Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber precursor processing, and specifically relates to a loading device for carbon fiber precursors. Background Technique

[0002] Carbon fiber precursor is the basic raw material for manufacturing carbon fiber composites, mainly made of polyacrylonitrile (PAN). In the production process, first, polyacrylonitrile is made into slender fibers through a spinning process, and then through an oxidation and carbonization process, it is transformed into carbon fiber. Carbon fiber has excellent properties such as high strength, high modulus, and low density, and is widely used in fields such as aerospace, automotive, and sports equipment. The quality of carbon fiber precursor directly affects the performance of the final carbon fiber product. The processing process of carbon fiber precursor includes the selection of raw materials to the transformation of the final product form, involving precise control of multiple links, aiming to ensure the excellent properties and quality stability of carbon fiber. Therefore, in the production process, it is necessary to strictly control the selection of raw materials, spinning process parameters, and subsequent chemical treatment processes to ensure the uniformity and stability of the precursor.

[0003] During the processing of carbon fiber precursor, it is necessary to load it, so a loading device is required. Although the traditional loading device has the loading capacity, it still has some deficiencies. For example, it is difficult to tighten the carbon fiber precursor after winding and loading, so the carbon fiber precursor will be loose during winding and loading, which will affect the processing effect of subsequent processes. In addition, its anti - detachment ability after winding and loading the carbon fiber precursor is not good, so it is easy to cause the carbon fiber precursor loaded by winding to slip and unwind, thus affecting its winding and loading effect. Therefore, a loading device for carbon fiber precursor is proposed to solve the above problems. Content of the Utility Model

[0022] A loading device for carbon fiber precursor filaments, comprising a base 1. On both sides of the top of the base 1, support frames 2 are symmetrically and fixedly connected. A loading roller 3 is arranged between the support frames 2, and both ends of the loading roller 3 are rotatably connected to the inner side walls of the adjacent support frames 2. A first motor 4 is fixedly connected to the outer side wall of one support frame 2, and the output end of the first motor 4 penetrates through this support frame 2 and is fixedly connected to the central axis of the loading roller 3. Limiting baffles 5 are symmetrically and movably sleeved at both ends of the loading roller 3. Adjusting components 6 are symmetrically arranged on the front and rear sides of the limiting baffles 5. An anti-disengagement component 7 is arranged at the center of the base 1.

[0023] The adjusting assembly 6 includes a second motor 601 fixedly connected to the support frame 2 through a connecting short rod. On one side wall of the two second motors 601 close to each other, an adjusting groove 602 is fixedly connected. A threaded rod 603 is fixedly connected to the output end of the second motor 601. One end of the threaded rod 603 away from the second motor 601 penetrates the side wall of the adjusting groove 602 and is rotatably connected to the inner wall on the other side of the adjusting groove 602. A threaded seat 604 penetrates and is threadedly connected to the threaded rod 603. The threaded seat 604 is slidably connected to the adjusting groove 602. One end of the threaded seat 604 close to the load-carrying roller 3 is fixedly connected with an adjusting connecting rod 605. A through groove is formed on one side wall of the adjusting groove 602 close to the load-carrying roller 3, and the adjusting connecting rod 605 extends out of the adjusting groove 602 through the through groove and is fixedly connected with the limit baffle 5. The adjusting assembly 6 can provide a driving force for the movement of the limit baffle 5, so as to drive the limit baffle 5 to tighten the carbon fiber roving after winding and loading, so as to avoid the situation of loose winding of the carbon fiber roving during winding and loading, and thus ensure the processing effect of subsequent processes; the anti-detachment assembly 7 includes an anti-detachment cavity 701 opened at the center of the inner cavity of the base 1. An electric push rod 702 is fixedly connected to the bottom of the inner cavity of the anti-detachment cavity 701. The output end of the electric push rod 702 penetrates the top wall of the base 1 and extends above the base 1. An anti-detachment support plate 703 is fixedly connected to the end of the output end of the electric push rod 702. The anti-detachment support plate 703 is arc-shaped and is arranged corresponding to the load-carrying roller 3. The anti-detachment assembly 7 can perform anti-detachment treatment on the carbon fiber roving after winding and loading, so it is not easy to cause the carbon fiber roving wound and loaded to slide and unwind, thus ensuring its winding and loading effect.

[0024] Workflow: First, power on all electrical appliances. The support frame 2 can support the load roller 3 and enable the load roller 3 to rotate and wind. The first motor 4 can provide driving force for the load roller 3 to enable it to rotate, so as to wind and support the carbon fiber roving. The limit baffle 5 can tighten the carbon fiber roving after winding and supporting, thus avoiding the situation of loose winding when the carbon fiber roving is wound and supported, and ensuring the processing effect of subsequent processes. The adjustment component 6 can provide driving force for the movement of the limit baffle 5, so as to drive the limit baffle 5 to tighten the carbon fiber roving after winding and supporting. When the carbon fiber roving is wound and supported, start the second motor 601. The second motor 601 can drive the threaded rod 603 to rotate, so as to drive the threaded seat 604 to move in the adjustment groove 602. The movement of the adjustment seat will drive the connected limit baffle 5 to approach each other through the adjustment link 605 on it, so as to tighten the carbon fiber roving through the limit baffle 5. The anti-loosening component 7 can prevent the carbon fiber roving after winding and supporting from loosening, so it is not easy to cause the carbon fiber roving wound and supported to slide and unwind, thus ensuring its winding and supporting effect. By controlling the extension of the electric push rod 702, the anti-loosening support plate 703 on it can be driven to move upward. When the anti-loosening support plate 703 moves upward to fit and press against the lower surface of the carbon fiber roving, it is okay. At this time, the tight pressing of the carbon fiber roving by the anti-loosening support plate 703 can prevent the load roller 3 from rotating due to other factors and causing the carbon fiber roving to unwind.
