Supercharging measuring cup type metering filling device
Technical field
The utility model relates to a kind of supercharging measuring cup type metering filling device, is suitable for the metering and the can of liquid article.
Background technology
At present the filling apparatus in pharmacy and food, beverage industries has a kind of measuring cup type metering filling device, its structure is simpler, practical, weak point is to rely on the deadweight of liquid to flow automatically in the process of can, the speed of can is slow, because liquid has surface tension, filling exit may leave the residual drop that weight does not wait at last, influences filling accuracy.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of filling speed is fast, work efficiency is high, accurate measurement, structural principle advanced person's supercharging measuring cup type metering filling device.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of supercharging measuring cup type metering filling device comprises the measuring cup type metering filling parts, and it is characterized in that has the air pressure parts on the measuring cup type metering filling parts.
The air pressure parts comprise with compressed gas and being connected, down with the pipeline that overflow pipe is connected, the centre is provided with valve of measuring cup type metering filling parts, the rear portion of pipeline junction is provided with valve on the overflow pipe of measuring cup type metering filling parts.
On the silicone tube between measuring cup and the hoop valve, the metering regulating control is arranged.
Valve is Electronic Valve or electromagnetic valve or pneumatic diaphragm valve or electronic diaphragm valve.
The beneficial effects of the utility model are the pressure-producing parts that connect a vapour-pressure type on existing measuring cup type metering filling device, and reasonable in design, technology are simple, the speed of low cost of manufacture, can is fast, work efficiency is high, the metering is more accurate.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises measuring cup type metering filling parts 1, and air pressure parts 2 are arranged on measuring cup type metering filling parts 1.Measuring cup type metering filling parts 1 generally by frame 6 and be contained in the fluid flow tube 7 that is communicated with liquid phase to be installed, valve 4, measuring cup 8, silicone tube 9 on the frame 6, bind round valve 10, overflow pipe 3 is formed, measuring cup 8 is the volumetric metering device, the open and close of hoop valve 10 control silicone tubes 9, silicone tube 9 is a flexible pipe, during hoop valve 10 bandings, silicone tube 9 cuts out, otherwise opens.Its control mechanism can be compressed-air controlled, hydraulic pressure or electrical equipment, close reliably, move freely as long as reach silicone tube 9.Silicone tube 9 and hoop valve 10 also can be made up of pipeline and valve, and the former is more simple and practical.During work, valve 4 in the fluid flow tube 7 is opened, hoop valve 10 on the silicone tube 9 cuts out, liquid flows in the measuring cup 8 through fluid flow tube 7, behind full of liquid in the measuring cup 8, metering is finished, and excess liquid is discharged to reclaim through overflow pipe 3 again and entered in the primary liquid groove jar, because the control of valve 4, the liquid that flows in the overflow pipe 3 is few, and at this moment, the valve 4 in the fluid flow tube 7 cuts out, hoop valve 10 is opened, liquid quantitative flows in the bottle from measuring cup 8 automatically, finishes the can of a liquid, and the valve in the fluid flow tube 74 is opened then, hoop valve 10 cuts out, and circulation works without cessation so repeatedly.In this pouring process, mainly rely on the deadweight in the measuring cup 8 to fill by gravity, the speed of can is slow, because liquid has surface tension, liquid feeding mouth is general residual drop, not only influences the precision (exacting requirements being arranged in pharmaceuticals industry) of metering but also cause unnecessary waste.The utility model is set up air pressure parts 2 on the basis of above-mentioned technology, it is connected with compressed gas by last, be connected with the overflow pipe 3 of measuring cup type metering filling parts 1 down, there is the pipeline 5 of valve 4 centre and on the overflow pipe 3 of measuring cup type metering filling parts 1, the valve 4 that the rear portion of pipeline 5 junctions is provided with is formed, in the 1 beginning can of measuring cup type metering filling parts, valve 4 on the overflow pipe 3 cuts out, valve 4 in the pipeline 5 is opened, compressed gas enters in the measuring cup 8, under the effect of compressed gas, descending fast under the liquid air pressure in the measuring cup 8 and the combined action of deadweight, inject in the container of lower end.Because pressure strengthens, flow velocity is accelerated, the table power tension failure of liquid, the residual dropping liquid of liquid feeding mouth has not existed.After the liquid in the measuring cup 8 flow to end, the valve 4 on the pipeline 5 cut out, and the valve 4 on the overflow pipe 3 is opened, and cooperates measuring cup type metering filling parts 1 feed liquor ... circulate so repeatedly, go round and begin again.On the silicone tube 9 between measuring cup 8 and the hoop valve 10, metering regulating control 11 is arranged, change the interior pipe volume of silicone tube 9, realize the fine setting of measuring cup 8 meterings with it.Valve 4 can be Electronic Valve or electromagnetic valve or pneumatic diaphragm valve or electronic diaphragm valve, and all control through each class component can realize that the valve of automatic shutter can.The pressure of the air pressure parts 2 of this pressure measuring cup type metering filling device is looked difference, the liquid difference of container, and its pressure is difference to some extent, can be suitably big than bottle type container as soft bag.When this device was used for the can medicine, pressurized air was pure air or unreactable gas.Because pressure strengthens, flow velocity is accelerated during can, and residual dropping liquid has not existed, thereby can work efficiency height, and it is more accurate to measure.
