Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber processing, in particular to a carbon fiber pre-oxidation processing device. Background Art

[0002] Carbon fiber pre-oxidation is a very complex process that requires fine control. In this process, the carbon fiber needs to be heated and oxygen or oxygen-containing gas is introduced within a specific temperature range. However, to achieve the ideal pre-oxidation effect, it is far more than that. It is also necessary to accurately control many parameters such as temperature, oxygen concentration, ventilation rate, processing time, and fiber tension.

[0003] Temperature control must be precise and stable, only in this way can the reaction be carried out evenly. The oxygen concentration and ventilation rate will significantly affect the speed and degree of the oxidation reaction. The length of the treatment time also plays a key role in the effectiveness of pre-oxidation. If the time is too short, it may lead to incomplete oxidation; if the time is too long, it may have an adverse effect on the performance of the fiber. At the same time, applying appropriate tension to the fiber helps to maintain the uniformity of the fiber's morphology and structure.

[0004] The Chinese patent with the announcement number "CN215668317U" discloses a carbon fiber pre-oxidation processing device, which includes a bottom plate, a pre-oxidation processing device, an oxygen inlet pipe, a regulating valve, an outer shell, a feed port, a discharge port, a guide wheel, an insulating bottom plate, an electric heater assembly, an electric heating plate and a cooling device. The above device has a simple structure and is easy to use. It can effectively increase the effect of carbon fiber line pre-oxidation and has a good heating effect. At the same time, the oxygen content in the outer shell can be adjusted as needed to ensure its sufficient pre-oxidation;

[0005] However, although the above-mentioned device can achieve a certain degree of heating pre-oxidation effect during specific application, there are still some defects that cannot be ignored during actual use. First, there is a lack of tension adjustment structure inside the oxidation equipment. During use, the tension of the carbon fiber cannot be adjusted according to specific oxidation requirements. This makes it very easy for the carbon fiber to become loose during the entire use process, and thus it cannot be in contact with oxygen more evenly and stably. Moreover, during the oxidation process, the overall heating method can only be used for single-sided heating, and the oxygen is also introduced from one side. This single-sided heating mode will make it difficult to heat the top of the carbon fiber evenly, and the method of introducing oxygen from one side will cause the oxygen to not evenly cover the carbon fiber, which is very likely to cause uneven oxidation problems. Overall, the device has certain defects and deficiencies in overall use and processing, and it is necessary to improve it. Summary of the invention

[0035] See also Figure 1-Figure 5 and Figure 8The cooling mechanism 7 includes a cooling box 71, which is fixedly mounted on one side of the bottom of the oxidation box 5.

The entire cooling process is efficient, energy-saving, stable and reliable.

[0036] The working principle of the present invention is: by setting up the oxygen supply mechanism 3, the device can be connected to the external oxygen supply pipeline by means of the connecting flange 33 during actual application. At this time, oxygen can be transported to the inside of the oxygen external connecting pipe 31 rack through the oxygen external connecting pipe 31, and then through the auxiliary guidance of the oxygen pipe rack 32, the oxygen is evenly discharged to the top and bottom of the oxidation box 5 through the oxygen discharge pipe 34. In this way, the oxygen can be evenly filled in the oxidation box 5, so that the oxygen can react evenly with the carbon fiber, thereby improving the stability and uniformity of the overall reaction processing of the equipment. In addition, during its use, the heater assembly 10 is arranged at the top and bottom of the oxidation box 5. When the electric heating wire 103 inside the mounting groove 102 on the mounting seat 101 is running, it can promote the oxidation The top and bottom of the box 5 are used to heat the carbon fiber uniformly, so that the oxygen and heat distribution on the surface of the carbon fiber is relatively uniform, thereby improving the stability of the pre-oxidation of the overall production and processing of the device. Moreover, during the production and processing, when the carbon fiber is discharged from the oxidation box 5, the carbon fiber can be wound around the outer surface of the guide roller 73 inside the cooling box 71, and then pass through the scraper 74. When the carbon fiber passes through the scraper 74, the scraper 74 can scrape off the water, and the setting of the guide roller 73 can allow the carbon fiber to be immersed in the cooling water, thereby achieving a good cooling effect and preventing the carbon fiber from scalding the human body. In addition, during the cooling period, by starting the operation of the semiconductor refrigerator 75, the coolant inside the cooling box 71 can be cooled by the operation of the semiconductor refrigerator 75, which can enhance the convenience of the overall use of the device.

[0037] By setting the tensioning mechanism 6, the device can pass the carbon fiber through the tensioning tube 635 of the tensioning frame 634 during use, and the adjusting wheel 614 can be driven to rotate by pulling the handrail crank 615. The rotation of the adjusting wheel 614 can drive the transmission worm 613 to rotate. Since the transmission worm 613 and the transmission worm wheel 612 are connected in transmission, the transmission worm 613 can drive the transmission worm wheel 612 to rotate. The rotation of the transmission worm wheel 612 can drive the turntable 631 to rotate. At the beginning of the rotation of the turntable 631, the tensioning frame 634 and the tensioning tube 635 can be driven to rotate. At this time, the carbon fiber will be connected to the outer surface of the tensioning tube 635. As the tensioning frame 634 rotates, the carbon fiber can be tightened. As the handrail crank 615 is continuously pulled, the tension torsion spring 632 will be tightened. When the tension torsion spring 632 is tightened, its elastic force will increase, and the corresponding The elastic force of the tension torsion spring 632 acts on the carbon fiber, so that the carbon fiber can be better tightened. By adjusting and pulling the armrest crank 615 to drive the transmission worm 613 further, and adjusting the amplitude of the rotation of the adjusting wheel 614 driven by the armrest crank 615, the overall elastic force of the tension torsion spring 632 can be increased. The increase in its elastic force can enhance the tensioning force on the carbon fiber, so that the device as a whole can quickly adjust the tension inside the oxidation box 5 according to the production and processing requirements, which can improve the overall production and processing quality of the equipment. After the tension adjustment is completed, it is only necessary to twist the adjusting screw 616 and insert it into the inner side of the limiting hole at the corresponding position. At this time, the adjusting wheel 614 can be locked and fixed. This makes it easy to quickly adjust the tension of the device as a whole, and it can be quickly locked and fixed, which can improve the stability of the device as a whole for carbon fiber production and processing.
