The closing of obstruction free turning arm 45.
One working cycles of cake discharge preformer 4 and constant feeder 5（Cake is unsnatched, material is filled）About 20min, oil press 2
One working cycles about 600min, so 30 oil presses 2 are just right with 1 cake discharge preformer 4 and 1 constant feeder 5, and
The speed of travel of AGV dollies 7 is 30~50m/min, most long haul distance 60m, and the average once transport material time is no more than 5min, pressed
This is calculated（Plus the charging interval）, totally 90 oil presses 2 are equipped with 3 AGV dollies just properly to 3 production lines.
The oil expression step of the vegetable oil cold press system is：Start calling AGV dollies 7 after oil press 2 is ready to, AGV is small
The mobile squeezing cylinder 3 for filling oil plant is just transplanted on the lower section of platen 213 of the oil press 2 by car 7, and after having good positioning, AGV dollies 7 are withdrawn from,
The automatic of oil press 2 squeezing program carries out squeezing work, and super-pressure duplex pump driving high-low pressure hydraulic oil enters squeezing hydraulic pressure
The epicoele of cylinder 212, the expansion link of squeezing hydraulic cylinder 212 starts quickly to move down, and precompressed is carried out, when pressure rises to set pressure（Such as
8MPa）When, precompressed terminates, pumping plant low pressure relief valve（Pressure setting 8MPa）Off-load, by the high-pressure plunger in super-pressure duplex pump
Oil pump feed is squeezed, according to different oil plants, is worked out corresponding program, is realized pressurization-shutdown-pressurization-shutdown, so repeatedly,
Until completing, it is ensured that high oil recovery.Extract oil after end-of-job, PLC control reversal valve commutations, super-pressure duplex pump output hydraulic pressure is oily
Into squeezing hydraulic cylinder cavity of resorption and opening hydraulic control one-way valve, squeezing hydraulic cylinder piston rod starts to retract.Hydraulic cylinder piston rod is retracted
