Abstract

The utility model provides a metering structure for powder conveying, which is especially designed for increasing the metering accuracy of powder during conveying. The metering structure comprises a stand, wherein two separated storage barrels are arranged on the surface of the stand and are respectively used for storing different powders, and gear motors arranged on the tops of the storage barrels drive inner stirring screws to constantly stir the stored powder so as to keep the powder to be unconsolidated and to prevent the powder from being conglomerated into balls; funneled discharge holes are formed on the lower parts of the storage barrels and are connected with a vibratory inline feeder under the stand, the vibratory inline feeder has the function of controllable feeding with multisection vibration frequency, the discharge pipe is made from transparent acryl materials, and the discharge end of the discharge pipe is connected with a metering cylinder by laid pipes. As a spiral feeding shaft is not arranged in the discharge pipe of the vibratory inline feeder, the powder can fill up the discharge pipe and fall into the metering cylinder according to the amplitude of the vibration frequency of the discharge pipe, therefore, the discharge amount of the powder can be excessively accurately controlled.

Description

The powder conveying measurement structure

Technical field

The utility model provides a kind of powder conveying measurement structure, mainly be to replace known motor transmission feeder with the dead-beat vibration feeder, utilize the shaking amplitude control frequently and making in the unrestrained hopper of powder discharging accurately of its discharge nozzle of its vibration, thus the screw feeding axle center that can effectively solve known motor transmission feeder easily gets stuck, bleed shortcomings such as the discharging that may cause is not accurate.

Background technology

General multiple powder mixture operation, on the conveying and metering of its powder, normally be stored in various powders in the material storage tube respectively, and utilize built-in agitating screw to continue to stir powder to avoid producing caking phenomenon, and with powder after the funnel-form discharging opening of below falls into the separate motors transmission feeder of system in addition, utilize the built-in screw feeding axle center of discharge nozzle of motor transmission feeder one side, make powder past gradually discharge end delivery with the rotation in screw feeding axle center, fall in the hopper at last and mix, via the discharge hole for discharge of hopper below, constitute the basic functional architecture of powder conveying metering according to this again.

But above-mentioned powder conveying measurement structure on reality is used, has following shortcoming:

One: because of its powder is measuring in the conveying, be to adopt motor transmission feeder to carry out, can't fit tightly between the screw feeding axle center of its motor transmission feeder and the tube wall of discharge nozzle, so necessarily have clearance space to keep the smooth and easy rotation in screw feeding axle center, thus, when its spiral delivery powder, be difficult to promptly guarantee that its powder can be by this gap space seepage, or G-card is between its screw feeding axle center, cause and get stuck or the situation of bleed, causing it to be difficult to obtain accurate control in the metering of discharging, for the powder conveying job requirements that needs delicate metering, is a serious and fatal shortcoming in fact.

Its two: because of the discharge nozzle inside of its motor transmission feeder has installed the screw feeding axle center, but add not tool perspectivity of its material, so when it gets stuck fault, can't know and learn its problem place, add the interference in its screw feeding axle center, the difficulty that causes its cleaning and fault to get rid of, even the screw feeding axle center must be taken out and just can carry out, reality is when trouble and inconvenience.

In other words, promptly the feed screw of this motor transmission feeder is real measures problem the very crux in the operation for powder conveying, adds the shortcoming that cleaning, maintenance difficult are arranged itself, remains to manage to solve improvement certainly.
