Volumetric type automatic quantitative packing machine and capacity regulating device thereof

Abstract

The invention discloses a capacity regulating device for a packing machine. The capacity regulating device comprises an upper capacity body and a lower capacity body which sleeve with each other, wherein a charge hole is formed in the upper part of the upper capacity body; a discharge nozzle is arranged on the lower part of the lower capacity body; an upper flange is fixedly arranged outside the upper capacity body; a plurality of nuts are fixedly arranged on the upper flange; a vertical lead screw is screwed into each nut; a chain wheel is fixedly arranged at the upper end of each lead screw;chain wheels of each lead screw are synchronously connected through a chain, and a regulating device is arranged at the upper end of one lead screw; a lower flange is fixedly arranged outside the lower capacity body, the lower end of the lead screw is inserted into each light hole of the lower flange, and the lower end of the lead screw is equipped with an anti-dropping choke plug. The capacity regulating device realizes quantitative packing on solid materials according to the volume, and overcomes a phenomenon that packing capacity is affected by moisture changes of the material. Especiallyfor quantitative packing for a nursery substrate fertilizer plant, quantifying uniformity is high, filling speed is high and production efficiency is high, so that online loading of fertilizer enterprises is facilitated, and the handing cost and reservoir capacity occupation are reduced.

Description

technical field [0001] The invention belongs to the field of packaging machines, and relates to a volumetric automatic quantitative packaging machine and a capacity adjustment device used therein. Background technique [0002] At present, the quantitative packaging of light materials such as special fertilizers for seedling raising substrates, grass carbon, perlite, vermiculite, etc., especially solid materials with large weight changes per unit volume due to the influence of moisture, is manually packaged with shovels. Some advanced ones use weighing packaging equipment for bagging. Not only the speed is slow, the measurement is inaccurate, the labor intensity of the employees is high, but also the working environment is very poor, which affects the health of the staff. What's more, it is measured by weighing principle. When the water content of the material is large, the tolerance is too large but the weight is sufficient. When it is used by the user, the quantity is obvi...

Not only the speed is slow, the measurement is inaccurate, the labor intensity of the employees is high, but also the working environment is very poor, which affects the health of the staff

What's more, it is measured by weighing principle. When the water content of the material is large, the tolerance is too large but the weight is sufficient. When it is used by the user, the quantity is obviously insufficient, which will affect the effect and benefit of greenhouse fruit and vegetable seedlings, resulting in an increase in seedling costs. Farmers’ confidence in substrate fertilizer manufacturers has decreased, which has affected the production and development of substrate fertilizer factories, and in turn affected the production and sales of oxalic acid, vermiculite and other substances. troubled
