[0034] The implementation principle of a PET film slitting device in the embodiment of the present application is as follows: four turntables 305 are rotated synchronously together, so that the threaded rod 304 drives the slider 303 at the bottom to perform lifting movement in the slide groove 1 302, so that the slider 303 drives the rotating shaft 307 to lift and lower, and the guide wheel 2 106 is taken out from the U-shaped groove of the support rod 2 105, and the fixing plate 107 is also taken out from the guide wheel 2 106, and the PET paper tube is inserted into the outer wall of the guide wheel 2 106, and the guide wheel 2 106 and the fixing plate 107 are put back, and the fixing plate 107 is adjusted to make it fit with the PET paper tube, so as to prevent the PET paper tube from rotating. During the process, the steel strip 115 deviates to the left and right, and the pull rod 110 is loosened to use the tension of the spring to push the elastic steel strip 115 to slide forward on the inner wall of the guide wheel 106. The limit of 117 on 111 can prevent 110 from rotating, thereby ensuring that the clamping head on 115 and 109 are located in the same vertical plane. When the clamping head at the front end of the elastic steel strip 115 and the clamping hole 109 are located in the same vertical line, the tension generated by the small spring 116 pushes the elastic steel strips 115 on both sides to fully open, so that the clamping head passes through the clamping hole 109 and presses against the inner wall of the PET paper tube, thereby preventing the PET paper tube from shaking during the rotation. Pull one end of the PET paper tube to make the PET film and the three guide rollers 104 wrap up and down, so as to pull up and tighten the cloth, so that it passes through the two guide wheels 308 and the blade 206, and at the same time rotate the turntable 305 to make the two guide wheels 308 fit closely with the table 101, then start the motor 306 to drive the shaft 3 307 and the guide wheel 308 to rotate, and the belt 310 connected to the pulley 309 at one end of the shaft 3 307 drives another pulley 309 to rotate, thereby driving another guide wheel 308 to rotate, so that the PET film moves to the end on the table. This is to start the motor 1 202 to drive the shaft 2 203, and the shaft 2 203 drives the blade 206 with the distance adjusted, so as to cut the PET film into multiple sizes.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
