S-shaped, therefore, when trip lever 6331 and gathering sill disengage, solve lock slide 623 and reset, slide bar 624 for a pair multiple therewith
Position, one end of a pair brake(-holder) block 622 elasticity connection also resets therewith, a pair brake(-holder) block friction catch brake disc 612 again, and then
Braking rotating seat 611.So far, rotating shaft 41 have rotated 90 degree, and rotating shaft drives intercepter plate 42 rotated ninety degrees, in intercepter plate 42
Heart line and the central axis of discharge pipe 30, mill base can be along discharge pipe 30 output to predetermined station.
4th, when mill base needed for predetermined station reaches scheduled volume, gear pump 10 stops action, the pressure in discharge pipe 30
Reducing, during to certain value, pressure sensor senses, and pressure sensor transmits signal to control system, and control system makes driving fill
Putting action again, repeating above-mentioned third step, under the driving of driving means, rotating shaft 41 drives intercepter plate 42 to rotate along former direction
90 degree, the center line of intercepter plate 42 overlaps with the center line of discharge pipe 30, and discharge pipe 30 is closed by intercepter plate 42, to cut
Only the mill base in discharge pipe continues outwards output under effect of inertia.
Above content is only better embodiment of the present utility model, for those of ordinary skill in the art, according to this
The thought of utility model, all will change in specific embodiments and applications, and this specification content should not be understood
For to restriction of the present utility model.
