Problems solved by technology

However, among high-end consumer groups, it is hoped that one side of the plastic tablecloth can be printed and the other side embossed at the same time. Using the special light refraction effect of the embossed pattern on the printed pattern, it is expected to produce vivid colors and strong three-dimensional visual effects. , but the existing technology has not been able to solve how to make the printed pattern and the embossed pattern match accurately on the continuous production line to repeatedly produce plastic tablecloths with the same visual effect

Embodiment A

[0019] Such as Figure 4 The structure of the embossed hot pressing roller group shown includes embossed hot rollers 12 and flat rollers 13 of the embossed hot rollers. Airtight cams 14 are provided at both ends of the embossed hot rollers around the roller body.

Embodiment 1

[0021] Such as figure 1 The plastic decorative sheet shown includes a transparent plastic sheet substrate 1, a color print pattern 2 is provided on the front of the substrate, and a concave-convex embossed pattern structure 3 with a line outline corresponding to the front print pattern is provided on the back of the substrate.

[0022] The following examples are based on figure 2 and image 3 Based on:

Embodiment 2

[0024] Such as figure 2 and image 3 As shown, a polyvinyl chloride sheet with a thickness of 0.8 mm is gravure-printed by an embossing roller 4, dried by a drying device 5, and then hot-pressed by a hot-pressing groove 6 to obtain a polyvinyl chloride printing sheet with a registration groove. sheet reprocessing image 3 After being pressed by the alignment roller 7 shown, it is preheated by the preheating device 8, then embossed by the hot pressing roller 9, then trimmed, and finally wound up by the winding shaft 10 to obtain a decorative embossed PVC sheet. The alignment accuracy is less than 0.1mm.

Abstract

The invention relates to a plastic decorative sheet material and a preparation method thereof, and a special wale hot-pressing roller. The sheet material is characterized in that the substrate is a transparent plastic sheet, wherein a color printing pattern is printed on the right side of the sheet; an accidented embossing pattern is hot-pressed on the reverse side with a line profile corresponding to the printing pattern on the right side; and the printing pattern and the embossing pattern at a corresponding position are offset by less than 1 mm. Because of the special light refraction effect of the accidented embossing on the color printing pattern, the plastic decorative sheet material has a vivid color and a strong stereo perception, exhibits a more beautiful visual effect than common planar printed plastic decorative sheet materials and common embossing plastic decorative sheet materials, and is especially suitable to manufacture daily-use decorative products such as tablecloth, dinner pad, table pad, etc.

Description

technical field [0001] The invention relates to a plastic decorative sheet and its preparation method and a special embossed hot pressing roller, more specifically, the invention relates to a printing pattern and a corresponding embossed pattern, vivid colors, A plastic decorative sheet with strong three-dimensional effect and a preparation method thereof belong to the field of daily-use plastic products. Background technique [0002] Transparent plastic sheets such as polyvinyl chloride, polypropylene and polyethylene terephthalate have been widely used in the field of daily products, such as tablecloths, table mats and placemats, among which tablecloths are used in the largest amount. At present, the transparent plastic tablecloth products on the market are roughly divided into two categories: printed tablecloths and embossed tablecloths. Printed plastic tablecloths are generally printed on transparent plastic sheets to make them have patterns and textures of different col...
