Reasons, countermeasures and effects of BOPP film slitting quality ---
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.
The basic knowledge of the slitting machine and its development process --
Basic knowledge and development of slitting machine
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.
Domestic cutting machine development status and outlets ---
three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
2. Automation control part: At present, the automation level of the slitting machine produced in China is still at the middle and lower level. Although the domestic control of the original device has been widely used and the price is lower, the domestic slitter manufacturers are far away in use. It lags behind the level of developed countries, especially in the control system, and the lack of organic combination with the structure of the slitting machine and the material to be cut. At this level, most of the domestic slitting machines still stay on the thick lines. The rigor and rationality of the cutting machine control system has not been fully understood. I personally think that the domestic slitting machine manufacturers should start from the above several directions, and find out the method that meets the cutting and cutting principle of the slitting machine and can maximize the use of the functions provided by the hardware.
