CPJ-PET-A4 is the fastest liner blow molding machine in mainland of China by now. CPJ-PET-A4 reaches around 4200BPH for 350ML bottle. Its baking tunnel is separated from the blow station so that time for mold opening is shortened with a result of speedy blowing and high output, damage to machine is lessened so as to keep reliable performance and prolong service life, as well as machine runs more smoothly and steadily.
CPJ-PET-A4 automatic stretch blow molding machine is equipped with patented preform loading system, which consists of two manipulators: rectilineal manipulator and overturning manipulator. The rectilineal manipulator moves preform with neck up to the preform holder, after heating, the overturning manipulator grips heated preform and overturn 180 put preform to blow station with neck down. After stretching and blowing, the bottle is taken off by overturning manipulator. The specially designed preform loading & bottle discharging system avoid possible damage to preform & bottle during transportation.
CPJ-PET-A4 is controlled by PLC. The whole process from preform feeding to bottle discharging is completed automatically with advantages of labor saving and no pollution. HY-A4consists of three main parts: preform loading system, Heater channel & blow station.
A. Stable performance with advanced PLC.
B. Conveying preforms automatically with conveyor.
C. Strong penetrability and good and swift distribution of the heat by letting the bottles rotate by itself and revolute in the rails simultaneously in the infrared preheater.
D. High adjustability to enable the preheater to preheat preforms in shapes by adjusting the light tube and the length of the reflecting board in the preheating area, and eternal temperature in the preheater with an automatic thermostatic apparatus.
E. High safeties with security automatic-locking apparatus in each mechanical action, which will make the procedures turn into a state of safety in case of a breakdown in certain procedure.
F. No contamination and low noise with the air cylinder to drive the action instead of the oil pump.
G. Satisfaction with different atmospheric pressure for blowing and mechanical action by dividing the blowing and action into three parts in the air pressure diagram of the machine.
H. Strong clamping force with high pressure and double crank links to lock the mold.
I. Two ways of operating: automatic and manual.
J. Safe, reliable, and unique design of the position of valve to make the air pressure diagram of the machine easier to understand.
K. Low cost, high efficiency, easy operation, easy maintenance, etc, with automatic technological process.
L. Contamination is avoided for the bottle body.
M. Ideal effect of the chilling with the chilling system.
N. Easy installation and starting
O. Low rejection rate: less than 0.3percent.
