Description
Technical field
The utility model relates to a kind of textile machine dedicated devices, relates in particular to the improvement of ring throstle or ring doubling frame spindle structure.
Background technology
Spindle and supporting with it bobbin are the important devices in ring throstle and the ring doubling frame twisting and winding mechanism.The beginning of in the twisting spinning process of yarn, carrying out yarn always spin with full packages after doff.
Existing spindle mainly comprises spindle blade, wharve, bearing and spindle support, and spindle blade can be supported on the spindle support at a high speed through bearing rotatably, on spindle blade, tightly is with wharve regularly.During spinning, on the spindle spindle blade, bobbin is housed, bobbin is along with spindle spindle blade and wharve together rotate so that yarn is twisted, thereby the yarn after the twisting is winding to formation cop on the bobbin; Ring rail came downwards to the position of doffing when cop spun full end, and yarn is pulled up full yarn bobbin and pulls apart or cut off yarn and accomplish full yarn from spindle blade by a few back spindle stalls of top around the spindle wharve in spindle moderating process.When yarn beginning is spun, plug bobbin again, the root of bobbin cover is just at the right time pushed down on the tail yarn on the wharve, and the back ring rail that brings into operation is up, and yarn is again by on new bobbin, the circulation that the spinning beginning is new.Therefore on spindle, staying tail yarn and pincers to hold the tail yarn is the spinning process circulation important step of carrying out continuously, and pincers is held the tail yarn and can effectively be reduced artificial repiece quantity accurately and reliably, and this is to the spinning machinery of the being furnished with integral cosine doffing device particular importance that seems.
But existing this spindle stays tail yarn mode to have tangible deficiency: the one, and pincers is held the residence tail yarn on the ingot position is arranged accurately and reliably in full packages doffs process; Form the too much need ingot position of repiece again; Not only expend more manual work; And prolonged the downtime of spinning, it is more obvious especially when spinning fiber product and low count yarn, to seem; The 2nd, too much or long repiece tail yarn is twined on spindle wharve top; Make bobbin on spindle blade exactly plug-in mounting put in place; Cause easily bobbin beat and rolling is trembled, spinning broken end is increased, influence spinning quality again; Also need manual work to clear up after repeatedly doffing, throwing away of tail yarn also caused increasing of adjacent ingot position broken end simultaneously; The 3rd, too much long repiece tail yarn also is directed at the waste of spinning material, increases the spinning flyings, strengthens maintenance cleaning cost.
The utility model content
To the above-mentioned deficiency of existing in prior technology, the utility model technical problem to be solved provides the reliable pincers of a kind of ability and holds yarn tail and tail yarn and stay the short automatic pincers of ability of tail to hold the spindle of tail yarn.
In order to solve the problems of the technologies described above; The automatic pincers of a kind of ability of the utility model is held the spindle of tail yarn; Comprise spindle blade, and fixing tightly be placed in the wharve on the spindle blade, also fixing tightly being with fixed cover and yarn clipping top cover on said spindle blade; This yarn clipping top cover is positioned at the upper end of fixed cover, and fixed cover is positioned at the top of said wharve; Be set with pincers in the slip of the outside of said fixed cover and hold sliding sleeve, pincers is held between sliding sleeve and the fixed cover spring is housed; Be arranged in the movable steel ball hole on the fixed cover and be equipped with movable steel ball versatilely, the inboard that pincers is held sliding sleeve is provided with Baltimore groove, and the position of this Baltimore groove is corresponding with movable steel ball hole position.
After adopting said structure, hold sliding sleeve, be fixed with the yarn clipping top cover in the upper end of fixed cover owing to be set with pincers in the slip of the outside of fixed cover; Pincers is held between sliding sleeve and the fixed cover spring is housed; And be equipped with movable steel ball on the fixed cover versatilely, when Yarn-spinning spindle in normal spinning process, because spindle and fixed cover thereof are in the high speed rotation status; The movable steel ball that is disposed radially on the fixed cover is outwards dished out under action of centrifugal force; Enter into pincers and hold the inboard Baltimore groove of sliding sleeve, and hold sliding sleeve to the lower compression spring, form the separation slit between the top end face and yarn clipping top cover thereby hold on the sliding sleeve at pincers through this Baltimore groove and pincers; And spindle speed reduces when also braking stall very soon when the full yarn of bobbin need doff; Movable steel ball loses centrifugal action; Pincers is held the down upwards pushing of effect that slides over spring force, makes pincers hold sliding sleeve upper end and yarn clipping top cover lower end closure and pincers is held repiece tail yarn.The direct nip tail yarn tail end of this structure ability has realized that the anury yarn twines on the spindle on the one hand, and the tail yarn stays tail short, has exempted the burden of cleaning tail yarn, has saved spinning material and has maintained the cleaning cost; On the other hand this structure exactly pincers hold the tail yarn, the automatic repiece rate of reliable clamping is high, has significantly reduced artificial repiece workload, more is applicable in collective's automatic doffing spinning machine; Again on the one hand, this structure tail yarn stays tail short, has avoided the influence of tail yarn to adjacent ingot position, has effectively improved yarn qualities, reduces adjacent yarn breakage.
The further embodiment of the utility model, the periphery of said yarn clipping top cover is provided with the Yarn cutter of dentation, on the lower surface of yarn clipping top cover, is provided with the yarn clipping flange, and this yarn clipping flange is corresponding with the upper end position that pincers is held sliding sleeve.The Yarn cutter of dentation can be when doffing tube drawing accurate broken yarn, broken yarn is reliable, adopts the yarn clipping of yarn clipping flange to make it pincers and holds more effective.
The further embodiment that this is practical, said fixed cover have been disposed radially 3-6 movable steel ball hole, all are equipped with a movable steel ball in each movable steel ball hole, the corresponding Baltimore groove of each movable steel ball hole.A plurality of movable steel balls are set, make pincers hold sliding sleeve and hold with the closed pincers of yarn clipping top cover and separate steady and smooth more.
Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment to the utility model automatically the pincers spindle of holding the tail yarn do further explain.
Fig. 1 is that the utility model can be held the structural representation of a kind of specific embodiment of spindle of tail yarn by automatic pincers.
