[0034] In summary, in the utility model, a polyethylene coated paper roll to be trimmed is sleeved on the first roller 102, and the polyethylene coated paper roll to be trimmed is fixed on the second roller 105 through the auxiliary rotating wheel 104, and the power motor 103 is started and drives the second roller 105 to rotate, and then the polyethylene coated paper to be trimmed is pressed down by the auxiliary rotation of the auxiliary rotating wheel 104 to straighten the polyethylene coated paper to be trimmed to prevent wrinkles on the polyethylene coated paper to be trimmed, and the rotation of the polyethylene coated paper roll to be trimmed drives the first roller 102 to rotate, and then the cutting knife 203 is used to trim the edges, and the sensor is used to control the extension of the telescopic rod 211 according to the thickness of the polyethylene coated paper roll to be trimmed to achieve the lowering of the cutting knife 203. The telescopic rod 211 is a common electric telescopic rod.

When the thickness of the polyethylene coated paper roll to be trimmed is reduced to the point where the cutting knife 203 is about to contact the first roller 102 When touching, the polyethylene coated paper to be trimmed first contacts the contact rod 209, and the contact rod 209 slides downward in the internal slide groove of the outer frame 101 through the sliding rod 210, wherein the contact rod 209 has a certain thickness, which can prevent the polyethylene coated paper to be trimmed from contacting the sliding rod 210, thereby driving the lifting belt 208 to move, and then the lifting shaft 207 assists in rotation, and then drives the lifting block 206 to rise and slide in the lifting slide 205 through the lifting belt 208, so that the top of the lifting block 208 contacts the lifting rod 204 and the lifting rod 204 rises, thereby driving the cutting knife 203 to rise, and then the sensor senses the additional upward pressure and converts the pressure signal into an electrical signal to control the telescopic rod 211 to retract. If the second roller 105 completes winding, the cutting is stopped and a new polyethylene coated paper roll to be trimmed is replaced, then the sensor controls the telescopic rod 211 to reset, and the lifting block 206 slides downward using gravity, thereby driving the contact rod 209 to reset.

[0035] The upper and lower parts of the utility model are provided with a plurality of rollers 314, 316 and 317, respectively, which are used for the rollers 314 to move upwards and downwards, so as to prevent the rollers 314 from sliding upwards and downwards, thereby preventing ... When the first roller 102 rotates, it drives the friction pulley 106 to rotate, and then drives the winding track 302 to rotate, and then drives the winding pulley 301 to rotate, and then drives the winding gear 303 to rotate, and then drives the winding gear 303 to drive the winding disk 309 to rotate, and then drives the winding rod 314 to clamp the waste and rotate and reel it. When the reeling is completed, the winding track 302 stops rotating, and the infrared sensing device controls the controllable contraction spring rod 306 to make the translation gear 304 return to the inside of the reel 309 and disengage from the reel gear 303, and the reel rod 314 stops rotating, and then controls the controllable contraction spring rod 306 to reset the top block 313, so that the reel rod 314 is loosened a certain distance.

[0036] In the utility model, after the winding unit 3 completes the winding, the recovery unit 4 is used to start the translation motor 403, thereby driving the translation motor 403 to move to a suitable position, and the displacement of the movement can be set in advance in the program, and at the same time, the clamping motor 406 is started to drive the clamping stud 407 to rotate, thereby driving the clamping bottom plate 408 to rise upward under the action of the thread and cooperate with the clamping top plate 405 to clamp the winding waste, and then the translation motor 403 is used to move the waste to the top of the recycling box 401, and the translation motor 403 slides on the recycling rod 402, and controls the clamping motor 406 to make the clamping bottom plate 408 move down to loosen the waste, thereby making the waste fall into the recycling box 401 to complete the recycling work.
