Description

Plastic floor with synchronized pattern

This creative department belongs to the creation of a plastic floor, in particular to a plastic floor made of a synchronized flower system with a pattern of flowers.

According to the use of plastic materials to make the floor to replace the natural wood, reducing the damage to natural materials, is the trend of the development of today's plastic flooring products, one of the plastic floor surface pattern has a embossed three-dimensional effect, deeply loved by consumers. As can be seen from the prior art, the existing plastic floor surface overlay printing film and wear-resistant film are mainly realized by three-roll calendering or six-roll calendering, or artificially collating in a laminated manner. Manually waste raw materials and increase labor. In the first two ways, when the substrate and the printing film are not synchronized in the production process, since the transmission speed of the substrate and the printing film cannot be adjusted to realize the synchronous transmission of the two, it is easy to cause the substrate and the printing film to be pressed together. Misalignment occurs, not only the pattern is blurred, but also the protruding or concave portion of the original pattern can not accurately correspond to the mold pattern on the rolled pattern roll, resulting in a three-dimensional pattern on the finished plastic floor and on the printed film. The pattern pattern has no alignment, which has a great influence on the aesthetic appearance of the plastic floor.

The main purpose of this creation is to provide a "plastic floor with synchronized pattern" which is used to form the pattern, molding and pattern on the printed layer when the substrate, printed layer and wear-resistant laminate of the plastic floor are formed. The three-dimensional embossing on the substrate and the wear layer can accurately align the aligned pattern of the flower pattern and enhance the three-dimensional pattern effect of the plastic floor.

Due to the above-mentioned creative purpose, the creation of the "plastic floor with synchronized pattern" is to continuously transport the film of the substrate, the printing layer and the wear layer to a four-roll calender integrated press type into a plastic floor. The finished product has a pattern of flowers, wherein the substrate is integrally formed by co-extrusion, at least a soft layer and a hard layer having different softness. The printed layer is formed on the upper edge surface of the substrate, and the surface is printed with a predetermined pattern or texture, and the pattern or the texture is designed to have an unspecified convex portion and a concave portion, and the wear layer is formed of a transparent material. On the printed layer. The pair of flower patterns are combined with a synchronous flowering system by using the four-roll calender, and the pattern or texture of the printed layer is roll-formed on the wear layer and the substrate according to the design of the convex portion and the concave portion. The four-roll calender is provided with two conveying rollers arranged in an upright direction, a mirror roller and a pattern roller. The pattern roller is formed with the same embossing pattern as the printing layer pattern or texture, and the embossing is performed. According to the design corresponding to the convex portion and the concave portion, corresponding concave embossing and convex embossing, through the synchronization of the flowering system, so that the substrate is integrated with the printing layer and the wear-resistant laminate, The convex portion of the pattern or the texture corresponds exactly to the concave embossing, and the concave portion corresponds to the convex embossing accurately, and presents a composition structure of the flower pattern.
