A feeding mechanism 15 is installed inside the box body 10, which provides power to the foil 120. The coating mechanism 13 is installed on the surface of the housing 1 and located on the conveying path between the box body 10 and the oven 12, and is used to coat the surface of the foil 120 with coating. The conveying path of the foil 120 is as follows: after being released from the feeding mechanism 15, it passes sequentially through the interior of the box body 10, the coating mechanism 13, and the oven 12, and is finally wound up by the winding mechanism 14, forming a continuous coating-drying-winding operation process.

The air intake unit 115 is started, and fresh air or circulating air enters the air intake hood 114 through the air intake pipe 113 and passes through the through hole 32. After entering the filter box 31 and being filtered by the large-hole filter plate 35 and the small-hole filter plate 34, the air is distributed by the air inlet box 112 to each air nozzle 111 and blown evenly onto the surface of the foil 120. The temperature sensor 106 and the humidity sensor 1061 detect the environmental parameters of each temperature zone in real time. The controller 11 adjusts the power of the heating rod 43 and the speed of the air inlet unit 115 and the exhaust unit 117 according to the detection data to accurately control the parameters of each temperature zone. When the exhaust unit 117 is started, the solvent-containing gas inside the oven 12 enters the exhaust box 116 through the exhaust pipe 118, is sent to the heat exchanger 119 for treatment, and is then discharged. After drying, the foil 120 is corrected by the deviation correction component 122 and then wound up by the winding roller of the winding mechanism 14. If the first tension sensor 101 or the second tension sensor 104 detects an abnormal tension, the controller 11 immediately activates the audible and visual alarm 105 and adjusts the speed of the feeding motor and the winding motor to ensure stable operation.
