[0045] The utility model provides an ink stack assembly for an inkjet printer 100, see Figure 1 and Figure 2 The inkjet printer 100 includes a printing table 8 and a print head 82. The print head 82 reciprocates on the printing table 8 to print patterns on the printing material. The ink stack assembly includes an ink stack 1, and an infusion line 2 and a drainage line 3 connected to the ink stack 1. The ink stack 1 is used to clean and / or moisturize the nozzle 821 of the print head 82, which helps to avoid the ink condensation at the nozzle 821 and clogging the nozzle 821. When the print head 82 performs a printing job for a certain period of time or pauses the job and is in standby mode, the print head 82 can be adjusted to a trimming state so that the print head 82 moves to the top of the ink stack 1 for cleaning or docking, so that the print head 82 can better perform subsequent printing jobs, further improving the practicality and reliability of the inkjet printer 100. The infusion line 2 is used to provide cleaning liquid to the ink stack 1, and the drainage line 3 is used to collect waste liquid generated after the ink stack 1 is cleaned.

[0046] The inkjet printer 100 may be a thermal inkjet printer 100, a piezoelectric inkjet printer 100, 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-jet printer ("Direct to Garment," a printer that prints directly onto textiles). Any device capable of jetting ink to perform printing operations 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 by the inkjet printer 100 is sufficient.

[0047] See also Figures 3 to 9In one embodiment of the present invention, the ink stack 1 also includes a support seat 11 and an ink pad 124. The ink pad 124 is arranged on the ink stack platform 12. The ink pad 124 is used to clean and / or moisturize the nozzle 821 of the print head 82. The ink stack platform 12 is installed on the support seat 11; the infusion pipeline 2 is at least partially located in the support seat 11 and is connected to the ink pad 124 to provide cleaning liquid to the ink pad 124; the discharge pipeline 3 is at least partially located in the support seat 11 and is connected to the ink pad 124 to discharge the waste liquid of the ink pad 124; the limiting structure 13 is provided on the support seat 11 and / or the ink stack platform 12, and is connected to the infusion pipeline 2 and the discharge pipeline 3 to limit the running direction of the infusion pipeline 2 and the discharge pipeline 3 in the support seat 11.

[0048] Specifically, an ink pad 124 is provided on the ink stack platform 12. When the print head 82 is placed on the ink stack 1 for cleaning, the nozzle 821 can be brought into contact with the ink pad 124, and the infusion line 2 is connected to the ink pad 124, thereby providing cleaning liquid to the ink pad 124 to maintain the print head 82. The waste liquid generated after cleaning is collected by the discharge line 3 and discharged from the ink stack 1 in time.

[0049] The ink stack 1 includes a support base 11, which is generally box-shaped. The ink stack platform 12 is mounted on the support base 11. The infusion line 2 and the drainage line 3 can extend into the support base 11 and extend within the support base 11 to connect to the ink pad 124. However, if the routing of the infusion line 2 and the drainage line 3 within the support base 11 is not reasonable, not only will it occupy a large amount of space, but the support base 11 often also integrates a drive structure and other auxiliary structures. As a result, the infusion line 2 and the drainage line 3 may interfere with other structures within the ink stack 1. This not only increases the complexity of the device, but may also lead to an unstable supply of cleaning liquid or incomplete waste liquid recovery, affecting the overall performance and reliability of the printer. Therefore, the support seat 11 and / or the ink stack platform 12 is provided with a limiting structure 13, which can limit the running direction of the infusion pipeline 2 and the drainage pipeline 3 in the support seat 11, thereby facilitating the limitation of the running path of the infusion pipeline 2 and the drainage pipeline 3 in the support seat 11, thereby improving the rationality of the distribution of the infusion pipeline 2 and the drainage pipeline 3 in the support seat 11.

[0050] The limiting structure 13 can be provided only on the support base 11 or only on the ink stack platform 12. When provided on the ink stack platform 12, the limiting structure 13 is usually provided on the side of the ink stack platform 12 facing the support base 11, that is, provided on the bottom of the ink stack platform 12. The limiting structure 13 can also be provided on both the support base 11 and the ink stack platform 12. The limiting structure 13 can be connected to the infusion pipeline 2 and the drainage pipeline 3 respectively, that is, the limiting structure 13 can only limit the position of one pipeline; the limiting structure 13 can also be connected to the infusion pipeline 2 and the drainage pipeline 3 at the same time, that is, the limiting structure 13 can limit the position of multiple pipelines, thereby facilitating the rational arrangement of the infusion pipeline 2 and the drainage pipeline 3, and on the other hand, it can also save the number of limiting structures 13, thereby facilitating the fixation of the infusion pipeline 2 and the drainage pipeline 3.

[0051] In this embodiment, the support seat 11 is roughly arranged in a rectangular shape. In other embodiments, the support seat 11 can also be cylindrical or other irregular shapes. The corresponding ink stack 1 as a whole can be arranged in a rectangular shape, a cube or a cylinder, or other irregular shapes.

[0052] To facilitate the ink pad 124 to clean the nozzle 821, preferably, see Figure 1 The ink stack 1 is positioned on the movement path of the print head 82. In one embodiment, the print head 82 slides back and forth on the printing table 8 along a first direction X. The ink stack 1 is correspondingly positioned on one side of the printing table 8 along the first direction X, that is, the ink stack 1 is positioned on the left or right side of the printing table 8. This facilitates movement of the print head 82 between the ink stack 1 and the printing table 8, reduces the movement path from the print head 82 to the ink stack 1, and achieves a more compact structural design for the inkjet printer 100. Of course, in other embodiments, the ink stack 2 and the printing table 8 can also be arranged in other ways, which are not limited to this embodiment. Any arrangement is acceptable as long as the ink stack 1 can clean the print head 82.

[0053] For ease of understanding and explanation, Figure 1 The directions indicated by the coordinate system shown in the figure are for reference, wherein the first direction is the direction of the x-axis, which is parallel to the length direction of the printing table 8, and the second direction is the direction of the y-axis, which is parallel to the width direction of the printing table 8; 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.

[0054] In this embodiment, the nozzle 821 is cleaned by the ink pad 124. In other embodiments, refer to Figures 2 to 8The ink stack platform 12 may further be provided with a cleaning scraper 125. Preferably, the cleaning scraper 125 and the ink pad 124 are arranged side by side along the first direction, and the cleaning scraper 125 is arranged closer to the printing table 8 than the ink pad 124. That is, when the print head 82 moves from the printing table 8 to the ink stack 1, it first contacts the cleaning scraper 125 and then contacts the ink pad 124, so that the condensed ink on the nozzle 821 can be better scraped off under the action of the cleaning scraper 125, and then the nozzle 821 can be kept in a good state for printing operations after being cleaned by the ink pad 124.

[0055] To reduce the risk of waste liquid generated during the cleaning process accidentally flowing out of the ink stack platform 12, a sump 121 is provided on the ink stack platform 12. Both an ink pad 124 and a cleaning scraper 125 are located within the sump 121. When the ink pad 124 cleans the nozzles 821 of the print head 82, waste liquid flows out of the ink pad 124 and into the sump 121, thereby temporarily storing the waste liquid. Similarly, waste scraped off by the cleaning scraper 125 also falls into the sump 121, facilitating unified disposal. To facilitate the discharge of waste liquid from the sump 121, in one embodiment, the drainage line 3 is also connected to the sump 121, allowing the waste liquid in the sump 121 to be discharged from the ink stack 1 together with the waste liquid discharged from the ink pad 12, thereby facilitating the discharge of waste liquid from the ink stack 1. In other embodiments, an additional drainage structure may be provided to connect to the sump 121 to discharge the waste liquid in the sump 121; or the sump 121 may be cleaned manually. In this case, in order to facilitate the discharge of the waste liquid in the sump 121, a valve body may be provided near the bottom of the sump 121. When the waste liquid in the sump 121 needs to be discharged, it is only necessary to open the valve body without moving the entire ink stack 1.

[0056] The shape of the sewage collecting tank 121 can be a regular shape, such as a square, a circle, etc. Of course, the shape of the sewage collecting tank 121 can also be an irregular shape, which is not limited in this application.

[0057] In one embodiment, the ink pad 124 includes an ink pad base 1242 and a cleaning pad provided above the ink pad base 1242. The ink pad base 1242 is fixed in the dirt collecting tank 111 to install the ink pad 124 in the dirt collecting tank 111, and a liquid inlet channel and a liquid discharge channel are provided inside the ink pad base 1242. One end of the liquid inlet channel is connected to the infusion pipeline 2, and the cleaning pad is provided at the other end of the cleaning channel. One end of the liquid discharge channel is connected to the liquid discharge pipeline 3, and the other end is also connected to the ink pad 124, so that the liquid inlet channel fills the cleaning pad with liquid to soak the cleaning pad and force out the waste liquid in the cleaning pad. At the same time, the liquid discharge channel absorbs the waste liquid discharged by the cleaning pad and discharges it to the liquid discharge pipeline 3, thereby achieving the effect of cleaning the ink pad 124 and maintaining the wetness of the ink pad 124.

[0058] When the drainage line 3 needs to drain waste liquid from the sump 121, one end of the drainage channel connects to the drainage line 3, while the other end connects to the ink pad 124, which in turn connects to the sump 121. This allows the drainage line 3 to connect to the sump 121 through the ink pad 124, eliminating the need for additional holes in the sump 121. This facilitates the installation of the drainage line 3 and reduces the possibility of accidental leakage from the sump 121. Furthermore, because both the infusion line 2 and the drainage line 3 are connected to the ink pad 124 and extend along roughly the same path, the infusion line 2 and the drainage line 3 can extend side by side. A single retaining structure 13 can simultaneously retain the drainage line 3 and the infusion line 2, reducing the number of retaining structures 13 and the space required for the drainage line 3 and the infusion line 2.

[0059] The cleaning pad can be a cleaning pad that has a certain function of absorbing condensed ink, or a cleaning pad that has a certain function of wiping condensed ink, etc. The present application does not limit the type of cleaning pad, as long as it can achieve the function of moisturizing and cleaning the nozzle 821. The liquid can be clean water or a detergent.

[0060] To facilitate the installation of the ink pad 124 on the ink stack platform 12, in one embodiment, refer to Figure 7 and Figure 8 The bottom of the ink pad 124 is provided with a laterally protruding mounting protrusion 1241 on one side, and a mounting hole is opened corresponding to the mounting protrusion 1241. The fastener passes through the mounting hole and is fastened to the bottom of the dirt collecting tank 121, thereby pressing and fixing the ink pad 124 in the dirt collecting tank 121. The dirt collecting tank 121 is provided with a through hole 1211 at the bottom of the ink pad 124, so that the infusion pipeline 2 and the discharge pipeline 3 pass through the through hole 1211 to connect with the ink pad 124, so as to provide liquid to the ink pad 124 and recover waste liquid. In order to ensure the sealing between the ink pad 124 and the through hole 1211, a sealing ring can be provided between the bottom of the ink pad base 1242 and the bottom wall of the dirt collecting tank 111. The sealing ring is arranged around the periphery of the through hole 1211, and the sealing ring is pressed against the bottom of the dirt collecting tank 111 through the ink pad 124 to ensure the sealing of the bottom of the dirt collecting tank 111.

[0061] Reference Figures 3 to 9 In an embodiment of the present utility model, the support seat 11 is provided with a lifting mechanism 14, the lifting mechanism 14 is transmission-connected to the ink stack platform 12, the limiting structure 13 is arranged in the ink stack 1, and is staggered with the lifting mechanism 14 so that the infusion pipeline 2 and the discharge pipeline 3 avoid the lifting mechanism 14.

[0062] Specifically, the lifting mechanism 14 is in driving connection with the ink stack platform 12, enabling the ink stack platform 12 to have a cleaning state close to the print table 8, and a retracted state away from the print table 8. It will be appreciated that when the print head 82 needs to be cleaned, the lifting mechanism 14 can be controlled to drive the ink stack platform 12 upward, allowing the ink pad 124 to contact the nozzle 821 for cleaning. Conversely, when the print head 82 needs to be away from the nozzle 821, the lifting mechanism 14 can be controlled to drive the ink stack platform 12 downward, allowing the ink stack platform 12 to move away from the print head 82 to avoid movement, thereby facilitating automated control of the ink stack 1. The lifting mechanism 14 is generally arranged below the ink stack platform 12 and is at least partially arranged in the support seat 11. The limiting structure 13 is arranged in the ink stack 1 and is staggered with the lifting mechanism 14. If a certain interval is set between the limiting structure 13 and the lifting mechanism 14, thereby limiting the arrangement of the infusion pipeline 2 and the drainage pipeline 3 in the ink stack 1, the infusion pipeline 2 and the drainage pipeline 3 can maintain a certain distance from the lifting mechanism 14 in space, thereby avoiding the lifting mechanism 14 and reducing the possibility of mutual interference between the two.

[0063] Among them, the lifting mechanism 14 drives the ink stack platform 12 to move up and down. Compared with driving the ink stack platform 12 to move horizontally, this solution can reduce the movement space required by the ink stack platform 12, which helps to miniaturize the equipment. Moreover, because the ink stack platform 12 will move within the ink stack 1, the length of the infusion pipeline 2 and the drainage pipeline 3 within the ink stack 1 has a certain margin, thereby reducing the infusion pipeline 2 and / or the drainage pipeline 3 from being torn off during the movement of the ink stack platform 12. The limiting structure 13 only serves to limit the extension path of the infusion pipeline 2 and / or the drainage pipeline 3, reducing the deflection of the infusion pipeline 2 and / or the drainage pipeline 3 within the ink stack 1, but does not affect the axial movement of the infusion pipeline 2 and / or the drainage pipeline 3 relative to the limiting structure 13, so as to ensure that the infusion pipeline 2 and / or the drainage pipeline 3 can move axially with the lifting and lowering of the ink stack platform 12.

[0064] Furthermore, the support base 11 includes a bottom plate 111 and a plurality of side plates 112 provided on the bottom plate 111. The lifting mechanism 14 includes a motor 141, a screw rod 142 and a lifting structure 146. The motor 141 is fixed to the bottom plate 111 or one of the side plates 112. The screw rod 142 is transmission-connected to the motor 141 and rotationally connected to at least one of the side plates 112. The lifting structure 146 is transmission-connected to the screw rod 142 and the ink stack platform 12. The rotation of the screw rod 142 can drive the lifting structure 146 to move, thereby raising and lowering the ink stack platform 12.

[0065] The limiting structure 13 is provided on the bottom plate 111 and the ink stack platform 12 and avoids the screw rod 142 and the lifting structure 146 so that the infusion pipeline 2 and the discharge pipeline 3 are limited to extend at the bottom of the bottom plate 111 and / or the ink stack platform 12.

[0066] Specifically, the bottom plate 111 is located at the bottom of the ink stack platform 12, and the side plates 112 are arranged around the bottom plate 111, so that the support seat 11 is box-shaped as a whole. The ink stack platform 12 and the bottom plate 111 are arranged opposite to each other, and can be raised and lowered away from or close to the bottom plate 111. The side plates 112 are arranged at an angle to the ink stack platform 12 and are parallel to the lifting direction of the ink stack platform 12, thereby improving the movement reliability of the ink stack platform 12. The support seat 11 has four side panels 112, and the four side panels 112 include two first side panels 1123 and two second side panels 1124 that are arranged opposite to each other, and the first side panels 1123 and the second side panels 1124 are arranged adjacent to each other. The motor 141 is installed on the bottom plate 111 or the first side panel 1123, and the screw rod 142 is installed on at least one of the two first side panels 1123, and is suspended above the bottom plate 111, and is parallel to the bottom of the ink stack platform 12, and the screw rod 142 is transmission-connected to the output end of the motor 141, so that the motor 141 can drive the screw rod 142 to rotate stably in the support seat 131, thereby preventing the screw rod 142 from interfering with the bottom plate 111 and the side panel 112.

[0067] Exemplarily, the motor 141 is fixed to the first side plate 1123 and is arranged on the outside of the support base 11. One end of the screw rod 142 passes through the first side plate 1123 and is installed on the output end of the motor 141, and the other end is rotatably connected to the other first side plate 1123. This can not only ensure the stable movement of the screw rod 142, but also reduce the occupation of the internal space of the support base 11 by the motor 141. Of course, in other embodiments, the motor 141 can also be arranged on the inner side of the support base 11. The installation method of the motor 141 and the screw rod 142 is not limited to this. As long as the stable transmission of the motor 141 and the screw rod 142 can be achieved, it is within the protection scope of this solution. In order to further ensure the smoothness of the movement of the ink stack platform 12 and improve the smoothness and accuracy of the transmission, the screw rod 142 and the motor 141 are often connected by a coupling 145.

[0068] The lifting structure 146 is respectively connected to the screw rod 142 and the ink stack platform 12, so that the motor 141 drives the screw rod 142 to rotate, and then drives the lifting structure 146 to move, thereby driving the ink stack platform 12 to rise and fall, and the transmission accuracy of the screw rod 142 is high and the transmission is more stable. When the infusion line 2 and / or the drainage line 3 are arranged, if the distance to the screw rod 142 is too close, the screw rod 142 may accidentally reel in the infusion line 2 and / or the drainage line 3 during the rotation process, thereby damaging the infusion line 2 and / or the drainage line 3 and affecting the normal lifting and lowering of the ink stack platform 12. Therefore, the limiting structure 13 is spaced apart from the screw rod 142 to avoid the screw rod 142 and reduce the possibility of damaging the infusion line 2 and the drainage line 3; and when the ink stack platform 12 is lifted and lowered normally, the ink stack platform 12 and the lifting structure 146 may jointly squeeze the infusion line 2 and / or the drainage line 3, or the lifting structure 146 itself squeezes the infusion line 2 and / or the drainage line 3, causing the infusion line 2 and / or the drainage line 3 to be blocked, affecting the reliability of the ink stack 1, so the limiting structure 13 and the lifting structure 146 have a certain spatial interval, so that a certain safety distance is formed between the two. Some avoidance structures such as avoidance grooves 1444 can also be set on the lifting structure 146, so that when the ink stack platform 12 descends, there is enough space between the lifting structure 146 and the ink stack platform 12 for the infusion line 2 and / or the drainage line 3 to pass through, thereby reducing the risk of the infusion line 2 and / or the drainage line 3 being squeezed; and / or, the limiting structure 13 is provided on the ink stack platform 12, that is, when the infusion line 2 and the drainage line 3 pass through between the ink stack platform 12 and the screw rod 142, the infusion line 2 and the drainage line 3 can extend as close to the ink stack platform 12 as possible, thereby reducing the occupation of the bottom space of the ink stack platform 12 by the infusion line 2 and the drainage line 3, and reducing movement interference.

[0069] In one embodiment, referring to Figures 5 to 7 The lifting structure 146 includes a movable part 144 and a transmission rod 143. The movable part 144 is threadedly connected to the screw rod 142. The side plate 112 is provided with a first guide limit groove 1121 and a second guide limit groove 1122 which are arranged at an angle, and the second guide limit groove 1122 extends along the lifting direction of the ink stack platform 12. One end of the transmission rod 143 is movably installed in the first guide limit groove 1121 and is transmission-connected to the movable part 144. The other end of the transmission rod 143 is movably installed in the second guide limit groove 1122 and is connected to the ink stack platform 12.

[0070] Specifically, the movable member 144 is threadedly connected to the screw rod 142, so that when the screw rod 142 rotates, it can drive the movable member 144 to slide back and forth along the axial direction of the screw rod 142 (between the two first side plates 1123). The first guide limit groove 1121 and the second guide limit groove 1122 are both provided on the second side plate 1124, and the first guide limit groove 1121 extends vertically, and the second guide limit groove 1122 extends horizontally. Therefore, one end of the transmission rod 143 is movably mounted on the first guide limit groove. The first guide limit slot 1121 is connected to the movable member 144, and the other end is movably mounted in the second guide limit slot 1122 and connected to the ink stack platform 12, so that one end of the transmission rod 143 moves horizontally under the drive of the motor 141, and then, under the restriction of the first guide limit slot 1121, the other end of the transmission rod 143 slides up and down in the second guide limit slot 1122, thereby causing the transmission rod 143 to move on the side plate 134 to drive the ink stack platform 12 to rise and fall. That is, in this solution, the horizontal motion driven by the motor 141 is converted into the up and down motion of the ink stack platform 12. Compared with directly driving the ink stack platform 12 to move up and down, this solution can reduce the output power of the motor 141 and improve the movement stability of the ink stack platform 12.

[0071] The movable member 144 includes a first plate 1441 and a second plate 1442 that are bent and connected. The first plate 1441 is perpendicular to the axial direction of the screw rod 142, and the second plate 1442 is parallel to the screw rod 142. The first plate 1441 is provided with a threaded hole that is threadedly connected to the screw rod 142 for transmission with the screw rod 142. The second plate 1442 is formed with a bent flange 1443 on the side near the second side plate 1124. The bent flange 1443 is connected to the transmission rod 143, so that the movable member 144 is respectively connected to the screw rod 142 and the transmission rod 143. Compared with a direct configuration as a transmission block, the movable member 144 formed by two bent transmission plates has a smaller transmission area between the movable member 144 and the screw rod 142 (reducing friction), is lighter in weight, and occupies less space in the support seat 131 (making the space between the second plate 1442 and the ink stack platform 12 larger). The second plate 1442 is positioned between the screw rod 142 and the base plate 111, thereby reducing the space occupied by the movable member 144 between the screw rod 142 and the ink stack platform 12, thereby facilitating the placement of the infusion line 2 and the drainage line 3 at the bottom of the ink stack platform 2. The width of the second plate 1442 is slightly smaller than that of the base plate 111, allowing the two second side plates 1124 to guide the movement of the second plate 1442 to a certain extent. This also reduces the connection distance between the movable member 144 and the transmission rod 143, further improving the smoothness of the movement of the movable member 144. In other embodiments, the movable member 144 is configured as a transmission block.

[0072] In addition, an avoidance groove 1444 can be provided on the first plate 1441, and the infusion pipeline 2 and the drainage pipeline 3 extend through the avoidance groove 1444 to the bottom of the ink stack platform 12, so that when the ink stack platform 12 is pressed down to the limit, the infusion pipeline 2 and the drainage pipeline 3 are located in the avoidance groove 1444, thereby preventing the first plate 1441 and the ink stack platform 12 from squeezing the infusion pipeline 2 and the drainage pipeline 3.

[0073] Among them, the transmission rod 143 is usually arranged on one side of the ink stack platform 12, and transmission shafts are provided at both ends of the transmission rod 143. One end of one of the two transmission shafts is connected to the transmission rod 143, and the other end passes through the first guide limit groove 1121 to be transmission-connected to the motor 141; one end of the other is connected to the transmission rod 143, and the other end passes through the second guide limit groove 1122 to be transmission-connected to the ink stack platform 12. In order to improve the lifting and lowering stability of the ink stack platform 12, transmission rods 143 are provided on the opposite sides of the ink stack platform 12, and the two transmission rods 143 are respectively provided on two oppositely arranged second side plates 1124, so that the opposite sides of the ink stack platform 12 can be subjected to driving force in the same direction, thereby ensuring the movement stability of the ink stack platform 12. Therefore, when the infusion pipeline 2 and the drainage pipeline 3 are connected to the ink pad 124 from the bottom of the ink stack platform 12, they often extend from the side of the ink stack platform 12 located between the two transmission rods 143 into the space between the ink stack platform 12 and the bottom plate 111, thereby reducing the possibility of interference between the infusion pipeline 2, the drainage pipeline 3 and the transmission rod 143 during movement.

[0074] In another embodiment, the lifting structure 146 includes a first rocker arm and a second rocker arm that are staggered, and 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 rotatably connected to the ink stack platform 12, and at least one of the other ends of the first rocker arm and the second rocker arm is transmission-connected to the screw rod 142, and the screw rod 142 rotates to drive 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 12. That is, in this solution, the specific structure of the lifting structure 146 is not restricted. As long as it can be combined with the screw rod 142 to realize the lifting and lowering of the ink stack platform 12, it is within the protection scope of this solution.

[0075] See also Figure 3 and Figure 4In an embodiment of the present utility model, the ink stack platform 12 includes a first area 122 and a second area 123 respectively arranged on opposite sides of the screw rod 142, and the first area 122 and the second area 123 are both provided with an ink pad 124, the infusion line 2 includes a first infusion line 21 and a second infusion line 22, and the discharge line 3 includes a first discharge line 31 and a second discharge line 32, the first infusion line 21 and the first discharge line 31 are connected to the ink pad 124 in the first area 122, and the limiting structure 13 includes a first limiting member 133, the first limiting member 133 is arranged on the bottom plate 111 or the ink stack platform 12, and the first limiting member 133 fixes the second infusion line 22 and the second discharge line 32 so that the second infusion line 22 and the second discharge line 32 are bypassed from above or below the screw rod 142 and connected to the ink pad 124 in the second area 123.

[0076] In this embodiment, the inkjet printer 100 can be a white ink heat transfer printer. The DTF ink used is typically composed of four colors (CMYK) ("Cyan Magenta Yellow blacK," for printing four-color separation) and white. Accordingly, the print head 8 is equipped with two nozzles 82: one nozzle 82 is a color ink nozzle 82 for color ink printing corresponding to the four CMYK colors; the other nozzle 82 is a white ink nozzle 82 for white ink printing. During use, the print head 8 can first print a color pattern or text on the printed material using one nozzle 82, and then use the other nozzle 82 to print a layer of white ink over the color pattern. This allows the printed color pattern or text to appear more vivid by printing white ink on the printed material.

[0077] The two nozzles 82 are arranged at intervals. For example, if the print head 8 reciprocates in a first direction, the two nozzles 82 are arranged side by side in a second direction. Therefore, the ink stack platform 12 is divided into a first area 122 and a second area 123. Each area 122 and the second area 123 is provided with an ink pad 124. These areas are arranged side by side in the second direction, so that the ink pads 124 in the first and second areas 122 and 123 respectively clean and maintain the two nozzles 82. In other words, the number and arrangement of the ink pads 124 often depend on the position and number of the nozzles 821. In other embodiments, the number of nozzles 82 can be one or more than three. Therefore, the number of ink pads 124 can be one or more than two, such as three or four. Accordingly, the ink stack platform 12 can be divided into a first area 122, a second area 123, and a third area, etc. Each area requires a corresponding infusion line 2 connected thereto. To ensure the timely discharge of waste liquid, each area also requires a corresponding drainage line 3. Correspondingly, both the first area 122 and the second area 123 are provided with a sewage collecting tank 121 , and the sewage collecting tank 121 of the first area 122 and the sewage collecting tank 122 of the second area 123 can be directly connected to facilitate the overall cleaning of the sewage collecting tank 121 .

[0078] In this solution, the first area 122 and the second area 123 are respectively arranged on opposite sides of the screw rod 142. Therefore, the infusion line 2 includes a first infusion line 21 and a second infusion line 22, and the drainage line 3 includes a first drainage line 31 and a second drainage line 32. The first infusion line 21 and the first drainage line 31 are connected to the ink pad 124 of the first area 122, and the second infusion line 22 and the second drainage line 32 need to bypass the screw rod 142 from above or below to connect to the second area 124. To reduce interference with the ink pad 124 in area 123, the second infusion line 22 and the second drainage line 32 need to maintain a safe distance from the screw rod 142 or the coupling 145 when bypassing the screw rod 142 or the coupling 145. Therefore, a first limiter 133 is provided. The first limiter 133 allows the second infusion line 22 and the second drainage line 32 to bypass the screw rod 142 from above or below and connect to the ink pad 124 in the second area 123, avoiding the screw rod 142.

[0079] Preferably, the first limiter 133 is arranged in an area on the bottom plate 111 opposite to the second area 123, so that the second infusion line 22 and the second drainage line 32 extend from the bottom plate 111, that is, avoid 142 from under the screw rod 142, that is, the second infusion line 22 and the second drainage line 32 pass through under the screw rod 142 or the coupling 145. On the one hand, it reduces the difficulty of installation, and on the other hand, it reduces the possibility that when the first limiter 133 fails accidentally, the second infusion line 22 and the second drainage line 32 directly fall onto the bottom plate 111, causing the screw rod 142 to accidentally reel in the second infusion line 22 and the second drainage line 32. In another embodiment, the first limit member 133 can also be arranged at a position corresponding to the second area 123 of the ink stack platform, that is, limiting the second infusion line 22 and the second drainage line 32 from passing over the top of the screw rod 142, thereby limiting the second infusion line 22 and the second drainage line 32 from bypassing over the top of the screw rod 142 or the coupling 145.

[0080] The area of ​​the base plate 111 opposite the second region 123, namely, the first stopper 133, is located at least on the side of the screw rod 142 proximate to the second region 123. This serves to both positionally limit the second infusion line 22 and the second drainage line 32 on the base plate 111 and restrict their rotational direction so that they extend toward the bottom of the ink stack platform 12 and connect to the ink pad 124. Two or more first stoppers 133 may be provided, with multiple first stoppers 133 located on opposite sides of the screw rod 142 to collectively limit the second infusion line 22 and the second drainage line 32. The first stopper 133 can simultaneously limit the second infusion line 22 and the second drainage line 32, thereby facilitating the limiting of the second infusion line 22 and the second drainage line 32 and reducing the number of first stoppers 133, thereby reducing the clutter of lines within the support base 11 and reducing the space occupied by the second infusion line 22 and the second drainage line 32. In other embodiments, the first stopper 133 is provided on each of the second infusion line 22 and the second drainage line 32.

[0081] Further preferably, the first position-limiting member 133 includes a position-limiting pressing piece, which presses the second infusion line 22 and the second drainage line 32 into the support seat 11. Specifically, the position-limiting pressing piece includes an arc-shaped protective portion and mounting portions provided on opposite sides of the arc-shaped protective portion. The mounting portions are used to install the position-limiting pressing piece, thereby ensuring that the position-limiting pressing piece can press the second infusion line 22 and the second drainage line 32 onto the bottom plate 111. The arc-shaped protective portion forms a space for the second infusion line 22 and the second drainage line 32 to pass through, thereby limiting the position of the second infusion line 22 and the second drainage line 32, ensuring that the second infusion line 22 and the second drainage line 32 are unobstructed, and ensuring that the second infusion line 22 and the second drainage line 32 can slide axially with the rise and fall of the ink stack platform 12.

[0082] In order to further limit the position of the infusion pipeline 2 and the drainage pipeline 3, in one embodiment, referring to Figure 9 The infusion pipeline 2 includes a first pipe joint 25 provided on the support base 11, the drainage pipeline 3 includes a second pipe joint 35 provided on the support base 11, and the limiting structure 13 also includes a second limiting member 134 provided on the side plate 112 or the bottom plate 111. The second limiting member 134 is arranged close to the first pipe joint 25 and the second pipe joint 35 to limit the extension of the infusion pipeline 2 and the drainage pipeline 3 on the side plate 112.

[0083] Exemplarily, the infusion pipeline 2 includes a first infusion pipeline section 23 and a second infusion pipeline section 24, the second infusion pipeline section 24 is arranged in the support base 11, and the support base 11 is provided with a first pipe joint 25, the first pipe joint 25 connects the first infusion pipeline section 23 and the second infusion pipeline section 24; the drainage pipeline 3 includes a first drainage pipeline section 33 and a second drainage pipeline section 34, the second drainage pipeline section 34 is arranged in the support base 11, the support base 11 is fixed with a second pipe joint 35, the second pipe joint 35 connects the first drainage pipeline section 33 and the second drainage pipeline section 34 ; The first pipe joint 25 and the second pipe joint 35 are both arranged at the connection position 1125, and the second limiting member 134 is arranged close to the connection position 1125, that is, the second infusion pipe section 24 and the second drainage pipe section 34 are limited by the second limiting member 134 at one end away from the ink stack platform 12, thereby ensuring the stable installation of the second infusion pipe section 24 and the second drainage pipe section 34 at one end away from the ink stack platform 12, and also ensuring the stable installation of the second infusion pipe section 24 and the first pipe joint 25, as well as the stable installation of the second drainage pipeline 32 and the second pipe joint 35.

[0084] The second position-limiting member 134 may have the same structural form as the first position-limiting member 133 , or may have different structural forms, as long as the infusion pipeline 2 and the drainage pipeline 3 can be positioned and installed on the side panel 112 .

[0085] See also Figures 5 to 8In an embodiment of the present invention, a through hole 1211 is formed at the bottom of the ink stack platform 12. The infusion line 2 and the drainage line 3 are disposed through the through hole 1211 and communicate with the ink pad 124. The infusion line 2 and the drainage line 3 each include a right-angle elbow 131 and a hose 135. One end of the right-angle elbow 131 is connected to the ink pad 124, and the other end is connected to the hose 135, so that the infusion line 2 and the drainage line 3 can be bent. Specifically, because the infusion line 2 and the drainage line 3 are generally flexible hoses, one end of the infusion line 2 and the drainage line 3 extends outward after extending from the bottom of the ink stack platform 12. However, due to the characteristics of their materials, the resulting bending angle is often large, and the extension path is difficult to control. This may cause contact with the screw rod 142 or the movable part 144, thereby affecting the normal operation of the ink stack 1. Therefore, a right-angle elbow 131 is provided, one end of the right-angle elbow 131 is connected to the ink pad 124, and the other end is connected to the hose 135. That is, the right-angle elbow 131 does not require the hose parts of the infusion line 2 and the discharge line 3 to be bent. Through the provision of the right-angle elbow 131, the bending position and bending angle of the infusion line 2 and the discharge line 3 can be controlled, thereby improving the reliability of the ink stack 1, and the right-angle elbow can be conveniently connected to the hose 135 and the ink pad 124, making assembly more convenient, thereby facilitating the assembly of the ink stack 1.

[0086] In other embodiments, shaping members may be provided on the infusion line 2 and the drainage line 3 to control the bending position and angle of the infusion line 2 and the drainage line 3. For example, the shaping member may be a bendable wire fixed along the axial direction of the infusion line 2 and the drainage line 3, thereby shaping the infusion line 2 and the drainage line 3 near the ink stack platform 12, thereby facilitating control of their bending angle and position. Alternatively, the shaping member may be configured as a rigid bending tube, which is sleeved over the end of the infusion line 2 or the drainage line 3 near the ink pad 124, thereby preventing the infusion line 2 and the drainage line 3 from extending directly under the ink stack platform 12.

[0087] Further optionally, the limiting structure 13 further includes a buckle 132 provided at the bottom of the ink stack platform 12, and the infusion pipeline 2 and the drainage pipeline 3 are clamped to the buckle 132. Specifically, the buckle 132 is provided at the bottom of the ink stack platform 12, and its setting position is spaced apart from the connection position (through hole 1211) between the ink stack platform 12 and the infusion pipeline 2 and the drainage pipeline 3, so that the infusion pipeline 2 and the drainage pipeline 3 have a smaller bending angle after extending from the ink pad 124, and are clamped by the buckle 132 after extending a distance at the bottom of the ink stack platform 12. The buckle 132 further controls the arrangement of the section of the infusion pipeline 2 and the drainage pipeline 3 close to the ink stack platform 12, which can not only control the extension direction of the infusion pipeline 2 and the drainage pipeline 3, but also reduce the possibility of interference between the infusion pipeline 2 and the drainage pipeline 3 and the lifting mechanism 13.

[0088] The first region 122 and the second region 123 are each provided with a clip 132 to respectively limit the position of the first infusion line 21, the first drainage line 31, the second infusion line 22, and the second drainage line 32. The clip 132 engages the infusion line 2 and the drainage line 3, thereby facilitating their installation. In other embodiments, the infusion line 2 and the drainage line 3 can also be pressed against the bottom of the ink stack platform 12 using a compression member. In this embodiment, the clip 132 is integrally formed with the ink stack platform 12, thereby facilitating installation of the clip 132 and ensuring stable fixation of the infusion line 2 and the drainage line 3. Of course, in other embodiments, the clip 132 can also be secured to the ink stack platform 12 by snapping, bonding, or fastener connection.

[0089] In summary, refer to Figures 3 to 9 The extension paths of the infusion line 2 and the drainage line 3 are as follows: the first infusion line 21 and the first drainage line 21 are connected to the first pipe joint 25, and then directly extend to the buckle 132 of the first area 122, and then extend to the bottom of the ink stack platform 12, and respectively control the first infusion line 21 and the first drainage line 31 to bend through the right-angle elbow 131 to connect with the ink pad 124 in the first area 122; the second infusion line 22 and the second drainage line 32 are connected to the second pipe joint 35, and then, under the limit of the first limiter 133, pass between the bottom plate 111 and the screw rod 142 to avoid the screw rod 142, and then extend to the buckle 132 of the second area 123, and extend to the bottom of the ink stack platform 12, and then respectively control the second infusion line 22 and the second drainage line 32 to bend through the right-angle elbow 131 to connect with the ink pad 124 in the second area 123. Furthermore, a second stopper 134 is provided near the first and second pipe joints 25, 35. This second stopper 134 jointly secures the infusion line 2 and the drainage line 3, enhancing the stability of the installation of the ends of the infusion line 2 and the drainage line 3 away from the ink stack platform 12. The second stopper 134, the first stopper 133, and the buckle 132 are sequentially arranged along the extension paths of the infusion line 2 and the drainage line 3. The aforementioned extension path of the infusion line 2 and the drainage line 3 is only one possible implementation of this solution. Other extension paths can be found above and will not be detailed here.

[0090] Please refer to Figures 10 to 14To facilitate cleaning of the print head, in one embodiment, a clean water box 4 and a waste liquid box 5 are further provided within the inkjet printer 100. The end of the infusion line 2 remote from the ink stack 1 is connected to the clean water box 4, and the end of the drainage line 3 remote from the ink stack 1 is connected to the waste liquid box 5. Specifically, the provision of the clean water box 4 and the waste liquid box 5 within the inkjet printer 100 eliminates the need for the infusion line 2 and the drainage line 3 to extend outside the inkjet printer 100. This facilitates the inkjet printer 100 to promptly supply cleaning fluid to the ink stack 1 and recycle waste liquid, and also improves the structural integrity of the inkjet printer 100.

[0091] Among them, the clean water box 4 and the waste liquid box 5 can be arranged in an idle position inside the inkjet printer 100, which helps to improve the structural compactness of the inkjet printer 100 and contributes to the miniaturization of the product. Therefore, the shapes of the clean water box 4 and the waste liquid box 5 can be regularly arranged, such as a rectangular parallelepiped, a cube, a cylinder or a sphere, etc.; they can also be irregularly arranged. In other embodiments, the clean water box 4 and the waste liquid box 5 may not be arranged inside the inkjet printer 100, or the clean water box 4 and the waste liquid box 5 may be arranged outside the inkjet printer 100, in which case the infusion line 2 and the drainage line 3 extend out of the inkjet printer 100 at one end away from the ink stack 1; or, the inkjet printer 100 is only provided with the clean water box 4 or only with the waste liquid box 5.

[0092] Further preferably, a clean water pump 6 is provided between the clean water box 4 and the ink stack 1, and the clean water pump 6 is used to pump the cleaning liquid in the clean water box 4 into the ink pad 124, so as to facilitate the control of the flow rate and flow of the cleaning liquid and ensure that the ink pad 124 is replenished with liquid in time.

[0093] Further preferably, a waste liquid pump 7 is provided between the waste liquid box 5 and the ink stack 1, and the waste liquid pump 7 is used to pump the waste liquid in the sewage collection tank 121 into the waste liquid pump 7, so as to facilitate the control of the flow rate and flow of the waste liquid and ensure that the waste liquid in the sewage collection tank 121 is recovered in time.

[0094] The number of the clean water pump 6 and the waste liquid pump 7 is often multiple. On the one hand, they provide sufficient power for the infusion line 2 and the drainage line 3. On the other hand, the infusion line 2 and the drainage line 3 often have multiple branches, such as the drainage line 3 having different lines to recycle waste materials of different colors or types.

The ink supply module 9 connects the ink supply cartridge 914 and the nozzle 821 of the print head 82 through an ink supply pipeline.

[0101] See Figure 1 and Figure 13 In one embodiment, the ink supply module 9 includes at least two ink supply cartridges 914. By injecting different colored inks into the at least two ink supply cartridges 914, the print head 82 can utilize different ink combinations to achieve multiple-color inkjet effects, thereby enabling the inkjet printer 100 to better process desired images or text on printed materials. In this case, the clean water tank 4 and the at least two ink supply cartridges 914 can be sequentially arranged and connected to form a single unit. The unit can then be mounted on one side of the printing platform 8 along the second direction via the support frame 92. This facilitates assembly and disassembly of the ink supply module 9 and creates a modular structure.

[0102] Further optionally, the ink stack 1 is arranged on one side of the printing table 8 along the first direction, the waste liquid box 5 is arranged on one side of the ink stack 1 along the second direction, the clean water box 4 is arranged together with the ink supply module 9 on one side of the printing table 8 along the second direction, and the waste liquid box 5 and the clean water box 4 are arranged on the same side of the inkjet printer 100, and there is an installation space on the bottom side of the printing table 8, so the clean water pump 6 and the waste liquid pump 7 are both arranged on the bottom side of the printing table 8, and are arranged on the same side of the inkjet printer 100 together with the waste liquid box 5 and the clean water box 4, which helps to reduce the flow path of the infusion pipeline 2 and the drainage pipeline 3, and the waste liquid box 5 is provided with a pipe head structure 51 on the side facing the waste liquid pump 7 to further reduce the flow path of the drainage pipeline 3.

[0103] And this structure makes the ink stack assembly and the clean water pump 6 and the waste liquid pump 7 respectively arranged on different sides of the printing table 8. In order to facilitate the arrangement of the infusion pipeline 2 and the drainage pipeline 3, refer to Figure 13 and Figure 14 The bottom of the ink stack platform 12 is provided with a plurality of spaced pipe grooves 81 , and the infusion pipeline 2 and the drainage pipeline 3 pass through the plurality of pipe grooves 81 in sequence to extend into the ink stack 1 , thereby limiting the infusion pipeline 2 and the drainage pipeline 3 .

Moreover, there is more than one arrangement method for the internal structure of the inkjet printer 100. If the arrangement method inside the inkjet printer 100 changes, the arrangement of the infusion line 2 and the drainage line 3 can also be changed accordingly. That is, this solution does not restrict the arrangement of the infusion line 2 and the drainage line 3 inside the inkjet printer 100. As long as the infusion line 2 can connect the clean water box 4 and the clean water pump 6 to the ink stack 1 in sequence, and the drainage line 3 can connect the ink stack 1 and the waste liquid pump 7 to the waste liquid box 5 in sequence, it is within the protection scope of this solution.
