Abstract

The utility model discloses a kind of Teflon bobbins, comprise the Teflon resin layer of substrate layer and inside and outside both sides, outside the Teflon resin layer of described outside, be also provided with the second Teflon resin layer.Teflon bobbins of the present utility model, has easy cleaning, and work-ing life extends, the advantage that intensity increases.

Description

Teflon bobbins

Technical field

The utility model belongs to glass fiber wire-drawing technical field, is specially a kind of glass fiber wire-drawing Teflon bobbins.

Background technology

The bobbins during production of existing glass fibre, precursor being wrapped in mandrel carries out wire-drawing operation, and then precursor is placed in drying oven together with bobbins heat-treats, after finally carrying out moving back solution with specific equipment, make marketable yarn.The severe environment such as high speed, high temperature and corrosion will be stood in treating processes due to precursor, and at bobbins high speed rotating on head, high to its requirement of strength.

Existing bobbins structure comprises Teflon resin layer three layers of mechanism of substrate layer, hot composite base sheet material layers both sides in addition, the bobbins of this structure can Reusability, but still also exist not enough: when reusing, outside need is through cleaning, bobbins after repeatedly cleaning, its work-ing life reduces, and is positioned at high speed rotating on head again, insufficient strength after repeatedly using.

Utility model content

The purpose of this utility model overcomes bobbins of the prior art cleaning to shorten rear work-ing life, and the deficiency of insufficient strength, provides a kind of convenient cleaning, the Teflon bobbins that intensity increases.

The technical solution of the utility model is achieved in that a kind of Teflon bobbins, comprises the Teflon resin layer of substrate layer and inside and outside both sides, is also provided with the second Teflon resin layer outside the Teflon resin layer of described outside.

As preferably, described second Teflon resin layer is compound in the outside of outside Teflon resin layer by heat.

Compared with prior art, Teflon bobbins of the present utility model, has easy cleaning, and work-ing life extends, the advantage that intensity increases.

Accompanying drawing explanation

Fig. 1 is the utility model bobbins schematic cross-section;

Fig. 2 is the structural representation of the utility model bobbins.

Shown in figure: 1, substrate layer, 2, Teflon resin layer, the 3, second Teflon resin layer.

Embodiment

Embodiment of the present utility model is as follows:

Embodiment: as shown in Figure 1: a kind of Teflon bobbins, comprises the Teflon resin layer 2 of substrate layer 1 and inside and outside both sides, and outside the Teflon resin layer of described outside, also heat is compounded with the second Teflon resin layer 3.

Above-mentioned Teflon bobbins, has easy cleaning, and work-ing life extends, the advantage that intensity increases.

Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to above-described embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, all should think protection domain of the present utility model.

Claims (2)

1. a Teflon bobbins, comprises the Teflon resin layer of substrate layer and inside and outside both sides, it is characterized in that, is also provided with the second Teflon resin layer outside the Teflon resin layer of described outside.

2. Teflon bobbins according to claim 1, is characterized in that, described second Teflon resin layer is compound in the outside of outside Teflon resin layer by heat.
