The raw cotton processed by the condenser 2 enters the feed box 3, and is turned into medium cotton balls through the movement of the slowly rotating cotton opening cutter roller 4. Then, the raw cotton enters the discharge box 5 under the pulling action of the medium-speed rotating roller 6, so that the cotton material discharged from the discharge box 5 is changed from medium cotton balls to small cotton balls, and the cotton is further opened. Finally, the cotton material opened for the second time enters the cotton opening box 7, and the small cotton balls are opened under the action of the high-speed rotating opening beater 8, and the small cotton balls are beaten into loose small cotton blocks, so that the small cotton blocks are output from the discharge box 9 to the next process equipment.

[0022] Example 2: On the basis of Example 1, the input end of the feeding fan 1 is connected to the plucking machine, and the input end of the feeding fan 1 is connected to the input end of the condenser 2 on one side through the connecting pipe 10. The output end at the bottom of the condenser 2 is connected to the feed box 3. The input end of the feeding fan 1 is connected to the plucking machine, so as to facilitate the plucking of the cotton and transfer the raw cotton to the condenser 2, so as to facilitate the processing of the condenser 2. After the processing is completed, the condenser 2 outputs the cotton material to the feed box 3. A support frame plate 11 is fixedly connected to one side wall of the feed box 3, and a reduction motor 1 is fixedly installed on one side of the support frame plate 11. 2. A track groove 13 is provided on the other side of the support frame 11. The track groove 13 is in the shape of "∞". A small gear 14 is fixedly installed on the output end of the reduction motor 12. A support frame 11 is fixedly installed on one side wall of the feed box 3. The support frame 11 and the inner wall of the other side wall of the feed box 3 are provided with a chute. The chute and the track groove 13 are both in the shape of "∞", which facilitates the movement of the cotton cutting roller 4. The reduction motor 12 is fixedly installed on one side of the support frame 11. The reduction motor 12 is stably supported by the support frame 11. The setting of the reduction motor 12 can indirectly slow down the opening The moving speed of the cotton cutting roller 4, the lower side of the pinion 14 is meshed with a driving gear 15, and one side of the driving gear 15 is meshed with a driven gear 16. The driving gear 15 and the driven gear 16 are both rotatably sleeved on the limit column 17, and the limit column 17 is fixedly installed in the support frame plate 11. The surface of the driven gear 16 is provided with a groove 18, and a connecting column 19 is slidably connected in the groove 18. The pinion 14 is meshed with the driving gear 15 for transmission, and the driving gear 15 is meshed with the driven gear 16 for transmission. The driving gear 15 and the driven gear 16 are both rotatably sleeved on the limit column 17. The limiting column 17 is fixedly connected to the support frame plate 11, and the grooves 18 provided on the driving gear 15 and the driven gear 16 are convenient for limiting the connecting column 19. A guide bar 20 is rotatably sleeved on one end of the connecting column 19, and the guide bar 20 is slidingly connected to the track groove 13. The other end of the connecting column 19 is fixedly connected to one end of the cotton opening cutting roller 4, and the other end of the cotton opening cutting roller 4 is slidably installed on the inner wall of the feed box 3. The bottom of the feed box 3 is connected to the discharge box 5. The connecting column 19 moves in the track groove 13 through the guide bar 20, driving the cotton opening cutting roller 4 fixedly connected to it to move.

[0023] The cotton picking machine takes the cotton through the suction of the feeding fan 1, and the raw cotton enters the condenser 2. The condenser 2 can unload the air volume of the feeding fan 1 on the one hand, and remove the impurities and dust in the raw cotton on the other hand, so as to improve the quality of the cotton opening. The raw cotton processed by the condenser 2 enters the feed box 3, and the reduction motor 12 is started. The reduction motor 12 drives the small gear 14 to rotate, and the small gear 14 drives the driving gear 15 and the driven gear 16 to rotate. Under the rotation of the driving gear 15 and the driven gear 16, the raw cotton enters the condenser 2 through the feeding box 3. The groove 18 drives the connecting column 19 to move, and the connecting column 19 is connected to the track groove 13 by the sliding connection between the guide bar 20 rotatably sleeved thereon and the track groove 13, thereby driving the cotton opening cutting roller 4 fixedly connected to the connecting column 19 to move. The knife head on the cotton opening cutting roller 4 is bent, so that the fabric can be opened better. The cotton opening cutting roller 4 moves slowly under the constraint of the "∞" track groove 13 and the slide groove, thereby turning large cotton balls into medium cotton balls, and at the same time avoiding the large connection force between the cotton fibers in the large cotton balls, causing damage to the cotton fibers.

[0024] Example three: On the basis of Example two, a medium-speed motor 21 is fixedly connected to one side wall of the discharge box 5, three rollers 6 are provided and arranged in a linear array, one end of the middle roller 6 is fixedly connected to the main gear 22, and one end of the rollers 6 on both sides is fixedly sleeved with a sub-gear 23, the output end of the medium-speed motor 21 is fixedly connected to one end of the middle roller 6, one end of the loosening beater 8 is fixedly connected to the output end of the high-speed motor 24, the high-speed motor 24 is fixedly installed on one side of the cotton opening box 7, the bottom of the cotton opening box 7 is connected to the discharge box 9, and an air supply fan 25 is fixedly installed on one side of the discharge box 9.

[0025] The middle cotton ball after being opened by the cotton opening cutter roller 4 enters the discharge box 5, and the medium-speed motor 21 fixedly installed on one side of the discharge box 5 is started, so that the medium-speed motor 21 drives the roller 6 in the middle position to rotate. At the same time, the roller 6 in the middle position drives the main gear 22 to rotate, and the main gear 22 is meshed with the sub-gears 23 on both sides thereof, thereby making the rollers 6 on both sides rotate, so that under the rotation action of the three rollers 6, the middle cotton ball is changed into small cotton balls and the small cotton balls are transported downward. After the cotton material has been opened twice, the coupling force between the cotton fibers is the smallest. At this time, by starting the high-speed motor 24, the rotation action of the high-speed motor 24 drives the opening beater 8 to rotate at a high speed, and then under the opening action of the opening beater 8, the small cotton balls are beaten into loose small cotton pieces, so that the small cotton pieces are output from the discharge box 9 to the next process equipment, realizing multi-stage cotton opening while improving the cotton opening quality. Finally, the blowing action of the air supply fan 25 facilitates the small cotton pieces to enter the next process faster.
