[0037] The above is a description of the various structural components, connection relationships and functions of this embodiment. The following will describe the usage status of the film cutting machine in combination with this embodiment.

[0038] When the user needs to cut the protective film, he inputs the pre-planned size data on the control screen 2, and then extends the protective film into the pressure roller 3 along the guide block 6. During this process, the detection device detects that the protective film passes from above, and sends a signal to start the second motor 42. The second motor 42 drives the second belt 44 to drive the pressure roller 3 to rotate, pressing the protective film into the pressure roller 3. When the sensing device senses that the protective film has passed from above, it sends another signal to stop the second motor 42 and the pressure roller 3. Then the first motor 41 starts, and the first motor 41 drives the first belt 43 to rotate, driving the slider 53 to slide along the length direction of the first guide rail 51 and the second guide rail 52, so that the knife sleeve 54 drives the film cutting knife 55 to complete the protective film cutting step. Finally, through the cooperation of the second motor 42, the second belt 44, the pressure roller 3 and the detection device, the protective film is withdrawn from the film cutting machine, and the film cutting machine returns to its initial state and waits for the next protective film cutting instruction.

[0039] The beneficial effects of the present invention are as follows: the film cutting machine is configured to consist of five parts: a casing, a control panel, a pressure roller, a drive assembly and a tool assembly, wherein the drive assembly and the tool assembly are fixedly arranged inside the casing along the width direction of the film cutting machine, the control panel is used to control the drive assembly to drive the tool assembly to cut the protective film, the tool assembly includes upper and lower guide rails arranged inside the casing, and the drive assembly includes upper and lower motors and belts arranged, which fully utilize the vertical space, reduce the floor space occupied by flat placement, and make the spatial layout of the various components of the film cutting machine more reasonable.
