Second, the use of procedures;
1. Check whether the parts of the machine are loose due to transportation and other reasons, adjust the four foot screws of the machine, and verify that the machine is level on the ground.
2. External high-pressure gas is supplied to the pressure regulating valve. The purpose of the second air pipe blowing is to eliminate the residual nozzle in the empty groove at the lower right of the drum, so that the drum can smoothly accept the new nozzle and adjust the pressure of the pressure regulating valve. The best use.

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,
Methods include:

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.

Reasons, countermeasures and effects of BOPP film slitting quality ---

Eight. Indentation
There are two reasons for the cause of film roll indentation. One is caused by the winding wheel of the film forming process, and the other is caused by the cutting factor. The reasons for the cutting are:
1 Due to the poor adjustment of the angle of the puller wheel, the pressure and tension of the puller wheel are concentrated on one point of the film, and the friction of the contact point causes damage to the film surface to form an indentation.
2 The winding roller is damaged, such as scratches, etc., the degree of film roll indentation is large when the scratch is longitudinal; 3 The winding roller is contaminated, causing the surface of the pressure roller to be uneven, such as adhesive tape, impurities, etc. It will also cause the film roll to be indented and the press roll must be cleaned.
Slight indentation does not affect the use of the product, but it affects the appearance of the product, causing the customer to doubt the quality of the product; the obvious indentation not only affects the appearance of the product, but also attenuates the corona value of the film, affecting the film. Processing performance.
