Description

Technical Field

[0001] This utility model relates to the field of water-based solvent production technology, specifically to a feeding mechanism for water-based solvent production. Background Technology

[0002] Water-based solvents refer to coating products that use water as a solvent or dispersion medium. They are mainly used to replace traditional organic solvent-based coatings. Water-based solvents use water as a carrier and contain no or a small amount of environmentally friendly additives such as propylene glycol methyl ether. They are environmentally friendly, safe, and pollution-free. In the production process of water-based solvents such as coatings, inks, and adhesives, it is usually necessary to mix various raw materials such as resins, additives, deionized water, and solvents in a specific ratio to ensure the stability, viscosity, and performance of the final product.

[0003] In the production of water-based solvents, traditional feeding mechanisms typically employ a fixed structure, resulting in poor equipment compatibility and difficulty in adapting to different sizes of feeding tanks. This affects production flexibility and material change efficiency. Furthermore, most existing discharge pipes lack automatic cleaning functions, and residual materials can easily cause cross-contamination. Utility Model Content

The mounting base 8 is equipped with multiple sets of synchronously rotating and opening / closing plates 10, enabling rapid opening and closing of the bottom of the storage tank 4 to prevent raw material leakage. During feeding, the drive wheel 607 drives the first toothed ring 606 to rotate, causing the rotating frame 601 and scraper 602 to rotate along the pipe wall to scrape off residual materials. The scraper block 603 is adjusted in position on the scraper 602 by rotating the screw 604, and works in close contact with the pipe wall with the rubber sealing sleeve 605 to ensure thorough cleaning without dead corners, thus cleaning the materials on the scraper 602. This mechanism operates automatically when changing materials or stopping the machine, effectively preventing cross-contamination caused by solvent residue and ensuring production cleanliness.
