Description

Technical Field

[0001] The utility model relates to an anti-blocking powder feeder, belonging to the technical field of powder feeding. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, 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 coatings are divided into two categories: thermoplastic and thermosetting. Since no solvent is used, it is called powder coating. The main characteristics of powder coatings are harmlessness, high efficiency, resource saving and environmental protection.

[0003] The existing patent number is CN212595219U, which is a feeding device for preventing raw materials from being blocked for a powder coating color mixing machine. This device drives the rotating shaft to rotate through a servo motor, so that the rotating shaft drives the conical stirring rod and the auger to rotate at the same time. Under the action of the conical stirring rod, the pigment in the storage barrel is pre-stirred to prevent the pigment in the storage barrel from agglomerating. The conical bin can ensure that the pigment is connected to the material to avoid faults. Under the action of the auger, the pigment in the storage barrel can be pushed, so that the pigment is evenly introduced from the conical bin through the feeding pipe into the color mixing machine, avoiding the clogging of the feeding device and causing the pigment to be blocked. When the amount added is reduced, it is ensured that the color adjustment can reach the target color. However, when this device is in use, the compactness of powder materials at different positions is different, and the feeding amount needs to be controlled by a control valve. It is difficult to accurately control the feeding amount, and thus it is difficult to accurately control the feeding processing of the powder. Moreover, when feeding through an auger, the powder will be squeezed, and the incoming material will easily become block or flake, affecting the mixing processing effect of the powder material and other materials, and it is easy for some materials to adhere to the transparent window and affect the observation of the internal materials, which is not conducive to the later mixing and use of the powder material.
