Online measurement monitoring system for sliver rejection of cigarette making machine

Abstract

The invention provides an online measurement monitoring system for sliver rejection of a cigarette making machine. The system comprises a force measuring sensor, a high-precision amplifier, an analog-to-digital conversion module, a PLC operation controller, a stepping driver, a stepping motor, a belt transmission mechanism, an audible and visual alarm, an industrial network switch, a touch screenand an RJ45 connector. PTO driving pulses are generated according to set parameters of the touch screen and transmitted to the stepping driver to be amplified and shaped, and the stepping motor is driven to accurately rotate; the material weight is loaded and the tare weight is deducted to calculate the net weight of the material on a current belt; and the PLC operation controller calculates the mass of the material flowing through within one second, and performs monitoring and early warning in combination with a set process parameter range. Compared with a traditional mode that a single-chipmicrocomputer controller, a frequency converter, an alternating current motor and an encoder are adopted, the mode of the invention has the advantages that the reliability and the stability are greatly improved, the size and the weight are greatly reduced, the control method is easier, the precision is higher, and the requirement for miniaturized application is met.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to an on-line metering and monitoring system for removing cigarette machine stems. Background technique [0002] When the stem sticks enter the cigarette, it is easy to pierce the cigarette paper, which is not good for the smoking state and quality improvement of the cigarette. For this reason, the cigarette machine is designed with a stem stick removal device. In order to improve product quality, cigarette companies require that during the rolling process of cigarettes, there are strict requirements on the proportion of shredded tobacco stems in cigarettes. The culling ratio. However, the current equipment lacks a real-time metering and monitoring device to monitor and measure the ratio or flow rate of stemming removal. The current supervision method is quality inspectors touring spot checks and manual measurement. First, the workload is heavy; second, spot checks onl...

Problems solved by technology

There are also electronic scales for high-precision static measurement on the market. The accuracy is also very high, up to 0.1 grams, but it can only perform static measurement. On-line real-time display and warning are far from meeting the needs of tobacco factories for on-line monitoring and measurement of stem labels
