Description

Technical Field

[0001] The invention belongs to the technical field of coating production, and in particular relates to an automatic mixing and proportioning device for coating production and a proportioning method thereof. Background Art

[0002] Paints are widely used in many fields such as construction, furniture, automobiles, and ships. From exterior wall painting to interior spraying, from anti-corrosion treatment to decorative effects, the use of paints is indispensable. The quality of paints directly affects the performance and service life of the final product, and this quality depends to a large extent on the mixing ratio accuracy during the production process, and mixing devices are used in the production process of paints.

[0003] For example, the application number is 201810829712.2, which is an easy-to-clean proportioning device for the production of environmentally friendly paint.

[0004] The above patent proposes a proportioning device for environmentally friendly paint production that is easy to clean. In view of the problem that a paint proportioning device design does not have the function of cleaning, does not have the function of grinding, and has uneven stirring, the following scheme is proposed, including a fixed plate, the bottom outer wall of the fixed plate is fixed with four support columns by bolts, and the four support columns are respectively located at the four corners of the bottom outer wall of the fixed plate, the top outer wall of the fixed plate is fixed with two support plates by bolts, and the two support plates are respectively located on both sides of the top outer wall of the fixed plate, the top outer wall of the fixed plate is fixed with a mixing box by bolts, and the mixing box is located near the middle of the top outer wall of the fixed plate.

[0016] An automatic mixing and proportioning method for coating production, the proportioning method comprising the following steps: Since paint barrels are arranged on both sides of the mixing rack, two controllers are arranged on the front of the mixing rack, and the controllers can control the corresponding paint barrels. When the raw materials need to be mixed, they are discharged through the feeding pipe. When the raw materials are discharged, they will overlap on the top of the sealing ring, and the weighing device in the sealing ring will weigh the accumulated raw materials. When the mixing and proportioning device is in use, the feed pipe, the auxiliary plate and the paint barrel can be clamped with the connecting plate, and the feed plate can be inserted with the paint barrel. When the mounting plate is clamped with the connecting plate through the limit plate, the threaded rod is driven to rotate, and the concave plate moves on the surface of the threaded rod.

Since the spur gear is meshed with the rack plate 2, a plurality of rack plates 2 are meshed with the corresponding rack plate 1, the rack plate 1 will drive the sealing plate to rotate with the column as the center, and the four sealing plates will move closer to each other during the rotation.
