Description

Technical Field

[0001] The utility model relates to the technical field of fiber raw yarn plying equipment, in particular to an inorganic fiber unwinding yarn frame with adjustable porcelain eye direction. Background Art

[0002] The plying process can ply the fiber raw yarns of small bundles into large bundles of untwisted roving. The equipment involved mainly includes unwinding yarn frame, tension frame, untwisting machine, etc. Among them, the unwinding yarn frame is generally composed of a bracket, a porcelain eye and a porcelain eye strip. Multiple porcelain eyes can be installed on a porcelain eye strip. The porcelain eye, also known as the thread collector, can reduce the friction force on the fiber raw yarn when plying.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0033] See also Figure 1-Figure 6 , an inorganic fiber unwinding yarn frame with adjustable porcelain eye direction, comprising a bracket 1, a porcelain eye strip 2 is rotatably connected to the bracket 1, at least one end of the porcelain eye strip 2 comprises a connecting shaft 21, the connecting shaft 21 is penetrated through the bracket 1 so that the porcelain eye strip 2 can rotate relative to the bracket 1, as one embodiment, both ends of the porcelain eye strip 2 have a connecting shaft 21, and the corresponding connecting shafts 21 are respectively rotatably assembled on the bracket 1, such as Figure 3 shown.

[0034] In this embodiment, the outer end of the connecting shaft 21 passes through the side wall of the bracket 1 and a knob 3 is fixed on the end thereof passing through the side wall of the bracket 1. The knob 3 is arranged on the outside of the bracket 1. When the knob 3 rotates, the porcelain eye strip 2 rotates synchronously therewith, so that the staff can adjust the angle of the porcelain eye strip 2.

[0035] One or more ceramic eyes 4 are installed on the ceramic eye strip 2. The ceramic eyes 4 include through holes 41 for the fiber filaments 5 to pass through. As one option, the ceramic eyes 4 are fixed on the ceramic eye strip 2 evenly and equidistantly.

[0036] Adjustment of the angle of the eyelet strip 2 also causes the angle of the eyelet 4 to be adjusted synchronously. As one implementation method, the adjustment angle can be selected to make the retreat direction of the fiber filament 5 and the direction of the eyelet 4 about 45°, so as to greatly reduce the friction force borne by the fiber filament and improve the quality of the roving.

[0037] In order to facilitate the staff to determine the adjusted angle, in this embodiment, the bracket 1 is fixedly provided with an angle dial 6, and the knob 3 includes an indicating unit that matches the angle dial 6, and the indicating unit can be an indicating needle or an indicating mark, etc. As one option, the angle dial 6 is fixedly provided on the outer side wall of the bracket 1.

[0038] In this embodiment, a first positioning unit 7 is disposed on the eye strip 2 . As one implementation mode, the first positioning unit 7 is fixed at the end of the eye strip 2 , such as on the connecting shaft 21 , and can be arranged on the inner side of the bracket 1 .

[0039] The bracket 1 is provided with a second positioning unit 8 for cooperating with the first positioning unit 7, which has a first position separated from the first positioning unit 7 and a second position cooperating with the first positioning unit 7. When the second positioning unit 8 is in the second position, the ceramic eye strip 2 is positioned.

[0040] The specific structures of the first positioning unit 7 and the second positioning unit 8 may be in various forms, such as the following forms:

[0041] First, the first positioning unit 7 is a gear, and the second positioning unit 8 is a positioning screw. The second positioning unit 8 is threadedly connected to the bracket 1, and its movement trajectory can be longitudinal movement. The second positioning unit 8 is rotated to make it close to or away from the first positioning unit 7. When the outer end of the positioning screw is against the gear or stuck in the gap on the gear, the porcelain eye strip 2 is positioned.

[0042] Secondly, a plurality of grooves are circumferentially opened on the outer wall of the first positioning unit 7. The second positioning unit 8 is a positioning screw, which is threadedly connected to the bracket 1. Its movement trajectory can be longitudinal movement. The second positioning unit 8 is rotated to make it closer to or farther away from the first positioning unit 7. When the outer end of the positioning screw is inserted into the corresponding groove, the porcelain eye strip 2 is positioned.

[0043] Thirdly, the first positioning unit 7 is a magnet, and a limiting hole is provided on the bracket 1. The second positioning unit 8 is movably arranged at the limiting hole. The second positioning unit 8 is a magnet. The first positioning unit 7 and the second positioning unit 8 are magnetically attracted to each other. The movement trajectory of the second positioning unit 8 can be longitudinal movement. After adjusting to a suitable angle, the second positioning unit 8 is pushed up to make it magnetically attracted to the first positioning unit 7. At this time, the lower end of the second positioning unit 8 is still located at the limiting hole, and the second positioning unit 8 is limited by the hole wall of the limiting hole. When the second positioning unit 8 is magnetically attracted to the first positioning unit 7 and at least part of the second positioning unit 8 is located in the limiting hole, the porcelain eye strip 2 is positioned.

[0044] Fourthly, a plurality of holes are opened circumferentially on the side wall of the first positioning unit 7, and the second positioning unit 8 is a pin shaft, which is passed through the side wall of the bracket 1, and its movement trajectory can be lateral movement. When the outer end of the pin shaft is inserted into the hole, the porcelain eye strip 2 is positioned.
