Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of powder coating raw material proportioning equipment of quantitative feeding. BACKGROUND

[0002] Powder coating is a new type of solvent-free solid powder coating, and its main component is resin, which is the base material of powder coating and plays a key role in bonding and forming a coating film. Before mixing the powder coating raw materials, raw material inspection is required to check the appearance of each raw material to ensure that there are no impurities, lumps or discoloration abnormalities. For resin raw materials, they should be uniform granular or flaky, and the color should meet the standard requirements. Many raw materials may absorb some moisture during storage. For powder coating, excessive moisture content can affect the performance of the coating.

[0003] Chinese patent CN220677719U proposes a powder coating batching device, which includes a mixing tank and a batching part. The mixing tank is installed with several batching parts. The batching part includes a raw material storage tank, and a re-weighing tank is arranged below the raw material storage tank. Weighing devices are installed on the raw material storage tank and the re-weighing tank. The re-weighing tank can be used to check the batching quality. A negative pressure conduit is arranged on the mixing tank, and a suction device is connected to the negative pressure conduit. A stirring blade is rotatably installed in the mixing tank. A weighing hook is fixedly installed on the raw material storage tank, and an electronic hoist scale is installed on the weighing hook as a weighing device. A discharge pipe is arranged below the raw material storage tank. The raw materials are discharged and weighed separately by the batching part. The raw material storage tank and the re-weighing tank cooperate with each other to check the quality of each component of the batching material.

[0004] However, the technical solution of this patent has the following problems:
