[0002] Self-adhesion is the phenomenon that the same unvulcanized rubber is bonded and left for a certain period of time to fuse together. It is the result of the mutual diffusion and penetration of the rubber macromolecules on the two sides through molecular thermal motion. Self-adhesion is very important in the molding process, so it is also called molding viscosity. The self-adhesion tester is suitable for testing the viscosity properties of various types of rubber, and can analyze and characterize the viscosity properties of unvulcanized rubber.

[0003] At present, the method of applying pressure with a single weight is usually adopted. By replacing weights of different weights, different loads are applied to the rubber to detect the self-adhesion of the rubber.

[0004] However, when the above device is used to test the self-adhesiveness of rubber, the weights need to be replaced repeatedly to improve the accuracy of the test, which results in more operating steps for testing the self-adhesiveness of rubber and is inconvenient to use. Therefore, improvements are needed by the staff. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figures 1 to 5A variable load pressurizing device for a rubber self-adhesive testing machine comprises an operating box 1, the inner wall of the operating box 1 is rotatably connected to a rotating rod 2, the front end of the rotating rod 2 is fixedly connected to a knob 3, the top of the knob 3 is fixedly connected to a compass 4, the surface of the rotating rod 2 is fixedly connected to a torsion spring 5, the surface of the torsion spring 5 is fixedly connected to a rotating cylinder 6, and the inner wall of the rotating cylinder 6 is sleeved on the surface of the rotating rod 2, the surface of the rotating cylinder 6 is wound with a connecting rope 7, the top of the connecting rope 7 is fixedly connected to a limiting block 8, the top of the limiting block 8 is fixedly connected to a hook 9, the top of the operating box 1 is fixedly connected to a lap block 10, and the surface of the limiting block 8 is lapped on the top of the lap block 10, the left and right sides of the top of the operating box 1 are fixedly connected to a connecting frame 11, the middle part of the connecting frame 11 is fixedly connected to a placing plate 12, and the tail end of the bottom of the connecting frame 11 is fixedly connected to a supporting rod 13.

[0026] When using this device to test the self-adhesiveness of rubber, the hook 9 is hooked on the tail of the rubber, and then the rubber is laid flat on the top of the placement plate 12. At this time, the self-adhesiveness of the rubber can be tested. The knob 3 is turned to make the knob 3 drive the rotating rod 2 at the tail to rotate, and the rotating rod 2 drives the torsion spring 5 on the surface to rotate. At this time, the protrusions at both ends of the torsion spring 5 are stuck in the inner wall of the rotating cylinder 6, so that the torsion spring 5 drives the rotating cylinder 6 to rotate, and the torsion spring 5 is squeezed by the weight of the rotating cylinder 6. The rotating cylinder 6 drives the surface connecting rope 7 to reel up, and the connecting rope 7 drives the limit block 8 at the top to move. The limit block 8 drives the top hook 9 to move, and the hook 9 pulls the rubber. The self-adhesiveness of the rubber drags the hook 9, so that the connecting rope 7 is restricted and difficult to rewind, so that the rotating cylinder 6 is difficult to rotate. At this time, the knob 3 drives the torsion spring 5 to rotate, so that the torsion spring 5 is squeezed, and then the pulling force pulling the rubber is increased, so that the self-adhesiveness of the rubber is detected according to the pulling force and the moving distance of the rubber.

[0027] See also Figures 1 to 5 , a variable load pressurizing device for a rubber self-adhesive testing machine: a sliding plate 14 is fixedly connected to the left side of the left connecting frame 11, a connecting rod 15 is slidably connected to the inner wall of the sliding plate 14, a push-pull ring 16 is fixedly connected to the tail end of the connecting rod 15, a plug-in block 17 is fixedly connected to the front end of the connecting rod 15, buttons 18 are slidably connected to the left and right sides of the inner wall of the connecting rod 15, a connecting plate 19 is fixedly connected to the tail end of the button 18, a fixed block 20 is slidably connected to the left and right sides of the inner wall of the plug-in block 17, and the tail end of the fixed block 20 is fixedly connected to the front of the connecting plate 19, connecting springs 21 are connected to both sides of the inner wall of the plug-in block 17, and the front end of the connecting spring 21 is connected to the back of the connecting plate 19, a cleaning wipe 22 is slidably connected to the surface of the plug-in block 17, and the front end of the fixed block 20 is plugged into the inner wall of the cleaning wipe 22.

[0028] When cleaning the placement plate 12 with the cleaning wipe 22, hold the push-pull ring 16, and then push the push-pull ring 16, so that the push-pull ring 16 drives the connecting rod 15 to slide telescopically on the inner wall of the sliding plate 14, and the connecting rod 15 drives the front end plug-in block 17 to move back and forth, and the plug-in block 17 drives the cleaning wipe 22 to move back and forth, and makes the cleaning wipe 22 rub on the surface of the placement plate 12. When the rubber residue cannot be wiped off, alcohol or water can be poured into the cleaning wipe 22, so that the rubber residue on the surface of the placement plate 12 can be wiped off with the cleaning wipe 22. When the cleaning wipe 22 needs to be replaced, press the button 18 so that the button 18 drives the connecting plate 19 at the tail end to retract into the inner wall of the connecting rod 15 and the plug-in block 17, and the connecting plate 19 drives the fixed block 20 to retract into the inner wall of the plug-in block 17. At this time, the cleaning wipe 22 is disengaged, so that the cleaning wipe 22 can be removed and replaced with a new cleaning wipe 22.

[0029] Working principle: press the button 18 to drive the fixed block 20 to retract into the plug-in block 17, then insert the plug-in block 17 into the new square groove of the cleaning wipe 22, and then release the button 18, so that the connecting spring 21 rebounds and pushes the fixed block 20, so that the fixed block 20 is inserted into the groove of the square groove of the cleaning wipe 22, thereby connecting and fixing the plug-in block 17 and the cleaning wipe 22, and then push and pull back the push-pull ring 16, so that the cleaning wipe 22 rubs back and forth on the surface of the placement plate 12, thereby removing the rubber residue on the surface of the placement plate 12, and then hang the hook 9 on the tail of the rubber and spread it flat on the surface of the placement plate 12, and then turn the knob 3 to make the torsion spring 5 rotate and be squeezed by the rotating cylinder 6, so that the hook 9 is subjected to the tension of the torsion spring 5, so that the tension pulls the rubber, and the knob 3 is continuously turned to adjust the tension of the hook 9 on the rubber, and then the self-adhesiveness of the rubber can be tested.
