Abstract
Description
Technical Field
[0001] The utility model relates to the field of pen quality detection, in particular to a pen installation device and a pen detection equipment. Background Art
[0002] A fountain pen is a pen that relies on the close fit between the pen tongue and the nib, and then uses a dropper to inject ink into the hollow pen shaft. Relying on capillary gravity, the ink automatically flows to the nib to achieve the writing effect. It is one of the most widely used writing tools at present.
[0003] In order to detect the smoothness of fountain pen writing, pen manufacturers need to conduct corresponding tests on the pens they produce. At present, the method for testing the smoothness of pens is to fix the pen to be tested, and then make it draw a line on the test paper. The sensor detects the reaction force of the pen on the fixing device during the drawing process, which reflects the size and fluctuation of the friction between the pen tip and the paper. However, this type of equipment is currently used to test gel pens and ballpoint pens, and cannot be used for fountain pens. The specific reasons are:
[0004] The writing principles of fountain pens, gel pens and ballpoint pens are different. The nibs of gel pens and ballpoint pens are thin tubes with steel balls embedded in the tip. The steel balls at the nibs roll out ink to achieve writing. In all directions, the steel balls are in rolling contact with the paper. For fountain pens, the nib is a downward convex arc surface. Under the action of capillaries, the ink flows onto the arc surface. When writing, the nib rubs against the paper and "spreads" the ink on the paper. When people use it, the fountain pen is in a tilted state. The contact point between the nib of the fountain pen and the paper is different for different writing habits and writing strokes.
[0005] Therefore, the current equipment for testing gel pens and ballpoint pens can only test the friction characteristics of a single point, and cannot perform a comprehensive test on fountain pens. Therefore, the current method for testing the fluency of fountain pens is to have qualified personnel write the word "8". During the process of writing the word "8", they experience the feel of each stroke and record or judge the quality of each part of the writing iridium grain of the fountain pen. This testing method cannot quantify the test results of the fluency of the fountain pen, cannot objectively reflect the writing slipperiness of the fountain pen, and cannot effectively distinguish the differences in the quality of the fountain pens.
