A second power mechanism is fixedly installed on the outer surface of the bracket 5. Pressure rollers 11 are rotatably installed on the inner sides of the two moving blocks 8.
[0022] When the staff drives the positive and negative screw rod 4 on both sides through the first power mechanism to start rotating, and the both ends of the positive and negative screw rod 4 are penetrated into the inside of the two groups of support one 5, when the positive and negative screw rod 4 starts to rotate, it will drive the support one 5 on both sides to shrink inside, at this time, the second power mechanism is started to drive the gear mechanism to rotate through the controller, and the screw rod 9 extends out of the top of the support one 5, then the gear mechanism will drive the screw rod 9 to start rotating, when the screw rod 9 rotates, it will drive the moving block one 8 to start up and down displacement, when the moving block one 8 starts to move up and down, it will drive the moving block one 8 on both sides to move up and down synchronously through the compression wheel 11, then adjust the compression wheel 11 to the appropriate position, drive the compression wheel 11 to flatten the adhesive film through the transmission device, compared with the traditional device, the device can ensure that the adhesive film is subjected to uniform flattening force everywhere, avoid the deformation difference of local microstructure, finally improve the micro flatness of the adhesive film, different batches of pressure sensitive adhesive film keep high consistency in performance and size specifications, improve the reliability and interchangeability of the product.
