The width on the large end inclined-plane of described voussoir is greater than the width of pressurize slide block 8.
The width of described straight-bar is less than gap original between two pieces of slide blocks 5.
Working principle of the present utility model:
The utility model realizes the clamping of brake block, and the insulation of brake block, pressurize and brake block unclamp a continuous print action.
1, the clamping of brake block:
Position limit cycle 1, slide block 5, spring 6, spring pedestal 7, pressurize spring 9 are installed on base 13, base plate 13 is arranged on conveyor belt 2, slide block 5, spring 6, spring pedestal 7, pressurize spring 9 are in position limit cycle 1, brake block 12 is placed between spring pedestal 7 and position limit cycle 1, during original state, spring 6 is in former long status, and pressurize spring 9 is in compressive state due to the spacing of slide block 5, leaves gap between brake block 12 and spring pedestal 7.Motor drives conveyor belt 2 to drive base plate 13 to run forward, when slide block 5 enters immediately below gripping cams 3, the gripping cams 3 of motor drive cam shaft makes clamping push rod 4 start lifting movement, namely clamps push rod 4 and starts to move downward, and the voussoir on clamping push rod 4 starts to promote slide block 5 and moves.When having gap when between spring pedestal 7 and brake block 12, slide block 5, spring pedestal 7 move together, and after spring pedestal 7 contacts with brake block 12, slide block 5 still promotes lower slider at voussoir, and then Compress Spring 6, realizes the pinching action of brake block 12.
2, the insulation of brake block, pressurize:
When clamping push rod 4 drops to lowermost end, slide block 5 middle is positioned at immediately below gripping cams 3, and slide block 5 moves to limit position, and now spring 6 decrement reaches maximum.Clamp push rod 4 speed simultaneously and be reduced to zero, and contact with pressurize slide block 8, pressurize slide block 8 is owing to losing the spacing of slide block 5, under the effect of pressurize spring 9 being in compressive state, move upward together with clamping push rod 4, and replace the voussoir restriction slide block 5 on clamping push rod 4, and then the pressurize action completed brake block 12, when slide block 5 leaves immediately below gripping cams 3, clamping push rod 4 completes backhaul action, by conveyor belt 2, base plate 13 is sent into thermostat 17 afterwards.
3, brake block unclamps:
Complete and the insulation of brake block 12 is operated, base plate 13 is under conveyor belt 2 drives, leave thermostat 17, when slide block 5 enter unclamp immediately below cam 10 time, the cam 10 that unclamps of motor driving cam ejector rob axis makes to unclamp push rod 11 and starts to move downward, after moving to certain position, unclamp push rod 11 to contact with pressurize slide block 8, and promote pressurize slide block 8 and move downward, when slide block 5 be in unclamp immediately below cam 10 time, unclamp push rod 11 and move to lowermost end, slide block 5 is owing to losing the restriction of pressurize slide block 8, under the effect of spring 6 restoring force, get back to initial position, what realize brake block 12 unclamps action, when slide block 5 leave unclamp immediately below cam 10 time, unclamp push rod 11 and complete backhaul action.
