An online metering and monitoring system for cigarette machine stem label removal

Abstract

The invention provides an on-line metering and monitoring system for cigarette machine stem label removal. The system includes: load cell, high-precision amplifier, analog-to-digital conversion module, PLC operation controller, stepper driver, stepper motor, belt transmission mechanism, sound and light alarm, industrial network switch, touch screen, RJ45 connector. According to the setting parameters of the touch screen, the PTO drive pulse is generated, transmitted to the stepper driver for amplification and shaping, and the stepper motor is driven to rotate precisely; the weight of the loaded material is deducted from the tare weight to calculate the net weight of the material on the current belt; the PLC operation controller calculates for one second The material quality that passes through time is monitored and early-warned in combination with the set process parameter range. Compared with the traditional single-chip controller, inverter plus AC motor, and encoder, the reliability and stability are greatly improved, the volume and weight are greatly reduced, the control method is easier, and the accuracy is also higher. High, to achieve the needs of miniaturization applications.

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
