Technical field
The utility model relates to filling apparatus field, the unidirectional filling mechanism of especially a kind of antidrip for bottle placer.
Background technology
Filling liquid is widely used in the every profession and trades such as food, medical daily use chemicals, grease, can carry out filling to different high viscosity fluids.When filling head inserts by the container of filling liquid, the liquid outlet at filling exit place, filling lower end with take out negative tube product all in by container filling, in container, produce negative pressure, by filling exit, liquid is sucked in container, because the raffinate in filling head is more, in pouring process, filling head can produce water clock, and raffinate may blow back in bottle placer, meanwhile, the liquid in filling head can not arranged, and has reduced precision and the service life of filling head.
Summary of the invention

The utility model solves the technical scheme that its technical matters adopts: the unidirectional filling mechanism of a kind of antidrip for bottle placer, comprises filling body, mount pad, stopper rod, syringe needle and unidirectional liquid inlet; Described filling body upside is fixedly connected with mount pad, and mount pad is for fixedly mounting cylinder, and filling body downside is connected with syringe needle;
Described stopper rod comprise be arranged on top footstock, be arranged on middle part sealing axial region and be arranged on bottom cut-off portion; Lower end and the mutual butt of syringe needle of described cut-off portion; Described sealing axial region is through the upper opening of filling body; Described footstock is to be connected with cylinder rod; Between the upper end of described footstock and filling body, be provided with returning spring; Between described sealing axial region and filling body upper opening contact surface, be provided with seal ring; Between described syringe needle upper end and stopper rod contact surface, be provided with sealing rubber ring; Described syringe needle middle part is provided with press section;
Described unidirectional liquid inlet is arranged on filling body side surface, the Compress Spring that comprises spool and be connected with spool; The described Compress Spring other end is connected with filling body sidewall; Described filling body sidewall and unidirectional liquid inlet connectivity part are provided with polytetrafluoro pipe.
As preferred scheme, described filling body bottom is provided with syringe needle and reinforces fabricated section.
As preferred scheme, between described cylinder rod and stopper rod, be to be connected by screw.
As preferred scheme, described press section is rubber tube.
The beneficial effects of the utility model are: the unidirectional filling mechanism of a kind of antidrip for bottle placer, utilize and by the stopper rod of cylinder control, dropping liquid is opened and closed, the press section that syringe needle middle part arranges can the emptying syringe needle of actv. in remaining dropping liquid, antidrip is effective, the unidirectional liquid inlet that employing has one-way function prevents that liquid from flowing backwards and easy evacuation of liquid, and work efficiency is high.
