Problems solved by technology

[0003] However, when the existing marker pens are regenerated and processed, the structural strength of the pen core cannot be guaranteed, so it is easy to bend and deform during use, which will affect the ink output of the pen tip, and the adaptability is poor, and it cannot be guaranteed during production. The amount of ink perfusion, if the amount is small, will affect the service life and reduce the quality of the product, but if the amount is too large, it will overflow from the inside of the pen holder, and then pollute the canvas, etc. The effect is not ideal, so a new production process needs to be proposed

Abstract

The invention discloses a manufacturing process of a marker pen. The manufacturing process includes the following steps that P1, injection molding is performed by using an injection mold, and a pen barrel and a pen cap are processed; P2, a core cotton is manufactured by adopting acrylic fiber, and a polyester material is wrapped to form a wrapped barrel to make a refill; P3, ink is infused insidethe refill; P4, a pen tip and the refill are mounted, the pen barrel is sealed, and the pen cap is closed; and P5, inspection and packaging are performed, the packaging is performed inside a pen box,and then the marker pen is manufactured. By using the acrylic fiber to make a cotton sliver board, and then cutting and curling are performed to form a cotton barrel, generation and processing can beperformed according to different specifications to facilitate control, a thin steel wire is embedded inside to make a refill structure to ensure the stable refill, the coming out of ink is not affected, during ink perfusion, the mode of natural infiltration is performed for full absorption, then extrusion control is performed, this way, generative convenience and using stability of the marker pencan be greatly improved, and the using effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of marker pens, in particular to a manufacturing process of marker pens. Background technique [0002] A marker pen, also known as a marker pen or a marker pen, includes a pen holder and a refill inside the pen holder. The front end of the pen holder is provided with a pen tip inserted into the inner refill. It is a special drawing color pen for writing or painting. Use is very common. [0003] However, when the existing marker pens are regenerated and processed, the structural strength of the pen core cannot be guaranteed, so it is easy to bend and deform during use, which will affect the ink output of the pen tip, and the adaptability is poor, and it cannot be guaranteed during production. The amount of ink perfusion, if the amount is small, will affect the service life and reduce the quality of the product. If the amount is too large, it will overflow from the inside of the pen holder, and then pollute t...
