Slitter With Dual Frequency Conversion Motor Control

- Jun 12, 2017 -

Slitting machine is a large volume of paper, film, non-woven fabrics, aluminum foil, mica tape and other thin materials divided into different width of the small volume of prepress, India equipment, commonly used in paper machinery and printing and packaging machinery.

Before the cutting machine magnetic powder clutch speed can not be high, because in the run-time easy to cause high-speed friction of the magnetic powder, Slitter resulting in high temperature, shorten its life, serious stuck, the machine running blocked, to the production of serious consequences.

Seriously affecting the production efficiency. Now the use of dual-frequency motor control, Slitter making the winding material diameter through the variable frequency motor control to make the magnetic powder friction in a certain value. Without high temperatures.

The traditional control scheme of the slitter is to use a large motor to drive the shaft of the rewinding roll. The magnetic clutch is added to the rewinding spool to control the resistance of the magnetic powder clutch to control the tension on the surface of the material. The Magnetic clutch and brake is a special automatic actuator, Slitter it is filled through the work gap in the magnetic powder transmission torque, change the magnetic current can change the magnetic state of the magnetic powder, and then adjust the transmission torque. Can be used from zero to synchronous speed stepless speed regulation, suitable for high-speed section of fine-tuning and low-power speed control system. Also used to adjust the torque by adjusting the current to ensure that the tension during the winding process to maintain a constant open or rewinding tension control system.

Slitter maintenance

(1) daily maintenance (daily routine hygiene)

A, keep the machine surface, Slitter guide roller and rubber roller clean.

B, with a gas gun by paragraph cleaning machine.

C, when cutting, to prevent the waste side and the blade scratch rubber roller.

D, in time to remove the crimping machine waste.

E, choose a good paper core, Slitter not brutal loading and unloading reel.

F, according to the mechanical lubrication diagram to refuel.

(2) month maintenance

A, clean air filter.

B, thoroughly clean the machine.

C, lubricate the parts by lubrication.

D, check the mechanical rotation of the situation, the loosening of the strong.

E, check the tension and life of the belt.

F, clean the dust on the cooling box.

G, cleaning the waste side of the fan filter.

(3) a maintenance

A, clean the whole machine, Slitter clean the guide roller and rubber roller.

B, check the tension and life of all belts, be adjusted or replaced.

C, the transmission part of the lubricating oil, grease.

D, clean the water filter, add oil to the oil mist.

(4) secondary maintenance

A, clean the whole machine, clean the guide roller and rubber roller.

B, check the mechanical transmission of the rugged situation, there are loose, to be strong.

C, check the tension and life of all belts, Slitter be adjusted and replaced.

D, EPC device refueling or oil change.

E, to the transmission part of the lubricating oil, grease.

F, clean up the water filter, oil mist, to the oil mist.

G, check the electrical system, clean the electrical box, motor.
