1, understand the paper characteristics and requirements: different types and thickness of paper tension requirements may be different. 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 your machine in real time.
3, adjust the air pressure: Flexo printing machine usually uses air pressure to control tension. Adjust the correct air pressure according to the paper type and machine requirements. Thicker paper usually requires higher air pressure, while thinner paper may require lower air pressure.
4, set tension control device: Flexo printing machine is usually equipped with tension control device, such as tension sensor and tensioner. Depending on the paper type and requirements, these devices are adjusted to control and maintain the correct tension.
5, test and adjust: before the official printing, some test printing and observe the results. According to the test results, the tension value is gradually adjusted until the printing effect and the running stability of the paper are obtained.
6, pay attention to the running state of the paper: continue to observe the running state of the paper during the printing process, including the running speed, tension changes and the adaptability of the paper to the printing parts. Adjust and optimize the tension value according to the actual situation.
