The four and a half automatic bottle blowing machine adopts an advanced microcomputer control system, with manual and fully automatic modes, stable performance, simple and convenient operation. The feeding machine adopts a stainless steel oil-free conveyor belt, automatic control of the billet feeding device, low noise, long service life, and other advantages. It uses infrared light tube heating, strong penetration power, and the preform rotates and heats evenly, fast and reliable. The width and height of the light tube and reflection plate in the heating zone can be adjusted, suitable for heating different structures of preforms, and there is an automatic temperature control device, ideal cooling effect, to ensure the constant temperature of the drying channel, greatly reduce the scrap rate of finished products. The mold clamping system adopts a double curved arm connecting rod mold locking, with large locking force and no expansion, and each mechanical action has a safety self-locking device. When a process malfunctions, the program will automatically sound an alarm and switch to a safe state, The air circuit design divides the action and blowing into two parts to meet the different requirements of blowing pressure and action pressure, so as to prevent contamination of the bottle body. The unique valve position design also makes the air circuit clear at a glance. Each action is driven by the air source, with the advantages of no pollution and low noise. The production process is fully automated, with the advantages of low investment, high efficiency, easy operation, simple maintenance, safety, etc. The machine installation is simple and convenient, and the fully automatic bottle blowing machine can completely replace similar imported equipment at a very reasonable price
