The course of work of feed carrier is as follows:
Yarn 10 is sent out from yarn jaw 6 in spinning process, and by the yarn guiding trough 53 on feed carrier, yarn 10 divides at this time
It is not contacted with two lug bosses on revolving part 5, subsequent yarn 10 is finally wound up on spindle by twizzle 7 and wire loop.
In spinning process, yarn 10 is contacted with two lug bosses always, and by the effect of its power, while revolving part 5 is defeated in yarn 10
It applies during sending and is rotated under the drive of frictional force.
The working principle that this spinning apparatus can reduce filoplume is as follows:
Ring throstle spinning process Yarn twisting principle and filoplume Producing reason are introduced first.In general, traditional
The formation of ring spinning yarn filoplume is mainly due to after the draft area of spun yarn applies certain drawing-off to rove, in order to make yarn
Intensity needed for obtaining must be plus certain twist to fetter fiber.Turn in yarn be from wire loop generate the twist to
On be transmitted to drafting system.The twist must be close to the jaw line of roller, but it but can not be completely into jaw.?
At the output of front roller, it is constantly present the triangular fibre beam of a not no twist, i.e., so-called twist triangle zone.Twist triangle
Shape, the size in area suffer from conclusive effect to the structure of resultant yarn, runnability (broken end), strength and surface characteristics etc..
The fiber of twist triangle zone is in because being produced radial pressure or radial pressure by the effect of spinning tension and twisting.In twisting three
The fiber radial pressure of angular region edge is maximum, and in the fiber of yarn axis center, radial pressure is minimum.Due to ectonexine fiber stress
The both ends for shifting fiber repeatedly of fiber from inside to outside and from outside to inside will occur in twist triangle zone and also often expose for difference
Form Yarn filoplume outside.
Based on the above spinning process, the working principle that a kind of feed carrier of the invention reduces Yarn filoplume is as follows:
By two lug bosses on revolving part 5, yarn two sides are applied between twizzle and yarn jaw opposite
Power, power generate component in yarn centripetal direction, as shown in figure 8, the filoplume to outer layer fiber applies centripetal force, while yarn exists
Continue to twist under wire loop turning effort, filoplume is just twisted into again as inner fiber, and then reduces filoplume.
Also, 51 surface hardness of lug boss when revolving part 5 is installed far from 6 one end of yarn jaw is less than other end lug boss
52 surface hardnesses, the big lug boss surface shore hardness of hardness are 70 to 85, and the small lug boss surface shore hardness of hardness is 62
To 77.The yarn 10 big lug boss of contact surface hardness, frictional force first is small, it is easier to slide into yarn guiding trough, then and the other end
The lesser lug boss contact of surface hardness, frictional force is bigger, increases the active force to yarn.
Revolving part 5 can be manufactured with two kinds of materials, be molded and formed in the connecting shaft 56 of two lug bosses, and lug boss can be used
Metal material can be used in polyurethane material, connecting shaft 56.In this way mainly due to the material of two kinds of different surfaces hardness
Material is not easy one-pass molding, can facilitate manufacture using the method.
Revolving part is axial when revolving part 5 is installed spends with horizontal sextant angle for 35 to 55, this angle is operating angle.
Further, shock absorber part 2 selects vibration-absorptive material, such as silicon rubber.Since in spinning process, yarn is certain to generate
It swings, when passing through this feed carrier, damping device can absorb the vibration passed to from revolving part 5, avoid yarn and rotation
5 rigid contact of part reduces broken yarn rate.
Locating piece 8 is caught in the groove 54 of revolving part 5 for limiting 5 excessive slew of revolving part.Locating piece 8 and revolving part 5 one
It rises and seals bearing 4, prevent flyings from influencing bearing working.Defined above, positioning and sealing function guarantee the normal work of feed carrier
