Powder coating dispersion machine

Abstract

The invention discloses a powder coating dispersion machine which is characterized in that a stirring cavity is formed in a dispersing device main body, a sleeving inner frame is sleeved with the stirring cavity, a supporting frame is fixedly connected to the upper end face of the dispersing device main body, and a rotary stirring rod is rotatably connected to the middle of the supporting frame; the lower end face of the rotating stirring rod extends to the middle of the stirring cavity, a driving device is arranged on the upper end face of the rotating stirring rod, the sleeving inner frame comprises a sleeving inner frame body, the sleeving inner frame body is rotationally connected to the interior of the stirring cavity, and a rotating ring is rotationally connected to the upper end face of the sleeving inner frame body; the outer diameter of the rotating ring is matched with the inner diameter of the stirring cavity, a limiting rod is fixedly connected to the side end face of the rotating ring, a limiting groove matched with the limiting rod is formed in the upper portion of the dispersing device body, and a containing bag is clamped between the dispersing device body and the sleeving inner frame. The device has the effect of stirring thepowder coating, and the powder is prevented from solidifying and crusting on the inner wall of the container.

Description

technical field [0001] The invention relates to the technical field of stirring, in particular to a powder coating disperser. Background technique [0002] Powder coating is a solid powder synthetic resin coating composed of solid resin and pigments, fillers and additives. Unlike ordinary solvent-based paints and water-based paints, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. There are two types of powder coatings, thermoplastic and thermosetting. Thermoplastic powder coatings have poor film appearance (gloss and leveling) and poor adhesion to metals, so they are rarely used in the field of automotive coatings. Thermosetting powder coatings are generally used in automotive coatings, and thermosetting powder coatings are The thermosetting synthetic resin is used as the film-forming substance. During the drying process, the resin is melted first, and then cured i...

AI Technical Summary

Problems solved by technology

[0004] Existing powder coating dispersing machines mostly operate by placing the powder raw material in the container and stirring the rotor. However, due to the physical and chemical properties of the powder coating in actual use, it is easy to solidify on the surface of the container wall if it cannot be used up in a short period of time after stirring. The shell is difficult to clean, which reduces the effect of subsequent mixing. If bagging is used, it is difficult to mix due to the high viscosity of the paint
