At this time, the first fixed roller 42 and the second fixed roller 43 are both in contact with the architectural glass. The EVA intermediate film is in contact with each other, so as to fix the architectural glass EVA intermediate film on the top of the vibration table 6. The motor 52 is started, and the rotation of the motor 52 drives the turntable 53 to rotate. The rotation of the turntable 53 drives the first rotating block 54 to rotate. The rotation of the first rotating block 54 drives the connecting rod 55 to move. The movement of the connecting rod 55 drives the second rotating block 56 to move horizontally.

When one side of the support platform 51 moves, the two groups of springs 41 on the side away from the support platform 51 are in a compressed state, and the two groups of springs 41 on the side close to the support platform 51 are in a stretched state. The changes in the expansion and contraction states of the four groups of springs 41 ensure the horizontal reciprocating motion of the vibration table 6, while preventing the vibration table 6 from colliding with the fixed frame 4 and causing damage, thereby producing a vibration effect on the EVA intermediate film on the vibration table 6, causing the bubbles to float up and detach from the film surface, helping the bubbles to escape, and at the same time starting the water pump 612 to accelerate the flow rate of water inside the refrigeration pipe 61. The water flows through the refrigeration pipe 61 to produce a refrigeration effect, cool the architectural glass EVA intermediate film on the vibration table 6, accelerate the curing process of the architectural glass EVA intermediate film, and reduce the cooling time.
