[0025] Working principle:

[0026] Plastic film winding work:

[0027] When it is needed to roll up the plastic film, first rotate the bolt 207 outward to make it disengage from the rotating shaft 206, then connect the external power supply of the second motor 201, the second motor 201 starts to drive the worm 202 to rotate in the base 3 through the bearing, the worm 202 drives the worm gear 203 to rotate in the base 3 through the bearing, the worm gear 203 drives the cylinder 204 to rotate in the base 3 through the bearing, the cylinder 204 drives the rotating shaft 206 to rotate synchronously, when the rotating shaft 206 moves 90 degrees to the right, the first motor 201 stops moving, the first motor 201 adopts a servo motor which can rotate a fixed angle;

[0028] At the same time, the worm gear 203 meshes with the worm 202 with self-locking performance, thereby positioning the cylinder 204 and the rotating shaft 206, then insert the sleeve outside the plastic film into the rotating shaft 206, then control the first motor 201 to reverse to reset the rotating shaft 206, then pull the rotating roller 104 upward to make it away from the sleeve, further rotate the bolt 207 inward to make it connect with the rotating shaft 206, so as to limit the rotating shaft 206, then pass the plastic film through the upper end of the straight plate 5 and wind it on the sleeve;

[0029] Pulling the rotating roller 104 upward will drive the inclined rod 103 to move upward, and the inclined rod 103 drives the cross rod 101 to move in the frame 4 through the bearing, at the same time, it will make the torsion spring 102 compressed, after releasing the rotating roller 104, the torsion spring 102 rebounds to push the cross rod 101, the inclined rod 103 and the rotating roller 104 to move reversely, the rotating roller 104 extrudes the plastic film wound on the sleeve, then connect the external power supply of the second motor 205, the second motor 205 starts to drive the rotating shaft 206 to rotate, at the same time, the rotating shaft 206 drives the bolt 207 to rotate outside the multiple rollers 9, the rotating shaft 206 and the bolt 207 rotate in the same direction, so as to drive the sleeve to rotate through the rotating shaft 206 to roll up the plastic film, at the same time, the rotating roller 104 will rotate in the inclined rod 103 through the bearing by friction with the plastic film;

[0030] As the thickness of the plastic film increases, the rotating roller 104 will gradually move upward to keep in contact with the plastic film, when the plastic film is rolled up to a sufficient thickness and needs to be replaced with a new sleeve, turn off the second motor 205, connect the power lines of the two electric telescopic rods 6 to the control board, and connect the external power supply of the two electric telescopic rods 6, the two electric telescopic rods 6 start to drive the cutter 7 to cut the plastic film, the upper end of the straight plate 5 is processed with a knife seat, the cutter 7 is inserted into the knife groove, the lower end of the right side of the knife groove is processed with an opening, the cutting debris falls out and can be easily cleaned, after cutting the plastic film, control the electric telescopic rod 6 to drive the cutter 7 to reset, then rotate the rotating shaft 206 to the right side again to pull out the sleeve and replace it, reset the rotating shaft 206 and limit it by the bolt 207, then the subsequent plastic film can be rolled up in the same way as described above.
