Specific embodiments
With reference to Fig. 1,2,3,4,5, a kind of with full-automatic whet a knife two-sidedly cut open seam machine, comprise base platform 8, base platform 8 is provided with electric machine support 11, at electric machine support 11 built with knife drive motor 2, knife drive motor 2 output shaft is equipped with blade 1, the two-sided seam machine that cuts open is equipped with front upper cover 12 and rear upper cover 20, in the side of electric machine support 11, base platform 8 is latter half of is equipped with grinding head mechanism; Described grinding head mechanism comprises two guide rails 7 be fixed on base platform, two guide rails 7 are equipped with guide rail platform 17, described guide rail platform 17 is connected with grinding wheel feed Driving Stepping Motor 6 with screw mandrel 18 by nut, bistrique angle cylinder 5 and rotatable platform 19 described guide rail platform be equipped with, bistrique drive motors 4 is fixed in rotatable platform 19, and bistrique drive motors 4 output shaft end is equipped with bistrique 3.
Guide rail 7 is equipped with feeding initial point optoelectronic switch 13, rotatable platform 19 is equipped with bistrique inclination angle and puts in place proximity switch 15, bistrique angle cylinder 5 is equipped with bistrique level and puts in place proximity switch 16.The closed proximity switch 9 that puts in place of upper cover after each installation one about rear upper cover 20 end, about rear upper cover 20 liang of side lower parts, after each installation one, upper cover opens the proximity switch 10 that puts in place.
Rear upper cover 20 is also divided into 2 half by left and right, after left and right after upper cover solenoid valves cylinder intake, pull rear upper cover 20 first to move down one section and turns to two avris and hold up.By the closed proximity switch 9 that puts in place of rear upper cover, detect cover plate closing and put in place; Cover plate is opened and is rotated to cocked position, opens by rear upper cover the proximity switch 10 that puts in place, and detection cover plate is opened put in place completely.After bistrique angle solenoid valves switches air inlet jack-up, the front portion of bistrique 3 reduces, rear portion raises, ensure that bistrique 3 and blade 1 define a fixing angle, this angle should be the sharpest angle ensureing blade 1, and ensure dieback, rotatable platform 19 is equipped with bistrique inclination angle and puts in place proximity switch 15, detect the anglec of rotation and put in place; For ensureing that bistrique turns back to horizontal level really, bistrique angle cylinder 5 is equipped with bistrique level and puts in place proximity switch 16, return after putting in place, provide signal, other mechanism just returns one by one.Grinding wheel feed Driving Stepping Motor 6 forward and backward, namely drives the forward and backward movement of whole grinding head mechanism, realizes cutting feeding.Guide rail 7 is equipped with feeding initial point optoelectronic switch 13, as feeding initial point sense switch, guarantees that the datum mark of each feeding is same location point.Knife drive motor 2 is AC servo motor, built-in 1000 line grating encoders, can ensure that the angle rotated is accurate.For ensureing the grinding adapting to difform blade 1, in the axle position, bottom of knife drive motor 2, a blade initial point optoelectronic switch 14 is installed, as the starting point angle reference of each anglec of rotation when whetting a knife.
Control method: for controlling the running of each motor in time, control system adopts two MCU(TMS320F28031 of TI company, U1 and U2), U1 with U2 is connected by PORT COM, U1 output connects knife drive motor by servo drive circuit, the input termination blade origin sensor of U1, sharpening switch and potentiometer, potentiometer realizes the speed governing of blade motor; U2 inputs termination display button panel, bistrique inclination angle puts proximity switch in place, bistrique level puts proximity switch in place, the closed proximity switch that puts in place of right back upper cover, the closed proximity switch that puts in place of left back upper cover, right back upper cover opens the proximity switch that puts in place, left back upper cover opens the proximity switch that puts in place, feeding origin sensor and potentiometer, U2 output is connected grinding wheel feed Driving Stepping Motor through one-way bus driver 74LS244 with drive circuit, and U2 output connects left back upper cover electromagnetic valve, right back upper cover electromagnetic valve, bistrique angle electromagnetic valve; U2 output connects bistrique drive motors through U3.For simplifying programming and ensureing driveability, bistrique drive motors adopts BLDC motor, IPM is driven by the special BLDC vector controlled chip U3 of Allegro, BLDC grinding head motor is driven to operate again, by the speed command of speed regulator potentiometer by the given U3 of U2, U3 automatic computing can ensure that bistrique drive motors operates in given speed.When needs are whetted a knife, after pressing sharpening switch, control system enters sharpening program: panel enters setting interface, select blade shapes (corner, hexagonal, anise, abnormity etc.), the amount of feeding, profiling etc., press again preserve key memory, next time again grinding time automatically directly can enter grinding.If do not need setup parameter, then press grinding and start key, control system first connects left and right rear upper cover electromagnetic valve, after cylinder intake pulls two pieces, upper cover 20 is opened, and the rear upper cover bottom after putting in place is opened the proximity switch 10 that puts in place and outputed signal, after MCU receives signal, export bistrique angle cylinder activation signal again, rotatable platform 19 is by bistrique angle cylinder 5 jack-up, and after putting in place, the bistrique inclination angle proximity switch 15 that puts in place sends signal.Simultaneously, blade 1 is according to the blade shapes of setting, according to grating encoder and the blade initial point optoelectronic switch 14 of 1000 lines, it is parallel with the plane of bistrique 3 to limit to be ground that MCU controls knife drive motor 2 rotating blade 1, after putting in place, control system is to knife drive motor 2 logical two phase electricities, and pinning blade 1 can not rotate.Bistrique 3 starts running, grinding wheel feed Driving Stepping Motor 6 controls the amount of feeding of grinding according to feeding initial point optoelectronic switch 13 simultaneously, after feeding grinding puts in place, bistrique 3 returns to initial point automatically, blade 1 rotates an angle again, after putting in place, bistrique 3 again feeding repeats grinding, a to the last limit grinding completes, bistrique drive motors 4 is out of service, grinding wheel feed Driving Stepping Motor 6 runs and allows grinding head mechanism fall back on origin position, feeding initial point optoelectronic switch 13 sends signal, MCU exports and controls bistrique angle cylinder power-off withdrawal, bistrique is horizontal, the bistrique level proximity switch 16 that puts in place sends signal, MCU exports and controls a left side, the power-off of right back upper cover electromagnetic valve, after two pieces, upper cover 20 gets back to closing position, the closed proximity switch 9 that puts in place of rear upper cover outputs signal, MCU drives buzzer rings, enter and cut open slit die formula, prompting can have been sewed.For the blade (as ellipse) of heterotype edge, even for ensureing edge stock removal, first manually can carry out profiling by the button on panel, namely feeding motor moves left and right, and blade motor also coordinates the anglec of rotation to follow, and resets several deciles of 360 degree, after completing, store-memory, more as previously mentioned, complete grinding.For circular shear blade, then simpler, blade, bistrique be opposite direction rotating simultaneously, can complete grinding at a high speed.
