2, button SB
1with alternating current contactor KM3, the uncap control step of circuit of its temperature control is as follows:
Step 1: press the button SB
1temperature controller KMw circuit is connected, and starts testing temperature, simultaneously alternating current contactor KM
3energising, KM
3normally closed contact disconnect, normally opened contact closure;
Step 2, SB closes a switch
2, at this moment alternating current contactor KM
3normally opened contact connected circuit connect, therefore alternating current contactor KM1 energising, seed-frying machine motor M
1forward, starts to fry material; Seed-frying machine motor M
1alternating current contactor KM when forward
1normally opened contact closure, reducing motor M
2energising is rotated, and while turning an angle, crank turns axle impact stroke switch S T
1(seeing the label 10 in Fig. 1), travel switch ST
1normally closed point disconnect, reducing motor M
2(seeing the label 19 in Fig. 2) dead electricity and stopping operating;
Step 3, in the time that in drum frying pot, seed material fries, kettle temperature is elevated to the design temperature of temperature sensor 4, the normally closed contact of temperature controller KMw disconnects, at this moment alternating current contactor KM
3dead electricity, KM
3closed normally opened contact disconnects, the normally closed contact closure of disconnection, now switch S B
2still connecting therefore alternating current contactor KM
1power-off, KM
2energising, seed-frying machine motor M
1discharging is carried out in reversion.At this moment alternating current contactor KM
1normal battle disconnect, alternating current contactor KM
2normal battle closed, reducing motor M
2obtain electric beginning again and rotate, after rotating, drive crank to turn the normally closed contact ST of axle disengaging travel switch
1, make its normally closed contact ST
1recovering closure is that next cycle operation is ready; Reducing motor M
2drive crank to turn axle and be rotated further and promote to turn axle push rod sealing pot cover is opened and carried out discharging, pot cover is opened rear reducing motor and is rotated further, when crank turn axle disengaging turn axle push rod after impact stroke switch S T
2when the normally opened contact of (seeing the label 9 in Fig. 1), reducing motor M
2stop operating;
Step 4, after in pot, seed material unsnatches, pull manual lever by pot cover closure, press the button SB1, temperature controller KMw switches on again, seed-frying machine motor M
1forward is fried material;
Step 5, according to cocycle, just can complete and pull manual lever 5 and close the door reinforcedly, fry rear automatic lid closing/opening discharging, realized the practical function of keeping an eye on seed-frying machine without people.
Principle of work: the Horizontal roll fried dish pan of pot cover of the present invention and pot cover opening and closing device and seed-frying machine supports the use, pot cover 1 is under the oblique pulling effect of gravity and passive connecting rod 2, the pot that can be close to all the time drum frying pot 13 is mouthful upper, and rotates and rotate with drum frying pot 13.Two cover hinge four-bar mechanisms act on pot cover 1 both sides, and to keep the balance of pot cover 1, the swing while simultaneously utilizing the flexible feature of hinge four-bar mechanism can make again pot cover 1 rotate with cylinder pot mouth swings.In the time that frying, seed material pulls manual lever 5 with hand, transmission shaft 16 rotates thereupon, transmission shaft 16 drives drive connecting rod 7 to rotate, drive connecting rod 7 promotes intermediate connecting rod 6, intermediate connecting rod 6 promotes again passive connecting rod 2 makes passive connecting rod 2 rotate around connecting rod rest 8 upper end bearing pins, because pot cover 1 is mounted on two passive connecting rods 2 by pot cover hinge 14, so passive connecting rod 2 drives pot cover 1 to leave home position and realizes pot cover 1 and open while rotation, in the time that turning an angle, drive connecting rod 7 arrives the dead-centre position of hinge four-bar mechanism, now under the effect of positive stop, drive connecting rod 7 can not be rotated again, utilize four-bar mechanism " dead point dieback " principle, pot cover 1 is opened and can be hovered over this position.In the time that discharging completes, pull manual lever by above-mentioned opposite direction and can realize and close pot cover.In the time that seed material fries, temperature sensor 4 is by the circuit communication of uncapping of the temperature control in signal wire and electric control box 11, start reducing motor 19 simultaneously, reducing motor 19 output shafts drive crank to turn axle 18 and rotate, crank turns axle and promotes to turn axle push rod 17, transmission shaft 16 rotates thereupon, transmission shaft 16 drives drive connecting rod 7 to rotate, and drive connecting rod 7 promotes intermediate connecting rod 6, and intermediate connecting rod 6 promotes again passive connecting rod 2 makes passive connecting rod 2 rotate pot cover 1 is opened around connecting rod rest 8 upper end bearing pins.Now can manually open and close pot cover 1 in order not affect, opening pot cover 1 rear crank turns axle 18 and is rotated further and makes crank to turn axle 18 to avoid and turn after axle push rod 17, by travel switch 9,10, reducing motor 19 is stopped operating, realization is automatically opened pot cover 1 and is completed discharging thus, does not affect again the practical function of manual switching pot cover 1 simultaneously.
