Description

Refill head collision testing mechanism of ball pen

Technical Field

The utility model belongs to the technical field of the technique that detects is relevant and specifically relates to a refill head collision test mechanism of ballpoint pen.

Background

A ball point Pen (Ballpoint Pen) is a Pen that brings out a writing medium by rolling a ball at the tip of a Pen or a refill, and is a Pen using a minute rotary ball made of brass, steel, or tungsten carbide that releases ink onto paper at the time of writing. Ball-point pens are very different from the reed pens, feather pens, metal nib pens and fountain pens of its predecessors. The writing principle of ball-point pen is mainly characterized by that when the ball is directly contacted with paper surface to produce friction force, the ball can be rolled in the ball seat to bring out ink or ink in the pen core so as to attain the goal of writing. A ball-point pen is a pen which writes with ink mixed with different pigments. The pen point is a small steel ball, the small steel ball is embedded into a small cylinder-shaped copper bowl, a plastic pipe filled with printing ink is connected behind the small steel ball, and the printing ink flows down from the periphery along with the rotation of the steel ball.

Ball-point pens are of various types and styles, and have different grades such as high, medium, and low in terms of quality, but they are basically classified into oil-based ball-point pens and water-based ball-point pens. The oil-based ball-point pen is commonly called a ball-point pen. The ball of the pen point is made of stainless steel or hard alloy materials. The size of the ball diameter determines the thickness of the handwriting line. The common ball-point diameters are 1 mm, 0.7 mm and 0.5 mm (the pen body or the ball-point pen core of the product is usually noted). The ink for ball-point pen is specially made, and is mainly made up by mixing colour material, solvent and viscosity-regulating agent. The common colors are blue, black and red. Ordinary ink is used for ordinary writing, and special ink is used for archival writing.

The oil-based ball-point pen is the first generation of ball-point pen series products, and has been put on the market in bulk for over 60 years. The oil ball pen is improved and perfected for a long time, the production process of the oil ball pen is mature, the product performance is stable, the storage period is long, the writing performance is stable, the oil ball pen is a traditional product variety in ball pen products, and the viscosity of ink used by the oil ball pen is high, so that the writing hand feeling is relatively heavy.

And the water-based ball-point pen is also called a ball-point pen or a ball-point pen. The pen holder and the pen cap of the pearl pen are all plastic pearl pens formed by plastic injection molding; the pen cap is a half-steel ball-point pen made of stainless steel through stamping and grinding; the pen holder and the pen cap are all made of stainless steel, so the pen is called a full-steel ball-point pen. The all-plastic type is basically disposable, namely the ink is discarded after being used up; the semi-steel type and the full-steel type mostly adopt a replaceable pen core type structure. The pen point of the ball pen is divided into a cannonball type pen point and a needle tube type pen point, and the two pen points are respectively made of copper alloy, stainless steel or engineering plastics. The ball is made of stainless steel, hard alloy or alumina and other materials, the diameter of the middle writing ball is 0.7 mm, and the diameter of the fine writing ball is 0.5 mm. The water storage form is divided into a fiber bundle water storage form and a fiber bundle-free water storage form. The color of the ink is red, blue, black, green, etc. The ball pen has the characteristics of a pen and an oil ball pen, is smooth in writing and uniform in lines, and is an ideal writing tool.

The ball-point pen has the advantages of simple structure, convenient carrying, writing lubrication, suitability for duplicating and the like, and is popular among students in schools, clerks in office buildings and other people in all the world. The ball-point pen is different from fountain pen in that it uses dry ink which is carried out by the freely rotating steel ball on the pen head and then transferred to paper, so it has no leakage, is not affected by weather, and has long writing time and no need of filling ink.

The ballpoint pen need test the refill head at production process, see whether refill head and refill install firmly up to standard, nevertheless adopt artifical manual mode to the most adoption of the firm collision detection that falls of refill head installation on the existing market, highly fall from about with the pen, then whether the inspection refill damages, such mode is too coarse, does not consider the angle and the height that the pen falls, detects the nonstandard.
