Principle of work of the present utility model:
Consult shown in Figure 10ly, transmitting working order with the pressing of a single station detonator dress is example:
Initial state; Coaster 4 waits for that at the preceding explosion-proof inlet end that transmits tube 3 the explosion-proof gate 2 of inlet end is in unlatching, and the explosion-proof gate 6 of exit end is in closes; Coaster 13 is the explosion-proof inlet end wait that transmits tube 10 in the back, and the explosion-proof lock 11 of inlet end is in closes, and the explosion-proof lock 14 of exit end is in unlatching; The mould 7 that cap shell is housed is pushed in the coaster 4 by linear reciprocation cylinder 5; Traction control mechanism 1 receives the initiating signal forward rotation, and the traction rope 19 long distance of L of advancing clockwise drives coaster 4 and the coaster 13 long distance of L of advancing simultaneously, each explosion-proof lock displacement, and promptly former opened condition becomes closes, and former closing condition becomes unlatching.Linear reciprocation cylinder 8 is received initiating signal, pushes ahead, and the mould on the coaster 47 is pushed in the charge machine 9, and the mould of depositing before in the charge machine 9 ejected enter in the explosion-proof coaster 13 that transmits tube 10 in back, and this moment, transport unit was in reduced state.
Reduced state; Start traction control mechanism 1 backward rotation, the traction rope 19 long distance of L of advancing counterclockwise drives coaster 4, the 13 long distance of L of advancing simultaneously, and each explosion-proof lock is shifted once more.Charge machine 9 is received the initiating signal that transmits after explosion- proof gate 2,11 resets, and carries out charging, because coaster operation required time is far longer than the time that explosion-proof lock resets, so charge machine 9 work and coaster 4,13 motions almost can be carried out simultaneously.When the current explosion-proof explosion-proof coaster 13 that transmits in the tube 10 of coaster 4 and back that transmits in the tube 3 arrives inlet end 2 and exit end 14 respectively, coaster 4 instruction reciprocating air cylinders 5 repeat aforesaid operations, 13 instructions of coaster reciprocating air cylinder 12 is started working, mould on the coaster 13 is pushed ahead, be pushed into by slide rail 15 in the explosion-proof vent of next station.The rest may be inferred, goes round and begins again, and can realize easily that multi-work-station transmits hazardous substance continuously.
