In the process that the seed cotton advances along the guide plate, when the seed cotton passes through the lower suction opening area of the film suction air duct 36, the seed cotton is very loose, uniform and continuous, the seed cotton and the flaky film are in a complete free state, and the film is the best state for being efficiently separated from the seed cotton through air flow. If the structure is not additionally arranged at the position, special residual film cleaning equipment needs to be additionally arranged on an embossing process production line, the manufacturing cost is high, the space of a plant is large, the power consumption is high, and the residual film cleaning efficiency is low correspondingly.

The film is removed by wind power in a complete free state, the efficiency is high, the structure is very simple due to the additional arrangement of the film removing structure, the manufacturing cost is low, the power consumption is low, but the film removing efficiency is high, compared with the traditional special film cleaning equipment, the film removing efficiency can be improved by 50%, the investment can be saved by 80%, the power consumption can be saved by 95%, and the labor is half and twice. Wherein the wind speed in the lower suction port area of the film suction duct 36 needs to be higher than the suspension speed of the film and lower than the suspension speed of the seed cotton to ensure that the film is efficiently removed while the loss of the seed cotton is reduced. The wind power adjusting device can change the wind speed in the film suction air channel 36 according to the suspension speed required by the residual films with different thicknesses or states, so that the internal wind speed exceeds the suspension speed of the residual films and is less than the suspension speed of the seed cotton, and the residual films are effectively adsorbed and removed.

Compared with the dust suction device of the traditional cotton gin, the film suction duct 36 changes the position of a suction port, and increases the wind speed at the suction port, so that the wind speed at the suction port is higher than the suspension speed of the film but lower than the suspension speed of the seed cotton, the film can be separated from the seed cotton, and the separated film enters the upper side duct and is discharged out of the cotton gin. In this process, the dust can also be removed more effectively. After the air quantity is increased, the matched air suction pipe diameter is also correspondingly increased, and because the seed cotton is cleaned for a plurality of times before the cotton is ginned, the seed cotton is very loose and uniform when entering the ginning machine, most of thin films mixed in the seed cotton are changed into smaller sheet-shaped thin films, the thin films are in a free state in the seed cotton, and the affinity with the seed cotton is minimum, so that a thin film cleaning device is arranged at the position, and the optimal residual film cleaning effect can be obtained with small investment.

The working process and the working principle of the cotton gin are as follows:

the seed cotton in the cotton box 1 is fed into the machine through a pair of cotton feeding rollers 2 driven by a variable speed motor, firstly, the seed cotton is loosened and discharged by one to five barbed nail rollers and falls on an upper U-shaped rack roller 6, the bulked seed cotton and a film are easily held by sawteeth due to the combined action of rotating sawteeth and a steel wire brush 5, the bulked seed cotton and the film continue to move forward along the rotating direction of the upper U-shaped rack roller 6, and part of the seed cotton, cotton stalks, boll shells and cotton leaf impurities and stiff petals are not easily or not easily taken by the sawteeth, the seed cotton and the like are thrown out of gaps between two adjacent dust rods 8 through the friction impact of the dust rods 8 under the action of centrifugal force and fall on a lower U-shaped rack roller 9, and part of the impurities and the seed cotton are recovered under the combined action of the U-shaped rack roller 9, the steel wire brush 5, the lower rod 8 of the lower U-shaped rack roller 9 and grid bars 4, and the impurities and the like fall out of an auger discharging machine. Seed cotton and a film hooked by the upper U-shaped rack roller 6 and the lower U-shaped rack roller 9 are uniformly and loosely thrown onto the lower surface of the upper guide plate 11 in front of the seed cotton under the action of the high-speed cotton brushing roller 10, and continue to move forwards under the action of inertia, and when the seed cotton and the film pass through an air suction area, the air speed is higher than the suspension speed of the film due to the upward design of the air suction opening, and the film is easy to be sucked away by wind due to light specific gravity and small inertia, enters the film suction air duct 36, then enters the air suction pipe 18, and then enters the film suction fan to be discharged out of the machine. The clean seed cotton after being subjected to membrane removal cannot change the movement direction by a small wind speed with the wind speed only higher than the suspension speed of the film due to large specific gravity and large inertia, and is guided into the lower guide plate 12 in front of the seed cotton, is thrown downwards to the cotton dripping plate 19 and enters the lower ginning part. Seed cotton enters the front box of the cotton gin under the action of gravity and slides onto the cotton shifting roller 27 along the guide plate, and due to the rotation of the cotton shifting roller 27, the seed cotton is thrown to the outer surface of the saw shaft assembly 25, is taken by saw blade sawtooth hooks and enters the middle box through the shell blocking ribs 26. The middle box is composed of embossing ribs 23, a chest plate 20, a holding plate 21, a cotton seed comb 24, a seed discharge pipe 22 and the like. The seed cotton entering the middle box forms a lap rotating motion under the hooking action of the saw shaft assembly 25, when the fiber hooked by the saw shaft assembly 25 reaches the working point of the rib 23, because the cotton seeds are blocked by the small gaps of the two adjacent assistant bars 23, the cotton seeds can not pass through, but only the fiber can pass through, thereby realizing the separation of the fiber and the cotton seeds. The unginned or ginned cotton seeds move to the breast board 20 and the locking plate 21 along with the cotton rolls under the extrusion pushing of the subsequent seed cotton and then rotate to the cotton seed comb 24, the teeth of the teeth at the transition position of the cotton seed comb 24 and the saw shaft assembly 25 are hooked and sorted according to the fiber content of the cotton seeds, and the unginned wool cotton seeds are pulled by the teeth of the teeth again to realize the separation of the fibers and the cotton seeds again. The smooth cotton seeds meeting the discharge standard are not easy to be pulled by the saw tooth hook due to less fiber, and have small adhesive force with the cotton rolls, and fall into a seed discharge channel formed between the ginning rib 23 and the shell blocking rib 26 under the action of gravity to be discharged out of the machine through the seed discharge plate 28, so that the separation of the smooth cotton seeds and the cotton rolls is realized. The cotton fiber separated from the cotton seeds at two adjacent ribs 23 is rotated out of the cotton roll along with the rotating saw shaft assembly 25, then partial impurities are discharged when passing through the upper impurity discharging plate 31, and the partial impurities are scraped into the saw blade impurity discharging auger 33 to be discharged out of the machine through the impurity discharging scraping plate group 32. The cotton fiber hooked by the saw shaft component 25 is brushed out of the dents under the blowing action of the bristles of the brush assembly 30, so that the separation of the fiber and the sawteeth is realized, part of impurities in the cotton fiber are discharged through the lower impurity discharge plate 29 under the action of inertia force, and the fiber is sent to a lint passage along with the wind power generated by the brush assembly 30 and enters the next working procedure.

Further, the specific structure of the film suction air duct 36 may have various forms, in order to facilitate separation of the plastic film in the seed cotton and prevent the seed cotton from being sucked into the film suction air duct 36 by mistake, and the seed cotton can smoothly enter the saw-tooth embossing cotton brushing part, preferably, as shown in fig. 1, the film suction air duct 36 includes an air duct right lower plate 13, an air duct right upper plate 15, an air duct left lower plate 16, an air duct left upper plate 17 and side plates arranged on two sides, and the plates are connected to form a relatively closed channel, so that separation and suction of the seed cotton and the plastic film can be realized under the action of air flow, and further, the plastic film can be removed. Wherein the lower extreme of wind channel right side hypoplastron 13 is connected with lower guide plate 12 before the seed cotton, the upper end of wind channel right side hypoplastron 13 is connected with the lower extreme of wind channel right side upper plate 15, the upper end of wind channel right side upper plate 15 is connected with plastic film residue aspiration channel 18, the lower extreme of wind channel left side hypoplastron 16 is connected with upper guide plate 11 before the seed cotton, the upper end of wind channel left side hypoplastron 16 is connected with the lower extreme of wind channel left side upper plate 17, the upper end of wind channel left side upper plate 17 is connected with plastic film residue aspiration channel 18, plastic film residue aspiration channel 18 then is connected with the fan, the fan provides negative pressure air current for the passageway is inside, in order to realize the attraction to the film.

Furthermore, the area of the cross section of the lower end of the film absorbing air duct 36 is larger than that of the cross section of the upper end of the film absorbing air duct, and the film absorbing air duct is in a horn shape with a large lower part and a small upper part, so that the film in the seed cotton is more conveniently absorbed into the film absorbing air duct 36, and the separation and removal of the film are realized.

Further, in order to adjust the wind speed in the film suction duct 36 so as to adapt to the suspension speed of different types of films, as shown in fig. 2-5, the wind power adjusting device includes an adjusting plate 14 installed in the film suction duct 36, one end of the adjusting plate 14 is hinged to a side plate of the film suction duct 36, the other end of the adjusting plate 14 is installed with a horizontally arranged adjusting rod 38, and the rotation of the adjusting plate 14 can change the volume of the air flow passing through the film suction duct 36. An arc-shaped groove 39 matched with the adjusting rod 38 is formed in a side plate of the film suction air duct 36, screw rods 40 are arranged at two ends of the adjusting rod 38 penetrating out of the arc-shaped groove 39, and nuts 41 are arranged on the screw rods 40 in a matched mode.

The screw 40 and the adjusting rod 38 can drive the adjusting plate 14 to rotate within the range of the arc-shaped groove 39, so that the size of the air passing area in the film suction air duct 36 can be adjusted as required, after the adjustment is finished, the adjusting rod 38 can be positioned and locked in the arc-shaped groove 39 by rotating the nuts 41 on two sides, so that the adjusting plate 14 is locked, and when the wind speed adjustment is required to be performed according to different types of films, the adjusting rod 38 can be rotated only by loosening the nuts 41. In order to prevent the arc-shaped groove 39 formed in the wind power adjusting device from generating air leakage to the maximum extent and ensure that the plastic film can be sucked and removed by the negative pressure of the air flow in the film suction air duct 36, the blocking piece 37 is sleeved on the periphery of the screw 40 between the nut 41 and the side plate, and the blocking piece 37 can block the arc-shaped groove 39 no matter the screw 40 is positioned at any position in the arc-shaped groove 39, so that the air leakage phenomenon at the position of the arc-shaped groove 39 is effectively prevented, and the normal operation of film adsorption and removal operation is ensured.
