The A4 paper slitter is a mechanical cutting device that cuts wide sheets of paper or film into a plurality of narrow-width materials, and is commonly used in papermaking machinery and printing and packaging machinery.

A4 paper slitting machine consists of frame, transmission system, receiving and discharging machinery and tension control device, traction member, slitting bracket, waste winding and discharging device. It divides the raw materials into several independent units. The working principle is to fix the raw materials on the discharge and the end of the discharge shaft is equipped with a magnetic powder tension controller to constant the tension required by the raw materials, and then towed by a pair of rubber rollers. Raw materials are cut into several pieces by a blade. Then, the guide rollers are guided to the A and B winding reels to wind up the finished product. Its transmission is driven by the main motor to drive the rubber roller and the receiving shaft to run synchronously to achieve the purpose of pulling the material and receiving the finished product.

The web slitting machine is a powerful one in the reel cutting equipment. It has the characteristics of stable operation, convenient operation, high speed, high precision, strong adaptability and high output. It is used in papermaking, paper trade and printing industry. widely.
The core mechanism of the web slitter becomes the unwinding section, including the unwinding, pulling and slitting sections. Unwinding is a passive unwinding by pulling. The web slitter requires extremely high traction and slitting.

DC servo motor control for web slitter The common deviation control system has gas-liquid and photoelectric servo control systems. Both work the same way, the only difference is the difference in the detection device. The former is a pneumatic detecting device and a gas and liquid servo valve, and the latter is a photoelectric detecting device and a DC servo motor. They have their own strengths.

Web paper slitting machine is widely used in cardboard, coated paper, kraft paper, cultural paper, double adhesive tape, high gloss photo paper, gold and silver cardboard, aluminum foil paper, laser laser paper, tobacco and alcohol packaging paper, etc. The cutting machine is a high-efficiency, high-precision, high-stability paper-cutting machine for paper processing. It is a paper processing machine commonly used in the paper industry and printing industry.
