Crimping machine with dust collection function and winding roller convenient to disassemble and assemble

The utility model relates to the technical field of polypropylene staple fiber production, and discloses a crimping machine with a dust collection function and a winding roller convenient to disassemble and assemble, which comprises a device base, a mounting component arranged on the left side of the top of the device base and a driving component arranged on the right side of the top of the device base. By installing the first motor, the placement frame and the dust collection pipe, when dust collection treatment needs to be conducted on fiber materials, the first motor is controlled to drive the turbine blades to rotate, so that dust of the fiber materials on the winding roller is adsorbed into the inner cavity of the box body through the dust collection pipe by the turbine blades; when a fiber material is wound on the winding roller, the placing frame moves downwards due to the increase of the thickness of the fiber material on the winding roller, so that the placing frame drives a connecting rod to downwar
