Novel cigarette quality detecting device used for putuo 70/90 cigarette making machine

Abstract

The invention relates to tobacco machinery and discloses a novel cigarette quality detecting device used for a putuo 70/90 cigarette making machine, which takes a gas leakage signal acquisition and a main controller as a core and also comprises a machine signal input unit, a removing control unit, a power supply processing unit, an analog output unit and a display unit, wherein the main controller receives gas leakage signals, machine sensor signals and touch screen setting signals, carries out computing and processing by a plurality of paths of high-speed analog-to-digital converters and a plurality of single chip microcomputers, controls the rejecting unit to reject cigarettes with quality defects and displays real-time data on a touch screen. In the cigarette quality detecting device, the states of air leakage, end loosing, appearance and no cigarette holders of the cigarettes can be detected in a more comprehensive manner, the cigarettes with quality defects in the production process of cigarettes are correctly rejected, the cigarettes with quality defects flowing into the market are greatly reduced, the product quality is comprehensively improved, simultaneously the working state of the cigarette making machine can be really reflected, and the maintenance working of the cigarette making machine is convenient.

Description

technical field [0001] The invention belongs to tobacco machinery, in particular to a cigarette quality detection device used in Pu Tuo 70 / 90 crimping unit. Background technique [0002] With the rapid development of the tobacco industry, the product competition among various cigarette manufacturing enterprises is intensifying day by day, and the focus of the competition is the quality of smoking flavor and cigarettes. Now, the entire cigarette market is oversupplied, and many cigarette factories have excess production capacity. They cannot take expanding production scale as the goal of development. Only improving the quality of their own products can be the fundamental way out for enterprise development. The production of high-quality cigarette products is inseparable from cigarette equipment with complete functions. How to improve the detection ability of cigarette machines is a project that every cigarette factory is very concerned about. [0003] Cigarette production is...

AI Technical Summary

Problems solved by technology

The positive pressure on the cigarette rolling machine needs to be used by many parts, and it cannot be guaranteed to be stable. In particular, there will be vibrations in the air pressure, which cannot be completely eliminated through the pressure regulating valve, but this vibration is very important for the simple detection of the original machine. As far as the method is concerned, it has a very large impact, which will cause the instability of the detection value

The detection air path of the original machine is connected to the sensor through the rubber hose, but the rubber hose has hysteresis and attenuation to the air pressure change, which will cause the air pressure change at the sensor end to become smaller, and the response time will be delayed. In addition, the rubber hose is exposed to the outside, and mechanical vibration is inevitable. , these factors will cause the detection sensitivity to decrease and the anti-interference ability to decrease

In the end, the sensitivity of the system is not high, and the actual use effect is not ideal

[0006] Problems with the quality inspection and control system: the quality inspection system of the original machine is composed of multiple circuit boards, the functions of each circuit board are interrelated, the connection is complicated, and there is no human-machine interface, many important parameters cannot be observed, and it is difficult to check the system parameters. Make detailed adjustments, resulting in unsatisfactory actual use results

If there is a problem with the system, it is necessary for the on-site maintenance personnel to have relatively high circuit analysis ability to solve the problem, which makes the on-site maintenance very inconvenient

And the number of circuit boards is large, the failure rate is high, and the cost of use and maintenance is high
