Elevating belt control method for cut tobacco transportation device

Abstract

The invention belongs to the field of tobacco production equipment, and particularly relates to an elevating belt control method for a cut tobacco transportation device. The elevating belt control method for the cut tobacco transportation device is provided and comprises the steps that a feeding machine conveys cut tobaccos to an elevating belt, the cut tobaccos are elevated through the elevatingbelt and then pass through a belt weigher, and cut tobacco weight x of the feeding machine within unit time and the cut tobacco weight m of the balance weigher within unit time are measured, the output power of the elevating belt is m / y, and y=0.2879x+152.73. Through study on the elevating belt running rule, induction calculation is conducted according to the cut tobacco weight of the feeding machine and the cut tobacco weight of the belt weigher, and the running rule of the elevating belt is obtained. It can be obtained through the experiment measurement that due to the provided technical scheme, frequent elevating belt starting and stopping can be effectively avoided, the elevating belt speed (namely the output power) is kept within a smooth and stable range, and the function of elevating belt protection is better achieved; and the technical defects that in the prior art, an elevating belt of cut tobacco transportation equipment is frequently started and stopped and is prone to damage are overcome.

Description

technical field [0001] The invention belongs to the field of tobacco production equipment, and in particular relates to a lifting belt control method of a shredded tobacco transport device. Background technique [0002] In the shredded tobacco production line, the feeder is used as a material buffer device, and the material is output to the electronic belt scale through the lifting belt to ensure sufficient material supply for the electronic belt scale and achieve the purpose of constant output material flow. [0003] In the process of practical application, due to the many grades of shredded tobacco produced, the rated flow rate of the same belt scale is also different when the grades are different. In the prior art, the speed of the lifting belt is switched according to the height of the material level detected by the high and low photocells of the metering tube, but the same setting value cannot meet the needs of various flow rates. [0004] However, in the shredded toba...

Problems solved by technology

In the existing technology, the speed of the lifting belt is switched according to the height of the material level detected by the photoelectric tube at the high and low positions of the metering tube, but the same setting value cannot meet the needs of various flow rates

[0004] However, in the shredded tobacco transportation equipment in the prior art, the operating speed of the lifting belt is based on the frequency of the frequency converter that has been set. During use, it is easy to cause frequent start and stop of the lifting belt, resulting in damage to the lifting belt and shortening the service life of the lifting belt.

[0005] Therefore, developing a lifting belt control method of shredded tobacco transportation device, which is used to solve the technical defects of frequent start-stop and easy damage of the lifting belt of shredded tobacco transportation equipment in the prior art, has become a problem to be solved urgently by those skilled in the art
