In the modern packaging industry, the slitting machine is a relatively important equipment that is often used before and after printing. The raw materials are mainly cut before printing, such as paper, plastic film and so on. This is a process that raw material manufacturers must complete in order to meet the width requirements of packaging manufacturers such as customers. The slitting machine is used to divide the printing and composite film of a plurality of sets of patterns of a fixed width into a finished film roll to adapt to the subsequent automatic packaging and bag making process.
        With the improvement of flexible packaging automation and consumer goods manufacturers focusing on reducing the inefficiency and pollution of intermediate links, some manufacturers have gradually changed the process and replaced manual packaging with more automated automatic packaging lines. As the demand for coils continues to increase, the position of the slitter is becoming more and more important, and higher requirements are placed on the efficiency of the slitter.
        When it comes to the efficiency of the slitter, many people think that the efficiency of the slitter is only related to the speed of the slitter. Actually, I think that the efficiency of the slitter is related to the following factors: slitting speed, finished product. Rate, non-operation time, stability, etc. Although the cutting speed is an important indicator of the working efficiency of the slitting machine, if the yield is low, not only will the work efficiency of the whole machine be low, but also the cost will increase. Similarly, if the non-operation takes a long time, such as: adjusting the machine, setting the tool, changing the tool, refueling, connecting the joint, changing the volume, processing the problem, etc., it takes a long time to improve the speed of the slitter, and it makes no sense. It is. Not to mention the stability of the slitting machine, not only will it affect the working efficiency of the slitting machine, but also affect the quality of the product, and it will cause trouble and unnecessary waste to the next process. Therefore, the efficiency of the slitter is a comprehensive concept.

        In the process of slitting, the stable tension system is an important indicator to ensure the quality of the product. It controls the mutual tension between unwinding, drawing, slitting, winding, etc., so that the slitting material is always in the cutting process. A steady state. If the tension is properly controlled, it can avoid the deformation and drift of the raw materials during the process of speeding up and slowing down the machine. Generally, the unwinding tension is slightly larger than the sum of the reel tensions. Most of the previous slitting machines use magnetic powder clutch to control the tension, but the magnetic powder clutch speed can not be high. It is easy to cause high-speed friction of the magnetic powder during operation, which causes high temperature and shortens its life. In severe cases, it will be stuck and the machine operation will be blocked. With the development of science and technology, the use of servo drive technology, most of them now use vector variable frequency motor to control the tension system of the slitting machine. The automatic detection of the pendulum roller makes the man-machine interface intuitive, the tension system is more stable and reliable, and easy to operate.
