Description

Technical Field

[0001] The utility model relates to the technical field of calendering equipment, in particular to a calendering roller group. Background Art

[0002] Traditional plastic decorative panels are generally produced using calendering. The calendering process involves pressing and stretching the plastic to a specific thickness and shaping the surface. The shaping process is primarily performed by a calendering roller assembly. This assembly consists of two calendering rollers, forming a calendering gap between them. At least one of the calendering rollers has a calendering texture applied to the surface. As the hot-melt plastic passes through the calendering gap, the calendering texture is transferred to the melt. Once the melt cools, a plastic decorative panel with a specific surface texture is formed.

[0003] Currently, imitation rattan decorative panels are available on the market. Adding them to solid wood furniture can create a more harmonious visual effect. However, these panels are currently produced using injection molding, which has issues such as high production costs and limited product size. While using calendering to produce these panels would significantly reduce production costs, existing technologies lack calendering rollers for this purpose, necessitating improvements.

[0024] The following describes the embodiments of the present invention in detail.

[0025] In this embodiment, unless otherwise expressly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are for the purpose of better explaining the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0026] The utility model provides a rolling roller group, such as Figure 1 As shown, it comprises two rollers 1 arranged in parallel, with a rolling gap formed between the two rollers 1, and a rolling texture 11 is provided on the outer surface of at least one of the rollers 1. Figure 2 As shown, the pressed texture 11 is configured to include a rattan-like depression 2 that is recessed from the outer surface of the roller 1 and a plurality of raised platforms 3 surrounded by the rattan-like depression 2, and the raised platforms 3 are spaced a certain distance from the other roller 1. In actual production, the outer surface of at least one of the rollers 1 is provided with a pressed texture 11, so that the decorative board is formed into a product with a flat one side and an imitation rattan structure on the other side; of course, the outer surfaces of both rollers 1 can also be provided with a pressed texture 11, so that the decorative board is formed into a product with an imitation rattan structure on both sides, but it is necessary to make the pressed structures of the two rollers 1 move precisely relative to each other and synchronously, which requires a high degree of accuracy of the equipment. However, inspired by this embodiment, whether the outer surface of one or both rollers 1 is provided with a pressed texture 11 should fall within the scope of protection of the present utility model.

[0027] In order to conveniently display the pressed texture 11, Figure 2 and Figure 3 They are respectively a partial top view and a partial three-dimensional schematic diagram after the rolled texture 11 is flattened. Figure 2 and Figure 3As shown, the rattan-like depression 2 forms a plurality of rattan-like nodes 21, each rattan-like node 21 includes two transverse grooves 211, two vertical grooves 212, two 45° oblique grooves 213 and two 135° oblique grooves 214. In the circumferential direction, the two 45° oblique grooves 213 and the two 135° oblique grooves 214 are evenly distributed around the circumference to form a windmill shape. The end of each 45° oblique groove 213 is connected to the middle of the vertical groove 212, and the end of each 135° oblique groove 214 is connected to the middle of the transverse groove 211; the raised platform 3 is octagonal, and the rattan-like node 21 is spaced apart from the raised platform 3 in the transverse and vertical directions.

[0028] By means of the above-mentioned structural arrangement, the plastic melt can be stretched and pressed onto the plastic melt after passing through the stretching gap, thereby forming a decorative board with a specific texture. Specifically, in this embodiment, during stretching, the concave wicker-like depression 2 can form a pattern on the decorative board. Figure 5 The wicker-like raised structure 41 shown in FIG. 4 and the raised platform 3 can be formed on the decorative plate as shown in FIG. Figure 5 The light-transmitting area 42 shown is concave relative to the wicker-like raised structure 41, and as a whole forms a Figure 5 The imitation rattan decorative panel 4 shown. In this embodiment, the rattan-like raised structure 41 constitutes the imitation rattan structure. In a real rattan structure, the rattan strips would form through holes, which also contribute to the visual beauty of the rattan structure. However, it is difficult to form a regular hollow structure in the middle of the panel during rolling production. To this end, in this embodiment, a raised platform 3 is provided at a certain distance from another roller 1, but the height of the raised platform 3 is higher than the rattan-like depression 2. During rolling, the thickness of the light-transmitting area 42 rolled out by the raised platform 3 is thinner than the thickness of the rattan-like raised structure 41. This enables different areas of the entire imitation rattan decorative panel 4 to have different light transmittances. Specifically, the light-transmitting area 42 has a high light transmittance, while the rattan-like raised structure 41 has a low light transmittance. This makes the entire imitation rattan decorative panel 4 display a layered color difference, which makes the imitation rattan decorative panel 4 have a better visual effect.

[0029] In this embodiment, the minimum spacing between the raised platform 3 and the other roller 1 is 0.4-2mm, preferably 0.5mm, which corresponds to the thickness of the light-transmitting area 42; the lowest point of the rattan-like depression 2 is 1-4mm lower than the raised platform 3; preferably 1mm, and the sum of this size and the size of the raised platform 3 is the thickness of the rattan-like raised structure 41, that is, the thickness of the rattan-like raised structure 41 is preferably 0.5+1=1.5mm. After testing, the imitation rattan decorative board 4 produced within the above preferred size range meets the decorative use requirements, and due to its thin thickness, small material consumption, low production cost, and high consumer acceptance. Of course, the above size can be increased, so that the total thickness of the imitation rattan decorative board 4 can be 2-5mm, which is also possible to meet different usage requirements.

[0030] In the embodiment, as shown in Figure 4 The top surface of the convex platform 3 is provided with a plurality of convex points 31 arranged in a horizontal and vertical array, and the convex points 31 are spaced apart from the other roller 1. The convex points 31 are arranged on the top surface of the convex platform 3, that is, the thickness of the embossing structure corresponding to the convex points 31 is thinner than the thickness of the embossing structure corresponding to the convex platform 3, and the light transmittance is better. Based on the above structure, as shown in Figure 6 The convex points 31 form light-transmitting pits 421 in the light-transmitting area 42 during embossing, and the existence of the light-transmitting pits 421 reduces the material contained in the light-transmitting area 42, increases the light transmittance of the light-transmitting area 42, and further highlights the existence of the rattan-like convex structure 41 and the rattan texture under the contrast of the stronger light-transmitting difference. Preferably, the minimum spacing between the convex points 31 and the other roller 1 is 0.2-1mm. Through the above arrangement, the thickness of the material below the light-transmitting pits 421 is only 0.2-1mm, the light transmittance is large, but it can also meet the strength requirements of the rattan-like decorative plate. Preferably, the convex points 31 are quadrangular pyramids. Preferably, the width of the convex points 31 is 0.8-1.2mm. The shape and size parameters arranged meet the demand of increasing light transmittance and also meet the strength requirements of the rattan-like decorative plate.

[0031] In the embodiment, the widths of the horizontal grooves 211, the vertical grooves 212, the 45° inclined grooves 213 and the 135° inclined grooves 214 are equal and are 2.5-3.5mm, preferably 3mm; the length and width of the convex platform 3 are equal and are 6-8mm, preferably 7mm. It has been tested that the rattan-like decorative plate 4 produced based on the structure with the above size range has the best simulation effect and excellent visual effect.

[0032] In summary, the embossing roller set can solve the problem that there is no embossing roller set for producing a rattan-like decorative plate in the prior art, and the use effect and visual effect of the produced rattan-like decorative plate are better.

[0033] In the case of no conflict, the above embodiments and features in the embodiments can be combined with each other.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
