The elastic buffer assembly 233 is fixed to the upper end of the first mounting bracket 232. The front and rear ends of the first cotton-feeding roller 235 are rotatably mounted on the elastic telescopic ends of the elastic buffer assembly 233. The second cotton-feeding roller 236 is rotatably mounted on the first mounting bracket 232 and corresponds to the lower side of the first cotton-feeding roller 235. The first cotton-guiding roller 234 is rotatably mounted on the second frame 21 and corresponds to the upper side of the left end of the first conveying curtain 22. The second rotation drive assembly 231 is drivingly connected to the first cotton-guiding roller 234, the first cotton-feeding roller 235, and the second cotton-feeding roller 236 through the linkage assembly 237. The third cotton-beating bin 24 and the second cotton-feeding fan 25 are sequentially and fixedly arranged on the left side of the third feeding mechanism 23.
[0021] The cotton material after rough opening is put onto the first conveying curtain 22 through a pipeline or manually, and is conveyed to the left on the first conveying curtain 22. The second rotation drive assembly 231 drives the first cotton-guiding roller 234, the first cotton-feeding roller 235, and the second cotton-feeding roller 236 to rotate. The cotton material is compressed under the action of the first cotton-guiding roller 234 and conveyed between the first cotton-feeding roller 235 and the second cotton-feeding roller 236. The first cotton-feeding roller 235 and the second cotton-feeding roller 236 further compress the cotton material and convey it to the left into the third cotton-beating bin 24 for fine opening. The cotton material after fine opening is conveyed to subsequent equipment by the second cotton-feeding fan 25. The first cotton-feeding roller 235 is mounted on the elastic telescopic end of the elastic buffer assembly 233 and can automatically rise or fall according to the amount of the fed cotton material, so as to avoid excessive pressure on the first cotton-feeding roller 235 and the second cotton-feeding roller 236 when the cotton material piles up, reduce the risk of damage to the first cotton-feeding roller 235 and the second cotton-feeding roller 236, and improve the service life of the equipment.

The fifth synchronous gear 2375 is drivingly connected to the fourth synchronous gear 2374 through a synchronous belt.
[0026] The second rotation drive assembly 231 drives the second cotton feeding roller 236 and the first synchronous gear 2371 to rotate counterclockwise, so that the rotation directions of the second synchronous gear 2372, the third synchronous gear 2373 and the fourth synchronous gear 2374 are clockwise, counterclockwise and clockwise respectively, that is, the rotation direction of the first cotton feeding roller 235 is also clockwise. The fifth synchronous gear 2375 is drivingly connected to the fourth synchronous gear 2374 through a synchronous belt, that is, the rotation directions of the fifth synchronous gear 2375 and the first cotton guiding roller 234 are also clockwise, thereby gradually transporting the cotton material to the left.
[0027] The third cotton beating bin 24 includes a bin body housing 241, a third cotton beating roller 242 and a third rotation drive assembly 243.
