1.1、Closing part

By the positioning rack balance positioning, front, middle and back three pieces of template, double curved arm linkage mechanism,closing cylinder, through the electromagnetic direction control valve to drive the cylinder linkage curved arm to achieve open and close the mold. The structure is reasonably designed, with smooth operation and large clamping force.

1.2、Stretching and blowing part

It is composed of stretch solenoid valve, high pressure blowing valve, pulling body sealing cylinder, movable sealing seat and blowing storage cylinder. When working, the directional control valve pushes the piston of the stretching cylinder, which drives the stretching rod and sealing cylinder upward on the molded billet, the sealing cylinder seals the mouth of the billet, the stretching rod makes longitudinal stretching to the billet which has been heated to be elastic, and the gas stored in the storage cylinder is blown through the sealing cylinder by the high-pressure blowing valve to the billet after bottom blowing and high-pressure blowing and forming.

1.3、Heating chain plate is detected and positioned by photoelectric switch through one station of stepping cylinder, and then blown into products by forming mechanism, and the stepping cylinder is pushed to detect and position at one station, and the production is continuous from week to week.

1.4、The self-rotating chain is driven by the electric motor to work continuously, so that the bottle blanks in the baking tunnel are heated quickly and evenly.

1.5、Bottle blanks are conveyed and sorted by the feeding system, and then the blanks are installed on the blowing machine base by the feeding robot and enter the drying tunnel.
