The needle pipe is also known as drawing ink pen. It is a tool specialized in drawing ink line drawings. It can draw a precise and similar width lines.The size of the needle pipe diameter of the needle pipe determines the width of the lines drawn.There are different thickness of the needle pipe pen, and the needle pipe diameter has a different specifications of 2.0mm from 0.1 to a one -time pipe pen tip (to show differences). In the design drawing, at least three different thickness, middle, and thick thickness should be prepared in the design drawing diagramPen pen.Another disposable pipe, also known as sketch pen, see the picture on the right, not within the scope of the discussion below.(At the end of the pen tip is the nylon stick instead of steel needles, and there is no heavy hammer in the shaking.) Let ’s introduce it in detail below!
The structure and principle of stationery needle pipe pens
The ink of the needle pipe flows out of the tube is the result of air pressure and gravity.The air entering the pen tube comes from the pen tip during the pen.Small bubbles float into the pen tube, and then pressed on the ink.The ventilation in the pen tip composition makes the air pressure in the pen tube be flat, so it can keep the ink flow evenly.If the airway is blocked, the bubbles cannot enter, and the ink cannot flow out.The block is because the pen is vibrated, which makes the air expand, which makes the ink enter the vent.In the tube pen tip is a thin metal wire tied to a heavy object. This is the only motion part in the pipe pen. When the pipe is tilted or vibrated, the gravity moves the metal wire up and down, controls the outflow of ink, and removes the tip of the pen tip.Any small debris.
Using stationery needle pipe pens and maintenance
Good maintenance is the key to extending the life expectancy.If the pen is used every day or every week, the ink is usually not dry, and the pen can also be in a good state.If two weeks, or even put it on the spot, the ink may be dried in the pen.At this time, you must clean it up, even so, you may not be able to use it.
Maintenance suggestions:
(1) If you need to use it every day or every two months every day.When you dont know how long it will take, you should clean it first.If you wash and use a pen every week, the trouble is much less.
(2) Pay attention to the sound of the needle.The needle tied to heavy objects is the only mobilized part of the needle pipe pen.When you shake the pen or work normally, the heavy object knocks out.No sound, indicating that the needle is bent or the ink is dry, so that the heavy objects are fixed, or the heavy objects have been disconnected with the needle.
Precautions for use
(1) When drawing lines, the needle can be kept perpendicular to the paper surface as much as possible to ensure that the lines with uniform thickness are drawn.
(2) The order of the drawing of the pipe pen should be based on the principles of first, then, then left, left, back, right, first, then straight, first, then thin and thick.
(3) When the stroke is used as a picture, the pen and the pen should not be paused.
(4) In addition to using a straight segment, the pipe pen can also be connected to the circular or arc lines with the accessories of the round regulations and the circular regulations.
(5) Usually, it is advisable to use and maintain the needle pipe to ensure a good working state and long service life in the pipe pen.When not in use, you should put a pen hat at any time to avoid drying the needle tip ink, and should be cleaned regularly to keep the pen smooth.
