Slitting machine operating procedures -

Second, the volume of the replacement of the finished product (operating station)

8. Operate the button on the winding arm to wind up the paper core.
9. Manually cut the film to be cut onto the corresponding rewinding paper core. After tightening the film, it is firmly adhered to the paper core (note that the side 1 and side 2 films are differently worn).
10. After all the paper cores on both sides are glued, press “Crop 1 Clamp” and “Reel 2 Clamp” at the same time, and then press “Rewind side 1 open” and “winding side 2 open” at the same time. The position is automatically swung until the winding paper core is pressed against the upper roller, the winding main body is started, and the film is slowly wound until it is tight. (The two-button white indicator light turns from blinking to steady light)
11. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.

12. The main operator shall check the winding condition of each film and fine-tune the winding arm if necessary.

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 ---

four. Deviation
Deviation refers to the phenomenon that part of the film on the end face of the film roll is misaligned, which is caused by the sliding of the film during the winding process.

2. Causes and countermeasures of deviation:
(1) The problem of the quality of the slitting in the same category as the deviation of the end face is, in terms of degree, the degree of misalignment is more serious than the misalignment of the end face; in terms of nature, the general end face is not a continuous problem. However, the deviation is mostly an accidental problem; from the analysis of the reasons, the cause of the unevenness of the end face may cause the occurrence of the deviation problem.
(2) Since the deviation of the deviation from the end face is more prominent, the eye point should be placed in the fine point when the end face is not aligned. When analyzing the deviation problem, the eye point should be widened, especially the factor of the cutting speed. The effect is that the acceleration and deceleration are too rapid. For a film with good smoothness, it is easy to cause slippage and cause a split layer, and the slitting speed should be slowed down.
(3) For products with narrow slitting, too tight winding of the film roll will cause the film to slip laterally. If the film roll is too loose, air will be trapped, which will cause the film roll end to be staggered. Roll tension.
