The forming device untwisted rovings from flax fiber
(57) Abstract:The invention can be used in spinning textile industry for the formation of untwisted rovings from flax fibers and improves the conditions of formation of the rovings in the exercise of control over the fibers in the sliver on the area between the pair of exhaust and inlet funnel and shorter time-sliver contact with water. The device comprises a reel for sealing sliver and tub to soak sliver. The reel is located between the pair of exhaust and outlet pair to drain Rove. Wetting sliver occurs by capturing water from baths cylinder exhaust vapors to dissipate Rove. 1 Il. The invention relates to spinning textile industry and relates to a device for forming Rove from flax fiber.In the process of yarn production from natural fibers is formed of a fibrous product (tape) with a constant weight (linear density). To produce yarn this semi-finished product goes through several stages of drawing, with its linear density decreases. The product of the linear density of 0.25-2 ktex (rovings) is formed by the flyer. It has two branches, Ki (TRUEVAL N. And. and other Technology and equipment for the textile industry, Moscow, Light industry, 1975).Speed flyers are limited due to the deformation of the branches under the action of centrifugal forces. This leads to the speed limit release and decreased performance roving equipment.This disadvantage is not present in the known device the formation of untwisted rovings containing the input funnel, the water bath, rotating it perforated drum, seal and outlet pair (EN 2148113 C1, 27.04.2000).Sliver of the exhaust device passes through the sealing funnel, is supplied to the surface of the perforated drum, around it a few times, passing through the seal. Because the lower portion of the drum submerged in water, the sliver is moistened. Passing through the seal, sliver is pressed and becomes rounded shape, turning into a roving, which is given final pair.However, when forming the Rove machine sliver in the area from the exhaust vapors to the inlet funnel is uncontrolled and the result of electrostatic forces, shoves, which leads to the accumulation of fibers on the exhaust roller and the increase in inequality is the amount of time and absorb large amounts of water, which flows from the package during storage.The closest analogue is the forming device untwisted rovings from flax fibers, containing reel to seal sliver and tub to soak sliver (DE 737706 AND 21.07.1943).However, in this device are not provided optimal conditions for the formation of Rove.The objective of the invention is to provide a device of forming untwisted rovings of flax fiber, providing technical result consists in the improvement of the conditions of formation of the rovings in the exercise of control over the fibers in the sliver on the area between the pair of exhaust and inlet funnel and shorter time-sliver contact with water.This technical result in the forming device untwisted rovings from flax fibers, containing reel to seal sliver and tub to soak sliver, is achieved by the fact that the reel is located between the pair of exhaust and outlet pair to drain Rove and wetting sliver occurs by capturing water from baths cylinder exhaust vapors to dissipate Rove.The drawing shows a diagram of the device forming untwisted rovings.Ustroystvo 2. Cylinder exhaust vapors 3 rotates in the bath 4 with water.The device operates as follows.Reel 2 captures coming out of the exhaust vapors exhaust device 1 Micco and curls her, then she goes to the prom pair 3, the cylinder which rotates in a bath 4 with water. Sliver moistened with water, picked up by the cylinder exhaust pair 3, and then formed roving roving wound on the spool 5.When these conditions are sliver, captured by the reel, not shoves that increases the quality of the rovings and helps reduce nerovnosti yarn and improving its quality. The forming device untwisted rovings from flax fibers, containing reel to seal sliver and tub to soak sliver, characterized in that the reel is located between the pair of exhaust and outlet pair to drain Rove and wetting sliver occurs by capturing water from baths cylinder exhaust vapors to dissipate Rove.
FIELD: textile industry, in particular, non-circular weaving equipment, for example, weaving units.
SUBSTANCE: apparatus has shaft disposed between columns and adapted for carrying of rotary lever with rotating pressure roll, and spiral spring. Shaft is immovably fixed between flat columns attached by means of bolt-type protrusions to vertically arranged base. Spiral spring is mounted on shaft and spring ends are fixed on rotary lever and on one of columns. Shaft is made stepped and is equipped with basic end portions terminating in threaded parts. Flat columns have rectangular portions continued with bolt-type protrusions. Column arranged at the side of spring end has cylindrical opening for accommodation of rectilinear end of spring. Cylindrical recess provided in rotary lever hub aperture on its internal surface at the side of arrangement of spring is adapted for accommodation of rectilinear end of spring.
EFFECT: improved operating characteristics and operating conditions.
