Description
Technical field
The present invention relates to a kind of weaving device more particularly to a kind of bifilar doubling devices.
Background technique
Many advantages, such as taper cylinder yarn has easy unwinding, is not easy off-clip, in entire spinning technological process, taper cylinder yarn
It is indispensable yarn organizational form, due to the needs of next procedure, many processes often require that production taper cylinder yarn.
Doubling frame can usually merge two strands of single thread to form one folded yarn (non-twist plying), and when plying is usually most important
The problem of be control two one threads plying when keep identical tension, such two strands of single thread are not in length when forming one
Line problem, if there is long short-line problem, double twisting stage of the folded yarn in lower road is easy broken yarn, also easily occurs in and twists thread above to go out
Existing " small tail ", it is therefore desirable to which the unwinding tension of two yarns of strict control guarantees that two strands of single thread keep length one in plying
It causes.
Further, doubling is problem is encountered that two cylinder yarns are unwound at the same time when combining, since what two cylinder yarns were wrapped remains
Remaining amount of thread is not necessarily identical, and especially remaining seldom (yarn wound packages diameter is smaller) in a cylinder yarn, another cylinder yarn is remaining
Very much (yarn wound packages is relatively large in diameter) equally unwinds one meter of yarn, the circle number that the lesser cylinder yarn of yarn wound packages diameter needs to unwind
The cylinder yarn being relatively large in diameter far more than yarn wound packages, further, in yarn unit unwound length, the circle number of unwinding is more, online
Unwinding tension is bigger.Therefore when cylinder yarn doubling not of uniform size, since cylinder yarn factor of different sizes causes and line mass
Problem needs to eliminate.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provide a kind of simply bifilar doubling device of structure.
In order to achieve the above objectives, the technical solution adopted by the present invention are as follows: a kind of bifilar doubling device, including and set two
Yarn road, the road Liang Tiaosha the yarn respectively unwound out is pooled together after in the same cylinder yarn, every road Tiao Sha includes:
The floating drum of bottom setting driving means and the creel being arranged near floating drum, which is characterized in that the floating drum further includes being arranged
Upper cap and lower cap together are provided with floating spring, the driving means in the chamber that the upper cap and lower cap are collectively formed
The push rod being arranged on the lower cap bottom, the driving means is arranged to protrude into the lower cap and resist the floating spring, institute
It states crown portion and is provided with the indent passed through for yarn, the indent two sides are also each provided with a yarn guiding wheel, on the lower cap
Gas circuit is connected, the indent bottom is provided with several air gaps arranged along thread path, is provided with gravity on the creel

In a preferred embodiment of the present invention, the push rod is by motor and threadingly hole rotation.
In a preferred embodiment of the present invention, the floating drum two sides are symmetrically arranged in two yarn guiding wheels.
In a preferred embodiment of the present invention, the floating drum axially movable when, keep yarn led in yarn guiding wheel-air gap-
At broken line or linear state on the thread path of yarn wheel, and the yarn presses above air gap always.
In a preferred embodiment of the present invention, the gravity sensor detects cylinder yarn weight, and cylinder yarn weight data is passed
Defeated to arrive driving means, the driving means is according to the height of cylinder yarn adjustment of weight push rod.
In a preferred embodiment of the present invention, the floating spring top and bottom be respectively held against crown portion inner wall and
The top of push rod.
In a preferred embodiment of the present invention, top plate, the top plate and the lower cap inner circumferential are provided at the top of the push rod
Structure is coincide.
In a preferred embodiment of the present invention, wedge-shaped stomata, the wedge shape stomata osculum court are additionally provided in the top plate
On, big mouth down, the big mouth is sealed by net, and sprue is arranged in the wedge shape stomata.
The invention solves the defect existing in the background technology, the present invention have it is following the utility model has the advantages that
(1) structure being mutually buckled together using upper cap and lower cap can form the quasi- elastomer that can be floated up and down,
With the continuous progress that the same cylinder yarn is unwound, thickness of the yarn on bobbin is smaller and smaller, and the air pressure being filled in floating drum is bigger,
Upper cap height is higher, and compensation is bigger to the tension of yarn, i.e., cylinder yarn is lighter, and air pressure is bigger, and compensated unwinding tension is bigger；Cylinder
Yarn is heavier, and air pressure is smaller, and compensated unwinding tension is smaller, it can guarantees to be much regardless of the weight of cylinder yarn, be always ensured that
Certain unwinding tension is compensated, two stock yarn lines is made finally to have identical unwinding tension.
(2) cap and lower cap, which are mutually buckled together, on to form floating structure and can buffer Yarn tension fluctuation, and it is big to give tension
The supplement of minor swing further plays damping action.
(3) two cooperate between yarn guiding wheel and indent, and yarn carrying is formed on the distinctive operating path of yarn,
Change the bending degree of thread path by the floating of upper cap, floating drum is more top, and compensation is bigger to the tension of yarn, and floating drum more leans on
Under, the tension to yarn is compensated with regard to smaller, and the position lower limit of upper cap can be two yarn guiding wheels and indent bottom three point on a straight line
When, it compensates at this time almost nil to the tension of yarn.
(4) indent forms hump structure, by the way that yarn setting in peak valley bottom, is guaranteed that yarn will not flee easily.
(5) the dynamic changes factors such as tension-cylinder yarn weight when cap height-unwinding yarn is gone up in the position-of push rod form dynamic
State closed loop logic structure forms automatic unwinding constant tension system by above-mentioned logical construction.
(6) by the function of gravity sensor, the dynamic monitoring of cylinder yarn gravity is realized, and then demand pusher is in lower cap
Position, to form the effect that dynamic adjusts tension.
(7) provide dynamic equilibrium air pressure by gas circuit for floating drum inner cavity, air gap setting in indent bottom, can yarn with
The position of floating drum mere contact provides the outer air-flow sprayed, makes to press and is slightly formed the suspension that air-flow is blown in the yarn of indent bottom
State reduces sliding friction, and then reduces the frictionally damage of yarn.
(8) when push rod quickly adjusts position, sprue can be formed does not influence the deflation of floating drum inner cavity upwards for wedge shape starting, but
Floating drum inner cavity air-breathing speed can be slowed down.When increasing supplement tension, feedback speed is very fast, and when reduction compensation tension, feedback
Speed is slower.
