Description
Technical field
The present invention relates to a kind of weft yarn needle block group for the multiple-axial warp knitting machine for being suitable to production unidirectional cloth.
Background technology
Reinforcing fiber unidirectional cloth, such as carbon fiber unidirectional cloth are widely used in the industry due to superior performance, are especially existed
Using many in wind-powered electricity generation power generation blade.Unidirectional cloth can be knitted using multiple-axial warp knitting machine or biaxial warp knitting machine in theory
Make.If produced with common biaxial warp knitting machine, but the transfer rate of biaxial warp knitting machine cutting and weft yarn needle block differs
Cause, selvedge stress is larger after dicing, produce corrugated side, be commonly called as stringy selvedge, influence the quality of unidirectional cloth, therefore common
Biaxial warp knitting machine is only suitable for doing the unidirectional cloth of small breadth, or improve biaxial warp knitting machine, but biaxial warp knitting machine is in itself
Characteristic, it is very big to improve cost, can cause very big waste.Do not stressed with multiple-axial warp knitting machine in cutting area selvedge, therefore
Be not in stringy selvedge, it is contemplated that cost and the complexity of paving latitude, were all that latitude is spread with rove in the past, and spread latitude process
It is：Weft laying trolley is suspended in the air, and weft yarn, which is hung, enters weft laying device, and weft laying device is moved left and right, and yarn is hung on weft yarn needle, and one
As weft yarn needle and sley point do not change, needle gage when making different fabrics in adjustment weft laying device, therefore weft laying device and weft yarn
The needle gage of pin can be inconsistent, it may appear that uneven hand pick phenomenon, if yarn is rove, the spacing of weft yarn can become very suddenly
Greatly, it is impossible to meet the product quality requirement increasingly improved.Current solution is to change spun yarn paving, accordingly even when hand pick, spacing
Also will not be very big, it is little to the image of product quality.But spun yarn cost can be greatly increased, and easily hold, product quality meeting
Reduction, and production efficiency is relatively low.Especially, as wind power generation blade is increasing, to the quality requirements of fabric just increasingly
Height, as long as there is the phenomenon of yarn skewness, fabric face will out-of-flatness.
The content of the invention
It is an object of the invention to provide a kind of weft yarn needle block group for the multiple-axial warp knitting machine for being suitable to production unidirectional cloth.
The technical scheme for realizing the object of the invention is a kind of weft yarn needle block for the multiple-axial warp knitting machine for being suitable to production unidirectional cloth
Group, weft yarn needle block group includes being respectively provided with X root pins on consistent standard type pin block, A type pin blocks and the Type B pin block of width, three kinds of pin blocks；
On the standard type pin block with the center line of pin block toward the both sides a diameter of Dmm of disposed at equal distance X roots pin；X on the A types pin block
The set location of root pin is that based on standard type pin block, every pin moves backward the diameter of a pin according to yarn direction of travel
Dmm；The set location of X root pins is that based on standard type pin block, every pin is moved according to yarn direction of travel on the Type B pin block
Move the diameter Dmm of a pin；Standard type pin block and A the type pin block and standard type pin block and Type B pin block are separately positioned on paving
The both sides in latitude area；The standard type pin block and Type B pin root tuber are arranged at intervals according to paving latitude breadth；Standard type pin block and A the type pin
Block is rotated after 180 ° according to paving latitude breadth interval setting；Same pin block is set in each paving weft width.
The width of three kinds of pin blocks is Wmm, a diameter of Dmm of X roots pin is respectively provided with thereon, W/X is finite decimal
D ＜ (W-4W/X)/2.
The distance between the standard type pin block, A type pin blocks and adjacent two pins of three kinds of pin blocks of Type B pin block are Ymm, Y
=W/X.
The width of the standard type pin block, A type pin blocks and Type B pin three kinds of pin blocks of block is 25.4mm, and 5 are respectively provided with thereon directly
Footpath identical pin；The distance between adjacent two pins are 5.08mm.
Above-mentioned technical proposal is employed, the present invention has following beneficial effect：(1) present invention is provided with by three kinds of differences
Pin block composition weft yarn needle block group, according to the present invention structure setting weft yarn needle block, weft yarn dolly spread latitude when, paving latitude
Weft yarn is passed in and out under the width of breadth, can just ensure that weft yarn, according to equidistant 90 ° layings, therefore ensures that the product of unidirectional cloth
Matter.
(2) weft yarn needle block of the invention is respectively provided with a conveyor, therefore can be moved in Pu Wei areas, is easy to life
Production.
(3) weft yarn needle block of the invention can be combined into various breadth, very convenient.
