Description

Technical Field

[0001] This utility model relates to the technical field of household paper equipment structure, and in particular to a four-sided fixed-grid embossing device for household paper. Background Technology

[0002] In the field of household paper products, facial tissues are an indispensable part of our daily lives, and their quality and appearance design are gradually becoming important factors for consumers when making choices. From napkins and toilet paper to facial tissues, these seemingly ordinary products often bring unexpected surprises through innovation in details. Among them, embossing technology, as an important means to improve the texture and aesthetics of household paper products, deserves special attention for its development history and changes in market demand.

[0003] Traditional four-sided embossing devices often employ a fixed embossing roller design, resulting in a lack of flexibility in adjusting the specifications of the embossed pattern (such as size, shape, and spacing). This limits the flexibility of producers in responding to different market demands. Therefore, to overcome these limitations and meet market changes and consumer needs, producers need to continuously explore and innovate embossing technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tissue paper embossing device that can simultaneously complete four-sided three-dimensional embossing of paper and support quick replacement of vertical rib rollers to achieve multi-specification pattern configuration, thus solving the technical problems of low efficiency and single pattern in traditional equipment.

[0005] To achieve the above objectives, this utility model provides a four-sided fixed-grid embossing device for household paper, comprising a main embossing roller, a horizontal embossing roller adjacent to the surface of the main embossing roller, and at least two sets of vertical embossing rollers with different texture specifications. The surface of the main embossing roller is covered with a plurality of main embossing protrusions; the surface of the horizontal embossing roller is formed with at least one set of horizontal embossing protrusions extending along a parallel axis direction. As the horizontal embossing roller and the main embossing roller rotate and press against each other, the main embossing protrusions in the overlapping area of ​​the horizontal embossing protrusions and the main embossing roller... Points are matched; any group of the vertical pattern rollers can be alternately close to the surface of the main pattern roller; each group of the vertical pattern rollers includes at least two coaxially arranged vertical pattern embossing rollers, wherein each vertical pattern embossing roller has at least two sets of axially spaced vertical pattern protrusions arranged in a ring shape along the circumference of the roller surface; adjacent vertical pattern protrusions in the vertical pattern roller groups of different texture specifications have different spacing configurations; as the vertical pattern embossing rollers and the main pattern roller rotate and press against each other, the main embossing protrusions in the overlapping area of ​​the vertical pattern protrusions and the main pattern roller are matched.

[0006] Furthermore, the vertical embossing roller group and the horizontal embossing roller are arranged sequentially along the rotation direction of the main embossing roller, and each roller surface is close to the roller surface of the main embossing roller.

[0007] Furthermore, the pre-set paper material is fed into the gap between the horizontal embossing roller and the main embossing roller. The horizontal embossing protrusions and the main embossing protrusions are periodically pressed together, thereby periodically forming horizontal embossing patterns arranged at equal intervals on the paper material.

[0008] Furthermore, the pre-set paper material is fed into the gap between the vertical embossing roller and the main embossing roller. The vertical embossing protrusions and the main embossing protrusions are periodically pressed together, thereby continuously forming vertical edging patterns arranged at equal intervals on the paper material.

[0009] The present invention adopts the above-mentioned solution, and its beneficial effects are as follows: 1) Synchronous embossing on four sides: Through the coordinated layout of the main pattern roller and the horizontal and vertical pattern rollers, the three-dimensional embossing on four sides can be completed in a single paper feed; 2) Flexible configuration of patterns: The modular vertical pattern roller group supports quick replacement to meet the differentiated needs of different customers for edge patterns.

[0015] To more fully illustrate this utility model, a detailed description will be provided below in conjunction with the accompanying drawings. The drawings depict preferred embodiments of this utility model. However, it is worth noting that this utility model is not limited to these specific forms and can be implemented in various ways. These embodiments are provided to enable the reader to gain a deeper understanding of this utility model.

[0016] As attached Figure 1-4 As shown in this embodiment, a four-sided fixed-grid embossing device for household paper includes a main embossing roller 1, a horizontal embossing roller 2 close to the roller surface of the main embossing roller 1, and at least two sets of vertical embossing roller groups 3 with different texture specifications. The roller surface of the main embossing roller 1 is covered with a number of main embossing protrusions. The main embossing protrusions can be dot-shaped, line-shaped, or other raised shapes. Their distribution density is determined by the actual pattern requirements. Those skilled in the art can design patterns as needed, and no specific limitations are made here.

[0017] In this embodiment, the horizontal embossing roller 2 is a single shaft structure, and at least one set of horizontal embossing protrusions 21 extending along the parallel axis are formed on the roller surface of the horizontal embossing roller 2. Each set of horizontal embossing protrusions 21 can be a single strip-shaped protrusion structure extending parallel to the axial direction, or it can be a number of dot-shaped protrusion structures distributed parallel to the axial direction. Those skilled in the art can design patterns as needed, and no specific limitations are made here.

[0018] Furthermore, as the horizontal embossing roller 2 and the main embossing roller 1 rotate and press against each other, the horizontal embossing protrusions 21 and the main embossing protrusions in the overlapping area of ​​the main embossing roller 1 are engaged, thereby feeding the preset paper material A into the gap between the roller surfaces of the horizontal embossing roller 2 and the main embossing roller 1. Through the periodic pressing of the horizontal embossing protrusions 21 and the main embossing protrusions, the horizontal embossing patterns A1 arranged at equal intervals are periodically formed on the paper material A. Each horizontal embossing pattern A1 is arranged to extend relative to the direction perpendicular to the conveying direction of the paper material A.

[0019] In this embodiment, each set of vertical embossing rollers 3 includes at least two coaxially arranged vertical embossing rollers 31. Each set of vertical embossing rollers 31 is used in conjunction with each other. Each vertical embossing roller 31 has at least two sets of axially arranged vertical embossing protrusions 311 that extend circumferentially along the roller surface. Each set of vertical embossing protrusions 311 can be a single annular protrusion structure extending circumferentially around the roller surface, or it can be several dot-shaped protrusion structures extending circumferentially along the roller surface. Those skilled in the art can design patterns as needed, and no specific limitations are made here.

[0020] In this embodiment, any set of vertical embossing rollers 3 can be replaced by being close to the roller surface of the main embossing roller 1. That is, in on-site production, a set of vertical embossing rollers 3 with a suitable texture specification is selected according to production needs and replaced by being installed on a preset frame (not shown in the figure). This makes each set of vertical embossing rollers 31 coaxially arranged and close to the roller surface of the main embossing roller 1, so that the preset paper material A can be fed into the gap between the roller surface of the main embossing roller 1 and each vertical embossing roller 31.

[0021] See appendix Figure 3As shown, in this embodiment, the vertical ridge protrusions 311 in the vertical ridge roller groups 3 with different texture specifications exhibit differentiated spacing configurations. That is, the vertical ridge protrusions 311 in each vertical ridge embossing roller 31 of the vertical ridge roller group 3 with the same texture specification are arranged at equal intervals. The size of this spacing is determined by the actual production requirements regarding the paper product specifications. For example, when producing single-sheet paper products with a width specification of 15cm, the axial spacing between any two adjacent vertical ridge protrusions 311 in the vertical ridge roller group 3 is 15cm. However, the spacing of the vertical ridge protrusions 311 in the vertical ridge roller groups 3 with different texture specifications is different. For example, the spacing of the vertical ridge roller group 3 corresponding to the 15cm production requirement is 15cm, while the spacing of the vertical ridge roller group 3 corresponding to the 20cm production requirement is 20cm. By adopting this differentiated spacing configuration, different vertical ridge roller groups 3 can be quickly replaced to meet different production needs, achieving the effect of overall, portable, and rapid replacement of production specifications.

[0022] Furthermore, as the vertical embossing roller 31 and the main embossing roller 1 rotate and press against each other, the vertical embossing protrusions 311 and the main embossing protrusions in the overlapping area of ​​the main embossing roller 1 are engaged, thereby feeding the pre-set paper material A into the gap between the roller surface of the vertical embossing roller 31 and the main embossing roller 1. Through the periodic pressing of the vertical embossing protrusions 311 and the main embossing protrusions, vertical edge pattern A2 is continuously formed on the paper material A with equal spacing. Each horizontal edge pattern A1 is arranged to extend relative to the conveying direction of the paper material A.

[0023] In addition, since at least two vertical embossing rollers 31 are provided on the same vertical embossing roller 31, the number of vertical embossing rollers 31 can be reduced, production costs and the difficulty of replacement and installation can be reduced. At the same time, the vertical embossing rollers 31 made by the roller surface prefabrication method can further improve the embossing accuracy.

[0024] In this embodiment, for ease of understanding, the following explanation will be provided in conjunction with the above-mentioned combination and arrangement of the main pattern roller 1, the horizontal pattern embossing roller 2, and the vertical pattern roller group 3, as well as the specific embossing steps, to further illustrate the four-sided fixed-grid embossing device.

[0025] See appendix Figure 4 As shown, specifically, with the main pattern roller 1 as the reference, the vertical rib roller group 3 and the horizontal rib embossing roller 2 are arranged sequentially along the rotation direction of the main pattern roller 1, and each roller surface is close to the roller surface of the main pattern roller 1. The pre-set paper material A passes through the roller surface gap between the main pattern roller 1 and the vertical rib roller group 3, and the roller surface gap between the main pattern roller 1 and the horizontal rib embossing roller 2 along the roller surface of the main pattern roller 1, so that the paper material A is embossed in sequence to form a vertical edge pattern A2 and a horizontal edge pattern A1. The two patterns are arranged perpendicular to each other, and finally, several grids of four-sided fixed patterns are formed by several vertical edge pattern A2 and horizontal edge pattern A1. Each grid of four-sided fixed patterns corresponds to a paper product.

[0026] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or alterations made by those skilled in the art to the technical solution of this utility model without departing from its scope are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its scope should be covered within the protection scope of this utility model.
