On June 4, 2025, according to information from the National Intellectual Property Administration, Shanghai Huayi Resin Co., Ltd. obtained a patent titled “Polyurethane Adhesive Dispersion Device,” with authorization announcement number CN222930763U, and an application date of May 2024.
The patent abstract states that this utility model belongs to the field of dispersion device technology, specifically a polyurethane adhesive dispersion device, comprising a base; through the configuration of the dispersion mechanism, rapid material discharge is achieved, reducing the residual amount of polyurethane adhesive in the dispersion tank and minimizing post-dispersion cleanup efforts, thereby enhancing overall dispersion efficiency. Polyurethane adhesive raw materials are introduced into the dispersion tank, and the polyurethane adhesive raw material is stirred and dispersed using a drive rod and a stirring rod pair. After dispersion is complete, the drive device can be used to drive the first lead screw to rotate, thereby causing the transmission plate to lift the cover plate and the stirring rod above it out of the dispersion tank. Simultaneously, the transmission plate moves the rack via the fixed plate, after which the gear engages with the rack, causing the gear to rotate the positioning rod, which in turn rotates the dispersion tank. the polyurethane adhesive inside can be rapidly discharged under the force of gravity and falls through the discharge chute into the collector located at the bottom of the base, thereby improving the efficiency of dispersion and discharge.
