Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As Figure 1-3, a kind of yarn bobbin winding coiling and molding device, comprises the guide wire 1 be successively set in frame, lower porcelain mouth 2, tensioner 3, upper porcelain mouth 4, groove drum 5 and chuck 6.Described frame is provided with base 23 between lower porcelain mouth 2 and tensioner 3, and base 23 upper surface is provided with yarn-feeding device, front thread board 7, Yarn heater 8, rear thread board 9, yarn mechanism successively along yarn working direction.Base 23 is provided with installation through hole, the activity of described Yarn heater 8 wears in through-holes, the position rack that through hole is being installed at base 23 back side is provided with cylinder 10, and Yarn heater 8 is connected to the piston rod end of cylinder 10, and when Yarn heater 8 normally works, cylinder 10 piston rod is in the state of stretching out.Yarn heater 8 is provided with the groove passed for yarn.Heat-insulating shield 11 is covered with outside Yarn heater 8.
Yarn-feeding device comprise rotate be arranged on base 23 for the capstan roll 12 that compresses yarn and the forward pull roller 13 be oppositely arranged with capstan roll 12.Yarn mechanism comprise rotate be arranged on base 23 by deflector roll 14 and with the backward pull roller 15 for compressing yarn be oppositely arranged by deflector roll 14, capstan roll 12 radius is yarn by the 1.05-1.25 of deflector roll 14 radius doubly, and choosing fills suitable capstan roll 12 and by deflector roll 14 as required.The roll shaft of capstan roll 12 is positioned at base 23 back portion to be arranged with active synchronization band 20 and to take turns 16, the part being positioned at base 23 back side by the roll shaft of deflector roll 14 is arranged with passive and synchronous band 20 and takes turns 17, base 23 back side is also provided with tension wheel 18 and idler 19, Timing Belt 20 is walked around active synchronization band 20 successively and is taken turns 16, tension wheel 18, passive and synchronous band 20 takes turns 17 and idler 19, base 23 is provided with the synchronous dynamo 21 driving active synchronization band 20 to take turns 16 rotations, base 23 back side is provided with two spring pressurization devices 22 be respectively used to forward pull roller 13 roll shaft and the pressurization of backward pull roller 15 roll shaft.
Principle of work: yarn capstan roll 12 is driven by synchronous dynamo 21 power and rotates, take turns 16 by active synchronization band 20 simultaneously, Timing Belt 20 drives and passive and synchronously take turns rotation, thus yarn is rotated by deflector roll 14, forward and backward jockey pulley 15 under the effect of spring pressurization device 22, lean against capstan roll 12 respectively and by the roll surface of deflector roll 14, yarn is by capstan roll 12 and be fed forward by the friction force of deflector roll 14.
Yarn capstan roll 12 linear speed is greater than yarn, and by the linear speed of deflector roll 14, (speed ratio is adjustable according to different yarns raw material, general at 5%-25%), make yarn capstan roll 12 and by deflector roll 14 between produce tension-free state, capstan roll 12 and to be heated through Yarn heater 8 by the yarn between deflector roll 14 and produce crimp shrinkage and elasticity.
Usually the shrinkage percentage of this type of yarn is 5%-25%, overfeeding send the speed of yarn to equal the yarn shrinkage set than the ratio of the speed of groove drum 5 winding yarn, after overfeeding wheel send yarn, yarn keeps lax free state, after heating, yarn shrinkage is to the shrinkage percentage of setting, then pressurizeed to yarn by tensioner 3 (tension pulley), give the winding tension that yarn is certain, facilitate yarn groove drum 5 guide shaping.
Because different yarn fibers fusing points is different, Yarn heater 8 requires according to different yarns and different shrinkage percentages the temperature that setting is different.
