Step 9：The surface labelled using flame pretreatment device to plastic hollow vessel carries out flame pretreatment, can
The firmness of label is improved, is not easy bulge or disengaging；
Step 10：Online labeling, is labelled using dual-purpose labelling machine, and different can produce needs, Online Video inspection
Label is to mistake, position, aberration problem；
Step 11：Plastic hollow vessel is leaked hunting using secondary leak-checking apparatus, plastics when preventing flame pretreatment
There is side leakage in hollow container, improves plastic hollow vessel quality；
Step 12：Detect qualified product and carry out stacking packaging into pile packing machine, into automatic stacking packing machine
Packing, adjust automatically transports, speed of packing；
Step 13：Perfect predictive maintenance demand.By the human-computer interaction interface (HMI) of bottle blowing machine, can check with figure
The process data for each bottle blowing process that mode records.So, operator's can fully understands the general status of processing performance,
Machine can also remind operator to pay attention to potential inconsistence problems, it is indicated that the product of which process exceeds acceptable tolerance model
Enclose, operator can easily identify the abnormal process of operation, formulate necessary maintenance plan, farthest reduce to production
Influence；Totally reduce maintenance workload and required manually operated, significantly save labour and control cost.
The step 4 is specific as follows：Heated using electromagnetic induction heating device, set blow molding process parameter, pass through
Above-mentioned parameter is adjusted to set pre- blowing reference curve, feedback control extrusion melt amount, melt is entered machine by predetermined flow rate
Head, when storing amount reaches predetermined value, machine head port mould is opened, and type embryo flexible neck is adjusted to axial wall thickness, real-time monitor-type
Germ wall is thick and feeds back, and automatic adjustment germ wall is thick, makes product Thickness Distribution evenly；
The step 5 comprises the following steps：
Step A：Pre- blowing aeration phase, the blowing curve in each blowing station of auto-real-time monitoring, if blow molding process
Parameter curve deviates reference curve, then correction can be performed automatically, when making the pre- blowing of each actual blow mold stage in all blowing station
Between start blowing and duration and blowing pressure, it is completely the same with setting value, ensure that the accurate with one of material distribution
Cause property；
Step B：Stage pressure period, mould carry out matched moulds according to the speed of setting, require stable movement, left and right during matched moulds
Balance, blown after matched moulds, parison is close to mould inner wall in the presence of gas pressure, is opened after keeping pressure cooling and shaping
Mould, each blow molded product is persistently adjusted, it is ensured that each blow molded product meets standard.
Maintenance alarm when the mould clip that the step 6 also includes removal rim charge structure breaks down.
Present invention has the advantages that：Operation is based on continuing, automatic process adjustments, without any manual intervention, exactly
Container stock in distribution, monitors online wall thickness measuring feedback in real time and automatic adjustment germ wall is thick, makes product Thickness Distribution more equal
It is even, solve the problems, such as that wall thickness differs, improve hollow container quality, solve that percent defective is higher, the recovery of waste material, utilize difference, system
The problems such as thickness control of product, the dispersiveness of raw material are restricted, energy consumption is big, speed-raising is difficult, can effectively ensure that production quality, produce
