Tobacco online weighing device

Abstract

The invention provides a tobacco online weighing device which comprises a belt conveying device I, a belt conveying device II, a transport weighing device, a PLC control system and a computer. The belt conveying device I is provided with a photoelectric sensor and a travel switch. The PLC control system controls the working of a servo motor. When the photoelectric sensor detects an electric signal, the photoelectric sensor sends a command to the servo motor to control the servo motor to start working to drive the transport weighing device to move to the direction of the belt conveying device II, when the transport weighing device returns and touches the travel switch, the servo motor stop working, and a strain type weighing sensor transmits detected data to the computer at the same time. According to the device, through using a crank slider mechanism, the tobacco on the belt conveying device I is transported to the belt conveying device II in the process of weighing, the weighing is completed in the conveying process, the online real-time weighing of the tobacco is realized, the efficiency is improved, and the extraction of the subsequent characteristic parameters in the belt conveying device II is not affected.

Description

technical field [0001] The invention relates to a weighing device, in particular to an online weighing device for tobacco leaves. Background technique [0002] Tobacco leaf is one of the main raw materials in the production of flue-cured tobacco products in my country.
