The invention discloses a fabric shredding device specially for fabric with high structural strength. The fabric shredding device comprises a puncturing structure, a first shredding structure and a second shredding structure, wherein the puncturing structure comprises a puncturing box; a first fabric charging opening is formed at the top of the puncturing box; a first discharging opening is formedat the bottom of the puncturing box; four pneumatic cylinders are arranged on the outer wall of the puncturing box; each of the pneumatic cylinders is connected to the outer wall of the puncturing box through a corresponding pneumatic cylinder installation base; a corresponding piston rod on each of the pneumatic cylinders movably penetrates through the puncturing box and is connected to the front end of a pushing plate in the puncturing box; and a plurality of puncturing rods are arranged at the rear end of the pushing plate. The fabric shredding device specially for the fabric with high structural strength can more easily shred the waste fabric while effectively solving the problem of jamming of the shredding structures; the fabric shredding device not only avoids the situation that thestop of the device affects the shredding efficiency, but also prolongs the service lives of the shredding structures; in addition, the fabric shredding device improves the shredding quality without the need for screening and another time of shredding, and reduces the workload of the operators; and the fabric shredding device has the advantages of being simple in operation, long in service life, low in maintenance cost, not prone to damage and the like.
