Description

Technical Field

[0001] The utility model relates to the technical field of ink mixing, in particular to an ink mixing variable speed agitator. Background Art

[0002] In the process of preparing ink, the raw materials need to be mixed together and stirred to make them fully mixed, so a stirrer is needed.

[0003] Printing is a technology that transfers ink to the surface of paper, fabric, plastic, leather and other materials through processes such as plate making, inking and pressurization to reproduce the content of the originals such as text, pictures, photos, anti-counterfeiting, etc. in batches. The ink is composed of colorants, binders and auxiliary agents, which are mixed and rolled to form ink. Color, body (usually the flow and rheological properties of ink such as consistency and fluidity are called the body of ink) and drying properties are the three most important properties of ink.

[0004] For example, the prior art Chinese patent publication number "CN217962360U" provides a flexible simulated aqueous ink production agitator, including a support frame, a mounting cylinder is fixedly connected to the support frame, a discharge cylinder is fixedly connected to the bottom of the mounting cylinder, a first feed nozzle and a second feed nozzle are fixedly connected to the top of the mounting cylinder, a stirring mechanism is arranged inside the mounting cylinder, a discharge mechanism is arranged inside the discharge cylinder, and a power mechanism is fixedly connected to the top of the mounting cylinder.

[0005] The first motor of the device can drive the rotating tube to rotate around its own axis, and the rotation of the rotating tube drives the stirring blades to rotate synchronously around the axis of the rotating tube. This design solves the shortcomings of the existing technology. The stirring blades and the stirring fan cooperate with each other to increase the chaos between the toner and water, and improve the mixing and stirring effect between the toner and water. In addition, after mixing and stirring, the auger can automatically output the mixture of toner and water to the outside, which is convenient for subsequent production and processing.

[0006] The existing ink mixing variable speed agitator is quite laborious when changing the speed of the stirring structure, and it is not convenient to adjust the height of the variable speed structure, which can easily cause the variable speed structure to separate or bump, resulting in damage to the variable speed structure and affecting the rotation of the stirring structure. At the same time, during the ink mixing process inside the stirring barrel, the ink will splash and fall on the surface of the variable speed structure, causing the surface of the variable speed structure to be soaked and slippery, affecting the rotation of the stirring structure.
