Description

TECHNICAL FIELD

[0001] The utility model relates to digital film transfer printing technical field especially relates to a textile digital color hot stamping and gold stamping integrated printing production line. BACKGROUND

[0002] The film transfer printing of digital printing is widely used, especially in the field of color hot stamping and gold stamping. However, the traditional color hot stamping and gold stamping process is often carried out independently, and the color and gold stamping processes need to be nested, which is difficult to nest accurately, resulting in a series of problems such as multiple production steps, poor nesting effect, complex composite design process, slow speed, low efficiency and the like. This separate processing method not only increases the production time and affects the overall production capacity, but also increases the production cost to a certain extent, which restricts the market competitiveness of the production enterprise. Therefore, it has become an urgent demand in the industry to seek a method that can effectively integrate the color hot stamping and gold stamping processes, so that the complex color and gold stamping composite design can be easily realized.

[0003] In addition to the above efficiency and cost problems, the traditional gold stamping process also has other significant defects. For example, in the traditional gold stamping process, a layer of primer is usually printed first, then the hot stamping of the aluminum layer is carried out, and finally a layer of varnish is applied. Although this process can provide protection to a certain extent, the application of varnish is usually carried out by means of engraved mold or silk screen, which is complicated and requires multiple nesting, which will result in insufficient metal texture and errors in color and gold stamping nesting. In addition, the complexity and multiple steps of this process further increase the technical requirements and difficulty of production.

[0004] Finally, the traditional gold stamping or flocking process is usually carried out directly on a white background, which makes the exposed white background particularly conspicuous once the gold stamping or flocking layer falls off, thereby significantly affecting the overall appearance of the product. This not only affects the aesthetic appearance of the product, but also may cause negative user experience for consumers. Therefore, exploring an innovative process that can solve these defects has become a technical problem that needs to be solved in the current industry.

[0027] In order to make the technical personnel in the field better understand the technical scheme of the utility model, the utility model is further explained in detail below in combination with the drawings and specific implementation.

[0028] As Figures 1-6 Indicated, the utility model discloses a textile digital color hot stamping and gold stamping integrated printing production line, which comprises a UV printing device, an automatic powder scattering and shaking device and a drying device. The utility model can print color pattern (color UV ink, white UV ink, simulated color UV ink) and gold stamping gloss oil together by using UV printing device 1, then automatically scatters and shakes powder and removes the excess hot melt powder of PET transfer film by automatic powder scattering and shaking device 2, finally, hot melt powder is heated and melted into hot melt adhesive by drying device 3 and is cooled, so that the production of transfer film can be completed. Therefore, the utility model can realize the synchronous printing of color hot stamping area and gold stamping area, and the printing speed is fast and the efficiency is high.

[0029] Among them, the UV printing device 1 is equipped with UV curing lamp 11 and at least three independent printing heads, and is color printing head 12 for printing color UV ink and simulated color UV ink, white printing head 13 for printing white UV ink and gloss oil printing head 14 for printing gold stamping gloss oil.

[0030] The UV printing device 1 in the application, the UV curing lamp 11 is used to produce ultraviolet rays, and the ultraviolet rays are irradiated on the ink to make the ink solidify instantaneously. Generally, the UV curing lamp 11 adopts a specific ultraviolet wavelength to ensure the optimal solidification effect of the ink. The color printing head 12 is used to print color UV ink and imitation color UV ink, and the color printing head 12 can print a color pattern. The white printing head 13 is used to print white UV ink, and the white printing head 13 can print a white base color on other colors, and the white base color can be used as a background color for the colors, and the white base color can be solidified by the UV lamp to achieve the effect of adhering the hot-melt powder.

[0031] The textile digital color hot stamping and gold stamping integrated printing production line can greatly reduce the production steps and time and improve the production efficiency.

[0032] In the textile digital color hot stamping and gold stamping integrated printing production line, the gold stamping varnish can be directly printed on the PET transfer film by the UV printing device 1, and in addition to the simple and convenient manufacturing process, the high-precision metal texture pattern and text, that is, the high-precision and high-quality gold stamping, can be obtained.

[0033] The UV printing device 1 is used to print the color pattern (color UV ink, imitation color UV ink and white UV ink) and the gold stamping varnish, and the two pressing and stamping processes are performed, so that the hot stamping and gold stamping effects are fine and firm and not easy to fall off.

[0034] The textile digital color hot stamping and gold stamping integrated printing production line uses a transfer film to perform gold stamping and hot stamping. Figure 6 As shown in the drawing, the transfer film comprises a color hot stamping area and a gold stamping area, the color hot stamping area comprises, from bottom to top, a PET transfer film, a color UV ink layer, a white UV ink layer and a hot-melt powder layer, and the gold stamping area comprises, from bottom to top, a PET transfer film, a gold stamping varnish layer, an imitation color UV ink layer and a hot-melt powder layer. The color UV ink layer, the white UV ink layer, the imitation color UV ink layer and the gold stamping varnish layer are printed by a UV printer (for example, the UV printing device 1) and solidified by a UV lamp.

[0035] Therefore, the transfer film has the following advantages: first, easy to produce, the color hot stamping area and the gold stamping area are independent of each other, and can be printed by using a UV printer in one step, and then only need to sprinkle hot melt powder and then press and hot stamp the hot stamping and gold stamping in sequence to complete the transfer, and the production process is simple; second, compared with the traditional transfer film which needs to be separately subjected to color hot stamping and gold stamping, the transfer film can simultaneously realize color hot stamping and gold stamping, the production process is simple, the production cost is lower, and the production speed is faster, and is beneficial to realize batch production.

[0036] Further, the color of the imitation color UV ink layer and the color of the gold stamping paper subjected to gold stamping treatment should be consistent or have similar color tones. In addition, this principle is also applicable to the color of the flocking paper subjected to flocking treatment. Taking gold as an example, if the color of gold stamping is set to gold, then gold or a color tone close to gold should also be preferentially considered in the selection of the imitation color. Such a design concept aims to effectively avoid the aesthetic problem caused by the falling off of gold stamping. Once the gold stamping layer falls off, the exposed imitation color is consistent with the color of the gold stamping area, and almost does not have a negative impact on the overall visual effect, thereby ensuring that the visual effect of the product always remains coordinated and beautiful. Such a design not only improves the durability of the product, but also effectively prolongs the service life, and ensures that consumers can always enjoy a high-quality visual experience during use.

[0037] Further, the PET transfer base film comprises a release film layer. Generally, the release film layer is composed of silicon dioxide, polyethylene terephthalate resin B (that is, a PET film), triethylvinyl antimony oxide and silicone oil. The release film layer forms a thin release layer on the PET film, and the release layer has good high-temperature resistance and release property, facilitating tearing off the PET film after hot stamping.

[0038] Further, the gold stamping gloss oil is composed of a photoinitiator TPO (that is, 2,4,6-trimethylbenzoyl phenyl phosphonic acid ethyl ester), trimethylolpropane triacrylate, dipropylene glycol diacrylate, 2-phenoxyethyl acrylate, ethoxyethoxyethyl acrylate, propylene glycol dilaurate and polyurethane acrylate. The gold stamping gloss oil of the utility model is oily and not water-soluble, and the gold stamping gloss oil is directly printed on the release layer by using a UV printer. After the gold stamping paper is covered, hot stamping is performed, so that the gold stamping layer is attached to the gold stamping gloss oil layer, and the gold stamping layer is relatively firm and the gold stamping pattern is relatively detailed.

[0039] In addition, since the gold stamping gloss oil layer has high light transmittance, the strength and color of the metallic texture can be adjusted by controlling the thickness and transparency of the gloss oil.

[0040] Further, the automatic powdering and shaking device 2 comprises an automatic powdering mechanism 21 for uniformly powdering hot melt powder on the hot PET transfer film, and a shaking mechanism 22 for shaking off the excess hot melt powder.

[0041] Further, the drying device 3 comprises a drying tunnel 31 for baking the hot melt powder on the PET transfer film, and an air cooling assembly 32 for cooling the baked PET transfer film, and the drying tunnel 31 is connected with a drying machine 33.

[0042] It is worth noting that the automatic powdering and shaking device 2 and the drying device 3 can be integrated in the same equipment.

[0043] The color stamping area and the gold stamping area in the utility model do not coincide, and the color stamping area and the gold stamping area are independent of each other, and the transfer film manufacturing process is as follows: printing on the PET transfer base film by using a UV printer, printing the gold stamping varnish in the gold stamping area first, then printing the color UV ink layer in the color stamping area, printing the imitation color UV ink layer in the gold stamping area, and then printing the white UV ink layer in the color stamping area and the gold stamping area. During the printing process, the UV lamp needs to be irradiated to realize the semi-curing of the ink. Finally, the hot melt powder is scattered, the excess hot melt powder is shaken off, then the hot melt powder is heated into a hot melt adhesive layer and all the inks are completely cured, and the manufacturing of the transfer film is completed.

[0044] The subsequent transfer process is as follows: the transfer film is inverted and placed on the printing material (such as clothes), then the transfer film is pressed and ironed by using the transfer film machine, the pattern on the transfer film is transferred to the printing material, that is, the stamping. After stamping, the PET transfer base film is torn off after cooling. Then cover the gold stamping paper, and perform the second pressing and ironing by using the transfer film machine, and then tear off the gold stamping paper after cooling to complete the gold stamping.

[0045] During the process of transferring the stamping picture to the printing material, the hot melt powder layer is connected to the printing material by hot pressing, after the PET transfer base film is torn off, the gold stamping layer is attached to the gold stamping varnish layer by covering the gold stamping paper and hot pressing. Or, after the PET transfer base film is torn off, the flocking layer is attached to the gold stamping varnish layer by covering the flocking paper and hot pressing, thereby forming a flocking area.
