Basic steps and principles for setting the tension value of a flexographic printing machine
First, you need to understand the characteristics and requirements of the paper...
1. Understand the characteristics and requirements of the paper: The tension requirements of different types and thicknesses of paper may vary. Understanding the characteristics and requirements of the paper you use can help you set the tension value.
2. Check the tension sensor and control system: Ensure the normal operation of the paper tension sensor and control system. These devices can help you monitor and adjust the tension of the machine in real time.
3. Adjust the air pressure: Flexographic printing machines usually use air pressure to control the tension. Adjust the correct air pressure according to the type of paper and the requirements of the machine. Thicker paper usually requires higher air pressure, while thinner paper may require lower air pressure.
4. Set the tension control device: Flexographic printing machines are usually equipped with tension control devices such as tension sensors and tensioners. According to the paper type and requirements, adjust these devices to control and maintain the correct tension.
5. Test and adjust: Before formal printing, do some test printing and observe the results. According to the test results, gradually adjust the tension value until the printing effect and paper operation stability are obtained.
6. Pay attention to the running state of the paper: During the printing process, continuously observe the running state of the paper, including running speed, tension changes and the adaptability of the paper to the printing components. Adjust and optimize the tension value in a timely manner according to the actual situation.
