At the same time, the digital printing inkjet device also has the characteristics of energy saving and environmental protection, and has become one of the important devices in the field of textile printing.

[0003] Currently, ink or pigment is generally supplied through an ink cartridge, but the digital printing inkjet device of the prior art has the following disadvantages during use:

[0004] On the one hand, only a fixed filter screen structure is set in the ink cartridge to filter impurities in the ink, but the filter screen cannot move up and down, and when too many impurities are intercepted on the surface at the same time, it is easy to cause the problem of low filtration efficiency;

[0005] On the other hand, the discharge volume during ink supply is fixed and cannot be adjusted according to the actual use situation, so the scope of use is limited. Therefore, we have designed a digital printing inkjet device to solve the above problems. Summary of the Invention

[0006] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to provide a digital printing inkjet device.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A digital printing inkjet device includes an ink cartridge. A threaded connection ink outlet pipe is fixed at the outlet at the right edge of the bottom end of the ink cartridge. A motor is fixedly connected to the center of the top end of the ink cartridge. The output shaft of the motor extends into the ink cartridge and is fixedly connected with a stirring shaft. The bottom end of the stirring shaft is rotatably connected to the middle of the inner bottom wall of the ink cartridge. A plurality of stirring blades are fixedly connected to the outer side of the stirring shaft. A spline bar is fixedly connected to the outer side of the stirring shaft. The same spline sleeve is movably sleeved on the outer sides of the spline bar and the stirring shaft. The spline sleeve is rotatably connected to the middle of the filter screen. The filter screen slides in the ink cartridge. A scraping plate is movably attached to the top of the filter screen. One end of the scraping plate is fixedly connected to the outer side of the spline sleeve. Two symmetrically arranged electric heating plates are fixedly connected to the inner wall of the ink cartridge above the filter screen;

[0009] An up-and-down driving structure is installed at the bottom end of the filter net and is connected to the inner wall of the ink cartridge. The up-and-down driving structure can enable the spline sleeve to rotate and enable the filter net to reciprocate up and down in the ink cartridge.

[0010] An ink output amount adjusting structure is installed on the threaded ink output pipe and is connected to the ink cartridge. The ink output amount adjusting structure is used to adjust the ink supply amount of the threaded ink output pipe.

[0011] Preferably, a refilling pipe is fixed at the feeding port on the right edge of the top end of the ink cartridge, and a sealing cover is threadedly connected to the top end of the refilling pipe.

[0012] Preferably, the up-and-down driving structure includes a turntable fixedly connected to the outside of the spline sleeve. The turntable is located below the filter net. A roller is rotatably connected to the bottom edge of the turntable, and the bottom of the roller is movably lapped on the top inclined surface of the inclined disk. Both ends of the inclined disk are fixedly connected to the inside of the ink cartridge through connecting rods.

[0013] Preferably, movable rods with a square cross-sectional structure are respectively movably inserted on the two connecting rods. Springs are movably sleeved on the outside of the movable rods. One ends of the two springs are fixedly connected to the bottom end of the filter net, and one ends of the two springs are fixedly connected to the top ends of the connecting rods.

[0014] Preferably, the ink output amount adjusting structure includes a funnel-shaped channel arranged inside the threaded ink output pipe. A piston block is movably installed in the funnel-shaped channel. A reverse L-shaped moving rod is fixedly connected to the top end of the piston block.

[0015] Preferably, a hand-tightening screw rod is threadedly connected to the bottom end of the ink cartridge, and the top end of the hand-tightening screw rod is rotatably connected to the reverse L-shaped moving rod.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, by arranging the up-and-down driving structure, while the stirring shaft and multiple stirring blades are driven by the motor to rotate, the cooperation of the two electric heating plates can facilitate the stirring and heating of the ink, avoiding poor printing effects caused by ink solidification.

[0017] Secondly, when the stirring shaft rotates, the spline sleeve can be driven to rotate through the spline strip, so that the scraper scrapes the impurities intercepted on the surface of the filter net, so as to achieve the purpose of preventing the surface of the filter net from being blocked by impurities. In addition, the turntable drives the roller to rotate along the top inclined surface of the inclined disk, and with the cooperation of multiple components, the filter net can move up and down, thereby greatly improving the filtering efficiency of the filter net.

[0018] Furthermore, by setting up an ink output adjustment structure, the hand-tightened screw can be manually rotated, so that the inverted L-shaped moving rod can drive the piston block to move up or down. When the piston block moves up, the gap becomes smaller, thereby reducing the flow rate. Otherwise, the flow rate becomes larger, so that the ink supply can be adjusted according to different printing conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0024] Example

[0025] On the one hand, the impurities in the ink are filtered only by setting a fixed filter screen 6 structure in the ink cartridge 1, but the filter screen 6 cannot move up and down, and when too many impurities are intercepted on the surface, it is easy to cause the problem of low filtering efficiency;

[0026] Secondly, the ink supply volume is fixed and cannot be adjusted according to actual usage, so the scope of use is limited.

[0027] For this purpose, refer to Figures 1-3, a digital printing inkjet device, including an ink cartridge 1. A liquid outlet pipe 2 is fixedly connected to the right edge of the bottom end of the ink cartridge 1 by means of a screw connection. A motor 4 is fixedly connected to the center of the top end of the ink cartridge 1. The output shaft of the motor 4 extends into the ink cartridge 1 and is fixedly connected with a stirring shaft 41. The bottom end of the stirring shaft 41 is rotatably connected to the middle of the inner bottom wall of the ink cartridge 1. A plurality of stirring blades 42 are fixedly connected to the outer side of the stirring shaft 41. A spline bar 43 is fixedly connected to the outer side of the stirring shaft 41. A spline sleeve 44 is movably sleeved on the outer sides of the spline bar 43 and the stirring shaft 41. The spline sleeve 44 is rotatably connected to the middle of a filter screen 6. The filter screen 6 slides in the ink cartridge 1. A scraping plate 45 is movably attached to the top of the filter screen 6. One end of the scraping plate 45 is fixedly connected to the outer side of the spline sleeve 44. Above the filter screen 6, there are two symmetrically arranged electric heating plates 5 fixedly connected to the inner wall of the ink cartridge 1;

[0028] An up-and-down guiding structure 7 is installed at the bottom end of the filter screen 6 and is connected to the inner wall of the ink cartridge 1. The up-and-down guiding structure 7 can enable the spline sleeve 44 to rotate and enable the filter screen 6 to move up and down reciprocally in the ink cartridge 1;

[0029] An ink output amount adjusting structure 8 is installed on the liquid outlet pipe 2 connected by means of a screw connection and is connected to the ink cartridge 1. The ink output amount adjusting structure 8 is used to adjust the size of the ink supply amount of the liquid outlet pipe 2 connected by means of a screw connection.

[0030] In this embodiment, a refilling pipe 3 is fixedly connected to the feeding port at the right edge of the top end of the ink cartridge 1. A sealing cover 31 is threadedly connected to the top end of the refilling pipe 3.

[0031] In this embodiment, in order to enable the stirring shaft 41 to rotate and to promote the filter screen 6 to move up and down, the up-and-down guiding structure 7 is provided. The up-and-down guiding structure 7 includes a turntable 71 fixedly connected to the outer side of the spline sleeve 44. The turntable 71 is located below the filter screen 6. A roller 72 is rotatably connected to the bottom edge of the turntable 71. The bottom of the roller 72 is movably lapped on the top inclined surface of an inclined disk 73. The two ends of the inclined disk 73 are respectively fixedly connected to the inner side of the ink cartridge 1 by connecting rods 74. Square cross-sectioned movable rods 75 are respectively movably inserted on the two connecting rods 74. Springs 76 are movably sleeved on the outer sides of the movable rods 75. One ends of the two springs 76 are fixedly connected to the bottom end of the filter screen 6, and one ends of the two springs 76 are fixedly connected to the top ends of the connecting rods 74.

[0032] Among them, when the turntable 71 rotates, it drives the roller 72 to rotate along the top inclined surface of the inclined disk 73. With the cooperation of the springs 76, the filter screen 6 can move up and down, thereby greatly improving the filtering efficiency of the filter screen 6. A circular hole larger than the outer diameter of the spline sleeve 44 is opened at the center of the inclined disk 73. The inclined disk 73 is sleeved on the outer sides of the spline bar 43 and the stirring shaft 41 through this circular hole, so as not to affect the normal driving of the stirring shaft to rotate the spline bar 43.

[0033] In this embodiment, in order to enable the ink supply volume to be adjusted according to the actual situation, an ink output volume adjustment structure 8 is provided, which includes a funnel-shaped channel provided inside the ink outlet pipe 2 connected by threads. A piston block 81 is movably installed in the funnel-shaped channel. The top end of the piston block 81 is fixedly connected to an inverted L-shaped moving rod 82. The top end of the inverted L-shaped moving rod 82 is fixedly connected to a slider 83 with a convex cross-sectional structure. The slider 83 is slidably connected to a chute provided on the inner wall of the ink cartridge 1. The bottom end of the ink cartridge 1 is connected by threads to a hand-tightening screw rod 84. The top end of the hand-tightening screw rod 84 is rotatably connected to the inverted L-shaped moving rod 82.

[0034] Among them, the piston block 81 has a conical structure. When the piston block 81 moves upward, the gap becomes smaller, so the flow rate becomes smaller. On the contrary, the flow rate becomes larger, so as to adjust the ink supply volume according to different printing situations.

[0035] Embodiment: When using this digital printing inkjet device, the sealing cover 31 can be loosened, and ink can be filled into the ink cartridge 1, and the sealing cover 31 can be locked. Secondly, a supply pipe is threadedly connected to the ink outlet pipe 2 connected by threads. By starting the motor 4 and energizing the two electric heating plates 5, while the stirring shaft 41 and the multiple stirring blades 42 are rotating, the cooperation of the two electric heating plates 5 can facilitate the stirring and heating of the ink to prevent the ink from solidifying and resulting in a poor printing effect. Secondly, when the stirring shaft 41 rotates, the spline sleeve 44 can be driven to rotate through the spline bar 43, so that the scraper 45 scrapes the impurities intercepted on the surface of the filter net 6, so as to prevent the impurities from blocking the surface of the filter net 6. In addition, the turntable 71 drives the roller 72 to rotate along the top inclined surface of the inclined disk 73, and with the cooperation of the spring 76 and the movable rod 75, the filter net 6 can move up and down, thus greatly improving the filtering efficiency of the filter net 6.
