Automatic PET Bottle Blowing Machine

Key Features:

1. 1. All-electric servo control for stable, precise operation.
   2. Reduced high-pressure air and energy consumption.
   3. Oil-free, self-lubricating bushing technology.
   4. Mold change completed within approximately 20 minutes.
   5. Mitsubishi PLC and HMI with storage for over 100 recipes.
   6. Automatic bottle ejection and preform temperature monitoring.

Working principle:

1. Firstly, the quality preforms are elevated and unscrambled by the auxiliary equipment, after unscrambling, the preforms are send the railway orderly. This railway allows the preforms are sendtto host blowing machines by self-gravity.
2. The preforms are caught and uploaded by rotary clamping hands to each heater heads, this movement is driven by mechanical cam in a soft and continuous way to make sure the high efficiency and the high stability.
3. The robot hand then send preforms to blowing section. In this section we combine movements of bottom mold elevate, side mold camping, mold locking and up mold falling in one mechanical cam, this is the key. This design much simplifies the machine structure, all the movements are now controlled by mechanical cam instead of equipping many sensors, each mechanical movement has more logistical rules interlinked.
4. This cam is controlled by servo motor only. In this section, one water chilled will supply chilled  water to give quick cooling for the mold.
5. After bottle blown up, they are caught by another robot hand to the conveyor which can be linked to the filling machine, this robot hand is driven by the same servo motor of the one who send preforms to the blowing station.
