Powder packing and measuring device and method

Abstract

The invention discloses a powder packing and measuring device and method; the powder packing and measuring device is adopted to measure and pack powder with non-constant stacking density and comprises a vertical tubular measuring container; the upper opening of the measuring container is connected with an ash hopper connected with a feeding device, and the lower end is a discharging opening connected with a packing bag; a powder feeding valve and a powder discharging valve are arranged in the measuring container from top to bottom; the volume of the measuring container between the powder feeding valve and the powder discharging valve matches with that of the packing bag; and a level gauge is arranged above the powder feeding valve. The measuring and packing manner for a constant volume is realized; the device is compact in structure, smooth in discharging, low in fault rate, stable in running and accurate in measuring; the high fill rate of the packing bag and the clean environment during packing are ensured; in combination of the disclosed and matched powder packing and measuring method, the fill rate of the packing bag is improved effectively and the overflow rate of the packing bag is reduced.

Description

technical field

[0001] The invention relates to a powder packaging and metering device and method, in particular to a powder packaging and metering device and method with uneven bulk density. Background technique

[0002] The existing powder measurement and packaging methods all adopt the weighing measurement packaging method, and the electronic scale calculates the cumulative calculation of the powder materials weighed within a certain period of time. After reaching the preset measurement value, the weighing procedure is completed, and the guidance The follow-up packaging mechanism carries out the bag clamping and filling process. This metering and packaging method can achieve constant weight packaging, which is suitable for the packaging of most powder materials with constant density. For example, the authorized announcement number is "CN203005773U", and the patent number is a utility model patent of ZL201220734756.5, which discloses "a packaging scale with dust removal fu...
