[0002] Inkjet printers are widely used in the printing industry. Their working principle is that the ink pump sprays ink from the nozzle at a certain pressure to form a continuous ink flow. This ink flow gains static electricity in a high-voltage metal tube in the print head, becoming an orderly stream of ink droplets. Then, it is charged through a high-voltage electrical pipe. Once the charging signal is removed, the charged micro-ink droplets are deflected under the action of the DC electric field of the deflection electrode, forming the ink beam for printing, which is then shot onto the substrate to complete the printing process.

[0003] Existing inkjet printing printhead structures, after being used and left to stand for a period of time, are prone to clogging due to the high temperature generated by the machine body evaporating the water in the ink, resulting in the ink drying out. Therefore, an inkjet printing printhead structure is needed to help solve this problem. Utility Model Content

The cover assembly 6 includes a cover plate 7. An alcohol swab 71 is installed on the side of the cover plate 7 facing the printing inkjet head body 1. A cavity is opened inside the cover plate 7, and alcohol liquid 74 is installed inside the cavity. A liquid guide column 73 is installed inside the cavity, and the liquid guide column 73 is connected to one side of the alcohol swab 71. A sealing ring 72 is installed at the through hole of the cover plate 7 corresponding to the liquid guide column 73, and the liquid guide column 73 is installed through the sealing ring 72.

[0019] With the cover assembly 6 in place, the cover plate 7 can cover the inkjet nozzle 5 during operation. At this time, the alcohol cotton 71 is pressed against the top of the inkjet nozzle 5. The alcohol liquid 74 is guided into the alcohol cotton 71 through the capillary action of the liquid guide column 73, and the alcohol cotton 71 covers the inkjet nozzle 5. This achieves sealing and moisturizing treatment at the inkjet head, and avoids the problem that the high temperature generated by the machine body will evaporate the water in the ink, which can easily cause blockage and lead to the ink drying.

[0020] A liquid filling seat 9 is installed on one side of the cover plate 7. The liquid filling seat 9 is connected to the cavity. A fixing seat 10 is threaded onto the liquid filling seat 9. With the liquid filling seat 9, it is convenient to add liquid to the cavity after working for a period of time.

[0021] The inkjet head body 1 has an adsorption block 8 embedded on one side of the inkjet nozzle 5, and the cover plate 7 has an adsorption block 8 embedded on one side of the inkjet head body 1. The two adsorption blocks 8 work together to adsorb each other. Through the adsorption blocks 8, the cover plate 7 can play a role in adsorption and sealing at the top of the inkjet nozzle 5.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, a support rod 151 protrudes from one side of the cover plate 7, and an adjustment cavity is provided on one side of the inkjet head body 1. A transmission assembly 11 is installed in the adjustment cavity to drive the cover plate 7 to flip and cover. The transmission assembly 11 includes a lead screw 17 that is vertically rotatably installed in the adjustment cavity. A slider 12 is sleeved on the lead screw 17, and the slider 12 and the lead screw 17 are threaded together. An adjustment motor 18 that drives the lead screw 17 to rotate is installed at the bottom of the inkjet head body 1. A mounting base 13 is installed on the outer side of the slider 12, and a servo motor 16 is installed on the outer side of the mounting base 13. A first meshing gear 14 is installed at the front end of the shaft of the servo motor 16. A second meshing gear 15 is fixed at the end of the support rod 151 away from the cover plate 7.

When the first meshing gear 14 rotates, it meshes with the second meshing gear 15, causing the second meshing gear 15 to rotate as a whole. When the second meshing gear 15 rotates, it drives the support rod 151 to rotate 90 degrees. This allows the inkjet nozzle 5 to be easily covered or exposed during operation, minimizing problems such as the cover plate 7 failing to stably cover the inkjet head.

[0024] The slider 12 is provided with symmetrical limit grooves on both sides, and the limit strips 111 are symmetrically and vertically fixed in the adjustment cavity. The limit strips 111 are slidably arranged in the limit grooves. Through the cooperation between the limit grooves and the limit strips 111, the slider 12 can be easily and stably slidably arranged in the adjustment cavity during operation.

[0025] Working principle: During operation, the inkjet head body 1 is installed in the corresponding position with the inkjet nozzle 5 facing downwards. When the cover plate 7 is needed to cover the inkjet head body 1, the adjusting motor 18 is started. The adjusting motor 18 drives the lead screw 17 to rotate forward. The slider 12 is threadedly engaged with the lead screw 17, causing the slider 12 to move. The servo motor 16 is started, driving the first meshing gear 14 to rotate. When the first meshing gear 14 rotates, it meshes with the second meshing gear 15, causing the second meshing gear 15 to rotate. When the second meshing gear 15 rotates, it drives the support rod 151 to rotate 90 degrees. At this time, the adjusting motor 18 is started, driving the lead screw 17 to rotate in reverse, so that the cover plate 7 covers the inkjet nozzle 5. At this time, the alcohol cotton swab 71 is pressed on the top of the inkjet nozzle 5, thereby achieving sealing and moisturizing treatment.
