Carrier roller adjusting device for plastic film processing

The invention provides a carrier roller adjusting device for plastic film processing. The device comprises a bottom plate, a mounting frame and a carrier roller shaft. The carrier roller shaft is movably mounted on the inner side of the mounting frame, a rectangular frame is welded to the inner side of the mounting frame, an angle measuring mechanism is arranged on the inner side of the rectangular frame, and limiting frames are welded to the two sides of the bottom of the mounting frame. The angle of a carrier roller can be accurately adjusted, the operation of shutdown adjustment can be avoided, and the problems that the precision of the tilting angle of an existing hydraulic drive is difficult to guarantee, meanwhile, maintenance and adjustment of double hydraulic cylinders are not beneficial to long-term use of the equipment, a large amount of time is spent on the point inspection and maintenance of hydraulic sealing pieces and pistons, production of films in a large scale is not facilitated, the inclinat
