Principle of Uphill Deduster

Uphill Deduster utilizes an electromagnetic vibrator to vibrate the spiral dedusting body, thus making the tablet to ascend while being polished a dedusted by the vibrating movement. Figure 1 and 2 show more vividly.

In Figure 2, when the electromagnetic coil is charged, the magnetic force (F) would cause the magnet armature to move downward, thus forcing the spring compressed. When the electromagnetic coil is not charged, the magnetic force disappears, and the spring would mover the magnet armature back to its original position. The vibrating motion the machine uses to polish and to dedust is the result from repetition of these movement. In other words, when current situation(I) changes, the magnetic force (F) and the restoring force from the spring (F0, F1, F2) would also change accordingly, which would adjust the movement of the tablet on the spiral dedusting body, and also polish, dedust, and move the tablet upward.

 There are also air powered dedusting device located on the side and roof of dedusting body’s outer cover, which serve the purpose of producing cleaner and smoother tablet.

 There is an empty space, around 1.5mm to 2.5mm, between the upper surface of electromagnetic and the lower surface of the magnet armature. You can see it clearly in Figure 3.
