Description

Technical Field

[0001] This utility model relates to the field of polyurethane adhesive processing technology, specifically to a polyurethane adhesive dispersion device. Background Technology

[0002] Polyurethane adhesives are adhesives containing urethane or isocyanate groups in their molecular chains. They exhibit high activity and polarity, demonstrating excellent chemical adhesion to substrates containing active hydrogen, such as porous materials like foam, plastics, wood, leather, fabrics, paper, and ceramics, as well as smooth-surfaced materials like metals, glass, rubber, and plastics. With superior performance, they have been widely used in many fields and are one of the most important varieties of the eight major synthetic adhesives.

The hydraulic push rod 5 pushes the output end downward, driving the dispersion mechanism 6 to move down and enter the working bucket 3. At this time, the drive motor 631 drives the working chamber 62 and the two sets of stirring racks 64 to revolve, stirring and dispersing the polyurethane adhesive. Then, the drive motor 6224 is started. The drive motor 6224 moves the rack 6223 through the threaded rod 6225, and drives the connecting piece 6231 to rotate through the gear 6221 and the rotating main shaft 621, thereby driving the two sets of rotating shafts 6233 to move along the through groove 6234, driving the two sets of stirring racks 64 to perform linear motion. During the movement of the rotating shaft 6233 along the through groove 6234, the rack 6233 and the stirring rack 64 can rotate by the cooperation of the rack 6236 and the gear 6238, which can further improve the dispersion effect of the polyurethane adhesive.
