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.
[0030] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a biomimetic adhesive material adhesion force testing mechanism, comprising a base plate 1, a measuring component fixedly connected to the upper right side of the base plate 1 for measuring the biomimetic adhesive material, a fixing frame 8 fixedly connected to both sides of the upper part of the base plate 1, a second motor 9 fixedly connected to the front side of the fixing frame 8, a rotating shaft 10 fixedly connected to the output end of the second motor 9, gears 11 fixedly connected to both sides of the outer side of the rotating shaft 10, a rack plate 12 meshing with the upper side of the gears 11, a fixing frame 14 fixedly connected to the upper side of the rack plate 12, and hydraulic rods 15 fixedly connected to both sides of the inner side of the fixing frame 14. A fixed plate 16 is fixedly connected to the output end of rod 15. A connecting plate 17 is fixedly connected to the side of fixed plate 16 that is close to it. Fixed boxes 18 are fixedly connected to both sides of connecting plate 17. The measuring component includes a support frame 2. The support frame 2 is fixedly connected to the upper right side of the base plate 1. A support plate 3 is fixedly connected to the front side of the support frame 2. A first motor 4 is fixedly connected to the upper side of the support plate 3. A connecting shaft 5 is fixedly connected to the output end of the first motor 4.

[0031] By starting the second motor 9, the rotating shaft 10 and gear 11 are driven to rotate. The rotation of gear 11 drives the rack plate 12 and the fixed frame 14 to move. At the same time, the movement of rack plate 12 causes the limiting block 13 to slide on the upper side of fixed frame 8. Then, the hydraulic rod 15 is started to drive the fixed plate 16, connecting plate 17, fixed box 18 and support base 25 to move. At the same time, the first motor 4 is started to drive the connecting shaft 5, winding roller 6 and coil 7 to rotate, which in turn drives the connecting frame 26 to slide on the upper side of fixed frame 14, which in turn drives the tension sensor 27 to move. This allows for repeated testing under different experimental conditions.
[0032] Reference Figure 1 , Figure 2 , Figure 4Ventilation ducts 19 are fixedly connected to both sides of the lower part of the fixed box 18. A temperature control component is fixedly connected to the upper side of the inside of the ventilation duct 19. The temperature control component is used to simulate different temperature detection conditions. A heat conduction plate 24 is fixedly connected to the upper side of the temperature control component. A support base 25 is fixedly connected to the upper side of the heat conduction plate 24. The temperature control component includes a fan 20, which is fixedly connected to the upper side of the inside of the ventilation duct 19. A filter screen 21 is fixedly connected to the lower side of the inside of the ventilation duct 19. A heating tube 22 is fixedly connected to the upper side of the inside of the fixed box 18.
[0033] By starting the fan 20, the gas is driven from the ventilation duct 19 into the fixed box 18. The filter 21 filters the gas, the heat-conducting plate 24 delivers the cold air, and then cools the biomimetic adhesive material. The heating tube 22 heats the biomimetic adhesive material, thus simulating and testing different temperature conditions.
[0034] Reference Figure 1 , Figure 2 , Figure 4 The rotating shaft 10 is rotatably connected inside the fixed frame 8, and the gear 11 is rotatably connected inside the fixed frame 8; the heating tube 22 is fixedly connected to the outside with a buckle 23, which is fixedly connected inside the fixed box 18; the upper sides of the fixed frame 14 are slidably connected with connecting frames 26, and the tension sensor 27 is slidably connected to the upper side of the support base 25; the rack plate 12 is fixedly connected to both sides with limit blocks 13, which are slidably connected to the upper side of the fixed frame 8.
[0035] The rotating shaft 10 is rotatably connected to the inside of the fixed frame 8, and the gear 11 is rotatably connected to the inside of the fixed frame 8, which serves to support and limit the rotating shaft 10 and the gear 11. The heating tube 22 is fixedly connected to the outside of the fixed box 18, and the fixed buckle 23 is fixedly connected to the inside of the fixed box 18, which serves to fix and support the heating tube 22. The connecting frame 26 is slidably connected to the upper two sides of the fixed frame 14, and the tension sensor 27 is slidably connected to the upper side of the support base 25, which facilitates the testing of biomimetic adhesive materials. Limiting blocks 13 are fixedly connected to both sides of the rack plate 12, and the limiting blocks 13 are slidably connected to the upper side of the fixed frame 8, which serves to support and limit the rack plate 12.
[0036] Working principle: When using this device, starting the second motor 9 drives the rotating shaft 10 to rotate, which in turn drives the gear 11 to rotate. The gear 11 then moves the rack plate 12, which in turn moves the fixed frame 14. Simultaneously, the rack plate 12 moves the limiting block 13 to slide on the upper side of the fixed frame 8. Then, starting the hydraulic rod 15 moves the fixed plate 16, which in turn moves the connecting plate 17, which in turn moves the fixed box 18, thereby moving the support base 25. At the same time, starting the first motor 4 drives the connecting shaft 5 to rotate, which in turn moves the winding roller 6. The rotating coil 7 causes the connecting frame 26 to move, allowing it to slide on the fixed frame 14, which in turn moves the tension sensor 27. This enables repeated testing under different experimental conditions, ensuring high repeatability and controllability of test data and reducing human error. By starting the fan 20, gas is drawn into the ventilation duct 19, where the filter 21 filters the gas. The gas then enters the fixed box 18 from the ventilation duct 19, where the heat-conducting plate 24 delivers cool air, thus cooling the biomimetic adhesive material. The heating tube 22 heats the biomimetic adhesive material, enabling the simulation of different temperature conditions to test the material's performance in practical applications.
