[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The present invention proposes an ink stack device 1 for an inkjet printer 100. The inkjet printer 100 includes a printing table 3 and a print head 2. The printing table 3 can be used to carry printing materials. The print head 2 reciprocates on the printing table 3 to print patterns on the printing materials. The ink stack device 1 is used to clean and / or moisturize the nozzle 21 of the print head 2, which helps to avoid ink condensation at the nozzle 21 and clogging the nozzle. When the print head 2 performs a printing job for a certain period of time or finishes the job and is on standby, the print head 2 can be adjusted to a trimming state so that the print head 2 moves to the top of the ink stack device 1 for cleaning or docking, so that the print head 2 can better perform subsequent printing jobs, further improving the practicality and reliability of the inkjet printer 100.

[0046] See also Figures 1 to 3 In order to facilitate the ink stack device 1 to clean the nozzle 21 of the print head, the ink stack device 1 is optionally provided on the movement path of the print head 2. In one embodiment, the print head 2 slides back and forth along the first direction X on the printing table 3, and the ink stack device 1 is correspondingly provided on one side of the printing table 3 along the first direction X, that is, the ink stack device 1 is located on the left or right side of the printing table 200, so as to facilitate the movement of the print head 2 between the ink stack device 1 and the printing table 3, reduce the movement path from the print head 2 to the ink stack device 1, and realize a more compact structural design of the inkjet printer 100. Of course, in other embodiments, the ink stack device 2 and the printing table 3 can also be arranged in other ways, which is not limited by this solution, as long as the ink stack device 1 can clean the print head 2.

[0047] The inkjet printer 100 may be a thermal inkjet printer, a piezoelectric inkjet printer, or a white ink heat transfer printer, such as a DTF printer ("Direct to Film," a printer that prints directly onto film) or a white ink direct-to-garment printer (DTG printer). Any device capable of jetting ink for printing may be used. The printing material used by the inkjet printer 100 in this application may be paper, film, or, of course, fabric. This application does not limit the material or shape of the printing material; any material that can be printed in the inkjet printer 100 is sufficient.

[0048] See also Figure 4 、 Figure 5 and Figure 11 In one embodiment of the present invention, the ink stack device 1 includes an ink stack platform 11 , a cleaning member 116 and a cover plate 12 .

[0049] The ink stack platform 11 is provided with a sewage collecting tank 111;

[0050] A cleaning member 116 is provided in the dirt collecting tank 111 and is used to clean the print head 2;

[0051] The cover plate 12 covers the notch of the sewage collecting tank 111 and is provided with a relief portion 125 . The cleaning member 116 at least partially extends out of the relief portion 125 , and a flow gap 121 is defined between the relief portion 125 and the cleaning member 116 .

[0052] In the related art, the ink stack device 1 is capable of cleaning the print head 2 of the inkjet printer 100, mainly involving the cleaning of the nozzles 21 on the print head 2. Therefore, a sewage collecting tank 111 is provided on the ink stack platform 11, and a cleaning member 116 is provided in the sewage collecting tank 111. The cleaning member 116 cleans the nozzle 21, and the sewage generated during the cleaning process flows into the sewage collecting tank 111. However, in the related art, the sewage collecting tank 111 is often open, that is, there is no cover plate 12 or other structure at its slot. Therefore, the sewage in the sewage collecting tank 111 may splash out during use, transportation and handling, which will not only pollute the interior of the inkjet printer 100, but may also cause damage to the electronic components of the inkjet printer 100, increasing maintenance costs and the risk of equipment failure.

[0053] Therefore, a cover plate 12 is provided. This cover plate 12 covers the notch of the sump 111, thereby sealing the sump 111 as a whole. This reduces wastewater splashing and prevents dirt or wastewater within the sump 111 from being exposed and affecting the aesthetics of the inkjet printer 100. Furthermore, the cover plate 12 is provided with a relief portion 125 through which the cleaning member 116 passes. The cleaning member 116 at least partially extends out of the relief portion 125 to facilitate cleaning of the print head 2. A flow gap 121 is defined between the relief portion 125 and the cleaning member 116, allowing dirt or wastewater cleaned by the cleaning member 116 to flow steadily through the relief gap 121 into the sump 111, thereby reducing the accumulation of dirt or wastewater on the cover plate 12. Compared to providing a flow hole connecting to the sump 111 at other locations on the cover plate 12, this solution helps reduce the flow path of wastewater into the sump 111, thereby facilitating the flow of wastewater or dirt into the sump 111.

[0054] The cover plate 12 is detachably mounted on the ink stack platform 11 or movably mounted on the ink stack platform 11 so that the cover plate 12 can cover or open the slot of the dirt collecting tank 111. In other embodiments, the cover plate 12 can also be fixed to the slot.

[0055] In this embodiment, refer to Figure 5 and Figure 11 The cover plate 12 has a recess 124 on a portion thereof, which can be inserted into the notch of the sump 111, and an escape portion 124 is formed in the recess 124. Specifically, the escape portion 125 is correspondingly provided in the recess 124, thereby increasing the extension length of the cleaning member 116 from the recess 124, making it easier for the cleaning member 116 to clean the nozzle 21. In addition, if the sewage generated during the cleaning process cannot flow into the sump 111 in a timely manner, the presence of the recess 124 can temporarily store the sewage, thereby effectively reducing the outflow of sewage. Moreover, the recess 124 inserted into the notch of the sump 111 can also effectively reduce the possibility of the cover plate 12 shifting or shaking relative to the ink stack platform 11. The recess 124 can be formed by local stamping of the cover plate 12, thereby facilitating the processing of the cover plate 12.

[0056] Among them, there are many ways for the cleaning member 116 to clean the nozzle 21. For example, the condensed ink on the nozzle 21 can be removed by scraping, or the nozzle 21 can be cleaned with a detergent. Of course, it can also be a combination of multiple cleaning methods, such as scraping first and then cleaning, etc. This application does not limit the cleaning method of the cleaning member 116, and it is sufficient that the cleaning member 116 can clean the nozzle 21.

[0057] The cross-sectional shape of the ink stack platform 11 can be a regular shape, such as a square or a circle, or an irregular shape, which is not limited in this application. The shape of the sewage collecting tank 111 can be a regular shape, such as a square or a circle, or an irregular shape.

[0058] In one embodiment, reference Figure 1 and Figure 2 The inner circumference of the avoidance portion 125 and the outer circumference of the cleaning member 116 are separated to form a flow gap 121. That is, the size of the avoidance portion 125 is slightly larger than the size of the cleaning member 116, so that the inner circumference of the avoidance portion 125 and the outer circumference of the cleaning member 116 form a gap, thereby forming the flow gap 121. This structure can be achieved by simply increasing the size of the avoidance portion 125, thereby facilitating the processing of the cover plate 12.

[0059] In another embodiment, the inner circumference of the avoidance portion 125 and / or the outer circumference of the cleaning member 116 is provided with a flow groove, and the flow groove forms a flow gap 121, that is, the inner circumference of the avoidance portion 125 and / or the outer circumference of the cleaning member 116 is partially recessed to form a flow groove. The avoidance portion 125 and the cleaning member 116 are assembled together to form a flow opening therebetween that connects to the sewage collection tank 111, thereby expanding the local gap between the avoidance portion 125 and the cleaning member 116, and facilitating the flow of sewage or dirt into the sewage collection tank 111. The flow groove may be provided only on the inner circumference of the avoidance portion 125, or only on the outer circumference of the cleaning member 116, or on both the inner circumference of the avoidance portion 125 and the outer circumference of the cleaning member 116; and the number of the flow grooves may be one or more, and the multiple flow grooves are arranged in sequence along the inner circumference of the avoidance portion 125 and / or the outer circumference of the cleaning member 116.

[0060] See also Figure 4 、 Figures 6 to 9 In an embodiment of the present invention, the cleaning member 116 includes a scraper 112, and the avoidance portion 125 includes a first avoidance hole 122. The scraper 112 at least partially extends out of the first avoidance hole 122. That is, in this embodiment, ink condensed on the nozzle 21 is removed by at least scraping. The first avoidance hole 122 is provided on the corresponding cover plate 12, and the scraper 112 extends out of the first avoidance hole 122, thereby cleaning the condensed ink on the nozzle 21. A flow gap 121 is formed between the scraper 112 and the first avoidance hole 122, allowing the removed ink to flow into the sump 111 through the flow gap 121, thereby preventing the possibility of ink accumulation on the cover plate 12.

[0061] The scraper 112 can be made of materials such as silicone and rubber to provide a certain degree of softness to prevent the scraper 112 from scratching the nozzle 21. Of course, the scraper 112 can also be made of other materials. This application does not limit the shape and material of the scraper 112, as long as it can clean the nozzle 21. In other embodiments, the scraper 112 can also be a brush or the like.

[0062] To facilitate the installation of the scraper 112, in one embodiment, the ink stack platform 11 further includes a scraper holder 113 provided on the dirt collecting tank 111, and the scraper 112 is detachably mounted on the scraper holder 113. Specifically, the scraper 112 is detachably mounted on the scraper holder 113, which can be conducive to better maintenance or replacement of the scraper 112, and prevent the scraper 112 from being damaged and affecting the cleaning effect of the ink stack device 1 on the nozzle 21, thereby further improving the practicality of the inkjet printer 100. The scraper 112 can be installed on the scraper holder 113 by means of plug-in connection, or the scraper holder 113 and the scraper 112 can be fastened to each other by bolts. There are many ways to connect the scraper holder 113 and the scraper 112, which is not limited in this application. It is sufficient to achieve a stable connection and convenient disassembly and assembly between the scraper 112 and the scraper holder 113.

[0063] In this embodiment, a slot 1131 is provided on the scraper seat 113, and the scraper 112 includes a scraper portion 1123 and a plug-in portion 1121, and the plug-in portion 1121 is plugged into the slot 1131. That is, the scraper 112 is installed on the scraper seat 113 by a plug-in method. Figure 10 The scraper 112 includes a scraper portion 1123 and a plug-in portion 1121 located on the side of the scraper portion 1123 facing the dirt collecting tank 111. The scraper 112 can be detachably installed by plugging the plug-in portion 1121 into the slot 1131. Optionally, the size of the plug-in portion 1121 is smaller than that of the scraper portion 1123, so that a limiting step 1124 is formed at the connection between the plug-in portion 1121 and the scraper portion 1123. On the one hand, it is a plug-in limit, and on the other hand, the limiting step 1124 can cover the slot 1131, thereby reducing the possibility of ink falling into the slot 1131. Further, optionally, see Figure 7 、 Figure 9 and Figure 10 The side wall of the slot 1131 is provided with an adjustment notch 1134 extending along the depth of the slot 1131. The existence of the adjustment notch 1134, on the one hand, improves the elasticity of the slot 1131 and facilitates the insertion of the plug-in part 1121; on the other hand, it also facilitates the cleaning of the slot 1131 and reduces the possibility that the ink accidentally falls into the slot 1131 and cannot be discharged.

[0064] The scraper seat 113 can be integrally formed in the dirt collecting tank 111, thereby facilitating the assembly of the ink stack device 1 and ensuring the installation strength of the scraper 112. Of course, in other embodiments, the scraper seat 113 can also be bonded or clamped to the inner wall of the dirt collecting tank 111.

[0065] In one embodiment, the scraper seat 113 extends out of the first avoidance hole 122 and forms a flow gap 121 between the scraper 112 and the wall of the first avoidance hole 122. That is, the scraper seat 113 is further positioned between the scraper 112 and the wall of the first avoidance hole 122, and the flow gap 121 is indirectly formed between the scraper 112 and the wall of the first avoidance hole 122.

[0066] In another embodiment, the scraper seat 113 does not extend out of the first avoidance hole 122 , and a flow gap 121 is formed between the scraper 112 and the hole wall of the first avoidance hole 122 .

[0067] In one embodiment, the plug-in portion 1121 and the slot 1131 are interference fit, which not only facilitates the insertion of the plug-in portion 1121 into the slot 1131 , but also ensures the stable installation of the scraper 112 and facilitates the installation of the plug-in portion 1121 and the slot 1131 .

[0068] Reference Figure 7 、 Figure 9 and Figure 10 In another embodiment, a latching protrusion 1122 is provided on one side of the plug-in portion 1121, and a latching hole 1132 is provided on the wall of the slot 1131. The latching protrusion 1122 can be latched into the latching hole 1132. When the plug-in portion 1121 is fully inserted into the slot 1131, the latching protrusion 1122 can be latched into the latching hole 1132, thereby effectively reducing the possibility of the plug-in portion 1121 accidentally falling out of the slot 1131 and facilitating the latching connection between the plug-in portion 1121 and the slot 1131.

[0069] Optionally, the sidewalls of the slot 1131 are provided with anti-slip ribs 1133, which can abut against the plug-in portion 1121. The anti-slip ribs 1133 protrude from the slot 1131. When the plug-in portion 1121 is inserted into the slot 1131, the anti-slip ribs 1133 can abut against the plug-in portion 1121 on the other side of the slot 1131, thereby effectively reducing the possibility of the plug-in portion 1121 falling out of the slot 1131. Furthermore, optionally, the retaining hole 1132 and the anti-slip ribs 1133 are provided on opposite sides of the slot 1131. To facilitate insertion of the plug-in portion 1121, a guide surface 1135 is provided on one end of the anti-slip rib 1133, which faces the notch of the slot 1131.

[0070] Please refer to Figures 1 to 11In an embodiment of the present invention, the cleaning member 116 further includes an ink pad 114, which is disposed on one side of the scraper 112 and is used to at least moisturize the nozzles 21 of the print head 2. The relief portion 125 further includes a second relief hole 123, through which the ink pad 114 at least partially extends. Specifically, when the print head 2 is placed on the ink stack device 1 for cleaning, the nozzles 21 can come into contact with the ink pad 114. The ink pad 114 at least moisturizes the nozzles 21 of the print head 2 and often also has a certain cleaning effect. The ink pad 114 is arranged in the dirt collecting tank 111 of the ink stack platform 11, and a second avoidance hole 123 is provided on the cover plate 12. The ink pad 114 at least partially extends out of the second avoidance hole 123, so that the dirt or sewage generated when the ink pad 114 cleans the nozzle 21 flows into the dirt collecting tank 111 through the flow gap 121 between the second avoidance hole 123 and the ink pad 114, thereby preventing dirt or sewage from splashing in the inkjet printer 100.

[0071] In one embodiment, the ink pad 114 includes an ink pad base 1143 and a gasket disposed above the ink pad base 1143. The ink pad base 1143 is fixed within the sump 111 to mount the ink pad 114 within the sump 111. A piping structure is provided within the ink pad base 1143 to provide liquid (such as water or cleaning fluid) to moisten the gasket and to drain waste liquid from the ink pad 114. The gasket may have a certain function of absorbing and condensing ink, or may have a certain function of wiping condensed ink. The present application does not limit the type of gasket, as long as it can achieve the functions of moisturizing and cleaning the nozzle 21. The gasket may include a sponge, absorbent cotton, etc.

[0072] In order to facilitate the installation of the ink pad 114 in the dirt collecting tank 111, in one embodiment, referring to Figure 8 The bottom of the ink pad base 1143 is provided with a laterally protruding mounting protrusion 1141 on one side. A mounting hole 1142 is provided corresponding to this mounting protrusion 1141. A fastener passes through mounting hole 1142 and secures it to the bottom of the sump 111, thereby pressing and securing the ink pad 114 within the sump 111. Furthermore, the sump 111 has a through-hole at the bottom of the ink pad 114. This allows a water inlet pipe to pass through this through-hole and connect to the piping structure within the ink pad base 1143, thereby supplying cleaning fluid to the gasket. To ensure a seal between the ink pad 114 and the through-hole, a sealing ring can be provided at the bottom edge of the ink pad base 1143. This seal is ensured by the ink pad 114 pressing against the bottom of the sump 111.

[0073] Please refer to Figure 1 and Figure 2When the ink stack device 1 is placed on one side of the printing table 3 along the first direction, optionally, the scraper 112 and the ink pad 114 are arranged along the first direction, and the scraper 112 is arranged closer to the printing table 3 than the ink pad 114, so that the print head 2 first contacts the scraper 112 and then contacts the ink pad 114 during the process of moving from the printing table 3 to the ink stack device 1, so that the condensed ink on the nozzle 21 can be better scraped off under the action of the scraper 112, and then the nozzle 21 can be kept in a good state for printing after being cleaned and moisturized by the ink pad 114, and the movement path of the print head 2 during cleaning can also be reduced.

[0074] In this embodiment, the inkjet printer 100 can be a white ink heat transfer printer. The ink used is typically composed of four colors (CMYK) ("Cyan Magenta Yellow blacK," four-color printing) and white. Accordingly, the print head 2 is equipped with two nozzles 21: one nozzle 21 is a color ink nozzle 21 for color ink printing corresponding to the four CMYK colors; the other nozzle 21 is a white ink nozzle 21 for white ink printing. During use, the print head 2 can first print a color pattern or text on the printing material using one nozzle 21, and then use the other nozzle 21 to print a layer of white ink over the color pattern. In this way, the white ink printing on the printing material can make the printed color pattern or text more vivid.

[0075] The two nozzles 21 are arranged at intervals. For example, when the print head 2 reciprocates in a first direction, the two nozzles 21 are arranged side by side in a second direction. Two ink pads 114 and two scrapers 112 are correspondingly provided in the dirt collection tank 111. The two ink pads 11 are arranged side by side in the second direction, and the two scrapers 112 are also arranged side by side in the second direction to clean and maintain the two nozzles 21. In other embodiments, the number of nozzles 21 may be one or more than three, and preferably the number of ink pads 114 and scrapers 112 is the same.

[0076] See also Figure 11 and Figure 12In an embodiment of the present invention, the ink stack device 1 further includes a support base 131 and a lifting mechanism 13. The ink stack platform 11 is mounted on the support base 131, and the lifting mechanism 13 is mounted on the support base 131 and is transmission-connected to the ink stack platform 11 to drive the ink stack platform 11 to rise and fall. Specifically, the support base 131 serves as the main supporting structure of the ink stack device 1 and is installed within the inkjet printer 100. It is used to provide for the installation of the ink stack platform 11 and the lifting mechanism 13. The lifting mechanism 13 is transmission-connected to the ink stack platform 11 so that the ink stack platform 11 can have a clean state close to the printing table 3, and a evasive state away from the printing table 3. It is understandable that when the print head 2 needs to be cleaned, the lifting mechanism 13 can be controlled to drive the ink stack platform 11 to rise so that the ink pad 114 contacts the nozzle 21 for cleaning; and when the print head 2 needs to leave the nozzle 21, the lifting mechanism 13 can be controlled to drive the ink stack platform 11 to fall so that the ink stack platform 11 is away from the print head 2 to avoid the movement of the print head 2, which is conducive to better realizing the automatic control of the ink stack device 1. Among them, the lifting mechanism 13 drives the ink stack platform 11 to move up and down. Compared with driving the ink stack platform 11 to move horizontally, this solution can reduce the movement space required by the ink stack platform 11 and contribute to the miniaturization of the equipment. Of course, in other embodiments, other driving mechanisms can also be provided, which can drive the ink stack platform 11 to move horizontally to avoid the print head 2. This application does not limit the transmission method of the lifting mechanism 13, and it is sufficient to be able to realize the switching of the ink stack platform 11 between the cleaning state and the avoidance state.

[0077] Furthermore, the lifting mechanism 13 includes a motor 132 and a transmission rod 133 provided on a support seat 131. The support seat 131 includes a side plate 134. The transmission rod 133 is movably mounted on the side plate 134. One end of the transmission rod 133 is transmission-connected to the motor 132, and the other end is transmission-connected to the ink stack platform 11. The motor 132 is provided on the support seat and is used to drive the transmission rod 133 to move relative to the side plate 134 to drive the ink stack platform 11 to rise and fall.

[0078] Specifically, the support base 131 includes a bottom plate 137 disposed substantially parallel to the ink stack platform 11, and side plates 134 disposed on the sides of the bottom plate 137, so that the support base 131 is arranged as a box. The ink stack platform 11 is disposed opposite the bottom plate 137 and can be raised and lowered away from or closer to the bottom plate 137. The side plates 134 are correspondingly enclosed on all sides of the ink stack platform 11. Therefore, the side plates 134 are disposed at an angle to the ink stack platform 11 and are parallel to the lifting direction of the ink stack platform 11, thereby improving the movement reliability of the ink stack platform 11. The transmission rod 133 is movably mounted on the side plates 134, so that the side plates 134 provide support for the movement of the transmission rod 133. One end of the transmission rod 133 is transmission-connected to the motor 132, and the other end is transmission-connected to the ink stack platform 11. The motor 132 drives one end of the transmission rod 133 to swing, thereby causing the other end of the transmission rod 133 to swing, thereby achieving the lifting and lowering of the ink stack platform 11.

[0079] The motor 132 can be fixed to the bottom plate 137 or to the side plate 134, thereby ensuring the stable installation of the motor 132 and stably driving the movement of the transmission rod 133. In this embodiment, the motor 132 is arranged on the outside of the support base 131, thereby reducing the internal space occupied by the motor 132 on the support base 131 and facilitating the arrangement of other structures of the lifting mechanism 13. Of course, in other embodiments, the motor 132 can also be arranged on the inside of the support base 131. In this solution, there are often multiple transmission rods 133, and the multiple transmission rods 133 are at least arranged on opposite sides of the ink stack platform 11, thereby ensuring the lifting stability of the ink stack platform 11 and ensuring the stability of the cleaning surface 117 of the ink stack platform 11.

[0080] In other embodiments, the lifting mechanism 13 may also include a motor 132, a first rocker arm and a second rocker arm arranged alternately, the middle parts of the first rocker arm and the second rocker arm are rotatably connected to each other, and one end of the first rocker arm and the second rocker arm are both rotatably connected to the ink stack platform 11, and at least one of the other ends of the first rocker arm and the second rocker arm is connected to the motor 132 along the transmission, and the motor 132 drives the first rocker arm and / or the second rocker arm to move, thereby changing the angle between the first rocker arm and the second rocker arm, thereby realizing the lifting and lowering of the ink stack platform 11.

[0081] Furthermore, a first guide limit groove 1341 and a second guide limit groove 1342 are formed on the side plate 134, and the second guide limit groove 1342 extends along the lifting direction of the ink stack platform 11. One end of the transmission rod 133 is movably mounted in the first guide limit groove 1341 and is transmission-connected to the motor 132. The other end of the transmission rod 133 is movably mounted in the second guide limit groove 1342 and is connected to the ink stack platform 11.

[0082] The motor 132 is used to drive one end of the transmission rod 133 to slide in the first guide limiting groove 1341 , so as to drive the other end of the transmission rod 133 to slide in the second guide limiting groove 1342 .

[0083] Specifically, the second guide limit groove 1342 extends along the lifting direction of the ink stack platform 11, and the first guide limit groove 1341 and the second guide limit groove 1342 are set at an angle. Optionally, the first guide limit groove 1341 is parallel to the ink stack platform 11, that is, the first guide limit groove 1341 extends in the horizontal direction, and the second guide limit groove 1342 extends in the vertical direction, and one end of the transmission rod 133 is movably installed in the first guide limit groove 1341 and is connected to the motor 132 for transmission, so as to ensure that one end of the transmission rod 133 moves in the horizontal direction under the drive of the motor 132, and then under the restriction of the first guide limit groove 1341, the other end of the transmission rod 133 slides in the second guide limit groove 1342, so that the transmission rod 133 moves on the side plate 134 to drive the ink stack platform 11 to rise and fall. That is, in this solution, the horizontal movement driven by the motor 132 is converted into the up and down movement of the ink stack platform 11. Compared with directly driving the ink stack platform 11 to move up and down, this solution can reduce the output power of the motor 132 and improve the movement stability of the ink stack platform 11.

[0084] The transmission rod 133 is disposed on the side of the side plate 134 facing away from the ink stack platform 11. Therefore, one side of the transmission rod 133 is simultaneously mounted on the second guide limit slot 1342 and is transmission-connected to the ink stack platform 11, thereby ensuring the smooth movement of the ink stack platform 11 and improving the structural compactness of the ink stack device 1. Specifically, a transmission shaft 1331 is provided at both ends of the transmission rod 133. One end of one of the two transmission shafts 1331 is connected to the transmission rod 133, and the other end passes through the first guide limit slot 1341 to be transmission-connected to the motor 132; the other end of the transmission rod 133 is connected to the transmission rod 133, and the other end passes through the second guide limit slot 1342 to be transmission-connected to the ink stack platform 11. Of course, in other embodiments, the transmission rod 133 can also be disposed between the side plate 134 and the ink stack platform 11. In this case, one side of the transmission rod 133 is rotationally connected to the ink stack platform 11, and the other side is slidably mounted in the second guide limit slot 1342.

[0085] To facilitate the movement of the transmission rod 133 driven by the motor 132, in one embodiment, the lifting mechanism 13 also includes a screw rod 135 parallel to the extension direction of the first guide limit groove 1341, and a movable part 136 threadedly connected to the screw rod 135. The screw rod 135 is transmission-connected to the motor 132, and one end of the transmission rod 133 is movably installed in the first guide limit groove 1341 and transmission-connected to the movable part 136.

[0086] Specifically, the support seat 131 has four side panels 134, and the four side panels 134 include two first side panels 1343 and two second side panels 1344 that are arranged opposite to each other, and the first side panels 1343 and the second side panels 1344 are arranged adjacent to each other. The motor 132 is installed on the bottom plate 137 or the first side panel 1343, and the screw rod 135 is installed on at least one of the two first side panels 1343, and is suspended above the bottom plate 137, and is parallel to the bottom of the ink stack platform 11, and the screw rod 135 is transmission-connected to the output end of the motor 132, so that the motor 132 can drive the screw rod 135 to rotate stably in the support seat 131, thereby preventing the screw rod 135 from interfering with the bottom plate 137 and the side panel 134. Correspondingly, the transmission rod 133 is movably mounted on the second guide limit groove 1342 of the second side plate 1344, so that when the screw rod 135 rotates, it can drive the movable part 136 to move along the axial direction of the screw rod 135 (between the two first side plates 1343), thereby driving one end of the transmission rod 133 away from the ink stack platform 11 along the axial direction of the screw rod 135, that is, horizontally moving along the extension direction of the first guide limit groove 1341, and then making the other end of the transmission rod 133 move vertically along the extension direction of the second guide limit groove 1342, thereby driving the ink stack platform 11 to rise and fall.

[0087] The screw rod 135 has high transmission accuracy and more stable transmission, which helps to improve the movement stability of the transmission rod 133, thereby further ensuring the movement smoothness and movement accuracy of the ink stack platform 11. In order to improve the smoothness of transmission, the two second side plates 1344 are each equipped with a transmission rod 133, so that the opposite sides of the ink stack platform 11 can be driven by the driving force, thereby ensuring the movement smoothness of the ink stack platform 11. In order to further ensure stable stability, each second side plate 1344 is equipped with multiple transmission rods 133, and the multiple transmission rods 133 are arranged at intervals on the second side plate 1344 and are respectively connected to the ink stack platform 11 and the movable member 136, so that the multiple transmission rods 133 move synchronously and jointly drive the ink stack platform 11 to rise and fall. Of course, in other embodiments, each second side plate 1344 can also be equipped with only one transmission rod 133.

[0088] In one embodiment, to facilitate the installation of the movable member 136, the movable member 136 includes a first plate 1361 perpendicular to the axial direction of the screw rod 135, and a second plate 1362 parallel to the screw rod 135. The first plate 1361 and the second plate 1362 are bent and connected, and the first plate 1361 is provided with a threaded hole, which is threadedly connected to the screw rod 135 for transmission with the screw rod 135; the second plate 1362 is formed with a bent flange 1363 on the side near the second side plate 1344, and the bent flange 1363 is connected to the transmission rod 133, so that the movable member 136 is respectively connected to the screw rod 135 and the transmission rod 133. In this way, compared with the movable member 136 directly configured as a transmission block, the movable member 136 formed by two bent plates has a smaller transmission area with the screw rod 135 (reducing friction), is lighter in weight, and occupies less space in the support base 131. The second plate 1362 is disposed between the screw rod 135 and the bottom plate 137, thereby reducing the internal installation space occupied by the movable member 136 in the support base 131. The width of the second plate 1362 is slightly smaller than the width of the bottom plate 137, so that the two second side plates 1344 can guide the movement of the second plate 1362 to a certain extent. This also reduces the connection distance between the movable member 136 and the transmission rod 133, thereby further improving the movement smoothness of the movable member 136. In other embodiments, the movable member 136 is configured as a transmission block.

[0089] See also Figure 1 、 Figure 3 、 Figure 5 and Figure 8 In an embodiment of the present invention, the ink stack platform 11 is provided with a trigger 118, which is used to detect whether the print head 2 is located on the ink stack device 1, so as to trigger the ink stack device 1 to work. Specifically, when the print head 2 moves to a preset position, the trigger 118 can be triggered, thereby sending an operation signal to the ink stack device 1, and when the trigger 118 is not triggered, a stop operation signal can be sent to the ink stack device 1, so as to avoid a certain probability of the ink stack device 1 idling or leaking due to the offset of the print head 2 from the ink stack device 1, thereby ensuring that the ink stack device 1 accurately cleans the print head 2. Among them, the trigger 118 can have multiple types, such as a travel switch, a sensor, etc., and the setting position of the trigger 118 can also have multiple types, and can be set on the upper surface of the ink stack platform 11, or outside the ink stack platform 11. The present application does not limit the type and installation position of the trigger 118, and it is sufficient to achieve corresponding detection of the print head 2 and the ink stack device 1.

[0090] Optionally, the ink stack platform 11 has a cleaning surface 117, the cleaning member 116 and the dirt collecting tank 111 are both arranged on the cleaning surface 117, and the cover plate 12 is also located on the cleaning surface 117; the trigger member 118 includes a protrusion 115 arranged on the cleaning surface 117 (the protrusion 115 extends out of the cover plate 12), and a groove is correspondingly provided on the print head 2, and a sensing member is provided in the protrusion 115 and the groove, and the protrusion 115 can be inserted into the groove to trigger the sensing member. Specifically, the cleaning surface 117 is the side of the ink stack platform 11 facing the print head 2, that is, the upper surface of the ink stack platform 11. The trigger member 118 includes a protrusion 115 provided on the cleaning surface 117. By providing a groove at the corresponding position of the nozzle 21, the print head 2 can be positioned above the ink stack device 1, and when the cleaning member 116 of the ink stack device 1 contacts the nozzle 21, the protrusion 115 is inserted into the groove. At this time, a corresponding triggering sensor can be provided on the protrusion 115 or in the groove, so that the controller of the inkjet printer 100 can know that the print head 2 is correspondingly provided on the ink stack device 1. At this time, the ink stack device 1 can be stably started to clean the nozzle 21, thereby achieving precise positioning of the print head 2 and the ink stack device 1. In other embodiments, the trigger member 118 is a groove provided on the ink stack platform 11, and a protrusion can be provided on the print head 22.

[0091] Optionally, the inductive element is configured as a sensor, which may be a pressure-sensitive sensor, a distance-measuring sensor, a photoelectric sensor, a Hall sensor, etc. In other embodiments, the inductive element may be a travel switch, etc.

[0092] The present invention also proposes an inkjet printer 100, which includes a print head 2 and an ink stack device 1. The specific structure of the ink stack device 1 refers to the above embodiment. Since the inkjet printer 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0093] For ease of understanding and explanation, Figure 1 and Figure 2 The directions indicated by the coordinate system shown in the figure are for reference, where the first direction is the direction of the x-axis, which is parallel to the length direction of the printing table 3, and the second direction is the direction of the y-axis, which is parallel to the width direction of the printing table 3; the positive direction of the x-axis is right, and the negative direction of the x-axis is left; the positive direction of the y-axis is front, and the negative direction of the y-axis is back.

[0094] The printhead 2 may integrate ink nozzles, control components, and other components to precisely spray ink onto printed materials. The principle by which the printhead 2 controls the amount of ink ejected to perform printing operations is conventional, and therefore the structure of the printhead 2 is not limited. Furthermore, the printhead 2 may also be equipped with a camera assembly and a detection assembly to monitor the print path and operating status of the printhead 2.

[0095] The movement of the print head 2 on the printing table 3 can be driven by a track drive device, or by a device such as a robotic arm. This application does not limit the method of movement of the print head 2; it is sufficient that the print head 2 can move on the printing table 3. This allows the print head 2 to perform printing operations along a specific movement path, so that the print head 2 can better spray ink on the printing material to form the desired image or text. It should be noted that the inkjet printer 100 includes a drive device disposed externally to the print head 2, and the print head 2 can be in transmission connection with the drive device. During use, the print head 2 can be driven by the drive mechanism to move relative to the printing material to a corresponding position on the printing material. Exemplarily, a support frame 31 is provided above or on one side of the printing table 3, and a drive mechanism is provided on the support frame 31. The print head 2 is connected to the drive mechanism and can move relative to the support frame 31. The drive mechanism drives the print head 2 to move back and forth along a first direction. The support frame 31 is connected to the printing table 3, so that the printing table 3 can form a bearing structure for the operation and processing of the entire machine, so that the print head 2 can stably print the printing material carried on the printing table 3, ensuring the stable operation of the inkjet printer 100.

[0096] In addition, the inkjet printer 100 also includes an ink supply cartridge 4, which is used to supply ink to the print head 3. Therefore, the ink supply cartridge 4 can be connected to the print head 2 through a pipeline to deliver ink, or the ink supply cartridge 4 can be set in the print head 2 to directly deliver ink to the nozzle 21 in the print head 2. Of course, the ink supply cartridge 4 can also use other methods to supply ink to 2, as long as the ink can be stably delivered to the print head 2 for inkjet printing. This application is not limited to this. Exemplarily, the ink supply cartridge 4 is arranged above the printing table 3 and is located on one side of the printing table 3 along the second direction. The ink supply cartridge 4 is connected to the nozzle 21 of the print head 2 through an ink supply pipeline.

[0097] See Figure 1 and Figure 2 The inkjet printer 100 can be equipped with at least two ink cartridges 4. By injecting different colored inks into the at least two ink cartridges 4, the print head 2 can utilize different ink combinations to achieve a variety of color inkjet effects, thereby enabling the inkjet printer 100 to better process desired images or text on printed materials. In this case, the at least two ink cartridges 4 can be arranged and connected in sequence to form a single unit, facilitating assembly and disassembly of the ink cartridges 4. A sequential assembly and disassembly structure can be provided between the at least two ink cartridges 4, so that the at least two ink cartridges 4 can only be removed by a specific insertion and removal sequence. In other embodiments, the inkjet printer 100 can also be equipped with a single ink cartridge 4.

[0098] The above are merely exemplary embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
