[0002] During the preparation process of sealant, the main material and auxiliary materials need to be mixed to improve the wear resistance, viscosity and other parameters of the sealant. In the past, a mixer was used to stir the materials, and various auxiliary materials were added in sequence during the stirring process.

They connect the automatic feeder to the feeding hole on the screw reactor, deliver the materials required for mixing into the screw reactor on time and in quantity, and then mix and output them through the rotation of the screw.

[0004] A screw reaction device with patent number CN217450181U introduces a screw reaction device with a high safety factor. It is found in actual use that because this type of screw reaction device uses a heating rod set on one side, this will cause uneven heat during the stirring operation, resulting in inconsistent parameters of the mixed sealant. In order to solve this problem, a new type of screw reaction device is needed. Utility Model Content
