Synchronous control solution for paper machine
1. General overview
- Control solution for the system of high-speed paper machines with long-speed synchronization between batches (ice pressing, drying, optical press, roll…). Make the system stable and easy to operate. Produce quality products, increase machine efficiency, minimize waste and effectively save electricity.
- Papermaking is the process of forming a paper structure and turning the pulp solution into a finished paper. The paper machine is a combination of many transmission parts. It is divided into 2 parts: wet part and dry part.
- The wet part is composed of powder injection box, mesh unit, stone press unit. The powder sprayer is responsible for evenly spraying the pulp solution onto the mesh. The newly formed paper is then passed through the stone press to squeeze out the water and increase the bond between the fibers.
- The paper after passing through the wet part is still very moist (about 60%) will be dried to about 92% in the dry part, including pressing and drying rolls placed in series. To increase the quality and smoothness of the paper, at the end of the drying process there are also optical laminates. Finally, the finished paper will be rolled into large rolls by the roll collector.
2. Old-fashioned operating solution
- Machine parts are controlled separately from each batch.
- Easy to break paper, many waste products, uneven product quality.
- Low machine speed, low production efficiency.
- Almost no change in paper weight.
- Difficult to adjust, difficult to paper and troubleshooting.
- Regular maintenance of motors and mechanics affects the production schedule.
3. The solution for synchronous control of the optimal paper machine system
- Solution 1: Synchronous solution using inverter and PLC + HMI with machine speed up to 150m/min, open loop control using analog control, high frequency pulse or communication according to Modbus, Profibus standards… through PLC – HMI (To save costs, triviettech provides a synchronous control solution using only HMI and inverter to reduce the cost of control configuration).
- Solution 2: Synchronous solution using inverter and PLC + closed-loop control HMI to control and monitor with machine speed up to > 200m/min, using communication such as Modbus, network…, precise control with error 0.1%.
