Description

Technical Field

[0001] This utility model relates to the field of embossing technology for household paper tissues, and in particular to a four-sided embossing assembly. Background Technology

[0002] Currently, four-sided embossing typically uses a pair of integral rollers (one pattern roller and one smooth roller). This requires very high precision control over the rollers (medium to high) and pressure, and it is difficult to guarantee a clear and uniform embossing across the entire surface. This results in high costs and difficulties in operation and debugging.

[0003] One existing technology for four-sided embossing assembly is that traditional four-sided embossing is completed by a pair of integral rollers, one pattern roller and one smooth roller. However, due to the rigidity of the rollers and the fact that the pressure is applied to the rollers at both ends, the rollers must have a sufficiently large diameter. The smooth roller must be processed according to the pressure curve. The pressure curve requires high processing precision, which is extremely difficult to control, resulting in high debugging difficulty and high cost. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high debugging difficulty and high cost caused by the rigidity of the roller and the fact that the pressure is applied to both ends of the roller in the existing technology. This is because the roller must have a sufficiently large diameter, and the smooth roller must be processed according to the pressure curve with high precision, which is extremely difficult to control. The proposed invention is a four-sided embossing assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a four-sided embossing assembly, including an assembly support frame, on both sides of one end of the assembly support frame are four-sided embossing rollers, and embossing roller support beams are installed at the four corners of the two four-sided embossing rollers. An embossing roller base plate is installed at one end of the embossing roller support beam, and an embossing roller body is installed inside the embossing roller base plate. Four paper guide rollers are installed at one end of the assembly support frame.

[0006] Preferably, the outer wall of the four-sided embossing roller is equidistantly distributed with multiple embossing patterns, and the main body of the embossing roller is divided into multiple steel sleeve embossing units that match the embossing patterns.

[0007] Preferably, a fixing frame is fixed on both sides of the top of the assembly support frame, an unfolding roller assembly is installed on one end of each of the two fixing frames, a felt roller body is installed below the unfolding roller assembly on one end of each of the two fixing frames, and a felt roller pressurizing cylinder connected to the felt roller body is installed on one end of each fixing frame.

[0008] Preferably, a pressurized airbag is installed inside the support beam of the embossing roller, and a pressure adjustment mechanism is installed inside the bottom plate of the embossing roller.

[0009] Preferably, an oiling felt assembly is installed at one end of the assembly support frame above and between the two four-sided embossing rollers.

[0010] Preferably, a cleaning brush roller assembly is installed at one end of the assembly support frame, located below the middle of the two four-sided embossing rollers.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention employs a segmented unit paper web embossing mechanism to address manufacturing and debugging difficulties, reduce costs, and extend service life. Multiple steel-sleeved embossing units within the embossing roller body correspond one-to-one with the embossing patterns on the outer wall of the four-sided embossing roller. Each steel-sleeved embossing unit is solely responsible for embossing the four sides of one sheet of tissue paper. A pressure-pressurizing airbag within the embossing roller support beam provides uniform pressure. Fine-tuning via a pressure adjustment mechanism ensures that each steel-sleeved embossing unit applies uniform linear pressure to the paper web, eliminating the need to overcome the high elastic deformation within the overall roller and resolving the issue of adjusting the clarity and uniformity of the embossing on a pair of rollers. There is no need to consider the height of the roller curve or the adjustment of pressure. Each steel sleeve corresponds to one sheet of tissue paper, ensuring consistent line pressure. The line pressure is reduced from 450KN / M for the original integral roller to 280KN / M, extending service life. The segmented unit paper web embossing mechanism eliminates the influence of the integral roller's high pressure, simplifying debugging and lowering the technical threshold. Each segment can be adjusted independently, with each tissue paper having its own independent segmented steel sleeve embossing unit. All tissues are pressurized uniformly using pressure airbags, resulting in uniform embossing across the entire sheet. Because the pressure of the segmented unit paper web embossing mechanism acts directly on the roller surface, it eliminates the need to overcome the pressure of the roller's high elastic deformation, resulting in less pressure. This eliminates the need for a hydraulic station and the cost of an integral roller, reducing costs by 50% or less. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

Embossing roller support beams 7 are installed at the four corners of the two four-sided embossing rollers 6. An embossing roller base plate 16 is installed at one end of the embossing roller support beam 7. An embossing roller body 14 is installed inside the embossing roller base plate 16. Four paper guide rollers 11 are installed at one end of the assembly support frame 1.

[0017] The overall effect of Embodiment 1 is that multiple steel sleeve embossing units within the embossing roller body 14 correspond one-to-one with the embossing patterns 17 on the outer wall of the four-sided embossing roller 6, with each steel sleeve embossing unit responsible for embossing the four sides of a single sheet of tissue paper. The pressure airbags 13 within the embossing roller support beam 7 provide uniform pressure, which is finely adjusted by the pressure adjustment mechanism 15, ensuring that each steel sleeve embossing unit applies uniform linear pressure to the paper web without needing to overcome the high elastic deformation within the overall roller.

[0018] Example 2, as Figure 1-3 As shown, multiple embossing patterns 17 are evenly distributed on the outer wall of the four-sided embossing roller 6. The embossing roller body 14 is divided into multiple steel sleeve embossing units that match the embossing patterns 17. The top two sides of the assembly support frame 1 are fixed with fixing frames 2. The unfolding roller assembly 3 is installed at one end of each of the two fixing frames 2. The felt roller body 4 is installed below the unfolding roller assembly 3 at one end of each of the two fixing frames 2. The felt roller pressurizing cylinder 5 connected to the felt roller body 4 is installed at one end of the fixing frame 2. The pressurizing air bag 13 is installed in the embossing roller support beam 7. The pressure adjustment mechanism 15 is installed in the embossing roller base plate 16.

[0019] The effect achieved by the entire embodiment 2 is that multiple steel sleeve embossing units inside the embossing roller body 14 correspond one-to-one with the embossing pattern 17 on the outer wall of the four-sided embossing roller 6, and each steel sleeve embossing unit is responsible for the four-sided embossing of a sheet of tissue paper. The pressure airbag 13 inside the embossing roller support beam 7 provides uniform pressure. The pressure adjustment mechanism 15 makes fine adjustments so that each steel sleeve embossing unit applies uniform linear pressure to the paper web without having to overcome the high elastic deformation of the overall roller. During the embossing process, the upper lubrication felt assembly 9 continuously applies lubricating medium to the embossing pattern 17 of the four-sided embossing roller 6 to reduce friction between the pattern and the paper and avoid paper jams or pattern wear. The lower cleaning brush roller assembly 10 cleans the residual paper dust and impurities on the surface of the embossing pattern 17 in real time to ensure the clarity of the embossing. Before entering the embossing area, the paper is guided by the paper guide roller 11 on the assembly support frame 1 and first spread out by the unfolding roller assembly 3 to avoid wrinkles affecting the embossing effect. At the same time, the felt roller body 4 is pressed against the paper web by the felt roller pressure cylinder 5 to help smooth the paper surface and perform preliminary cleaning.
