Description
Technical field
The utility model relates to a kind of screw type sub packaging machine, relates in particular to a kind of screw type sub packaging machine suction control device.
Background technology
Fast development along with medical industry, in the production that is applied to powder injection formulation that screw type sub packaging machine is more prevalent, due to screw type sub packaging machine, will to have packing dosage than screw filling machine high, consume little, be not subject to the characteristics such as medicinal powder crystalline form restriction, to little with those proportions, bulky medicinal powder also can carry out packing, so screw type sub packaging machine is widely used in current preparation production.
In the production process of screw type sub packaging machine, after medicine bottle adds and installs pulvis, need medicine feeding bottle to add and press bottle stopper, the mode that button plug mechanism adopts vacuum suction from bottle stopper is drawn on the match track, and then be installed on medicine bottle, then disconnecting the air-breathing medicine bottle that installs bottle stopper that allows is delivered on the catch pan of back, then detaining plug device gets back to again lower match track and goes out to open and air-breathing bottle stopper is drawn, so repeat this button plug process, controlling air-breathing and key device that die in this process is air suction valve, common air suction valve adopts the physical construction of aluminum alloy to make, the air suction valve of aluminum alloy system reaches air-breathing and operation that die by the mechanical movement of synchronizeing with button plug mechanism, in the continuous air-breathing process with dying, mutual frictional loss between metal device is serious, the air suction valve that has caused aluminum alloy system is deformed damaged very easily, cause the generation of gas leak phenomenon, from negative pressure when carrying out sucking action, bottle stopper can't be held not, cause bottle stopper very easily to drop, can't complete normal button plug action.The air suction valve of aluminum alloy system needs often to change, and the dismounting difficulty, and its manufacturing cost costliness, greatly increased and safeguarded the cost of changing simultaneously.
The utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is improved prior art, and a kind of screw type sub packaging machine suction control device is provided, and the air suction valve that solves screw type sub packaging machine in current technology is short service life, the problem that maintenance cost is high.
For solving above technical matters, the technical solution of the utility model is:
A kind of screw type sub packaging machine suction control device, comprise electromagnetic valve, solid-state relay and photoelectric monitor device, the photoelectric monitor device is arranged on the button plug device, monitoring is drawn bottle stopper and is withheld the process formation photoelectricity make-and-break signal of bottle stopper, by circuit, the photoelectricity make-and-break signal is passed to solid-state relay, the electric control signal that solid-state relay converts the photoelectricity make-and-break signal to rotating passes to electromagnetic valve, electromagnetic valve is connected on aspirate tube, is controlled the opening and closing of gas circuit by the electric control signal of rotating.Solid-state relay is the contactless electronic beam switch with isolation features, machinery-free contact component in switching process, so solid-state relay is except having the function the same with electromagnetic relay, also there is the decision circuit compatibility, the anti-anti-physical shock of shaking, installation site is unrestricted, has good moistureproof and mildewproof Corrosion Protection, explosion-proof and prevent that the performance aspect ozone pollution is also splendid, horsepower input is little, highly sensitive, and power ratio control is little, electromagnetic compatibility is good, and noise hangs down and the frequency of operation high.Airtight chamber is arranged in electromagnetic valve, have through hole at diverse location, each hole connects different siphunculus, in the middle of chamber, it is piston, two sides is two blocks of electromagnet, which side the magnet coil energising valve body of which face will attracted to, open or close different deflation holes by the movement of control valve body, and induction opening is often opened, gas will enter different freeing pipes, then by the pressure of gas, promotes the piston of cylinder, and piston drives again piston rod, piston rod driving mechanical device, just controlled mechanical movement by the current switching of controlling electromagnet like this.The long service life of solid-state relay, electromagnetic valve, good operation stability, the cost of parts is low simultaneously, greatly reduces the expense of maintenance.
Further, the photoelectric monitor device comprises photoelectric switch and disk, photoelectric switch is fixed on frame, disk is fixed in the rotating shaft of buckleing plug device and is driven and done rotation radially by rotating shaft, described disk has a breach, photoelectric switch is right against the edge of disk, and when disk rotates, the card of disk and breach alternate cycle form the photoelectricity make-and-break signal by photoelectric switch.Disk is along with buckleing the plug device rotation, the button plug device at lower match track everywhere in ventilation absorption state, bottle stopper is held, now photoelectric switch is right against the card of disk, the signal that offers solid-state relay is aeration status, then detain plug device in rotary moving, disk is synchronously more with in rotary moving, but now photoelectric switch still detects or the card of disk, when the button plug device is in rotary moving, to the medicine bottle mouth position, bottle stopper is buckled while being pressed into the medicine bottle mouth, now disc rotary is to its breach over against photoelectric switch, photoelectric switch is without monitoring result, offer the signal that solid-state relay is died, solid-state relay drives electromagnetic valve oppositely to operate the cut-out gas circuit, make the button plug device separate with bottle stopper, periodically repeat to appeal operation, can allow and detain the plug device smooth operation.
Compared with prior art, the utility model advantage is:
Screw type sub packaging machine suction control device described in the utility model adopts electromagnetic valve to replace the air suction valve of traditional aluminum alloy system, greatly reduce the cost of operating maintenance, electromagnetic valve and solid-state relay are subject to extraneous interference little simultaneously, good operation stability, long service life, reduced the frequency of operating maintenance, time saving and energy saving; And the utility model is simple in structure, convenient disassembly, arbitrary parts go wrong and can easily change, without the whole suction means of dismounting.
