Description

Technical Field

[0001] This utility model belongs to the field of water-based ink production technology, and in particular relates to a closed ink tank for trial use in water-based ink. Background Technology

[0002] Water-based inks, as an environmentally friendly ink widely used in the printing industry, are gradually replacing traditional solvent-based inks due to their advantages such as low pollution and low volatility. In the pilot production of water-based inks, sealed ink tanks play a crucial role. They must not only ensure the ink's airtightness to prevent evaporation and contamination, but also meet practical operational needs such as convenient observation, sampling, and flexible adjustment of storage capacity.

[0003] Currently, the structure of commonly available water-based ink storage containers is relatively simple. Traditional ink containers generally consist of a single, fixed-volume container and a standard sealing cap. However, existing water-based ink storage containers have the following drawbacks in practical use:

[0004] First, the existing water-based ink storage tanks are typically one-piece molded and lack expandable space. Second, the sealing caps in existing water-based ink storage tanks do not provide space for the stirring shaft of an external stirring mechanism. Therefore, the water-based ink can only be stirred by removing the sealing cap, which easily causes ink to splatter during stirring, wasting ink and potentially polluting the working environment. In addition, existing water-based ink storage tanks lack convenient sampling devices. Obtaining ink samples of different heights requires additional tools, which is cumbersome and prone to ink contamination.

[0005] Therefore, it is essential to invent a closed ink tank for the trial use of water-based inks. Utility Model Content

[0006] To address the above problems, this utility model proposes a closed ink tank for trial use in water-based inks. The technical solution used is as follows:

[0007] A water-based ink testing closed ink tank includes an ink tank, an observation window, a sealing cap, and a handle. The observation window is fixed to the front side of the ink tank, and the sealing cap is fixed to the top of the ink tank by fastening. Handles are rotatably installed on both sides of the ink tank. The observation window includes a window frame and a window body, wherein the window frame is fixed to the front side of the ink tank, and the window body is rotatably installed inside the window frame. The window body is a plate made of transparent material.

[0008] Furthermore, the ink container includes a container body, a folding sleeve, a positioning ring, and a positioning frame; an observation window is fixed to the front side of the container body, and handles are rotatably installed on both sides of the container body; a folding sleeve is fixed to the upper end of the container body, wherein a positioning ring is fixed to the upper end of the folding sleeve, and a sealing cap is fixed to the upper end of the positioning ring by fastening; a positioning frame is fixed to both sides of the positioning ring by bolts, wherein a groove adapted to the handle is opened on the lower side of the positioning frame. This design can expand the storage space for water-based ink when needed.

[0009] Furthermore, the observation window also includes a handle, a valve, and a sampling tube. The handle is fixed to the outer side of the middle part of the window body by bolts; the valve is fixed to the outer edge of the window body by a connector, and the other end of the valve is fixed to a sampling tube by a connector. This arrangement facilitates sampling of water-based inks at different heights.

[0010] Furthermore, the sealing cap includes a half-cap, a half-stud tube, a sleeve, and a sealing cap. Two half-caps are provided, and the two half-caps are mirror images of each other. Each half-cap is fastened to the upper end of the ink tank, and a half-stud tube is fixed to the upper side of each half-cap at its contact position. The sleeve is threadedly engaged and sealed to the outer sides of the two half-stud tubes, and a sealing cap is threadedly engaged and sealed inside the upper end of the sleeve. This arrangement seals the upper end of the ink tank, thereby reducing the evaporation of water-based ink. Additionally, when the water-based ink is stirred by the stirring shaft of an external stirring mechanism, it prevents the water-based ink from splashing out inside the ink tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The ink tank of this utility model is designed such that, during normal use, the folding sleeve is in a folded state, thereby storing water-based ink inside the tank. When there is too much water-based ink, the folding sleeve can be unfolded and the handle placed vertically, so that the positioning frame is fastened to the upper part of the handle. In this way, the storage space of water-based ink can be expanded by using the unfolded folding sleeve.

[0013] 2. The observation window of this utility model allows for observation of the water-based ink inside the ink tank through the transparent window during use. Furthermore, when it is necessary to sample water-based ink at different heights inside the ink tank, the sampling tube can be positioned at the corresponding height using the handle, and then the valve can be opened to allow the water-based ink at that height to flow out through the sampling tube.

[0014] 3. The sealing cap of this utility model can seal the upper part of the ink tank during actual use, effectively reducing the evaporation of water-based ink. When it is necessary to stir the water-based ink in the ink tank, the sleeve and the sealing cap can be removed first, and the stirring shaft of the external stirring mechanism can be placed into the ink tank, with the semi-spiral tubes covering the stirring shaft. Then, the sleeve is fixed on the two semi-spiral tubes. In this way, the two half-tank caps can prevent the ink from splashing out of the ink tank when the stirring shaft stirs the water-based ink.
