The specific embodiment
Below in conjunction with drawings and Examples a kind of aluminium oxide rolling of the utility model blanking control system technical scheme is further described.
As shown in Figure 1-Figure 3, a kind of aluminium oxide rolling blanking control system comprises startup/stop button 3, programmable controller 1, bucket type gauge 2, frequency converter 4, motor 5, high signal sensor 6, feed pipe 7, cylinder feeder 8, low level signal transducer 9, delivery duct 10, discharging opening 11, rotary encoder 12, described motor 5 passes through sprocket wheel, chain gear is connected with the axle of cylinder feeder 8, cylinder feeder 8 upper ends are connected with feed pipe 7 by discharging opening 11, feed pipe 7 one sides arrange high signal sensor 6, cylinder feeder 8 lower ends set out pipe material 10, and discharge pipe 10 1 sides arrange low level signal transducer 9; Described cylinder feeder 8 axle heads arrange rotary encoder 12.
Described upper computer 1 mouth that is arranged on control cabin is connected with bucket type gauge 2 by terminal 19,20, and bucket type gauge 2 mouths are connected with frequency converter 4 input ends by terminal 21,22, and frequency converter 4 mouths are connected with motor 5 input ends; Described high signal sensor 6 is connected with bucket type gauge 2 by terminal 11, and low level signal transducer 9 is connected with bucket type gauge 2 by terminal 10, and rotary encoder 12 mouths connect by terminal 15,16 bucket type gauge, 2 input ends; Described frequency converter 4 breakdown signals are connected with bucket type gauge 2 input ends by terminal 12, and bucket type gauge 2 output frequency converters 4 breakdown signals are connected with programmable controller 1 input end by terminal 1,2.
Embodiment 1.
The utility model system comprises following components: startup/stop button, programmable controller (PLC) or upper computer, frequency converter, motor etc.The flow that upper computer will be carried, communication form with industry transmission signal RS485 commonly used, transfer to the bucket type measuring instrument. the bucket type measuring instrument, according to the instant flow rate setting value, send the signal of DC4-20mA to frequency converter, frequency converter is according to the DC4-20mA signal of giving, and drive motor drives the conveyor hopper running, thereby finishes the conveying of material.With motor links to each other with conveyor hopper a rotary encoder arranged, the actual fed flow signal can be fed back to the bucket type measuring instrument, the bucket type measuring instrument is compared the actual flow value with the setting flow value, if the actual flow value is greater than setting flow value, reduce to give the control signal of frequency converter, otherwise, strengthen control signal, thereby form the closed-loop measuring control system.As shown in Figure 1
In material conveying process, indicator lamp is bright when startup/stop button is pressed, if high signal is arranged, the delivery duct above the expression conveyor hopper has material, and the bucket type measuring instrument just can be sent the DC4-20mA signal, the running of control driven by motor conveyor hopper.Otherwise, if no high signal then stops the conveyor hopper running.As low level signal (LOW=0), the delivery duct of expression below the conveyor hopper has material, then should stop convey materials, otherwise it is full to be blocked.If during no low level signal, the bucket type measuring instrument just can be sent the DC4-20mA signal and turn round for the frequency converter drive motor.Breakdown signal refers to that frequency converter passes to the breakdown signal of bucket type gauge.As Fig. 1-shown in Figure 2.
The cylinder feeder is work like this:
As shown in Figure 3.But the casing constant volume of cylinder feeder of the present invention also rotates by synchronous dynamo actuating spindle blade simultaneously, controls the material dosing feed by the rotating speed of Frequency Converter Control synchronous dynamo again.This device arranges mechanical seal ring between axle and disk, efficiently solve because of poorly sealed leakage material problem and the bearing that causes and hold problem tightly; The utility model blade adopts the tetrafluoro polythene material, and stronger hardness is arranged, and wear-resistant withstanding corrosion.Because interlobate volume is fixed, its aluminium oxide quality also is quantitative, so feed also is quantitative, because driving aluminium oxide, blade carries out blanking simultaneously, aluminium oxide is to dish out along the tangential direction of blade placement axis, the stirring of playing and the effect of shedding material are not evenly lumpd blanking more.
