AI Technical Summary

Technical Problem

Existing feeding and metering devices cannot achieve accurate metering, resulting in an inability to precisely control the weight of each bag of product during packaging, and overall low efficiency.

Method used

The material feeding and metering device adopts a volumetric combination and compensation method. By using a combination of weighing hopper, feeding component and compensation component, it weighs in real time and stops feeding when the preset value is reached. It uses multiple micro-compensation hoppers of different sizes for precise compensation to ensure that the final material weight meets the standard.

Benefits of technology

It improves the accuracy and efficiency of feeding, ensures the weight accuracy of each bag of material, and speeds up the feeding process.

Abstract

The utility model discloses a kind of material feeding metering device based on volume combination adds compensation, including weighing bin, the top of weighing bin is fixed on frame by weighing assembly, the top of weighing bin is connected with feeding assembly and compensation assembly, and compensation assembly includes multiple different size trace supplementary hopper;Material can enter weighing bin by feeding assembly, weighing assembly continuously weighs weighing bin, when the weight of material in weighing bin reaches preset value, feeding assembly stops feeding, and weighing assembly feeds back the difference between current weight and standard value and opens corresponding trace supplementary hopper, so that the weight of material in weighing bin reaches standard value.The utility model directly feeds into weighing bin by feeding assembly and weighs in real time, when the weight of material in weighing bin reaches preset value, feeding assembly stops feeding and then opens corresponding trace supplementary hopper to feed, which guarantees feeding speed, and also guarantees the weight precision of final bagged material.
