[0022] refer to Figure 4 The limiting mechanism 9 includes a limiting plate 91, the rear side of the limiting plate 91 is rotatably connected to the two sides of the front side of the ink cartridge 2, a slot 92 is provided at the top of the rear side of the limiting plate 91, a bayonet 93 is provided inside the slot 92, a mounting box 94 is sleeved on the rear side of the surface of the bayonet 93, the rear side of the mounting box 94 is fixedly connected to the front side of the ink cartridge 2, a bevel 95 is fixedly connected to the rear side of the bayonet 93, a bevel 96 is provided on the rear side of the top of the bevel 95, a screw 97 is threadedly connected to the internal thread of the bevel 96, and the top of the screw 97 extends to the top of the mounting box 94.

[0023] As a technical optimization solution of the present invention, by setting a limiting mechanism 9, the filter 7 can be limited to prevent the filter 7 from loosening during use, resulting in the filter 7 being unable to fit tightly with the ink cartridge 2, thereby improving the stability of the filter 7 in use.

[0024] refer to Figure 4 Both sides of the interior of the inclined block 95 are slidably connected with a cross bar 10, and the surface of the cross bar 10 is fixedly connected to the inner wall of the installation box 94.

[0025] As a technical optimization solution of the present invention, by setting the cross bar 10, the inclined block 95 can be stabilized in sliding, avoiding shaking of the inclined block 95 during sliding movement, which causes the inclined block 95 to loosen, thereby improving the sliding stability of the inclined block 95.

[0026] refer to Figure 4 The surface of the cross bar 10 is sleeved with a tension spring 11, the front side of the tension spring 11 is fixedly connected to the rear side of the inclined block 95, and the rear side of the tension spring 11 is fixedly connected to the rear side of the inner wall of the mounting box 94.

[0027] As a technical optimization solution of the present invention, by setting a tension spring 11, the inclined block 95 can be pulled to automatically reset and move, avoiding the inclined block 95 being unable to automatically return to its original position after losing its limit and requiring manual reset, thereby improving the convenience of using the inclined block 95.

[0028] refer to Figure 4 Both sides of the inclined block 2 96 are fixedly connected with a sliding sleeve 12 , a sliding rod 13 is provided inside the sliding sleeve 12 , and the surface of the sliding rod 13 is fixedly connected to the inner wall of the mounting box 94 .

[0029] As a technical optimization solution of the present invention, by setting the sliding sleeve 12 and the sliding rod 13, the sliding of the inclined block 2 96 can be stabilized, avoiding shaking of the inclined block 2 96 during the sliding movement, causing the inclined block 2 96 to loosen, and improving the sliding stability of the inclined block 2 96.

[0030] refer to Figure 4 The top of the screw rod 97 is fixedly connected with a knob 14 , and the knob 14 is located on the top of the mounting box 94 .

[0031] As a technical optimization solution of the present invention, by providing the knob 14, it is possible to facilitate the user to rotate the screw 97, thereby preventing the screw 97 from being difficult to be pinched by the user, resulting in the screw 97 being difficult to rotate, and improving the rotation efficiency of the screw 97.

[0032] refer to Figure 1 A handle 15 is fixedly connected to the front side of the horizontal plate 8 , and the handle 15 is located on the front side of the ink cartridge 2 .

[0033] As a technical optimization solution of the present invention, by providing a handle 15, it is convenient for the user to pull the horizontal board 8 to move, avoiding the horizontal board 8 being difficult to buckle during the movement process, resulting in the horizontal board 8 being difficult to pull, thereby improving the control efficiency of the horizontal board 8.

[0034] The working principle and usage process of the present invention are as follows: when in use, the figure shows the state of the limit plate 91 positioning the horizontal plate 8, the square frame 6 and the filter 7. The impurities in the ink are filtered through the large-surface filter 7, and the filter 7 will not be blocked. When the filter 7 needs to be taken out for cleaning, the screw 97 is rotated, and the screw 97 drives the inclined block 2 96 to move upward, and the inclined block 1 95 loses the limit of the inclined block 2 96. The pulling force of the tension spring 11 drives the inclined block 1 95 to move backward, and the inclined block 1 95 drives the latch pin 93 to exit the interior of the slot 92. After the slot 92 loses its positioning, the limit plate 91 can be rotated to separate the limit plate 91 from the horizontal plate 8, and the horizontal plate 8 is pulled to move forward. The horizontal plate 8 drives the square frame 6 and the filter 7 to exit the interior of the ink cartridge 2, and the filter 7 is taken out for cleaning.

[0035] To sum up: the inking device for inkjet printing, through the coordinated use of the box 1, ink cartridge 2, printing roller assembly 3, partition 4, ink supply assembly 5, frame 6, filter screen 7, cross plate 8 and limiting mechanism 9, has the advantage of good anti-blocking effect, and solves the problem of filtering the ink sediment inside the ink cartridge through the filter plate inside the ink outlet tube. Due to the thin diameter of the ink outlet tube and the small area of ​​the filter plate, when the filter plate is blocked by the sediment, the filter plate will not be able to continue to pass the ink, resulting in the blockage of the ink outlet tube, which reduces the stability of the inking device.
