[0029] Two fixing plates 3 are provided, and the two fixing plates 3 are symmetrically arranged around the center of the support column 1 . The top of the base 8 is semicircular, and the diameter of the semicircle is the same as the outer diameter of the cutting motor 9 .

[0030] The sides of the two fixed plates 3 close to each other are rotatably connected to the first guide roller 11 , the sides of the two fixed plates 3 close to each other are rotatably connected to the second guide roller 12 , and the top of the operating table 2 is fixedly connected to a mounting frame 13 .

[0031] Two first guide rollers 11 are provided, and the two first guide rollers 11 are symmetrically arranged around the center of the fixed plate 3 . The height of the bottom of the first guide roller 11 is lower than the height of the top of the cutting knife 10 , and the height of the second guide roller 12 is greater than the height of the first guide roller 11 .

[0032] A second motor 14 is fixedly connected to the side wall of the mounting frame 13, and an output end of the second motor 14 is rotatably connected to the inside of the mounting frame 13. The output end of the second motor 14 passes through and extends from the side wall of the mounting frame 13. A placement rod 15 is fixedly connected to the output end of the second motor 14, and a front baffle 16 is fixedly connected to the outer wall of the placement rod 15.

[0033] A threaded groove 17 is provided on the placement rod 15, a rear baffle 18 is sleeved on the outer wall of the placement rod 15, a threaded barrel 19 is threadedly connected to the threaded groove 17, the threaded barrel 19 is rotatably connected to the side wall of the rear baffle 18, and a handle 20 is fixedly connected to the side wall of the threaded barrel 19.

[0035] The implementation principle of an electronic film slitting device in the embodiment of the present application is as follows: when in use, the roller rolled with the electronic film is sleeved on the left placement rod 15, and then the rear baffle 18 is sleeved on the left placement rod 15, the threaded cylinder 19 is aligned with the threaded groove 17, and then the threaded cylinder 19 is rotated clockwise. The rotation of the threaded cylinder 19 will cause the threaded cylinder 19 to move along the placement rod 15 toward the front baffle 16, and the threaded cylinder 19 pushes the rear baffle 18 to move, thereby fixing the roller rolled with the electronic film between the front baffle 16 and the rear baffle 18, which can prevent the roller from moving and causing the cutting position to deviate. Then, the same method is used to fix two winding rollers of different sizes on the right placement rod 15, and then the first motor 4 is started. The operation of the first motor 4 drives the threaded rod 5 to rotate, and the sliding rod 6 is limited by the threaded rod 5 and the sliding rod 6 , and cannot rotate, so that when the threaded rod 5 rotates, the sliding rod 6 will move along the threaded rod 5, the threaded rod 5 drives the base 8 to move, the base 8 drives the cutting motor 9 to move, and the cutting motor 9 moves to drive the cutting knife 10 to move, and the position of the cutting knife 10 is changed, so that two electronic films of different sizes can be cut out, and the adjustment is more convenient. The electronic film passes through the bottom of the two first guide rollers 11 and passes through the top of the second guide roller 12. On the two winding rollers fixed on the right placement rod 15, start the second motor 14 and the cutting motor 9 to complete the winding and cutting. Because the height of the first guide roller 11 is lower than the second guide roller 12, and the height of the placement rod 15 is lower than the second guide roller 12, tension will be generated on the electronic film during the winding process to make the electronic film taut, thereby ensuring the flatness of the electronic film during winding.

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.
