[0002] There are many types of printers, among which inkjet printers are a widely used type of printer. They have the advantages of high character dot resolution and high and clear printing quality.

[0003] In current industrial inkjet printer applications, the process requirements for the printhead are high due to the need to spray extremely small ink droplets for imaging. If the printhead is exposed to air for a long time, the ink will clog the nozzle holes of the printhead, thereby affecting the printing performance of the inkjet printer. In order to clean the printhead, a scraper is often used to scrape off the ink from the printhead.

[0004] However, when the scraper scrapes away the ink from the printhead, it is very likely to cause irreparable physical damage to the printhead, greatly reducing the service life of the printhead. In addition, the scraper is likely to leave a lot of ink after cleaning the printhead, and the scraper itself also needs regular cleaning and maintenance, which increases the process of printhead cleaning and maintenance, making the printhead maintenance efficiency low.

[0032] See Figure 1-Figure 3 The utility model provides a nozzle maintenance device, including a wiping assembly 1 and a moving assembly 2. The wiping assembly 1 includes a first roller 11, a second roller 12, a wiping cloth 13, a wiping drive 15 and a mounting seat 17. The wiping cloth 13 is wound around the first roller 11 and the second roller 12. The wiping drive 15 is transmission-connected to the first roller 11 or the second roller 12 so that the first roller 11 or the second roller 12 rotates and drives the wiping cloth 13 to move relative to the first roller 11 and the second roller 12. The first roller 11, the second roller 12 and the wiping drive 15 are all arranged on the mounting seat 17; the moving assembly 2 is connected to the mounting seat 17 for driving the mounting seat 17 to move along the first direction X.

[0033] In this embodiment, the length directions of the first roller 11 and the second roller 12 are parallel, and the lengths of the first roller 11 and the second roller 12 are equal. The first roller 11 and the second roller 12 are spaced apart along the first direction X and are respectively rotatably connected to the mounting seat 17. The first direction X is the arrangement direction of the nozzle (not shown in the figure), that is, the horizontal direction; the wiping cloth 13 is made of non-woven fabric material.

[0034] It should be noted that when maintaining the nozzle, the wiping cloth 13 is located under the nozzle and abuts against the nozzle, and the moving component 2 drives the mounting seat 17 to move so that the wiping cloth 13 wipes the nozzle to keep the nozzle clean. After the maintenance of the nozzle is completed, the moving component 2 drives the mounting seat 17 to reset, and rotates the first roller 11 or the second roller 12 so that the wiping cloth 13 stained with ink is wound onto the first roller 11 or the second roller 12, so that the wiping cloth 13 located between the first roller 11 and the second roller 12 remains clean.

[0035] In this way, the moving component 2 drives the mounting seat 17 to move along the first direction X, and makes the wiping cloth 13 located between the first roller 11 and the second roller 12 wipe the nozzle, which can remove ink and other dirt at the output end of the nozzle, and realize maintenance of the nozzle. Since the wiping cloth 13 is relatively soft, it is not easy to cause physical damage to the nozzle during the wiping process, thereby extending the service life of the nozzle; when the maintenance is completed, the wiping drive 15 drives the first roller 11 or the second roller 12 to rotate, and changes the relative position of the wiping cloth 13 and the first roller 11 and the second roller 12, and the ink-stained wiping cloth 13 can be wound around the first roller 11 or the second roller 12, so that each time the nozzle is maintained, the wiping cloth 13 located between the first roller 11 and the second roller 12 can be kept clean, avoiding the dirt on the wiping cloth 13 from clogging or scratching the nozzle, and can save the process of replacing the wiping cloth 13, thereby improving maintenance efficiency and ensuring the cleaning effect of the wiping cloth 13 nozzle.

[0036] It can be understood that the number of wiping components 1 can be flexibly adjusted according to the specifications and number of nozzles to be wiped. In this embodiment, two groups of wiping components 1 are provided, that is, two mounting seats 17 and two wiping cloths 13 are provided; the wiping cloth 13 can also be other soft materials that can absorb ink, which will not be listed in detail here.

[0037] See Figure 4 and Figure 5 In some embodiments, a mounting cavity 171 is provided inside the mounting seat 17 , and the wiping drive member 15 is located in the mounting cavity 171 and is transmission-connected to the second roller 12 to drive the second roller 12 to rotate, so that the wiping cloth 13 moves from the first roller 11 to the second roller 12 .

[0038] In this embodiment, a clean wiping cloth 13 is wound around the first roller 11, and the second roller 12 rotates and drives the wiping cloth 13 to move, so that the wiping cloth 13 output from the first roller 11 is wound around the second roller 12; one end of the second roller 12 is connected to the first gear 121, the wiping drive 15 is a motor, and the output end of the wiping drive 15 is fixedly connected to the second gear 151, and the mounting seat 17 is rotatably connected to the third gear 16 that is meshed with the first gear 121 and the second gear 151, so that the wiping drive 15 can rotate the second roller 12 through the third gear 16; the first roller 11 is rotatably connected to the mounting seat 17.

[0039] In this way, by driving the second roller 12 to rotate with the wiping drive 15, the wiping cloth 13 stained with ink can be gradually wound onto the second roller 12, and at the same time, the unwinding action of the wiping cloth 13 on the first roller 11 is realized, which facilitates the rapid adjustment of the wiping cloth 13, so that the nozzle can always be cleaned by the clean wiping cloth 13, saving the process of disassembling and replacing the wiping cloth 13 and improving maintenance efficiency.

[0040] See Figure 4 In some embodiments, the nozzle maintenance device further includes a first mounting member 3, to which one end of the first roller 11 and the second roller 12 on the same side is connected, for movably connecting the first roller 11 and the second roller 12 to the mounting seat 17. The first mounting member 3 is a spring pull bolt, and the end of the first roller 11 facing away from the first mounting member 3 and the end of the second roller 12 facing away from the first mounting member 3 are both rotatably connected to the mounting seat 17.

[0041] In this way, the spring pull bolt can limit the position of the first roller 11 and the second roller 12 on the mounting seat 17, so that the wiping cloth 13 can move stably on the first roller 11 and the second roller 12, and avoid the wiping cloth 13 falling off the first roller 11 or the second roller 12 due to the shaking of the first roller 11 or the second roller 12 on the mounting seat 17, affecting the cleaning and maintenance effect; by pulling the spring pull bolt, it is convenient for the staff to assemble the first roller 11 and the second roller 12 to the mounting seat 17, and when the clean wiping cloth 13 on the first roller 11 is used up, the first roller 11 and the second roller 12 can be replaced in time, saving replacement time and improving maintenance efficiency.

[0042] See Figure 2 and Figure 4 In some embodiments, the wiping assembly 1 further includes a support roller 14, which is disposed between the first roller 11 and the second roller 12. The support roller 14 protrudes from the first roller 11 and the second roller 12. When the nozzle is maintained, the distance between the first roller 11 and the nozzle and the distance between the second roller 12 and the nozzle are both greater than the distance between the support roller 14 and the nozzle, that is, the support roller 14 is higher than the first roller 11 and the second roller 12 and is disposed on the mounting seat 17, and the wiping cloth 13 is connected to the support roller 14.

[0043] In this embodiment, the distance between the first roller 11 and the bottom surface of the mounting seat 17 is equal to the distance between the second roller 12 and the bottom surface of the mounting seat 17, the two ends of the support roller 14 are rotatably connected to the mounting seat 17, and the length direction of the support roller 14 is parallel to the length direction of the mounting seat 17.

[0044] In this way, the support roller 14 can keep the wiping cloth 13 in contact with the nozzle and reduce the contact area between the wiping cloth 13 and the nozzle, thereby reducing the friction between the wiping cloth 13 and the nozzle, making it easier for the wiping cloth 13 to wipe the nozzle along the first direction X, thereby improving the cleaning and maintenance effect of the nozzle.

[0045] See Figure 4 In some embodiments, the nozzle maintenance device further includes a second mounting member 4, and a second mounting member 4 is connected to each end of a support roller 14, for movably connecting the support roller 14 to the mounting seat 17. In this embodiment, the second mounting member 4 is a spring pull bolt.

[0046] In this way, by setting up the second mounting member 4, it is convenient for the staff to assemble the support roller 14 to the mounting seat 17, thereby improving the replacement efficiency of the wiping cloth 13, making it easier to keep the wiping cloth 13 in contact with the nozzle clean, and avoiding the dirty wiping cloth 13 from clogging or scratching the nozzle.

[0047] It can be understood that the first mounting member 3 and the second mounting member 4 can also be structures such as fixed pins and top columns, and are not limited to spring pull bolts. They can limit the first roller 11, the second roller 12 and the support roller 14 and ensure that the first roller 11, the second roller 12 and the support roller 14 can rotate normally, which will not be elaborated here.

[0048] See Figure 3 and Figure 4 In some embodiments, the second mounting member 4 is slidably connected to the mounting base 17 along a second direction Y, which is perpendicular to the first direction X. In this embodiment, the second direction Y is a vertical direction, and the mounting base 17 is provided with a slot (not shown) for the second mounting member 4 to slide.

[0049] In this way, after the support roller 14 is assembled to the second mounting member 4, the second mounting member 4 is slid in the second direction Y, and the height of the support roller 14 on the mounting seat 17 can be adjusted, and then the highest position of the wiping cloth 13 can be flexibly adjusted according to actual needs, so that the wiping cloth 13 can always be in contact with the nozzle when moving along the first direction X, thereby improving the cleaning and maintenance effect of the nozzle and extending the service life of the nozzle.

[0050] It is understandable that the second mounting member 4 can also be a sleeve that is slidably connected to the mounting seat 17. The sleeve is slidably connected to the mounting seat 17. The connection method between the support roller 14 and the mounting seat 17 can be flexibly adjusted according to actual needs, and no further examples are given here.

[0051] See Figure 2 In some embodiments, the moving assembly 2 includes a moving seat 21, a transmission block 22 and a translation drive member 23. The mounting seat 17 is arranged on the moving seat 21. The moving seat 21 is detachably connected to the transmission block 22. The translation drive member 23 is transmission-connected to the transmission block 22 and is used to drive the transmission block 22 to drive the moving seat 21 and the mounting seat 17 to move along the first direction X.

[0052] Among them, the two mounting seats 17 are fixedly set on the moving seat 21, and the two mounting seats 17 are spaced apart along the third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y; the moving seat 21 and the transmission block 22 are detachably connected by bolts, and the moving assembly 2 also includes a guide rail 24, the transmission block 22 is set on the guide rail 24 and is slidably connected to the guide rail 24, the length direction of the guide rail 24 is parallel to the length direction of the transmission block 22, the translation drive 23 is a stepping motor, and the translation drive 23 is set at one end of the guide rail 24.

[0053] In this way, the translation drive member 23 drives the transmission block 22 and the movable seat 21 to move along the first direction X, so that the wiping cloth 13 cleans and maintains the nozzle, thereby improving the maintenance efficiency and cleaning effect. The movable seat 21 is detachably connected to the transmission block 22, which is convenient for loading and unloading the movable seat 21 to quickly replace or repair the wiping assembly 1.

[0054] It is understandable that using a stepper motor to make the transmission block 22 slide along the first direction X is an existing technology and will not be elaborated here; the translation drive member 23 can also be a linear drive member such as a linear motor or a cylinder, and the specific structure of the translation drive member 23 can be flexibly adjusted according to actual needs.

[0055] See Figure 2 In some embodiments, a baffle 211 is provided on one side edge of the movable seat 21 facing the mounting seat 17 , and the height of the baffle 211 is less than the height of the mounting seat 17 .

[0056] In this embodiment, the movable seat 21 includes an integrally formed vertical portion and a horizontal portion. One end of the vertical portion is connected to the transmission block 22, and the other end is connected to the horizontal portion. The horizontal portion is used to support the mounting seat 17, and the baffle 211 is set on the edge of the horizontal portion.

[0057] In this way, when the wiping cloth 13 wipes the nozzle along the first direction X, ink and other dirt may fall on the horizontal part. The baffle 211 can prevent the dirt from falling into the inside of the printer, thereby affecting the sanitary environment inside the printer. At the same time, the baffle 211 can enhance the structural strength of the movable seat 21, so as to stably support the mounting seat 17.

[0058] See Figure 1The utility model also provides an inkjet printer, including a body (not shown in the figure), a nozzle (not shown in the figure) and a nozzle maintenance device, wherein the nozzle and the nozzle maintenance device are both connected to the body.

[0059] The fuselage is connected to two maintenance plates 6 , which are arranged on both sides of the fuselage. Both ends of the guide rail 24 are detachably connected to the sides of the two maintenance plates 6 that are close to each other through bolts.

[0060] See Figure 1 and Figure 6 In some embodiments, the body is connected to a sensor 5 for sensing the movement of the printhead maintenance device in the first direction X. In this embodiment, the sensor 5 is a slot-type photoelectric switch sensor. The sensor 5 is communicatively connected to a control module, which is communicatively connected to the translation driver 23. The sensor 5 defines a sensing slot 51 and is disposed above the guide rail 24. A sensing plate 212 is connected to the top surface of the movable base 21. When the movable base 21 moves to the point where the sensing plate 212 is within the sensing slot 51 of the sensor 5, the sensor 5 controls the translation driver 23 to stop operating through the control module, thereby controlling the movement of the movable base 21.

[0061] Furthermore, the wiping drive 15 can also be connected to the control module for communication, so that when the sensing plate 212 slides to be located in the sensing slot 51, the sensor 5 sends a signal to the control module, so that the control module controls the wiping drive 15 to drive the second roller 12 to rotate, and the wiping cloth 13 that has wiped the nozzle is wound around the second roller 12, so that the next time the nozzle is maintained, the wiping cloth 13 located above the support roller 14 is clean.

[0062] In this way, by setting up the sensor 5, the maintenance efficiency can be improved, the labor cost can be saved, the wiping cloth 13 can stably clean the nozzle, and when the cleaning and maintenance work is completed, the clean wiping cloth 13 can be automatically moved above the support roller 14 to improve the maintenance effect.

[0063] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
