Fig. 1 is the scheme drawing of one of the utility model embodiment;

Fig. 2 is the state of kinematic motion scheme drawing of Fig. 1 embodiment.

According to accompanying drawing the utility model is done detailed explanation below:

As shown in Figure 1, the bottle placer body comprises valve body 19 and column 13, hopper 1 is housed above valve body, the hopper upper half part is made circle or square tube shape, the lower portion dwindles by a certain percentage, shape such as funnel, the hopper discharging opening docks mutually with valve body upper end spool bore, and its connection mode can adopt welding, flange to connect or be threaded.Valve body 19 has the coaxial spool bore of two different-diameters, up-small and down-big, communicating with the big valve core hole of valve body in the both sides on valve body top is provided with inlet opening 16 and fluid hole 6, and fluid hole is last, and inlet opening is down, the horizontal center line in two holes differs from the height in an aperture mutually, the offering the position and should guarantee when spool lower piston 5 operation downwards, can all open of two holes, lower piston 5 is when upwards operation puts in place, two holes all can be sealed so that lower piston 5 be in operation can be sequentially with two hole open and closes.

This routine spool is to be made of three pistons that are connected as a single entity, it wherein between upper piston 2 and the middle piston 4 one section quarter butt 3, change the length of quarter butt 3 and the can amount that diameter can be regulated granular solids 17 or liquid, the small valve core hole bearing fit on the external diameter of upper piston 2 and middle piston 4 and valve body top, the external diameter of lower piston 5 matches with the big valve core hole of valve body, on the valve body, the inside face of bottom spool bore respectively with spool on, the outside face of lower piston constitutes sealing surface, for guaranteeing the leak free reliability, this example also has additional rubber seal 18 in the upper end of upper piston 2 and the lower end of lower piston 5,15.

Valve body 19 is vertically mounted on the upper end of circular hollow column 13, the upper end of column has the step of a band center hole, suspension column is a base, drive link 12 is arranged in the column hollow body, the upper end of drive link is passed center hole and is connected with the lower surface of valve body lower piston 5, the drive link lower end is connected with lever 10 as operating mechanism, be provided with pressure spring 14 in the valve cavity of lower piston 5 belows, pressure spring is through on the drive link 12, its upper end is bearing on the lower surface of lower piston 5, and the other end is bearing on the step of column upper end.

The excircle in column 13 stage casings be provided with can upper and lower mobile adjusting round platform, device has carriage 9 on the round platform, carriage shown in this example is an arm shape structure, it is the center of circle with the center of column 13, can have the arm that at least more than one stretches out, carriage is by the circular hole of center-side and the external diameter bearing fit of column 13.Carriage is fixed on the column, and can holds in the palm parallel rotation on the round platform of column, the setting height(from bottom) of carriage on column can reach by regulating round platform, and round platform is fixing on column with screw.The bracket arm end is drilled with the circular hole parallel with the column line of centers, the cylinder bearing fit of circular hole and pallet 8 bottoms, be installed with pressure spring on the cylinder, the one end bearing is in the tray bottom, the other end is bearing in the frame arm end, can place containers 7 such as bottle, jar on the pallet, fluid hole 6 pipelines on the valve body are bent downwardly the top that reaches pallet, can join with vessel port.Pallet 9 also can be made into multiple patterns such as disc, semicircle dish type, its structure is identical with arm shape structure with connecting mode, as carriage mono-arm being changed into big disk around the column center of circle, five equilibrium bores a plurality of holes on the surrounding edge of dish, mix pallet, promptly constitute the disc type carriage, to satisfy different production needs.

Operating mechanism 10 is a leverage, the supporting-point of lever is located on the base of column below, the column bottom has the slotted hole of two mutual break-through, one end of lever passes across column and flexibly connects as the short column of supporting-point from the hole, lever is drilled with the hole corresponding to the midline of drive link 12, by screw lever and drive link are fixed, be provided with tension spring 11 between the operating side of lever and column, operating mechanism will be delivered to the position by the pulling force of spring 11 and the tension force of spring 14 on the spool.

When valve was in closed condition, upper piston 2 extend in the hopper 1, and middle piston closes spool bore 4 this moments, and lower piston 5 is with inlet opening 16 and fluid hole 6 sealings, and the inviscid granular solids 17 in the hopper 1 flows to and be filled with the space at quarter butt 3 places, upper piston below.When pressing the lever of operating mechanism 10 under (or stepping on) with hand (or pin), whole spool moves downward, granular solids is quantitatively brought into spool bore by spool upper piston 2, piston motion state as Fig. 2, simultaneously, moving downward of lower piston 5 makes fluid hole 6 and inlet opening 16 be in opening, and the liquid that flows into from inlet opening is with after the granular solids the spool bore mixes, in fluid hole is drained into container 7.When unclamping lever, spool is upward movement under the effect of pressure spring 14 and tension spring 11, lower piston 5 is closed inlet opening and fluid hole successively, and middle piston 4 is closed spool bore, extends into hopper 1 on the upper piston 2, expose quarter butt 3, granular solids is full of quarter butt space partly again, and to pressing down, the spring of tray bottom shrinks with the container on the pallet 87, can take out container, change new container.And so forth, reach the purpose of quantitative filling.

To the mixing quantitative filling of two kinds of different components liquid, only needing to set up a rubber seal on middle piston 4 can reach.

Inlet opening 16 on the cancellation valve body changes the quarter butt between spool upper piston and the middle piston into hollow tubular, opens the hole on it, can realize liquid quantitative filling in the hopper 1.

The dosing filling machine that proposes according to the utility model, solved the mixing filling problem in food, the beverage production process, sanitary index and the product quality of food, beverage have been improved, improved operating efficiency, alleviated workman's labour intensity, complete machine structure is simple, easy to operate, according to different can things, also can be made into manually and motor-driven multiple pattern, have bigger practical value.
