(54) ВЫТЯЖНОЙ ПРИБОР ТЕКСТИЛЬНОЙ МАШИНЫ(54) EXHAUST DEVICE TEXTILE MACHINE

II

Изобретение относитс к текстильной промьшшенности и может быть использовано в пр дильном производстве.This invention relates to the textile industry and can be used in spinning.

Известен выт жной прибор текстильной машины, содержащий выт жные пары рифленых цилиндров с нажимными валиками , установленными на рычагах нагрузки , и смонтированную с возможностью возвратно-поступательного перемещени вдоль линии цилиндров водилку с уплотнител ми волокнистого продукта , св занными попарно один с другим .В приборе предусмотрено, чтобы водилка за каждый ход смещалась на небольшую величину, обеспечивающую возвратно-поступательное смещение продукта вдоль линии цилиндров от центра нажимного валика по обе его стороны и тем самым способствующую равномерному износу покрыти нажимного ва5шка . Уплотнители установлены на средней линии выт жных пар tl.A textile machine exhaust device containing exhaust pairs of corrugated cylinders with pressure rollers mounted on the load levers and mounted with a reciprocating movement along the line of cylinders is a carrier with fiber material seals coupled in pairs with one another. The device provides so that the drive for each stroke is shifted by a small amount, providing reciprocating displacement of the product along the line of cylinders from the center of the pressure roller on both its sides and thereby contributing to uniform wear of the pressure plate cover. Seals are installed on the centerline of the exhaust tl.

Однако рбрывность и неровнота продукта при выт гивании увеличиваетс However, the permeability and unevenness of the product during stretching increases.

;при смещении его к наружным кра м нажимных валиков. Это обусловлено тем что площадка контакта нажимного валика с цилиндром,вследствие изгиба оси нажимного валика неравномерна по его длине. Ширина площадки уменьшаетс от центра выт жной пары к ее наружному концу, вследствие чего уменьшаетс давление и стабильность зажима выт гиваемого продукта. Ближе к внут10 реннему концу пары ширина площадки более равномерна и посто нна.when shifting it to the outer edges of the pressure rollers. This is due to the fact that the contact area of the pressure roller with the cylinder, due to the bending of the axis of the pressure roller, is uneven along its length. The width of the pad decreases from the center of the exhaust pair to its outer end, thereby reducing the pressure and stability of the clamp of the drawable product. Closer to the inner end of the pair, the width of the platform is more uniform and constant.

Целью изобретени вл етс снижение обрывности и повьш1ение качества продукта при его выт гивании.The aim of the invention is to reduce the breakage and improve the quality of the product when it is being drawn.

20 mounted with the possibility of reciprocating movement along the line of cylinders a cage with fiber product seals connected in pairs to one another, the seals of each pair are displaced relative to the average width of the line of the exhaust pair along the pressure roller to one another, while is 0.05-0.10 the length of the elastic coating of the pressure roll. The drawing shows an exhaust device, a general scheme. The spinning machine's exhaust device contains exhaust pairs formed by grooved cylinders 1 and pressure rollers 2 mounted on the load levers 3. Along the line of the rear cylinders, the driver A with the fiber reinforcement 5 installed by means of stops 5 is mounted with reciprocating movement products that are paired with one another. Each seal of each pair is displaced relative to the average width of the line 7 of the exhaust pair in the direction towards the other sealant associated with it, by an amount A, which is 0.05-0.10 the length B of the elastic coating of the pressure roller and, for example, 2-4 mm. The fibrous product, the passage through the slots of the seals 6, enters the clamp of the supply pair 8 of the exhaust device and then stretches between the intermediate 9 and the outlet 10 exhaust pairs. The driver 4, together with the seals 6, makes a reciprocating motion, moving the product along the feed exhaust pair 8. 34 Since the seals are displaced relative to the center line of the exhaust pairs towards each other, the product shifts to the outer end of the pressure roller by an amount less usual 2-4 mm, thus most of the time of the stretching process in the zone of optimum clamping of the exhaust pair. In this way, the breakage is reduced and the quality of the fibrous product is improved when it is drawn. Claims of a textile machine exhaust device containing exhaust pairs of corrugated cylinders with pressure rollers mounted on the load levers and mounted with the possibility of reciprocating along the line of cylinders a carrier with fibrous product seals connected in pairs with one another. The fact that, in order to reduce the breakage and improve the quality of the product when it is being pulled, the seals of each pair are displaced relative to the average width of the line of the exhaust pair along the push One roller to another, with the displacement of each seal being 0.05-0.10 the length of the elastic coating of the pressure roller.
