Description
Przedmiotem wynalazku jest urzadzenie do przedzenia tekstylnych wlókien, wyposazone w dwa blisko obok siebie umieszczone perferowane bebny ssace obracajace sie w tym samym kierunku, w obszarze klinowym tych bebnów znajduja sie zwrócone do siebie strefy zasysania, przy czym doprowadzane rozluznione wlókna zostaja w obszarze klinowym skrecone, a powstala przedza zostaje odciagnieta od strony czolowej bebnów przy równoczesnym wstrzymaniu skrecania.The subject of the invention is a device for inserting textile fibers, provided with two close points Peripheral suction drums arranged side by side, rotating in the same direction, in the wedge area These drums have suction zones facing each other, with loosened fibers fed are twisted in the wedge area, and the resulting core is pulled away from the front side of the drums at simultaneously stopping turning.
Urzadzenie takie jest znane z opisu patentowego RFN nr 2449583. W tym rozwiazaniu wystepuja trud¬ nosci, gdy chodzi o produkcje cienkich przedzy, zwlaszcza z bawelny o maksymalnej dlugosci wlókna 50 mm, które sa bardzo elastyczne i cienkie, wskutek czego latwo zatrzymuja sie w otworach bebnów wzglednie zostaja przez te otwory zasysane. Ponadto w przypadku takich wlókien tarcie o beben jest przewaznie zbyt wielkie, aby mozna bylo osiagnac dobre wzajemne skrecenie, wzglednie dobry wyprzed.Such a device is known from the German patent specification No. 2,449,583. This solution is difficult to carrying, when it comes to the production of thin yarns, especially cotton with a fiber length of up to 50 mm, which are very flexible and thin, as a result of which they easily stop in the holes of the drums or remain sucked through these holes. Moreover, with such fibers the friction against the drum is usually too great to be it was possible to achieve good mutual curvature, relatively good lead.
Celem wynalazku jest takie udoskonalenie urzadzenia, aby nadawalo sie ono do wytwarzania cienkich przedz, zwlaszcza z bawelny.The object of the invention is to improve the device so that it is suitable for the production of thin compartment, especially made of cotton.
Urzadzenie wedlug wynalazku charakteryzuje sie tym, ze otwory perferowanej powierzchni bebnów stano¬ wia okolo 20 do 50% ogólnej powierzchni, p:zy czym srednica otworów wynosi maksymalnie 1 mm.The device according to the invention is characterized in that the openings of the perforated surface of the drums are it accounts for approximately 20 to 50% of the total area, p: whereby the maximum diameter of the holes is 1 mm.
Okazalo sie, ze przy tak drobnych otworach bebna niebezpieczenstwo zasysania wlókien przestaje istniec, a tarcie miedzy wlóknami i perferowanymi powierzchniami bebnów zostaje do tego stopnia zredukowane, ze mozliwe sie staje doskonale wzajemne skrecenie, wzgledny wyprzed. Sumaryczna powierzchnia otworów w bebnach musi przy tym miescic sie w podanym zakresie, gdyz w przeciwnym razie przenoszacy wlókna strumien powietrza odprowadza za malo powietrza i moga wystapic spietrzenia, wzglednie wiry, wplywajace ujemnie na jakosc przedzy.It turned out that with such small holes in the drum, the danger of sucking in fibers ceases to exist, and the friction between the fibers and the peripheral surfaces of the drums is reduced to such an extent that a perfect mutual twist, relative advance becomes possible. Total area of the holes must be within the specified range in the drums, otherwise the transmission fibers the air stream discharges too little air and there may be damming or vortices, the quality of the yarns.
Przedmiot wynalazku jest objasniony w przykladzie wykonania na rysunku, który przedstawia istotne czesci urzadzenia w przekroju plaszczyzna pionowa.The subject matter of the invention is explained in an exemplary embodiment in the drawing which shows the essentials parts of the device in a cross section - a vertical plane.
Dwa blisko siebie umieszczone i obracajace sie w tym samym kierunku perforowane ssace bebny 1, 2 maja kazdy po jednej ssacej wkladce 3, 4. Ssace wkladki tworza w obszarze klinowym miedzy ssacymi bebnami 1, 2 zwrócone do siebie strefy zasysania 5, 6. Po stronie czolowej bebnów znajduje sie para walków odciagajacych 7,2 104526 które tworzaca sie przedze odciagaja w kierunku dlugosci bebnów z jednoczesnym wstrzymaniem skrecania.Two perforated suction drums close together and rotating in the same direction on May 1, 2 each suction pad 3, 4. suction pads form in the wedge area between the suction drums 1, 2 suction zones 5, 6 facing each other. On the front side of the drums there is a pair of draft rollers 7.2 104526 which form the fore, pull towards the length of the drums while stopping turning.
Wlókna dostarczane sa przez urzadzenie rozlókniajace, skladajace sie z walków 8 doprowadzajacych material oraz z bebna 9 rozwlókniajacego majacego obicie zgrzebne na swej powierzchni, z którego wlókna przechodza bezposrednio w obszar klinowy pomiedzy ssacymi bebnami 1, 2 z tym, ze powietrzna dysza 10 zapewnia odpo¬ wiedni strumien powietrza do przenoszenia wlókien.The fibers are delivered by a disintegrator, consisting of rollers 8 for feeding the material and from a fiberising drum 9 having a carded covering on its surface, from which the fibers pass directly into the wedge area between the suction drums 1, 2, but the air nozzle 10 ensures an adequate air stream to convey the fibers.
Obydwa ssace bebny 1, 2 maja wiele otworów na swej powierzchni, które stanowia okolo 20 do 50% ogólnej powierzchni bebnów, przy czym srednica otworów nie przekracza 1 mm. Przy tych wymiarach urzadze¬ nie nadaje sie do wytwarzania cienkich przedzy z bawelny.Both suction drums 1, 2 have many holes on their surface, which account for about 20 to 50% the overall surface of the drums, with the hole diameter not exceeding 1 mm. With these dimensions, the equipment not suitable for making thin cotton yarns.
