Description
Technical field
The present invention relates to cutting equipment, more particularly to a kind of shut-off mechanism that drives of motor positive and inverse alternate run and its cut
Disconnected method.
Background technology
In the motor-driven shut-off mechanism of prior art, all it is often by turning to the motor for rotating drive to determine
Rotation is switched to translation to drive cutting knife to move up and down by connecting rod, completes cut-out action by driving wheel.Fig. 1-3 shows one
The shut-off mechanism of prior art and its working cycles.
As shown in figure 1, the shut-off mechanism of prior art includes upper cutter 1, lower cutter 2, connecting rod 3 and driving wheel 4.Wherein,
Lower cutter 2 is fixed, and upper cutter 1 is arranged to move up and down；The edge of a knife of the edge of a knife of upper cutter 1 and lower cutter 2 that
This is relative, and as upper cutter 1 is moved from top to bottom, the distance between two edges of a knife are reduced to 0 from h；With upper cutter 1 from the bottom up
Mobile, the distance between two edges of a knife increase to h from 0.Driving wheel 4 is connected to motor by the rotating shaft in through its center hole, thus
Motor drives axis of rotation and thus drives driving wheel 4 to rotate.It is connected by connecting rod 3 between upper cutter 1 and driving wheel 4, connecting rod 3
One end be connected with upper cutter 1 and can around between the two junction occur relative to upper cutter 1 rotation, the other end of connecting rod 3
The rotation for being connected with driving wheel 4 and can occurring relative to upper cutter 1 around junction between the two, the connection of connecting rod 3 and driving wheel 4
Place is arranged on distance and passes through at the position of axle h/2 of driving wheel 4.
The driving wheel 4 of the shut-off mechanism of the prior art shown in Fig. 1-3 is arranged to rotate counterclockwise (such as the arrow in figure
