Description
Technical Field
[0001] The utility model relates to the technical field of powder coating production, in particular to a coating mixing and stirring machine for powder coating production. Background Art
[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coating and water-based coating, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coating is divided into two categories: thermoplastic and thermosetting. Thermoplastic powder coating has poor coating appearance and poor adhesion to metal, so it is rarely used in the field of automotive coating. Automotive coating generally uses thermosetting powder coating. Thermosetting powder coating uses thermosetting synthetic resin as film-forming material. During the drying process, the resin melts first and then solidifies into a smooth and hard coating after chemical cross-linking.
[0003] Generally, when producing powder coatings, a mixer is used to mix the materials. The materials are stirred by a stirring rod inside the mixer to achieve the effect of mixing the materials.
[0004] However, the existing paint mixing and agitating machines for powder coating production generally stir the materials by setting a stirring rod, which cannot mix the materials evenly, the materials at deep depths cannot be mixed, and after the mixed materials are discharged, the materials will remain on the inner wall of the mixing tank, making it difficult to clean the inside of the tank.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] 1. The utility model is provided with a limit ring, a semicircular plate, an auger and other components, and a motor drives the rotating rod to rotate and drives the fixed rod 1, the auger and the fixed rod 2 to rotate, the fixed rod 1 drives the corresponding limit ring to rotate, and at the same time the limit ring drives the arc plate and the semicircular plate to rotate, and the fixed rod 2 drives the corresponding scraper and the flipping plate to rotate, and the materials are repeatedly flipped by the rotation of the auger, the semicircular plate and the flipping plate so that the materials are evenly mixed inside the mixing tank, and the materials attached to the inner wall of the mixing tank are contacted with the arc plate and the scraper through the contact with the inner wall of the mixing tank, so that the materials attached to the inner wall of the mixing tank are removed, thereby achieving the effect that the device can evenly mix the materials and facilitate the cleaning of the mixing tank.
[0016] 2. The utility model provides an annular baffle, a pull rod, a blocking plate and other components.
