What Is A Slitter?

2019-10-31 16:00   admin

The Slitter Cutter divides a large roll of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into pre-press and post-press equipment of different widths. It is commonly used in papermaking machinery and printing and packaging machinery, paper. The cutting machine series of product processing machinery has a paper slitting machine, a small paper slitting machine, a web slitting machine, a high speed slitting machine, etc.

Metal processing machinery slitting machine: strip slitting machine, copper sheet slitting machine, aluminum sheet slitting machine, stainless steel slitting machine, tinplate slitting machine, etc. The magnetic powder clutch of the previous slitting machine cannot be high.

Because it is easy to cause high-speed friction of magnetic powder during operation, it will produce high temperature, shorten its life, and it will be stuck in serious cases, which will hinder the operation of the machine and bring serious consequences to production. Seriously affected production efficiency. Now it is controlled by double-conversion motor, so that the diameter of the winding material becomes larger and the friction of the magnetic powder is controlled to a certain value. There is no high temperature.

The traditional control scheme of the slitter is to use a large motor to drive the shaft of the rewinding and unwinding. A magnetic powder clutch is added to the reel and reel, and the resistance generated by the magnetic clutch is controlled to control the tension of the surface of the material. . Magnetic powder clutches and brakes are special automatic actuators that transmit torque through the magnetic powder filled in the working gap. The magnetic current can be changed to change the magnetic state of the magnetic powder, and then the transmitted torque can be adjusted. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high speed section fine adjustment and medium and small power speed control system. It is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension control system with a constant tension during winding.

The slitting machine continuously controls from single motor to double motor, and the three motors develop more stable and efficient when the machine speed is faster.

The main feature of the slitter is that the magnetic powder clutch acts as a resistance device and outputs a DC voltage through the system control to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device that can control small tensions.

Disadvantages: The speed is not high, and the high-speed friction of the magnetic powder is easy to occur at high speed, which causes high temperature, which causes the magnetic powder clutch to heat up and shorten its life. The cutter is used to cut a certain width of the web longitudinally and cut into a plurality of devices for narrower slits. After being installed in a unit such as a calender or an extruder or a gluing machine, continuous cutting can be completed, often with a winding device. The knife can be used with a flat knife and a round knife.

The use environment of the slitting machine is that the machine should be installed in a place with proper temperature, dryness, ventilation, good light and convenient operation.

So what are the operational requirements for the slitter? The Slitting Machine Manufacturer will come to tell you.

Features 1. Simple operation control panel: The control of each part of the machine, centralized panel operation.

2, three-stage length setting: advanced three-stage lookup count to ensure accurate winding length.

3. Automatic exchange axis: After the winding operation is completed, the two axes are automatically exchanged, which is easy to operate and high in efficiency.

4. Labeling instructions: Automatically stop after reaching the length of the labeling label, and attach the label marking indicating the film opening on the platform.

5. After feeding mode: the material is fed from the back side of the operation surface, and the rubber pressure roller is attached to reduce the noise of the tearing tape and smooth discharge.

Operational requirements

1. The slitting machine shall carry out fixed length slitting processing of the whole roll or the whole raw material.

2. The fixed length slitting control is divided into static and dynamic slitting.

3. The most important performance indicators for fixed length slitting are the cutting accuracy and the consistency of the finished product length.

4. The slitting length can be set continuously. If there is an error in the actual slitting length, it is easy to calibrate by setting parameters.

The above is about the knowledge of the slitting machine, I hope to help everyone, and if you are interested in the slitting machine, you can contact us is a company specializing in the production of slitting machines, in addition to machine parts including Shear Blade, etc.
