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

Embodiment 1

[0041] Such as Figure 1-4 As shown, the high-precision synchronous pattern embossing system includes a embossing machine and a plate 100 to be embossed, and is characterized in that: the embossing machine includes a frame 1, an upper platen 2, a lower platen 3, and a guide rail 4. The upper pressing plate is connected to the top of the frame through the pressing driving device 5, the lower pressing plate is arranged in the middle of the frame, and the bottom of the frame is provided with a roller 6 matching the guide rail, and the length of the guide rail is greater than or equal to the length of the frame *2, it also includes a frame driving device (not shown in the figure), which is used to drive the frame to move on the guide rail. The concave-convex pattern, the width of the upper platen is equal to or slightly wider than the plate, and the size of the lower platen and the upper platen is slightly larger than that of the upper platen.

Embodiment 2

[0046] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that it also includes a deviation correction device arranged on the lower platen. The deviation correction device is two hydraulic push rods 9 arranged symmetrically. On both sides of the feeding direction of the embossing machine, the image recognition system is located in the middle of the frame above the feeding side of the embossing machine, and the plate to be embossed is provided with a centerline mark on the centerline of the starting position of each unit, so The centerline position of the rack is pre-recorded in the above image recognition system, and the image recognition system sends both the centerline position of the rack and the signal of the centerline mark to the control system, and the control system compares the centerline mark with the centerline position of the rack, and if the centerline If the position of the mark is to the left relative to the center l...

Embodiment 3

[0048] The structure of this embodiment is basically the same as that of Embodiment 2, the difference is that it also includes a heating device (not shown in the figure) for uniformly heating the upper platen, and conventional heating devices can be used, such as electric heating and thermal oil heating.

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...
