Existing flat die-cutting machine in the course of the work, such as the rocking arm 7 in (Fig. 1) power-transmitting unit when centered by fulcrum 11, doing up and down circular motion, under the identical power effect of lever principle; the power that produces the closer to the place of fulcrum 11 on the rocking arm 7 is larger, and the pressure of bent axle 10 is also larger.Because excessive motion inertia force; rocking arm 7 is easy to occur shock problem when moving downward; thus falling of paper roll caused; simultaneously; under the impact of impact force; the component of whole die-cutting machine can produce very large dynamic stress, and may cause the destruction of bent axle 10, thereby shorten the working life of die-cutting machine.
The model utility content
For the deficiency that exists in the above-mentioned technology, the utility model provides a kind of damping device of power-transmitting unit, effectively alleviates inertial force and the pressure of bent axle, the high working efficiency that has improved flat die-cutting machine and working life that rocking arm moves downward.
For achieving the above object, the utility model provides a kind of damping device of power-transmitting unit, comprises elastic component, adjusting nut, the first elastic component seat, the second elastic component seat, the first axle, the second axle, rocking arm and support; One end of described elastic component is connected with the first axle by the first elastic component seat, the other end of described elastic component is connected with the second axle by the second elastic component seat, described the first axle is installed in the rocking arm, and described the second axle is fixed on the support, and described elastic component is connected with adjusting nut.
Wherein, the damping device of described power-transmitting unit also comprises interstage sleeve; Described the first axle is installed in the rocking arm by interstage sleeve.
Wherein, the damping device of described power-transmitting unit also comprises travel axis; Described the first elastic component seat connects the second elastic component seat by travel axis.
The beneficial effects of the utility model are: compared with prior art, the damping device of the power-transmitting unit that the utility model provides, the first axle are mounted in the rocking arm, and flat die-cutting machine is when work, the first axle is along with rocking arm moves up and down, and the second axle is to be fixed on to keep transfixion on the support; The motion of the first axle impels the first elastic component seat that elastic component is done periodic compression, produce a power that makes progress, rocking arm is played one to be lifted, simultaneously, can be by the reduction length of adjusting nut adjustable elastic spare, can offset the downward inertial force of a rocking arm part, alleviate the pressure of bent axle, play cushioning effect.The utlity model has that the downward motion inertia force of rocking arm is little, bent axle pressure is little, the advantage such as high working efficiency and long service life.
Description of drawings
Fig. 1 is the structural drawing of the damping device of power-transmitting unit of the present utility model;
Fig. 2 is the partial schematic diagram of the damping device of power-transmitting unit of the present utility model.
The primary component symbol description is as follows:
1, elastic component 2, adjusting nut
3, the first elastic component seat 4, the second elastic component seat
5, the first axle 6, the second axle
7, rocking arm 8, support

Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing the utility model is done to describe further.
See also Fig. 1-2, the damping device of the power-transmitting unit that the utility model provides comprises elastic component 1, adjusting nut 2, the first elastic component seat 3, the second elastic component seat 4, the first axle 5, the second axle 6, rocking arm 7 and support 8; One end of elastic component 1 is connected with the first axle 5 by the first elastic component seat 3, and the other end of elastic component 1 is connected with the second axle 6 by the second elastic component seat 4, and the first axle 5 is installed in the rocking arm 7, and the second axle 6 is fixed on the support 8, and elastic component 1 is connected with adjusting nut 2.
Compared to the situation of prior art, the damping device of the power-transmitting unit that the utility model provides, the first axle 5 are mounted in the rocking arm 7, therefore, flat die-cutting machine is when work, and the first axle 5 is along with rocking arm 7 moves up and down, and the second axle 6 is to be fixed on the support 8, keeps transfixion; The motion of the first axle 5 impels 3 pairs of elastic components 1 of the first elastic component seat to do periodic compression, produce a power that makes progress, rocking arm 7 is played one to be lifted, simultaneously, can be by the reduction length of adjusting nut 2 adjustable elastic spares 1, can offset the downward inertial force of rocking arm 7 parts, alleviate the pressure of bent axle 10, play cushioning effect.The utlity model has that the downward motion inertia force of rocking arm 7 is little, bent axle 10 pressure are little, the advantage such as high working efficiency and long service life.
In the present embodiment, the damping device of power-transmitting unit also comprises the interstage sleeve (not shown); The first axle 5 is installed in the rocking arm 7 by the interstage sleeve (not shown); In the process of installing, the interstage sleeve (not shown) plays the effect of protection the first axle 5, so that the first axle 5 is along with the action that rocking arm 7 moves up and down is more smooth and easy.Certainly, the utility model is not limited to the first axle 5 and is installed in mode of execution in the rocking arm 7 by the interstage sleeve (not shown); The first axle 5 can also be installed in other mode of executions in the rocking arm 7 by gear film or plug etc.; so long as the first axle 5 is installed in the change of the mode of rocking arm 7 interior employings; all belong to simple variation of the present utility model or conversion, fall into protection domain of the present utility model.
