Abstract

The utility model relates to the technical field of slitting devices for aviation polyurethane protective films, in particular to a slitting device for an aviation polyurethane protective film, which comprises a device body. And the design of the slitting assembly is very ingenious. The first motor drives the rotating shaft, so that the gear drives the third pressing roller to rotate oppositely, the protective film is stably pressed and guided, and it is guaranteed that the film body is flat during slitting. The electric push rod accurately controls the installation sliding frame, and then the slitting knife is driven to conduct accurate slitting. Different from a traditional device for fixing the position of a slitting knife, the device can flexibly adjust the slitting position according to requirements, and the requirement for diversified slitting specifications in the aviation field is met. Under the cooperation of a material pressing assembly, a double-head motor drives a transmission rod through a transmission wheel and a transmission belt, so that an arc-shaped abutting plate on a sliding rod adapts to the thickness change and material difference of the protective film to apply appropriate pressure, it is guaranteed that the slitting edge is neat, the slitting precision is greatly improved, and the strict requirement for the high precision of the polyurethane protective film in the aviation field is met; the product quality is effectively guaranteed.
