fixedly connected to lower serrations 27 distributed at equal intervals. The upper serrations 28 and the lower serrations 27 are arranged crosswise with each other. When clamping, the artificial leather can be placed between the upper serrations 28 and the lower serrations 27, thereby increasing the friction between the pressing plate 21 and the placement block 26 on the artificial leather, thereby ensuring that the artificial leather will not slip due to pressure during the test, thereby improving the accuracy of the test results.

[0039] When this testing device is used for testing, the artificial leather is pressed by the pressing plate 21, and the upper serrations 28 and the lower serrations 27 cooperate to increase the friction between the pressing plate 21 and the placement block 26 on the artificial leather, ensuring that the artificial leather will not loosen due to pressure during the test.

[0040] After use, the first electric push rod 4 is controlled to retract, and then the resistance rod 8 is restored to its initial state, and then the second electric push rod 11 is controlled to operate, so that the pressure claw 20 moves in the direction away from the artificial leather, so that the tested artificial leather can be taken out for the next round of testing.
