Abstract

The invention discloses a manufacturing process of an environment-friendly pencil. The manufacturing process comprises the three main body steps of forming preparation of a pencil rod plate, a pencilcore containing processing and polishing and cutting forming. According to the technical scheme, useless plant straws and leaves are collected and crushed into powder through a pulverizer, the water content of the powder reaches 3%-5% through high-temperature heating and drying treatment, then high-temperature compression molding is carried out on the mixing material, and a filling agent is addedto cooperate with a natural glutinous rice adhesive, and therefore, the problem of holding hand feeling and pencil rod hardness of a pencil rod can be effectively solved, then the surface of the pencil rod is not prone to falling off and is not prone to breaking, moreover, waste of other resources in the production process of the pencil is greatly reduced, and the purpose of saving energy is achieved; and the environment-friendly effect is remarkable, so that the method is worthy of large-scale industrial popularization.

Description

technical field [0001] The invention relates to the technical field of pencil manufacturing technology, more specifically, the invention relates to a new and improved manufacturing technology of environmentally friendly pencils. Background technique [0002] Pencil (Pencil) is a special type of pen used for writing and drawing sketches. It has a history of more than 400 years. Penholders, pencils with caps; at the same time, in order to meet the needs of different writing or painting colors, the color of the pencil lead is not limited to the pure graphite black primary color. Manufacturers can choose different materials and pigments for the pencil lead according to different needs. Get different writing or drawing colors. [0003] The penholder of wrapping pen lead in the pencil on the market at present, the overwhelming majority all all is processed with raw wood raw material. As we all know, raw wood is a precious resource of the country, and it is also a material in sho...
