Plastic Film Slitting Machine

Plastic Film Slitting Machine

Introduction to slitting machine:
     Slitting machine is a kind of mechanical equipment for slitting wide sheets of paper or film into a plurality of narrow-width materials, which are commonly used in papermaking machinery and printing and packaging machinery.
     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.

Preparation of slitter cutter
1. Razor slitting
1.1. The razor slitting requires the film to travel in the correct direction to the winding section.
1.2. Adjust the photoelectric tracking to bring the film to the proper position.
1.3. Tension the film and attach the blade to the razor holder.
1.4. According to the specifications required by the instruction sheet, the sliding razor holder is cut into the razor groove under the film, and the blade edge and the edge of the sipe are required to be in contact with each other.
1.5 After adjusting the depth of the cutter, lock the razor frame screws.
2. Round knife cutting
2.1. Check whether the upper and lower knives are sharp and have no gaps, and vice versa;
2.2. Determine the number of knives (N+1) according to the number of product series (N);
2.3. Install the lower knife to adjust the width of the lower knife according to the actual width of the product;
2.4 Install the upper knife correctly. The flat side of the upper knife is aligned with the side of the lower cutting edge. The upper knife is aligned with the gap between the lower knife and the septum. Press the screws on both sides to make the upper knife enter the gap depth to about 2mm. The upper knife is attached to the lower knife and fastened. Finally, the screw on the left side of the upper knife holder is adjusted so that the whole knife holder moves 1-2 mm to the right side and is fastened.

Slitting adjustment
1. Put the cutter down, open the curling blower switch, set the winding tension, start the machine, run 2-3 meters, stop;
2. Measure the width of each joint to confirm whether the requirements are met. If there is any error, the ratio of the cutter should be re-matched.
3. Check whether each of the paper cores and the corresponding film are aligned, otherwise adjust them;
