1300mm Bopp Tape Slitting Machine

Tape slitting machine feeding, filming and filming
1. Loading: According to the requirements of the cutting plan, according to the driving operation rules, according to the actual situation, hoist the corresponding mother roll on the aging frame, place it on the unwinding unwinding frame according to the inner and outer selection direction of the corona surface, and use the control button Clamp the steel core, leave the steel core support arm and drive.
2. Film penetration: When there is no film on the slitter, the film must be penetrated. Using the slitting machine through the membrane device and the function keys, one end of the original membrane is attached to the membrane chain eyelet, and the membrane button is activated to distribute the membrane along the slitting process to be evenly distributed on each roller.
3. Film: When there is a film on the slitter, when changing the joint, use the vacuum filming table to start the filming station to the working position, manually flatten the film on the first pulling roller of the slitting machine and start the upper vacuum pumping film. Soak the film flat on the filming table, attach the double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding frame and start the lower vacuum pump to make the film flat and absorb the paper. Layer and flatten the adhesive film, the joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps to open the filming station to the inoperative position.

Slitting machine operating procedures -

Third, through the film:

13. 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)

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.
