Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0049] The present utility model provides a cleaning and maintenance component for an inkjet head. The cleaning and maintenance component for the inkjet head includes: a bracket 1, a sliding plate 2, an ink pumping and moisturizing rack 3, a first driving element 4, and a second driving element 5. A rectangular hole 11 for printing is provided on the bracket 1; in actual use, the inkjet head is located above the rectangular hole 11, and the printing paper can pass through below the rectangular hole 11, and the inkjet head can print content on the printing paper when the printing paper passes through below the rectangular hole 11. The sliding plate 2 is slidably mounted on the bracket 1, and the sliding plate 2 is located within the rectangular hole 11. The first driving element 4 can push the sliding plate 2 to move in the direction of the X-axis within the rectangular hole 11, and the sliding plate 2 can drive the ink pumping and moisturizing rack 3 to move below the inkjet head in the printer. When the inkjet head in the printer is performing printing, the first driving element 4 drives the sliding plate 2 to move to the first station. At this time, the paper is directly below the inkjet head, and the inkjet head normally performs the inkjet printing work; when the inkjet head in the printer needs to be cleaned or moisturized, the first driving element 4 drives the sliding plate 2 to move to the second station. At this time, the ink pumping and moisturizing rack 3 on the sliding plate 2 is directly below the inkjet head. At this time, the ink absorbing plate 31 and the moisturizing plate 32 on the ink pumping and moisturizing rack 3 perform the cleaning and moisturizing work on the inkjet head to realize the automatic cleaning and moisturizing of the inkjet head.

[0050] An ink extraction and moisturizing holder 3 is provided with an ink absorption plate 31 and a moisturizing plate 32. The ink absorption plate 31 is provided with negative pressure holes 311. The ink absorption plate 31 can generate negative pressure at the negative pressure holes 311. The moisturizing plate 32 is provided with an annular sealing element 321 for abutting against the inkjet head. The ink extraction and moisturizing holder 3 is slidably mounted on the sliding plate 2. The second driving element 5 can push the ink extraction and moisturizing holder 3 to move along the direction where the Y-axis is located on the sliding plate 2. Both the ink absorption plate 31 and the moisturizing plate 32 can move to the lower part of the inkjet head.

[0051] Specifically, when the inkjet head in the printer needs to be cleaned, the first driving element 4 drives the sliding plate 2 to move to the second working position. Then the second driving element 5 drives the ink absorption plate 31 to move to the lower part of the inkjet head. The negative pressure holes 311 on the ink absorption plate 31 perform ink extraction on the outlet of the inkjet head, thereby sucking away the stains on the inkjet head and completing the cleaning work of the inkjet head. When the printer stops working, at this time the inkjet head needs to be moisturized. The first driving element 4 drives the sliding plate 2 to move to the second working position. The second driving element 5 drives the moisturizing plate 32 to move to the lower part of the inkjet orifice. At this time, the inkjet head abuts against the annular sealing element 321 on the moisturizing plate 32. The outlet of the inkjet head is located inside the annular sealing element 321, avoiding the outlet of the inkjet head being in contact with air for a long time, achieving the moisturizing effect on the inkjet head. Through the above analysis, it can be seen that in this application, a bracket 1 is provided below the inkjet head, and a rectangular hole 11 is provided on the bracket 1, so that the inkjet head can print on the paper through the rectangular hole 11. Then the sliding plate 2 is slidably arranged on the bracket 1. When the inkjet head needs to be cleaned and moisturized, the sliding plate 2 moves to the lower part of the inkjet head, and the ink extraction and moisturizing holder 3 is slid. The ink absorption plate 31 completes the negative pressure ink extraction on the inkjet head and then completes the cleaning work. The annular sealing element 321 on the moisturizing plate 32 abuts against the inkjet head, isolating the outlet of the inkjet head from the contact with air and achieving the moisturizing effect. The above cleaning and moisturizing of the inkjet head are completely automatic and do not affect the normal inkjet printing of the inkjet head.

[0052] Further, a plurality of ink absorption plates 31 and a plurality of moisturizing plates 32 are arranged in an array along the direction where the Y-axis is located on the ink extraction and moisturizing holder 3. A moisturizing plate 32 is arranged between any two adjacent ink absorption plates 31. During actual use, the inkjet heads in the printer are arranged in an array. One inkjet head corresponds to one ink absorption plate 31 and the first moisturizing plate 32. The ink absorption plates 31 and the moisturizing plates 32 are arranged in an interleaved manner. This enables when the function of the inkjet head needs to be switched (that is, when the inkjet head switches between the two functions of cleaning and moisturizing), only the second driving element 5 needs to drive the ink extraction and moisturizing holder 3 to reciprocate along the direction where the Y-axis is located, which is convenient for control.

[0053] Furthermore, the ink suction and moisture preservation rack 3 includes a cross beam 33, an ink suction mounting rack 34, and a moisture preservation mounting rack 35. The cross beam 33 is arranged on the sliding plate 2 along the direction where the Y axis is located. The ink suction mounting rack 34 and the moisture preservation mounting rack 35 are both arranged in an array on both sides of the cross beam 33. Specifically, a guiding groove is arranged on the bottom surface of the cross beam 33 (the bottom surface refers to the surface where the cross beam 33 abuts against the sliding plate 2), and a guiding protrusion is arranged on the sliding plate 2. The guiding protrusion is located in the guiding groove, and the guiding groove can play a guiding role in the movement of the cross beam 33 in the direction where the Y axis is located. In addition, in order to facilitate the cross beam 33 to drive the ink suction mounting rack 34 and the moisture preservation mounting rack 35 to move on the sliding plate 2, a butting strip is convexly arranged on the sliding plate 2 along the direction where the Y axis is located, and both the ink suction mounting rack 34 and the moisture preservation mounting rack 35 are in contact with the butting strip. Ink suction cavities 331 that communicate with each other are arranged on both the cross beam 33 and the ink suction mounting rack 34. The ink suction plate 31 is mounted on the ink suction mounting rack 34, and the ink suction cavity 331 is communicated with the negative pressure holes 311. The moisture preservation mounting rack 35 is used for mounting the moisture preservation plate 32.

[0054] In a preferred embodiment, a first spring 341 is arranged between the ink suction mounting rack 34 and the ink suction plate 31, and a second spring 351 is arranged between the moisture preservation mounting rack 35 and the moisture preservation plate 32. Both the first spring 341 and the second spring 351 can expand and contract in the direction where the Z axis is located. Limiting grooves 36 are arranged on both the ink suction mounting rack 34 and the moisture preservation mounting rack 35 along the direction where the Z axis is located, and limiting buckles 37 that are slidably mounted in the limiting grooves 36 are arranged on both the ink suction plate 31 and the moisture preservation plate 32. The limiting grooves 36 can limit the displacement of the limiting buckles 37 in the direction where the Z axis is located. Arranging the first spring 341 and the second spring 351 can enable the ink suction plate 31 and the moisture preservation plate 32 to be in close contact with the inkjet head, ensuring the effects of ink suction and moisture preservation. In addition, a guiding plate is also arranged on the bracket 1 in the present application, and the bracket 1 can move along the direction where the Z axis is located inside the printer.

[0055] In a preferred embodiment, a negative pressure groove 312 is arranged on the ink suction plate 31, and the negative pressure holes 311 are located at the bottom of the negative pressure groove 312. The negative pressure groove 312 can abut against the inkjet head and form a cavity, and the outlet of the inkjet head is located in the negative pressure groove 312. In the above solution, the negative pressure holes 311 are arranged at the bottom of the negative pressure groove 312, and the negative pressure groove 312 abuts against the inkjet head to form a cavity. The negative pressure holes 311 apply negative pressure to the entire cavity, avoiding the situation that the negative pressure holes 311 are directly aligned with the outlet of the inkjet head and sucking away the ink in the internal pipeline of the printer due to excessive negative pressure. A rubber scraping blade 313 is also arranged on the ink suction plate 31, and the rubber scraping blade 313 can contact the inkjet head. The rubber scraping blade 313 can scrape away the ink that has solidified on the inkjet head, improving the cleaning effect on the inkjet head.

[0056] In addition, an annular sealing element 321 and an ink discharging hole 322 are provided on one side of the moisture retaining plate 32 facing the inkjet head. The ink discharging hole 322 is surrounded by the annular sealing element 321. A guide ink column 323 is provided on the side of the moisture retaining plate 32 facing away from the inkjet head. A guide ink hole is provided on the guide ink column 323, and the guide ink hole is communicated with the ink discharging hole 322. An ink pool 352 is provided on the moisture retaining mounting bracket 35. The end of the guide ink column 323 is located in the ink pool 352. An ink flowing hole 353 is provided on the side wall of the ink pool 352. The ink in the ink pool 352 can flow from the ink flowing hole 353 to the sliding plate 2. In this application, the remaining amount of ink in the ink pool 352 can be controlled by controlling the position of the ink flowing hole 353, so that the ink can submerge the bottom end of the guide ink column 323, achieving a sealing effect, ensuring that when the annular sealing element 321 on the moisture retaining plate 32 abuts against the inkjet head, the inkjet head will not be in contact with the outside air, and improving the moisture retaining effect.

[0057] An ink groove 21 is recessed on the sliding plate 2. A waste ink collecting device 12 is provided on the bracket 1. The ink groove 21 is communicated with the waste ink collecting device 12. The waste ink flowing out of the ink pool 352 can flow into the ink groove 21 and finally flow into the waste ink collecting device 12 under the guiding action of the ink groove 21.

[0058] On the other hand, the first driving element 4 includes: a first driving motor 41, a worm 42, a pair of turbines 43, a pair of first push rods 44 and a pair of second push rods 45. The first driving motor 41, the worm 42 and the turbine 43 are all installed on the bracket 1. The first driving motor 41 is connected to the worm 42. The first driving motor 41 can drive the worm 42 to rotate. The turbine 43 meshes with the worm 42. The worm 42 is located between the two turbines 43, and the worm 42 can drive the two turbines 43 to rotate. One end of the first push rod 44 is fixedly connected to the turbine 43. The other end of the first push rod 44 is hinged to one end of the second push rod 45. The other end of the second push rod 45 is hinged to the sliding plate 2.

[0060] The driving frame 51 is connected to the ink pumping and moisturizing frame 3 through the connecting column 52. A connecting hole is provided on the connecting column 52, and the connecting hole can communicate with the negative pressure hole 311. A negative pressure pipe 511 communicating with the connecting hole is provided on the driving frame 51. Specifically, the connecting column 52 is fixedly connected to the cross beam 33, and when the connecting hole communicates with the ink suction cavity 331 on the cross beam 33, negative pressure can be applied at the negative pressure hole 311. The second driving motor 53 is fixedly installed on the bracket 1, the driving column 54 is rotatably installed on the bracket 1, the second driving motor 53 can drive the driving column 54 to rotate, teeth meshing with the rack 55 are provided on the circumferential surface of the driving column 54, the driving column 54 can drive the rack 55 to reciprocate, the rack 55 is fixedly connected to the driving frame 51, and the rack 55 drives the driving frame 51 to move, and then drives the ink pumping and moisturizing frame 3 to move in the direction of the Y axis through the connecting column 52.
