Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printing, in particular to a bubble-breaking and anti-sinking secondary ink cartridge for inkjet printing. Background Art

[0002] The ink supply of existing inkjet printers is mostly to pump ink from a fixed ink barrel into a secondary ink cartridge on a printing carriage, and then the secondary ink cartridge supplies ink to the nozzle. When the ink is filled into the ink cartridge and the carriage moves, bubbles will be generated in the ink, and then the bubbles will enter the nozzle, affecting the printing effect. The existing method is to install a defoaming filter device between the secondary ink cartridge and the nozzle to defoam, but this will cause some pressure changes, which will affect the printing effect. In addition, the ink outlet flow rate of the secondary ink cartridge is slow, so it is easy to produce sedimentation and condensation at the outlet of the ink cartridge. The condensation blocks enter the nozzle and damage the nozzle. Utility Model Content

[0003] The purpose of the utility model is to provide a bubble breaking and anti-sinking two-stage ink cartridge for inkjet printing in order to solve the above-mentioned problems, as described below.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The utility model provides a bubble breaking and anti-sinking secondary ink cartridge for inkjet printing, comprising a secondary ink cartridge body, wherein a bubble breaking block for eliminating bubbles in ink is placed in the secondary ink cartridge body;

[0006] There is a gap between the bubble breaking block and the inner wall of the secondary ink cartridge body;

[0007] The foam breaking block comprises several layers of filter screens for defoaming.

[0008] When the above-mentioned bubble-breaking and anti-settling secondary ink cartridge is used for inkjet printing, during operation, when the inkjet carriage moves, the ink in the secondary ink cartridge body fluctuates to a certain extent, causing the bubble-breaking block to swing back and forth in the secondary ink cartridge body. When the ink fluctuates, the compressed bubbles will burst through the filter screen. At the same time, the bubble-breaking block will stir the bottom of the secondary ink cartridge body when it swings, causing the ink at the bottom to flow and prevent sedimentation.

[0009] Preferably, the bubble breaking block comprises a frame, the frame is placed in the secondary ink cartridge body, and there is a gap between the frame and the inner wall of the secondary ink cartridge body, and a plurality of layers of filter screens are vertically arranged on the frame.

[0010] Preferably, the mesh sizes of the several layers of filter screens of the bubble breaking block decrease from top to bottom.

[0011] Preferably, the filter screen has a specification of 0.5 mesh.

[0012] Preferably, the ink inlet of the secondary ink cartridge body is located between the first two layers of filters at the top.

[0013] Preferably, a plurality of feet for counterweight are provided at the bottom of the frame, and the feet are in contact with the bottom of the inner wall of the secondary ink cartridge body.

[0014] Preferably, the foot is a cone, and the bottom of the foot is hemispherical.

[0015] Preferably, the base foot is offset from the ink outlet at the bottom of the secondary ink cartridge body.

[0016] The beneficial effects are:

[0017] A bubble breaking block is provided to eliminate ink bubbles. When the inkjet carriage moves, the bubble breaking block swings back and forth in the secondary ink cartridge body, allowing the ink to pass through the filter. The compressed bubbles will burst, and the bubble breaking block will stir the bottom of the secondary ink cartridge body when it swings, allowing the ink at the bottom to flow, thereby preventing ink deposition and damaging the nozzle. This defoaming method will not affect the inkjet pressure, thereby ensuring the printing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 As shown, the utility model provides a bubble breaking and anti-sinking secondary ink cartridge for inkjet printing, comprising a secondary ink cartridge body 1, a bubble breaking block 2 for eliminating bubbles in the ink is placed in the secondary ink cartridge body 1, the top of the bubble breaking block 2 is slightly higher than the ink inlet 3 and slightly lower than the set liquid level, which can prevent waves and reduce bubble generation, and utilize the shaking of the inkjet printing carriage to break the generated bubbles, and at the same time stir the bottom ink to prevent sedimentation;

[0027] There is a gap between the bubble breaking block 2 and the inner wall of the secondary ink cartridge body 1, and the gap is provided so that the bubble breaking block 2 can move in the secondary ink cartridge body 1;

[0028] The bubble breaking block 2 comprises several layers of filter screens 5 for defoaming. When bubbles pass through the meshes of the filter screens 5, they are compressed, causing the bubbles to burst.

[0029] As an optional embodiment, the bubble breaking block 2 includes a frame 4, which is placed in the secondary ink cartridge body 1, and there is a gap between the frame 4 and the inner wall of the secondary ink cartridge body 1, and a plurality of layers of filter screens 5 are vertically arranged on the frame 4.

[0030] The mesh sizes of the several layers of filter screens 5 of the bubble breaking block 2 decrease from top to bottom, and the specifications of the filter screen 5 are 50 to 300 meshes. Due to the different sizes of bubbles, setting multiple layers of filter screens 5 with different mesh sizes can ensure that the bubbles are completely eliminated.

[0031] The ink inlet 3 of the secondary ink cartridge body 1 is located between the first two layers of filter screens 5 at the top.

[0032] A plurality of feet 6 for balancing weights are arranged at the bottom of the frame 4, and the feet 6 are in contact with the bottom of the inner wall of the secondary ink cartridge body 1, so that the ink deposited at the bottom of the secondary ink cartridge body 1 is stirred and dispersed by the feet 6.

[0033] The foot 6 is a cone, and the bottom of the foot 6 is hemispherical. This design can reduce the friction between the foot 6 and the bottom of the inner wall of the secondary ink cartridge body 1, thereby increasing the movement frequency and distance of the foot 6 in the secondary ink cartridge body 1, and further improving the stirring effect.

[0034] The bottom foot 6 is misaligned with the ink outlet at the bottom of the secondary ink cartridge body 1 . The ink outlet is generally arranged at the bottom of the secondary ink cartridge body 1 , and the bottom foot 6 will never pass through the ink outlet, so as to avoid the bottom foot 6 blocking the ink outlet and the ink outlet hindering the movement of the bottom foot 6 .

[0035] With the above structure, during operation, when the inkjet carriage moves, the ink in the secondary ink cartridge body 1 fluctuates to a certain extent, causing the bubble breaking block 2 to swing back and forth in the secondary ink cartridge body 1. When the ink fluctuates, the compressed foam will burst through the filter 5. At the same time, the bubble breaking block 2 will stir the bottom of the secondary ink cartridge body 1 when it swings, causing the ink at the bottom to flow and prevent sedimentation.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
