When the product completely passes between the second pressure roller unit 42 and the third pressure roller unit 62, the product is rolled between the third pressure roller unit 62 and the transmission belt 200 of the third conveying unit 61. At the same time, the sensor 56 sends a signal to the controller 70, and the controller 70 controls the first conveying unit 31, the second conveying unit 41, and the third conveying unit 61 to stop working, and controls the rodless cylinder 52 to drive the cutting knife 51 to cut the protective film. After the cutting is completed, the controller 70 controls the first conveying unit 31, the second conveying unit 41, and the third conveying unit 61 to resume working, and the cutting mechanism 50 stops working.

[0055] Step 4: Discharging process: the third conveying unit 61 conveys the coated product to the discharging end. Thus, a complete feeding, coating, cutting and discharging process is completed.
