Powder packaging machine

Abstract

The invention discloses a powder packaging machine. The powder packaging machine comprises a packaging machine body and a vacuum pump, wherein the vacuum pump is used for enabling the interior of thepackaging machine body to be in a vacuum environment; the vacuum pump communicates with the packaging machine body through a guide pipe; a pressure gauge is arranged on the guide pipe and is used formonitoring the pressure intensity in the packaging machine body; a feeding device, a weighing device, a bag pulling forming device and a bag heat sealing device are arranged in the packaging machine body; the feeding device comprises a material cylinder, a feeding channel and an annular vibration disc, wherein the feeding channel enables the feeding device to communicate with the weighing device;the annular vibration disc is arranged on a first mounting plate fixedly connected to a main body frame of the packaging machine body; and the material cylinder is arranged on the annular vibration disc. According to the powder packaging machine, powder in the material cylinder is driven through the movement of the annular vibration disc to pass through through the feeding channel to enter a weighing hopper of the weighing device to be weighed; the vacuum pump is arranged, so that the powder packaging machine can be guaranteed to work in a vacuum environment, the flying dust phenomenon of lighter powder can be effectively inhibited by the vacuum environment, and a great effect on improving the weighing precision can be achieved; and by means of vibration feeding, the adhesion situation ofthe viscous powder can be avoided.

Description

technical field [0001] The invention belongs to the technical field of packaging machines, and in particular relates to a powder packaging machine. Background technique [0002] In the traditional powder packaging industry, there are screw method feeding, weighing method feeding and constant volume quantitative method feeding. However, the constant-volume quantitative method is suitable for low-accuracy requirements, and most of them can only be used for a single type of weighing packaging, such as the production packaging of large quantities of flour. Screw feeding is suitable for dry powder with moderate specific gravity. However, for the pigment field, such as heavy pigments with excessive specific gravity and powder with high viscosity, screw feeding is not only low precision but also easy to get stuck. Among them, the weighing method has a wide range of applications, and the feeding amount can be set according to the needs of the site, which is applicable to the packag...
