Strong machine that rams and become width of cloth pulley gear thereof

The utility model discloses a strong change width of cloth pulley gear that rams the machine includes drive trolley, fixed pulley assembly and the movable pulley assembly of being connected through flexible rope and fixed pulley assembly, and wherein, the rotation axis average level of the movable pulley of the rotation axis of the fixed pulley of fixed pulley assembly, drive trolley's rotation axis and movable pulley assembly is arranged. Because the rotation axis average level of the movable pulley of the rotation axis of the fixed pulley of fixed pulley assembly, drive trolley's rotation axis and movable pulley assembly arranges that when the ram released, the cantilever crane rebounded, with drive trolley, fixed pulley and movable pulley butt during flexible rope up -and -down motion, avoid flexible and restrict by the circumstances of drive trolley, fixed pulley and movable pulley landing, consequently, the change width of cloth pulley gear that this application provided has improved the strong work efficiency who rams the machine. The utility model also discloses a strong machine that rams that is including the above -mentioned width of cloth pulley gear that becomes.
