Abstract

The invention relates to an operating method of a powder material packing scale, which is suitable to solve the problems that the packaging bag is unable to be vertically placed and the rated quantity of materials are difficultly put into the bag within a normal time when powder materials with high gas contents enter a packaging bag; and the dust is easy to fly everywhere, after the packaging equipment is used, a better effect is obtained, and the efficiency is improved. The packaging scale comprises a degassing blanking device which is arranged on an outlet at the bottom of a hopper, an air suction blowing combination valve group and a vacuum pump which are used for degassing, blowing and blockage removing and are connected with the degassing blanking device, and a pneumatic bag-clamping lifting mechanism which is arranged at the bottom of the degassing blanking device; and the degassing blanking device comprises a blanking barrel, integrated microporous filter elements are arranged at both the inner wall and the outer wall of the blanking barrel, and the pore diameters of the filter elements can be set according to the sizes of material particles, and can range between 50 mum and 1mum. Ports which are communicated with a clearance between the inner wall of the blanking barrel and the inner filter elements are arranged in the outer wall of the blanking barrel; and the ports are connected with air suction blowing combination valves.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 201110098349.X, the name: "Powder Material Packaging Scale", and the application date: April 20, 2011. technical field [0002] The invention relates to a packaging scale for packaging superfine powder materials with large gas content and a working method thereof. Background technique [0003] When the existing packaging scales pack ultra-fine powder materials with large air content, they cannot control the quantitative supply of powder materials, the packing density of materials is low, and the materials often have air bulges after entering the package, which makes it difficult to seal, Palletizing or bag standing problems, thus affecting the efficiency of packaging work. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a working method of a powder material packaging scale with reasonable structur...
