Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane adhesive preparation equipment, and specifically to a polyurethane adhesive preparation device. Background Art

[0002] Polyurethane adhesives refer to adhesives containing urethane groups (-NHCOO-) or isocyanate groups (-NCO) in the molecular chain. The molecular chain of polyisocyanate contains isocyanide groups (-NCO) and urethane groups (-NH-COO-), so polyurethane adhesives exhibit high activity and polarity. They have excellent chemical adhesion to substrates containing active hydrogen, such as porous materials like foam, plastic, wood, leather, fabric, paper, ceramics, etc., and smooth-surface materials like metal, glass, rubber, plastic, etc. During the production process of polyurethane adhesives, a stirring device is required to mix various raw materials for reaction.

[0003] In the publicly disclosed Chinese patent application, the publication number: CN218530768U, the patent name: An esterification stirring device, includes a stirring device body; a stirring chamber is provided inside the stirring device body; a cover plate is provided at the top of the stirring chamber; several groups of second support columns are arranged in a circular array at the top edge of the cover plate; a top plate is provided at the top of several groups of the second support columns; two groups of electric push rods are symmetrically provided at the bottom edges on both sides of the top plate; the two groups of electric push rods are vertically arranged, and the output ends extend below the cover plate; a cleaning ring is drivingly connected to the output ends of the two groups of electric push rods; a circular scraper is provided at the bottom of the cleaning ring; the cutting edge of the circular scraper is movably abutted against the inner wall of the stirring chamber; a stirring mechanism is provided below the cover plate.

[0004] Although, in this prior art, by setting a cleaning ring and a circular scraper in the stirring chamber, and using the electric push rod to drive the circular scraper to scrape the polyurethane semi-finished products or finished products adhered to the inner wall of the stirring chamber from top to bottom, it not only improves the cleaning efficiency but also avoids waste and reduces production costs. However, this prior art has certain limitations. In this prior art, the electric push rod is used to push the circular scraper to lift and lower. During the downward movement of the circular scraper, it scrapes and cleans the polyurethane semi-finished products or finished products adhered to the inner wall of the stirring device body, thereby achieving cleaning. In the specific implementation process of this prior art, the cleaning efficiency is low. Summary of the Utility Model
