Since the first eccentric rod 64 and the second eccentric rod 66 do not rotate in the same horizontal direction, the counterweight 3 and the fixed blade carrier 22 are finally slid in opposite directions to each other.

In summary, the following steps:

the counterweight 3 and the fixed tool rest 22 slide in opposite directions to reduce the inertia of the movable tool rest 2 during reciprocating sliding, thereby improving the running stability of the honeycomb paper core shearing device.
