(as Figure 1 and Figure 4) is installed respectively with two layback axis 45 and is fixed on three-level gear wheel 48 and cam 58, and two
A 45 position of layback axis is coaxial, is separately fixed on left wall plate 1 and right wall plate 2 with two end axis 57, and two ends, 57 position of axis is same
Axis installs positioning with two end axis 57 respectively with two leading arms 54, and the lower end of two leading arms 54 is installed on last item 32 respectively
On, the both ends that last item 32 stretches out left wall plate 1 and right wall plate 2 are located in, use two torque arm axis respectively with one end of two torque arm 49
Pin 53 is installed on two leading arms 54, the other end of two torque arm 49 respectively with the end axis on cam 58 and three-level gear wheel 48
57 install positioning.
Spring operating mechanism working method of the present invention:
Thermal energy storage process: (as shown in Figure 1, Figure 3) motor 27 is powered, and passes through motor gear 27, level-one gear wheel 57, level-one tooth
Wheel shaft 26, second level Large Gear Shaft 77, secondary gear wheel shaft 25, the cooperation transmission of three-level gear wheel 48, form three-level deceleration mechanism, make three
Grade gear wheel 48 drives energy storage axle 24 to rotate counterclockwise.Two layback axis 45 on three-level gear wheel 48 and cam 58 are with energy storage axle
24 rotations, two layback axis 45 drive two torque arm, 49, two leading arms 54 and last item 32 to be moved to the left, compress switching-in spring
30.27 power supply of circuitry cuts motor is controlled when the last one tooth before three-level gear wheel 48 turns to oscillating tooth 52, three-level is big at this time
Gear 48 can be hauled by switching-in spring 30 and be rotated counterclockwise, when the locking roller 47 and second level closing pawl on three-level gear wheel 48
Bevel edge on 42 is bonded, and the roller A41 on second level closing pawl 42 is withstood by the section of sincere sub 40 top of level-one separating brake, and three-level is big
The rotation of gear 48 is led by card, and 30 elastic force potential energy of switching-in spring is locked, to complete thermal energy storage process.
It has rotary inertia after 27 dump of motor to continue to rotate, but be lockable can not be after for three-level gear wheel 48
Continuous to rotate, the oscillating tooth 52 on three-level gear wheel 48 can make secondary gear axis 25, one-stage gear axis 26 at torsional spring C50 and cooperation
It is continued to rotate with motor 27, until motor 27 and each gear oneself stop.
Making process: (as shown in Figure 5) switching electromagnet 37 strikes 40 lower end of level-one closing pawl after being powered, and closes level-one
Lock sincere sub 40 rotates counterclockwise, and the roller A41 on second level closing pawl 42 is detached from level-one closing pawl 40, second level closing pawl 42
The promotion of roller 47 is blocked to rotate counterclockwise, under the elastic force potential energy effect of switching-in spring 30, two leading arms 54 and two drawings
Arm 49 drives three-level gear wheel 48 and energy storage axle 24 quickly to rotate counterclockwise.(as shown in Figure 4) cam 58 is quick with energy storage axle 24
Rotation, cam 58 hit and drive 61 quick rotation of combined floodgate roller, and under the effect of cam 58, transmission crank arm 59 quickly turns counterclockwise
Dynamic until cam 58 is detached from combined floodgate roller 61, transmission crank arm 59, which is rotated, to be rotated to compress tripping spring 5 with interior connecting lever 22, is passed
Separating brake roller 60 when dynamic 59 quick rotation counterclockwise of connecting lever thereon pushes sincere sub 72 left end of level Four separating brake to move up, separating brake rolling
After son 60 is detached from sincere sub 72 left end of level Four separating brake, level Four separating brake sincere sub 72 moves down reset in left end under torsional spring E70 effect,
(as shown in Figure 6) level Four separating brake is sincere sub 72, three-level separating brake is sincere sub 73, second level separating brake sincere sub 68 and the sincere sub 65 phase interworking of level-one separating brake
It closes the main separating brake roller 60 of card and transmission crank arm 59, the elastic force potential energy of tripping spring 5 is lockable.33 turns of output toggle arm on output shaft 23
It is dynamic that switch is driven to complete feed motion.
Separating brake process: (as shown in Figure 6) tripping electromagnet 62 strikes level-one separating brake sincere sub 65, the sincere son of level-one separating brake after being powered
65 rotate clockwise, and so that the roller B69 on second level separating brake sincere sub 68 is detached from level-one separating brake sincere sub 62, in the elastic force of tripping spring 5
Under potential energy effect, roller C71 is detached from second level separating brake sincere sub 68, and separating brake roller 60 is detached from level Four separating brake sincere sub 72, and second level separating brake is sincere
Son 68, three-level separating brake sincere sub 73 and level Four separating brake sincere sub 72 rotate clockwise, and separating brake roller 60 and transmission crank arm 59 are no longer locked
Fixed, transmission crank arm 59 and output shaft 23 quickly rotate clockwise, and output shaft 23 is limited using interior connecting lever 22 and piston 7, output shaft
The rotation of output toggle arm 33 drives switch to complete separating brake movement on 23.
