Shearing device for mask processing

The utility model relates to the technical field of mask processing, and discloses a shearing device for mask processing, which comprises a case, the top surface of the case is fixedly connected witha shearing template, one side of the top surface of the shearing template is provided with a pressing plate, and the bottom surface of the pressing plate is fixedly provided with an electric telescopic rod. The second servo electric cylinder drives a shearing structure formed by the seven sets of first servo electric cylinders and the shearing blade in the connecting frame to penetrate through thepositioning plate to be matched with the positioning plate so as to automatically cut mask cloth clamped on the top face of the shearing template at a time. A traditional sequential cutting mode is replaced; in addition, a positioning anti-deviation structure formed by connecting a positioning plate, a main sleeve rod, a movable rod and an anti-deviation block can synchronously move along with the shearing structure, the
