A laminating machine for use in a metal film switch manufacturing process. The laminating machine comprises a frame and a driving device, a control device and a film material support arranged on the frame, the frame comprises a frame body and a horizontal operation plate disposed on the top of the frame body, wherein the operation plate is provided at the center a through hole; the material support includes two pillars disposed on opposite sides of the through hole and a cross bar disposed on the two pillars; the driving device includes an upper roller disposed above the operation panel, and is disposed a lower roller on the three or three lower sides of the operation panel, a conveyor belt that is sleeved on the lower drum, and a motor that drives the lower drum, the upper roller and the lower roller are disposed across the through hole, directly below the upper roller A lower drum is provided; the control device is a control box that controls the motor. The invention provides a production equipment with simple operation, improves the production efficiency of the membrane switch coating process, and greatly reduces the incidence of defective products in the film coating process.

              In order to overcome the lack of rapid change mechanism of the laminating machine in the original color coating production line, the laminating machine has the advantages of poor working efficiency, poor precision, slow response, and large labor intensity of manual alignment. The technical solution adopted by the present invention is one. The laminating machine is composed of an uncoiler, a looper and a press machine, and the uncoiler is fixed on the base of the looper, and the press machine is installed on the production line, and the laminating machine of this structure can be quickly changed, Continuous production, automatic centering, automatic flattening, and temperature adjustment function, greatly improve work efficiency and save production costs.
