Abstract
The invention provides an inward rotating type weft accumulator. The inward rotating type weft accumulator comprises a yarn storage barrel, a pay-off spool driven by a driver to rotate is arranged on the end edge of one end of the yarn storage barrel and comprises a pay-off hole in the inner side of the yarn storage barrel, a weft release ring capable of allowing weft to pass is arranged in the center of the other end of the yarn storage barrel, a ventilating conveying belt carrying out conveying in the axial direction is annularly arranged on the inner wall of the yarn storage barrel, the ventilating conveying belt is driven by drilling guide rolls at the two ends of the yarn storage barrel, the corresponding inner wall, with the ventilating conveying belt, of the yarn storage barrel is of a net-shaped ventilating structure, and air passes through the ventilating conveying belt and the net-shaped ventilating structure through a ventilating component from inside to outside. Weft is spirally distributed to the ventilating conveying belt through the pay-off spool, when the weft release ring releases the weft, the weft is pulled away from the ventilating conveying belt at first time, the weft moves in air in the whole motion, and therefore friction force and vibration borne by the weft are small.
Description
Art
The present invention relates to loom auxiliary equipment field, especially, is a kind of inner-rotary type weft accumulator for shuttleless loom.
Background technology
In weaving process, the constant of strict control weft tension is vital for raising fabric quality.Along with developing rapidly of edge-less loom and improving constantly of filling insertion rate, more outstanding to the control problem of weft tension, the use of weft accumulator has just been arisen at the historic moment.If weft yarn is directly drawn from bobbin during wefting insertion, because wefting insertion process accounts for 120 degree to about the 180 degree times of one turn, main shaft, now the withdrawal speed of weft yarn is equivalent to 2 to 3 times into latitude rate, and wefting insertion is again interval generation, the weft unwinding be interrupted and cause weft tension to have larger fluctuation along with the continuous minimizing of bobbin unwinding radius, causes weft breakage and the various float caused by wefting insertion constantly to increase.Employ weft accumulator, weft yarn, after unwinding bobbin, is first winding on weft accumulator and stores, and then by wefting insertion, weft yarn is got off to introduce rib mouth from unwinding weft accumulator.If regulate weft accumulator speed rightly, the unwind process nearly continuity that yarn is conformed to the principle of simplicity on son can be made to carry out, and withdrawal speed is close to entering latitude rate. thus make the Weft Insertion of unwinding tension and weft yarn more even.
Traditional weft accumulator adopts the winding method the same with yarn cylinder, the weft yarn of unwinding end be also around weft accumulator around the unwinding of yarn drum, this kind of Withdrawing Mode makes around constantly rotating around yarn drum due to the unwinding point of weft yarn, therefore the tension force of weft yarn is also fluctuation, and weft yarn and the friction around yarn drum, too increase unwinding resistance.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of inner-rotary type weft accumulator, the weft unwinding vibrations on this inner-rotary type weft accumulator are little, tension fluctuation is little.
The technical solution adopted for the present invention to solve the technical problems is:
This inner-rotary type weft accumulator comprises yarn storage cylinder, one end end of described yarn storage cylinder along on the draw drum that a driver drives rotates is set, described draw drum comprises the unwrapping wire hole be arranged on inside yarn storage cylinder, what the other end center of described yarn storage cylinder was provided with weft yarn puts yarn ring, described yarn storage cylinder inwall is equipped with the ventilative conveyer belt transmitted vertically, described ventilative conveyer belt is driven by the driving deflector roll being arranged on yarn storage cylinder two ends, it is Reticular breathable structure that described yarn storage cylinder arranges inwall corresponding to ventilative conveyer belt, described ventilative conveyer belt and described Reticular breathable structure pass through air from inside to outside by vent members.
As preferably, be positioned at described yarn storage cylinder and synchronously drive described ventilative conveyer belt with the driving deflector roll of one end by the mode of adjacent series connection universal joint.
As preferably, described ventilative conveyer belt sprays point-like colloid by elastomeric fabric surfaces and forms.
As preferably, described vent members comprises the air-supply arrangement being arranged on described yarn storage cylinder one end, and the end cover being arranged on yarn storage cylinder two ends coordinates and forms, described in put yarn ring and be arranged on the end cover center of described yarn storage cylinder with end.
The invention has the advantages that:
The rotation of described draw drum, weft yarn is distributed in the loop configuration of described ventilative conveyer belt composition, described weft yarn is constantly moved to putting yarn ring by described ventilative conveyer belt, weft yarn is subject to the air effect through described ventilative conveyer belt, and be attached on described ventilative conveyer belt, when described put yarn ring release weft yarn time, weft yarn is detached described ventilative conveyer belt by the very first time, whole motion weft yarn moves all in atmosphere, therefore the frictional force that is subject to of weft yarn is very little, and be the axis radial motion along described yarn storage cylinder by the weft yarn putting the release of yarn ring, therefore vibration amplitude is also little.
