The invention relates to the technical field of packing machinery and aims at providing a color pencil packing machine. The color pencil packing machine can achieve the situation that three pencils with different colors are packed in a packing cylinder at the same time and have the advantages of improving the production efficiency and reducing the production cost. According to the technical scheme, a machine for automatic packing multicolor pencils into a cylinder is characterized in that the machine comprises a rack, a feeding device and a feeding and cylinder packing device, wherein the feeding device is used for conveying the pencils and pencil vases through conveyor belts, and the feeding and cylinder packing device is used for pushing the pencils into the pencil vases. The feeding device comprises a rear feeding device body, a left feeding device body, a right feeding device body and a pencil vase feeding device body, wherein the rear feeding device body is located on the rear portion of the feeding and cylinder packing device and used for conveying the pencils with one color, the left and right feeding devices are symmetrically mounted on both sides of the feeding and cylinder packing device and used for conveying the remaining pencils with two other colors respectively, and the pencil vase feeding device body is located on the front portion of the feeding and cylinder packing device and used for conveying the pencil vases. The motion of the conveyor belts is controlled by a stepping motor to ensure the same feeding quantity. Conveyor belt baffles for preventing the pencils from falling down are also disposed on both sides of each conveyor belt in the moving direction.
