Изобретение относитс к текстильному машиностроению и касаетс машин дл чесани луб ных волокон.The invention relates to textile machinery and concerns machines for combing bast fibers.

Известна налична чесальна машина, в которой дл снижени выпадани пр домых волокон в угары примен ютс поддерживаюшие барабанчики, расположенные в нижней зоне главного барабана под рабочими парами валиков 1.A well-known carding machine in which support drums located in the lower zone of the main drum under the working pairs of rollers 1 are used to reduce the loss of the right fibers in the waste.

Однако в известной машине очистка волокнистой массы вл етс недостаточно качественной, так как поддерживающие барабанчики преп тствуют свободному выбросу костры и непр домых примесей. Кроме того, не исключаетс возможность заматывани поддерживаюших барабанчиков волокном, что приводит к поломке гарнитуры .However, in a known machine, the cleaning of the pulp is not of sufficient quality, since the supporting drums prevent the free release of bonfires and indirect impurities. In addition, the possibility of the supporting drums being wound with fiber is not excluded, which causes the headset to break.

Цель изобретени - повышение производительности путем увеличени выхода длинного волокна и более эффективной его очистки.The purpose of the invention is to increase productivity by increasing the yield of long fiber and more efficient cleaning.

Указанна цель достигаетс тем, что в чесальной машине дл луб ных волокон, содержащей приемный узел, главный барабан с расположенными вокруг него парами рабочих и чистительных валиков и поддерживающие барабанчики, установленные под главным барабаном на рассто нии от последнего и рабочих валиков и с возможностью вращени в одном направлении с главным барабаном, каждый поддерживающий барабанчик расположен между соседними парами рабочих и чистительных, валиков , при этом рассто ние от его поверхности до поверхности главного барабана не более, а до поверхности соответствующего рабочего валика не менее длины корот10 ких волокон.This goal is achieved by the fact that in a carding machine for bast fibers containing a receiving unit, a main drum with a pair of working and cleaning rollers arranged around it and supporting drums mounted under the main drum at a distance from the latter and working rollers and rotatably in one direction with the main drum, each supporting drum is located between adjacent pairs of working and cleaning rollers, while the distance from its surface to the surface of the main drum not more, but the surface of the corresponding working roller is not less than the length of short fibers.

Поддерживающие барабанчики имеют игольчатую гарнитуру.The supporting drums have a needle headset.

На фиг. 1 изображена схема чесальной машины дл луб ных волокон; на фиг. 2 15 вариант исполнени поддерживающего барабанчика .FIG. 1 is a schematic diagram of a punching carding machine; in fig. 2 15 version of the supporting drum.

Чесальна машина содержит приемный узел 1, главный барабан 2 с расположенными вокруг него парами рабочих и чистительных валиков 3 и 4 и поддерживаю20 щие барабанчики 5.The chesnale machine contains a receiving unit 1, a main drum 2 with pairs of working and cleaning rollers 3 and 4 arranged around it and supporting drums 5.

Claims

In the process of carving, part of the pulp from the main drum 2 passes to the working roller 3. The fiber from the working roller 3 is removed by the cleaning roller 4 and transferred to the main drum 2. In the transition zone of the fiber from the roller 3 to the roller 4, the fiber layer is thinned rollers. Under the action of centrifugal forces, unimpeded loss of fires and indirect impurities occurs. In roller carding machines, fiber debris occurs mainly from the main drum and cleaning rollers under the action of centrifugal forces and turbulence of air flow, arising from vrash, the main drum and cleaning rollers. This is manifested to a greater extent, the further apart is the pair of working and cleaning rollers. With a sufficiently close arrangement of the working pairs of the rollers, the collision of long fibers carried by the working and cleaning rollers of the adjacent pairs occurs, as a result of which the fiber also collapses into waste. Therefore, the supporting drums 5 are located in the lower zone of combing the fibers at the main drum between the pairs of working and cleaning rollers in such a way that the distance from the surface of the drum to the surface of the main drum is not more than the surface of the corresponding working roller not less than the length of short fibers, and they are installed rotatably in one direction with the main drum. Installing the supporting drums in the specified place allows freeing the space under the lower pairs of working and cleaning rollers, separating the working and cleaning rollers of the neighboring working pairs, reducing the vortices of air streams arising from the rotation of the working bodies of the carding machine. direction with the main drum contributes to the separation and removal of fires and indirect impurities from the cicadium node, preventing the loss of fibers in the waste, as supporting drums 111) and delay accompany the fibrous streams of cleaning and working rollers. The location of the supporting drums in the immediate vicinity of the needle-like surface of the main drum eliminates the possibility of wrapping them with fiber. The effect of separating campfires and indirect impurities from the fiber and removing them from the cardi nodule increases when the supporting drums are equipped with a needle-type headset. In this case, as a result of the interaction of the fibers with the headset of the supporting drum, the free ends of the fibers are maintained. In addition, the detrusion of long fibers is reduced to waste. Claim 1. A cinder for fiber fibers containing a receiving unit, a main drum with pairs of working and cleaning rollers arranged around it and supporting drums mounted under the main drum at a distance from the latter and working rollers and rotatably in one direction with the main drum, characterized in that, in order to increase productivity by increasing the yield of long fiber and more efficient cleaning, each supporting drum is located between gray pairs of working and cleaning rollers, while the distance from its surface to the surface of the main drum is no more, and the surface of the corresponding working roller is not less than the length of short fibers.

2. The machine according to claim 1, characterized in that the supporting drums have a needle-type headset. Sources of information taken into account during the examination 1. Sidorov MI General technologies of processing of bast fibers. M., 1980, p. 116-119.
