Description

Technical Field

[0001] The utility model relates to the technical field of thermal sublimation transfer paper, and more specifically to a thermal sublimation transfer paper that is heated evenly. Background Art

[0002] Thermal sublimation transfer technology is a type of transfer printing technology. It uses an inkjet printer equipped with thermal transfer ink to print portraits, landscapes, texts and other images on thermal sublimation transfer paper in a mirror-reversed manner. The thermal transfer ink on the thermal sublimation paper will penetrate into the substrate in the form of vaporization, thereby realistically transferring the image color on the paper to textiles, porcelain cups, porcelain plates, porcelain boards, metals and other materials. Compared with other transfer printing technologies, thermal sublimation transfer equipment requires less investment, has outstanding printing effects, is pollution-free and has low resource consumption.

[0003] At present, the thermal sublimation transfer process is realized through transfer paper. First, the pattern is printed on the thermal sublimation transfer paper using an inkjet printer, and then the pattern of the thermal sublimation transfer paper is transferred to other media by heating. However, in order to improve the heating effect, most of the existing thermal sublimation transfer papers have heat conduction holes on the substrate. The heat conduction holes are usually cylindrical and vertically arranged, and are distributed at intervals. It is difficult to ensure uniformity during heating, which will affect the transfer effect. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a thermal sublimation transfer paper with uniform heating, aiming to solve the problem that most thermal sublimation transfer papers in the prior art have heat conduction holes on the substrate in order to improve the heating effect. The heat conduction holes are usually cylindrical and vertically arranged, distributed at intervals, which makes it difficult to ensure uniformity during heating, thus affecting the transfer effect.

[0006] 2. Technical solution

[0007] In order to solve the above problems, the utility model adopts the following technical solutions:

[0008] A uniformly heated thermal sublimation transfer paper comprises a paper base, a waterproof layer is fixedly connected to the upper end of the paper base, an ink layer is fixedly connected to the upper end of the waterproof layer, an absorption layer is fixedly connected to the upper end of the ink layer, and a plurality of heat conduction holes are opened in the paper base, and the plurality of heat conduction holes correspond to the waterproof layer.

[0009] As a preferred solution of the utility model, each of the heat conducting holes includes a truncated cone opening and a cylindrical opening, the truncated cone opening is opened at the upper end of the paper base and corresponds to the waterproof layer, and the cylindrical opening is opened at the lower end of the paper base and communicates with the truncated cone opening.

[0010] As a preferred solution of the utility model, a plurality of micropores are provided in the ink layer, and the top ends of the plurality of micropores correspond to the absorption layer.

[0011] 3. Beneficial effects

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] 1) In this solution, the ink is absorbed into the ink layer through the absorption layer. The ink layer ensures the uniformity of ink penetration through multiple micropores. The waterproof layer blocks the ink, so that the ink is stable in the ink layer to form a pattern. When the ink pattern is heated and transferred to other media, multiple heat-conducting holes make the waterproof layer evenly heated during the heating process, thereby evenly conducting heat energy to the ink layer. The ink in the ink layer is evenly heated and vaporized to penetrate into the material. After heating, the material molecules in the ink layer wrap the ink for transfer. In the utility model, multiple micropores improve the effect and uniformity of ink penetration. Multiple heat-conducting holes are composed of a truncated cone mouth and a cylindrical mouth to form a trumpet shape, which can improve the uniformity of thermal sublimation transfer paper during heating and ensure the transfer effect.

[0020] Example:

[0021] See also Figure 1 A uniformly heated thermal sublimation transfer paper comprises a paper base 1, a waterproof layer 2 is fixedly connected to the upper end of the paper base 1, an ink layer 3 is fixedly connected to the upper end of the waterproof layer 2, an absorption layer 4 is fixedly connected to the upper end of the ink layer 3, and a plurality of heat conduction holes 5 are opened in the paper base 1, and the plurality of heat conduction holes 5 correspond to the waterproof layer 2.

[0022] In this embodiment, the ink is absorbed into the ink layer 3 through the absorption layer 4 to form a pattern on the thermal sublimation transfer paper. The waterproof layer 2 isolates the ink to prevent the ink from continuing to penetrate into the paper base 1. When the ink pattern is transferred to other media, the entire thermal sublimation transfer paper is attached to the medium and heated by a heating device. During the heating process, the ink pattern is evenly heated and vaporized through the multiple heat-conducting holes 5 on the paper base 1, thereby realizing the transfer of the pattern to other media.

[0023] Specifically, each heat conducting hole 5 includes a truncated cone opening 51 and a cylindrical opening 52 . The truncated cone opening 51 is opened at the upper end of the paper base 1 and corresponds to the waterproof layer 2 . The cylindrical opening 52 is opened at the lower end of the paper base 1 and communicates with the truncated cone opening 51 .

[0024] In this embodiment, when the thermal sublimation transfer paper is heated, the waterproof layer 2 is evenly heated through the cylindrical opening 52 and the truncated cone opening 51, so that the heat energy is evenly conducted to the ink layer 3. The ink in the ink layer 3 is evenly heated and vaporized to penetrate into the material. After heating, the material molecules in the ink layer 3 wrap the ink for transfer.

[0025] Specifically, a plurality of micropores 6 are provided in the ink layer 3 , and the top ends of the plurality of micropores 6 correspond to the absorption layer 4 .

[0026] In this embodiment, the ink can better penetrate into the material molecules of the ink layer 3 through the multiple micropores 6, further improving the thermal sublimation transfer effect.

[0027] Working principle: The ink is absorbed into the ink layer 3 through the absorption layer 4, and the multiple micropores 6 allow the ink to stably penetrate into the material molecules of the ink layer 3 to form a pattern on the thermal sublimation transfer paper. The waterproof layer 2 isolates the ink to prevent the ink from continuing to penetrate into the paper base 1. When the ink pattern is transferred to other media, the entire thermal sublimation transfer paper is attached to the medium and heated by a heating device. During the heating process, the ink pattern is evenly heated and vaporized through the multiple heat-conducting holes 5 on the paper base 1, and penetrates into the material molecules in the ink layer 3. The material molecules in the ink layer 3 wrap the ink for transfer.
