Full-automatic weighing and packaging system and control method thereof

Abstract

The invention relates to a full-automatic weighing and packaging system and a control method thereof. A first discharging valve, a second discharging valve and a third discharging valve are respectively arranged at the bottoms of a first charging bucket, a second charging bucket and a mixture stock bin of the full-automatic weighing and packaging system; blowers are mounted at the tops of the two charging buckets; the first discharging valve and the third discharging valve are respectively connected with the mixture stock bin through a first spiral powder metering scale and a second spiral powder metering scale; the third discharging valve is connected with a packaging mechanism; the two spiral powder metering scales, the three discharging valves, the mixture stock bin and the packaging mechanism are electrically connected with a control circuit respectively. The control method comprises the step as follows: the control circuit analyzes and processes measured parameters including weight, flow and the like in real time, and sends corresponding control signals to control flow, opening/closing of valves and starting/stopping of related equipment, so as to realize full-automatization control of weighing, mixing and packaging of two materials. According to the invention, the weighing is accurate, the raised dust is reduced, the pollution and labor force are reduced, and the working efficiency is improved.

Description

[0001] technical field [0002] The invention belongs to the field of packaging machinery, and in particular relates to a fully automatic weighing and packaging system which integrates weighing, stirring and packaging and has high precision, reduces pollution and improves efficiency, and its control method, which is suitable for the processing of tiny particles or powder materials Package. Background technique [0003] At present, although the packaging of tiny particles or powder materials in civil and chemical industries has achieved automatic weighing and packaging, there are still problems of low accuracy in weighing and packaging, especially for packaging powder materials. The dust problem affects the accuracy of weighing and packaging, pollutes the environment, and affects the health of the staff. And generally this kind of packaging is only for the packaging of a single material. If the two materials are to be mixed and stirred according to the set amount, and then p...

Problems solved by technology

[0004] The present invention mainly solves the problem that the original weighing and packaging equipment is only aimed at the packaging of one simple material, and cannot mix and stir the two materials according to the set amount before packaging, requiring staff to perform division of labor, which has the disadvantages of high labor intensity and low efficiency. Low technical problems; provide a fully automatic weighing and packaging system and its control method, which integrates weighing, stirring and packaging, and is completed by automatic control of the machine. The weighing and packaging are accur
