[0014] This application also discloses a production method for the graphite anode material of new energy lithium batteries. The method includes the following steps;
[0015] Step 1: During production, start the first motor and the second motor. The output end of the first motor drives the first spiral roller to rotate. The rotation of the first spiral roller drives the first driving wheel to rotate. The rotation of the first driving wheel drives the first driven wheel to rotate through the first belt.

[0019] 2. In the present invention, when the discharge tray on the conveyor belt rotates to the lower part, the ejector rod contacts the surface of the inclined plate, pushing the push plate to move. The push plate pushes the material in the discharge tray out for demolding, and then drives the push plate to reset through the spring, avoiding the problem of poor demolding after shaping.
[0020] 3. In the present invention, the rotation of the first spiral roller drives the first driving wheel to rotate. The rotation of the first driving wheel drives the first driven wheel to rotate through the first belt. The rotation of the first driven wheel drives the second spiral roller to rotate.
