[0026] The following is combined Figures 1 to 6 The embodiments of this utility model will be described in detail below.

[0027] like Figures 1 to 3 As shown, a protective device for the production of easily dyed polyurethane fine denier filaments includes: a bracket 2 disposed between the spinning channel outlet 3 and the guide 4, and protective plates 1 clamped on both sides within the bracket 2. There are two brackets 2. In other embodiments, the same end of the two brackets 2 can also be connected to form a U-shaped structure, clamping the protective plates 1 from three sides (not shown). The protective plates 1 have notches 11 for the passage of spandex filament bundles 5. The protective plates 1 are generally U-shaped, and the spacing of the notches 11 is preferably 3cm, which is the spacing of the spandex filament bundle 5 channel. The spacing of the notches 11 can be adjusted according to the actual range of the spandex filament bundle 5's forward and backward offset during production. The notches 11 are rectangular or a combination of rectangle and semicircle. The bracket 2 is an I-shaped structure, but an L-shaped bracket 6 or a C-shaped bracket 7 can also be used.

[0028] After the subsequent operations of spinning and lifting are completed, such as cleaning, maintenance, and replacement of spinning components, the yarn bundle is put back into the spinning tunnel to resume production. After the spandex yarn bundle 5 comes out of the spinning tunnel outlet 3 and passes through the guide 4 to complete the spin-forming process, the notch edge of the protective plate 1 is aligned with the spandex yarn bundle 5 and the protective plate 1 is snapped into the bracket 2. Because a large operating space is required during the spin-forming process, the protective plate 1 can only be snapped into the bracket 2 after the spin-forming process is completed. If black waste yarn falls out of the spinning tunnel outlet 3, since the notch 11 of the protective plate 1 is small and the area of ​​the protective plate 1 is large, the black waste yarn will most likely fall on the protective plate 1, avoiding direct fall onto the guide 4 or the winding equipment (not shown in the figure) below it, which would cause yarn breakage in the normal spinning position.

[0029] like Figure 4As shown, due to the air conditioning temperature and humidity control, equipment operation and personnel and material flow in the production workshop, air flow will inevitably exist, and if the speed of the protective plate 1 extracted from the support 2 is too fast before cleaning, a larger air flow will also be generated, that is, there is a probability that the black waste silk will be blown off the protective plate 1 onto the guide 4 or the winding equipment (not shown in the figure) below to cause normal spinning position broken silk. Therefore, the edge of the protective plate 1 can also be provided with a side plate 12, so that the protective plate 1 forms a storage box structure, has a good windproof function, and greatly reduces the risk of black waste silk falling off the protective plate 1. In addition, double-sided adhesive paper (not shown in the figure) can also be attached to the upper surface of the protective plate 1, and the black waste silk falling on it will be adhered, further reducing the risk of black waste silk falling off the protective plate 1, and replacing new adhesive paper when cleaning.

[0030] As shown in Figure 5 and Figure 6 shown, the protective plate 1 is respectively provided with two T-shaped key grooves 14 perpendicular to the length direction of the notch 11 on the left and right sides of the notch 11, and each side of the two T-shaped key grooves 14 is close to the front and rear ends of the notch 1. The protective plate 1 is also respectively provided with a sliding baffle 13 on the left and right sides of the notch 11, and the front and rear ends of the lower surface of the sliding baffle 13 are respectively provided with T-shaped keys 133 matched with the T-shaped key grooves 14. Each end of the T-shaped key 133 is preferably two, so that the sliding baffle 13 can be clamped into the T-shaped key groove 14 and slide left and right. The front and rear ends of the sliding baffle 13 are also provided with through holes 131, and the through holes 131 are provided with fastening screws 132. The screw rod of the fastening screw 132 is abutted against the bottom of the T-shaped key groove 14 by rotating the fastening screw 132, thereby fixing the position of the sliding baffle 13 on the protective plate 1. The vicinity of the T-shaped key groove 14 is also provided with a scale table 15 for accurately adjusting the position of the sliding baffle 13 on the protective plate 1. The gap between the notches 11 of the protective plate 1 designed in this way can be set to be greater than 3 cm, such as 5 cm. The gap between the sliding baffles 13 on both sides of the notch 11 is used as the gap of the spandex silk bundle 5 channel. When the stability of the production equipment improves, such as the front and rear offset distance of the spandex silk bundle is less than 2 cm, the positions of the left and right sliding baffles 13 can be adjusted so that the distance between them is 2 cm, further reducing the area of the interception blind area and improving the interception rate of black waste silk; when the production equipment is unstable for a short period of time, such as the front and rear offset distance of the spandex silk bundle 5 reaches 4 cm, the distance between the two can also be adjusted to 4 cm to avoid the spandex silk bundle 5 from hitting the sliding baffle 13 and causing broken silk.

[0031] The side plate 12 can also be provided on the side of the sliding baffle 13 close to the notch 11, which does not conflict with the design concept of the side plate 12 in the second embodiment.

[0032] The utility model discloses a protective plate is set up between the spinning channel export and the guide, and the protective plate only reserves the gap of spandex tow, so the black waste silk falling from the spinning channel can be effectively intercepted, the side plate is set up on the edge of the protective plate and forms the storage box structure, so the better windproof function is formed, when the airflow exists in the workshop or the speed of the protective plate is too fast when being drawn out and cleaned, the black waste silk will not fall from the protective plate, and the risk of the black waste silk falling on the protective plate is greatly reduced, the double -sided adhesive paper is attached on the upper surface of the protective plate, so the black waste silk falling on it is adhered, and the risk of the black waste silk falling on the protective plate is further reduced, and the sliding baffle is designed, and the spacing of the sliding baffle can be increased or reduced according to the stability of the production equipment, and the production safety is improved.

[0033] The above embodiments and drawings are not limited to the product shape and style of the utility model, and any ordinary technical personnel in the art can make appropriate changes or modifications, which should be considered as not departing from the patent scope of the utility model.
