[0025] In order to further understand the application content, characteristics and effects of the present application, the following embodiments are exemplified and described in detail as follows with reference to the accompanying drawings.

[0026] Embodiment One:

[0027] Referring to Figure 1 , Figure 1 For the structure diagram of the visual UV ink cartridge in the embodiment, the visual UV ink cartridge in the embodiment includes a transparent ink cartridge body 1 and an ultraviolet-proof film. The ultraviolet-proof film includes a base layer and an ultraviolet-blocking layer. The base layer covers the outer surface of the transparent ink cartridge body 1, and the ultraviolet-blocking layer covers the outer surface of the base layer.

[0028] The visual UV ink cartridge in the embodiment is used for storing UV curing ink. Since the transparent ink cartridge body 1 is made of transparent material, the user can directly observe whether the UV curing ink inside has bubbles, precipitates, stratification, and remaining amount, etc., to avoid printing unqualified ink to the product and to avoid ink breakage during printing, thereby improving the product printing quality and reducing material waste caused by abnormal ink. At the same time, through the setting of the ultraviolet-proof film, external ultraviolet radiation can be effectively blocked from entering the transparent ink cartridge body 1, avoiding the photo-curing of the UV curing ink inside the transparent ink cartridge body 1, and ensuring that the UV curing ink can be stored for a long time.

[0029] Preferably, the ultraviolet-proof film further comprises a protective layer and a reflective layer, the protective layer is covered on the outer surface of the ultraviolet blocking layer, and the reflective layer is arranged between the protective layer and the ultraviolet blocking layer. In specific application, the ultraviolet-proof film in the embodiment is a yellow or tea-colored PI polyimide film, which is a multi-layer structure. Specifically, the ultraviolet-proof film comprises a substrate layer, an ultraviolet blocking layer, a reflective layer and a protective layer which are sequentially stacked. The substrate layer is a PI film, which is used to provide high temperature resistance and mechanical support. The ultraviolet blocking layer is a ZnO ultraviolet blocking layer, which is used to absorb and block ultraviolet rays. The reflective layer is a TiO2 ultraviolet reflective layer, which is used to reflect and block ultraviolet rays. The protective layer is a SiO2 protective layer, which is used to improve the surface hardness of the ultraviolet-proof film and prevent scratching and wear. Specifically, the transparent ink cartridge body 1 is made of high borosilicate glass material. It should be particularly noted that the ultraviolet-proof film in the embodiment is attached to the outer surface of the transparent ink cartridge body 1, and of course in other embodiments, the ultraviolet-proof film can also be sprayed and plated on the outer surface of the transparent ink cartridge body 1.

[0030] Preferably, the transparent ink cartridge body 1 comprises an ink cartridge body and a transparent window arranged on the ink cartridge body, and the ultraviolet-proof film is covered on the surface of the transparent window. It can be understood that the ink cartridge body in the embodiment is not entirely transparent, but has a transparent window, and the remaining part is black and opaque. In this way, the area covered by the ultraviolet-proof film can be saved, and only the transparent window needs to be completely covered. The condition of the UV curing ink inside the ink cartridge body can be directly observed through the transparent window, and the remaining part being black and opaque further improves the UV blocking effect of the ink cartridge body. Specifically, the transparent window can be made of high borosilicate glass material or colorless high-transmittance base material.

[0031] Embodiment two:

[0032] Reference Figure 2 , Figure 2For the structure schematic diagram of the circulating ink supply system in the embodiment, the circulating ink supply system in the embodiment includes a main ink cartridge (not shown in the figure), a nozzle 2, a circulating component 3, and the visualized UV ink cartridge in embodiment one. The transparent ink cartridge main body 1 has an ink inlet interface 11, an ink outlet interface 12, and a circulating interface 13. The main ink cartridge is connected with the ink inlet interface 11. The circulating component 3 includes a circulating driving pump 31 and a circulating pipe. The nozzle 2 has an ink inlet and an ink outlet. The ink inlet of the nozzle 2 is connected with the ink outlet interface 12. The circulating pipe is connected with the ink outlet and the circulating interface 13 respectively. The circulating driving pump 31 is connected with the circulating pipe. In specific application, the circulating ink supply system further includes an ink supply pump (not shown in the figure). The ink supply pump is connected between the main ink cartridge and the transparent ink cartridge main body 1. The ink supply pump draws the ink in the main ink cartridge to the transparent ink cartridge main body 1 through the ink inlet interface 11. The circulating driving pump 31 draws the ink in the transparent ink cartridge main body 1 to the ink inlet of the nozzle 2. The ink flows through the fluid channel inside the nozzle 2. The nozzle 2 extrudes part of the ink from the nozzle hole of the nozzle 2 and forms fine ink droplets to spray on the surface of the target workpiece to form a pattern. At the same time, the remaining ink continues to flow through the fluid channel inside the nozzle 2 to the ink outlet. The circulating driving pump 31 draws the ink at the ink outlet of the nozzle 2 to the transparent ink cartridge main body 1 through the circulating pipe to realize circulating backflow. Thus, a stable ink supply circulating loop is formed to improve the flowability of the ink, avoid the ink from being deposited and layered, and improve the printing quality. Specifically, the outer surface of the main ink cartridge is coated with an ultraviolet-proof film. It can be understood that the main ink cartridge in the embodiment is similar to the visualized UV ink cartridge in embodiment one. The main ink cartridge is also a transparent main ink cartridge coated with an ultraviolet-proof film. Details are not repeated here.

[0033] Reference is made again to Figure 2 Preferably, the circulating ink supply system further includes a one-way valve 4 and a filter 5. The main ink cartridge, the ink supply pump, the one-way valve 4, the filter 5, and the transparent ink cartridge main body 1 are connected in sequence. Through the setting of the one-way valve 4, the ink in the transparent ink cartridge main body 1 is prevented from flowing back to the main ink cartridge. Through the setting of the filter 5, the ink can be filtered to remove impurities in the ink and improve the printing quality.

[0034] In summary, since the transparent ink cartridge main body 1 is made of transparent material, the user can directly observe whether the UV curing ink inside is bubbled, deposited, layered, and the remaining amount, etc. to avoid printing unqualified ink to the product and avoid ink breakage during printing, improve the product printing quality, and reduce material waste caused by abnormal ink. At the same time, through the setting of the ultraviolet-proof film, external ultraviolet radiation can be effectively blocked from the transparent ink cartridge main body 1 to avoid the UV curing ink inside the transparent ink cartridge main body 1 from being photocured to ensure that the UV curing ink can be stored for a long time. In addition, through the setting of the circulating component 3, a stable ink supply circulating loop can be formed between the transparent ink cartridge main body 1 and the nozzle 2 to improve the flowability of the ink, avoid the ink from being deposited and layered, and improve the printing quality.

[0035] The above merely provides an embodiment of the present application, but not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
