[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-7 , an embodiment provided by the present utility model:

[0025] A top-jet inkjet printing device includes a first connecting bracket 1. A lifting platform 2 is fixedly connected to the surface of the first connecting bracket 1 and can be lifted or lowered to the printing position and the moisture-preserving shutdown position with one key through an electric lifting structure. Above the first connecting bracket 1, there is a roller 3 for driving a conveying platform 4 to move. The surface of the roller 3 is provided with a conveying platform 4 for placing printing media. The surface of the first connecting bracket 1 is fixedly connected to a second connecting bracket 5 for connecting an ink cartridge assembly 6. The surface of the second connecting bracket 5 is movably connected to an ink cartridge assembly 6 for storing ink and performing electric heating. An installation hole 7 is opened on the surface of the ink cartridge assembly 6 for connecting a T-shaped screw 8. The surface of the ink cartridge assembly 6 is fixedly connected to a T-shaped screw 8, which can drive the ink cartridge assembly 6 to move. The surface of the ink cartridge assembly 6 is fixedly connected to an ink tube 9 for transmitting ink. The surface of the ink tube 9 is fixedly connected to a protective sleeve 10 for protecting a heating sheet 11. A heating sheet 11 is arranged inside the protective sleeve 10 for performing secondary heating. One end of the ink tube 9 far from the ink cartridge assembly 6 is fixedly connected to a nozzle assembly 12 for performing inkjet printing. The surface of the nozzle assembly 12 is provided with a printing nozzle 13 for performing inkjet printing.

[0026] Further, the lifting platforms 2 are symmetrically distributed in two groups on the surface of the first connecting bracket 1. The setting of the two groups improves the stability of the lifting of the first connecting bracket 1. The first connecting bracket 1 is movably connected to the surfaces of the lifting platform 2 and the conveying platform 4. The height of the lifting platform 2 is adjusted through a remote control or a control panel, and it can be lifted or lowered to the printing position and the moisture-preserving shutdown position with one key.

[0027] Further, the installation holes 7 are evenly opened on the surface of the ink cartridge assembly 6. The ink cartridge assembly 6 is movably connected to the surface of the second connecting bracket 5 through the T-shaped screw 8. Using the siphon principle, the ink cartridge assembly 6 is moved to adjust it to a proper position, so as to achieve no ink dripping and no ink leakage from the nozzles.

[0028] Further, both ends of the ink tube 9 are fixedly connected to the surfaces of the ink cartridge assembly 6 and the nozzle assembly 12. The ink cartridge assembly 6 is connected to the internal passage of the nozzle assembly 12 through the ink tube 9. After the ink in the ink cartridge assembly 6 is electrically heated, the ink is transported into the ink tube 9, and then is secondarily heated by the ink tube 9 and transported to the nozzle assembly 12 for use.

[0029] Further, the inside of the heating sheet 11 is hollow for placing the protective sleeve 10. Through grooves are opened on the surface of the heating sheet 11 for connecting the ink tube 9. The heating sheet 11 is fixedly connected to the surface of the ink tube 9 through the protective sleeve 10. The protective sleeve 10 acts on the surface of the ink tube 9 to secondarily heat the ink transported inside the ink tube 9, and then transports it into the nozzle assembly 12.

[0030] Further, the nozzle assembly 12 is movably connected to the surface of the first connection bracket 1. After the nozzle assembly 12 is installed, the spacing and horizontal position of each printing nozzle 13 can be determined according to the printing requirements of the customer, and then adjusted by moving.

[0031] Further, the printing nozzle 13 acts on the surface of the conveying platform 4 through the nozzle assembly 12 to perform inkjet printing on the printing medium to be inkjet. The printing nozzle 13 adopts a piezoelectric industrial nozzle, which improves the printing accuracy and clarity, and at the same time extends the service life of the equipment.

[0032] Working principle: When using the nozzle assembly 12, first fix the nozzle assembly 12 and the printing nozzle 13 together, and then install them on the first connection bracket 1. After installation, the height position remains unchanged, and the left and right positions of the nozzle assembly 12 can be adjusted. According to the width of the customer's conveying platform 4, confirm the total width of the installation bracket. According to the customer's printing requirements, determine the spacing and horizontal position of each nozzle. The ink cartridge assembly 6 is connected to the nozzle assembly 12 through an ink tube 9. The ink cartridge assembly 6 electrically heats the ink. The protective sleeve 10 and the heating sheet 11 perform secondary heating on the transmitted ink. Then, after the nozzle assembly 12 is installed and fixed, adjust the installation height of the ink cartridge assembly 6. Using the siphon principle, after the height of the ink cartridge assembly 6 is adjusted to a reasonable position, the ink of the printing nozzle 13 does not drip or leak. Install the T-shaped screw 8 on the first connection bracket 1, and then the position of the ink cartridge assembly 6 can be adjusted up and down through the installation hole 7. The lifting platform 2 is installed below the first connection bracket 1. Through the remote control or the control panel, adjust the height of the lifting platform 2. When the lifting platform 2 is adjusted, the positions of the ink cartridge assembly 6 and the nozzle assembly 12 can be raised and lowered simultaneously, which is convenient to change the distance between the printing nozzle 13 and the printing medium. Then, the printing medium can be placed at the conveying platform 4 for inkjet printing.
