High precision synchronous decorative pattern-aligning embossing system and embossing method

Abstract

The invention discloses a high precision synchronous decorative pattern-aligning embossing system which comprises an embossing machine and a to-be-embossed panel. The system is characterized in that the embossing machine comprises a rack, an upper pressing plate, a lower pressing plate and a guide rail. The upper pressing plate is connected to the top of the rack through a pressing driving device,the lower pressing plate is arranged in the middle of the rack, and a roller matched with the guide rail is arranged at the bottom of the rack. The system further comprises a rack driving device fordriving the rack to move on the guide rail. A concave-convex decorative pattern corresponding to a pattern on the surface of the to-be-embossed panel is arranged on the side, facing the lower pressingplate, of the upper pressing plate, the upper pressing plate is as wide as the panel or is slightly wider than the panel, and the lower pressing plate is equal to the upper pressing plate in size oris slightly larger than the upper pressing plate in size. The invention further discloses a high precision synchronous pattern-aligning embossing method. The clear and stable decorative pattern can beformed on the surface of the panel, and the pattern and the concave-convex decorative pattern are aligned precisely.

Description

technical field [0001] The invention relates to a high-precision synchronous pattern embossing system and a high-precision synchronous pattern embossing method. Background technique [0002] Synchronous alignment has always been a difficult point in the production of plastic sheets. Synchronous matching technology can form concave-convex patterns that match the pattern on the surface of the board, making the pattern more three-dimensional and realistic. The current synchronous alignment technology is mainly realized by multi-roller calendering. During the production process, the transmission of the substrate and the printing film is prone to asynchronous phenomena, resulting in misalignment of the substrate and the printing film. Not only the pattern is blurred, but also the pattern and the concave-convex pattern Mismatch will seriously affect the look and feel of the board. [0003] US patent document US10384427B2 discloses a plastic floor with a printed pattern. The conc...

Problems solved by technology

The disadvantages of this are: 1. The contact time between the pattern roller and the floor is extremely short, resulting in insufficient indentation depth, easy deformation, and easy blurring

Second, the pattern and the pattern deviate

Although the speed difference between the printing layer and the substrate layer can be adjusted by raising the temperature in this application, the printing layer is a very thin plastic film. During the pressing process, the printing layer 12 passes through the first press roller 25 and the feed roller 31 to convey, during this process, the printing layer will be stretched and narrowed, resulting in deformation in both length and width. Even if the registration transfer system can adjust the deviation in length, the deviation in width cannot be avoided , so the final product will deviate from the pattern and the pattern, especially on both sides of the plate, the deviation is serious
