Feeding control method and system for thin-plate cut-tobacco drier

Abstract

The invention provides a feeding control method and system for a thin-plate cut tobacco dryer. The method comprises the steps that an outlet vibration groove is formed in an outlet of a storage cabinet type temporary storage cabinet, a material stirring roller is arranged in the outlet vibration groove to loosen cut tobacco, and the outlet vibration groove pushes the cut tobacco into a lifting belt through vibration. A hopper is arranged at an inlet of the quantity limiting pipe, the quantity limiting pipe is vertically arranged below the hopper, the lifting belt conveys tobacco shreds into the hopper, and then the tobacco shreds are conveyed into the quantity limiting pipe through the hopper. The limiting tube is partitioned from top to bottom, and a correlation photoelectric tube is arranged in each partition of the limiting tube so as to detect the tobacco shred stacking height in the corresponding partition. And the tobacco shred stacking position in the limiting pipe is obtained according to the tobacco shred stacking height in each partition, and the feeding speed of the lifting belt is subjected to speed regulation control according to the tobacco shred stacking position, so that the tobacco shred stacking position in the limiting pipe is located in a set interval. The service life of equipment can be prolonged, and the working efficiency of the equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of cut tobacco production, in particular to a feed control method and system for a thin-plate shredding machine. Background technique [0002] At present, the technological process of the silk-making line in the field of cigarettes is that the flaked tobacco leaves are processed by the shredder, and the physical form is converted from the flaked tobacco leaves to the shredded tobacco, which is then processed by thin-plate shredding before entering the next process. The thin-plate drying process, as the last process of tobacco moisture control, plays a key role in the quality of tobacco. The principle of moisture control of the thin-plate wire drying machine: The PLC system collects the flow rate of the front electronic scale and the moisture content of the incoming cut tobacco. The theoretical dehydration value can be achieved by adjusting the wall temperature, hot air temperature and the opening of the moi...
