The glass beads replace the original 'steel balls' to be used as ball balls of pen points for production and processing of ball pens.)

1. A ball-point pen uses glass beads (diameter of 0.8mm or less) as a ball at a pen tip. The method is characterized in that: the ball of the pen point is glass micro-beads (the diameter is less than 0.8 mm).

Technical Field

The invention relates to a novel ball-point pen, in particular to a ball-point pen with a pen point and a new material.

Background

The ball of the ball-point pen refers to the ball on the ball-point pen head, the pen head is the key of the ball-point pen, and the pen head is divided into the ball on the pen point and the ball seat body. At present, ball-point pen ball production has high requirements on processing precision and material selection, tungsten carbide ball is widely applied at home and abroad, China has good foundation, and the ball-point pen ball not only can meet domestic production requirements, but also is exported in large quantity. The requirement of foreign production equipment on raw materials is relatively higher, and domestic stainless steel wires cannot be suitable and need to depend on the Japanese imported free-cutting stainless steel wires.

The glass beads mean solid or hollow glass beads having a diameter of several micrometers to several millimeters, and are colorless and colored. Fine beads having a diameter of 0.8mm or more; beads having a diameter of 0.8mm or less are referred to as microbeads. The glass bead is a novel silicate material and has the characteristics of transparency, adjustable refractive index, directional retro-reflection, smooth surface, good fluidity, electric insulation, stable chemical performance, heat resistance, high mechanical strength and the like. The high-strength solid micro-beads are mainly used as grinding media, grinding materials for machining, reinforcing fillers and the like, and the light-reflecting solid micro-beads are mainly used for traffic signs, art and propaganda advertisements, life saving equipment on the sea, performance clothing, directional projection screens and the like. The glass beads have different chemical compositions depending on the application, and the common compositions include soda-lime glass, borosilicate glass, zirconium-containing glass, titanium-containing glass, high silica glass and the like.

Disclosure of Invention

In order to solve the problems of high processing difficulty and high requirement on raw materials of the existing ball-point pen, the invention provides a technical scheme for replacing the existing 'steel ball' with glass beads, thereby reducing the production and processing difficulty of the ball-point pen and the high requirement on raw material selection.

The technical scheme adopted by the invention is as follows: the glass beads which meet the requirements (including the diameter range, whether the glass beads are perfect circles, the surface smoothness and the like) are obtained by strictly screening the produced glass beads. The production and processing of the ball-point pen are carried out by replacing the original 'steel ball' (the ball in the attached drawing of the specification) with glass beads as the ball of the pen point.

Compared with the prior steel ball, the invention has the advantages that the production and processing difficulty of the glass beads is greatly reduced, and the requirement on raw materials is also greatly reduced. The surface of the glass bead is smoother, the hardness is higher, and the wear resistance is better. The glass beads can transmit light, change color and are easier to increase commercial application and commercial value.

Drawings

The present invention will be described in detail below with reference to the accompanying drawings so that the above advantages of the present invention will be more apparent. FIG. 1 is a cross-sectional view of a ballpoint pen tip according to an embodiment of the present invention.

Detailed Description

The raw materials are prepared according to the requirements of ball-point pens (hardness, color and the like of the ball), then the production is carried out, and the produced glass beads are strictly screened according to the requirements of ball-point pens (including diameter range, whether the ball is perfect, surface smoothness and the like). And replacing the original 'steel ball' with the screened glass micro-beads meeting the requirements to serve as the ball of the pen point for producing and processing the ball pen.
