High Quality Automatic Tape Slitter Machine
Causes, countermeasures and effects on the quality of BOPP film slitting quality ---
two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)
Through many years, the BOPP industry has carried out a series of intensive and meticulous work on solving the problem of wrinkling. From the two aspects of process parameter screening and equipment adjustment and transformation, we have found a set of effective solutions and received very good results. effect,
5 Under the same parameters, the long gauge is more likely to wrinkle than the short gauge film roll, which means that the longer the specification, the worse the exhaust effect, and the lower the strength of the long gauge paper tube, the slitting process paper The slight bending of the tube tends to cause the film in the middle of the film roll to wrinkle for a long time, and when the paper core is long, under the high-speed rotation of the slit, as the axis of the film winding, its straightness, concentricity, strength, The indicators such as surface finish are the most important. Generally speaking, the longer the paper core, the more difficult it is to ensure the straightness and concentricity. Therefore, the quality of the paper core is very important. It is necessary to improve the inspection of the paper core. If the paper tube is found during the slitting process, the paper tube is found. The quality is abnormal and needs to be replaced in time. In addition, under the same parameter conditions, the short gauge is more prone to deviation than the long gauge membrane coil, and a large winding pressure is required. Therefore, for the adjustment of the wrinkle, the wrinkle can be reduced by appropriately reducing the pressure setting for the long specification, and the pressure is increased for the short specification to prevent the deviation;
6 Different thickness films have different degrees of wrinkling, thick film stiffness is better, less wrinkles, thin film is more open, so the thin film should be adjusted to increase the strength of the parameters to overcome For the generation of wrinkles, different thickness of the film should have different special data for slitting;
7 The product that is slit inside and outside the slitting machine may have different degrees of wrinkling due to the different angles (wrap angles) entering the winding roller. The difference between the inner and outer wrinkles of each slitting machine should be compared, such as The difference is obvious. During the slitting process, the specification that is prone to wrinkle should be cut on the side that is not prone to wrinkle;
8 The wrinkle reduction can also be achieved by adjusting the venting performance of the pressure roller and improving the stability of the winding arm.

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.
