Description

Technical Field

[0001] This utility model relates to the field of ink production equipment technology, specifically to an ink mixing device. Background Technology

[0002] Ink is a colloidal substance made by mixing pigments, binders, additives and other components. It is mainly used to form a firm coating with specific colors, patterns or text on the surface of various substrates such as paper, plastics, metals and fabrics. Color (hue), body (rheological properties such as viscosity and fluidity) and drying properties are the three most important properties of ink. During the ink production process, various ink raw materials need to be fully mixed by stirring and dispersing equipment.

[0003] During the process of adding powder to the mixing and dispersing equipment, the powder needs to be slowly added into the ink mixing tank. The pouring process is uncontrollable, and impurities and coarse particles in the powder (especially solid resin particles) will cause the powder (especially solid resin particles) to accumulate, which will lead to uneven dispersion. In addition, during the dispersion process, when the mixing paddle rotates at high speed to mix the raw materials, it will release a lot of heat. When the heat reaches a certain temperature, it will cause the components of the raw materials in the ink to denature, which will affect the ink quality. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figures 1-6 As shown, in one embodiment, an ink mixing device includes: a mixing tank 1, which has a mixing chamber 11 inside for mixing raw materials;

[0033] The mixing chamber 11 of the mixing tank 1 is equipped with a filter screen 2 for filtering the powdered raw materials.

[0034] For example, the filter screen 2 is detachably installed on the top side of the mixing chamber 11, which facilitates daily cleaning, maintenance and replacement, and can also be flexibly adjusted according to the filtration needs of different powders; specifically, the filter screen 2 is a stainless steel screen, which has good corrosion resistance and wear resistance, and can maintain stable performance in the environment of various chemical substances that may be contained in ink raw materials. At the same time, the mesh size of the stainless steel screen is precisely designed to efficiently intercept particles that do not meet the requirements, ensuring the filtration effect while extending the service life.

[0035] Understandably, when the operator puts powdered raw materials into the mixing chamber 11, the filter screen 2 will first filter and initially disperse the powder. Then, the powder passes through the filter screen 2 and enters the mixing chamber 11 under the action of gravity, while impurities and coarse particles are filtered out. This process effectively avoids impurities from mixing into the ink raw materials and affecting the final quality. It also solves the problem of uneven dispersion caused by the accumulation of powder particles, making the raw materials mix more thoroughly and evenly.

[0036] Furthermore, a liquid storage chamber 12 is provided outside the stirring chamber 11, surrounding the stirring chamber 11, and is used to cool the raw materials inside the liquid storage chamber 12; specifically, a liquid inlet 13 is provided on one side of the top of the liquid storage chamber 12 for introducing coolant; correspondingly, a liquid outlet 14 is provided on the other side of the bottom of the liquid storage chamber 12 for discharging the coolant after heat absorption; in addition, the liquid inlet 13 and the liquid outlet 14 are connected to the circulating water tank 6 through pipelines to form a complete coolant circulation system.

[0037] Understandably, after the inlet 13 and outlet 14 of the liquid storage chamber 12 are connected to the circulating water tank 6 through pipelines, the circulating water tank 6 will continuously deliver low-temperature coolant to the liquid storage chamber 12 through the inlet 13 during the entire process of stirring the raw materials. When this coolant flows in the liquid storage chamber 12, it can continuously carry away the heat emitted during the stirring process, which can effectively reduce the evaporation rate of the solvent in the ink raw materials, reduce the waste of raw materials and environmental pollution, and effectively solve the problem of ink composition denaturation caused by excessive temperature rise during powder mixing, thereby ensuring the quality stability of the ink.

[0038] Please continue reading. Figures 1-6 In this embodiment, the top of the mixing tank 1 is connected to the sealing top cover 3 to ensure that the mixing chamber 11 is in a relatively closed environment, reducing the leakage of raw materials and the entry of external impurities; specifically, the sealing top cover 3 and the mixing tank 1 are connected by a flange seal.

[0039] For example, the sealed top cover 3 is provided with a stirring device 4 and a ventilation device 5. The stirring device 4 is used to stir the raw materials, while the ventilation device 5 is used to extract dust and volatiles.

[0040] Specifically, a stirring device 4 is provided on the top of the sealing cap, and the stirring device 4 includes a drive motor 41 and a stirring rod 42.

[0041] It should be explained in detail that the stirring rod 42 is provided with one or more sets, and the top of the stirring rod 42 is rotatably connected to the output end of the drive motor 41 through a drive wheel to adapt to the stirring of raw materials of different batches and properties; wherein, the end of the stirring rod 42 is provided with multiple sets of stirring paddles 43, and each set of stirring paddles 43 is at a different height, so that the raw materials can be stirred and dispersed in all directions and at multiple angles through the staggered stirring paddles 43, thereby achieving full stirring of the raw materials, ensuring uniform mixing of the raw materials, and avoiding the phenomenon of insufficient mixing in some areas.

[0042] Furthermore, the stirring device 4 is equipped with exhaust devices 5 on both sides. The exhaust devices 5 include a support base 51 and an impeller 52. Specifically, the impeller 52 is located in the middle of the support base 51 and is rotatably connected to the support base 51, so that the impeller 52 can rotate flexibly within the support base 51, thereby generating suction force.

[0043] It should be noted that the top of the exhaust device 5 is connected to the waste collector 7 via a pipe, and is used to collect dust particles and volatiles.

[0044] Understandably, when the exhaust device 5 is started, the impeller 52 rotates at high speed to generate negative pressure, which draws in the dust and volatiles generated during the mixing process through the exhaust device 5, and then transports them through pipelines to the waste collector 7 for centralized collection and treatment. This not only effectively prevents dust and volatiles from spreading into the operating environment, but also allows for the unified treatment of these wastes, which is beneficial to environmental protection and resource recycling.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
