An electric push rod precisely controls the mounting carriage, which in turn drives the slitting blade for accurate slitting. Unlike traditional devices with a fixed slitting blade position, this device can flexibly adjust the slitting position according to requirements, meeting the diverse slitting specifications in the aviation field. With the cooperation of the pressure assembly, a dual-head motor drives a transmission rod through a transmission wheel and belt, causing the arc-shaped abutment on the slide rod to apply appropriate pressure according to changes in the thickness and material differences of the protective film, ensuring neat slitting edges, greatly improving slitting accuracy, meeting the stringent high-precision requirements of the aviation field for polyurethane protective films, and effectively guaranteeing product quality.

The transverse frame 2312 is fixedly connected to the top of the device body 1, and the second motor 2313 is fixedly installed on the outer end of the transverse frame 2312. The drive shaft 2314, which is fixedly connected to the output end of the second motor 2313, rotates under the drive of the second motor 2313. The drive roller 2315, which is fixedly connected to the outer wall of the drive shaft 2314, drives the transmission. The conveyor belt 2316 operates; the conveyor belt 2316 can transport the slit protective film to the designated position; the fixed mounting bracket 2317 is fixedly connected to the inside of the mounting bracket 237, and the bottom of the bracket is fixedly connected to the connecting spring 2318 and the pressure block 2319. During the slitting process, the rollers 2320 rotatably connected to the inside of the pressure block 2319 are symmetrically arranged on the top of the conveyor belt 2316, which can feed the slit protective film to ensure that the slit protective film can be smoothly transported, and at the same time play a certain role in pressing and guiding, preventing the protective film from shifting or wrinkling during the transport process.
