Feeding device and electrode bar sorting machine

The electrode bar sorting machine comprises a clamping device, a detecting device and a material distributing frame, the feeding device comprises a shell and a pushing body, the shell is provided with a material bin used for storing cylinders, the material bin is provided with a first inclined face, the first inclined face inclines upwards in the outward extending direction, and the pushing body is arranged on the first inclined face. The pushing body can extend into the stock bin, when the pushing body moves in the first direction, the pushing body is attached to the first inclined face, and meanwhile the pushing body moves the multiple columns in the stock bin out of any column. The pushing body moves the multiple cylinders in the stock bin out of any cylinder, the clamping device can be used for clamping one cylinder moved out by the pushing body and moving the cylinder to the detection device, the detection device is used for detecting the resistance value of the cylinders, the material distribution frame
