Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive stirring, and in particular relates to an adhesive stirring device. Background Art

[0002] Adhesives are an important component of packaging materials, which determine the physical and chemical properties of packaging materials such as bonding strength, water resistance, and heat resistance. By mixing additives, the properties of adhesives can be adjusted to suit different packaging needs. For example, additives can be used to enhance the adhesion of adhesives or adjust their fluidity so that they can better contact the surface of packaging materials and form a strong bond. The introduction of additives can improve the properties of packaging materials, such as increasing tensile strength, abrasion resistance, and weather resistance. These improvements in properties can make packaging materials more durable and adaptable to different environmental conditions, thereby protecting the contents of the package. The right formulation and uniform mixing can reduce the scrap rate and ensure a stable production process while reducing costs. Some additives can help adhesives meet environmental standards, such as reducing volatile organic compound (VOC) emissions or using biodegradable ingredients to reduce environmental impact. Different packaging applications have different requirements, such as food packaging needs to meet food safety standards, and pharmaceutical packaging requires high temperature and corrosion resistance. By mixing adhesives and additives, suitable products can be customized according to specific packaging needs. In summary, the purpose of mixing adhesives and additives is to adjust and optimize the performance of adhesives, improve the characteristics of packaging materials, increase production efficiency, and ensure that products meet environmental protection and specific demand standards.

[0025] Compared with the prior art, the adhesive stirring device provided by the utility model has the beneficial effect that one side of the scraper is fixedly connected to the connecting arm, and the other side is freely extended to form an upwardly inclined structure, which is conducive to the scraper lifting the material upward.

[0026] The first stirring shaft and the second stirring shaft are arranged in an axially staggered manner to form a circulating stirring area, so that the adhesive and the additive are fully mixed. This staggered movement can effectively break the particles, increase the mixing efficiency, effectively break and disperse the solid particles, and ensure the fluidity of the mixed material in the device.
