Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
On the basis of the structure of existing negative-pressure air-suction control setup, the present invention is newly-increased malleation blower mechanism, this malleation blower mechanism is when negative-pressure air-suction passage turns off, negative-pressure air-suction passage to negative-pressure air-suction mouth 8 place provides malleation air-flow, to offset negative pressure residual in negative-pressure air-suction passage, thus the slightly not smooth problem of the first electromagnetic valve 9 or cylinder 1 action can be solved, also more effectively control the first electromagnetic valve 9 in time and drive cylinder 1 to complete adhesive release movement.
As shown in Figure 4, malleation blower mechanism comprises malleation blowing mouth 10, and malleation blowing mouth 10 is opened on air draught valve body 7, relative with negative-pressure air-suction mouth 8.In the present embodiment, the direction of malleation blowing mouth 10 faces negative-pressure air-suction mouth 8, so the malleation air-flow of malleation blowing mouth 10 blowout and the negative-pressure air-flow at negative-pressure air-suction mouth 8 place, just to mixing, are convenient to offset negative pressure residual in negative-pressure air-suction passage in time, effectively.Obviously, the direction of malleation blowing mouth 10 is not limited to and faces negative-pressure air-suction mouth 8, can also tiltedly facing to negative-pressure air-suction mouth 8, even can not with negative-pressure air-suction mouth 8 just to or tiltedly right, as long as while negative-pressure air-suction passage turns off, can ensure to provide malleation air-flow in time, offset negative pressure residual in negative-pressure air-suction passage.But, the direction of malleation blowing mouth 10 is arranged to negative-pressure air-suction mouth 8 just to also have a benefit be: the malleation air-flow that malleation blowing mouth 10 blows out can blow out the flue dust in the negative-pressure air-suction passage at negative-pressure air-suction mouth 8 place in time, realizes self-cleaning function.
As shown in Figure 5, malleation blower mechanism also comprises the device for controlling malleation blowing mouth 10 pressurized air A break-make.In the present embodiment, what this device adopted is that the second electromagnetic valve 11, second electromagnetic valve 11 is connected on pressurized air A, and connects malleation blowing mouth 10 by pipeline.The control coil of the second electromagnetic valve 11 can be in parallel with the control coil of the first electromagnetic valve 9, by external control action simultaneously, also can by manually controlling the control coil of the second electromagnetic valve 11 and the control coil of the first electromagnetic valve 9, as long as synchronization action both ensureing.
In the various embodiments described above, what the first electromagnetic valve 9 adopted is two-position-five-way solenoid valve, and the second electromagnetic valve 11 can adopt two-position two-way solenoid valve (as shown in Figure 5), also can adopt two-position three way magnetic valve, but be not limited thereto.
As shown in Figure 4, Figure 5, when the first electromagnetic valve 9 and the second electromagnetic valve 11 not electric time, pressurized air A is from the second gas interface 4 air inlet of cylinder 1, piston 2 drives valve plug 5 to retract, negative pressure mouth 6 is communicated with negative-pressure air-suction mouth 8 forms negative-pressure air-suction passage in air draught valve body 7, label paper under the effect of negative pressure by under suction.When the first electromagnetic valve 9 and the second electromagnetic valve 11 obtain electric, pressurized air A is from the first gas interface 3 air inlet of cylinder 1, and piston 2 drives valve plug 5 to eject, and turns off negative-pressure air-suction passage, remains negative pressure in the negative-pressure air-suction passage at negative-pressure air-suction mouth 8 place.While negative-pressure air-suction passage turns off, the pressurized air A exported by the second electromagnetic valve 11 blows out from malleation blowing mouth 10 by the present invention, and form malleation air-flow, this malleation air-flow just can offset the residual negative pressure of negative-pressure air-suction passage.Simultaneously, because this malleation air-flow is blown into air draught valve body 7 by malleation blowing mouth 10, and blow out from negative-pressure air-suction mouth 8, therefore also can as the clean air pressure of negative-pressure air-suction passage, blowout flue dust, prevents from adsorbing flue dust in the negative-pressure air-suction passage because of air draught valve body 7 and the fault such as piston 2 action that produces is smooth, valve plug 5 is poorly sealed.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
