Painting type pens are various painting brushes that are attached to automatic plotters. Common ones are ink pens, ballpoint pens, nylon nibs, ink ballpoint pens, etc. Some plotters are equipped with painting type pens of different widths and colors. Specialized pen for drawing technical drawings. According to the needs of the drawing work, the principle and structure of the fountain pen are used to design and manufacture. There is a water storage structure inside the pen barrel, which can continuously supply water when drawing.
The painting type pens consists of a needle tube tip (point), a pen tip, a water diversion needle, a water reservoir, a connecting screw, a pen tube, a pen holder, a pen sleeve, a compass clip, a bile protection tube, a bushing and a seal. In order to keep the air pressure in the drawing pen water reservoir relatively balanced with the external atmospheric pressure and ensure continuous water supply during drawing, an air intake channel is designed. In order to prevent water leakage caused by sudden changes in external temperature and air pressure, a water storage ring groove is designed. The advanced drawing pen holder has a double sealing structure to prevent the ink from drying out. Drawing pens are divided into two categories according to their uses: manual use and instrument use. The latter includes numerical control plotters, computer-controlled automatic plotters, and computer terminal output record pens, etc.; Wait.
