Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. For the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Please refer to Figures 1-13 , an aramid fiber spinning equipment, including the main body of the spinning equipment 1 and the support frame body 4. A wire guiding roller 2 is arranged at the top of the main body of the spinning equipment 1, and a wire gathering mechanism 3 is arranged at the front side of the main body of the spinning equipment 1. A support seat body 5 is fixedly arranged at the bottom end of the support frame body 4; among them, installation thread grooves 41 are equidistantly arranged on the side wall of the support frame body 4, and the support frame body 4 is connected with the strip warping auxiliary mechanism.

[0037] When multiple silk threads for textile processing pass through the sectional warping auxiliary mechanism, the silk threads are placed in the wire guiding grooves of the wire guiding cylinders. After the placement is completed, the cooperating cover plate 801 is pressed on the supporting cross bar 601. At the same time, the engaging grooves 901 at both ends of the auxiliary cover body 808 located at the bottom side of the cooperating cover plate 801 are in engaging contact with the funnel-shaped cover body 708. The auxiliary cover body 808 and the wire guiding cylinders provide a limiting effect on the silk threads. Then, the multiple silk threads pass through the wire gathering mechanism 3 and are conveyed to the spinning equipment main body 1 through the wire guiding rollers 2. In this process, there is no need to pass the silk threads through the limiting holes one by one for sectional warping. Multiple strands of silk threads can be placed and separated simultaneously, reducing the operation difficulty of the staff and playing a positive role in improving the spinning efficiency.

[0038] The supporting cross bar 601 is fixedly connected to the support frame body 4 through the mounting plate head 602. The mounting screw 604 for connection is provided with a first handle 605 at its end, aiming to facilitate the tightening and loosening operations of the mounting screw 604, thereby facilitating the disassembly, assembly, and position adjustment of the supporting cross bar 601 and making it have better working flexibility. That is, the sectional warping auxiliary mechanism includes a supporting cross bar 601, a mounting plate head 602, a first mounting hole 603, a mounting screw 604, a first handle 605, a sectional limiting component, and a connecting fitting. Mounting plate heads 602 are symmetrically and fixedly arranged at both ends of the supporting cross bar 601. The first mounting hole 603 is provided on the mounting plate head 602. The mounting plate head 602 is fixed by the mounting screw 604. A first handle 605 is fixedly arranged at one end of the mounting screw 604. The number of groups of the supporting cross bar 601 arranged on the support frame body 4 can be selected according to actual needs, and the distance and height between the supporting cross bars 601 can be adjusted.

[0039] When multiple silk threads are inspected and observed, and the silk threads that do not meet the production quality requirements are replaced and corrected in a timely manner. When replacing a single silk thread at this time, there is no need to remove the sectional warping auxiliary mechanism as a whole. Just pull up the auxiliary pull head 806 at the corresponding position of the silk thread. The auxiliary pull head 806 drives the movable pin 805 to move upward, thereby driving the auxiliary cover body 808 to move upward. Then, the silk thread can be processed in a timely manner, providing great convenience for the staff's observation and inspection work during the spinning process.

[0040] Furthermore, during the silk thread slitting process, the slitting warping auxiliary mechanism provided in the present scheme can provide a slitting limit function while also providing a cleaning effect on the conveyed silk thread, thereby avoiding contamination of the silk thread when passing through the slitting warping auxiliary mechanism, that is, when the height position of the support frame 4 is higher than the silk gathering mechanism 3, the silk thread is in the position of the silk guide groove on the silk guide cylinder, and when the support frame 4 is lower than the silk gathering mechanism 3, the silk thread passes through the auxiliary cover body 808, that is, a slitting limit component is provided in the support cross bar 601, and the slitting limit component includes a placement groove 701, a connecting thread groove 702, a support plate 703, a second mounting hole 704, an auxiliary bearing 705, a connecting shaft 706, a sealing head 707, a bucket-shaped cover body 708, an auxiliary through hole 709 and a docking thread groove 710; the placement grooves 701 are equidistantly arranged at the top of the support cross bar 601, and the inner The side wall is symmetrically provided with connecting thread grooves 702, a second mounting hole 704 is provided in the support plate 703, and the support plate 703 is fixedly connected to the side wall of the placement groove 701 by screws, and the docking thread groove 710 is provided on the support cross bar 601, and the docking thread groove 710 is connected to the connecting accessory; an auxiliary bearing 705 is fixedly provided on one side of the support plate 703, and the auxiliary bearing 705 is sleeved and provided at one end of the connecting shaft 706, and the other end of the connecting shaft 706 is fixedly connected to the plugging head 707; the plugging head 707 is fixedly provided in the bucket-shaped cover body 708, and the side wall of the bucket-shaped cover body 708 is provided with an auxiliary through hole 709; the two bucket-shaped cover bodies 708 are docked to form a wire guide tube, the small ends of the two bucket-shaped cover bodies 708 are docked, and a wire guide groove body is formed in the middle of the wire guide tube, and a wire guide tube is provided in a placement groove 701.

[0041] When the silk thread passes through the wire guide groove on the wire guide cylinder, the impurities adhering to the silk thread are scraped off, and the scraped impurities generally fall down directly, and some of them enter the auxiliary through hole 709 on the wire guide cylinder, and then fall down from the bucket-shaped cover body 708. The purpose of setting the auxiliary through hole 709 here is to improve the effect of impurity removal and prevent the scraped impurities from adhering to the silk thread when the silk thread passes through the wire guide groove. In addition, the bucket-shaped cover body 708 in this scheme can be rotated by the auxiliary bearing 705 and the connecting shaft 706. That is, when the silk thread passes through the wire guide groove position, when the friction force is too large, it will drive the bucket-shaped cover body 708 to rotate, and try to avoid the wire guide groove on the bucket-shaped cover body 708. The wire causes friction damage to the wire, ensuring the quality of the wire body, wherein the support plate 703 is fixedly connected to the inner wall of the placement groove 701 by screws, and it is detachably arranged, that is, it provides a convenience when the wire guide cylinder needs to be replaced or the cleaning position is needed later.

[0042] When the silk thread passes through the auxiliary cover 808, the protective cushion body 903 and the auxiliary soft hair cushion strip 904 arranged inside the auxiliary cover 808 provide a cleaning effect on the silk thread. That is, the connecting fitting includes a matching cover plate 801, a through hole 802, a docking screw 803, a knob head 804, a movable bolt 805, an auxiliary pull head 806, an auxiliary spring body 807, an auxiliary cover 808 and an auxiliary structure; a through hole 802 is arranged on the matching cover plate 801, the docking screw 803 passes through the through hole 802 and is threadedly connected with the docking thread groove 710 on the support cross bar 601, and a knob head 804 is fixedly arranged at one end of the docking screw 803. Movable bolts 805 are equidistantly and movably inserted in the matching cover plate 801; an auxiliary pull head 806 is fixedly arranged at the top end of the movable bolt 805. The auxiliary pull head 806 is set as a round block. An auxiliary cover 808 is fixedly arranged at the bottom end of the movable bolt 805. An auxiliary spring body 807 is fixedly arranged at the end of the auxiliary pull head 806 connected to the movable bolt 805, and the other end of the auxiliary spring body 807 is fixedly arranged on the top side of the matching cover plate 801. The auxiliary cover 808 corresponds to the position of the wire guide cylinder in the placement groove 701 and has the same number of sets; the auxiliary cover 808 is set as a C-shaped plate, and an auxiliary structure is arranged on the auxiliary cover 808. The auxiliary structure includes a clamping groove body 901, an auxiliary movable ball 902, an elastic protective cushion body 903 and an auxiliary soft hair cushion strip 904; the clamping groove bodies 901 are symmetrically arranged at both ends of the auxiliary cover 808, and auxiliary movable balls 902 are equidistantly and movably embedded in the inner side walls of the clamping groove bodies 901. The elastic protective cushion body 903 is fixedly arranged on the inner side wall of the auxiliary cover 808, and an auxiliary soft hair cushion strip 904 is arranged inside the elastic protective cushion body 903.

[0043] The matching cover plate 801 and the support cross bar 601 are arranged to cooperate with each other. That is, the matching cover plate 801 is fixedly connected to the support cross bar 601 through the docking screw 803. The knob head 804 arranged at one end of the docking screw 803 is also for the purpose of facilitating the tightening and loosening of the docking screw 803, and thus facilitating its later disassembly and assembly work. In this process, the purpose of splicing the matching cover plate 801 and the docking screw 803 is, on the one hand, when the silk thread is initially divided and sorted, the silk thread can be directly placed in the wire guide groove on the wire guide cylinder. Compared with the existing simple use of a limit hole for wire splitting, there is no need to thread each wire one by one, which is troublesome to operate. And when the silk thread passes through the simple limit hole, especially when the position of the limit hole is higher or lower than the wire gathering mechanism 3 on the spinning equipment main body 1, the silk thread will contact the inner side wall of the limit hole, and during the silk thread conveying process, the silk thread will inevitably cause scratching damage to its inner side wall, which has a negative impact on the quality of the silk thread body and even causes the problem of the silk thread breaking, affecting the working efficiency of the spinning process.

[0044] In order to further improve the flexibility of the silk thread during the observation and detection work, for the silk thread with quality problems, multiple groups of movable pins 805 are equidistantly arranged on the matching cover plate 801 in this solution, and an auxiliary cover body 808 is arranged at the bottom end of the movable pin 805. The auxiliary cover body 808 is used in cooperation with the wire guide cylinder in the placement groove 701 to meet the requirements of the strip spinning process of the silk thread, and can also provide a corresponding cleaning effect on the silk thread. Moreover, when it is necessary to process a certain strand or multiple strands of silk thread, only need to lift the auxiliary cover body 808 at the position of the problem silk thread, so that the engaging groove body 901 at the end of the auxiliary cover body 808 is separated from the side wall of the funnel-shaped cover body 708, that is, by pulling up the auxiliary pull head 806, the auxiliary pull head 806 drives the movable pin 805 to move upward, and finally drives the auxiliary cover body 808 to be lifted. After that, move the silk thread to the outside of the auxiliary cover body 808. For the newly added silk thread, after passing through the placement groove 701, then move the silk thread to the inside of the auxiliary cover body 808. In this process, it is also necessary to pull up the auxiliary pull head 806 in advance to create a gap between the auxiliary cover body 808 and the funnel-shaped cover body 708, and then move the silk thread to the inside of the auxiliary cover body 808. Finally, release the auxiliary pull head 806, and the auxiliary cover body 808 is reset under the rebound action of the auxiliary spring body 807, that is, the engaging groove bodies 901 at both ends of the auxiliary cover body 808 are stuck on the funnel-shaped cover body 708. Here, auxiliary movable balls 902 are also arranged on the inner side wall of the engaging groove body 901. Its function is to avoid affecting the rotation of the funnel-shaped cover body 708 when the engaging groove body 901 is clamped with the funnel-shaped cover body 708.

[0045] During the actual processing operation, according to the actual use requirements, the height positions of the support cross bars 601 on the support frame body 4 can also be higher than the wire gathering mechanism 3 on the spinning equipment main body 1. In this way, the silk threads will all pass through the wire guide grooves on the wire guide cylinders. That is, at this time, the connection fittings can be not used, that is, there is no need to install the matching cover plate 801 anymore. In this way, the wire splitting operation of the silk thread and the subsequent detection work are more convenient. Among them, when it is necessary to set a large number of support cross bars 601 on the support frame body 4, that is, some of the positions of the support cross bars 601 are higher than the wire gathering mechanism 3, and some are lower than the wire gathering mechanism 3. At this time, for the support cross bars 601 lower than the wire gathering mechanism 3, either use the connection fittings to split and convey the silk thread; or the support cross bars 601 can be disassembled and installed in the reverse direction, that is, make the end of the support cross bar 601 with the placement groove 701 face downward. In this way, the silk thread will also be closely attached to the wire guide grooves on the wire guide cylinders during the conveying process. The working flexibility of this solution is excellent and can better meet the actual spinning production requirements.

[0046] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
