Background

At present, a ventilation device of a vacuum feeding machine is mostly in a mode of connecting an air-intercepting valve by using an air cylinder, a piston in the air cylinder drives a silica gel plug in the air-intercepting valve to reciprocate, and when the air exchange and the material suction are needed, a piston rod drives the silica gel plug to be far away from a ventilation port along a valve body, so that an air suction port can suck air from the ventilation port, the negative pressure of a material suction port disappears, and the air exchange and the material discharge are realized; when the materials need to be sucked, the piston rod pushes the silica gel plug to move along the valve body and block the air vent, so that the air suction port can only suck air from the suction port, the suction port generates a large negative pressure, and the materials are sucked.

Because the induction port is continuously bled when the silica gel end cap moves, there is negative pressure in the valve body continuously, and it is great that the scavenge port seals to be the negative pressure, and the scavenge port is opened the back negative pressure and is less, so the silica gel end cap all can receive the negative pressure resistance when crossing the induction port and moving to the scavenge port and when crossing the induction port and keeping away from the scavenge port. Meanwhile, as the dust in the environment of a common workshop is more, the silica gel plug has a longer stroke in the reciprocating motion in the valve, the inner wall of the valve body is continuously rubbed, the dust is easily adhered and dyed, the moving resistance of the silica gel plug is increased, and the phenomenon that the plug and the air-intercepting valve body are locked and cannot move can be caused finally. Because equipment is generally installed in the top of jar body, highly great again, operating personnel often climbs and climbs down and maintains this problem, and influences production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the silica gel end cap that prior art exists and crossing the induction port when removing to the scavenge port and when keeping away from the scavenge port, the silica gel end cap all can receive negative pressure resistance's problem and because general workshop environment dust is more, the silica gel end cap is in valve reciprocating motion, easily glue the dust of dying, also can make the removal resistance increase of silica gel end cap, the phenomenon of locking unable motion between end cap and cut-off valve body can appear finally, again because equipment is generally installed in the top of the jar body, it is highly great, operating personnel often climbs and climbs down to maintain this problem, influence production efficiency's problem, a vacuum suction machine and cut-off valve thereof are provided, the negative pressure resistance that receives when the valve leaf of this cut-off valve removes can be ignored almost, the stroke is extremely short when the valve leaf moves radially, the dust of difficult sticking to dying, can reduce the probability of the phenomenon that appears locking unable motion between end cap and the cut-off valve body, reduce operating personnel's maintenance frequency, and improve production efficiency.

When the air shutoff valve is used, if a vacuum suction machine needs to ventilate and discharge materials, the valve blade 2 is driven to move in the radial direction of the valve body 1, translation or rotation can be achieved, the valve blade 2 leaves the ventilation port 3, so that the valve blade 2 can remove the blockage ventilation port 3 of the ventilation port 3 and is an opening arranged at one end of the valve body 1, the other parts except the opening at the end of the valve body 1 are solid, and a circular plate provided with the ventilation port 3 can be installed at one end of the valve body 1 through a screw in actual operation. At the moment, the air flow can pass through the air exchange port 3, the air suction port 5 does not independently suck air from the material suction port 4, but simultaneously sucks air from the material suction port 4 and the air exchange port 3, the negative pressure generated in the material suction device is reduced at a high speed and is not enough to suck the materials, namely, the material suction device starts to discharge the materials.

If the vacuum tube suction machine needs to suck materials, the valve blade 2 is driven to move in the radial direction of the valve body 1, and can move horizontally or rotate, and the valve blade 2 moves to cover the scavenging port 3, so that the valve blade 2 seals the scavenging port 3. At this moment, the air current can only pass through from inhaling material mouth 4, and air suction port 5 can only inhale from inhaling material mouth 4, and then makes the material suction device who is connected with inhaling material mouth 4 produce the negative pressure and absorb the material. When the material is sucked, the valve blade 2 is driven to open the air exchange port 3, the air exchange and material discharge process is started, and the reciprocating circulation operation is carried out.

Can know through the removal of the blowing of taking a breath and inhaling material in-process valve leaf 2 above-mentioned, compare in traditional silica gel end cap along the axis removal of valve body 1 in order to open the mode of sealing scavenge port 3, the utility model provides a scavenge valve is at the radial removal of valve body 1, no matter rotate or slide, its moving direction all is perpendicular with the direction of negative pressure force, and the negative pressure resistance that receives when valve leaf 2 removes can be neglected almost. Compare in the removal of silica gel end cap along the axis, the stroke is extremely short when valve leaf 2 radially moves to only can with the friction of the valve body 1 end wall part of the end of scavenge port 3 place, the valve body 1 position that contacts is less at the removal in-process promptly, is difficult for the adhesive dust, can reduce the probability that appears locking unable motion's phenomenon between end cap and the valve body 1 that cuts off the wind phenomenon, reduces operating personnel's maintenance frequency, improves production efficiency.

In the present embodiment, the valve vane 2 is rotatably provided at the transfer port 3 to close or open the transfer port 3 by rotation, and the rotation axis of the valve vane 2 is parallel to the axial direction of the valve body 1.

When the ventilation port 3 needs to be opened, the valve leaf 2 rotates away from the ventilation port 3, and the valve leaf 2 releases the sealing of the ventilation port 3, namely the ventilation port 3 is opened. When the air exchange port 3 needs to be closed, the valve blade 2 is rotated to be close to the air exchange port 3 until the air exchange port 3 is completely covered, and the air exchange port 3 is closed.

In the present embodiment, the damper includes a motor 6 for driving the valve blade 2 to rotate, and one end surface of the valve blade 2 is connected to an output shaft 7 of the motor 6.
