The pouring sealant is mainly used in electronic products and electric appliances, so that the quality requirement on the pouring sealant is extremely high, most users tend to purchase high-quality products, the performance of the pouring sealant is guaranteed after solidification, and the performance and the public praise of the electric appliances can be improved. However, the stirring process in the construction process is usually ignored, and the final film forming effect is still affected due to unqualified stirring process. The pouring sealant needs to stir the AB component respectively during construction, then the A component is poured into the B component for stirring, and the stirred pouring sealant raw materials are not easy to precipitate and can be uniformly dispersed in the glue solution. In construction, the AB components are not fully and uniformly stirred for mixing due to construction period or other reasons, but the situation is not known that the raw materials in the glue solution are precipitated during storage, the hardness is easy to change after mixing and curing, and the performance of the cured product is layered up and down and even changed. This is particularly the case, which is difficult to find after curing, which results in a large number of rejects, and the public praise of the appliances is also reduced, with a considerable safety risk if such products are introduced into the market. Therefore, although the quality of the product is really concerned when the pouring sealant is purchased for customers, the construction process is emphasized, the stirring of the pouring sealant at present is divided into manual stirring and mechanical stirring, the stirring with larger mixing amount at present is concerned more, mechanical stirring (bench drill and hand drill) is adopted when the mixing amount is larger, and the prior art generally comprises: the stirring head of the stirrer is arranged at a slightly deviated position of the stirring center and is preferably arranged at a depth of about half to two thirds below the liquid level, the rotating speed is 700 revolutions per minute, and the stirring time is about 3-5 minutes. For the case where the mixing amount is not large, the prior art is: the stirring rod is manually used, and the stirring rod is tightly attached to the side wall and the bottom of the cup to stir during stirring so as to prevent the glue solution on the side wall and the bottom wall of the beaker from being mixed and solidified insufficiently, the stirring speed cannot be too slow, and the stirring time is generally 5 minutes. At present, the cost factor is considered for the condition of stirring with small mixing amount, so the prior art does not adopt mechanical stirring, but if a device with simple structure can be arranged to replace manual stirring, the requirement of stirring with small mixing amount can be better realized. Patent publication No. CN 204261606U: the special planetary wall scraping stirrer for the surface treatment of the filling powder of the electronic pouring sealant is characterized by comprising a frame, a motor, a belt transmission mechanism, a planetary gear transmission mechanism, a stirring mechanism, a charging barrel and an annular sealing ring; the motor is arranged on the frame and transmits power to the planetary gear transmission mechanism through the belt transmission mechanism; an annular gap is formed in the bottom of the charging barrel, and an annular sealing ring is inlaid in the annular gap; the planetary gear transmission mechanism comprises an input shaft, a gear set and a planet carrier, wherein the gear set comprises a planetary gear, the input shaft is a power input shaft of the planetary gear transmission mechanism, and the gear set is installed on the input shaft to rotate through a bearing; the gear set transmits power to the planet carrier through gear engagement, and the planet gears on the planet carrier revolve along with the planet carrier and simultaneously do autorotation.
