In the modern packaging industry, the slitting machine is often used before and after printing a more important equipment, the main pre-press slitting raw materials, such as paper, plastic film and so on. This is the raw material manufacturers in order to adapt to the max-width='100%' width requirements of customers and other packaging manufacturers and must complete a process. The most widely used printing and composite after the cutting process, the use of cutting machine will be a fixed max-width='100%' width of the multi-group pattern of printing, composite film slitting for the finished film rolls to adapt to the back of the automatic packaging and bag making process.
With the increase in automation of flexible packaging, as well as consumer goods manufacturers focus on reducing inefficiencies and pollution in the intermediate stages, some manufacturers are gradually changing the process to a higher degree of automation of the automatic packaging line instead of manual packaging. With the increasing demand for rolls, the position of the slitter is becoming more and more important, which puts higher demands on the efficiency of the slitter.
Speaking of the efficiency of the slitting machine, many people think that the efficiency of the slitting machine is only related to the speed of the slitting machine, in fact, I think the efficiency of the slitting machine is related to the following factors: slitting speed, yield, non-running occupancy time, stability and so on. Slitting speed is certainly an important indicator of the efficiency of the slitting machine, but if the yield is low, not only will cause the machine's efficiency is low, but also will cause the cost of rising. Similarly, if the non-running occupies a long time, such as: adjusting the machine, knife, knife change, change material, connectors, change the volume, deal with the problem of time-consuming, purely to improve the speed of the slitting machine, there is no meaning. The stability of the slitting machine, not to mention, will not only affect the efficiency of the slitting machine, but also affect the quality of the product, but also to the next process will cause trouble and unnecessary waste. So the efficiency of the slitting machine is a comprehensive concept.
In the slitting process, a stable tension system is to ensure product quality is an important indicator, which controls the unwinding, traction, slitting, rewinding and so on between the mutual tension, so that the slitting material in the slitting process is always in a smooth state. If the tension is properly controlled, the raw material can be avoided in the process of machine speed up, speed down deformation, drift and other phenomena. General unwinding tension is slightly greater than the sum of the winding shaft tension. Most of the previous slitting machines use magnetic particle clutch to control the tension, but the magnetic particle clutch speed can not be high, easy to cause high-speed friction in the operation of the magnetic powder, resulting in high temperatures, shortening its life, and in severe cases will be jammed, so that the machine operation is blocked. With the development of science and technology, the use of servo drive technology, now most of the vector frequency conversion motor to control the tension system of the slitting machine, the use of automatic detection of the pendulum roller, man-machine interface is intuitive, the tension system is more stable and reliable, easy to operate.
