[0042] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] In a first aspect, please refer to Figure 1 and Figure 2 . An ink suction device 100 is provided in an embodiment of the present application. The ink suction device 100 includes a mounting frame 1, a translation assembly 2, an ink suction assembly 3, a light shielding assembly 4, and a driving assembly 5. The ink suction assembly 3 and the light shielding assembly 4 are mounted on the mounting frame 1 through the translation assembly 2. The driving assembly 5 is used to drive the ink suction assembly 3 and the light shielding assembly 4 to translate relative to the mounting frame 1. The ink suction assembly 3 is used to suck the ink of the print head, and the light shielding assembly 4 is used to reduce the light irradiating the print head.

[0044] It should be noted that in the drawings of the embodiments of the present application, the dashed arrow indicates that the arrow points into the paper, and the solid arrow indicates that the arrow points out of the paper or is parallel to the paper surface.

[0045] For the above-mentioned mounting frame 1, please refer to Figure 1 and Figure 2 . The mounting frame 1 is in a frame shape and is adapted to the translation assembly 2 to mount the translation assembly 2 and shield and protect the translation assembly 2.

[0046] For the above-mentioned translation assembly 2, please refer to Figure 3 . The translation assembly 2 includes a fixing member 21 and a first sliding member 22. The fixing member 21 is disposed on the mounting frame 1, and the first sliding member 22 is slidably disposed on the fixing member 21 along a first direction X. Specifically, the fixing member 21 is provided with a first guide rail 211, and the first sliding member 22 is provided with a first slider 221. The first guide rail 211 is slidably connected to the first slider 221, and the extending direction of the first guide rail 211 is parallel to the first direction X, so that the first sliding member 22 is slidably disposed on the fixing member 21 along the first direction X. Optionally, the fixing member 21 is a wall panel, and the first sliding member 22 is in a flat plate shape.

[0047] Among them, please refer to Figure 3 . The translation assembly 2 can be provided with two groups. The fixing members 21 of the two groups of translation assemblies 2 are both disposed on the mounting frame 1 and are spaced apart. The first sliding members 22 of the two groups of translation assemblies 2 are respectively connected to both ends of the ink suction assembly 3 and the light shielding assembly 4 to improve the stability of the sliding connection between the ink suction assembly 3 and the light shielding assembly 4 and the mounting frame 1.

[0048] For the above-mentioned ink suction assembly 3, please refer to Figures 2 to 4, the ink absorption assembly 3 is arranged on the first sliding member 22, and the ink absorption assembly 3 is used for sucking the ink on the side of the printing head facing the second direction Y. Specifically, the ink absorption assembly 3 includes a first cross beam 31 and a plurality of suction nozzles 32; the first cross beam 31 extends along the third direction Z; the plurality of suction nozzles 32 are arranged on the first cross beam 31 at intervals along the third direction Z, and the suction nozzles 32 are arranged on the side of the first cross beam 31 facing away from the second direction Y. The opening of the suction nozzle 32 can be strip-shaped to increase the suction area of the printing head. The suction nozzle 32 can be connected to a negative pressure device, such as a vacuum machine, through a pipeline to achieve negative pressure suction of ink.

[0049] In the embodiment of the present application, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0050] Since the plurality of suction nozzles 32 are arranged at intervals along the third direction Z, the ink absorption assembly 3 can move translationally along the first direction X relative to the mounting frame 1 with the first sliding member 22, so that the ink on the side of the printing head facing the second direction Y can be sucked, reducing the residual amount of ink on the printing head. When directly wiping the ink on the printing head through the ink wiping device, since the ink usually has a high viscosity, it is difficult to wipe off the ink. However, by reducing the residual amount of ink on the printing head through the ink absorption assembly 3, the problem that the ink on the printing head is difficult to remove can be improved, and even the ink on the printing head can be completely sucked by the ink absorption assembly 3.

[0051] Please refer to again Figure 4 and Figure 5 , the ink absorption assembly 3 further includes a diversion member 33. One end of the diversion member 33 is connected to the side of the first cross beam 31 facing the second direction Y. A first diversion groove 331 is formed on the side of the diversion member 33 facing away from the second direction Y, and the end of the first diversion groove 331 extends to the side of the light shielding assembly 4 facing the second direction Y; a second diversion groove 311 and a first diversion hole 312 are arranged on the side of the first cross beam 31 facing away from the second direction Y. The second diversion groove 311 extends along the third direction Z, the first diversion hole 312 is communicated with the second diversion groove 311, the first diversion hole 312 penetrates to the side of the first cross beam 31 facing the second direction Y, and a part of the first diversion groove 331 extends to the side of the first diversion hole 312 facing the second direction Y. In the embodiment of the present application, the second direction Y is the gravity direction. The ink on the first cross beam 31 can flow and gather in the second diversion groove 311, then drip into the first diversion groove 331 through the first diversion hole 312, and finally flow to the lower part of the light shielding assembly 4 through the first diversion groove 331 and drip, so that the dripping ink avoids the pipeline connected to the suction nozzle 32, improving the problem that the ink drips and adheres to the pipeline.

[0052] Among them, the number of the second diversion grooves 311 and the first diversion holes 312 can be multiple, and at least one second diversion groove 311 corresponds to at least one first diversion hole 312; the number of the diversion members 33 can be multiple, the number of the first diversion grooves 331 of the diversion member 33 can be multiple, and at least one first diversion groove 331 corresponds to at least one first diversion hole 312. Optionally, the first cross beam 31 is provided with two second diversion grooves 311, and the two second diversion grooves 311 are arranged on both sides of the suction nozzle 32 along the first direction X.

[0053] Please refer to Figure 5 and Figure 6 , the ink suction assembly 3 and the light shielding assembly 4 are arranged in sequence along the first direction X, the light shielding assembly 4 is provided with a diversion plate 412, and at least a part of the diversion plate 412 is located on the side of the ink suction assembly 3 facing away from the second direction Y. Specifically, please refer to Figure 5 and Figure 6 , a diversion plate 412 is arranged on the side of the liquid collecting tray 41 adjacent to the ink suction assembly 3, and the end of the diversion plate 412 is located on the side of the ink suction assembly 3 facing away from the second direction Y. Please refer to Figure 4 again, a third diversion groove 313 and a second diversion hole 314 are arranged on the side of the first cross beam 31 facing away from the second direction Y, the second diversion hole 314 is communicated with the third diversion groove 313, and the second diversion hole 314 penetrates through to the side of the first cross beam 31 facing the second direction Y; the ink suction assembly 3 and the light shielding assembly 4 are arranged in sequence along the first direction X, the diversion plate 412 extends along the opposite direction of the first direction X and the second direction Y, and when observed along the second direction Y, the projection of the end of the diversion plate 412 facing the second direction Y at least partially coincides with the third diversion groove 313. In the embodiment of the present application, the second direction Y is the gravity direction, the ink suction assembly 3 and the light shielding assembly 4 are arranged in sequence along the first direction X, and the projection of the end of the diversion plate 412 facing the second direction Y at least partially coincides with the third diversion groove 313, so the diversion plate 412 is inclined, and the diversion plate 412 extends simultaneously along the opposite direction of the first direction X and downward. That is to say, the lower end of the diversion plate 412 is located above the third diversion groove 313, so the ink on the diversion plate 412 will flow to the lower end of the diversion plate 412 and drip into the third diversion groove 313, and then drip into the first diversion groove 331 through the second diversion hole 314, and finally flow to the lower part of the light shielding assembly 4 through the first diversion groove 331 and drip, so that the dripping ink avoids the pipeline connected to the suction nozzle 32, and improves the problem that the ink drips and adheres to the pipeline.

[0054] For the above-mentioned light shielding assembly 4, please refer to Figure 2 and Figure 3 , the light shielding assembly 4 is arranged on the first sliding member 22, and the light shielding assembly 4 is used to reduce the light irradiation on the print head. Specifically, please refer to Figure 5 and Figure 6, the light-shielding component 4 includes a liquid collecting tray 41 and a light-absorbing member 42; the liquid collecting tray 41 is disposed on the first sliding member 22, and a liquid leakage hole 411 is provided at the bottom of the liquid collecting tray 41; the light-absorbing member 42 is disposed in the liquid collecting tray 41, and the light-absorbing member 42 is used to reduce the light reflected above the light-shielding component 4 to the printing head. When the light-shielding component 4 is working, at least a part of the light-shielding component 4 is located on one side of the printing head facing the second direction Y, and a relatively small gap can be provided between the light-shielding component 4 and the printing head, so as to reduce the light in the environment from irradiating the printing head; and the light-absorbing member 42 is disposed in the liquid collecting tray 41. When the curing lamp of the printing head is abnormally turned on or forgotten to be turned off, the light-absorbing member 42 can absorb the light of the curing lamp and reduce the light of the curing lamp from being reflected and irradiating the printing head. By reducing the light of the ambient light and the curing lamp from irradiating the printing head, the problems of the ink curing in the printing head and the difficulty in removing the cured ink are improved. Optionally, the curing lamp is a UV lamp.

[0055] Wherein, the liquid collecting tray 41 is further used to receive the ink dripped from the printing head and leak out through the liquid leakage hole 411. Among them, please refer to Figure 5 , the light-shielding component 4 further includes a pipeline groove 43, the pipeline groove 43 avoids the position below the liquid leakage hole 411, and the pipeline groove 43 is used to accommodate the pipeline connected to the suction nozzle 32, so as to improve the problem of the ink dripping and adhering to the pipeline. Optionally, the number of the liquid leakage holes 411 is two, and the shape of the liquid leakage hole 411 is rectangular.

[0056] For the above light-absorbing member 42, please refer to Figure 7 , the light-absorbing member 42 includes a plurality of light-blocking strips 421, the plurality of light-blocking strips 421 are arranged at intervals along the first direction X, the light-blocking strip 421 includes a first wall 4211 and a second wall 4212, the included angle between the first wall 4211 and the plane perpendicular to the first direction X is 45 degrees, the second wall 4212 is arranged along the first direction X with the first wall 4211, one end of the second wall 4212 is connected to one end of the first wall 4211, and the included angle between the second wall 4212 and the first wall 4211 is 90 degrees. When the light of the curing lamp irradiates the first wall 4211 along the second direction Y, the light will first be reflected to the first wall 4211 of another adjacent light-blocking strip 421, then reflected to the second wall 4212 of this light-blocking strip 421, and then reflected to the second wall 4212 of the previous light-blocking strip 421, and finally reflected to the liquid collecting tray 41. The light reflected to the liquid collecting tray 41 can still be reflected to the printing head along the reverse direction of the above light path after being reflected by the liquid collecting tray 41, but the light intensity of the light will be greatly attenuated after multiple reflections, so as to reduce the light intensity of the light of the curing lamp reflected to the printing head.

[0057] Wherein, the light-absorbing member 42 can be made of a light-absorbing material or be provided with a light-absorbing material on the surface to further reduce the light intensity of the light of the curing lamp reflected to the printing head.

[0058] Among them, when observing along the second direction Y, two adjacent first walls 4211 partially overlap, and / or two adjacent second walls 4212 partially overlap. The partial overlap of two adjacent first walls 4211 or the partial overlap of two adjacent second walls 4212 can reduce the situation where the light of the curing lamp passes through the gap between two adjacent light-shielding strips 421 and irradiates the liquid collecting tray 41, and then passes through the gap between two adjacent light-shielding strips 421 again after being reflected by the liquid collecting tray 41 and irradiates the printing nozzle, thus improving the problem of aggravated ink curing of the printing nozzle caused by light leakage of the light-absorbing member 42.

[0059] For the above driving assembly 5, please refer to Figure 2 and Figure 3 , the driving assembly 5 is arranged on the fixing member 21, and the driving assembly 5 is used to drive the first sliding member 22 to slide relative to the fixing member 21 along the first direction X. Specifically, please refer to Figure 3 and Figure 8 , the driving assembly 5 includes a pulley 51, a transmission belt 52, a connecting member 53, a driving member 54 and a sensor 55; the pulley 51 is rotatably arranged on the fixing member 21; the transmission belt 52 is sleeved on a plurality of pulleys 51; the connecting member 53 is arranged on the first sliding member 22, the connecting member 53 is connected to the transmission belt 52, and the connecting member 53 is provided with a baffle 531; the driving member 54 is arranged on the fixing member 21, and the driving member 54 is in transmission connection with at least one pulley 51; the sensor 55 is arranged on the fixing member 21, and the sensor 55 is used to be triggered when the baffle 531 passes by. Optionally, the number of pulleys 51 is two.

[0060] When the driving member 54 works, it drives at least one pulley 51 to rotate. Since the transmission belt 52 is sleeved on a plurality of pulleys 51, the pulleys 51 sleeved with the transmission belt 52 all rotate, and the transmission belt 52 also moves along its own extending direction. And the connecting member 53 connects the first sliding member 22 with the transmission belt 52, then drives the first sliding member 22 to move. It can be understood that the part of the transmission belt 52 stretched between the two pulleys 51 is straight. By making this part parallel to the first direction X and connecting it with the connecting member 53, the first sliding member 22 can be driven to slide relative to the fixing member 21 along the first direction X. Optionally, the driving member 54 is a servo motor.

[0061] Among them, please refer to Figure 3 and Figure 8 , two sets of driving assemblies 5 can be arranged. The two sets of driving assemblies 5 are respectively used to drive two sets of translation assemblies 2, improving the stability of the driving assembly 5 to drive the first sliding member 22 to slide relative to the fixing member 21. Among them, the two sets of driving assemblies 5 can share a driving member 54, please refer to Figure 3The driving member 54 includes a long rotating shaft 541, and both ends of the long rotating shaft 541 are respectively connected to the pulleys 51 of the two groups of driving components 5. The long rotating shaft 541 is connected to the output shaft (not shown) of the driving member 54, so that one driving member 54 can drive the transmission belts 52 of the two groups of driving components 5 to move synchronously, which can not only reduce the number of driving members 54, but also improve the synchronization of the movement of the transmission belts 52 of the two groups of driving components 5.

[0062] When the sensor 55 is triggered, an electrical signal can be sent to the driving member 54 to stop the driving member 54, thereby limiting the travel of the connecting member 53, the ink absorbing assembly 3 and the light shielding assembly 4 relative to the mounting frame 1 along the first direction X, and improving the problem of the translation assembly 2 and the driving assembly 5 being damaged due to exceeding the working travel. It can be understood that the number of sensors 55 is usually two, and the two sensors 55 are respectively triggered by the baffle 531 when the connecting member 53 moves to the two ends of the working travel; the number of sensors 55 can also be one, in which case the connecting member 53 needs to be provided with two baffles 531, and the two baffles 531 respectively trigger the sensor 55 when the connecting member 53 moves to the two ends of the working travel. Optionally, the sensor 55 is a photoelectric switch, and the baffle 531 blocks the light emitted by the photoelectric switch to trigger the photoelectric switch.

[0063] In some embodiments, see Figure 3 The translation assembly 2 further includes a second sliding member 23 and an adjusting structure 24; the second sliding member 23 can be slidably disposed on the first sliding member 22 along the first direction X, and the ink absorbing assembly 3 is disposed on the second sliding member 23; the adjusting structure 24 can be slidably disposed on the fixing member 21 along the first direction X, and the adjusting structure 24 is connected to the second sliding member 23, and the adjusting structure 24 is used to adjust the position of the second sliding member 23 relative to the first sliding member 22 along the second direction Y. For details, please refer to Figure 9 The first sliding member 22 is provided with a second guide rail 222, and the second sliding member 23 is provided with a second slider 231. The second guide rail 222 is slidably connected to the second slider 231. The extension direction of the second guide rail 222 is parallel to the second direction Y, so that the second sliding member 23 can be slidably arranged on the first sliding member 22 along the second direction Y.

[0064] The adjustment structure 24 adjusts the position of the second sliding member 23 relative to the first sliding member 22 along the second direction Y, thereby adjusting the pressure between the ink absorption component 3 and the print nozzle, or adjusting the depth of the ink absorption component 3 entering the print nozzle along the second direction Y, thereby improving the problem of damage to the print nozzle and the suction nozzle 32 caused by the hard contact between the ink absorption component 3 and the print nozzle, and at the same time improving the problem of the suction nozzle 32 not contacting the print nozzle due to assembly error or wear, thereby improving the poor ink absorption effect of the suction nozzle 32.

[0065] For the above mentioned adjustment structure 24, see Figure 9, the adjusting structure 24 includes a support rod 241, a support base 242 and an adjusting member 243; the fixing member 21 is provided with a sliding groove 212 extending along the first direction X, and one end of the support rod 241 is slidably disposed in the sliding groove 212; the support base 242 is disposed on the support rod 241, and the support base 242 is slidably connected to the second sliding member 23 along the second direction Y. The support base 242 includes an abutting portion 2421, and at least a part of the abutting portion 2421 is disposed on the side of the second sliding member 23 facing the second direction Y; the adjusting member 243 is threadedly connected to the abutting portion 2421, and the other end abuts against the second sliding member 23. Specifically, the support base 242 is provided with a through hole 2422 penetrating along the third direction Z, and the through hole 2422 extends along the first direction X. A screw (not shown) passes through the through hole 2422 and is connected to the second sliding member 23 to slidably connect the support base 242 to the second sliding member 23 along the second direction Y; the support base 242 is fixedly connected to the support rod 241, for example, by screws or bolts. In the embodiment of the present application, the second direction Y is the direction of gravity, and the second sliding member 23 abuts against the adjusting member 243 under the action of gravity. By rotating the adjusting member 243, the position of the second sliding member 23 relative to the first sliding member 22 along the second direction Y can be adjusted. Optionally, the adjusting member 243 is a stud.

[0066] Wherein, after the position adjustment of the second sliding member 23 relative to the first sliding member 22 along the second direction Y is completed, the screw passing through the through hole 2422 and connected to the second sliding member 23 can also be tightened, so as to fix the position of the second sliding member 23 relative to the first sliding member 22 along the second direction Y, which can improve the problem of the second sliding member 23 moving upward, and can also share the pressure of the second sliding member 23 on the adjusting member 243, reducing the thread damage of the threaded connection between the adjusting member 243 and the abutting portion 2421.

[0067] In some other embodiments, the adjusting member 243 can be replaced with an elastic member, and the elastic member is supported between the abutting portion 2421 and the second sliding member 23, so that the ink absorption assembly 3 contacts the printing head through the elastic acting force. The elastic member can be a straight spring.

[0068] When the first sliding member 22 slides relative to the fixing member 21 along the first direction X, the end of the support rod 241 slides in the sliding groove 212, so that the first sliding member 22 and the adjusting structure 24 move synchronously relative to the fixing member 21 along the first direction X, and the adjusting structure 24 can continuously support the second sliding member 23.

[0069] Wherein, the number of the fixing members 21 can be two, and both ends of the support rod 241 are respectively disposed in the two sliding grooves 212 of the two fixing members 21. Bearings can be provided at the ends of the support rod 241, and the support rod 241 is rollingly connected to the sliding groove 212 through the bearings to reduce friction.

[0070] In some embodiments, please refer toFigure 1 and Figure 2 Further, the ink suction device 100 further includes a liquid collecting tank 6. The liquid collecting tank 6 is disposed on the mounting bracket 1, and the liquid collecting tank 6 is located on the side of the ink suction assembly 3 and the light shielding assembly 4 facing the second direction Y. The liquid collecting tank 6 is used for receiving the ink dripping from the diversion member 33 and the liquid collecting tray 41. The liquid collecting tank 6 is in a funnel shape and is connected with a pipe at the bottom to discharge the received ink.

[0071] In a second aspect, an embodiment of the present application provides a printer (not shown), and the printer includes the ink suction device 100 as described in any one of the above. The printer has the structural features and beneficial effects of the ink suction device 100, which will not be elaborated here.

[0072] In the ink suction device 100 and the printer according to the embodiments of the present application, the ink suction assembly 3 is used for sucking the ink of the print head, reducing the residual amount of the ink on the print head; the light shielding assembly 4 is used for reducing the light irradiation on the print head, reducing the curing of the ink on the print head, thereby improving the problem that the ink on the print head is difficult to remove. The diversion member 33 enables the dripping ink to avoid the pipe connected to the suction nozzle 32, and the pipe connected to the suction nozzle 32 avoids the position below the liquid leakage hole 411, improving the problem that the ink drips and adheres to the pipe. The adjusting structure 24 adjusts the position of the second sliding member 23 relative to the first sliding member 22 along the second direction Y, improving the problem that the hard contact between the ink suction assembly 3 and the print head causes damage to the print head and the suction nozzle 32, and at the same time improving the problem that the suction nozzle 32 does not contact the print head due to assembly error or wear, thereby resulting in poor ink suction effect of the suction nozzle 32.
