Slitter is a large volume of paper, film, Non-woven, aluminum foil and other thin materials into different widths of the prepress, prepress 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, to produce serious consequences. Serious impact on productivity. Now for the use of dual-frequency inverter motor control, so that the diameter of the winding material in the case of variable-frequency motor control to make magnetic particle friction in a certain value. Without the heat.
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. 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 magnetic 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, 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.
Slitting machine continuously from single motor control to dual-motor, three-motor development, faster in the speed of the machine more stable and efficient.
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 disadvantage is that the speed is not high, high-speed operation is easy to cause magnetic powder high-speed friction, resulting in high temperature, magnetic powder clutch heat and shorten its life. Cutting a certain width of the coil with a tool to cut it lengthwise and into a number of devices with a narrower volume. It is installed in the calender or extrusion machine, glue machine and other unit devices, can complete continuous cutting, often with winding device. Cutting knife can be used flat blade and round mouth knife.
Paper processing Machinery slitting Machine Series products: disk paper slitter, small disk paper slitter, web slitter, high-speed slitting machine, etc.
Metal processing machinery slitter: Strip slitting machine, copper slitting machine, aluminum plate slitting machine, stainless steel slitting machine, tinplate slitting machine.
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. According to the working methods of slitting machine There are three kinds, divided into flat knife slitting, extrusion slitting and round cutter slitting. Flat knife slitting is like a razor, in the process of material operation to fall down, so as to achieve the purpose of slitting. This is two kinds of, the hanging cut is the material passes through two rollers, the razor drops the material lengthwise to cut, this kind of slitting way is convenient to the knife, the operation is convenient. Cutting groove Slitting is the material running in the knife groove roll, the cutter will fall in the groove of the Groove roll, cutting the material lengthwise. In the case of the Thin film of PP film or edge material, the cutting efficiency can be improved. But relative to the hanging cut, its disadvantage is that the knife is more inconvenient. Squeeze slitting is not common in the domestic slitting machine, it is mainly composed of a pneumatic knife which is synchronized with the material speed and has a certain angle bottom roll and convenient adjustment.
