Description
Technical field
The invention belongs to field of textile machinery, are related to a kind of symmetrical warp let-off method and device of single needle bar warp knitting machine, especially relate to
And a kind of yarn by low elongation high-modulus is transported to the symmetrical warp let-off method of the single needle bar warp knitting machine of looping mechanism from coiled hair
And device.
Background technique
One group or several groups of yarns arranged in parallel, in through to feeding machine all working needle on, while lopping and formed
Knitted fabric, this method are known as warp knit, and fabric is known as knitted fabric, complete this warp-knit machine and are known as tricot machine, tricot machine
It is widely used in field of textiles.
Tricot machine can be divided into single needle bar warp knitting machine and double rib warp loom by needle bed number, and traditional single needle bar warp knitting machine will be sent
The preceding side of machine is all set to through system, since yarn is more, yarn especially grey is difficult to the very fine wires yarn differentiated
Breakage phenomena is not easy to be found, even if yam breakage phenomena is found, the yarn of fracture is looked for from the warp of substantial amounts
Also extremely difficult out, especially intermediate sley bar yarn broken yarn when, be more difficult to find, it is often necessary to shut down and need to spend compared with
It can just find for a long time, by the puzzlement of the more yarn in side, broken yarn connector is also relatively difficult, for traditional single needle bed warp knit
Machine, it is more that sley bar can only successively be entried respectively when warp thread is entried, speed of entrying is reduced, production efficiency is low, when quantity is 2
When above sley bar is carried out the warp let-off, every angle for sending yarn route and center crossbeam sley bar is not identical, and asymmetric send is presented
Through route, thus it is every that warp let-off tension in sley bar is not identical, and every synchronism that sley bar is fluctuated within the lopping period is not identical,
Finally for the knot for the fabric that fabric is especially formed by weaving by the yarn of the low elongations high-modulus such as glass, wire, carbon fiber
The influence of structure coil length and Tension Evenness is more serious.
Patent CN20091002818.4 discloses a kind of let-off motion, but this let-off motion is used in two-needle bar warp knit
On machine, is not suitable for the warp let-off of single needle bed, send yarn path longer, warp let-off predetermined curvature is excessive, and production efficiency is low.
Patent CN201510865752.9 discloses a kind of single needle bar warp knitting machine, including looping device, guide bar assembly, transmission
Device etc., looping device include needle bed part, needle core bed portions point, knocking over bed portions point, sinker bed portions point, and guide bar assembly includes fan
Shape plate, fan-shaped panel seat, upper balance staff, at least one ground is combed, at least one jacquard comb and presses yarn part, transmission device includes needle bed
Transmission mechanism, needle core transmission mechanism, knocking over transmission mechanism, pressure yarn transmission mechanism, needle bed transmission mechanism provide needle bed part dynamic
Power, needle core transmission mechanism provide power to needle core bed portions point, and knocking over transmission mechanism provides power to knocking over part, press yarn driver
Structure provides power to pressure yarn part and controls its movement, and invention uses connecting rod or cam drive, and machine run is steady, low noise,
Revolving speed is high, improves production efficiency, makes flower pattern more rich in three-dimensional sense, when spinning for the yarn of low elongation high-modulus,
Breakage phenomena is still more serious.
Therefore, studying one kind can quickly entry, reduce yam breakage phenomena, improve the list of fabric quality and production efficiency
The warp let-off method and device of needle bed tricot machine has important practical significance.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of yarns that can be realized low elongation high-modulus quickly to wear
Yarn, while reducing the symmetrical warp let-off method and device of the single needle bar warp knitting machine of its breakage phenomena.
