Description
Technical field
The invention belongs to field of textile machinery, it is related to a kind of symmetrical warp let-off method and device of single needle bar warp knitting machine, especially relates 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 technology
One group or several groups of yarns arranged in parallel, in warp-wise feed machine all working pin on, while lopping and formed
Knitted fabric, this method is referred to as warp knit, and fabric is referred to as knitted fabric, completes this warp-knit machine and is referred to 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-bar number, and traditional single needle bar warp knitting machine will be sent
The preceding side of machine is all arranged at through system, because yarn is more, yarn especially grey is difficult to the very fine wires yarn differentiated
Breakage phenomena is difficult to be found, even if yam breakage phenomena is found, the yarn of fracture is looked for from the warp of substantial amounts
Go out it is also extremely difficult, particularly in the middle of sley bar yarn broken yarn when, be more difficult to find, it is often necessary to shut down and need spend compared with
It can just find, be perplexed by the more yarn in side, broken yarn joint is also relatively difficult for a long time, for traditional single needle bed warp knit
Machine, it is many that sley bar can only be entried respectively successively when warp thread is entried, reduce speed of entrying, low production efficiency, when quantity is 2
It is every that the angle for sending yarn route and center crossbeam of sley bar is differed when sley bar more than carries out the warp let-off, asymmetric send is presented
Through route, therefore every warp let-off tension force in sley bar is differed, and every synchronism that sley bar is fluctuated within the lopping cycle is differed,
The knot for the fabric being especially formed by weaving finally for fabric by the yarn of the low elongation high-modulus such as glass, wire, carbon fibre
The influence of structure loop 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, be not suitable for the single needle bed warp let-off, send yarn path longer, warp let-off surrounded by angle is excessive, low production efficiency.
Patent CN201510865752.9 discloses a kind of single needle bar warp knitting machine, including looping device, guide bar assembly, transmission
Device etc., looping device includes needle-bar part, nook closing member bed part, knocking over bed part, sinker bed part, 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 pressure yarn part, transmission device includes needle-bar
Transmission mechanism, nook closing member transmission mechanism, knocking over transmission mechanism, pressure yarn transmission mechanism, needle-bar transmission mechanism provide dynamic to needle-bar part
Power, nook closing member transmission mechanism provides power to nook closing member bed part, and knocking over transmission mechanism provides power to knocking over part, presses yarn driver
Structure provides power to pressure yarn part and controls it to move, and invention uses connecting rod or cam drive, and machine run is steady, noise is low,
Rotating speed is high, improves production efficiency, makes flower pattern more rich in third dimension, when being spinned for the yarn of low elongation high-modulus,
Breakage phenomena is still more serious.
Therefore, research one kind can quickly entry, reduce yam breakage phenomena, improve fabric quality and the list of production efficiency
The warp let-off method and device of needle-bar tricot machine has important practical significance.
