In the fast-growing paper consumption, the traditional slitting process has not been able to meet the production requirements and quality requirements of the products. The traditional slitting machine uses the magnetic powder clutch to work. This is the most primitive cutting mode. It has experienced semi-automatic control, digital control, digital control and so on. The cutting machine industry has developed into servo. Development of transmission control, cursor tracking control, PLC control, and variable frequency control.

         Although there are still some semi-automatic slitting processes on the market, these are used in small paper, printing and packaging manufacturers. In the domestic large-scale paper processing, printing, packaging and other intermediate cutting processes have gradually applied the latest servo drive, cursor tracking system and other new cutting methods. With the rapid development of the paper processing industry, it is believed that in the next few years, the automatic slitting machine will occupy a place in the process of cutting paper products and gradually occupy the market.
         Hydraulic paper holder: The modern paper holder adopts the method of hydraulic paper clamping. Through the hydraulic transmission to the electric, the signal in the electrical is transmitted to the computer servo control system, and the servo control system will be electrically transmitted. Information, feedback control of the operation of the platen by a series of ways in which the analog signal is converted into a pulse signal. When the paper is uneven in the platen, or the roll core becomes small, and the paper exit speed is slow, the servo control system starts from The key role is to make the cut paper more accurate and of better quality. The new hydraulic pressure is also divided into two types: one is horizontal and the other is vertical.
         Innovations in recurve: The recurve frame also plays a key role in the accuracy and quality of paper cutting. When the paper is not flat and the conveying speed is too slow or too fast, the angle of the paper is inconsistent with the ideal angle. The control system in the rack transmits information through the recurve frame, and the system automatically feeds back the angle of the paper. The recurve frame can make the paper in a tight state, so that in the later cutting work, the phenomenon of stacking paper and paper error are not easy to occur. The recurve also has an important role. When a brake alarm occurs, the recurve can stop the quick work and reduce paper waste. The recurve frame is also divided into automatic and manual forms, which can be designed by the manufacturer according to their own needs. The recurve also has an important function that corrects the paper to automatically level when the paper is rolled.
         With the rapid development of market demand and the rapid development of technology, the upgrading of science and technology is an inevitable trend of the development of the times.
