[0002] At present, many electronic devices with glass panels have a protective film on the surface to prevent scratches. Since the glass panels of many devices are of different sizes, users often need to customize them individually. Therefore, a DYI film cutting device has been launched on the market. It integrates the Internet of Things through an automated structure. Customers can choose the required product model according to the needs of the device, and the automatic tool inside it completes the cutting of the protective film, realizing self-service customization.

[0003] The above film cutting machine controls the cutting action of the tool on the X-axis through an electric slide rail, drives the protective film blank to move along the Y-axis through a pressure wheel assembly on one side, and cooperates with the cutting tool moving on the X-axis to achieve contour cutting. However, at present, the pressure wheel assembly of such film cutting machines mostly clamps the film blank through an elastic pad on the surface, and its rebound space is limited, and it cannot adapt to films with a larger thickness range. Moreover, since its clamping force cannot be flexibly adjusted, the clamping force is low when holding thinner blanks, and idling is prone to occur, resulting in cutting errors. When the blank is thick, the pressure is too high, which easily causes the protective film to bend and deform under pressure. Utility Model Content
