Both ends of the movable cover 4 are fixedly connected to connecting rods 41. The movable cover 4 is rotatably connected between the two support frames 2 through the connecting rods 41. The movable cover 4 is semi-circular. By driving the movable cover 4 to rotate around the connecting rods 41, the two movable covers 4 are flipped and closed, covering the printing head body 3 inside the two movable covers 4. An electric heating tube 5 and a brush 6 are fixedly connected to the inner wall of the movable cover 4. By activating the electric heating tube 5, the nozzles on the outer surface of the printing head body 3 are heated. During the rotation of the printing head body 3, the outer surface of the printing head body 3 is cleaned by the brush 6. A lifting frame 7 is slidably connected to the top of the two support frames 2. An electric push rod 72 is fixedly connected to the support frame 2. The telescopic end of the electric push rod 72 is fixedly connected to the lifting frame 7. A sliding groove is opened on the top of the support frame 2. The bottom of the lifting frame 7 slides inside the sliding groove. By activating the electric push rod 72, the lifting frame 7 is driven to adjust the height of the top of the support frame 2.

[0024] Please refer to it again. Figure 1 and Figure 2 The lifting frame 7 is equipped with a drive mechanism that drives two movable covers 4 to flip and close. The drive mechanism includes a connecting rod 71 hinged to the lifting frame 7. The other end of the connecting rod 71 is hinged to the movable cover 4 through a pin. When the lifting frame 7 descends or rises, the connecting rod 71 drives the two movable covers 4 to rotate, causing them to close or open. When the two movable covers 4 are closed, there is a gap between the ends of the two movable covers 4 that are equipped with connecting rods 41.

[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 4 The lifting frame 7 is equipped with a striking mechanism that repeatedly strikes the printing head body 3. The striking mechanism includes a striking rod 8 that slides on the lifting frame 7. A top plate 81 is fixedly connected to the top of the striking rod 8. A spring 82 is sleeved on the striking rod 8. By squeezing the top of the top plate 81, one end of the striking rod 8 is pushed through the gap between the two movable covers 4 to strike the outer surface of the printing head body 3. Then, the rebound of the spring 82 drives the striking rod 8 to rise and slide rapidly.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 4A rotating rod 9 is rotatably connected to the top of the lifting frame 7. A cam 91 is fixedly connected to the rotating rod 9.

[0027] Working principle: When the printhead body 3 needs to be cleaned, the electric push rod 72 is activated to drive the lifting frame 7 to descend. Under the connection of the connecting rod 71, the two movable covers 4 are driven to flip and close. The electric heating tube 5 is activated to heat the outer surface of the printhead body 3. The ink trapped inside the nozzle becomes drier due to the heat, and the volume of the dried ink decreases, thus creating a larger gap with the inside of the nozzle. The second motor 92 is activated to drive the rotating rod 9 to rotate. The protruding end of the cam 91 presses the top of the top plate 81. Then, the spring 82 rebounds and drives the striking rod 8 to rise. The striking rod 8 repeatedly strikes the outer surface of the printhead body 3 to shake off the ink inside the nozzle. The first motor 31 is activated to drive the printhead body 3 to rotate between the two movable covers 4. The brush 6 further cleans the outer surface of the printhead body 3.
