Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coiled material stress, and in particular to a waterproof coiled material stress relief device. Background Art

[0002] The internal stress of waterproof membrane is the internal residual stress generated by deformation constraint during its production, construction or use, which directly affects the durability and failure risk of the waterproof layer. The performance of waterproof membrane under stress is a key indicator for evaluating its durability and waterproof effect. Moderate internal stress can improve the initial bonding strength between the membrane and the base layer. When the internal stress of the waterproof membrane exceeds the tensile strength of the material, it will cause cracking. Insufficient stress relaxation will lead to long-term creep, accelerating the peeling and failure of the lap joints.

[0003] In the existing waterproof membrane production technology, when producing waterproof membranes, most waterproof membranes are composite multi-layer structures. Therefore, during the membrane lamination or compounding process, the difference in shrinkage rates of different material layers leads to uncoordinated deformation, which causes interface residual stress in the waterproof membrane during the production process. The existing waterproof membrane production line usually adopts natural cooling when cooling the waterproof membrane after high-temperature molding. The difference in cooling rate between the surface and the core causes asynchronous shrinkage, triggering self-balancing thermal stress, making it impossible to release internal stress, causing the structure of the waterproof membrane to be destroyed, the waterproof performance to decay, and the crack propagation rate of the waterproof membrane to be accelerated, seriously affecting the quality of the waterproof membrane.

[0007] By adopting the above technical solution, through the provided waterproof membrane body, when it is necessary to reduce the stress generated inside the waterproof membrane body during production, the waterproof membrane is first wound around the outer circular wall surface of the transmission rod, and then the stepper motor is started.

Through the temperatures set in each tank, the waterproof membrane body 2 undergoes three heating and cooling cycles. The first cycle can eliminate the forming stress generated in the production process, the second cycle can release the molecular chain orientation stress, and the third cycle can balance the shrinkage difference between the crystalline area and the amorphous area. The temperature gradient decreasing design effectively avoids thermal shock of the material.

[0055] Working principle: Please refer to Figures 1-12As shown, by adopting the above technical solution, by setting the waterproof roll body 2, when it is necessary to reduce the stress generated inside the waterproof roll body 2 during production, first the waterproof roll body 2 is wound around the outer wall of the transmission rod 10, and then the stepper motor 9 is started. The stepper motor 9 drives the drive shaft to rotate clockwise to drive the transmission rod 10 to rotate clockwise, and then the transmission wheel 11 starts to rotate clockwise, and then the synchronous belt 12 starts to rotate clockwise, and the synchronous belt 12 drives the driven wheel 13 to start rotating clockwise, and then the driven rod 14 starts to rotate clockwise, and then the waterproof roll body 2 is driven by the transmission rod 10, in sequence When passing through the first heating tank 3, the first cooling tank 4, the second heating tank 5, the second cooling tank 6, the third heating tank 7 and the third cooling tank 8 at a certain rate, the waterproof membrane body 2 is heated to different temperatures. The internal stress of the waterproof membrane body 2 is released after continuous heating and cooling due to the principle of thermal expansion and contraction, thereby improving the waterproof performance of the waterproof membrane body 2 and reducing the risk of warping and cracking of the waterproof membrane body 2 caused by the internal stress inside the waterproof membrane body 2.

[0056] Through the set temperature sensor 45, when it is necessary to control the temperature of the heating tank and the cooling tank, the temperature sensor 45 is turned on. The temperature sensor 45 can sense the temperature in each tank in real time. When the temperature in a tank exceeds the set temperature for heating the waterproof membrane body 2, the temperature sensor 45 transmits a signal to the PLC controller 39, and then the PLC controller 39 controls the start of the electric push rod 26 and the exhaust fan 40, stops the heating supply and discharges the hot air in the heating tank or the cooling tank through the exhaust fan 40, so that the temperature in the heating tank or the cooling tank is reduced, avoiding the temperature in the tank being too high, so that the stress in the waterproof membrane body 2 cannot be reduced in time, and the quality of the waterproof membrane body 2 is reduced.

[0057] Through the set resistance wire 19, when it is necessary to heat the first heating tank 3, the first cooling tank 4, the second heating tank 5, the second cooling tank 6, the third heating tank 7 and the third cooling tank 8, the resistance wire 19 is first energized and then heated, and then the blower body 17 is started, and the air outlet of the blower body 17 transports the heated air to the first heating tank 3, the first cooling tank 4, the second heating tank 5, the second cooling tank 6, the third heating tank 7 and the third cooling tank 8 through the heating pipe 18 for heating, thereby facilitating the heating of the first heating tank 3, the first cooling tank 4, the second heating tank 5, the second cooling tank 6, the third heating tank 7 and the third cooling tank 8 to the required temperature, and facilitating the heating of the waterproof membrane body 2 to a suitable temperature.

[0058] Through the one-way door 35, when it is necessary to perform regular inspection on the inside of each groove, the one-way door 35 is pulled to rotate clockwise around the fixing rod 47, and then the U-shaped block 38 moves toward the one-way door 35, and the return spring 37 is compressed. At this time, the one-way door 35 is opened. When it is necessary to heat the waterproof membrane body 2, the one-way door 35 is turned to rotate counterclockwise around the fixing rod 47, and then the U-shaped block 38 moves toward the one-way door 35, and the return spring 37 is compressed. When the U-shaped block 38 passes through the locking groove 34, the force generated by the deformation of the return spring 37 causes the U-shaped block 38 to move away from the one-way door 35. At this time, the one-way door 35 is closed, so that subsequent staff can heat the waterproof membrane body 2.

[0059] By setting the heating and cooling of the first heating tank 3, the first cooling tank 4, the second heating tank 5, the second cooling tank 6, the third heating tank 7 and the third cooling tank 8 to a constant temperature, the waterproof membrane body 2 is passed through the first heating tank 3, the first cooling tank 4, the second heating tank 5, the second cooling tank 6, the third heating tank 7 and the third cooling tank 8 for the first time through the transmission rod 10. Through the temperatures set in each tank, the waterproof membrane body 2 undergoes three heating and cooling cycles. The first cycle can eliminate the forming stress generated in the production process, the second cycle can release the molecular chain orientation stress, and the third cycle can balance the shrinkage difference between the crystalline area and the amorphous area. The temperature gradient decreasing design effectively avoids thermal shock of the material.
