Description
Technical Field
[0001] This utility model relates to the field of paper embossing machinery technology, and in particular to a frame embossing device. Background Technology
[0002] In the household paper market, products such as facial tissues, napkins, toilet paper, and face towels have become necessities in people's daily lives. As consumers increasingly pursue a higher quality of life, the quality and design of household paper products are gradually becoming key factors influencing purchasing decisions. Embossing technology, as an important means of enhancing paper texture and aesthetics, has attracted considerable attention regarding its development and changes in market demand. Existing household paper embossing technologies mainly include two common forms: double-sided embossing and four-sided embossing. The main working principle of embossing technology is to use mechanical pressure to compress multiple sheets of base paper, causing the fibers between the sheets to intertwine, thus forming a glue-free composite.
[0003] Currently, glue-free lamination methods include "point-to-flat" and "point-to-point" glue-free lamination. For four-sided embossing using the "point-to-flat" method, the embossed pattern is distributed around the edges of the paper, creating a unique border effect that greatly enhances the paper's three-dimensionality, making it look more refined and high-end. Traditional four-sided embossing devices typically use fixed embossing roller sets, resulting in inflexible adjustments to the specifications of the embossed pattern, such as spacing, size, and shape. This makes it difficult for producers to quickly respond to diverse market demands. Furthermore, when producing embossed paper products of different specifications and patterns, traditional four-sided embossing devices often require replacing the entire embossing roller set. This necessitates equipping different embossing roller sets with varying specifications and patterns, making the replacement and adjustment process cumbersome. This not only increases costs but also affects production efficiency and extends the production cycle. Utility Model Content
[0004] This utility model provides a frame pattern embossing device, which mainly solves the problem that the existing four-sided embossing device is cumbersome and costly to change the embossing roller group when producing embossed products of different specifications and patterns.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: it includes a horizontal embossing roller and a vertical embossing roller, and a smooth roller is arranged parallel to the horizontal embossing roller and the vertical embossing roller. The horizontal embossing roller and the vertical embossing roller are respectively close to the two sides of the smooth roller. At least two embossing wheels are arranged radially at intervals on the vertical embossing roller. The embossing wheel is composed of at least two arc-shaped protrusions spliced together end to end. At least one horizontal pattern protrusion is arranged axially on the horizontal embossing roller. The interval between each pair of arc-shaped protrusions is equal to the width of the horizontal pattern protrusion.
[0006] In the above technical solution, a more specific solution can be: the horizontal embossing roller and the vertical embossing roller can be interchanged and arranged on both sides of the smooth roller, and the embossed paper strip continuously passes through the horizontal embossing roller / vertical embossing roller, the smooth roller, and the vertical embossing roller / horizontal embossing roller in sequence.
[0007] Furthermore, the two short sides of the arc-shaped protrusion of the embossing wheel are provided with downward-sloping wing plates, which are connected and fixed to the vertical embossing roller by screws.
[0008] Furthermore: the length of the horizontal pattern protrusions on the horizontal embossing roller is equal to the length of the horizontal embossing roller. As the horizontal embossing roller, the smooth roller, and the vertical embossing roller rotate in coordination, the horizontal pattern protrusions of the horizontal embossing roller act on the paper strip to be embossed, forming a horizontal pattern perpendicular to the running direction of the paper strip. The arc-shaped protrusions of the vertical embossing roller act on the paper strip to be embossed, forming at least one equal-length vertical pattern parallel to the running direction of the paper strip on each of its two sides. The length of this vertical pattern is equal to the distance between the two horizontal patterns, and the width of the horizontal pattern is equal to the interval between the two vertical patterns on the same side. A portion of the horizontal pattern fills the gap between the two vertical patterns.
[0009] Furthermore: the diameter of the horizontal embossing roller is equal to the diameter of the vertical embossing roller; at least two horizontal patterned protrusions are axially evenly spaced on the horizontal embossing roller, and the spacing between any two horizontal patterned protrusions is equal to the arc length of the arc-shaped protrusion on the embossing roller; the arc-shaped protrusion on the vertical embossing roller is formed by at least two pieces spliced together end-to-end, and the number of arc-shaped protrusions spliced end-to-end is the same as the number of horizontal patterned protrusions; the horizontal embossing roller and the vertical embossing roller rotate at the same speed.
[0010] Furthermore: the diameter of the horizontal embossing roller is equal to the diameter of the vertical embossing roller, an axially arranged horizontal pattern protrusion is provided on the horizontal embossing roller, and the rotational speed of the horizontal embossing roller is greater than that of the vertical embossing roller.
[0011] Furthermore: the diameter of the horizontal embossing roller is smaller than the diameter of the vertical embossing roller, and a horizontal pattern protrusion is axially arranged on the horizontal embossing roller; the horizontal embossing roller and the vertical embossing roller rotate at the same speed.
[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0013] 1. Because the vertical embossing roller has at least two embossing wheels arranged radially at intervals, the axial spacing of the vertical embossing roller is adjustable. Thus, the axial spacing of the embossed vertical pattern can be adjusted as needed, eliminating the need for equipping embossing roller sets of different specifications, saving costs. Furthermore, since the embossing wheel is composed of at least two arc-shaped protrusions spliced end to end, when adjusting the axial spacing of the embossing wheel as needed, it is only necessary to install multiple arc-shaped protrusions one by one onto the required position on the vertical embossing roller. The installation is simple and easy to operate.
[0014] 2. Since the horizontal embossing roller and the vertical embossing roller are respectively set close to the two sides of the smooth roller, the embossing wheel on the vertical embossing roller is made of at least two arc-shaped protrusions spliced together end to end, and the horizontal embossing roller has at least one horizontal pattern protrusion on the axial direction. When the vertical embossing roller, the smooth roller and the horizontal embossing roller rotate and cooperate to emboss, part of the pattern of the horizontal pattern pressed by the horizontal embossing roller fills the blank space between the two vertical pattern patterns, and the resulting pattern has no overlapping embossing, which is beautiful and elegant.

[0029] like Figure 1The frame embossing device shown includes a horizontal embossing roller 2 and a vertical embossing roller 1. A smooth roller 3 is arranged parallel between the horizontal embossing roller 2 and the vertical embossing roller 1. The horizontal embossing roller 2 and the vertical embossing roller 1 are respectively close to the two sides of the smooth roller 3. The multi-layer paper strip 6 to be embossed first passes through a primary embossing roller group composed of the smooth roller 3 and the vertical embossing roller 1 / horizontal embossing roller 2 for vertical / horizontal embossing, and then passes through a secondary embossing roller group composed of the smooth roller 3 and the horizontal embossing roller 2 / vertical embossing for horizontal / vertical embossing. At least two embossing wheels are arranged radially at intervals on the vertical embossing roller 1. Each embossing wheel is composed of at least two arc-shaped protrusions 4 spliced end to end. At least one horizontal pattern protrusion 5 is arranged axially on the horizontal embossing roller 2. The interval between each pair of arc-shaped protrusions 4 is equal to the width of the horizontal pattern protrusion.
[0030] like Figure 2 In the first embodiment shown, when producing standard-sized napkins, three embossing wheels are radially evenly spaced on the vertical embossing roller 1, arranged on both sides and the middle of the roller. Each embossing wheel is formed by three arc-shaped protrusions 4 joined together end-to-end. Three horizontal patterned protrusions 5 are axially arranged on the horizontal embossing roller 2. The distance between any two arc-shaped protrusions 4 is equal to the width of each horizontal patterned protrusion 5. Multiple layers of paper strips 6 are continuously passed through a primary embossing roller group consisting of the smooth roller 3 and the vertical embossing roller 1 for vertical embossing, and then through a secondary embossing roller group consisting of the smooth roller 3 and the horizontal embossing roller 2. The embossing roller has two short sides with downward-sloping wing plates 4-1, which are connected and fixed to the vertical embossing roller 1 by screws 4-2. The length of the horizontal pattern protrusions 5 on the horizontal embossing roller 2 is equal to the length of the roller. As the vertical embossing roller 1, the smooth roller 3, and the horizontal embossing roller 2 rotate, the arc-shaped protrusions 4 of the vertical embossing roller 1 act on the paper strip 6 to be embossed. After the vertical embossing roller 1 rotates once, three vertical pattern Y2 of equal length parallel to the running direction of the paper strip 6 are formed on both sides and in the middle of the multi-layer paper strip surface to be embossed. Figure 8 As shown; the horizontal pattern protrusions 5 of the horizontal embossing roller 2 act on the multi-layered paper tape 6 to be embossed. The horizontal embossing roller 2 rotates once, forming a second horizontal pattern X2 on the multi-layered paper tape 6, perpendicular to the direction of the paper tape 6's movement. The length of each vertical pattern is equal to the distance between two horizontal patterns, and the width of the horizontal pattern X2 is equal to the distance between two vertical patterns Y2 on the same side. A portion of the horizontal pattern fills the gap between two vertical patterns Y2. The horizontal pattern X2 and the vertical pattern Y2 are arranged alternately on the paper tape to be printed, forming six frame patterns, as shown. Figure 9 As shown.
[0031] In this embodiment, the diameter of the horizontal embossing roller 2 is equal to the diameter of the vertical embossing roller 1, and the rotational speeds of the horizontal embossing roller 2 and the vertical embossing roller 1 are the same. Specifically, as shown... Figure 3 As shown, the two short sides of the arc-shaped protrusion 4 of the embossing wheel are provided with downward-sloping wing plates 4-1. The wing plates 4-1 are connected and fixed to the vertical embossing roller 1 by screws 4-2. When the axial spacing of the embossing wheel needs to be adjusted, it is only necessary to loosen and remove the screws of the original arc-shaped protrusion, then install the arc-shaped protrusion in the required position and tighten the screws. The installation is simple and easy to operate.
[0032] like Figure 4 In the second embodiment shown, when producing large-format patterned paper towels, such as table paper, two embossing wheels are radially evenly spaced on the vertical embossing roller 1, arranged on both sides of the vertical embossing roller. Each embossing wheel is formed by two arc-shaped protrusions 4 joined end-to-end. Two horizontal patterned protrusions 5 are axially arranged on the horizontal embossing roller 2. The distance between any two arc-shaped protrusions 4 is equal to the width of each horizontal patterned protrusion 5. Multiple layers of paper strips 6 to be embossed are continuously... The rollers pass through a primary embossing roller group consisting of a smooth roller 3 and a vertical embossing roller 1 for vertical embossing, and then through a secondary embossing roller group consisting of a smooth roller 3 and a horizontal embossing roller 2 for horizontal embossing. The two short sides of the arc-shaped protrusion 4 of the embossing roller are provided with downward-sloping wing plates 4-1, which are fixed to the vertical embossing roller 1 by screws. The length of the horizontal pattern protrusion 5 on the horizontal embossing roller 2 is equal to the roller length of the horizontal embossing roller 2. As the vertical embossing roller... 1. The rotational cooperation of the smooth roller 3 and the horizontal embossing roller 2 causes the arc-shaped protrusion 4 of the vertical embossing roller 1 to act on the paper strip 6 to be embossed. As the vertical embossing roller 1 rotates once, two equal-length vertical pattern Y1 parallel to the running direction of the paper strip are formed on both sides of the multi-layered paper strip surface. The horizontal pattern protrusion 5 of the horizontal embossing roller 2 acts on the paper strip 6 to be embossed. As the horizontal embossing roller 3 rotates once, two horizontal pattern X1 perpendicular to the running direction of the paper strip 6 are formed a second time on the paper strip 6. The length of each vertical pattern is equal to the distance between two horizontal patterns, and the width of each horizontal pattern is equal to the interval between two vertical patterns on the same side. A portion of the horizontal pattern fills the interval between two vertical patterns. The horizontal pattern X1 and the vertical pattern Y1 are arranged alternately on the printed fabric to form a frame pattern, such as... Figure 5 As shown.
[0033] In this embodiment, the diameter of the horizontal embossing roller 2 is equal to the diameter of the vertical embossing roller 1, and the rotation speed of the horizontal embossing roller 2 and the vertical embossing roller 1 is the same. The two short sides of the arc-shaped protrusion 4 of the embossing wheel are provided with downward-sloping wing plates 4-1, and the wing plates 4-1 are connected and fixed to the vertical embossing roller 1 by screws 4-2; the adjustment and installation methods are the same as in embodiment one.
[0034] like Figure 6 In the third embodiment shown, the diameter of the horizontal embossing roller 2 is equal to the diameter of the vertical embossing roller 1. A horizontal pattern protrusion 5 is axially arranged on the horizontal embossing roller 1. The rotation speed of the horizontal embossing roller 2 is greater than that of the vertical embossing roller 1. By changing the rotation speed, the arc length of the arc-shaped protrusion on the embossing wheel of the vertical embossing roller 1 can be adjusted.
[0035] like Figure 7 In the fourth embodiment shown, the diameter of the horizontal embossing roller is smaller than that of the vertical embossing roller. A horizontal pattern protrusion is axially arranged on the horizontal embossing roller. The horizontal embossing roller and the vertical embossing roller rotate at the same speed. By changing the diameter of the horizontal embossing roller, the arc length of the arc-shaped protrusion on the embossing wheel of the vertical embossing roller 1 can be adjusted.
