Description

Imprinting device capable of continuous natural pattern replication {IMPRINTING DEVICE THAT CAN REPLICATE NATURAL PATTERNS CONTINUOUSLY}

The present invention relates to an imprinting device that can continuously and seamlessly reproduce natural patterns on the surface of a board to be imprinted.

Recently, technology has been developed to replicate various patterns on the surface of metal plates used as exterior materials for home appliances, etc. to realize the unique texture and color of metal.

In relation to this, a roll imprinting mold capable of replicating a continuous pattern on the surface of the metal sheet has been proposed.

Specifically, the roll imprinting mold has an engraved or embossed pattern pattern imprinted on the outer peripheral surface, and the roll imprinting mold rotates to replicate a predetermined pattern on the surface of the metal plate.

However, in the conventional roll imprinting mold as described above, if the pattern imprinted on the outer peripheral surface is not a repetitive identical pattern but a natural pattern such as Korean paper, silk, or leather, a seam is bound to occur. There is a problem in that it is difficult to form a natural and continuous large-area natural pattern on the surface of a metal plate due to these joints.

Additionally, it is impossible to apply high stress to a cylindrical mold, such as the roll imprinting mold, during the imprinting process. That is, there is a risk that flattening of the roll may occur in the load concentration area of the roll imprinting mold.

Hereinafter, the configuration and operation of specific embodiments of the present invention will be described in detail with reference to the attached drawings.

Here, in adding reference numerals to components in each drawing, it should be noted that identical components are indicated with the same reference numerals as much as possible, even if they are shown in different drawings.

Figure 1 is a first embodiment of an imprinting device capable of replicating continuous natural patterns according to the present invention, Figure 2 is a diagram showing various natural patterns imprinted on a mold according to the present invention, and Figures 3 to 5 are diagrams showing the present invention. This is a photo substitute for a drawing showing the mold according to and the plate on which the natural pattern is replicated.

Referring to FIG. 1, the imprinting device 1 capable of replicating continuous natural patterns according to a preferred embodiment of the present invention includes a plate-shaped mold 100, an imprinting target plate 200, and a rolling roll 300. It can be included.

A detailed description of the configuration of the present invention is as follows.

First, the mold 100 may be provided with a mold surface 110 having a predetermined pattern 111 formed on at least one surface. For example, the pattern 111 may be a natural pattern of a tactile material such as Korean paper, silk, or leather (see Figure 2). Of course, it is not limited to this and various natural patterns can be selectively applied.

In this case, the mold 100 may be formed in a plate shape of a predetermined length to prevent seams of the pattern 111 from occurring. Accordingly, it may be possible to replicate the continuous pattern 111 in a large area without any seams compared to existing roll-type molds.

Referring to FIG. 3, the mold 100 can be made by using a predetermined length of Korean paper with a natural pattern 111 (see (a) in FIG. 3). That is, the natural pattern 111 implemented on Korean paper is a protruding shape with a predetermined hardness. The natural pattern 111 of the Korean paper may play the same role as the pattern imprinted on the surface of the mold 100. In this way, by using the mold 100 as a fabric of a predetermined length, such as the Korean paper, the separate mold manufacturing process and the costs required for it can be reduced. In addition, the pattern can be continuously copied seamlessly on the imprinting target plate 200 of a predetermined length, which will be described later (see (b) of FIG. 3).

On the other hand, the natural pattern provided on silk or leather (see Figure 2) is protruding, but due to the nature of the material, the hardness is lower than the Hanji pattern. Accordingly, when the silk or leather fabric itself is used as the mold 100, it may be difficult to transfer the corresponding pattern to the surface of the plate 200.

Therefore, in the case of fabrics with low surface hardness, such as silk or leather, natural patterns can be imprinted on the surface of the metal mold 100 through a predetermined natural pattern replication process (Figure 4(a), Figure 5). (see (a)). Since the method of replicating the natural pattern of a fabric and manufacturing it into a metal mold is a known technology, a detailed description thereof will be omitted.

Referring again to FIG. 1, the plate 200 is disposed on one side of the mold surface 110 of the mold 100 provided with the pattern 111, and is pressed into the plate by the pressing force of the rolling roll 300, which will be described later. An imprinting process of the corresponding pattern 111 can be performed on one side of 200 (see Figure 4 (b) and Figure 5 (b)). This plate 200 may be formed to have a length corresponding to the mold 100.

In this case, the plate 200 can be selectively made of metal or synthetic resin depending on the imprinting object desired by the user. In the present invention, an example will be described where the plate 200 is made of stainless steel.

The rolling roll 300 can perform a process of imprinting a pattern 111 on one side of the large-area plate 200 by pressing the other side of the plate 200 toward the mold surface 110 of the mold 100. .

Specifically, the rolling roll 300 may have a structure in which at least one pair is symmetrically spaced apart with the mold 100 and the plate 200 in between, and moves at a predetermined speed by receiving power from a motor (not shown). can be rotated

In the pair of rolling rolls 300, the gap between the rolling rolls 300 is variably adjusted by the operation of an actuator (not shown) depending on the number or thickness of the mold 100 and the sheet material 200 being interviewed. It can be.

Referring to FIG. 6, the surface of the mold surface 110 of the mold 100 provided with the natural pattern 111 may be coated with a protective layer 113 to improve the durability of the pattern 111.

Specifically, the minimum thickness of the protective layer 113 is preferably at least 300 nm, and the maximum thickness of the protective layer 113 is preferably maintained below the maximum height difference of the natural pattern 111.

In this case, the material of the protective layer 113 can be laminated by selectively applying one or more of C, TiN, TiCN, ZrN, ZrCN, CrN, TiAlN, TiAlCN, AlTiN, and AlCrN.

Additionally, before depositing the protective layer 113, a bond layer (Ti, WC, etc.) may be coated on the surface of the mold 100 to improve adhesion.

Additionally, to prevent oxidation of the protective layer 113, an oxide film may be coated on the outermost layer of the mold 100.

The protective layer 113 of this configuration can increase the durability of the continuous natural pattern mold 100, thereby increasing the number of repeated uses of the mold 100.
