Described location-plate 312 is fixed on support 301 by hexagon socket head cap screw 318, and its effect is: when the first alignment pin 314 move to contact with location-plate 312 time, no longer continue motion.
Described block 316 is arranged on the end of support 301, its effect is: when the end plate on stripper 308-2 touches block 316, stripper 308-2 is no longer to treating the motion of material direction, and magazine 308-1 continues to treating the motion of material direction, and now stripper 308-2 is by magazine 308-1 bottom lock.
Described electric-control system 4 is made up of detecting element, control element and control box etc., for manual debugging and the operation automatically of package unit.Manual debugging is used for equipment debugging, debugs to the run duration of quantity of graphite, cylinder.Automatic operation is used for normal production.
The utility model is in feeding process, and when cylinder drives feeding rod, hopper to arrive close to dose location, stripper is extracted out automatically from magazine, and graphite being spread distance pipe end in hollow billet is 200 ∽ 300mm places.
The utility model is in feeding process, and when cylinder drive feeding rod, hopper are got back to close to waiting position, stripper self-closed magazine, now graphite is delivered to sub-material mouth by the auger of feeding distribution mechanism just, and graphite falls into hopper from sub-material mouth.
It is as follows that a kind of pierced shell spreads the graphite device course of work automatically:
1. graphite is poured in storage tank 1, opening power and compressed air valve.
2. by the touch-screen of debugging electric-control system 4, adjust the blanking time, spread the amount of graphite and spread the rhythm of graphite, then click " RUN ".
3., when thermoinduction probe 10 shines hot hollow billet 9, hot hollow billet 9 is given in the self-feeding of described feeder 3.
4., when the hopper 3-3 in feeder 3 gets back to start-stop position, the sub-material mouth 2-3 place automatic blanking of feeding distribution mechanism 2, to hopper 3-3, waits for signal next time of popping one's head in.
Operation principle and the course of work of above-mentioned feeder are as follows:
Feeding process: when the piston rod 317 in cylinder 3-1 moves right under the influence of air pressure, with movable slider 304 and the feeding rod 305 that is connected by bulb with it, core bar 313, magazine 308-1, stripper 308-2 simultaneously mobile to feed direction () in figure to the right, when moving to the first alignment pin 314 and touching location-plate 312, core bar 313 drives stripper 308-2 stop motion, feeding rod 305 drives magazine 308-1 to continue to the mobile segment distance (approximating flute length on core bar) of feed direction (right side), now the first alignment pin 314 and the second alignment pin 315 move to the left end of groove, thus stripper 308-2 is extracted out from magazine 308-1, it is 200 ~ 300mm place that the graphite of the inside spreads distance pipe end in hollow billet.
Return process: when cylinder 3-1 is moved to the left under the influence of air pressure, with movable slider 304 and the feeding rod 305 that connected by bulb with it, core bar 313, magazine 308-1, stripper 308-2 is together to treating that material direction () mobile in figure left, when moving to the end plate on stripper 308-2 and touching block 316, stripper 308-2 is no longer to treating the motion of material direction, and magazine 308-1 continues to treating to move a segment distance (approximating flute length on core bar) in material direction, thus by stripper 308-2 by magazine 308-1 bottom lock, now the graphite powder of sub-material mouth falls into hopper 308.
