[0034] Reference below Figure 1-Figure 4 The high-definition four-sided glue-free composite embossing structure according to the embodiment of the utility model is described.

[0035] like Figure 1-Figure 4 As shown, the high-definition four-side glue-free composite embossing structure is mainly used in the embossing folding device 100, including a composite flat roller 210 and a composite flower roller 220. Specifically, the composite flat roller 210 is rotatably arranged in the embossing folding device 100, the roller surface of the composite flat roller 210 is smooth, and the composite flower roller 220 is rotatably arranged on one side of the composite flat roller 210, the composite flower roller 220 and the composite flat roller 210 form a paper inlet 201 above, the roller surfaces of the composite flower roller 220 and the composite flat roller 210 are attached to form an embossing area 202, and the paper enters the embossing area 202 from the paper inlet 201 and is pressed against the two rollers to form a pattern.

[0036] Specifically, the composite flat roller 210 and the composite pattern roller 220 are both steel roller structures, which can emboss patterns on the paper entering the embossing area 202. The composite pattern roller 220 is provided with a dot-shaped boss 221, a strip-shaped boss 222 and a pattern boss 223. The strip-shaped boss 222 is arranged around to form a four-sided enclosed area 203, and the dot-shaped boss 221 is located in the enclosed area 203. In order to firmly emboss the multi-layer paper without glue to avoid separation, the dot-shaped boss 221 and the strip-shaped boss 222 emboss the four sides of the paper to form the enclosed area 203, thereby realizing the four-sided embossing operation. The pattern boss 223 is embossed in the enclosed area 203, and the pattern of the pattern boss 223 can help to press the middle area of ​​the paper to prevent looseness.

[0037] In order to make the paper glue-free composite more firm, the surfaces of the dot-shaped boss 221, the strip-shaped boss 222 and the pattern boss 223 are all provided with raised dot-shaped locking bosses 225, and the width of the dot-shaped locking bosses 225 is between 0.1 mm and 0.4 mm.

[0038] In this embodiment, the width of the dot-shaped locking edge boss 225 is 0.1 mm to 0.2 mm, and may also be 0.1 mm, 0.2 mm, or 0.3 mm according to actual needs.

[0039] The dot-shaped locking edge boss 225 in this embodiment is not limited to a circle, and the dot-shaped locking edge boss 225 can be etched into different shapes according to actual production requirements, such as a triangle, a rhombus, a square, etc. The utility model does not elaborate on the shape of the dot-shaped locking edge boss 225 one by one, and it should be understood that, without departing from the basic concept of the utility model, the shape of the dot-shaped locking edge boss 225 can be flexibly changed, and it should be regarded as within the protection scope defined by the utility model.

[0040] Specifically, the dot-shaped edge-locking bosses 225 are arranged at a certain density on the corresponding boss surfaces, and a plurality of tiny compression textures are formed on the paper under the hard pressure of the composite pattern roller 220 and the composite flat roller 210, so that the firmness of the paper is further improved.

[0041] This embodiment uses two steel rollers to press against each other, which exerts greater pressure on the paper, making the pattern clearer, the pattern resolution can reach 4K level, and the appearance is more beautiful. The dot-shaped locking edge boss 225 of the composite flower roller 220 further presses the pattern, making the pattern of the paper clearer and the paper not easy to separate.

[0042] When multiple layers of paper are pressed against the composite flower roller 220 and the composite flat roller 210, the multiple layers of paper will be compounded together and the patterns on the composite flower roller 220 will be embossed to achieve the effect of locking the edges on all four sides. Due to the limitations of process and durability in traditional processes, the etching depth of the boss of the composite flower roller 220 cannot be too shallow, so the diameter and width of the boss cannot be too small, which affects the firmness of the composite and the clarity of the pattern. The embossed paper is prone to stratification, unclear patterns, and especially poor clarity of the pattern on the back of the paper, which affects the consumer's experience. The utility model solves the technical problems of easy stratification of embossed paper, unclear embossed patterns, and poor clarity of the pattern on the back of the paper. The paper embossed using the glue-free composite embossing structure of this embodiment is not only firmly compounded, but also can achieve a 4K-level resolution embossing effect, greatly improving the aesthetics of the paper.

[0043] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the composite pattern roller 220 is further provided with a text boss 224 . The text boss 224 and the pattern boss 223 are both arranged in the enclosed area 203 . The surface of the text boss 224 is provided with a dotted edge-locking boss 225 .

[0044] Specifically, a text boss 224 is further provided on the composite pattern roller 220 , and the text boss 224 and the pattern boss 223 simultaneously form a text and pattern pattern in the enclosed area 203 .

[0045] In other embodiments, the styles of the dot-shaped bosses 221, the strip-shaped bosses 222, the pattern bosses 223 and the text bosses 224 can be etched into different patterns and designs according to customer requirements. It should be understood that, without departing from the basic concept of the utility model, the styles of the dot-shaped bosses 221, the strip-shaped bosses 222, the pattern bosses 223 and the text bosses 224 can be flexibly changed, and all should be considered within the protection scope defined by the utility model.

[0046] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the line width of the text boss 224 and the pattern boss 223 is 0.6mm. In this embodiment, the line width of the text boss 224 and the pattern boss 223 is 0.6mm, and the dot-shaped locking edge boss 225 forms a plurality of dot-shaped locking edges with a diameter of 0.1mm to 0.2mm within the embossed line, thereby improving the composite firmness of the paper. In other embodiments, the line width of the text boss 224 and the pattern boss 223 can be adjusted according to actual production needs to ensure that the embossing formed by the dot-shaped locking edge boss 225 is within the line.

[0047] In some embodiments of the present invention, Figure 2-Figure 4As shown, the strip-shaped bosses 222 are staggeredly arranged on the surface of the composite pattern roller 220 and distributed around the periphery of the enclosed area 203 to form a locking edge with a width of 10 mm to 20 mm.

[0048] Specifically, in the present embodiment, the width of the pattern printed by the strip-shaped boss 222 is 19 mm, the patterns of the strip-shaped boss 222 are arranged perpendicular to each other, and the dot-shaped locking edge boss 225 forms a plurality of dot-shaped locking edges in the pattern of the strip-shaped boss 222 .

[0049] In some embodiments of the present invention, Figure 2-Figure 4 As shown, a dot-shaped boss 221 is disposed at the junction of the strip-shaped boss 222 and the enclosed area 203 , and the strip-shaped boss 222 and the dot-shaped boss 221 form a double stamping on the periphery of the enclosed area 203 .

[0050] Specifically, the patterns on the paper are stripe boss 222 patterns, dot boss 221 patterns and enclosed area 203 from outside to inside, while pattern boss 223 patterns and text boss 224 patterns are evenly distributed in enclosed area 203, forming a firm embossing effect from four sides to inside, highlighting the pattern and text patterns, making the paper full of three-dimensional sense.

[0051] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the height of the dot-shaped locking edge boss 225 is higher than the heights of the dot-shaped boss 221 , the strip-shaped boss 222 , the pattern boss 223 and the text boss 224 .

[0052] Specifically, during the pressing process of the composite pattern roller 220 and the composite flat roller 210, the dot-shaped locking edge boss 225 contacts the roller surface of the composite flat roller 210 to generate huge pressure, so that the patterns of the dot-shaped boss 221, the strip-shaped boss 222, the pattern boss 223 and the text boss 224 are printed on the paper with clearer texture and more three-dimensional pattern.
