Detailed Description

As shown in fig. 1 to 4, a scrap cutter shearing mechanism convenient to disassemble and assemble comprises a base 1, a sliding seat 2, a sliding rail 3, an eccentric wheel 6 and a cylinder 9, wherein the sliding rail 3 is arranged on the base 1, the sliding seat 2 is arranged on the sliding rail 3, and the sliding seat 2 is detachably arranged on the sliding rail 3. Realize whole dismouting of whole garrulous limit and cut shearing mechanism.

The sliding seat 2 is provided with an electric motor 10, an output shaft of the electric motor 10 is connected with a rack 12 through a gear box 11, and the rack 12 is provided with an upper cutter disc 13 and a lower cutter disc 14.
