The invention discloses color matching material supplying equipment of a cable insulation layer double-color co-extrusion device. The color matching material supplying equipment comprises a base, a vertical column, a lifting column, a cross beam, a pigment extruding device and a pigment supplying device, wherein the vertical column is hollow; the lifting column is inserted into the vertical column; a lifting driving mechanism capable of driving the lifting column to rise and fall is arranged between the vertical column and the lifting column, and comprises a rack fixed on the lifting column and a gear on the vertical column; the cross beam is fixed on the lifting column; the pigment extruding device and the pigment supplying device are fixedly installed on one end of the cross beam, wherein the lifting driving mechanism also comprises a locking screw rod and a locking nut; one end of the locking screw rod is connected to the side wall of the lifting column in a sliding mode, and the other end of the locking screw rod horizontally penetrates through the side wall of the vertical column to be meshed with the locking nut. When the lifting column lifts to the required position relative to the vertical column, an operator rotates the locking nut; the matching of the locking nut and the locking screw rod enables the outer side wall of the lifting column to be closely fitted with the inner side wall of the vertical column so as to prevent the lifting column from sliding relative to the vertical column.
