Description

Technical Field

[0001] This utility model relates to the field of water-based coating liquid technology, specifically to a multi-component synchronous metering and dosing device for water-based coating liquid. Background Technology

[0002] The coating solution is a high-molecular-weight water-soluble liquid made primarily of polyvinyl alcohol, modified with nanomaterials, possessing both adhesive and oxygen barrier properties. After coating, the solution achieves a dyne value of 42 and an oxygen barrier of 1cc, allowing for direct printing and application in liquid packaging (e.g., milk) and dry goods packaging (e.g., biscuits, mooncakes).

[0003] Chinese utility model patent CN216224579U discloses a feeding device for an aqueous coating liquid, including a base, a solid crushing box, and an aqueous storage box. The solid crushing box is installed on one side of the top of the base, and the aqueous storage box is installed on the other side of the top of the base. Foot-brake rollers are installed at the bottom of the base. This utility model can automatically transport not only solid raw materials for the coating liquid but also liquid raw materials, without manual feeding. It is fast, efficient, easy to move, flexible, and has strong overall stability. The solid raw materials are crushed before being transported, which improves the efficiency of the subsequent reaction, saves time, and is less prone to blockage during transport, keeping the feeding smooth. It is simple to operate and easy to use. However, the device lacks a raw material temperature control structure, making it unable to adapt to the storage and transport temperature requirements of different raw materials. It does not have precise transport and on / off control components, making it difficult to control the raw material transport ratio. There is no anti-accumulation auxiliary structure, so solid raw materials may still accumulate and blockage during transport after crushing. The uniformity and stability of the batching are insufficient, and the production process needs to be optimized, affecting the improvement of production efficiency. Therefore, this utility model proposes a multi-component synchronous metering and dosing device for aqueous coating liquid to solve the above problems. Utility Model Content
