Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning device for a paint tank. Background Art

[0002] As we all know, in the paint production process, it is often not possible to produce only one type of paint on a single production line. Different types of paint contain different chemical components. If the old paint cans are not thoroughly cleaned, the residual paint components may chemically react with the new paint, affecting the performance and quality of the new paint, resulting in poor painting effects or quality problems.

[0003] Cleaning paint cans can avoid cross-contamination between different colors and types of paint, especially for color-sensitive applications, to ensure color accuracy.

[0004] For example, a Chinese utility model patent discloses a cleaning device for cleaning a paint tank (publication number CN216606516U), which includes a motor, a liquid adding mechanism, and a cleaning mechanism.

The liquid adding mechanism is arranged on the outside of the rotating shaft, and the liquid adding mechanism includes a protective cover tube, to which the liquid adding tube and the adding mechanism are connected. The cleaning mechanism is fixedly connected to the rotating shaft and rotatably connected to the protective cover tube. The rotating shaft is located on the side wall of the protective cover tube and is connected to a stirring plate for stirring the liquid and cleaning agent in the protective cover tube. The rotating shaft is rotatably connected to the protective cover tube to facilitate the rotation of the rotating shaft. A sealing ring is sleeved on the outside of the rotating shaft. The arrangement of the corresponding mechanisms can improve the cleaning effect of the interior of the paint tank, making it less likely that the paint tank will be not cleaned properly, reducing the impact on the user's reuse of the paint tank, and at the same time, the user does not need to clean the paint tank multiple times, thereby improving the user's cleaning efficiency.

[0005] However, when the inventors implemented this device, they found the following defects: the contact area between the cleaning mechanism and the inner wall of the paint tank is large, and the cleaning device is not convenient to take out and put in the paint tank; the rotation speed of the cleaning mechanism is low, and the cleaning efficiency and cleaning effect of the inner wall of the paint tank need to be further improved.
