Sheath press-fitting device for plastic film

The invention relates to the technical field of plastic film production, in particular to a plastic film sheath press fitting device which comprises a bottom plate, a controller is mounted on one side of the bottom plate, two supports are fixed to the two ends of the upper side of the bottom plate, servo electric cylinders are mounted on the upper sides of the two supports, and the two servo electric cylinders are electrically connected with the controller. According to the invention, through the sheath flaring mechanism, when the sheath is pressed, the port of the sheath can be expanded by a certain diameter, so that the sheath can sleeve the outer side of the end part of the plastic film winding roller more easily, and the situation that the outer side of the plastic film winding roller is wrinkled and damaged due to friction between the sheath and the outer side of the plastic film winding roller caused by too tight port of the sheath is avoided. 本发明涉及塑料薄膜生产技术领域，尤其是涉及一种塑料薄膜的护套压装装置，包括底板，所述底板的一侧安装有控制器，且底板的上侧
