Straight-through feeding mechanism with airflow assistance for packaging machine

Abstract

The invention relates to a straight-through feeding mechanism with airflow assistance for a packaging machine, comprising a packaging frame fixedly installed on a packaging machine body, wherein an impeller box and a feeding motor are fixedly installed on the packaging machine body, an impeller is disposed in the impeller box, a three-position cylinder is installed on the packaging frame, an installation plate is fixed on the packaging frame, a feeding nozzle is fixed on the installation plate, a connection hose is disposed between the discharge hole of the impeller box and a charge port of the feeding nozzle, a first check valve is fixed on the impeller box, a first gas inlet hole is disposed on the impeller box, and the outlet of the first check valve is disposed by deviating from the axis of the impeller box; a second check valve is fixed on the installation plate, and a second gas inlet hole is disposed on the feeding nozzle; and a valve is disposed on the packaging frame, and thevalve is controlled by the three-position cylinder. The straight-through feeding mechanism with airflow assistance for a packaging machine disclosed by the invention has the following advantages thatthe phenomenon of single packaged product of a packaging machine is avoided, thereby improving the universality of packaging machine; and the occurrences of blocking phenomenon is reduced, thereby increasing the production efficiency.

Description

technical field [0001] The invention relates to a device for packaging various powdery and granular materials, in particular to a straight-through airflow auxiliary feeding mechanism of a packaging machine. Background technique [0002] Packaging machine is an important equipment for packaging various powder materials. Before the present invention was made, in the domestic existing product technology, the feeding mechanism had no airflow to assist filling, and the feeding nozzles were mostly arc-shaped. When filling the material, it is easy to cause the material to block the feeding nozzle, resulting in too slow filling speed and low production efficiency; the particles with low density (such as medicine powder, aluminum powder, silicon powder, etc.) cannot be filled. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a kind of machine that can avoid the clogging of the feeding mechanism, in...
