1. Upgrade to Servo Motor Drive:
a. Preform Feeding System: Servo Motor controls, high speed and precisely positioning.
Preform Feeding Chain adopts composite Nylon polymer, light, wear resistant, no deformation. Dimension on Nylon chain is made according to Preform Neck size. Perfect matching to avoid preform stuck and reduce friction between preforms.
b. Preform Transfer System: preforms horizontal movements are driven by Servo Motor. Make preforms 4pcs/6pcs as one unit, overall simplified stepping motion, achieve high-speed positioning and smooth motion. To complete one step cycle, the Servo Motor drive gear rotate only one-third of a turn. Speed of preform moving is 2 times of Cylinder Driven way.
2. Mold fixing by Drawer Design.
Push the mold, fix the positioning screws. Mold changeover work can be easily done in half hour.
3. Efficiency Constant Temperature Oven:
a. The most advanced high frequency Infrared Lamp, increase heating efficiency 30%－50%.
b. Each layer of lamp are separately controlled, with assistant ruler on machine.
c. Intelligent temperature control system.
Temperature detector feedback to PLC automatically, PLC makes accurate judgment and then control circulation air in oven. It leads to constant temperature in Oven, free from voltage fluctuations and ambient temperature. It works when large ambient temperature difference (-28~45 ℃).
d. Preform self-rotation System, ensure every side of every preforms are heated evenly, which ensure quality of blown bottle.
e. Neck Cooling in Oven.Preform Necks are cooled by recycling water, which avoid neck deformation.
