Transparent Carton Tape Slitter Rewinder

Maintenance and maintenance of the slitter:
     Before use, the main parts of the automatic slitting machine should be inspected and filled with lubricating oil. When inspecting the disassembly and assembly automatic slitting machine, it is strictly forbidden to use unsuitable tools and unscientific operation methods; every two weeks to the machine Make a comprehensive cleaning and inspection; if the automatic slitting machine is stopped for a long time, all the bright surfaces must be wiped clean, coated with anti-rust oil, and covered with a plastic sleeve to cover the whole machine. If the automatic slitting machine is deactivated for more than 3 months, the anti-rust oil should be covered with moisture-proof paper; after the work is completed, carefully clean the equipment, and wipe the exposed friction surface and add lubricant.

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 ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)

With the continuous improvement of slitting technology, the length of wrinkle is becoming less and less, and the products of individual manufacturers have achieved zero wrinkle, which undoubtedly grasps the opportunities in the fierce competition environment. It is worth noting that the wrinkles that we sometimes appear are not caused by the unreasonable setting of the cutting parameters, but because our operators are not responsible for the work, and the film is not attached to the paper tube but is free. After the film is put on the paper tube, it is turned on and cut, and the quality of the wrinkle is artificially created. It must be paid attention to, eliminate the defects of human quality and improve the quality of the product.
