Carbon pen and manufacturing method thereof

Abstract

The invention discloses a carbon pen. The carbon pen comprises a wood penholder and a carbon cartridge inside the wood penholder, wherein a glue layer is arranged between the wood penholder and the carbon cartridge, and a resin protection layer is further arranged between the outer surface of the carbon cartridge and the glue layer. The invention further discloses a manufacturing method of the carbon pen, wherein a coating step is added before the core gluing method is conducted. Before the carbon pen is manufactured, the resin protection layer is formed on the surface of the carbon cartridge so that the cartridge can be well isolated from glue, meanwhile, the PVAC glue is adopted in the core gluing step, the binding force between the carbon cartridge and wood panels is reduced on the premise that the binding force between the wood panels is ensured, and therefore the cartridge can be effectively prevented from being broken in the peeling process, and product quality of the carbon pen is improved.

Description

technical field [0001] The invention relates to a stationery product, in particular to a carbon pen and a preparation method thereof. Background technique [0002] Carbon pens are composed of carbon refills and wood pen holders. Since the carbon refills themselves do not contain paraffin, stearic acid and other components, they are brittle and easy to break. [0003] In the production process, the carbon pen needs to go through the steps of grooving, rubber core, beam clip and planing rod, as follows: [0004] Grooving step: dig out grooves on the wooden board; [0005] Rubber core step: Spray glue in the slot and put in carbon refill; [0006] Clamping step: Glue two wooden boards together, the carbon pen core is clamped in it, clamp and fix the two wooden boards with clips, and place them for a period of time; [0007] Planing rod step: Use a machine to plan out the wooden boards after the bundles to become individual carbon pens. [0008] In order to avoid slipping th...

AI Technical Summary

Problems solved by technology

[0008] In order to avoid slipping the core, EVA glue will be used as the glue for the rubber core to firmly stick the carbon core to the wood pen holder. Although this solves the problem of slipping the core, it will bring difficulties to the curling. The core sticks very well. When the wood on the wood pen barrel is chipped off, it is easy to break the carbon core inside.
