The utility model is implemented by following technical solution:
A kind of quantitative filling machine structure, it is characterized in that: comprise fluid reservoir, fluid reservoir has inlet, liquid outlet and liquid pumping hole, inlet is provided with the liquid feed valve of the unidirectional unlatching of cavity direction in fluid reservoir outward, liquid outlet is provided with the liquid valve of the interior unidirectional unlatching of cavity direction of fluid reservoir dorsad outward, be provided with piston in liquid pumping hole, piston is promoted by cylinder.
The quantitative filling machine structure of technique scheme, simple in structure, during work at first the piston in liquid pumping hole outwards pulled by cylinder, so form vacuum at the fluid reservoir inner chamber, liquid feed valve is opened, feed liquid is drawn into the fluid reservoir inner chamber from inlet, then cylinder pushing piston return, the feed liquid that is drawn into the fluid reservoir inner chamber is seen off from liquid outlet, this moment liquid feed valve close, liquid valve opens, periodical duty successively.Because the distance of the each pushing piston of cylinder is identical, so the feed liquid and the each feed liquid of seeing off from liquid outlet that are drawn into from inlet are quantitative at every turn, error is little, and pouring amount is accurate.
As preferably, inlet, liquid outlet and liquid pumping hole are mutually an angle of 90 degrees setting.
As preferably, liquid feed valve comprises valve body, spool, valve rod, flexible spring seat and quiet spring perch, valve body is provided with valve opening, and valve rod arranges along the valve opening axial direction is movable in valve opening, and the outside rod end of valve rod is connected with flexible spring seat, after passing quiet spring perch, the inboard rod end activity of valve rod is connected with spool, quiet spring perch is fixedly installed in valve opening, is provided with spring between the sound spring perch, under action of the spring, spool is blocked valve opening from the valve opening inboard, and the contact surface of spool and valve opening is the conical surface.
As preferably, liquid valve comprises valve body, spool, valve rod, flexible spring seat and quiet spring perch, valve body is provided with valve opening, and valve rod arranges along the valve opening axial direction is movable in valve opening, and the inboard rod end of valve rod is connected with flexible spring seat, the outside rod end activity of valve rod is connected with spool after passing quiet spring perch, quiet spring perch is fixedly installed in valve opening, is provided with spring between the sound spring perch, under action of the spring, spool is blocked valve opening outside valve opening, the contact surface of spool and valve opening is the conical surface.
As preferably, cylinder is the double end cylinder.After adopting the double end cylinder, the portable bar tail end of cylinder is connected with limiting stopper, by the position of adjusting limiting stopper on the cylinder portable bar, each pouring amount of conveniently adjusted filling machine structure.
