Problems solved by technology

This process has the following disadvantages: 1. The powder distribution is uneven during the cloth process, and it is difficult to ensure the uniformity of the powder density after the cloth even after scraping, which directly affects the density of the air electrode pole piece
2. The "constant volume-straight tilting-scraping" of this cloth method are independent processes, which cannot be continuously produced, and the production efficiency is low

Abstract

The invention relates to a material distributing machine used for dry-embedded molding manufacture technology of an air electrode for a zinc-air battery. The material distributing machine comprises four parts of a quantitative feeding mechanism installed on a rack, a casting mechanism, a nickel screen delivery mechanism and a material recycling bin; and the material distributing machine is characterized in that the quantitative feeding mechanism comprises a hopper, a screw feeding main shaft and a shell thereof, a feeding servo motor and the like; the casting mechanism comprises a material beating bar, a material beating roll, a material beating roll shaft, a material-sprinkling motor and the like; the nickel screen delivery mechanism comprises a nickel screen, a feeding roll, a feeding roll main shaft, a bearing cover, a nickel screen shaft coupler, a servo motor bracket, a servo motor and the like; and the material recycling bin is installed below a material distributing bin supporting plate. The material distributing machine can automatically complete material evenly-distributing work in the dry-embedded molding manufacture technology of the air electrode for the zinc-air battery.

Description

technical field [0001] The invention relates to the manufacturing technology of battery pole pieces, in particular to a distributing machine used in the dry insert forming manufacturing process of the air electrode of the zinc-air battery. Background technique [0002] At present, the air electrode pole piece of zinc-air battery generally adopts the "constant volume-straight tilt-scraping" cloth process. The method of producing air electrode pole pieces of zinc-air batteries by this mold method is to spread the electrode material directly in a fixed mold, cover the middle with a nickel mesh as a current collector, and then scrape the powder flat. This process has the following disadvantages: 1. The powder distribution is not uniform during the cloth process, and it is difficult to ensure the uniformity of the powder density after the cloth even after being scraped, which directly affects the density of the air electrode pole piece. 2. The "constant volume-straight tilting-s...
