Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shunt mechanisms, and particularly relates to a shunt mechanism for drying carbon fiber precursor filaments. Background Art
[0002] In the production process of carbon fibers, the precursor filaments need to be dried to remove moisture and volatile substances after preliminary processing. The drying of the precursor filaments is a key step, which directly affects the quality of the final product. Existing drying devices mainly use hot rollers and hot air for drying. However, since the temperature of the fiber bundle drops after leaving one hot roller and before reaching the next hot roller, this will cause uneven temperature distribution, thereby affecting the quality of the fibers and easily generating hairiness and breakage. Therefore, it is necessary to design a shunt mechanism that can effectively control the direction of the filament bundle and maintain its uniform temperature to improve the drying efficiency and the overall quality of the carbon fiber precursor filaments. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Refer to Figures 1-5, a flow splitting mechanism for drying carbon fiber precursor provided by the utility model includes a base 7. A flow splitting mechanism 1 is arranged at the left end of the base 7. The flow splitting mechanism 1 includes a flow splitting base 101, a flow splitting block 102, a flow splitting pipe 103, a flow splitting guide post 104, a first roller fixing seat 105, a connecting block 106, a first roller 107, a fastening nut 108, a round hole 109, and a connecting bolt 110. A bracket 6 is fixedly arranged on the base 7, a third roller fixing seat 4 is fixedly arranged on the bracket 6, a third roller 3 is arranged on the third roller fixing seat 4, a connecting rod 5 is arranged inside the bracket 6, the connecting rod 5 is connected to a drying cylinder 2, and the precursor evenly split by the flow splitting mechanism 1 is dried by the drying cylinder 2.
[0021] Among them, the flow splitting block 102 is fixedly connected to the flow splitting base 101 through a connecting bolt 110. A round hole 109 is arranged on the flow splitting block 102. The flow splitting guide post 104 passes through the round hole 109 and is fixed by a fastening nut 108. A flow splitting pipe 103 is arranged on the flow splitting base 101. A first roller fixing seat 105 is arranged on the flow splitting base 101. A first roller 107 is arranged on the first roller fixing seat 105. A connecting block 106 is arranged at the end of the flow splitting base 101; the flow splitting pipe 103 is located on the left side of the flow splitting block 102, the first roller 107 is located on the right side of the flow splitting block 102, and the precursor passes from the flow splitting pipe 103 to the flow splitting block 102 and is then pulled to the drying cylinder 2 by the first roller 107; two symmetrically arranged flow splitting pipes 103 are provided; a second roller fixing seat 8 is fixedly arranged on the base 7, a second roller 9 is arranged on the second roller fixing seat 8, and the precursor dried by the drying cylinder 2 is pulled to the third roller 3 by the second roller 9.
[0022] Working process: First, pass the carbon fiber precursor through the middle position of the flow splitting pipe 103, and then pull the passed carbon fiber precursor to the flow splitting block 102. The carbon fiber precursor sequentially passes through the intervals between the flow splitting guide posts 104 on the flow splitting block 102. The carbon fiber precursor passing through the intervals is pulled out along the lower side of the first roller 107 to the drying cylinder 2. As the first roller 107 rotates, the carbon fiber precursor is evenly distributed on the drying cylinder 2. The carbon fiber precursor is close to the drying cylinder 2. The drying cylinder 2 rotates continuously, driving the carbon fiber precursor to move. After drying, the carbon fiber precursor is pulled to the lower side of the second roller 9. As the second roller 9 rotates, the carbon fiber precursor pulled out from the lower side of the second roller 9 is pulled to the upper side of the third roller 3. As the second roller 9 and the third roller 3 rotate, the dried carbon fiber precursor is pulled out. Under the action of the flow splitting mechanism 1, the direction of the carbon fiber precursor remains unchanged during the drying process, and it is evenly heated when passing through the drying cylinder 2, improving the drying efficiency and the overall quality of the carbon fiber precursor.
