Specifically, mixing is to evenly mix graphite powder and binder in a certain proportion to ensure that the formed graphite product has good mechanical properties and accuracy.

[0003] A large amount of dust is generated during the feeding of graphite powder. Manual feeding requires pouring the bagged graphite powder into the mixing cylinder, and workers are prone to inhaling the graphite dust raised during pouring. Moreover, it is not easy for the graphite dust to settle after entering the air. The existing graphite mixing device lacks a device for suppressing the diffusion of graphite dust at the feeding port, which has an adverse impact on the production environment. Summary of the Utility Model

Four corners of the pressing plate respectively extend downward and outward with downward reverse barbs. A grid knife is fixedly connected to the bottom of the dust-proof chamber.

[0006] The environment-friendly graphite mixing device provided by the utility model also has the following technical features:

[0007] Further, the three edges other than the hinge of the top cover extend downward and wrap the three side walls of the dust-proof chamber. The three side walls of the dust-proof chamber are provided with outward inclined cuts.

[0025] In an embodiment of the present application, preferably, the three edges of the top cover 6 other than the hinge extend downward and wrap the three side walls of the dust-proof chamber 5. The three side walls of the dust-proof chamber 5 are provided with outward inclined cuts for hermetically sealing the dust-proof chamber 5. The inclined cuts are convenient for placing the graphite powder packaging bag, as Figure 6 shown.

[0026] In an embodiment of the present application, preferably, an opening and closing type hatch 10 is arranged under the grid knife 9. The hatch 10 is connected to the lid of the mixing cylinder 1 through a spring hinge shaft 11 and is used to open during feeding. After the feeding is completed, it automatically closes under the action of the spring hinge shaft 11 to avoid dust overflow. It should be noted that the spring hinge shaft 11 adopts the structure of the existing technology, and the specific structure will not be described in detail here.

The pressure rod 14 drives the push rod 12, and the push rod 12 pushes the hatch 10 to open. After the top cover 6 is closed, the electric push rod 17 is started to move the pressing plate 7 downward. The reverse ratchet hooks 8 at the four corners of the pressing plate 7 pierce the packaging bag and hook the packaging bag. The pressing plate 7 presses the packaging bag downward. Under the pressure of the pressing plate 7, the grid knife 9 pierces the packaging bag, and the graphite powder flows out. The electric push rod 17 is started to move the pressing plate 7 upward. The reverse ratchet hooks 8 hook up the packaging bag, and the graphite powder falls into the mixing cylinder 1. After the raised dust has settled, the top cover 6 is opened, as Figures 2 - 3As shown, when the top cover 6 is lifted, the hatch 10 is closed under the action of the spring hinge shaft 11. After the top cover 6 is opened, the packaging bag is removed to complete the feeding of graphite powder. By setting a dust-proof chamber 5 at the feeding port 4, the inverted ratchet hook 8 hooks the packaging bag by pressing down the pressing plate 7 in the dust-proof chamber 5, and the packaging bag is cut by the extrusion of the pressing plate 7 and the grid knife 9. When the pressing plate 7 is lifted, the graphite powder falls into the mixing cylinder 1. The whole pouring process is carried out in a closed space to avoid the dust diffusion during the pouring of graphite powder.
