The process and principle that the barbed strip roller transfers cotton fibers from the working rollers of the saw-tooth cotton gin, the saw-tooth delinter and the saw-tooth lint cotton cleaner and conveys the cotton fibers out of the machine body are as follows:
when the cotton fibers separated from the working roller reach the intersection with the barbed strip roller, the cotton fibers float on the surface of the working roller under the centrifugal force of the working roller, and because the barbed strip roller is relatively large in diameter, high in linear speed and small in gap with the working roller, the cotton fibers are hooked and pulled by the comb needle rack on the surface of the barbed strip roller at the intersection point, are separated from the working roller and rotate and move along with the barbed strip roller, and the cotton fiber transfer process is completed; the cotton fibers moving along with the barbed strip roller are transferred, and because the rotating centrifugal force of the barbed strip roller is larger than the holding force of the barbed strip roller on the cotton fibers, the cotton fibers are thrown off by the centrifugal force, leave the barbed strip roller and are held by a cotton holding plate arranged at the lower part of the barbed strip roller and blocked by a rear wind shield, and the cotton fibers are thrown out of the machine body from a cotton fiber outlet under the action of the centrifugal force and the centrifugal inertia force.
The low noise and low dust principle when the thorn strip roller operation:
at present, the diameter of a brush roller of a sawtooth cotton gin, a sawtooth linter and a sawtooth lint cotton cleaner is generally about 400mm, the rotating speed is about 1600 revolutions per minute, the working length is about 1.6 meters, and the air volume produced by the brush roller is about 5160m3H; through the utility model human experiment: because the hook pulling force and the holding force of the barbed strip roller to the cotton fiber are obviously greater than those of the brush roller, when the diameter of the barbed strip roller is set at 400mm and the rotating speed is set at 1200 rpm, the barbed strip roller can completely transfer the cotton fiber on the working roller and can convey the cotton fiber out of the machine body; the air quantity generated by the barbed strip roller with the diameter of 400mm, the rotating speed of 1200 rpm and the length of 1.6 meters is about 262m3And h, only about 5 percent of the air volume produced by the brush roller is needed, so that the air speed of the space between the wind shield and the barbed strip layer after passing through is smaller than the linear speed of the surface of the barbed strip roller or the surface of the barbed strip layer, therefore, the force of friction and cutting between the air flow produced by the operation of the barbed strip roller and surrounding mechanical parts is very weak, and noise is hardly generated during operation, and meanwhile, because the air volume sucked by the barbed strip roller during operation is very small, correspondingly, the discharged air containing dust is only about 5 percent of that of the brush roller, so that the air pollution degree is very low.

comparative example 1
Fig. 2, according to present sawtooth gin, sawtooth delinter, sawtooth ginned cotton descaling machine brush roller section of thick bamboo 400 diameter is 310mm, 26 brush 401 of equipartition all around, brush roller section of thick bamboo 400 length 1.6 meters, the speed of rotation 1600 revolutions per minute, the brush cylinder is the lower half week by holding in the palm cotton board 404 parcel, brush 401 height is 50mm and the sum of the height 25mm of brush bundle 410 and brush root 420 promptly, brush roller shell 430 radius is 155mm, single brush bundle thickness is 10mm, single brush root thickness is 25mm, the amount of wind that the clock produced when the brush roller section of thick bamboo work appears can simply be calculated, the computational formula is:
the wind volume Q1 is the wind volume V of the brush roller
The wind volume of the brush roller is as follows:
v ═ area of brush roll profile-area of brush roll housing-area of 26 brush bundles and brush roots } x length of brush roll
＝{3.14*(0.155+0.025+0.025)m2*(0.155+0.025+0.025)m2-3.14*0.15 5m*0.155m-[(0.025*0.025)+(0.01*0.025)]㎡*26}*1.6＝0.054032m3
