Slitting machine operating procedures -
Third, through the film：
9. Press “Device Jog” again, and the film on both sides will be flattened until the slitting film appears on the winding side 2, and the film is cut with a knife.
10. Manually pull the slit film on the winding side 1 and the winding side 2, bond the film to the corresponding paper core, and tighten the film and stick the flat film to the paper core (note the side 1 and side 2 films). Wearing different methods).
11. Manually adjust the leading edge probe into position.
12. Set the winding length and winding diameter on the operation screen (see the preset length and diameter method for details)
Reasons, countermeasures and effects of BOPP film slitting quality ---
eleven. Width deviation is too large
The width of the film roll is limited by the gap of the sipe roll. The actual slit width will deviate from the width required for the order, but the deviation should be controlled within the tolerance range of ±2mm required by the national standard. The so-called width deviation Large, that is, the actual width of the film roll exceeds the requirements of internal control standards or customer standards.
Not all products have a tolerance of ±2mm, and some customers can only take deviations from the film width, such as the Pd film of Kunshan Zhangpu, the LL film of Shanghai Zhicheng, the PL film of Beijing Amcor, etc. It is required to adjust the film width.

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.
