Embodiment Construction

[0028] Embodiment Using the automatic speed regulation control method of the shredding machine based on the accumulation algorithm of material bulk density of the present invention, in May 2015, the shredding process of Baisha fine second-generation tobacco leaves was carried out automatic speed regulation control on the YS213A type shredding machine. The steps are as follows:

[0029] (a) Calculate the initial material bulk density ρ of tobacco leaves 0

[0030] (a-1) Put Baisha fine second-generation tobacco leaves into the shredding machine, and record the test shredded output G per unit time under the normal operation of the shredding machine s , according to the formula (1) to calculate the design shred output G of the shredding machine for Baisha fine second-generation tobacco leaves.

[0031]

[0032] In the formula (1), G is the designed shredded output per unit time under the normal operation of the shredder, unit kg / h; G s It is the test shred output per unit ti...

Abstract

The present invention relates to the tobacco production technology field, in particular relates to and provides a material volume-weight accumulation algorithm-based tobacco cutter automatic speed regulation control method and device which aims at the insufficiencies that a tobacco material volume-weight reasonable calculation method does not exist in the prior art and the automatic speed regulation control of a tobacco cutter is difficult to realize. According to the present invention, a knife roll adjustment rotating speed nt is obtained by calculating an initial material volume-weight rho0, the initial knife roll rotating speed n0 of the tobacco cutter and a material volume-weight average value of the tobacco, and the current knife roll rotating speed n of the tobacco cutter is adjusted according to the knife roll adjustment rotating speed nt. The method and the device of the present invention are both simpler in algorithm design and equipment structure, lower in implementation cost, excellent in control effect and wide in application prospect, and both have the good suitability with the current various cigarette primary processing lines of the tobacco production industry.

Description

technical field [0001] The invention relates to the technical field of tobacco production, in particular to an automatic speed regulation control method and equipment for a shredding machine based on a material bulk density accumulation algorithm. Background technique [0002] The cutting machine is one of the important equipments in the tobacco shred production line, it is widely used, and it is also one of the mature equipment with better performance in the shred line. However, the prior art cannot realize the automatic speed regulation of the shredding machine, which causes the shredding machine to be unable to realize automatic control in a real sense in practical applications, let alone remote control. The material bulk density (also known as the material coefficient) of tobacco will vary depending on the origin of the tobacco. The prior art lacks a standard statistical method for the bulk density of tobacco materials, which is also the difficulty in realizing the auto...
