Description

Technical Field

[0001] This utility model relates to the field of structural adhesive technology, specifically a vacuum dispersion and stirring device for structural adhesives. Background Technology

[0002] Structural adhesives are high-strength adhesives (compressive strength > 65 MPa, steel-to-steel tensile bond strength > 30 MPa, shear strength > 18 MPa), capable of withstanding large loads, and resistant to aging, fatigue, and corrosion. They exhibit stable performance throughout their expected lifespan and are suitable for bonding structural components subjected to high forces. During the production of structural adhesives, other additives need to be added, thus requiring thorough mixing of all raw materials.

[0003] For example, Chinese utility model patent CN214810408U discloses a liquid silica gel vacuum stirring device, including a stirring tank, a lower tank cover fixedly provided at the bottom of the stirring tank, three support legs fixedly provided at the bottom of the stirring tank, an upper tank cover fixedly provided at the bottom of the stirring tank, and a stirring assembly provided inside the stirring tank. The stirring assembly includes a gear ring, a first connecting shaft, a first transmission gear, three second transmission gears, and three second connecting shafts. The gear ring is fixedly provided on the inner wall of the stirring tank, and the first transmission gear is fixedly provided on the top of the first connecting shaft. The beneficial effect of this utility model is that the drive motor can drive the first connecting shaft to rotate. Under the meshing cooperation of the first transmission gear and the three second transmission gears, the three transmission gears can rotate along the gear ring, thereby causing the first stirring rod provided on the surface of the first connecting shaft and the second stirring rod provided on the surface of the second connecting shaft to perform staggered stirring of the material, thus improving the stirring efficiency.

[0004] However, existing structural adhesive vacuum dispersion and mixing devices filter materials by connecting the suction pipe to the suction end of the vacuum pump and fixing a filter screen at the other end of the suction pipe. The filter screen is not easy to disassemble, and impurities tend to accumulate over time, affecting the suction effect.

[0005] To address these issues, we propose a structural adhesive vacuum dispersion and mixing device. Utility Model Content
