Manufacturing method for finger joint pencil and finger joint pencil

Abstract

The invention discloses a manufacturing method for a finger joint pencil, and relates to the technical field of pencil processing. The manufacturing method comprises: S1, obtaining a plurality of pencil plates, and dyeing the plurality of pencil plates with different or same colors according to preset requirements; S2, forming an upper processing groove and a lower processing groove; S3, forming a plurality of oblique cone grooves and oblique cone-shaped finger-shaped tenons; S4, selecting any two pencil plates for joining to form finger joint plates and finger joint lines; S5, cutting off protruding parts of the top and bottom faces of the finger joint plates; S6, forming a plurality of core grooves in the top faces of the finger joint plates; S7, gluing lead cores into the two finger joint plates to form a forming plate; and S8, performing rod planing on the forming plate to form a plurality of pencil rods are formed, each pencil rod comprising a first pencil plate color, a second pencil plate color and finger joint lines. A finger joint pencil is further disclosed. The manufacturing method for the finger joint pencil has the advantages of being low in manufacturing cost, high in manufacturing precision and capable of manufacturing new types of pencils.

Description

technical field [0001] The invention relates to the technical field of pencil processing, in particular to a method for making a finger-joint pencil and the finger-joint pencil. Background technique [0002] Pencil is a kind of pen used for writing and drawing and sketching. It has a history of more than 400 years. Among them, pencils for drawing and sketching are divided into many types. It is divided into three stages of development, divided into graphite, wood It is used to make pen holders and capped pencils; in addition, its colors are red and white, black and white, yellow and black and other stripes. After heating (60-120° C.) drying and high-temperature (130-200° C.) denaturation treatment, the pencil board is softened and easy to curl. Lead core processing graphite lead core is prepared by mixing graphite and clay in a certain proportion. After kneading machine and three-roll machine are mixed, a certain size is extruded through a core press machine (such as HB~3H ...

AI Technical Summary

Problems solved by technology

The primary color of the penholder of the pencil made by the above method is single, unattractive and novel, cannot attract user experience, and cannot form competitiveness in the market. The paint spraying of additional colors will increase the manufacturing cost. , can not rely on a single color pen barrel to distinguish, which is not convenient for users to use
