PET Empty Bottle (Hygienic Type) Air Duct Conveyor Line The PET Empty Bottle (Hygienic Type) Air Duct Conveyor Line uses the wind energy of the fan as the transportation power, and is equipped with an air storage bottle conveying duct to realize the production of PET empty bottles (hygienic type) from the bottle blowing machine. Empty bottles are directly transported to the filling machine or labeling machine for filling or labeling. The main structural parts of the air duct are made of 304 stainless steel, which can resist corrosion by various weak acids and weak alkali. The air duct bottle clamping strip is made of ultra-high molecular polyethylene material, which has low friction resistance and high wear resistance, ensuring long-term use. life. The entire electrical system is controlled by PLC, human-machine interface, frequency converter and photoelectric sensor. It can reduce secondary pollution of empty bottles, save packaging costs and save labor costs. The system has the characteristics of energy saving, compact structure, beautiful appearance, simple control, easy adjustment, and easy cleaning. It meets the hygienic requirements of the food and packaging industries and is an ideal bottle conveying mechanical equipment. The PET empty bottle air duct conveyor line is composed of a fan power device, a straight air duct, a turning air duct, an uphill and downhill air duct, a dividing and merging device, a bottle dropping device and a bottle clamping device.
