Abstract

The utility model relates to a quantitative filling machine, which is in particular suitable for cosmetic, food and drinking industries that need quantitative filling. The quantitative filling machine comprises a shell, a control mechanism, a power and driving mechanism and a filling mechanism and is characterized in that the control mechanism consists of a micro single chip control circuit and a frequency control device; the filling machine consists of a filling pump and is powered by a stepping motor, while the filling pump consists of a pump body, a feeding gear, a shaft sleeve gasket and an end cover. An inlet point and an outlet point are arranged on the pump body while the pump body is separated into two disconnected parts by a feeding gear, and materials are delivered to the outlet passing through the gaps of the feeding gear; the utility model is characterized in that the utility model can adapts to various material, and the filling quantity can be adjusted flexibly, while the utility model can also be used in a large range and has high accuracy.

Description

Dosing filling machine

The utility model relates to a kind of dosing filling machine, is particularly useful for the industry that daily use chemicals, food and drink etc. need quantitative filling.

At present, domestic its measuring fixed amount mode of filling machine that is used for quantitative filling is basically nothing more than following several modes: plunger tpe and capacity formula, because the structure of this dual mode is limit, the adjusting of can amount is cumbersome and setting range is limited, filling accuracy is not high, complex structure cleans inconvenient, and wideless to the comformability of can medium kind.

The purpose of this utility model is to provide a kind of can amount can adjust, can adapt to multiple can medium, filling accuracy height flexibly and cleans dosing filling machine easily.

The utility model achieves the goal by adopting following scheme: control mechanism is made up of one chip microcomputer control circuit and frequency conversion adjuster, power adopts stepper motor, filling mechanism adopts filling pump, filling pump is by the pump housing, feeding gear, the axle sleeve pad, end cap constitutes, the pump housing is provided with the shape chamber of cross section and ingear feeding gear running-fit, both sides are provided with inlet point and the discharging opening that is communicated with the shape chamber, feeding gear places in the shape chamber, the tooth of gear mesh is divided into charging and discharging two parts that directly are not communicated with inlet point and discharging opening, and end cap is by being bolted on the pump housing two ends.

Owing to adopted technique scheme, material is brought to discharging opening on one side on one side by the feeding gear inter-lobe clearance that rotates from inlet point, and form certain negative pressure on one side at inlet point material attract to replenish is kept continuous can, therefore it to various types of materials as: aqueous, paste, pulpous state, oily and highly viscous property material, in addition, because inter-lobe clearance is changeless, it is quantitative that the moving tooth of revolution newly send volume of material, therefore the control system of being made up of one chip microcomputer and variable-frequency governor can be exported corresponding spike train easily according to the can amount, accurately control the rotating speed of filling pump and the purpose that revolution reaches quantitative filling, and the can amount is easy to adjust, scope is very wide, the precision height.

The utility model is further elaborated and has given embodiment below in conjunction with accompanying drawing:

Fig. 1 is the utility model example structure scheme drawing;

Fig. 2 is Figure 1A-A generalized section:

Fig. 3 is an embodiment tachometer generator scheme of installation.
