They are a new generation of commonly used non-toxic and odorless paper-making aids in the world that can greatly improve the dry and wet strength of paper sheets. When in use, the wet strength agent is first poured into a container according to a dosage, diluted 5-10 times with cold water, stirred evenly, and then slowly added to the grinding pond or the pulp pond.

[0003] For example, a liquid mixing device for preparing wet strength agent with the patent number CN215877432U includes a frame, a rotating mechanism and a first stirring mechanism; the rotating mechanism includes a rotating driving part, the rotating driving part is fixedly connected to the frame, the rotating driving part is coaxially fixedly connected with a driving wheel, the driving wheel is drivingly connected with a driven wheel, and the driven wheel is coaxially fixedly connected with the first stirring mechanism. However, the above document still has deficiencies. When in use, the stirring efficiency of the wet strength agent mixture is improved by stirring the wet strength agent mixture in a stirring barrel; in order to achieve the above purpose, the present invention is to set a plurality of blades on the inner wall of the stirring barrel, and drive the stirring barrel and the blades to rotate by a motor, so as to complete the stirring of the wet strength agent mixture in the stirring barrel. However, in the above document, the stirring and mixing only rely on the reciprocating forward and reverse rotation of the power device and the cooperation of multiple blades, and the stirring and mixing effect is poor. At the same time, after the wet strength agent inside the device is discharged after stirring, other equipment needs to be used for quantitative filling, which increases the operation process and is not convenient for quantitatively discharging and filling the wet strength agent inside the device when in use. Content of the Utility Model
