Abstract

The invention discloses an environment-friendly wood-like pencil plastic preparation process, and relates to the technical field of pencil manufacturing and processing. The environment-friendly wood-like pencil plastic preparation process comprises the following steps that (1) refill granulation is carried out; (2) pencil skin granulation is carried out; (3) pencil holder granulation is carried out (4) wire pulling is carried out; (5) cutting polishing is carried out; (6) eraser head assembling is carried out; (7) trademark printing is carried out; (8) sharpening is carried out; (9) cleaning is carried out; and (10) packaging is carried out. A plastic pencil proposed by the invention is proper in material selection and reasonable in formula, the produced pencil is exquisite in appearance,free of refill leaning, free of refill breaking, moderate in rolling and cutting hardness, smooth in writing and strong in coloring, plastic is used for replacing wood, a large amount of wood is saved, and the national forest resources and ecological environments are reasonably and effectively protected.

Description

Technical field: [0001] The invention relates to the technical field of pencil manufacturing and processing, in particular to a preparation process of an environment-friendly imitation wood plastic pencil. Background technique: [0002] Pencil is a kind of cultural school article commonly used by people, is mainly used in aspects such as writing and drawing. Its main structure is composed of a strip of lead embedded in the pen holder. Generally, the pen holder of a pencil is usually made of wood. When making it, it is usually necessary to make the log into a pen holder in the shape of a circle, a regular hexagon, or a regular octagon. High, and consume a lot of high-quality wood. At present, my country's annual output of wooden pencils is about 8 billion, which is equivalent to destroying 600 square kilometers of forest every year and consuming 400,000 cubic meters of high-quality wood. The consumption of a large amount of forest resources has seriously damaged the ecologi...
