Description
Technical Field
The invention relates to the technical field of PVC film processing, in particular to a high-efficiency PVC film winding method.
Background
The soft PVC film coiled material has the increasing demands in the aspects of windows such as off-road vehicles, yachts, tents and the like due to light weight, high cost performance, impact resistance, high transparency, high light transmittance, adaptation to high and low temperature environments and the like. The product is mostly smooth on two sides, and the thickness is mostly 300-1500 um. In order to avoid interlayer air inclusion during film coiling, a high-temperature pressurizing coiling mode of 50-80 ℃ is adopted, meanwhile, in order to ensure that the cut is smooth during splicing, a multi-purpose storage rack of a manufacturer stops the splicing mode, and the traditional mode of coiling is to glue paper on paper cores or adopt a highly smooth plastic core to finish the splicing process.
Because the two surfaces of the soft PVC film are smooth, if the paper core is used in roll-changing splicing, the paper core (comprising special polished paper core) is difficult to automatically roll up. At present, a smooth plastic transparent adhesive tape is wound on the surface of the plastic transparent adhesive tape to reduce the surface roughness of the contact core layer. In theory, the smooth plastic core is similar to the paper core wrapped by the plastic tape, and is easy to splice, but the plastic core is expensive, so that the plastic core is abandoned by manufacturers. When the roll is changed, under the action of pressure, the soft film is pressed to the smooth roll core, and the film is wound on the paper core due to low friction coefficient between interfaces so as to complete the splicing process. However, the adhesive tape is wound manually, and there are inevitable micro wrinkles and splice openings in the process, and the surface is uneven in microscopic terms. When the flexible film is extruded, uneven marks are printed on the product against the winding core. Meanwhile, no matter the paper core wraps the plastic transparent adhesive tape or the plastic core, the adhesive force between the plastic and the PVC film is large, the sliding friction is small, and once the film contacts with the winding core, the film is fixed, is difficult to slide and flatten, and generates wrinkles. The wrinkles and the uneven marks of the adhesive tape are memorized on the PVC macromolecules, and are difficult to eliminate in the use process of downstream customers, and defective products are generated, so that the coiled core products have to be scrapped.
