[0002] Graphene is a two-dimensional carbon nanomaterial with excellent electrical and mechanical properties. It has important application prospects in the fields of energy, medical care, aerospace, etc. Currently, during the preparation process of graphene, it is necessary to add multiple raw materials into the container and mix them evenly, so mixing equipment is needed.

[0003] Existing graphene mixing equipment is usually not equipped with an independent weighing and proportioning mechanism, and only relies on the metering device during the transportation process for proportioning. The impact force during the transportation process and other reasons will inevitably lead to reduced metering accuracy, which in turn leads to an imbalance in the raw material ratio, greatly reducing the accuracy of the formula in the production process. In addition, existing graphene mixing equipment usually relies on complex stirring blades to complete the stirring and mixing of the raw materials. However, when faced with slurry-like raw materials, the stirred raw materials are difficult to remove from the stirring blades, which easily causes waste of raw materials and poor use effect. Existing graphene mixing equipment usually relies on manual cleaning of the mixing barrel, and the cleaning process is complicated and difficult, which greatly reduces the production efficiency. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention

The liquid weighing bin 8 is connected to the second slide 9 only through the weighing sensor 18, so that the weighing sensor 18 can accurately weigh the weight of the liquid weighing bin 8.

[0070] like Figure 1 As shown, a first slide 4 is arranged outside the powder weighing bin 3, and a powder outlet 5 is opened at the bottom of the powder weighing bin 3, and a powder recovery box 6 is arranged below the powder weighing bin 3.

[0071] In a further embodiment, the first slide 4 is slidably connected to the inner wall of the bracket 1, the second slide 9 is slidably connected to the inner wall of the bracket 1, the first slide 4 and the bracket 1 as well as the second slide 9 and the bracket 1 are connected via a first electric push rod 19, and the first electric push rod 19 on the first slide 4 and the first electric push rod 19 on the second slide 9 are staggered to avoid mutual interference between the two first electric push rods 19.

[0072] like Figure 1 As shown, the inside of the powder outlet 5, the inside of the liquid outlet 10 and the discharge port 17 are all equipped with an electric control valve 20, which closes the powder outlet 5, the liquid outlet 10 and the discharge port 17 so that they can be automatically opened or closed when needed.

The fixed partition 21 is connected to the movable platform 141 through a multi-stage hydraulic drive device 24. The stirring rod 145 installed on the outer turntable 143 penetrates the outer partition 22 and is slidably connected to it, and the stirring rod 145 installed on the inner turntable 142 passes through the inner partition 23 and is slidably connected to it. When the multi-stage hydraulic drive device 24 pushes the fixed partition 21, the outer partition 22 and the inner partition 23 on the fixed partition 21 move accordingly. When the fixed partition 21 moves, the outer side of the fixed partition 21 scrapes off the raw materials adhered to the inner wall of the mixing drum 12, and at the same time, the outer partition 22 scrapes off the raw materials adhered to the stirring rod 145 installed on the outer turntable 143, and the inner partition 23 scrapes off the raw materials adhered to the stirring rod 145 installed on the inner turntable 142.

When the ultrasonic module 25 is started, the tool head 26 is driven to vibrate. The shock-absorbing pad 27 can prevent the tool head 26 from colliding with the inner partition 23. At the same time, the shock-absorbing pad 27 can also fill the gap between the inner partition 23 and the tool head 26, so that the raw materials adhered to the surface of the tool head 26 can be scraped off when the inner partition 23 moves.

[0080] In a further embodiment, six connecting gears 144 are provided, and the six connecting gears 144 are distributed in a circular array with the inner turntable 142 as the center.
