[0002] Water-based adhesive is an environmentally friendly adhesive that uses water as a medium. It is often used for bonding furniture, flooring, decoration, paper packaging and other fields. Because it does not contain harmful gases and pollutants, it is gaining more and more attention and recognition. Water-based adhesives require the raw materials to be stirred during the production process, so a special stirring device is required.

[0003] In the Chinese utility model patent with the announcement number CN217341009U, a stirring device for the production of water-based paint printing adhesive is disclosed. The device can drive the rotating rod to rotate during the rotation of the stirring shaft through the cooperation of the first bevel gear and the second bevel gear, so that the first stirring blade and the second stirring blade can stir the ingredients at the same time, which improves the stirring efficiency and makes the mixing effect better. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, due to the presence of air inside the mixing barrel and the lack of an integrated structure that can automatically exhaust the air, air is easily mixed into the water-based adhesive during the stirring process, resulting in the appearance of bubbles, thereby reducing the production and processing quality of the water-based adhesive. For this reason, we provide a water-based adhesive stirring device. Utility Model Content
