[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1 - Figure 7As shown in the figure, the utility model relates to a double-layer saw-tooth lint stripping machine, which comprises a housing 1. Inside the housing 1, a seed feeding roller 2, a seed stripping roller 3, a seed removing assembly 4 and a brush roller 5 are rotatably connected. An inlet 101 is provided on the upper surface of the housing 1, and an outlet 102 is provided on the outer surface of the housing 1. A number of stirring rods 201 are provided on the outer surface of the seed feeding roller 2. A stripping plate 301 is provided on the outer surface of the seed stripping roller 3. Four stripping plates 301 are provided and axially distributed around the seed stripping roller 3;

[0029] The seed removing assembly 4 includes a seed removing roller 401. A number of first saw teeth 402 are provided on the outer surface of the seed removing roller 401. A cavity 403 is provided inside the seed removing roller 401. An air inlet 404 is provided at one end of the seed removing roller 401. A number of mounting grooves 405 are provided on the outer surface of the seed removing roller 401. One end of the mounting groove 405 extends into the cavity 403. A second saw tooth 406 is slidably connected inside the mounting groove 405;

[0030] A valve core 407 is installed inside the air inlet 404. One end of the valve core 407 abuts against a baffle 408. The baffle 408 is slidably connected inside the air inlet 404. A spring 409 is installed at the end of the baffle 408 away from the valve core 407. The other end of the spring 409 is installed with a cover body 4010. An airbag 4011 is installed at the end of the cover body 4010 away from the spring 409. A through hole 4014 is provided on the outer surface of the cover body 4010. The airbag 4011 is installed inside the cavity 403. A second saw tooth 406 is installed on the outer surface of the airbag 4011;

[0031] A dust-proof plug 4012 is installed inside the air inlet 404 in an interference fit manner. A stop block 4013 is provided at one end of the dust-proof plug 4012;

[0032] By injecting gas into the air inlet 404, the gas pushes the baffle 408 through the valve core 407 to compress the spring 409. At the same time, the gas enters the airbag 4011 through the through hole 4014, causing the airbag 4011 to gradually expand. During the expansion process of the airbag 4011, it will push the second saw tooth 406 to move outward in the mounting groove 405. When the outer surface of the airbag 4011 abuts against the inner surface of the cavity 403, stop injecting gas, and the spring 409 will restore its elasticity to push the baffle 408 to reset. At this time, the height of the second saw tooth 406 is slightly higher than that of the first saw tooth 402. During the rotation of the seed removing roller 401, the second saw tooth 406 replaces the first saw tooth 402 to strip the lint from the cotton seeds. By using the first saw tooth 402 and the second saw tooth 406 in cooperation to replace the saw blade disc, it is avoided that the effect of stripping lint from cotton seeds becomes poor after the saw teeth of the saw blade disc are worn;

[0033] One end of the seed feeding roller 2, the seed stripping roller 3, the seed removing roller 401 and the brush roller 5 extends to the outside of the housing 1. One end of the seed stripping roller 3 is equipped with a first driving motor 6, and one end of the brush roller 5 is equipped with a second driving motor 7;

[0034] A first transmission wheel 8 is installed on the outer surface of the brush roller 5, a second transmission wheel 9 and a third transmission wheel 10 are installed on the outer surface of the seed removing roller 401, and a fourth transmission wheel 11 is installed on the outer surface of the seed feeding roller 2. The first transmission wheel 8 is drivingly connected to the second transmission wheel 9 through a first belt 12, and the third transmission wheel 10 is drivingly connected to the fourth transmission wheel 11 through a second belt 13.

[0035] During use, by starting the first driving motor 6 and the second driving motor 7, the output end of the first driving motor 6 drives the seed stripping roller 3 to rotate, and the output end of the second driving motor 7 drives the brush roller 5 to rotate. While the brush roller 5 rotates, it drives the first transmission wheel 8 to rotate, so that the first transmission wheel 8 drives the second transmission wheel 9, the third transmission wheel 10 and the seed removing roller 401 to rotate through the first belt 12. The third transmission wheel 10 drives the fourth transmission wheel 11 and the seed feeding roller 2 to rotate through the second belt 13. Cotton seeds are put into the interior of the housing 1 through the feed inlet 101. The cotton seeds are dispersed by the stirring rod 201. The dispersed cotton seeds fall to the seed stripping roller 3 and are then transmitted to the outer surface of the seed removing roller 401 through the stripping plate 301. The cotton fibers on the cotton seeds are pulled off by the first saw teeth 402 arranged on the outer surface of the seed removing roller 401. Since the first saw teeth 402 are in contact with the brush roller 5, the cotton fibers are separated from the first saw teeth 402. The separated cotton fibers are discharged from the housing 1 through the discharge outlet 102 for collection. When the defluffing effect of the first saw teeth 402 becomes poor, first take out the dust-proof plug 4012 from the interior of the air inlet 404, inject gas into the interior of the air inlet 404, so that the gas pushes the baffle 408 through the valve core 407 to compress the spring 409. At the same time, the gas enters the interior of the airbag 4011 through the through hole 4014, so that the airbag 4011 gradually expands. During the expansion process of the airbag 4011, it will push the second saw teeth 406 to move outward in the installation groove 405. When the outer surface of the airbag 4011 abuts against the inner surface of the cavity 403, stop injecting gas, so that the spring 409 resumes elasticity and pushes the baffle 408 to reset. At this time, the height of the second saw teeth 406 is slightly higher than that of the first saw teeth 402. During the rotation of the seed removing roller 401, the second saw teeth 406 replace the first saw teeth 402 to perform defluffing on the cotton seeds. By using the first saw teeth 402 and the second saw teeth 406 in cooperation, the saw blade disc is replaced, avoiding the deterioration of the defluffing effect on the cotton seeds after the teeth of the saw blade disc are worn.
