Bopp Adhesive Tape Making 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.

2. Lack of composite professional talents who understand manufacturing technology and process and know cutting process
In the manufacturing process of the slitting machine, different customers are often faced with different materials and requirements. If different manufacturers produce the same materials, the raw materials used are not the same chemical plant products, and the physical properties of the materials produced are not the same. When producing the slitting machine, it cannot be generalized. In the production process, the manufacturing process will change, especially in the size of the roll diameter and the thickness of the coating layer, the difference between the active roller and the passive roller and the wrap angle of the roller surface, etc. The lack of corresponding research talents in the field often leads to many waste products and defective products in the slitting process. Such composite talents should not only be familiar with the design and manufacturing process of the entire slitting machine, but also understand the different characteristics of different materials during slitting. Currently, it is very scarce in China, which leads to the current situation of domestic slitting machines.

3. Lack of insight into the characteristics of different materials at the time of slitting, distinguishing between control systems and structures
Everyone knows that the physical properties of different materials are inconsistent. Some materials are smooth and firm. Some materials are very soft and soft, and the physical properties of the same material with different thicknesses are not the same. Among the slitting machines, the structure is also different, and there is a lack of changes in the control system due to its structural changes. The difference is rarely studied. In particular, the change in the difference in the control curve is even less known, and its mature control system software is still very few in China. Although some people have tried the application of a slitter control software, the chances of success are very low. Most of them are characterized by “headaches and pains.” Although our company has experienced 7-8 years of hard work, Some experience has been gained and the control system is becoming more mature, but there is still a certain gap compared with the materials covered by well-known foreign brands.
