Detailed Description

The utility model is further described with reference to the following detailed description and accompanying drawings.

Examples

First, a conventional scheme, i.e., a comparative example, will be described. FIG. 2 shows a model I-QONON-5B-1380/24 winding head device manufactured by Barmag of Germany, which is a twins 24-head winding head. In this conventional solution, including the winder stand 1, the winder stand 1 can be roughly divided into two parts: the upper part is provided with a hot box 2, the position is on the left side of the upper part, and the bottom of the hot box 2 is provided with a hot box outlet wire guide hook 3; the lower part of the winding frame 1 is provided with a pair of winding heads 7, the winding heads 7 are arranged in bilateral symmetry and are positioned at the same horizontal position in height, wherein the winding head 7 at the left side is positioned approximately right below the upper hot box 2. Each winding head 7 is provided with an upper pull rod godet frame 6, and the end part of the upper pull rod godet frame 6 is provided with a winding head upper pull rod godet 5. The upper pull rod wire guide frame 6 on the left winding head 7 inclines upwards and rightwards and is symmetrical with the upper pull rod wire guide frame 6 on the right winding head 7. The FDY tows 4 coming out of the hot box 2 are uniformly divided into two bundles after passing through the godet 3 at the outlet of the hot box, the left bundle passes through the upper pull rod godet 5 of the left winding head and is connected with the left winding head 7, and the right bundle passes through the upper pull rod godet 5 of the right winding head and is connected with the right winding head 7. At this time, in the path through which the left FDY filament bundle 4 passes, a turn is formed at the draw bar filament guide hook 5 on the left winding head, similarly, in the path through which the right FDY filament bundle 4 passes, a turn is also formed at the draw bar filament guide hook 5 on the right winding head, and the turn angle on the left path is obviously smaller than that on the right path, which determines the difference of the stress magnitude when the left and right FDY filament bundles 4 are respectively wound to the left and right winding heads 7, and under the condition that the equipment and the accessories are new, the effect caused by the difference is not obvious, but after the main accessories are used for a period of time, the stress difference can cause the wearing state of the accessories to be different, thereby forming the physical property deviation of the products on the left and right sides.

Taking the production of FDY 83dtex/72F as an example, in the comparative example, the included angle is 159 degrees in the package forming process of the FDY tows 4 from the hot box outlet godet 3 to the left winding head 7 through the left winding head upper pull rod godet 5, and the winding tension of the left FDY tows 4 is measured to be F-12.5 cN; during the package forming process of the FDY tows 4 from the hot box outlet godet 3 to the winding head 7 through the right winding head upper pull rod godet 5, the included angle is 170 degrees, and the measured right tow tension is F ═ 14.6 cN.

The difference of the tension of the FDY tows 4 on the left side and the right side causes the full diameter of the right side spinning cake to be 1-2mm larger than that of the left side spinning cake during the winding process of the FDY tows 4. Meanwhile, the angle of the left side passing through the upper pull rod wire guide hook 5 of the winding head is smaller than that of the right side, and the angle of the left side is sharper, so that the abrasion degrees of porcelain pieces on the upper pull rod wire guide hooks 5 of the left and right winding heads are different after being used for a period of time, and the inherent product quality of the spinning cakes is different. The following table shows the product physical property indexes of the left and right winding heads 7 after the left and right winding heads are used for 3 months by pulling rod wire guides 5 newly installed with porcelain pieces, such as:

the example is a winding structure for producing terylene which can eliminate tension deviation and is improved on the basis of a comparative example. As shown in fig. 1, the main improvement point is on the winding head 7 on the left side, specifically, a fixing frame 8 and a guide wire rod 9 are added. In detail, as shown in fig. 3, the fixing frame 8 is shaped like an inverted L when viewed from the side, the lower end of the inverted L is fixed to the upper rod godet frame 6, the outer end of the upper side of the inverted L extends to the right, and the end of the inverted L is fixed with a godet 9. The wire guide rod 9 is a porcelain-plated wire guide rod, is cylindrical in shape, and is axially parallel to the winding axis of the winding head 7. The winding head upper pull rod wire guide hook 5 is positioned on the upper pull rod wire guide frame 6, and the wire guide rod 9 is positioned right above the left winding head upper pull rod wire guide hook 5 in the whole view, so that a connecting line between the hot box outlet wire guide hook 3 and the left winding head upper pull rod wire guide hook 5 forms a turn at the wire guide rod 9, and a turn is formed between the hot box outlet wire guide hook 3 and the left winding head upper pull rod wire guide hook 5 due to the addition of the wire guide rod 9, and a turn is formed on the winding head upper pull rod wire guide hook 5 from the wire guide rod 9 to the winding head 7.

Similarly, in the example of producing the FDY 83dtex/72F variety, in the example, two upper and lower included angles are formed in the package forming process of the FDY tow 4 from the hot box outlet godet 3 to the left winding head upper pull rod godet 5 to the left winding head 7, the included angle from the hot box outlet godet 3 to the godet 9 is 170 °, the tension of the FDY tow 4 at the position is measured to be F ═ 13.0cN, the included angle from the godet 9 to the winding head upper pull rod godet 5 is measured to be 171 °, and the winding tension of the FDY tow 4 is measured to be F ═ 14.5 cN; during the package forming process of the FDY tows 4 from the hot box outlet godet 3 to the winding head 7 through the right winding head upper pull rod godet 5, the included angle is 170 degrees, and the measured right tow tension is F ═ 14.6 cN. The specific physical property indexes are as follows:

after the adjustment of the embodiment of the present invention, the tension above the pull rod godet 5 on the left and right winding heads was almost uniform, and the three-full lap yarn was continuously observed, and it was found that the difference in the cake package diameter between the left and right winding heads 7 was reduced to within 0.5 mm. The upper pull rod wire guide hook 5 of the winding head is completely replaced by a new porcelain piece, the physical properties of the products of the left and right winding heads are almost the same after 3 months of continuous use, and the abrasion degrees of the upper pull rod wire guide hook 5 of the winding head are consistent. Compared with the prior art, the method has the advantages that the method has obvious technical progress in comparison with the prior art, the deviation of the physical properties of the product is almost small, and the quality of the product is guaranteed.
