Description

Technical Field

[0001] This utility model relates to the technical field of fiber product manufacturing equipment, specifically to a semi-automatic self-stop device for braiding glass fiber preform tubes after thread breakage. Background Technology

[0002] In the process of fiberglass preform weaving, multiple fiberglass yarns are interwoven on a braiding machine to form a tubular structure. Due to the fineness of the fiberglass yarns and their susceptibility to uneven tension and friction, yarn breakage may occur during weaving. Traditional production relies mainly on manual inspection, which suffers from slow response and high scrap rates. Existing yarn breakage detection devices are mostly used in the textile industry, but the unique characteristics of fiberglass (high hardness, susceptibility to static electricity, and tendency to burr) result in high false alarm rates and poor adaptability for general-purpose detection devices. Therefore, there is an urgent need for a yarn breakage self-stopping device specifically designed for fiberglass preform weaving. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-3 As shown, a semi-automatic fiberglass preform braiding self-stop device includes a working frame 1 and a support frame 2. The support frame 2 is positioned above the working frame 1. Multiple fixed ring motors 3 and fixed rings 4 are installed at the upper end of the working frame 1. Multiple rotating disks 5 are installed at the upper end of the fixed rings 4, and multiple fiber rollers 6 are installed at the upper end of the rotating disks 5. Each fiber roller 6 is equipped with a sensor 7. A fixed ring beam 8 is installed in the middle of the fixed rings 4, and a beam support column 14 is installed on the fixed ring beam 8. The beam support column 14 is connected to the support frame 2. An adjusting frame 15 and a preform braiding device 11 are installed on the support frame 2. Braiding support frames 10 are installed on both sides of the preform braiding device 11, and a braiding motor 12 is installed on one side of the braiding support frame 10. An adhesive ring 9 is installed on the adjusting frame 15, and a conveying pipe 13 is installed on one side of the support frame 2.

[0019] The fixed ring 4 is internally connected to multiple fixed ring motors 3. Multiple limiting rings are set on the rotating disk 5. The limiting roller 6 is connected to the limiting rings, and the fiber roller 6 is fixedly connected to the sensor 7. The braiding motor 12 is fixedly connected to the support frame 2. The braiding support frame 10 is internally connected to the braiding motor 12, and the output end of the braiding motor 12 is connected to the billet tube braiding device 11. A boss is set on one side of the work frame 1, and the boss is fixedly connected to the conveying pipe 13, which is located below the billet tube braiding device 11.

[0020] During operation, the glass fiber threads on the fiber roller 6 are hung on the sensor 7, and then the fiber threads are passed through the glue-coating ring 9 through the sensor 7. Multiple glass fiber threads are then hung on the blank tube braiding device 11. The fixed ring motor 3 is started, and multiple fixed ring motors 3 drive the fixed ring 4 and the rotating disk 5 to rotate. Multiple glass fiber threads begin to be wound and bonded together through the glue-coating ring 9, and then pass through the blank tube braiding device 11 to form a fiber blank tube, which is then transported out through the conveying pipe 13. The sensor 7 is electrically connected to multiple fixed ring motors 3 and to the braiding motor 12. When the fiber threads on the fiber roller 6 are used up, the sensor 7 receives a signal and transmits it to the fixed ring motors 3 and the braiding motor 12 to stop.
