[0032] Working principle of this utility model:

[0033] When in use, the waste cotton is spread on the conveyor belt 101, and the conveyor belt 101 is used to transport it to the loosening bin 200. During the process, the spread cotton will be squeezed by the squeezing roller 201 and the squeezing belt 202 to prevent too much cotton from being pulled out at one time. During the process, the motor 405 can be turned on, and the output end of the motor 405 will drive the first linkage pulley 406 to rotate. The rotating first linkage pulley 406 will drive the first driven pulley 408 to rotate through the cooperation with the first belt 407. The rotating first driven pulley 408 will drive the support shaft 203 to rotate in the two rotating holes 219 to prevent the support shaft 203 from deviating. The support shaft 203 will rotate in the two limiting holes 216 while rotating. The continuously rotating support shaft 203 will drive The opening roller 204 rotates, so that the opening roller 204 drives the multiple fixed strips 206 to rotate around the opening roller 204 through the cooperation with the multiple positioning grooves 205, and the rotating fixed strips 206 will drive the movable strips 208 to rotate synchronously, thereby driving the fixed pine needles 207 and the movable pine needles 209 on the movable strips 208 to rotate. During the rotation of the fixed pine needles 207 and the movable pine needles 209 around the opening roller 204, they will be inserted into the cotton transported to the opening bin 200, and part of the cotton will be pulled out, thereby achieving the effect of opening the cotton, and the movable strips 208 will drive the connecting frames 210 at both ends to rotate during the rotation, and the connecting frames 210 will drive the rollers 211 to rotate. Since the arc-shaped extrusion blocks 213 on both sides are staggered, the two rollers 211 are in a staggered arrangement. When rotating around the opening roller 204, one of the rollers 211 will contact the arc-shaped extrusion block 213, and at the same time will be squeezed by the arc-shaped extrusion block 213 to drive the movable bar 208 to slide in the sliding hole 214, so that the movable bar 208 can achieve the sliding effect, and the movable bar 208 will drive the movable pine needle 209 to slide in the limiting sliding hole 215 while sliding, and at the same time make the other roller 211 contact with the fixed plate 212, the continuous movement of the two rollers 211 will make one of the rollers 211 move out from the arc-shaped extrusion block 213, and the other roller 211 will be squeezed by the arc-shaped extrusion block 213, and so on, so that the movable bar 208 can achieve the effect of reciprocating sliding, and then the movable pine needle 209 can slide back and forth, Since cotton is inserted into both the movable pine needle 209 and the fixed pine needle 207, the inserted cotton can be repeatedly pulled during the reciprocating movement of the movable pine needle 209 to tear the cotton apart, thereby improving the loosening effect and facilitating the separation of impurities in the cotton. The fallen impurities will pass through the filter plate 300 and fall into the collection bin 301 for recycling and cleaning. The cotton will move to the position of the connecting roller 401 under the continuous driving of the movable pine needle 209 and the fixed pine needle 207, and will drive the second linkage pulley 409 to rotate during the continuous rotation of the support shaft 203. The rotating second linkage pulley 409 will drive the second driven pulley 411 to rotate by cooperating with the second belt 410, so that the rotating second driven pulley 411 drives the linkage shaft 400 to rotate.Then, the rotating linkage shaft 400 drives the connecting roller 401 to rotate, and the connecting roller 401 drives the brush bar 402 to rotate, so that the rotating brush bar 402 brushes off the cotton on the fixed pine needles 207 and the movable pine needles 209, and makes it fall into the cotton feeder 100 through the discharge port 217. During the rotation process, the brush bar 402 contacts the combing rod 404, and the combing rod 404 can comb off the cotton adhering to the brush bar 402.
