The winding reel of spinning frame

Technical field

The present invention relates to spinning frame winding reel (Bobbin for spinning frame), relating to axle bush in more detail is plugged in around the spindle tip among the spinning frame winding reel, it is characterized by the copper that plugs with 10～80 weight %, the zinc alloying of the nickel of 10～80 weight % and 10～80 weight %, with tetrafluoro polyethylene coating inner face, thickness is the spinning frame winding reel of the following axle bush of 0.3mm.

Background technology

Spinning technology is to twist thread after the rove (roving) that group is made among the spinning process is entried by required thickness and make the technology of line, is the technology that the last process of weaving has the greatest impact to the quality or the production efficiency of product than other any technologies.

Using maximum spinning frames in spinning technology is ring throstle, at ring throstle winding reel is clipped in spindle (spindle) lining, twist, reel according to spindle rotation, because of the line output almost according to this spindle quantity (radical) decision, the scale of spinnery is with this spindle quantitaes.

General traditional spinning frame as shown in Figure 9 is provided with the circumferential groove (100a) of some with winding reel (100) on the side periphery of (300) etc. respectively curling to spin by the state that is parallel to each other, form embedding in the bottom and in the embedding of spinning frame spindle and portion, and use with plastic shaping.

And, in spinning technology according to the elevating movement repeatedly of the circular rails (not shown) on the side periphery of above-mentioned traditional winding reel (100) a certain amount of spinning (300) of curling.

And, in spinning technology spindle and winding reel combination formation as shown in Figure 6, the contact portion of the spindle tip (21) and winding reel (10) inner face is worn easily because of rubbing when rotating at a high speed, uses so plug axle bush (11) around the spindle tip among the spinning frame winding reel.(just, Fig. 6 is applicable to the present invention, and winding reel (10) is identical with the winding reel (100) of Fig. 9, and spindle (20) is identical with the spindle (200) of Fig. 9, and axle bush (11) is identical with the axle bush (110) of Fig. 8.)

Use the phenolic resins of thermosetting resin or molding for epoxy resin thickness to be the axle bush of 1.2～1.4mm and to be plugged in the inner use of winding reel at above-mentioned as shown in Figure 8 axle bush of the past (110), the spindle rotation number is 17 in the past, about 500rpm, and be increased to 25 recently, more than the 000rpm, increased the friction of spindle taper branch and the inner axle bush of winding reel, and heavy wear axle bush, not only can not play the function of axle bush fully, and during with various fiber blend, especially, according to the convergent force and the elastic force compression winding reel of polyester fiber, increase the tightness of winding reel and spindle during with the polyester fiber blending, especially increase the tightness of the axle bush and the spindle tip of winding reel, and the vibrations on increase winding reel top, therefore increase the defect rate of the form of twisting thread, become the lost of life reason of the spindle bearing that is plugged in spindle inside, according to the wearing and tearing of axle bush, the crack takes place in the position that the buckling phenomenon of winding reel takes place or plug axle bush, and weaving goes wrong.

And, attached to the spindle tip of spindle and be plugged in the phenolic resins of winding reel inside or during epoxy resin axle bush doff (Doffing :) for twist yarn inserts winding reel the process that comes off the spindle tip and axle bush produce ammonia according to the frictional heat of moment friction, therefore harmful, winding reel produces the crack during winding reel made of polycarbonate resin or ABS resin, not only can not use winding reel, and can not weave.

Especially, nearest spinning frame is provided with a plurality of spindles, carries out the insertion of winding reel automatically and comes off, and therefore stops the starting of spinning frame when any one winding reel around spiral does not separate among the spindle, not only reduces productivity, and causes the confusion of technology.

And, making rotation number is 30, what become problem most during the above spinning frame of 000rpm is that axle bush by traditional approach uses phenol or epoxide materials, therefore when 27, buoyancy was greater than the frictional force between winding reel and the axle bush when the above ultrahigh speed of 500rpm was rotated, and axle bush is from more than the about 2～3mm of spindle contact site emersion.(with reference to Figure 10)

Strengthen the degree that rolls of winding reel front end like this during the winding reel emersion, can not satisfy the desired degree of up-to-date spinning frame (the vibrations scope of winding reel front end≤0.25mm), and occurred problem when producing senior yarn.

Summary of the invention

Therefore, the object of the present invention is to provide intensity that improves axle bush and the axle bush of making minimal thickness, thickening plugs the winding reel thickness of axle bush part relatively, the twisted phenomena that prevents winding reel makes it only to take place fine vibrations, do not take place not produce the crack according to the ammonia of the spindle tip and axle bush frictional heat, almost there are not wearing and tearing, the spinning frame winding reel of weaving with best condition.

And, other purpose of the present invention is to form male and fomale(M﹠F) on the periphery of axle bush, at the inner groove that sandwiches the spindle tip that forms of axle bush, even rotating winding reel also prevents axle bush and winding reel at a high speed, the perhaps mutual idle running phenomenon between axle bush and the spindle, especially prevent the phenomenon of axle bush along spindle axle emersion, the value of rolling of needed winding reel front end remains to below the 0.25mm when producing senior yarn.

Not only for above-mentioned purpose, and in order to realize other purposes, at the copper of the present invention with 10～80 weight %, the zinc alloying of the nickel of 10～80 weight % and 10～80 weight %, with tetrafluoro polyethylene coating inner face, thickness is that the following axle bush of 0.3mm is plugged in around the spindle tip among the spinning frame knitting wool tube to make winding reel, make it only to take place fine vibrations, ammonia does not take place or not the crack, wear and tear hardly, thereby obtain spinning frame winding reel with the weaving of best condition.
