7. control system as claimed in claim 6, it is characterized in that, the described first additive control module (041) receives inventory n1 data from total control module (00), and the feed amount of the conveying pipeline (411) of corresponding adjustment first spray equipment (41), thereby adjust from the inventory n1 of spray material port (412) ejection;
The described second additive control module (042) receives inventory n2 data from total control module (00), and the feed amount of the conveying pipeline (421) of corresponding adjustment second spray equipment (42), thereby adjusts from the inventory n2 of spray material port (422) ejection.
8. control system as claimed in claim 7, it is characterized in that, described total control module (00) reads the transfer rate V2 of prefabricated data and the mass flow n that locates according to discharging opening (12), post processing conveyer (32), the inventory n1 of first spray equipment (41) spraying, determine the hot air flowrate m1 that described first drying unit (51) is discharged, and transmit it to the first oven dry control module (051);
Described total control module (00) reads the transfer rate V2 of prefabricated data and the mass flow n that locates according to discharging opening (12), post processing conveyer (32), the inventory n2 of second spray equipment (42) spraying, determine the hot air flowrate m2 that described second drying unit (52) is discharged, and transmit it to the second oven dry control module (052);
The hot air flowrate m1 that described first drying unit (51) is discharged is 1～2.5 times of the hot air flowrate m2 that discharges of second drying unit (52).
9. control system as claimed in claim 8, it is characterized in that, the described first oven dry control module (051) receives hot air flowrate m1 data from total control module (00), and the air demand of the breather pipe (511) of corresponding adjustment first drying unit (51), thereby adjust the hot air flowrate m1 that discharges from exhaust outlet (512);
The described second oven dry control module (052) receives hot air flowrate m2 data from total control module (00), and the air demand of the breather pipe (521) of corresponding adjustment second drying unit (52), thereby adjusts the hot air flowrate m2 that discharges from exhaust outlet (522).
10. control system as claimed in claim 9 is characterized in that, described total control module (00) was an one-period with 10 minutes～1 hour, periodically read the extruded velocity V that prefabricated data are determined extruder
0, and carry out as the described control program of claim 2～9.
