The first reduction gear and the second reduction gear are fixedly arranged. By adopting this setting, reasonable deceleration can be carried out and excessive speed can be avoided.

Preferably, the ratchet mechanism includes a ratchet and a transmission hook arranged on the four-bar mechanism to drive the ratchet to rotate. By adopting this arrangement, the pulley can be driven to rotate to realize material movement.

Preferably, a rectangular folding opening is provided in the middle of the horizontal axis, a cylindrical ring is set on the rectangular folding opening, and the cutting knife is sleeved on the cylindrical ring through a connecting rod. By adopting this arrangement, it can be realized that the cutting knife always keeps moving in the vertical direction during the rotation of the horizontal axis.

Beneficial effect:

The utility model adopts the above-mentioned technical scheme to provide a plate blanking mechanism based on a ratchet mechanism, which makes up for the deficiencies of the prior art, and has reasonable design, simple structure, convenient operation, safe use, easy disassembly and good working effect.
