Tobacco rod weight control method and device based on microwave source

Abstract

The invention discloses a tobacco rod weight control method and device based on a microwave source, which comprises: a cigarette machine simulation unit, a cigarette rod weight signal acquisition and control unit, a bottom board communication control unit and a host computer unit. The cigarette machine simulation unit imitates the microwave source probe to generate the analog signal of tobacco rod density, and automatically adjusts the mean value and phase of the tobacco rod density analog signal according to the chopper control signal; the tobacco rod weight signal acquisition and control unit samples the tobacco rod density analog signal, Automatically adjust the chopper control signal, and count the cigarette index; the bottom board communication control unit is used to connect the data communication between the upper computer unit and the cigarette rod weight signal acquisition and control unit; the upper computer unit is used to monitor the cigarette rod weight signal acquisition and Control unit health. The invention is applied to the tobacco rod production process of a high-speed cigarette machine, and can realize functions such as the control of shredded tobacco density and weight of cigarettes, detection and elimination of faulty cigarettes, statistics of cigarette indicators, and the like.

Description

1. Technical field [0001] The invention belongs to the field of industrial control and is mainly used for the control of cut tobacco density and weight of cigarettes, detection and elimination of faulty cigarettes, and statistical calculation of cigarette indicators in the production process of cigarette rods for cigarette machines. 2. Background technology [0002] Cigarette rolling machine is a machine that rolls shredded tobacco into cigarettes with cigarette paper. It is one of the important equipment in the production of cigarette industry enterprises and is a special equipment for producing filter cigarettes. The earliest cigarette rolling machine appeared in the 1860s, such as the machine invented by L. Susini, which was exhibited at the Paris Exposition in 1867. It first rolls the cigarette paper into an empty tube and then fills it with cut tobacco. The weight control of shredded tobacco in early cigarette making machines only relied on the shred feeding part—the s...

Problems solved by technology

The strontium 90 radioactive source is a radioactive substance. Regardless of whether the coiling unit is powered on or not, the radioactivity always exists and poses a long-term potential hazard to the surrounding personnel. The inspection and maintenance costs are expensive, which brings great inconvenience to the tobacco factory
