The workpiece is covered with a layer of film by the film covering roller 11 as the conveying belt moves. If bubbles or wrinkles appear due to insufficient tension of the film at this time, the electric slide rail 143 of the film guide device 14 can be started to drive the electric slide block 142 to move forward, so that the film guide roller 144 moves forward to provide tension. After the film is attached, the workpiece is moved to the collection frame on the rear side with the conveying member 3.
