The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the disconnected paper tinsel of aluminium foil mill of the present invention is cut the control system do further explain.
As shown in the figure, the disconnected paper tinsel of aluminium foil mill of the present invention is cut the control system and is comprised source of the gas 1 and drive cylinder 8 that source of the gas connects the epicoele pipeline 3 and cavity of resorption pipeline 4 that drives cylinder respectively through two outlets through No. one two position switching valve 4, between the two-way pipeline, switches; Source of the gas 1 descends through epicoele pipeline cylinder piston when driving cylinder 8 epicoele air inlets and carries out shear action; Source of the gas 1 lifts disconnected paper tinsel through the cylinder piston rising when driving cylinder 8 cavity of resorption air inlets of cavity of resorption pipeline and cuts; Epicoele pipeline 3 is divided into forward and backward two sections by No. two two position switching valves 5; The leading portion of epicoele pipeline 3 is connected between the inlet of an outlet and No. two two position switching valves 5 of No. one two position switching valve 4, and the back segment of epicoele pipeline 3 is connected the output of No. two two position switching valves 5 and drives between cylinder 8 epicoeles; Another inlet of said No. two two position switching valves 5 is connected with source of the gas 1 through a pressure regulator valve 6; Conducting between 5 pairs of two inlets of No. two two position switching valves and the output is switched.No. two reversal valves 5 and drive between cylinder 8 epicoeles and also be provided with an one-way throttle valve 7.The exit of source of the gas 1 also is provided with accumulator 9.Also be provided with the spring 10 that applies downward elastic force to piston in the epicoele of driving cylinder.
Operation principle of the present invention is following:
As shown in Figure 2, when milling train during at inspecting state, the gas in the source of the gas, makes disconnected paper tinsel cut and lifts in addition mechanical position limitation to the cavity of resorption air inlet that drives cylinder 8 through No. one two position switching valve 4; The pressure regulator valve that is connected simultaneously between source of the gas and No. two two position switching valves also has gas to send into, but when the gas of pressure regulator valve up moves to No. two two position switching valves, because No. two two position switching valves are in the left side station, so by, this road is obstructed; The gas that drives upper chamber of air cylinder is compressed, down move along one-way throttle valve, when gas communication to No. two two position switching valves by, this road also is obstructed, but can make the pipeline gassy that drives between upper chamber of air cylinder and No. two two position switching valves; Not only guaranteed operator safety thus, and cut further work for disconnected paper tinsel and prepare.
As shown in Figure 3, when the disconnected paper tinsel of entering mill milling was cut SBR, source of the gas gas was sent to the cavity of resorption that has of cylinder, and the paper tinsel that will break is cut and lifted; The pressure regulator valve that is connected simultaneously between source of the gas and No. two two position switching valves also has gas to send into; This moment, No. two two position switching valves were in the right side station; Therefore source of the gas also with drive the upper chamber of air cylinder conducting, through the adjustment pressure regulator valve, the epicoele gas pressure turned down making epicoele aerodynamic force and the addition of camber of spring power less than cavity of resorption aerodynamic force; Therefore be not enough to promote disconnected paper tinsel and cut, keep disconnected paper tinsel and cut and be failure to actuate; But drive the upper chamber of air cylinder gassy this moment, has certain back pressure, cuts further work for disconnected paper tinsel and prepare.
As shown in Figure 4, disconnected paper tinsel is cut when being in user mode, and No. one two position switching valve and No. two two position switching valves switch simultaneously; Source of the gas and the complete conducting of driving upper chamber of air cylinder; Have back pressure owing to drive upper chamber of air cylinder itself, therefore make bleed pressure export cylinder rapidly to, thereby the paper tinsel that will break is fast cut release.
In addition; Because the compressibility of gas, drive upper chamber of air cylinder gas and promote piston and eliminate cylinder self friction power and also need the time, in upper chamber of air cylinder, increase spring after; Camber of spring power is far longer than Pneumatic Cylinder with Friction, therefore can further improve movement response speed.
