The Yuda fully automatic bottle blowing machine adopts a touch sensitive color human-machine interface control system, which is easy to operate. The maximum capacity for blowing is 20L, and the output can reach 1300 bottles per hour. A bottle outlet connection mechanism can be installed at the bottle outlet, which can be connected to the filling machine through the conveyor to reduce secondary bottle contamination and save labor. The machine adopts a tight high-pressure combination gas valve and is equipped with a high-pressure gas recovery device, with a gas recovery efficiency of up to 40%, reducing equipment investment and power consumption of low-pressure gas by 15%. The main components of the machine consist of variable pitch transmission design, uninterrupted rotating heating system, and high-speed mold closing. The optimized machine layout and energy-saving preform heating system save more than 40% energy compared to traditional methods。
