[0035] When performing inkjet printing on three-dimensional substrates, in order to solve the problem of inaccurate positioning of the printing area caused by mechanical reasons of the equipment, in order to ensure that the printing area can be completely covered by the inkjet printing, such as Figure 1 As shown, the inkjet printing inkjet range is set larger than the substrate printing area to ensure that the printing area can be completely covered by ink. However, this causes the excess ink outside the printing area to contaminate the fixture holding the substrate or the printing platform. At the same time, the accumulated ink will affect the inkjet printing positioning accuracy during nozzle printing, affecting the printing quality.

[0036] Example 1

[0037] To solve the above problem, see Figure 2-8 , an embodiment of the present invention provides a printing device with an ink receiving function, the printing device comprising:

[0038] The object carrier component 1 is used for carrying the substrate 2 to be printed;

[0039] A plurality of ink receiving components 3 are installed around the substrate 2 to receive ink drops falling outside the printing area; the ink receiving components 3 include a rotating roller 32 and a rotating shaft 31, the rotating roller 32 is installed on the rotating shaft 31, and the rotating shaft 31 is used to drive the rotating roller 32 to rotate.

[0040] Specifically, the object carrier component 1 is used to fix and display the three-dimensional printing substrate 2. The object carrier component 1 can be a clamping component for clamping the printing substrate 2, or can be a flat loading platform.

[0041] The rotating roller 32 is installed on the rotating shaft 31 . The rotating shaft 31 rotates around the axis to drive the rotating roller 32 to rotate, thereby removing the ink accumulated on the rotating roller 32 .

[0042] The printing device and printing equipment with ink receiving function provided by the embodiment of the utility model receive and absorb excess ink onto the rotating roller 32 by arranging an ink receiving component 3 around the substrate 2, thereby preventing excess ink from contaminating the substrate 2 or the printing platform. At the same time, the rotating roller 32 is driven to rotate by the rotating shaft 31 to move the transmission roller that has not received ink to the ink receiving position for ink receiving, thereby preventing the ink receiving position from receiving ink for a long time, resulting in ink accumulation, and ink cannot be processed in time and falls onto the substrate 2 or the printing platform to cause pollution, while affecting the positioning accuracy during inkjet printing.

[0043] In one embodiment, the rotating shaft 31 and the rotating roller 32 are installed and fixed by keyways and fixing members.

[0044] Specifically, a keyway is provided at the same relative position of the rotating shaft 31 and the rotating roller 32. During installation, the rotating shaft 31 and the rotating roller 32 are fixedly installed by placing a fixing member in the keyway. The keyway and the fixing member enable the rotating shaft 31 and the rotating roller 32 to be quickly installed and disassembled. At the same time, according to different sizes of substrates 2, only the rotating roller 32 needs to be replaced to receive excess ink at the edge of different substrates 2.

[0045] In one embodiment, the rotating shaft 31 and the rotating roller 32 are integrated.

[0046] The integrated arrangement of the rotating shaft 31 and the rotating roller 32 can avoid the problem of loose installation between the rotating shaft 31 and the rotating roller 32 due to mechanical problems or long-term use, resulting in untimely driving, and failure to move the rotating roller 32 in time, resulting in the accumulation of ink and contamination of the carrier component 1.

[0047] In one embodiment, if Figure 2-8 The rotating shafts 31 are provided with transmission members 33 , and the transmission members 33 on adjacent rotating shafts 31 are in transmission connection so that the rotating shafts 31 can rotate synchronously.

[0048] Specifically, transmission members 33 are respectively provided at both ends of the rotating shaft 31, and the transmission members 33 on two adjacent rotating shafts 31 are connected in transmission, driving the rotating shaft 31 to rotate, so that multiple rotating shafts 31 can rotate synchronously: the transmission members 33 at both ends of a rotating shaft 31 are respectively connected to the transmission members 33 on two rotating shafts 31 at different positions, and the last rotating rotating shaft 31 drives the transmission members 33 on its two adjacent rotating shafts 31 to rotate through the rotation of the transmission member 33, and the rotating transmission member 33 drives the fixed rotating shaft 31 to rotate, thereby driving the rotating roller 32 to rotate.

[0049] In one embodiment, the printing device further comprises a driving mechanism 4, the output end of the driving mechanism 4 is connected to one of the rotating rollers 32 and drives the rotating roller to rotate.

[0050] Specifically, Figure 1 As shown, in a group of ink-receiving components 3 for removing excess ink from a printing material 2, a driving mechanism 4 is provided, and the driving mechanism 4 is connected to one of the rotating shafts 31, and is used to drive the rotating shaft 31 to rotate. The rotating rotating shaft 31 drives the remaining rotating shafts 31 to rotate through a transmission member 33 that is transmission-connected to a transmission member 33 on the rotating shaft 31.

[0051] This embodiment can control all the rotating shafts 31 in the printing device to rotate by setting a driving mechanism 4, so as to remove excess ink from the edge of the substrate 2. It has a simple structure, convenient operation and control, and can reduce the space occupied by the printing device.

[0052] In one embodiment, the printing device further includes a plurality of driving mechanisms 4, and one of the driving mechanisms 4 is connected to the rotating shaft 31 of the ink receiving component 3 for driving the rotating shaft 31 to rotate.

[0053] Specifically, when the number of the driving mechanisms 4 is the same as the number of the ink receiving components 3, a driving mechanism 4 is set to control the rotation of a rotating shaft 31 to achieve individual control of each ink receiving component 3. When the nozzle is away from an ink receiving component 3, the ink receiving component 3 is controlled not to rotate, and the ink receiving components 3 at various positions can be accurately controlled in real time according to printing requirements.

[0054] In one embodiment, the printing device is provided with a plurality of driving mechanisms 4 , and one of the driving mechanisms 4 is connected to one of the rotating shafts 31 , and is used to drive and control the rotating shafts 31 corresponding to the plurality of ink receiving components 3 to rotate.

[0055] Specifically, according to the direction of the nozzle during printing, the ink receiving components 3 are grouped, and one of the rotating shafts 31 of the ink receiving components 3 in one group is connected to a driving mechanism 4, and the driving mechanism 4 drives the connected rotating shafts 31 to rotate, and the rotating shafts 31 drive the adjacent rotating shafts 31 to rotate through the transmission member 33. The movement of the ink receiving components 3 at different positions can be controlled in real time according to the direction of nozzle printing, and the number of driving mechanisms 4 can be reduced while also achieving precise control of the ink receiving components 3.

[0056] In one embodiment, the printing device further comprises a supporting bracket for fixedly mounting a plurality of groups of the ink receiving components 3 .

[0057] Specifically, the ink receiving component 3 is structurally separated from the carrier component 1, so that when printing, the substrates 2 of different sizes can be quickly connected to ink. At the same time, there is a gap between the ink receiving component 3 and the carrier component 1, which can prevent the ink received by the ink receiving component 3 from contaminating the carrier component 1.

[0058] A supporting bracket is provided for supporting the ink receiving component 3, which can ensure that the ink receiving component 3 can be suspended on the object-carrying component 1 without being connected with the object-carrying component 1, and at the same time ensure that the suspended setting can enable the rotating shaft 31 to smoothly drive the rotating shaft to rotate.

[0059] In one embodiment, a replacement part is installed on the surface of the rotating roller 32 for receiving ink.

[0060] Specifically, in order to absorb the fallen ink in time and ensure the ink receiving effect, a replacement part made of a material that can quickly absorb ink is installed on the rotating roller 32. When the replacement part absorbs a certain amount of ink, it can be replaced in time.

[0061] Avoid using the rotating roller 32 to absorb ink directly, which will cause the rotating roller 32 to need to be replaced, which is time-consuming and labor-intensive, and the cost of the rotating roller 32 is high.

[0062] The replacement part is preferably paper, ink-absorbent plastic or the like.

[0063] In one embodiment, there is a certain gap between the rotating roller 32 and the printing material 2 .

[0064] Specifically, the rotating roller 32 is close to the substrate 2 but does not contact the substrate 2, so as to prevent the ink on the rotating roller 32 from contaminating the substrate 2, while ensuring that the rotating roller 32 can rotate normally.

[0065] Preferably, the gap between the rotating roller 32 and the three-dimensional substrate 2 is preferably 0.5 mm-3 mm to prevent ink from falling onto the carrier component 1.

[0066] In one embodiment, if Figure 5As shown, the rotating roller 32 is a cylindrical structure.

[0067] As shown in the figure, the rotating roller 32 is configured as a cylindrical structure. When the rotating roller 32 is controlled to rotate, the rotating roller 32 can be configured to rotate at a uniform speed to timely receive the excess ink that falls.

[0068] In one embodiment, if Figure 6 , Figure 7 As shown, the rotating roller 32 is a regular prismatic structure, and the rotating shaft 31 drives the driving roller to rotate a preset angle.

[0069] Specifically, Figure 6 , Figure 7 As shown, the prism shape is preferably a triangular prism and a hexagonal prism, and one edge of the prism is arranged closest to the substrate 2. The surface of the prism that receives the ink is inclined, and when receiving the ink, the ink can be quickly absorbed. At the same time, the setting of the inclined surface can delay the ink from falling down on the surface of the rotating roller 32.

[0070] like Figure 7 As shown, when the rotating roller 32 is a triangular prism, controlling the rotating roller 32 to rotate 120° at a time can make the next edge closest to the substrate 2, and the surface receiving the ink has the smallest inclination angle, thereby improving the ink receiving efficiency. When the ink accumulates on the surface to a certain extent, the rotating shaft 31 is controlled to drive the rotating roller 32 to rotate 120°.

[0071] Similarly, if Figure 6 As shown, when the rotating roller 32 is in the shape of a hexagonal prism, controlling the rotating roller 32 to rotate 60° at a time can make the next edge closest to the substrate 2, and the inclination angle of the surface receiving ink is the smallest, thereby improving the ink receiving efficiency. Figure 8 As shown, when the ink accumulates on the surface to a certain extent, the rotating shaft 31 is controlled to drive the rotating roller 32 to rotate 60°.

[0072] The printing device and printing equipment with ink receiving function provided by the embodiment of the utility model receive and absorb excess ink onto the rotating roller 32 by arranging an ink receiving component 3 around the substrate 2, thereby preventing excess ink from contaminating the substrate 2 or the printing platform. At the same time, the rotating roller 32 is driven to rotate by the rotating shaft 31 to move the transmission roller that has not received ink to the ink receiving position for ink receiving, thereby preventing the ink receiving position from receiving ink for a long time, resulting in ink accumulation, and ink cannot be processed in time and falls onto the substrate 2 or the printing platform to cause pollution, while affecting the positioning accuracy during inkjet printing.

[0077] The inkjet printing assembly 5 is installed above the working platform 6 and is used for performing inkjet printing on the three-dimensional printing material 2 on the carrier assembly 1 .

[0078] In one embodiment, if Fig. 9 As shown, the printing assembly is movably installed above the working platform and is used for performing inkjet printing on the three-dimensional substrate on the printing device during movement.

[0079] Specifically, the inkjet printing assembly performs scanning and printing along the X direction, and steps along the Y direction to perform inkjet printing on the next printing area.

[0080] In one embodiment, if Fig. 9 As shown, the printing assembly is fixedly installed above the working platform. The movement of the working platform drives the printing device to move, and the printing assembly performs inkjet printing on the three-dimensional substrate moved below.

[0081] Specifically, the inkjet printing assembly performs scanning and printing along the X direction, controls the working platform to move and step in the Y direction, drives the printing device and the substrate to move relative to the inkjet printing assembly in the Y direction, and performs inkjet printing on the next printing area.

[0082] The printing device with ink receiving function provided in the present embodiment includes the printing device described in Example 1, and an ink receiving component is arranged around the substrate to receive and absorb excess ink onto the rotating roller, thereby preventing excess ink from contaminating the substrate or the printing platform. At the same time, the rotating roller is driven to rotate by the rotating shaft to move the transmission roller that has not received ink to the ink receiving position for ink receiving, thereby preventing the ink receiving position from receiving ink for a long time, resulting in ink accumulation, and ink falling onto the substrate or the printing platform to cause pollution due to failure to handle it in time, thereby preventing ink accumulation on the printing device or the clamping device, resulting in subsequent positioning printing of the substrate.
