[0015] The utility model will be explained in detail in combination with the drawings and specific embodiments.

[0016] Please refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a nozzle cleaning device of drawing printer, including: machine table 1, set up in the nozzle moving module 2 of machine table 1, and set up on the movement end of nozzle moving module 2 printer nozzle 3, still including: the limit position of nozzle moving module 2 drive printer nozzle 3 movement is provided with cleaning box 4 in corresponding printer nozzle 3 of machine table 1, the sliding cleaning plate 5 of being slidably arranged on cleaning box 4, and the sponge of being arranged in cleaning box 4, the sliding cleaning plate 5 is provided with nozzle cleaning hole 51 in corresponding printer nozzle 3.

[0017] When the printing work is completed, or the set cleaning program is reached during the printing work, the printhead moving module 2 moves the printer printhead 3 to the corresponding position of the printhead cleaning device, and moves the printer printhead 3 downward, so that the nozzle of the printer printhead 3 extends into the printhead cleaning hole 51 of the sliding cleaning plate 5. At this time, the printer printhead 3 is driven by the printhead moving module 2 to move, so that the nozzle of the printer printhead 3 passing through the printhead cleaning hole 51 is in contact with the sponge and performs a wiping action on the sponge, so that the residual ink around the nozzle of the printer printhead 3 is absorbed and removed by the sponge, so that the nozzle is kept clean, and the residual ink is prevented from gathering into larger ink droplets and causing dirt on the drawing.

[0018] In some embodiments, a plurality of strip holes 41 are arranged on the front and rear walls of the cleaning box 4, respectively, and the strip holes 41 are arranged near the top of the cleaning box 4. The sliding cleaning plate 5 is provided with guide rods 52 corresponding to the strip holes 41, and the guide rods 52 are embedded in the strip holes 41 and move along the strip holes 41. The strip holes 41 on the front and rear sides cooperate with the guide rods 52 of the sliding cleaning plate 5 to provide guidance for the movement of the sliding cleaning plate 5, so as to prevent the sliding cleaning plate 5 from being deviated or warped during movement, thereby ensuring the cleaning effect of the printer printhead 3.

[0019] In some embodiments, one end of the strip hole 41 is inclined downward, and the other end of the strip hole 41 is arranged horizontally. When the printhead moving module 2 drives the printer printhead 3 to move, it will first move along the horizontal section of the strip hole 41 and wipe the nozzle of the printer printhead 3 with the sponge, and at this time the sponge will absorb the residual ink. When moving to the inclined section of the strip hole 41, under the cooperation of the guide rod 52 and the strip hole 41, the sliding cleaning plate 5 will move downward to press the sponge, so that the ink absorbed in the sponge is squeezed out, and at the same time the printer printhead 3 is separated from the sliding cleaning plate 5, and the cleaning work of the nozzle of the printer printhead 3 is completed. Since the upper part of the sponge is provided with the sliding cleaning plate 5, the squeezed-out ink will not stain the printer printhead 3, but will gather at the bottom of the cleaning box 4. When the printer printhead 3 leaves the cleaning area, the sliding cleaning plate 5 will be lifted upward under the elastic force of the sponge itself, and under the cooperative guidance of the strip hole 41 and the guide rod 52, the sliding cleaning plate 5 will be sent back to the initial position.

[0020] In some embodiments, the bottom of the cleaning box 4 is provided with a drainage hole 42. When ink is collected at the bottom of the cleaning box 4, the ink is discharged through the drainage hole 42 to avoid the situation that the sponge retains too much ink and pollutes the printer nozzle 3 in subsequent cleaning work. At the same time, during the movement of the sliding cleaning plate 5 downward along the strip hole 41, the ink absorbed by the sponge is squeezed out of the sponge due to the extrusion of the sliding cleaning plate 5 on the sponge, so that the ink is discharged out of the cleaning box 4 through the drainage hole 42.

[0021] In some embodiments, the bottom of the cleaning box 4 is provided with a liquid collecting bottle, and the drainage hole 42 is connected with the liquid collecting bottle 6 through a pipeline. When the ink flows out of the drainage hole 42, it is collected in the liquid collecting bottle 6. The ink is collected by the liquid collecting bottle 6, which facilitates the operator to collect and recycle the waste ink.

[0022] In some embodiments, the machine 3 is provided with a liquid pumping pump, the liquid inlet end of the liquid pumping pump is connected with the cleaning box 4 and contacts with the sponge, and the liquid outlet end of the liquid pumping pump is connected with the liquid collecting bottle 6. By starting the liquid pumping pump, the ink absorbed by the sponge is pumped through the liquid pumping pump, so that the ink is pumped into the liquid collecting bottle 6 for recycling, thereby avoiding the situation that the ink in the sponge pollutes the printer nozzle 3 again during cleaning, and improving the cleaning effect of the printer nozzle 3.

[0023] In summary, the printer nozzle is moved to the corresponding position of the nozzle cleaning device by the nozzle moving module, and the printer nozzle is moved downward, so that the nozzle of the printer nozzle extends into the nozzle cleaning hole of the sliding cleaning plate. At this time, the printer nozzle is driven to move by the nozzle moving module, so that the nozzle of the printer nozzle passing through the nozzle cleaning hole contacts the sponge and performs wiping action on the sponge, so that the residual ink around the nozzle of the printer nozzle is absorbed and removed by the sponge, so that the nozzle periphery is kept clean, and the situation that the residual ink is collected into larger ink droplets and pollutes the drawing is avoided.

[0024] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
