In addition, in the description process of the embodiment of the present invention, the positional relationships of the devices such as "upper", "lower", "front", "rear", "left", "right", and the like in all the drawings are based on fig. 1.

As shown in fig. 1, a working box of a cotton gin comprises a front embracing device 3, a back chest embracing device 4 and a sawtooth roller 1, wherein the front embracing device 3 and/or the back chest embracing device 4 are/is embracing-jointed to form a rolling working cavity 7, a plurality of rotatable rolling extrusion units 8 which are arranged in a circular arc shape are respectively provided, and a plurality of arc-shaped rolling extrusion surfaces are formed on inner walls of the rolling extrusion units and are used for removing cotton seeds in the cotton seeds.

As can also be seen in fig. 1, the sawtooth rollers 1 are arranged at the bottoms of the front embracing device 3 and the rear chest embracing device 4;

and an embossing rib 2 is arranged between the sawtooth roller 1 and the rear chest cohesion device 4 and is used for separating the trend of the cotton sliver entering the working cavity. A cotton seed comb 6 is further arranged between the bottom of the front holding device 3 and the sawtooth roller 1 so as to separate the combed cotton seeds instantly, and a cotton seed outlet is arranged at the bottom of the working box and can be directly discharged from the cotton seed outlet.

As can be seen from fig. 1, the specific operation of the gin working box is as follows:

before the cotton gin works, a certain amount of seed cotton and the mixture of the seed cotton are put into a working box manually.

During operation, seed cotton enters from the position H, falls onto the cotton dropping plate 9 at the lower part, and flows onto the rotating cotton shifting roller 10 along the cotton dropping plate 9, then the rotating cotton shifting roller is shifted to the position A on the rotating sawtooth roller 1, the seed cotton pulled by the sawtooth hook of the sawtooth roller moves along with the sawtooth roller 1, the seed cotton moves to the position B from the position A, and in the moving process, the seed cotton is simultaneously dragged by the seed cotton roll and blocked by the ginning rib 2, and the fiber bundle pulled by the sawtooth hook is pulled off from the seed cotton.

At the juncture (working point) B of the sawtooth roller 1 and the ginning rib 2, the sawtooth hook of the rotating sawtooth roller 1 pulls seed cotton fibers into the gap of the ginning rib 2, wherein most of the fibers are separated from the cotton seeds, and the seed cotton which is pulled off part of the fibers is blocked in the working box by the ginning rib row 2. Since the saw teeth of the following saw drum 1 continuously leave the seed cotton which is partially defibered above the working roller B, the seed cotton is squeezed tightly here and squeezed upward along the surface of the ginning rib row 2, pushing the previous seed cotton upward. As a result, the seed cotton in zone B moves toward zone C, and then toward zones D and E, resulting in movement of the outer layer of the seed cotton roll in the working bin. When moving to the cotton seed comb 6, the cotton seed comb meets the newly entered seed cotton and is pulled into the B area by the sawtooth hook again. The cotton seeds which are hooked and purified the cotton fibers are discharged out of the machine from the position F. Therefore, cotton fibers and fallen cotton seeds are continuously taken away by the sawteeth of the sawtooth roller 1 and are continuously hooked into new seed cotton for supplement, and the seed cotton of the working box is always in a stable roll state and continuously moves along the inner wall of the working box.

As can be seen from fig. 1, 2 and 4, the length of the cotton seed comb 6 is adapted to the length of the sawtooth roller 1, so as to meet the rolling production requirement of the cotton sliver in the whole working box.
