Description

Изобретение относитс к машиностроению текстильной -промышленности и может быть использовано дл первоначального нат жени нити в шпул рниках нитетрактов.The invention relates to the mechanical engineering of the textile industry and can be used for the initial tension of the thread in the nittract spools.
Известен нат житель нити, содержаший установленный в опоре пустотелый ролик, частично заполненный сыпучим материалом и охватываемый нитью 1.A thread tensioner is known, containing a hollow roller installed in a support, partially filled with a bulk material and covered by thread 1.
Недостатком такого нат жител вл етс разрушение волокон нат гиваемой- нити из-за наматывани ее на барабан (ролик) по винтовой линии, что ведет к наползанию витков друг на друга и скольжению нити вдоль образуюш,ей барабана.The disadvantage of such a tensioner is the destruction of the fibers of the stretchable yarn due to its winding on the drum (roller) along a helical line, which leads to the crawling of the coils on each other and sliding of the yarn along with the drum.
Цель изобретени - повышение надежности нат жени нити.The purpose of the invention is to increase the reliability of the thread tension.
Это достигаетс тем, что опора имеет два пустотелых валика, частично заполненных сыпучим материалом, оси которых параллельны оси ролика.This is achieved in that the support has two hollow rollers, partially filled with bulk material, the axes of which are parallel to the axis of the roller.
. На чертеже изображен предлагае.мый нат житель .. The drawing shows the proposed tensioner.
Нат житель нити содержит корпус 1, с помош,ью которого он крепитс на шпул рнике , три пустотелых валика, частично заполненных стальными шариками или сыпучим материалом 2. Два валика 3 свободно установлены на параллельных ос х 4, а третий валик 5 свободно на них лежит.Thread tensioner contains body 1, with the aid of which it is attached to the spool, three hollow rollers partially filled with steel balls or bulk material 2. Two rollers 3 are freely mounted on parallel axes x 4, and the third roller 5 is free on them .
.Нат гиваема нить укладываетс на валики 3 и прижимаетс к ним валиком 5, обеспечива кинематическую св зь валиков 3.A tension thread is laid on the rollers 3 and pressed against them by the roller 5, providing a kinematic connection of the rollers 3.
Суммарный угол обхвата валиков 3 и 5 нитью и заш.емление ее между ними обеспечивает усилие трени между нитью и их поверхност ми больше .усили проворота кинематически св занных валиков.The total angle of circumference of the rollers 3 and 5 with the thread and the patching of it between them provides the force of friction between the thread and their surfaces, due to more twisting of the kinematically connected rollers.
При равномерной скорости движени нити валики наход тс в кинематической св зи . Тормозной момент создаетс за счет отклонени центра т жести валиков от устойчивого вертикального положени .At a uniform speed of movement of the thread, the rollers are in kinematic connection. The braking torque is created by the deviation of the center of gravity of the rollers from a stable vertical position.
При изменении скорости движени ни20 ти усилие нат жител остаетс практически посто нным из-за незначительного изменени проекци радиуса приложени центра т жести валиков на горизонтальную плоскость .When you change the speed of movement of the tension of the tensioner, the force remains almost constant due to a slight change in the projection of the radius of application of the center of gravity of the rollers to the horizontal plane.
