Description

A kind of reducing aluminum alloy bobbin

Technical field

The utility model relates to wrap yarn production and uses aluminum bobbin field, particularly relates to a kind of reducing aluminum alloy bobbin.

Background technology

The bobbin of aluminium matter is important tool indispensable in wrap yarn production process.When wrap yarn is produced, first on bobbin-winding machine, roll up after long filament (being generally terylene or cotton synthetic fibre long filament), then take High Rotation Speed on coating machine, the long filament making the test on bobbin through drawing-off unwinding, carry out the production of wrap yarn, so the size of wrap yarn just depends on bobbin the number around long filament.Because bobbin needs High Rotation Speed on coating machine, the size of bobbin is unsuitable excessive, thereby has limited the capacity of wrapping wire, has also limited the size of wrap yarn.Large volume wrap yarn is formed by connecting by several rouleau wrap yarns conventionally, so joint is many.

It is commonplace that conventional aluminum bobbin is applied on wrap yarn is produced, specification is numerous, but the upper lower burrs size of bobbin is equally large, on surface, capacity is larger, in its tangible process of producing, the long filament that debatching goes out can be encountered the edge of top plate through after the unwinding of a period of time long filament air ring of being everlasting, if the edge of top plate is excessive, will cause resistance excessive and fracture of wire occurs, therefore thickness that can wrapping wire on bobbin greatly reduces, capacity is very limited, and unwinding is not thorough, silk thread loss is large.

Utility model content

The technical matters that the utility model mainly solves is to provide a kind of reducing aluminum alloy bobbin, and commonality is good, and capacity that can wrapping wire is large, and during unwinding, silk thread resistance is little, is difficult for broken string, and silk thread degree of utilization is high.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of reducing aluminum alloy bobbin is provided, comprise: top path disk, middle hollow tubular and large footpath, bottom disk, the center of the large footpath of described top path disk and bottom disk is respectively provided with a circular hole, in the middle of described, hollow tubular is connected between the disk of the large footpath of top path disk and bottom, the outside diameter size of described top path disk is less than the diameter dimension of large footpath, bottom disk, described top path disk, the material that middle hollow tubular and large footpath, bottom disk adopt is aluminum alloy.

In preferred embodiment of the utility model, central axis and the large footpath of top path disk and the bottom disk of described middle hollow tubular are perpendicular.

In preferred embodiment of the utility model, the outside diameter of described top path disk is of a size of 76mm or 84mm.

In preferred embodiment of the utility model, the outside diameter of large footpath, described bottom disk is of a size of 110mm.

In preferred embodiment of the utility model, the exradius of described middle hollow tubular is 18mm, and the wall thickness of described middle hollow tubular is 3mm.

In preferred embodiment of the utility model, on the edge of the large footpath of described top path disk and bottom disk, be respectively arranged with rounding.

The beneficial effects of the utility model are: a kind of reducing aluminum alloy bobbin that the utility model is pointed out, during design, the diameter of top path disk is significantly less than the diameter of large footpath, bottom disk, and weight saving is applicable to High Rotation Speed more, during unwinding, silk thread is difficult for encountering top path disk, resistance is little, do not break, so the safe capacity of silk thread is larger, unwinding is thorough, the loss of silk thread is few, has wide range of applications, and is particularly suitable for making the non junction wrap yarn of large volume.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:

Fig. 1 is the structural representation of a kind of reducing aluminum alloy of the utility model bobbin one preferred embodiment;

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

In accompanying drawing, the mark of each parts is as follows: 1, top path disk, 2, middle hollow tubular, 3, large footpath, bottom disk.

The specific embodiment

Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1 to Fig. 2, the utility model embodiment comprises:

A kind of reducing aluminum alloy bobbin, comprise: top path disk 1, the large footpath of middle hollow tubular 2 and bottom disk 3, the center of the large footpath of described top path disk 1 and bottom disk 3 is respectively provided with a circular hole, in the middle of described, hollow tubular 2 is connected between the large footpath of top path disk 1 and bottom disk 3, the outside diameter size of described top path disk 1 is less than the diameter dimension of large footpath, bottom disk 3, the material that described top path disk 1, the large footpath of middle hollow tubular 2 and bottom disk 3 adopt is aluminum alloy, can integrally casting moulding, then fine limit work and polishing.

A kind of reducing aluminum alloy of the utility model bobbin is the improvement of carrying out on common aluminum alloy bobbin, maximum feature is the diameter dimension that the outside diameter size of top path disk 1 is significantly less than large footpath, bottom disk 3, while avoiding unwinding, yarn and top path disk 1 contacts as far as possible, resistance is little, be difficult for broken string, in the middle of described, central axis and the large footpath of top path disk 1 and the bottom disk 3 of hollow tubular 2 are perpendicular, and concentricity is guaranteed, are applicable to High Rotation Speed.

Further, the outside diameter of described top path disk 1 is of a size of 76mm or 84mm, and the capacity of wrapping wire is different, is generally 750 ~ 800g, and the capacity of outside diameter size 84mm is large, and the identical bobbin appearance silk amount of traditional upper lower burrs is 500 ~ 550g.

Further, the outside diameter of large footpath, described bottom disk 3 is of a size of 110mm, measure-alike with common winder, matches with equipment.
