Description

Four-side embossing device suitable for household paper Technical Field The utility model relates to the technical field of paper towel production equipment, in particular to a four-side embossing device suitable for household paper. Background In the field of paper for daily use, the quality and appearance design of paper-extracting products are becoming important factors for consumers to choose from as an indispensable part of our daily life, and from napkin paper, toilet paper to facial tissues, the seemingly trivial products often bring unexpected surprise to innovations in detail, wherein the embossing technology is an important means for improving the texture and the aesthetic degree of the paper for daily use, and the development history and market demand change are particularly worth focusing. Four-edge embossing is one of the common technologies of household paper embossing technology, and is characterized in that embossing patterns are generally distributed on the peripheral edges of paper, so that a unique frame effect is formed, the overall aesthetic degree of the paper can be improved, the paper looks more exquisite and high-end, the three-dimensional effect of the paper can be enhanced, and the like. However, the four-sided embossing technology has some limitations that 1) the standard is fixed, the traditional four-sided embossing device adopts a fixed embossing roller set design, so that the standard (such as size, shape, interval and the like) of an embossing pattern cannot be flexibly adjusted, which limits the flexibility of a producer when meeting different market demands, 2) the cost is high, the producer needs to bear high cost when replacing or upgrading the embossing pattern because the traditional four-sided embossing device needs to be provided with a special embossing roller set for each standard embossing pattern, and 3) the production efficiency is limited, and when producing embossed paper products with different standards, the traditional four-sided embossing device may need to replace the whole embossing roller set or carry out complicated adjustment work, which can influence the production efficiency and increase the production period. Accordingly, in order to overcome these limitations and meet market changes and consumer demands, manufacturers are continually exploring and innovating embossing techniques, for example, developing embossing devices with greater flexibility, so that in actual production processes, papers of different embossing types or specifications can be produced with high efficiency, according to the needs of different customers. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a four-side embossing device suitable for household paper, which realizes the rapid switching of different specifications and sizes through the combined design of a main roller and at least two auxiliary rollers and the arrangement of various specification patterns on the printing structures of the auxiliary rollers and the main roller. In order to achieve the aim, the four-side embossing device suitable for the household paper comprises a main roller and at least two auxiliary rollers, wherein the roller surface of the main roller is uniformly distributed with a plurality of pattern convex points, the roller surface of the auxiliary roller is provided with at least two transverse convex points circumferentially distributed at a first rated interval and at least two vertical convex points axially distributed at a second rated interval, any one auxiliary roller can be abutted against or separated from the main roller along the radial direction, the main roller and one auxiliary roller are abutted against and are in rotary butt press fit, and at least one pattern convex point in a superposition area between the transverse convex points and the vertical convex points of the roller surface of the main roller and the auxiliary roller is in periodic embossing fit with the transverse convex points and the vertical convex points of the roller surface of the auxiliary roller. Further, the first nominal spacing between any two of the secondary rollers is the same. Further, the second nominal spacing between any two of the secondary rollers is different. Further, each transverse bulge on the roller surface of the auxiliary roller is a linear bulge structure extending axially. Further, each vertical protrusion on the roller surface of the auxiliary roller is an annular protrusion structure extending in the circumferential direction. Further, the main roller is fixed on the frame, and any one of the auxiliary rollers can be abutted against or separated from the main roller along the radial direction. The utility model adopts the scheme, and has the beneficial effects that: 1) The specification and the size are rapidly switched, namely, through the combined design of the main roller and at least two auxiliary rollers, and the auxiliary rolle
