1. Introduction to the machine:
This machine is a kind of high precision, high sensitivity, reliable production performance of the slabbing equipment, the use of slip shaft for receiving materials, the use of air expansion shaft for discharging materials, tension controlled by magnetic powder clutch. Unwinding deviation adopts automatic photoelectric deviation control, can realize automatic detection, automatic meter count. Equipped with raw edge cutting, waste edge automatic processing device. Accurate stripe, fast stripe, easy operation and easy maintenance. This product is suitable for the whole drum of lithium battery isolation film cutting into the required width, by the isolation ring to do the width setting, the disc knife for longitudinal motion to achieve the purpose of cutting, drive with servo motor, smooth operation, low noise, can ensure high precision cutting rewinding.

3、Product advantage:
It can cut ultra-thin and ultra-thick power battery electrode very well.
After the strip is not easy to appear fold, depowder, high precision of the size of the strip, small edge burr.
l Wavy edge: Drop off and wavy edge defect in pole cutting, wavy edge. When the wavy edge appears, the edge correction jitter will appear when the pole slice is cut and wound, which will cause the process precision, and will also have a bad effect on the final thickness and morphology of the battery.
l burr：Metal burrs are harmful to lithium batteries. Larger metal burrs directly Pierce the diaphragm, resulting in short circuit between positive and negative electrodes.
l Take off the powder：Electrode powder will affect the performance of the battery, the positive powder, battery capacity is reduced, and the negative powder can not be wrapped when the negative electrode, easy to cause lithium.
4、Characteristics of the equipment：
1. This equipment is designed for continuous slitting and rewinding of positive and negative electrode pieces after intermittent coating in the production of lithium ion battery.
2, unwinding using air expansion shaft, magnetic powder brake constant tension control, photoelectric correction control.
3. The slip axis is adopted to ensure that the tension of each strip is the same after cutting, and each strip is completely synchronized. Continuous cutting will not cause belt breaking. Servo motor is adopted for material receiving, smooth operation and low noise, which can ensure high precision cutting and rewinding.
Winding tension is automatically tracked and detected and adjusted on the touch screen, so the tension is uniform and stable. Winding tension, slitting speed and slip shaft pressure are all set on the touch screen.
4, the slitting knife shaft is installed on the cart, can prepare different slitting width knife rest; When slitting is needed, the tool rest is pushed to the slitting machine and slitting is carried out after mechanical positioning (the positioning process is very simple). Avoid cutting different width, frequently adjust the trouble caused by the tool, but also improve the service life of the tool, easy to operate.
5. Active traction is controlled by servo motor, winding is controlled by Mitsubishi inverter and PLC program.
6, cutting with blade roller cutting mode, especially suitable for intermittent coating after the cutting, cutting after the edge of the piece without burr.
7. Dust brush, fan dust blowing system, certain dust and impurities may be produced during the operation of the machine, resulting in pole piece pollution. Equipped with dust brush and dust blowing function to effectively solve quality problems.
8. The frame is equipped with a coiling change support platform, which is convenient for both ends to be bonded when coiling change and effectively improve the efficiency of coiling change.
