AI Technical Summary

Technical Problem

When conventional printing ink equipment malfunctions, the fixed and narrow gap between the printing rollers increases the time required for manual repairs, reduces repair efficiency, and easily leads to high waste smoke consumption.

Method used

By introducing an automatic control system into the ink printing unit of the roll-to-roll machine, and utilizing components such as cylinders, solenoid valves, relays, and control switches, the automatic adjustment and maintenance of the printing rollers can be achieved. This includes automatically adjusting the printing roller gap and adhesive application in the shutdown state, and timely detecting the uniformity of adhesive application.

Benefits of technology

It improved maintenance efficiency, reduced waste smoke consumption, ensured printing quality, and enhanced overall maintenance efficiency and the automation level of the printing equipment.

Abstract

The application belongs to the technical field of cigarette making machine, and discloses a printing roller automatic control method and system based on a cigarette making machine. After receiving a user's maintenance request instruction, the gear of the adjustment control knob can quickly turn on the electromagnetic valve and the circuit where the power supply is located, effectively improving the efficiency while making the electromagnetic valve in the on state and controlling the cylinder in the running state, so that the cylinder pushes the first printing roller to move towards the second printing roller under the on state of the electromagnetic valve until the first printing roller moves to a position convenient for manual maintenance observation, thereby ensuring the overall maintenance efficiency, and the method of controlling the movement of the printing roller can also effectively adjust the gap between the printing rollers, avoiding the defect of high waste smoke consumption caused by fixed and narrow gaps.
