The invention relates to a film layer cutting mechanism and a film layer cutting device. The film layer cutting mechanism comprises a rack, a cutting tool apron and a cutting blade, and a fixing shaft is arranged on the rack; the cutting tool apron is rotationally connected to the fixing shaft around the axis of the fixing shaft. The cutting blade is fixedly connected to the cutting tool apron. According to the film layer cutting mechanism, the fixing shaft is arranged on the rack, the cutting tool apron is rotationally connected to the fixing shaft around the axis of the fixing shaft, in this way, the cutting tool apron and the cutting blade can both rotate around the axis of the fixing shaft relative to the rack, and during cutting operation, the cutting blade can rotate around the axis of the fixing shaft before the cutting blade makes contact with a to-be-cut film layer; the cutting blade is rotated towards one side close to the to-be-cut film layer, after the cutting blade is in contact with the to-be-cut film layer, the to-be-cut film layer is not only subjected to impact force provided by the cutting blade in the cutting direction, but also subjected to downward pressure provided by the cutting blade, at the moment, a protective film on the to-be-cut film layer cannot be warped and stripped, and the cutting efficiency of the to-be-cut film layer is improved. And the defects of bubbles and the like on the to-be-cut film layer are avoided.
Description
technical field [0001] The present application relates to the technical field of mechanical processing equipment, and in particular, to a film cutting mechanism and a film cutting device. Background technique [0002] The polarizer is an indispensable component in the liquid crystal display to realize imaging. During the processing and production of the polarizer, the polarizer film layer needs to be cut to obtain the required polarizer. In the related art, a cutting device is generally used to cut the polarizer film layer. However, in this process, since the cutter in the cutting device directly impacts the polarizer film layer when entering the knife, the polarizer film will be caused. The protective film on the layer is warped and peeled off, and defects such as bubbles appear on the polarizer film layer, which affect the quality of the product. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a film cutting mechanism and a film cutting devic...
