For driving the crank mechanism of cone breaker device
Technical field
A kind of crank mechanism is the utility model is related to, specifically a kind of transmission of crankshaft machine for being used to drive cone breaker device
Structure.
Background technology
Shredder is the equipment generally used in a kind of enterprise and institution and production and living.Generally shredder is all mostly
The shredded paper by the way of motor-driven blade, but due to crushing the normal of the reasons such as paper sheet thickness is larger often blocker blade
Rotate, it is intermittent out of service so as to be in the presence of, it have impact on operating efficiency.
The content of the invention
In view of the above-mentioned problems of the prior art, the purpose of this utility model is to provide and a kind of is able to maintain that blade just
Often rotate, avoid the occurrence of the crank mechanism for being used to drive cone breaker device of paperboard or situation out of service.
To achieve the above object, the technical solution adopted in the utility model is:A kind of bent axle for being used to drive cone breaker device
Transmission mechanism, including paper-breaking device body, the paper-breaking device bodies top are provided with a pair of rotation hobboing cutter axles, the paper-breaking device body one
Side is provided with pedal, and the pedal rear end is hinged on pedal base, and pedal front end is flexibly connected with one end of a connecting rod, connecting rod
The other end is hinged on a bent axle, and big belt wheel and flywheel are installed in described bent axle one end successively;One of rotation hobboing cutter axle
Outer end is provided with small pulley, and the big belt wheel and small pulley are linked together by belt;The pedal front lower surface and pedal
Elastomeric element is provided between base.
Preferably, the bent axle is arranged on pedal base by support frame.
Preferably, described two rotation hobboing cutter axles are combined together by gear engagement.
Preferably, the elastomeric element is three springs being arranged side by side.
The compressed rear caused screen resilience of power and elastomeric element that the utility model user is applied on pedal can cooperate with
Crank rotation is driven by connecting rod;Because big belt wheel and flywheel are arranged on bent axle one end simultaneously, the inertia of flywheel is passed by belt
It is dynamic to drive small band crop rotation to continue ceaselessly to rotate, gear is then transferred force to, the rotation of gear drives rotation hobboing cutter axle to rotate,
Reach the effect of shredded paper.Even if because paper sheet thickness is larger etc., reason applies very big resistance to rotation hobboing cutter axle during shredded paper
Power, because flywheel is heavier, has very big inertia, small pulley can be driven to rotate, overcome resistance, maintain the normal of rotation hobboing cutter axle
Rotation is not in paperboard or situation out of service.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated, a kind of crank mechanism for being used to drive cone breaker device, including paper-breaking device body 10, the shredded paper
The top of device body 10 is provided with a pair of rotation hobboing cutter axles 11, and the lower section of rotation hobboing cutter axle 11 is provided with shredded paper receiver 13, the paper-breaking device
The side of body 10 is provided with pedal 20, and the rear end of pedal 20 is hinged on pedal base 21, the front end of pedal 20 and a connecting rod 22
One end is flexibly connected, and the other end of connecting rod 22 is hinged on a bent axle 23, and the He of big belt wheel 24 is installed in described one end of bent axle 23 successively
Flywheel 25;One of outer end of rotation hobboing cutter axle 11 is provided with small pulley 26, and the big belt wheel 24 and small pulley 26 pass through skin
Band 27 links together;Elastomeric element 28 is provided between the front lower surface of pedal 20 and pedal base 21.
Preferably, in order that the fixed form of bent axle 23 is more firm, the bent axle 23 is arranged on pedal by support frame 29
On base 20.
Preferably, described two rotation hobboing cutter axles 11 are combined together by the engagement of gear 12.
Preferably, in order to ensure to have enough resilience driving forces, the elastomeric element 28 is three springs being arranged side by side.
During work, user steps on pedal 20, and the drivening rod 22 of pedal 20 moves, and connecting rod 22 drives big band by bent axle 23
Wheel 24 rotates, and big belt wheel 24 drives small pulley 26 to rotate by belt 27.When bent axle 23 turns to minimum point, pedal is unclamped
20, screen resilience caused by after elastomeric element 28 is compressed may proceed to rotate with dynamic crankshaft 23 by connecting rod 22;Due to big belt wheel 24
The one end of bent axle 23 is arranged on simultaneously with flywheel 25, and flywheel 25 can rotate simultaneously with big belt wheel 24, and the inertia of flywheel 25 passes through belt
Transmission drives small pulley 26 to make to continue ceaselessly to rotate, and then transfers force to gear 12, and the rotation of gear 12 drives rotation rolling
Cutter shaft 11 rotates, and reaches the effect of shredded paper.Even if because the reason such as paper sheet thickness is larger is to rotation hobboing cutter axle 11 during shredded paper
Apply very big resistance, because flywheel 25 is heavier, has very big inertia, small pulley 26 can be driven to rotate, overcome resistance, maintain
The normal rotation of hobboing cutter axle 11 is rotated, is not in the situation of paperboard.
