As shown in Figure 7, in specific embodiment, governor motion comprises claw 365, buckle spring 366, shift fork 371 and shift fork 371 is rotated the handle mechanism of adjusting that it specifically is assembled into: first tie point on the claw 365 and bayonet lock 363 stretch out pressing plate 364 outer ends and be connected; Buckle spring 366 is in elastic deformation (being compressive state in one embodiment), and an end and the pressing plate 364 of buckle spring 366 are connected, and second tie point on the other end and the claw 365 is connected; Shift fork 371 is hinged by declutch shift shaft and frame 1, and shift fork 371 cooperates with the clamping working face B of claw 365, to pass through rotation and claw 365 clampings or disengaging.Wherein, shift fork 371 is rotated adjusting by handle mechanism, and this handle mechanism is specially: shift fork 371 is connected with spring axle 372; Clutch rotating shaft 375 is installed on the frame 1; Be hinged with clutch handle 374 in the clutch rotating shaft 375, clutch handle 374 is provided with notched plate, notched plate is provided with elongated hole, the length direction of elongated hole becomes the angle of preset angles with the axis direction of handle, spring axle 372 is slidingly connected with elongated hole, is provided with back-moving spring between clutch rotating shaft 375 and the clutch handle 374.In specific embodiment, clutch handle 374 1 ends are hinged in the clutch rotating shaft 375, and the other end is provided with handle 377.Further, be fixed with pedal clutch plate 376 in the clutch rotating shaft 375, the length direction of pedal clutch plate 376 is vertical with the axis direction of clutch rotating shaft 375.
Please refer to Fig. 2 and Fig. 3, and Fig. 8 to Figure 10, this machine operation principle is: motor 2 energising rotations, by conveyer belt 21 transmissions, mechanical kinetic energy is delivered on the flying wheel 31, flying wheel is delivered to mechanical kinetic energy with it on joining first tooth 32, axle tooth 32 is delivered to mechanical kinetic energy on the gear 33 that is meshed with it, gear 33 is installed on second tooth 34, second tooth 34 is delivered to mechanical kinetic energy on the clutch gear 362 that is meshed with it, clutch gear 362 with the engaging process of gear core retainer plate 361 in, mechanical kinetic energy is delivered on the bent axle 35 of mounting teeth wheel core housing 361; Installing connecting rods 37 on the cam of bent axle 35, and frame 1 is provided with limiting rod 37 straight-line inner slides, thereby rotation function is changed over straight line slippage kinetic energy, to realize the rectilinear motion of connecting rod 37; One end of connecting rod 37 and the cam of bent axle 35 are hinged, and the other end is equipped with cutting blade 91, and this cutting blade 91 is cambered blade; When connecting rod 37 runs to range, with the ledger-plate 92(that is installed in frame 1 head also for cambered blade) form and cut off clip, with bar cutting, then, connecting rod 37 return back to initial position under the drive of the rotation function of bent axle 35 overhead cams, finish a working cycles.
Please refer to Fig. 4 to Fig. 7, the operation principle of this machine clutch is: the gear core retainer plate, and 361 are installed on the clutch gear 362, and bayonet lock 365 is installed in the groove D of gear core retainer plate 361.Pressing plate 364 is installed on the boss of gear core retainer plate 361, uses bolting, and after fixing, gear core retainer plate 361 can freely rotate in the centre bore of clutch gear 362; Claw 365 is welded on the input (being that bayonet lock 363 stretches out the end outside the pressing plate 364) of bayonet lock 363, and buckle spring 366 1 ends are connected with claw 365, and an other end is fixed by bolts on the pressing plate 364; Shift fork 365 is by rotation and claw 365 clampings or disengaging, particularly, shift fork 365 is connected with declutch shift shaft and is hingedly mounted on the frame 1 by declutch shift shaft, simultaneously, shift fork 365 is connected with spring axle 372 and is slidingly connected by the elongated hole on spring axle 372 and the clutch handle 374, clutch handle 374 is hinged by back-moving spring and clutch rotating shaft 375, and clutch rotating shaft 375 is installed on the frame 1.
Thereby, by the assembling of shift fork 371 with handle mechanism, when manually stirring clutch handle 374, shift fork 371 rotates and lifts along declutch shift shaft, the clamping working face B that breaks away from claw 365, when shift fork 371 lifts, claw 365 drives bayonet lock 363 together along the rotation rotation of bayonet lock 363 under the traction of buckle spring 366 pulling force, the clamping block of bayonet lock 363 lifts, the wedge angle of clamping block cooperates with draw-in groove E on the clutch gear 362, clutch gear 362 driven gear core retainer plates 361 rotate synchronously, and gear core retainer plate 361 centre bores are installed on the bent axle 35, thereby bent axle 35 obtains rotary power, drivening rod 37 is done rectilinear motion, cuts off the reinforcing bar operation.After bent axle 35 arrived the eccentric throw fixed point, clutch gear 362 driven gear core retainer plates 361 continued rotation, and connecting rod 37 is return.
When clutch handle 374 loses external tensile force, traction turning down at back-moving spring, shift fork 371 is fallen along the declutch shift shaft revolution, gear core retainer plate 361 is being with claw 365 still in rotation at this moment, when claw 365 rotates to shift fork 371 positions and the shift fork clamping, claw 365 is returned in the groove D of gear core retainer plate 361 under the stopping of shift fork 371.At this moment, clutch gear 362 disconnects transmission of power with gear core retainer plate 361, and namely clutch gear 362 continues rotation, and gear core retainer plate 361 stops operating.After this, continue with hand pulling handle 377 or the foot-operated clutch plate 376 that tramps with one's feet down, clutch can repeat above-mentioned action, cuts off operation.Above-mentioned transmission flow process is seen accompanying drawing 11.
In order further to optimize technique scheme, as shown in Figure 7, the one side that bayonet lock 363 contacts with groove D bottom land on the gear core retainer plate 361 is first, the one side relative with first is second C, second C is the plane, thereby when clutch gear 362 backward rotation, bayonet lock 363 can not carry out clamping with clutch gear 362 and gear core retainer plate 361, namely can not realize transmission of power.Thereby, before machine startup, if power source (being motor 2) turns to and closes with this machine different design and start, can not cause clutch to damage.
In specific embodiment, motor 2 is the Y100L2 threephase asynchronous, and conveyer belt 21 is the V-belt, but those skilled in the art can also adopt other replacement scheme, so the utility model is not done restriction to this.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
