Abstract
The present invention provides a kind of swing weft accumulator, including the unwrapping wire head of output weft yarn downwards, the unwrapping wire head is arranged on a wobble channel and moves back and forth, yarn guiding wheel pair is provided with immediately below the unwrapping wire head, unwrapping wire head tremor of the present invention constantly releases weft yarn while pendulum, the weft yarn in the yarn storage cover constantly declines and expands with gravity because waving, and thus weft yarn is by corrugated storage, resistance during effective weft unwinding.
Description
Technical field
The present invention relates to auxiliary equipment field of weaving, especially, is that swing weft accumulator is used in a kind of weaving.
Background technology
In weaving process strict control weft tension it is constant for improving fabric quality it is critical that.With nothing
Rib loom develop rapidly and filling insertion rate continuous improvement, the control problem of weft tension more projected, weft accumulator makes
With just arising at the historic moment.If weft yarn is directly led out from bobbin during wefting insertion, as wefting insertion process accounts for 120 degree of one turn of main shaft
To 180 degree or so the time, now the withdrawal speed of weft yarn is equivalent to entering 2 to 3 times of latitude rate, and wefting insertion is that interval occurs again,
Disconnected weft unwinding and with bobbin unwind radius continuous reduction cause weft tension to have larger fluctuation, cause weft yarn break
Head and the various float caused by wefting insertion are continuously increased.After having used weft accumulator, weft yarn to unwind from bobbin, it is winding to first
Store on weft accumulator, then weft yarn is unwind from weft accumulator by wefting insertion and introduce rib mouth.
Traditional weft accumulator stores weft yarn typically using metal creel, therefore, weft yarn also has one after unwinding from creel
Fixed resistance, is not suitable for loom and further improves speed.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of swing weft accumulator, the swing weft accumulator
The resistance of weft unwinding is less.
The technical solution adopted for the present invention to solve the technical problems is：
The swing weft accumulator includes the unwrapping wire head for exporting downwards weft yarn, and the unwrapping wire head is arranged on past on a wobble channel
It is multiple to move, yarn guiding wheel pair is provided with immediately below the unwrapping wire head.
Preferably, the yarn storage cover for accommodating weft yarn is provided between the unwrapping wire head and the yarn guiding wheel pair.
Preferably, the yarn storage cover is incremented by along the width that unwrapping wire head tremor puts direction downwards.
Preferably, the upper end of the yarn storage cover arranges the air-blast device of oriented yarn storage cover lower end air-blowing.
Preferably, the downward passage in direction is provided with the yarn storage cover inwall, spray in the passage, is provided with
Valve.
Preferably, the yarn storage cover is provided with conductive layer, both sides along the both sides inwall of unwrapping wire head vibration-direction
Described conductive layer is connected with the two poles of the earth of an electrostatic generator.
It is an advantage of the current invention that：
The unwrapping wire head tremor constantly releases weft yarn while pendulum, the weft yarn because wave with gravity in the yarn storage cover not
Disconnected to decline and expand, thus weft yarn is by corrugated storage, resistance during effective weft unwinding.
Description of the drawings
Fig. 1 is that this swing weft accumulator faces tangent plane structural representation.
Fig. 2 is the A-A structural representations of this swing weft accumulator Fig. 1 embodiment.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
In the present embodiment, refering to Fig. 1 and Fig. 2, the swing weft accumulator includes the unwrapping wire head for exporting downwards weft yarn 10
200, the unwrapping wire head 200 is arranged on a wobble channel and moves back and forth, and the underface of the unwrapping wire head 200 is provided with yarn guiding wheel
To 500.
Above-mentioned swing weft accumulator, the unwrapping wire head 200 and the yarn guiding wheel accommodate weft yarn to being provided between 500
Yarn storage cover 100, the width that the yarn storage cover 100 waves direction along unwrapping wire head 200 are incremented by downwards, to adapt to weft yarn 10 by unwrapping wire head
Constantly decline after 200 releasings and produce expansion.
Refering to Fig. 2, the yarn storage cover 100 is by two pieces of narrow sides being oppositely arranged, 110,120 and two pieces of 130 structures of wide side plate
Into.
Above-mentioned swing weft accumulator, the upper end of the yarn storage cover 100 arrange the air blast of oriented 100 lower end air-blowing of yarn storage cover
Device 300, the air-blast device 300 are ventilated to yarn storage cover 100 by the gas-permeable nets of 100 upper end of yarn storage cover, the air-blast device
300 speed that can control the decline of weft yarn 10, to control the density of yarn storage.
Above-mentioned swing weft accumulator, is provided with the downward passage 140 in direction on 100 inwall of yarn storage cover, described
Air nozzle 400 is provided with passage, downward gas is formed by inner surface of the passage 140 in the yarn storage cover 100
Fluid layer, prevents weft yarn 10 from producing friction with yarn storage cover 100, while the air-flow of the injection of passage 140 can supplement air-blast device 300
The throughput that downward air-flow lacks because of 100 width expansion of yarn storage cover.
Above-mentioned swing weft accumulator, both sides inwall 110,120 of the yarn storage cover 100 along unwrapping wire head vibration-direction
On be provided with conductive layer, the conductive layer described in both sides is connected with the two poles of the earth of an electrostatic generator, is declining the weft yarn 10
Cheng Zhong, the electric charge inside weft yarn 10 make the both sides bending point of weft yarn 10 because electric field force is to the direction movement for pointing to both sides conductive layer
Conductive layer is close respectively, makes the fluctuating margin of weft yarn 10 wider.
The operation logic of above-mentioned swing weft accumulator：
Refering to Fig. 1, weft yarn 10 while the unwrapping wire head 200 is waved, is constantly released, the weft yarn 10 is because waving and gravity
In the yarn storage cover 100 constantly decline and expand, by the size for controlling the downward air-flow of air-blast device 300, can control
Density (i.e. Chu Weiliang) of the weft yarn 10 in yarn storage cover 100, the conductive layer can control the electric charge conductive layer in weft yarn 10
Both sides migrate, and then attract weft yarn 10 to control the Pulse Width of weft yarn 10, and the air-flow of the injection of the passage 140 can prevent latitude
The contact yarn storage of yarn 10 cover 100.
Described is only presently preferred embodiments of the present invention, not to limit the present invention, all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvements made etc. should be included in protection scope of the present invention.
