System, the quality controls of hollow container, frequently sampling and laboratory test are generally relied on, is adjusted manually further according to test result,
Not only time-consuming for this process, greatly reduces production line efficiency, and hollow container can not be completely secured and all meet rule
Case marker is accurate.The ultimate attainment lightweight of packaging modeling is constantly pursued in the industry, and blow molding process also becomes more crucial therewith.Given birth in hollow container
In production, product distribution is bad or unstable establish a capital may influence processing quality, even results in whole production line shut-down.
The content of the invention
For the above mentioned problem to be solved, the present invention provides a kind of extrusion glue embryo adjust automatically based on 3D scannings and control is squeezed
Go out the method for blowing.
Technical scheme：A kind of side of extrusion glue embryo adjust automatically and control extrusion-blown modling based on 3D scannings
Method, comprise the following steps：
Step 1：3D plastotypes or 3D drawing scannings are inputted using 3D scanners, collection technology parameter；
Step 2：According to collection technology parameter, automatically select appropriate flow rubber head and determine gummosis curve；
Step 3：Automatic batch mixing is according to gummosis head and gummosis curve, online aberration inspection feedback and adjust automatically color masterbatch ratio
Example；
Step 4：Heated using electromagnetic induction heating device, and blowout type embryo flexible neck is adjusted to axial wall thickness
Whole, real-time monitor-type germ wall is thick and feeds back, and automatic adjustment germ wall is thick, makes product Thickness Distribution evenly；
Step 5：Blow-molded process is entered according to predetermined process parameter, adjust automatically blowing pressure, tolerance, controls mould
Temperature, open mold speed and cycle, online outward appearance and kerf quality inspection feedback, to carrying out size, wall thickness etc. to blow moulding equipment
Automatic correction, final production goes out qualified product, the closed-loop automatic control of realization；
Preferably, the step 4 is specific as follows：Heated using electromagnetic induction heating device, setting blow molding process ginseng
Number, pre- blowing reference curve is set by adjusting above-mentioned parameter, feedback control extrusion melt amount, melt is passed through predetermined flow rate
Into head, when storing amount reaches predetermined value, machine head port mould is opened, and type embryo flexible neck is adjusted to axial wall thickness, in real time
Monitor-type germ wall is thick and feeds back, and automatic adjustment germ wall is thick, makes product Thickness Distribution evenly.
Preferably, 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：Pressure period, mould carry out matched moulds according to the speed of setting, require stable movement during matched moulds, left and right is put down
Weighing, blown after matched moulds, parison is close to mould inner wall in the presence of gas pressure, is molded after keeping pressure cooling and shaping,
Each blow molded product is persistently adjusted, it is ensured that each blow molded product meets standard.
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, it is higher to solve blowing production percent defective, the reclaiming of waste material, profit
With difference, the thickness control of product, the dispersiveness of raw material are restricted.
Embodiment
The embodiment of the present invention is explained below.
The present invention relates to a kind of extrusion glue embryo adjust automatically based on 3D scannings and the method for controlling extrusion-blown modling, including with
Lower step：
Step 1：3D plastotypes or 3D drawing scannings are inputted using 3D scanners, collection technology parameter；
Step 2：According to collection technology parameter, automatically select appropriate flow rubber head and determine gummosis curve；
Step 3：Automatic batch mixing is according to gummosis head and gummosis curve, online aberration inspection feedback and adjust automatically color masterbatch ratio
Example；
Step 4：Heated using electromagnetic induction heating device, and blowout type embryo flexible neck is adjusted to axial wall thickness
Whole, 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 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.
Step 5：Blow-molded process is entered according to predetermined process parameter, adjust automatically blowing pressure, tolerance, controls mould
Temperature, open mold speed and cycle, online outward appearance and kerf quality inspection feedback, to carrying out size, wall thickness etc. to blow moulding equipment
Automatic correction, final production goes out qualified product, the closed-loop automatic control of realization；
Step 5 includes following two step：
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：Pressure period, mould carry out matched moulds according to the speed of setting, require stable movement during matched moulds, left and right is put down
Weighing, blown after matched moulds, parison is close to mould inner wall in the presence of gas pressure, is molded after keeping pressure cooling and shaping,
