And then heating (60-120 ℃) for drying and performing high-temperature (130-200 ℃) denaturation treatment to enable the pencil board to reach the softening and easy-to-curl-cut degree. The graphite lead core for processing the lead core is prepared by mixing graphite and clay according to a certain proportion, extruding the lead core with certain specification and size (such as HB-3H lead core diameter of 1.80-2.10 mm) by a core pressing machine after mixing by a kneading machine and a three-roller machine, drying by heating (50-150 ℃) and roasting at high temperature (800-1100 ℃) to ensure that the lead core has certain mechanical strength and hardness, and finally carrying out oil immersion treatment. The color lead is processed similarly to graphite leads, but without sintering. The processing method comprises two methods: one is prepared by mixing clay, talcum powder, adhesive, pigment, oil and wax, molding, and drying; the other method is to mix porcelain clay, talcum powder, pigment and adhesive uniformly and then extrude the mixture into lead core or to put the dried lead core into an oil core container and make the lead core fully absorb grease at a certain temperature, which is called oil immersion method. Processing a pencil plate firstly, splitting and cutting logs into blocks by processing the pencil plate, cutting the blocks into wood blocks by splitting and sawing the blocks, carrying out hydrothermal treatment, then cutting the blocks into the pencil plate by a plate cutting machine, wherein the length of the plate is 184mm, the width of the plate is 73mm, and the thickness of the plate is 4.8-5.2 mm, then using a groove cutting machine to cut the pencil plate into a groove plate with the thickness of 4.1-4.2 mm and a core groove matched with the diameter of a lead core, then using an adhesive to glue the lead core and the pencil plate, heating the groove plate in a clamping state (50-120 ℃) to dry the groove plate for 1-8 hours, and processing the groove plate into a pencil with the length of 178-180 mm by a rod cutting machine. The pen holder of the pencil made by the system is single in primary color, not beautiful and novel, cannot attract user experience, cannot form competitiveness on the market, can increase the manufacturing cost due to paint spraying of extra colors, and cannot be distinguished by the pen holder of a single color if the pencil lead of the pencil is of multiple colors, so that the pencil is not convenient for a user to use.
