Description

Technical Field

[0001] The utility model relates to the technical field of ink box production, in particular to a liquid outlet cover for an ink packaging container of a printing machine. Background Art

[0002] Ink is a substance used to form graphic information in the printing process, so ink plays a very important role in printing. It directly determines the gradation, color, clarity, etc. of the image on the printed product. There are always various situations when installing a new ink cartridge, the most common of which are no ink, ink cartridge failure, etc.

[0003] In a comparative document of a leak-proof ink cartridge proposed with publication number CN219731399U, it is specifically proposed that "it includes an oil storage cylinder and a sealing cover, an ink adjustment component is arranged in the oil storage cylinder, and the ink adjustment component includes an ink outlet tube, a plug, a guide rod, a connecting rod and an arc-shaped baffle; an adjustment slide groove is arranged on the circumference of one end of the ink outlet tube, the arc-shaped baffle is arranged in contact with the inner wall of the ink outlet tube, and an adjustment rod is fixed on the arc-shaped baffle, and a spring is fixed on the other end of the guide rod, and the other end of the spring is fixed on the inner wall of the oil storage cylinder."

[0004] The inventors found that the ink in the comparative document flows out from the ink outlet tube through the ink leakage hole, and the adjustment rod at the lower end is pulled to seal the internal ink. The operation steps are cumbersome, and the adjustment rod is located at the ink outlet tube. The ink is very easy to stain the hands during operation. For this reason, we proposed a liquid outlet cover for the ink packaging container of a printing machine. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A liquid outlet cap for an ink packaging container for a printing press comprises a cylinder, a cavity is arranged at the lower end of the cylinder, a spherical body is arranged at the lower end face of the cavity, a plurality of liquid leakage holes are opened along the circumferential direction on the circumference of the spherical body, a telescopic sleeve is arranged on the outer side of the cavity, and the telescopic sleeve controls the ink in and out by extrusion and stretching.

[0008] As a preference, a circle of protrusions is provided on the upper end of the telescopic sleeve, and the protrusions cooperate with a circle of grooves on the cavity.

[0009] As a preference, a through hole is provided at the end of the telescopic sleeve, and the cross-sectional curvature of the through hole is consistent with the curvature of the spherical body.

[0010] As a preferred embodiment, the circumference of the telescopic sleeve is hollowed out, and symmetrical connecting strips are arranged on the circumference of the telescopic sleeve, and the connecting strips are connected up and down in an L-shape.

[0011] As a preference, clamping strips are provided on both sides of the connecting strip.

[0012] As another preferred embodiment, the telescopic sleeve is molded with natural or synthetic resin as the main component.

[0013] Beneficial effects of the utility model:

[0014] In the utility model, a cavity is provided at the lower end of a cylinder, and a telescopic sleeve is clamped on the outer wall of the cavity. The telescopic sleeve is stretched outwards to leave a gap between the telescopic sleeve and the spherical body, and ink flows out downwards along the outer surface of the spherical body through the leakage hole; the telescopic sleeve is pressed inwards to make the telescopic sleeve and the spherical body fit each other, so that the ink inside the ink cartridge is sealed.

[0015] In summary, the device has the advantages of simple operation and good sealing effect, and is particularly suitable for the field of ink cartridge production technology. BRIEF DESCRIPTION OF THE DRAWINGS
