On.
Operation principle: being placed on by chalk on charging housing 166, then cover lid, now, the dust on chalk drops
On the bottom surface that groove 11 placed by chalk, run by ventilation blower 14, it is achieved air-breathing so that it is recessed that dust is entered collection by through hole 12
In groove 23, subsequently in collecting tank 242, after accumulating certain dust, firmly pull downward on collection lid 24 and i.e. can be taken off toppling over, non-
The most convenient.
And take chalk time, by pressing the button on control chamber 4 so that promote cylinder 162 push rod promote so that powder
The mobile rear to push pedal 113 of pen, then, the push rod of discharging cylinder 112 promotes so that chalk stretches out from discharging opening 111, convenient
Manually take.
Wherein, when promoting the promotion of cylinder 162, moving stop 167 blocks charging groove 165, prevents follow-up chalk
Falling, until promoting the push rod retraction of cylinder 162, moving stop 167 return, now chalk is dropped into for 165 from charging groove
Enter chalk and place in groove 11, it is achieved follow-up discharging.
