Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pencil lead processing, in particular to a graphite lead processing device. Background Art
[0002] Graphite lead is the core part of the pencil, mainly made of powdered graphite and a binder. The production process of pencil lead includes mixing graphite powder and a binder, and then forming it by extrusion or extrusion. The softer graphite lead strips are then cut according to production requirements, and then dried and hardened to form a solid lead. Finally, the lead is painted to become a finished pencil lead.
[0003] During the extrusion or forming stage, the staff will reel the continuously extruded slender lead core onto the take-up wheel, then place the take-up wheel on the operating table, use a core cutter to cut off all the graphite lead cores rolled up on the take-up wheel, then slowly rotate the take-up wheel to spread multiple graphite lead cores flat on the operating table, then use a ruler to measure the distance to be cut and then use a core cutter to cut multiple graphite lead cores.
[0004] The staff usually holds the ruler in one hand and the core cutter in the other hand. Such operation often causes the cutting position to be offset and is very demanding on the staff's cutting skills. If they are not careful, the lead core may be cut crooked, resulting in the length of the cut lead or the cut surface of the lead core not being flat enough, which in turn causes the cut lead core to fail to meet the subsequent production requirements. To this end, we propose a processing device for graphite lead cores. Utility Model Content
