Discharge mechanism for coating adhesive tape after cooling

The invention discloses a discharge mechanism for coating adhesive tape after cooling. The discharge mechanism comprises a machine frame, a cooling mechanism, a cleaning device, checking light sourceand a rolling-up device. The cooling mechanism, the cleaning device, the checking light source and the rolling-up device are arranged on the machine frame from left to right. The cooling device comprises a cooling cylinder, a roll shaft below the cooling cylinder and a liquid supply assembly. The cooling cylinder and the roll shaft below the cooling cylinder are arranged on the machine frame, theliquid supply assembly is arranged on one side of the machine frame, the liquid supply assembly is connected to the cooling cylinder, and the roll shaft below the cooling cylinder is arranged below the cooling cylinder. The checking light source is arranged below the middle between the cleaning device and the rolling-up device, and used for irradiating strong light on thin film. The thin film canobtain irradiation from the
