In order to ensure production quality, corresponding exhaust and dust collection pipes will be installed at the corresponding positions to suck away the above foil dust, foil scraps, paper scraps and other debris. Since foil dust, foil scraps, paper scraps and other debris will occasionally adhere to and accumulate in the pipes, volatile substances such as anhydrous ethanol and additives will also adhere to and accumulate in the pipes after cooling. After adhesion and accumulation, the exhaust suction will weaken or fail, resulting in quality risks in the products produced.
