Transparent Packing Tape Slitting Machine

Transparent Packing Tape 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.

Reasons, countermeasures and effects of BOPP film slitting quality ---

 

six. Burr

The raw edge product not only affects the appearance, but also directly affects the use. The edging product is observed with a magnifying glass. The edge of the film is jagged. The film roll is prone to breakage during use, and the consequences are very serious. For example, if the printed film breaks during the printing process, the ink will be caused. Splash, need to clean the machine and the ground, and then lead the film, re-coloring and other processes, production of physical and working loss; if the tape film breaks during the coating process, it is necessary to open the oven more than ten meters, re-introduction Membrane, turn off the oven, heat up and reproduce. These are things that users are very annoying and we must pay attention to.

In addition, we must pay attention to the protection of the end face during the moving process of the film roll, the film end face gap caused by the operation accident, and the gap has high concealment, the problem is difficult to find and flow to the user, the product will be Use has a greater impact.

Seven. Sharp edge
The curling occurs at the edge of the film winding, which causes the curling. The reason is that the edge of the thick film is curled up and the edge part is lifted up; the second is that the winding is too tight, and the tension can be shortened by slitting. Speed ??to improve the resulting edge curling phenomenon; third, the cutter is too blunt, and the stretching phenomenon occurs at the slit when slitting, causing the edge of the film roll to be turned outwards after winding to cause the curling edge, and the cutting should be replaced in time. The knife can avoid the occurrence of the curling problem; the fourth is that the tool is not installed correctly, such as the blade is close to the edge of the sipe and the blade is passivated. Cutting with a round knife can improve the curling of the film roll.
In the use of the unwinding process, there will be different degrees of side-floating in the unwinding process, and it is impossible to track the alignment with the electric eye, which directly affects the use effect. Therefore, it is necessary to change the product with the curled edge.
