Pressure adjusting mechanism of hob film cutting machine

The utility model relates to the technical field of film cutting machine adjusting mechanisms, and discloses a pressure adjusting mechanism of a hob film cutting machine, which comprises a frame body, and the two sides of the frame body are provided with mounting grooves; the adjusting rod is installed at the top of the frame body and used in cooperation with the first bevel gear and the second bevel gear, the two adjusting bolts can rotate synchronously, and therefore the two bearing seats drive the first rotating rod to adjust the height, independent adjustment is not needed, the situation that bearings on the two sides are uneven in stress is prevented, and the service life of the bearing is prolonged. The service life of a bearing is guaranteed, traditional gear transmission is changed into rotating wheel transmission, and a tensioning wheel is used in a matched mode, so that the device can be debugged in the working period, normal transmission can still be conducted after the distance between the first r
