The working mechanism of the present invention is described below:
1, set with the straight line at the center of described location-plate the first installing hole and the place, center of the second installing hole as reference line, and using include this reference line vertical plane as the plane of reference.The described hand-held turning end of handle is using the position that is positioned on this plane of reference as the starting point rotated.In starting point, in described core bar, hypomere central axis and vertical curve have an included angle B, certainly, leave this starting point, and this corner dimension is constant.When operation handle makes core bar rotational angle be ω, and now, in core bar, the described included angle B of hypomere central axis and vertical curve is at projected angle B '=B × COS ω of the plane of reference.When ω is 0 °, projected angle B '=B；When ω=± 90 ° time, projected angle B '=0；When ω=180 °, projected angle B '=-B.Visible, turning handle, projected angle B ' changes at B and-B.Setting B as 6 °, turning handle, projected angle B ' changes between-6 ° and 6 °.Projected angle B ' becomes, and in described core bar, hypomere central axis just becomes with the relative position between Yarn feeding wheel, therefore dividing sinker sleeve also just becomes with the relative position between Yarn feeding wheel.Here it is by rotating described core bar regulation dividing sinker sleeve position relative with between Yarn feeding wheel working mechanism.The original position rotated for handle with the described plane of reference, rotational angle increase, projected angle B ' diminishes, dividing sinker sleeve closer to Yarn feeding wheel tilt, yarn winding spacing on Yarn feeding wheel diminishes, suitable fine yarn close around.When projected angle B ' is big, yarn winding spacing on Yarn feeding wheel becomes big, suitable textured yarn dredge around.So produce dividing sinker effect.
2, in handle rotation process, in core bar, hypomere central axis and the position of Yarn feeding wheel central axis are constantly in change, only when ω is 0 ° and 180 °, in core bar, hypomere central axis is with Yarn feeding wheel central axis just in same perpendicular, and the two position is unfavorable for the walking of yarn.Due to turning handle, in core bar, hypomere central axis is walked (twice that the drift angle of the circular cone of this taper seat is described included angle B) on a taper seat, and avoids vertical plane.So, in core bar, hypomere central axis not only tilts (setting the direction as left and right directions) to the central axial direction of Yarn feeding wheel, tilts the most in front-rear direction.Because at dividing sinker sleeve away from the side of Yarn feeding wheel central axis, the cabling of yarn is fore-and-aft direction, in core bar, hypomere central axis tilts in front-rear direction, dividing sinker sleeve is made to tilt in front-rear direction, just take advantage of a situation direction before and after away from the central axis side yarn cabling of Yarn feeding wheel, beneficially yarn walking.
Compared with the existing technology, it has the beneficial effects that the present invention:
One, by turning handle and core bar, in regulation core bar, the angle of hypomere central axis and vertical curve is at the projected angle of the plane of reference, thus regulating the relative position of hypomere central axis in core bar (i.e. dividing sinker sleeve position) and Yarn feeding wheel central axis, it is achieved the yarn being wound around on Yarn feeding wheel is arranged by its thickness density.It can be said that the present invention is a new generation's dividing sinker yarn-feeding device.
Its two, by turning handle and core bar, in core bar hypomere central axis not only to the central axial direction of Yarn feeding wheel tilt (setting the direction as left and right directions), tilt the most in front-rear direction.In core bar, hypomere central axis tilts in front-rear direction, dividing sinker sleeve is made to tilt in front-rear direction, just take advantage of a situation direction before and after away from the central axis side yarn cabling of Yarn feeding wheel, it is beneficial to yarn walking, fundamentally avoid to cause and twine the induced factor that the yarn downslide being located on Yarn feeding wheel is caving, avoid yarn on Yarn feeding wheel to glide and be caving phenomenon, it is ensured that on Yarn feeding wheel, yarn twines in order and sets 12～16 circles and will not skid.
Its three, can realize without rankization regulation Yarn feeding wheel on be wound around yarn by its thickness density arrange.Prior art due to modulated mode and the restriction of adjustment structure, can only by thin, in, thick big gear is adjusted.The development of weaving goods hommization increasingly, send yarn-feeding device yarn to require all the more and improves, more precision.This thin, in, thick big gear regulation do not adapt to being continually changing of cloth characteristic.As long as the present invention indicate in handle chassis a lower angle (or thin, in, thick shelves), can further fine tuning between each gear, it is achieved without rank regulation.Even can be by handle configurations motor, it is achieved automatic-control stepless does not regulate.It is beneficial to improve production stability, promotes that weaving goods quality improves.
Its four, solve prior art twine the yarn being located on Yarn feeding wheel big with yarn conveying wheel surface frictional force problem.Due to the outer sheathed dividing sinker sleeve of core bar, and equipped bearing, dividing sinker sleeve is equipped with core bar by bearing, dividing sinker sleeve can be with core bar for axle flexible rotating, and yarn need not stretch tight the tightest between Yarn feeding wheel and dividing sinker sleeve, and yarn is walked freely at dividing sinker sleeve and yarn conveying wheel surface, dividing sinker sleeve and Yarn feeding wheel are the least to the kinetic force of friction of yarn, the damage causing yam surface to be subject to reduces, and especially smoothness and glossiness is not damaged, and is beneficial to improve the quality of woven product.
Its five, the angle of the length direction of the straight line at the center of the first installing hole and the place, center of the second installing hole and frame horizontal stroke seat is the acute angle of 45～60 degree, causes the position that arranges of core bar and dividing sinker sleeve to be positioned at the rear ramp of Yarn feeding wheel.Compared with existing yarn-feeding device, therefore the space needed for circular disc knitting machine board is installed can be reduced, on Yarn feeding wheel during winding yarn, can be more convenient.
They are six years old, owing to the position that arranges of core bar and dividing sinker sleeve is positioned at the rear ramp of Yarn feeding wheel, when circular disc knitting machine works, no matter rotate clockwise or counterclockwise, yarn all can make its yarn arrays stable via the lead-in chamfered on Yarn feeding wheel before dividing sinker sleeve, will not move up and down, to ensure the quality of cloth product.And existing Yarn feeding wheel must divide rotation direction clockwise and anticlockwise, to determine that core bar and dividing sinker sleeve are placed on left side or the right side of Yarn feeding wheel.
Its seven, simple in construction and ingenious.Relative to the technical scheme of " adjustable yarn-feeding device " (Authorization Notice No. CN202594515U), the dividing sinker structure of the present invention is simply too much, and regulation operation is also convenient for.This is conducive to manufacturing, and fault is few, produces more stable, and service life is the longest, simultaneously facilitates maintenance.
