Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 1 and 2, the embossed sheet of the present invention includes a substrate 10, a flexible material layer 20 disposed on one side of the substrate 10, and a color coating layer.
The flexible material layer 20 is a thermoplastic material, such as a polyvinyl chloride layer, and a plurality of first protruding structures 21 are protrudingly disposed on a side of the flexible material layer 20 away from the substrate 10.
The first top surface 211 of the first protruding structure 21 away from the substrate 10 is a first upper color surface parallel to the substrate 10, at least one side of the first protruding structure 21 is provided with a first step 212 in a protruding manner, and a second step 213 is provided outside the first step 212 and at a position close to the substrate 10 in a protruding manner. The side surfaces of the first step 212 and the second step 213 far from the substrate 10 are both planes parallel to the substrate 10, or the side surface of the first step 212 far from the substrate 10 is a plane parallel to the substrate 10 and the side surface of the second step 213 far from the substrate 10 is an inclined surface inclined relative to the substrate 10. At least one step-shaped plane or one inclined plane is arranged between the adjacent first protruding structures 21, so that the pattern is stronger in layering sense and more obvious in stereoscopic sense. The second step 213 of the inclined plane can improve the viewing angle of the stereoscopic pattern, and the pattern without the inclined plane can not show the stereoscopic effect after being changed to a certain angle, but only shows a planar pattern.
The bottom of the adjacent first projection structures 21 have a connection surface 214 therebetween.
The side of the first steps 212 remote from the substrate 10 forms a second coloring surface, the side of the second steps 213 remote from the substrate 10 forms a third coloring surface, and the connecting surfaces 214 form a fourth coloring surface.
The upper color layer includes a first upper color layer 31 disposed on the first top surface 211 and a plurality of second upper color layers 32 disposed on the second to fourth upper color surfaces.
When the side surfaces of the first step 212 and the second step 213 far away from the substrate 10 are all planes parallel to the substrate 10, the first top surfaces 211 of the first protruding structures 21 are in the same plane, the side surfaces of the first step 212 of the first protruding structures 21 far away from the substrate 10 are in the same plane, the side surfaces of the second step 213 far away from the substrate 10 are in the same plane, and the connecting surfaces 214 are in the same plane. The same color is printed on the coloring surface at the same height to form the same layer of the pattern, so that the pattern has stronger layering and more obvious stereoscopic impression.
When the side surface of the second step 213 far from the substrate 10 is an inclined surface disposed obliquely with respect to the substrate 10, the first top surfaces 211 of the plurality of first protruding structures 21 are in the same plane, the side surfaces of the plurality of first step structures 21 far from the substrate 10 are in the same plane, the lower ends of the second step 213 far from the side surface of the substrate 10 are in the same plane, the upper ends of the second step 213 far from the side surface of the substrate 10 are in the same plane, and the plurality of connecting surfaces 214 are in the same plane.
The height between the top and the bottom of the protruding part of the existing embossed sheet is 30-35 threads, namely 0.30-0.35 mm, the depth of the gap between the adjacent protruding parts is too deep, the pigment is difficult to enter the bottom of the protruding part of the embossed sheet, and the white leaving phenomenon is easily caused. In the present embodiment, the height h between the first top surface 211 and the connecting surface 214 of the first protrusion structure 21 is 18 to 25 threads, i.e., 0.18mm to 0.25 mm. This reduces the depth of the gap between adjacent first projection structures 21, facilitating the coloring in the gap between adjacent first projection structures 21.
The distance between the connection surface 214 and the side surface of the second step 213 far from the substrate 10 (or the distance between the connection surface 214 and the lower end of the side surface of the second step 213 far from the substrate 10), the distance between the side surface of the second step 213 far from the substrate 10 and the side surface of the first step 212 far from the substrate 10 (or the distance between the upper end of the side surface of the second step 213 far from the substrate 10 and the side surface of the first step 212 far from the substrate 10), and the distance d1 between the side surface of the first step 212 far from the substrate 10 and the first top surface 211 are all 5-8 filaments, that is, 0.05-0.08 mm. Therefore, different coloring surfaces have specific height difference and cannot interfere with each other when being respectively colored.
The width d from the first coloring surface to the fourth coloring surface is 4-6 filaments, namely 0.04 mm-0.06 mm. This makes the first to fourth coloring surfaces have appropriate widths to retain the coloring material. If the width of the upper colored surface is too small, it will retain little color and be insufficient to provide visual effect. If the width of the upper color surface is too large, the pattern is rough and not fine.
The first and second upper color layers 31 and 32 are transferred onto the first to fourth upper color surfaces by an upper mold. A part of the colorant enters the gap between the adjacent first projection structures 21 and remains on the second to fourth coloring surfaces.
Referring to fig. 3, the precision embossing roller for PVC sheet top printing provided by the present invention includes a cylindrical embossing roller body 100, a plurality of second protruding structures 110 protruding from the circumferential surface of the embossing roller body 100, the end of the second protruding structure 110 is a second top surface 111 and corresponding to a connecting surface 214, the side of the second protruding structure 110 corresponds to a second step 213 and is provided with a third step 112, and the side corresponds to a first step 212 and is provided with a fourth step 113.

The height Gh between the second top surface 111 and the end molding surface 114 of the second projection structure 110 is 18 to 25 filaments, i.e., 0.18 to 0.25 mm.
Since the dimensions of the end molding surface 114, the fourth step 113 and the second top surface 111 are much smaller than the patterned roller body 100, a straight line instead of an arc line can be used for approximate calculation when calculating the surface lengths of the end molding surface 114, the fourth step 113 and the second top surface 111, wherein the distance Gd of the adjacent second protrusion structures 110, i.e., the width of the end molding surface 114, is 4-6 filaments, i.e., 0.04 mm-0.06 mm. The widths of the fourth step 113, the third step 112 and the second top surface 111 are all 4-6 threads, namely 0.04 mm-0.06 mm.
