Description

Technical Field

[0001] The utility model relates to the field of stirring devices, in particular to a stirring device for adhesive production. Background Art

[0002] Adhesives are sticky substances that use their adhesive properties to connect two separate materials. A common adhesive is a water-based acrylic composite emulsion, which is stable, durable, and environmentally friendly. It has excellent adhesion and plasticity, and can bond to a variety of substrates. It is suitable for bonding paper, wood, rubber, leather, textiles, and more.

[0003] However, the existing water-based acrylic composite emulsion is composed of acrylic monomers, emulsifiers, initiators and other raw materials, which are basically in the form of powders and aqueous solutions. The existing stirring devices for the production of the mixture basically mix the above raw materials through a stirring rod. However, the powder has a certain viscosity after being exposed to water and is easy to clump. It is difficult to stir it evenly in the later stage, and the finished product after stirring is not ideal.

[0004] Therefore, in order to solve the problem that the aqueous powder is difficult to stir evenly during the production of the above-mentioned adhesive, a stirring device for adhesive production can be designed. Utility Model Content

The distribution assembly, which consists of a drive motor, a threaded rod, and a movable sleeve, drives the scraper to reciprocate, spreading the solid and powdery raw materials on the surface of the screening plate and evenly transporting them downward through the sieve holes of the screening plate.

[0009] In the third step, at the same time, the rotating module drives the stirring plate to rotate at a uniform speed, driving the aqueous raw materials and solid and powdered raw materials inside to flip and fall. The mixture also needs to pass through the beating stick during the discharge process, which further promotes the even distribution of the raw materials and achieves the purpose of uniform mixing;

[0031] See also Figure 5 In this embodiment, a working platform 13 is fixedly connected to the middle position of the inner wall of the mixing barrel 1; a slot 14 is opened on the inner side of the working platform 13, and a front-to-back symmetrical support plate for supporting the slot 14 is fixedly connected to the inner side of the slot 14.
