Problems solved by technology

[0004] However, in the control process of this belt quantitative delivery, since the inclined feeding belt 3' runs forward at a certain speed ("front" refers to "the direction towards the dipping tank 4'"), the initial drop to the inclined feeding The shredded tobacco on the belt 3' has not reached the set value of the distance measuring photocell 2', so when the subsequent shredded tobacco falls on the inclined feeding belt 3', the initial shredded tobacco will run forward along with the inclined feeding belt 3' for a period of time.

Abstract

The invention relates to a control method and device for belt quantitative conveying. The method comprises the steps of measuring the instant flow of tobacco shreds falling from a discharging vibration groove to an inclined feeding belt, and controlling the running frequency of the inclined feeding belt according to the measured instant flow of the tobacco shreds. According to the control method and device for belt quantitative conveying, the heights of the stacked tobacco shreds on the inclined feeding belt can be kept uniform, and the stability of the weight of every batch of tobacco shreds entering a dipping tank is ensured.

Description

technical field [0001] The invention relates to the field of tobacco automatic control, in particular to a control method and device for belt quantitative delivery. Background technique [0002] CO 2 Shredded tobacco expansion technology is one of the most important technologies for producing expanded shredded tobacco in cigarette production. Shredded tobacco enters a large CO 2 Dip tank, using CO 2 The physical properties of the tobacco can change the physical structure of the cut tobacco to achieve the expansion effect on the cut tobacco, so as to achieve the purpose of reducing the tar content of the cut tobacco and increasing the filling value. Tobacco enters CO 2 Before the impregnation tank, there is a long oblique feeding belt. Due to technological requirements, the shredded tobacco must be pre-distributed on the oblique feeding belt before entering the impregnation tank. By controlling the oblique feeding belt, each batch enters the impregnation process. The amou...
