New description: [New technical field] The present invention relates to an inkjet device, in particular to a light absorbing member between the nozzle of the inkjet head and the opening of the bottom of the UV light projection device, which can be avoided. An ink jet device of a large ink jet printer that irradiates light to the nozzle of the ink jet head to harden the ink on the nozzle. [Prior Art] The printing method of the conventional printer is roughly classified into three types: inkjet type, thermal transfer type, and dot matrix type according to the type of the print head. Among them, the inkjet printer mainly has a base that can be controlled to move back and forth on the sliding platform of the machine, and a plurality of ink cartridges are arranged above the base, and a plurality of corresponding ones are arranged below the base. The ink jet head of each ink cartridge prints ink on the object through a nozzle at the bottom of the inkjet head, and then irradiates the UV light downward by a UV light projection device mounted on the side of the base to quickly solidify the ink to avoid When the pedestal moves back and forth, it touches the unsolidified ink, which affects the quality of the print. However, conventional inkjet printers flatten and bond the uv light projection device to the side of the pedestal such that the uv light 2 emitted by the uv light projection device is perpendicular to the surface of the printed object. When the uv light illuminates the object, scattering phenomenon is inevitably generated, and the nozzle of the ink jet head is irradiated, so that the ink on the nozzle is solidified, and the ink cannot be smoothly ejected, which is greatly affected by the printing effect. In order to avoid the above problems, the current practice is to separate the light emitting port of the light projecting device from the nozzle of the ink jet head, so that the volume of the ink jet printer will be increased, which is not in line with modern products. Chasing 5 M300172 for miniaturization. In view of this, in order to improve the above-mentioned social problems, the shortcomings of +Tianzhi's black dream Fanding find the heart & the large-scale inkjet printer mouth device is not only miniaturized in the month b, but also can be used on the second day. A + has blocked the nozzle of uv light to illuminate the inkjet head, so that the mouthpiece can be inkjet smooth, and the experience of the person who has accumulated many years of experience and continuous research and development improvement has produced this creation. [New content] The purpose is to provide a large (four) inkjet printer's inkjet device 'difficulty between the nozzle of the Hemo head and the opening of the bottom of the (4) light projection device - to avoid scattering The ϋν light is irradiated onto the nozzle of the ink jet head, causing the ink on the nozzle to harden, so that the nozzle can keep the ink jet smooth and prolong the service life. For the purpose of the above creation, an inkjet device of a large inkjet printer provided by the present invention comprises a base, an inkjet assembly and at least one light projection device. The inkjet assembly is fixed on the base. The inkjet assembly includes a plurality of inkjet heads for inkjet printing on the surface of the printed object; and the υν light projection device is fixed to the side of the base, the bottom of the light projection device is provided with an opening to The UV light is directed downward to illuminate the ink on the surface of the printed object to accelerate the solidification. The main technical feature of the present invention is that a light-dissipating member is disposed between the nozzle of the ink-jet head and the opening of the bottom of the ray-receiving device, thereby blocking the υν light from being irradiated to the nozzle of the ink-jet head, causing the ink on the nozzle to harden. The nozzle is blocked so that the nozzle can eject ink smoothly. In implementation, the UV light projection device includes a UV lamp mount and at least one xenon lamp hidden in the UV lamp mount. The light absorbing member includes a plurality of ribs provided with slopes. The light absorbing member can be disposed at the bottom of the pedestal, and the M300172 can be disposed at the bottom of the UV light projection device to achieve the same effect of blocking uv light. In addition, the creation may include a partition plate sandwiched between the side of the base and the UV lamp mount. When the bottom of the partition plate is provided with a light-blocking member, it can effectively avoid The UV light illuminates the nozzle of the ink jet head, causing the ink on the nozzle to harden to block the nozzle. In order to facilitate a deeper understanding of the creation, it is described in detail later: [Embodiment] 0 Please refer to Figures 1 and 2, which is the preferred inkjet device 1 for creating a large inkjet printer. The embodiment comprises a base 2, an ink jet assembly 3 and two UV light projection devices 4. The base 2 is a frame composed of a plurality of flat plates movably coupled to a sliding platform (not shown) of a large ink jet printer. The ink jet unit 3 includes a plurality of ink cartridges 31 fixed above the inside of the susceptor 2 and a plurality of ink jet heads 32 fixed under the susceptor 2, and the top end of the ink jet head 32 communicates with the ink cartridge 31 for input. The ink is provided, and the bottom end of the ink jet head 32 is provided with a nozzle for ejecting ink under control. When the susceptor 2 is moved back and forth on the sliding platform of the large ink jet printer, the ink can be printed on the surface of the object 9 to be printed. The two UV light projection devices 4 respectively include a liver lamp mount 41 and at least one UV lamp (not shown) hidden in the UV lamp mount 41. The two liver lamp fixing bases 41 are respectively fixed on two sides of the base 2, and the bottom of the uv lamp fixing bases 41 is provided with an opening 4Π for the uv light emitted by the uv lamp to illuminate the printed object downward. 9 surface ink, which accelerates the ink to solidify. Between the nozzle of the ink jet head 32 and the opening 4 of the UV light projecting device 4, a light absorbing member 5 is provided, and the light absorbing member 5 includes a plurality of ribs 52 which are parallel and provided with a slope 51. In the present embodiment, the light absorbing member 5 is bonded to the base, 2: the bottom portion ′, and in actual use, it can also be directly formed and formed at the bottom of the susceptor 2. As shown in Fig. 3, when the light emitted from the xenon lamp of the UV light projecting device 4 is directed to the surface of the object 9 to be printed, the light is generated by the plurality of inclined faces 51 provided by the light absorbing member 5. The action prevents the scattered (four) light from illuminating the nozzle of the ink jet head 32, causing the ink of the nozzle to harden, thereby blocking the nozzle. #Please refer to FIG. 4 , which is another embodiment of the light-shielding member 5 , wherein a partition plate 6 ′ is disposed between the side of the base 2 and the lamp holder 41. The 5 series is bonded to the bottom of the partitioning plate 6, and the light-blocking member 5 can also be directly formed at the bottom of the partitioning plate 6, and the effect of blocking UV light can also be achieved. Therefore, 'this creation has the following advantages: 1 This creation can effectively avoid the scattering of light by the light-blocking effect of a light-blocking member, and the light is irradiated to the nozzle of the ink-jet head, causing the ink on the nozzle to harden, not only enabling the nozzle It keeps the inkjet smooth and extends the life of the inkjet head. 2. The present invention does not increase the overall volume by placing a light absorbing member between the nozzle of the inkjet head and the opening of the bottom of the υν light projection device to block the scattered UV light. Therefore, it can meet the requirements of miniaturization. 3. This creation can be equipped with a light absorbing member at the bottom of the additional partition plate to be applied to the original inkjet device without 8 M300172 processing on the susceptor or uv light projection device. elasticity. In summary, according to the above disclosure, the creation is indeed possible: as expected (4), providing a nozzle that can not only be miniaturized, but also can block (four) illumination* inkjet head, so that the nozzle can be inkjet The inkjet device of the large-scale inkjet printer is very practical, and it proposes a new patent application according to law.
