Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a high-penetration digital printing inkjet head. Background Art

[0002] A printing machine is a type of printer. Its main function is to print corresponding patterns onto fabrics and other materials through corresponding materials. There are several types of printing machines. Digital printing machines are more advanced and easier to operate. Generally, the nozzles in digital printing machines are installed on the nozzle holder, and the nozzle holder and the nozzle are mostly fixed and connected by screws.

[0003] After the use of the printing machine inkjet head, the ink remaining on the nozzle is easy to dry and condense, resulting in the ink not being able to be sprayed out from the nozzle hole well when the nozzle is used for the second time. Because the nozzle connected by screws is troublesome to disassemble, the nozzle is usually cleaned directly on the printing machine using cleaning tools manually. However, during the cleaning, sewage will fall on the printing machine. After the nozzle is cleaned, the sewage on the printing machine needs to be cleaned again, which makes the cleaning of the nozzle very troublesome. Utility Model Content

[0045] Working principle: When installing the nozzle body 10, the staff pulls the control block 16 to the front side, and the control block 16 drives the sliding block 13 to start moving to the front side synchronously, and then the sliding block 13 moves away from the second connection port 11. At this time, the spring 14 begins to become compressed, and then the inside of the second connection port 11 is no longer blocked. Then, the nozzle body 10 is aligned with the second connection port 11 and then moved to the upper side. At the same time, the clamping block 20 is aligned with the connection groove 18, and then the nozzle body 10 will move to the inside of the ink storage tank 1 through the second connection port 11 and the first connection port 4. After the nozzle body 10 moves to the top of the limit groove 17, the nozzle body 10 is rotated, and then the nozzle body 10 drives the clamping block 20 to move. When the clamping block 20 is moved to the position of the clamping groove 19, and then the nozzle body 10 is released, the nozzle body 10 will move downward under the action of gravity, and then the nozzle body 10 drives the clamping block 20 to move to the inside of the clamping groove 19 to form a clamping connection, and then the installation of the nozzle body 10 can be completed. According to the above method, the disassembly of the nozzle body 10 can be completed. In this way, the nozzle body 10 and the nozzle seat 5 can be connected together without using screws, and then the disassembly and installation of the nozzle body 10 is relatively convenient. Therefore, when cleaning the nozzle body 10, it can be directly disassembled for cleaning, which avoids the printing machine from being dirty, thereby improving the cleaning convenience of the nozzle body 10.
