What are the characteristics of the slitter
Slitter is a kind of mechanical equipment which can cut wide paper or film into a variety of narrow materials. It is widely used in papermaking machinery, printing and packaging machinery. In the past, the speed of magnetic powder clutch of slicer can not be high, because it is easy to cause high-speed conflict of magnetic powder in the process of operation, resulting in high temperature, shortening the service life, and jamming in serious cases, which hinders the operation. The appearance of machines has brought serious results to production. Seriously affect the output power.
The traditional control scheme of slitter is to use large motor to drive rewinding and unwinding shafts. The magnetic powder clutch is added to the drum and the drum to control the resistance generated by the magnetic powder clutch to control the tension on the surface of the material. Magnetic powder clutch and brake are special active actuators, which transmit torque through magnetic powder filled in the working space.
Change the magnetic flux, change the magnetic condition of the magnetic powder, and adjust the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high speed subsection micro harmonic medium and small power speed regulation system. It is also used in unwinding or rewinding tension control system to adjust torque by adjusting current to ensure constant tension during winding.
The first winding roller and the second winding roller limit clamping, the core is punctured into the clamping, and the net is fed through the clamping; and at least one pair of electric joints is engaged to wind the end of the core, and at least one part of the winding cycle of the f package is completed.
In addition, a third winding roller is provided, which is a winding space limited by the first winding roller and the second winding roller, that is, movable to respond to the increase and completion of each packaged winding in the winding space.
The main machine is driven by variable frequency motor, and the winding is double bottom roller outer winding. The unwinding methods include: manual auxiliary feeding or shaftless hydraulic feeding, shaft barrel feeding, unwinding tension control, and advanced active control and active measurement. Loop number and emergency stop function.
The above is about cutting machine industry knowledge sharing, I hope we can love.
