A high-efficiency and high-precision filling powder packaging machine

Abstract

The invention provides a high-efficiency and high-precision packaging machine for powder filling. A stock bin is located at the top end of a machine frame. An air pre-pumping mechanism is installed on the machine frame and located below the stock bin. A feeding port of the air pre-pumping mechanism communicates with a discharging port of the stock bin. A spiral feeder is installed on the machine frame and located below the air pre-pumping mechanism. A feeding port of the spiral feeder communicates with a discharging port of the air pre-pumping mechanism. The feeding end of a variable-caliber discharging port communicates with the feeding port of the spiral feeder. The discharging end of the variable-caliber discharging port communicates with a vacuum chamber. The vacuum chamber is fixedly installed on the machine frame. A packaging bag pose control mechanism is located in the vacuum chamber and pulled through a packaging bag pulling and transferring sliding table. Air pre-pumping is achieved before powder enters a packaging bag, and the powder conveying efficiency is improved; accurate output of the powder is achieved through the variable-caliber discharging port, the situation that the powder falls in a caked mode is avoided, the powder filling accuracy is improved, and the effect that the working environment is clean is guaranteed; and by controlling the pose of the packaging bag during powder filling, the phenomenon that the powder is stacked into a pointed heap is avoided.

Description

technical field [0001] The invention belongs to the technical field of powder packaging machinery, in particular to a high-efficiency and high-precision filling powder packaging machine. Background technique [0002] At present, for the packaging stage of ultra-light and fine powder before leaving the factory, powder packaging machines are generally used to fill the powder into bags. Specifically, the powder is first sucked into the packaging bag by suction, and then the packaging The excess air in the bag is sucked away to realize the filling of powder. However, the powder filling method adopted by the existing powder packaging machine has low filling efficiency and low filling accuracy, long pumping time during the powder filling process, and easy filling of the packaging bag during filling. Powder pile peaks appear, resulting in uneven blanking. In addition, the diameters of the outlets of the existing powder packaging machines are all designed to be relatively large, a...

Problems solved by technology

However, the powder filling method adopted by the existing powder packaging machine has low filling efficiency and low filling accuracy, long pumping time during the powder filling process, and easy filling of the packaging bag during filling. Powder pile peaks appear, resulting in uneven falling

In addition, the diameters of the outlets of the existing powder packaging machines are all designed to be relatively large, and the diameters of the outlets are all fixed values. After the end of the discharge, some powders will always fall in groups, which not only affects the discharge Accuracy, but also pollute the working environment
