Description
Technical field
It the utility model is related 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, especially existed due to superior performance in the industry
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
Causing, selvedge stress is larger after dicing, produces corrugated side, is commonly called as stringy selvedge, influences 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, improve get up cost it is very big, very big waste can be caused.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 to spread latitude with rove in the past, and spread latitude process
It is：Weft laying trolley is suspended in the air, and weft yarn is hung into weft laying device, weft laying device and moved left and right, and yarn is hung on weft yarn needle, and one
As weft yarn needle and sley point do not change, the needle gage in weft laying device, therefore weft laying device and weft yarn are adjusted when making different fabrics
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 greatly increase, and easily hold, product quality meeting
Reduce, 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.
