The invention relates to the technical field of tobacco production, and provides a tobacco charging system and a control method of the tobacco charging system. The tobacco charging system comprises acharging machine and a belt weigher, wherein the belt weigher and the charging machine are arranged at an interval, the charging machine comprises a material storage tank, a charging valve, a spray nozzle and a charging pump, the material storage tank is connected with the spray nozzle through the charging pump, and the charging valve is arranged on a communicating pipeline between the charging pump and the spray nozzle. The system further comprises a control device in which a pre-filing set value is preset, the control device controls the rotation speed of the charging pump according to the pre-filing set value so that prefilling is carried out, the moment, collecting flow data, of the belt weigher is T0, after the moment T0, the control device controls the rotation speed of the chargingpump according to the flow data collected by the belt weigher and switches to the charging stage at the moment T0+T, wherein the duration T=T1-T2, T1 is the time used when tobacco shreds are conveyedbelow the spray nozzle from the belt weigher, and T2 is the time duration used when spice liquid is conveyed to the spray nozzle from the charging valve. For the tobacco charging system provided by the invention, the perfuming precision is improved through the control of the control device.
Description
technical field [0001] The invention relates to the technical field of tobacco production, in particular to a tobacco feeding system and a control method thereof. Background technique [0002] In the shredded tobacco processing technology, in order to improve the taste of cigarettes, the tobacco leaves / shredded tobacco must be processed by feeding (fragrance). Moreover, the precision control requirements for feeding (incense) are relatively high, and usually the error will be controlled within 1%. [0003] The current commonly used method is to install an electronic scale in front of the feeding system to detect the flow of tobacco material, and then multiply the flow rate of tobacco material according to the set feeding (incense) ratio to obtain the set feeding (incense) flow. The actual flow rate of the feed (incense) is detected by the flowmeter, and the motor speed of the feed pump is adjusted through PID control, so as to ensure that the actual feed (incense) flow is c...
