Ensure the halted state of eccentric wheel 6.1, the present invention, which puts the quasi- off-position of the quasi- stop sensor, is arranged on eccentric wheel 6.1 by thimble
3.2 drivings are to the position for withstanding flour opening 4.1 completely, i.e., one being horizontally mounted on the backboard 1 by magnetic induction module 9
On plate, when the eccentric wheel 6.1, which is in, drives thimble 3.2 to the state for withstanding flour opening 4.1 completely, the magnetic patch is consolidated
It is scheduled on the eccentric wheel 6.1 and ensures that now magnetic patch is corresponding with magnetic induction module 9, so shuts down or defeated in machine
Go out interval period, no longer leak powder, it is ensured that sealing.
Go out powder drum 2 and the slide rail 3 is connected through a screw thread, go out powder drum 2 and can untie anchor ear and remove at any time, carry out powder storing chamber
4 supply.
Calculate powder outlet quantity：As shown in figure 3, thimble 3.2 is from totally enclosed position a setting in motions, at the same time, connecting rod 7 is pushed up
Circle is drawn in the kinematic pair setting in motion in portion, figure and represents that we are in " one week of gradually closed state between a~b " and " b ' a ' "
Phase accounting is controlled within 5%, and going out deal we are ignored now, and eccentric wheel turns over angle for γ, " b~
C, c '~b ' " deal that goes out in stage is approximately equal to cc ' stage Full-opens.
Separately：" a~c " section eccentric wheels corner is α, if the needle point half-angle of thimble 3.2 is β.
The displacement z of the motion in the vertical direction of the thimble 3.2 of the present invention is hatched area in simple harmonic oscillation, Fig. 4
As actual powder outlet quantity v is the unit time to go out powder speed.
If a cycle T=0.2s, the radius of gyration for the kinematic pair that eccentric wheel 6.1 is connected with connecting rod 7 is
R=7.5mm, the diameter d=0.4mm of flour opening 4.1；Then its powder time that actually goes out is T '=0.19s；
Powder outlet quantity is V=0.19v.Each parameters relationship is as follows：
It the above is only the feature implementation example of the present invention, the scope of the present invention be not limited in any way.It is all to use same
Deng technical scheme formed by exchange or equivalence replacement, all fall within rights protection scope of the present invention.
