The signal, when the numerical value that the performance indications parameter drift-out of target product sets, is fed back to control unit, control unit weight by number
It is new to calculate the plastic raw materialss required ratio obtained in each area spice storage tank, and output control signal controls area's automatic gauge
Device weighs corresponding plastic raw materialss in the ratio.
9. recycled plastic regenerating and modifying production method according to claim 8, it is characterised in that the production line unit
Quantity is two or more, and these production line units are set up in parallel, and the plastic grain obtained in each production line unit is by certain
Ratio mixes, and obtains mixed plastic particles, specifically, in step (4)：
Sampling detecting device on three area's spice storage tanks is to the plastics in tri- area's spice storage tanks of corresponding production line unit Zhong
Performance indications parameter in grain is detected, and the testing result is fed back to control unit；Control unit is according to final needs
Mixed plastic particles in performance index parameter require, calculate obtain each production line unit in plastic grain required ratio,
And output control signal controls two area's self-measuring devices and corresponding plastic raw materialss weighed in the ratio, and be transported to four area's spices
Homogenizing is stirred in storage tank, mixed plastic particles finished product is obtained；
Additionally, further comprising the steps of：
The property of mixed plastic particles finished product in four area's spice storage tank of sampling detecting device real-time detection on (5) four area's spice storage tanks
The signal, when mixed plastic particles end properties index parameter deviates the numerical value of setting, is fed back to control by energy index parameter
Unit processed, control unit recalculate the target product required ratio obtained in each 3rd areas spice storage tank, and output control letter
Number control two area's self-measuring devices weigh corresponding plastic raw materialss in the ratio.
