Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metering devices, in particular to a material consumption on-line metering device for a cigarette factory silk making workshop. BACKGROUND

[0002] In the production process of the silk making workshop of the cigarette factory, there are multiple point screening mechanisms for dust, smoke, stems and other materials. The screened materials are directly recycled by the negative pressure pipeline system without a metering system. At present, intelligent manufacturing is advocated, and there is no basic data for analyzing production consumption, production efficiency and production management data. Therefore, in order to adapt to the needs of modern intelligent production management, the screened materials need to be metered. The material consumption on-line metering device is mainly used for real-time monitoring and accurate accounting of material consumption in industrial production process, improving resource utilization efficiency and optimizing production management. The core value lies in real-time monitoring of material consumption in the production process, real-time statistics and real-time analysis of the recycling amount of screened materials, real-time communication with the production management center.

[0003] In the silk making workshop, part of the existing technology is to set a recycling device at the end of the screening system. The recycling device directly falls into the recycling hopper through the synchronous rotation of the screw conveyor and the impeller, and is sucked away by the negative pressure pipeline. The structure is simple and can meet the basic recycling needs, but there is no metering equipment, so the recycling amount cannot be counted, data analysis based on statistical data cannot be carried out, and communication with the production management center cannot be carried out, which cannot meet the basic needs of digitalization and intelligentization of modern cigarette factories. Without effective data, production efficiency, equipment or material abnormalities cannot be analyzed and counted; when manufacturing tobacco, tobacco leaves are cut into tobacco, and then dried, cooled and screened to separate out broken ends and too long tobacco, to ensure uniform particles. However, the high-frequency friction between the material and the screen in the dry environment will generate static electricity, causing the light materials such as tobacco and stems to be charged. When the screened materials fall, the static electricity causes the particles to be attracted together, or to be attracted to the inner wall of the metering device feeding port made of metal material. Therefore, part of the material in the actual material flow fed into the material consumption metering device will not be counted due to the adsorption of the inner wall of the feeding port, resulting in metering deviation and directly affecting the accuracy of data analysis.

[0004] Therefore, the present application provides a material consumption on-line metering device for a cigarette factory silk making workshop, which solves the problem of material electrostatic adsorption before dynamic weighing and ensures data accuracy. SUMMARY
