The transmission part 5b is provided with a transmission body 22, the bottom of the transmission body 22 is fixedly connected with the transmission part 5b, the top of the transmission body 22 is hinged with a fluff scraping arm 23, the top end of the fluff scraping arm 23 is hinged with the transmission body 22, the bottom end of the fluff scraping arm is connected with the end part of the scraper 8, the scraper 8 is arranged in an inclined shape, and the bottom end of the scraper 8 is attached to the cleaning fluff sleeve 7.
The first air suction cover 9 is of a cover-shaped structure with a small top and a large bottom, the first air suction cover 9 comprises four cover walls 24 which are sequentially connected end to end, the cover walls 24 are trapezoidal, a fluff cleaning hole 25 is formed in each cover wall 24, two L-shaped supporting pieces 26 are oppositely arranged on the cover walls 24 at two sides of the fluff cleaning hole 25, a blocking plate 27 is arranged at one side of each supporting piece 26, which is far away from the cover wall 24, a fluff cleaning plate 28 is separately arranged between the two supporting pieces 26, when the fluff cleaning plate 28 is arranged between the two supporting pieces 26, the periphery of one side of the fluff cleaning plate 28 is attached to the cover wall 24 at the periphery of the fluff cleaning hole 25, and the other side of the fluff cleaning plate 28 is attached to the blocking plate 27.
One end of the fluff cleaning plate 28 is provided with a U-shaped fluff cleaning handle 29, and two ends of the fluff cleaning handle 29 are connected with the fluff cleaning plate 28. The lint cleaning plate 28 is made of a transparent material, and can be made of a transparent plastic material or a glass material, so that a worker can observe short lint and flying debris on the scraper 8 through the lint cleaning plate 28 and can quickly clean the short lint and flying debris when the short lint and flying debris need to be cleaned.
The utility model provides a drafting device of drawing frame with cleaning structure, when the drafting device works, firstly, the roller 2 drives the leather roller 3 to rotate together, then the driving mechanism also drives the cleaning core shaft 5 to rotate, the cleaning core shaft 5 drives the cleaning wool sleeve 7, and the supporting core shaft 6 is driven to rotate through the cleaning wool sleeve 7; the cleaning velvet sleeve 7 is movably abutted against the surface of the leather roller 3, so that part of short velvet and flying flowers can be adsorbed onto the cleaning velvet sleeve 7 by the cleaning velvet sleeve 7 and then are relatively concentrated at the scraper 8 under the action of the scraper 8, and then the first air suction cover 9 generates negative pressure to suck the short velvet and flying flowers at the scraper 8 away (the air suction cover can also suck the short velvet and flying flowers on the cleaning velvet sleeve 7 away in the process), so that the cleaning velvet sleeve 7 can be kept in a clean state all the time and the leather roller 3 can be cleaned; at the same time, the second air suction hood 10 generates negative pressure, so that air flows, and short fibers and flying fibers adhered to the lower side of the cleaning fiber sleeve 7 can be taken away by the flowing air (the short fibers and flying fibers can fall into the second air suction hood 10 after being separated from the cleaning fiber sleeve 7 under the action of gravity), and are sucked away from the second air suction hood 10.
Wherein, because the cleaning pile cover 7 has a larger cleaning surface area relative to the leather roller 3 (according to the actual situation, one cleaning pile cover 7 can simultaneously clean a plurality of leather rollers 3), when a part of the cleaning pile cover 7 is adhered with short piles and flies, the part of the cleaning pile cover 7 can be rotated to other places, so that the cleaner cleaning pile cover 7 can clean the leather roller 3, and thus, the leather roller 3 can be better cleaned.
When the roller 2 rotates, the driving shaft 11 and the driving teeth 12 are driven to rotate at the same time, the driving teeth 12 sequentially drive the first driving teeth 16, the first driving rod 14, the second driving teeth 17, the third driving teeth 18, the second driving rod 15 and the fourth driving teeth 19 to rotate through meshing action, and due to the size relationship among a plurality of gears, the rotating speed of the driving shaft 11 can be greatly reduced (speed reducer principle), wherein the roller 2 and the leather roller 3 have higher rotating speeds, and the cleaning wool cover 7 does not need to have a very large rotating speed, so that the cleaning wool cover 7 can have a smaller rotating speed through the driving mechanism, and meanwhile, the cleaning wool cover 7 can better clean the surface of the leather roller 3 due to the fact that a large speed difference exists between the cleaning wool cover 7 and the leather roller 3.
Moreover, the fourth driving gear 19 is circularly rotated, but the fourth driving gear 19 drives the driving part 5b to rotate in a reciprocating manner through the driving rocker arm 20 and the movable swing arm 21, and meanwhile, because the driving part 5b and the supporting part 5a are connected through a driving ratchet (ratchet wheel), when the driving part 5b swings in a reciprocating manner, the supporting part 5a only rotates along a certain specific direction, so that the cleaning lint cover 7 at the same position is prevented from repeatedly adsorbing the leather roller 3 (the leather roller 3 and the cleaning lint cover 7 are in a slight contact state, so that the rotating acting force applied to the cleaning lint cover 7 by the rotation of the leather roller 3 can be ignored, and the cleaning lint cover 7 is mainly driven to rotate under the tensioning supporting effect through the supporting part 5 a). Wherein the use direction of the transmission ratchet wheel can be selected according to the situation, so that the rotation directions of the cleaning fluff sheath 7 and the leather roller 3 are the same or opposite.
With the rotation of the cleaning fluff sleeve 7, the cleaning fluff sleeve 7 with short fluff and flying cotton moves to the scraper 8, and the scraper 8 is attached to the surface of the cleaning fluff sleeve 7, so that a part of the short fluff and flying cotton can be intercepted from the cleaning fluff sleeve 7 and then sucked away by the first air suction hood 9, thereby cleaning the cleaning fluff sleeve 7 by the scraper 8. When the transmission part 5b swings back and forth, the transmission body 22 also swings back and forth, and simultaneously drives the fluff scraping arm 23 to swing back and forth, but even if the fluff scraping arm 23 swings back and forth, the scraper 8 at the end part can still keep the state of being attached to the cleaning fluff sleeve 7 under the action of gravity, and the scraper 8 can continuously act. The scraper 8 is inclined (or L-shaped in the drawing), and the inclined direction of the scraper 8 is opposite to the moving direction of the upper part of the cleaning fluff sleeve 7 (for example, the upper part of the cleaning fluff sleeve 7 moves to the left, the bottom of the scraper 8 abuts against the cleaning fluff sleeve 7, and the top is inclined to the upper right), so that the scraper 8 can form a certain included angle with the short fluff and the flying cotton wool, and the scraping effect on the short fluff and the flying cotton wool is better.
When a lot of short fibers and flying fibers are accumulated on the scraper 8 and need to be cleaned, the lint cleaning plate 28 is firstly taken down from the cover body wall 24 through the lint cleaning handle 29, and then the scraper 8 can be cleaned through the lint cleaning hole 25; after cleaning, the lint cleaning board 28 is clamped on the cover body wall 24. When the first air suction cover 9 works, the interior of the first air suction cover 9 is in negative pressure, and the periphery of the fluff cleaning plate 28 blocks the fluff cleaning holes 25 at the moment, so that external air is prevented from entering the first air suction cover 9 through the fluff cleaning holes 25, and the air suction cover can work normally; meanwhile, the two sides of the lint cleaning plate 28 are limited by the cover wall 24 and the blocking plate 27 respectively, and cannot slide off the cover wall 24, so that the position stability of the lint cleaning plate 28 is improved.
