Self-circulating micro-addition device

Abstract

The invention relates to a self-circulating micro-addition device. The bracket is connected to the frame through the lifting adjustment mechanism; the feeding box is installed on the bracket, the vacuum storage bin is set above the feeding box, and the inlet of the feeding box is connected with the outlet of the vacuum storage bin; the vacuum storage bin An air pump is installed on the silo, and a filter element is installed inside the vacuum storage silo. The suction port of the air pump communicates with the inside of the vacuum storage silo through the filter element, and a live valve is installed at the outlet of the lower part of the vacuum storage silo; a feeding pipe is installed on the side of the feed box. , the feeding pipe and the feeding box are connected through a conveying pipe, and a conveying mechanism is installed in the conveying pipe; a cut-off cylinder is installed on the top of the feed pipe, and the piston rod end of the cut-off cylinder passes through the feed pipe downward and is connected to the cut-off valve; installed on the bracket The material retrieving cylinder and the material retrieving pipe that can slide up and down, the piston rod of the reclaiming cylinder is connected with the material retrieving pipe; the upper end of the material retrieving pipe is connected with the vacuum storage bin through a connecting hose. The invention has the functions of micro-feeding and micro-adding at the same time, and can solve the problem of measurement fluctuation of packaging quality.

Description

technical field [0001] The invention relates to a self-circulating micro-addition device, which belongs to the technical field of packaging metering equipment. Background technique [0002] With the continuous development of packaging measurement technology and automation technology, the degree of production automation is getting higher and higher. With the demand for mass production, quantitative packaging scales are more and more widely used in the packaging field. However, due to the inherent physical characteristics of the material itself, the material will always be more or less bonded to the inner wall of the discharge box of the packaging scale. When the amount of material accumulates to a certain extent, the accumulated material will fall off, causing the weight of the packaged material to fluctuate greatly within a certain period of time, causing certain economic losses to both the manufacturer and the consumer. , produce adverse effects, especially in the case of...
