Double-stations reweighing metering method for fine powder materials packaging

Abstract

The invention provides a double-stations reweighing metering method for the fine powder materials packaging. The method is characterized in that the fine powder material is subjected to material filling to the packaging bags in the first station, and rough metering is completed; a station converting device is used for transferring the materials of the first station to the second station together with the packaging bags, the second station is used for carrying out weight rechecking and calculating a materials supplementing amount on the packaging bags, and materials filling is carried out againaccording to the material supplementing amount; the packaging bags are sealed and conveyed out of the equipment at the third station. According to the method, the weight rechecking and material supplementing amount calculating are carried out at the second station, and the materials filling is carried out again according to the material supplementing amount, and the problem of material loss caused by long air pumping time of materials on a first station is solved.

Description

technical field [0001] The invention relates to the technical field of material packaging, in particular to a double-station reweighing measurement method for fine powder material packaging. Background technique [0002] In the existing packaging equipment, when packaging ultra-fine powder materials, there will be floating dust in the packaging environment. If it is not handled in time, it will cause great difficulties to the environment and maintenance of the packaging site and equipment. , and some mechanisms of the equipment cannot be completely dust-removed and sealed. In the existing micro-powder packaging, although double stations are also used, the weight measurement mechanism is only set on the first station, and there is no subsequent weight re-inspection, and the fine powder is in the packaging process, especially when feeding at the first station. The dust is large, the pumping time is long, and the powder is lost in the process. Therefore, if only one weight mea...

Problems solved by technology

[0002] In the existing packaging equipment, when packaging ultra-fine powder materials, there will be floating dust in the packaging environment. If it is not handled in time, it will cause great difficulties to the environment and maintenance of the packaging site and equipment. , and some parts of the equipment cannot be completely dust-removed and sealed

In the existing micro-powder packaging, although double stations are also used, the weight measurement mechanism is only set on the first station, and there is no subsequent weight re-inspection, and the fine powder is in the packaging process, especially when feeding at the first station. The dust is relatively large, the pumping time is long, and the powder is lost in the process. Therefore, if only one weight measurement is performed, there will be errors in the final feeding, which cannot meet customer requirements.

[0003] Existing metering devices usually only have one station for metering and packaging, especially for relatively light materials with general fluidity, it is inevitable that there will be certain weight fluctuations when feeding materials at one station, which cannot meet the accuracy requirements. value, or the speed is slow, or the measurement is inaccurate, it is difficult to achieve a balance
