Film tearing device and clean bag manufacturing system

The invention discloses a film tearing device and a clean bag manufacturing system, relates to the technical field of biological pharmacy, can replace manual film tearing, and can ensure the consistency of each time of film tearing, that is, the sizes of triangles formed after film tearing are consistent. The film tearing device comprises a bearing mechanism, a controller, a driving mechanism and two clamping mechanisms, wherein the driving mechanism and the two clamping mechanisms are connected with the controller. The bearing mechanism is provided with a bearing platform, the two clamping mechanisms are arranged at the first end of the bearing platform side by side and used for clamping a membrane material, and the first end of each clamping mechanism is rotationally connected with the bearing platform. The driving mechanism is connected with the bearing platform and located below the two clamping mechanisms. The driving mechanism is connected with the second end of each clamping mechanism and used for driv
