According to an embodiment of the present invention, as shown in fig. 1, it can be seen that the roll-to-roll film feeding and peeling assembly 31 includes:
a mounting base 311;
a coil mounting frame 312 slidably connected to the mounting base 311;
a coil discharging tray 313 rotatably connected to the coil mounting frame 312, the coil discharging tray 313 being wound with a film coil;
a release paper receiving roller 315 rotatably connected to the web mounting frame 312; and
a film stripping module 318, provided with a wedge-shaped film tensioning die 3181,
the film coil discharged from the coil discharge tray 313 bypasses the wedge-shaped tip of the film tensioning die head 3181 and is wound by the release paper collecting roller 315, and the film coil is made of a flexible material, so that the film on the film coil is easily peeled off after the film coil is bent by the wedge-shaped tip of the film tensioning die head 3181.
Further, the roll mounting frame 312 is provided with a roll guide rail extending along a horizontal plane, and the film roll discharged from the roll discharge tray 313 is laid flat on the roll guide rail. Thereby preventing the film rolls discharged from the roll discharge tray 313 from being entangled with each other.
Referring next to fig. 2, which shows the specific structure of the film stripping assembly 318 in detail, the film stripping module 318 is further provided with a film stripping actuator 3182, and the film tensioning die 3181 is in driving connection with the film stripping actuator 3182.
