Slitter is a broad paper or thin film into a wide range of narrow materials of mechanical equipment, often used in paper machinery and printing and packaging machinery.
The former slitter magnetic powder clutch speed can not be high, because in the operation of the high speed friction caused by magnetic powder, resulting in high temperature, shorten its life, serious will be stuck to die, so that the machine operation is blocked, Slitter to produce serious consequences. Serious impact on productivity.
The traditional control scheme of the slitter is to use a large motor to drive the shaft of the retractable roll, and the magnetic powder clutch is added on the reel to control the resistance produced by adjusting the current of the magnetic particle clutch to control the tension of the material surface. Slitter Magnetic powder clutch and brake is a special automatic actuator, it is through the filling in the work gap of the magnetic powder transfer torque, change the excitation current can change the magnetic state, and then adjust the transmission torque. It can be used for stepless speed regulation from zero start to synchronous speed, Slitter and it is suitable for speed adjustment system with high section and small power. It is also used to adjust the torque by adjusting the current to ensure a constant unwinding or rewinding tension control system during winding.
The main feature of the slitter is the magnetic powder clutch as a resistance device, through the system control, to output a DC voltage, control the magnetic particle clutch generated resistance. The main advantage is that it is passive device, which can control the small tension.
The type of slitting machine is increasing and the classification method is different. According to the requirements of the size of the paper can be divided into paper slitting machine and small plate slitter.
Maintenance of slitting Machine
The main parts of automatic slitting machine should be inspected before use, add lubricating oil; in the inspection and disassembly automatic slitting machine, strictly prohibit the use of improper tools, Slitter the use of unscientific operation methods, every two weeks to the machine to do a comprehensive clean-up and inspection; automatic slitter if not longer than a long time to stop, you must wipe all the bright surface, Apply Antirust oil, cover the whole machine with plastic sleeve. such as automatic slitting machine to stop up to March above, Slitter should be on the anti-rust oil on the moistureproof paper; After the work is finished, carefully clean the equipment, and wipe out the exposed grinding surface clean, add lubricants.
To do a good job in the daily maintenance and maintenance of cutting machine to do the following five points.
First, the electrical parts should be regularly cleaned and inspected, in time to remove hidden dangers.
Second, the use of slitting machine is a longitudinal cutting machine to complete, so, to use high-quality slitting knife and cross-cutting knife.
Third, the daily maintenance of slitting machine to be in place, its criterion is, smooth, clean, liquidation (no dust, no debris) in place, to ensure that the equipment sliding parts in good condition.
Four, it is maintenance work, the rotation of the parts to stop regular and irregular inspection (especially for vulnerable parts to stop real-time monitoring). The implementation of regular adjustment, regular change, Slitter commutator and do a careful record, to reach the purpose of prolonging the service life of equipment.
Five, improve the operation of cutting machine technical quality and degree of the control of local operations to do, Slitter without the consent of anyone not to operate。
