Description

[0002] Pre-oxygenation treatment of clothing fibers is a process used to improve fiber properties. When preparing high-performance fibers such as carbon fibers, this process usually includes heating the fibers to a certain temperature to partially oxidize them, thereby forming a stable structure and preparing for the subsequent carbonization process.

[0003] In the process of continuous pre-oxygenation of clothing fibers, in order to fully pre-oxygenate the two surfaces of the clothing fibers at different positions, it is usually necessary to add a long-distance processing production line or wind the clothing fibers in a pre-oxygenation box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention places the fiber felt in a pre-oxygenation box through a material guide box, so that the fiber felt is wound around multiple guide components, a driving component, a primary electric heating roller, a secondary electric heating roller and a tertiary electric heating roller, and both ends of the fiber felt extend outside the material guide box. When the fiber felt is pre-oxygenated, the hot air blower is controlled to work and the hot air is discharged from the air outlet through the air duct. Because the air outlet is evenly arranged outside the air duct, the fiber felt can be heated and pre-oxygenated in all directions. At the same time, the air outlet end of the hot air blower can introduce the hot air into the air duct through the connecting pipe, so that the hot air is sprayed from the exhaust nozzle in the air duct to the other side of the fiber felt, and the air outlet is evenly arranged in the air duct to further improve the uniformity of pre-oxygenation of the fiber felt.

[0019] The present invention assists in guiding the fiber felt through a plurality of driving rollers, thereby reducing the friction generated during the transmission of the fiber felt. When the fiber felt moves on the guide roller, the guide roller will squeeze the slider after being compressed, so that the slider can slide in the slideway, and the slider is reversely supported by the elastic force of the spring, which plays a role in supporting and buffering the guide roller, thereby preventing the fiber felt from being torn off. When the fiber felt becomes loose, the elastic force of the spring can support the guide roller through the slider, so that the plurality of guide rollers can tighten the fiber felt to prevent the loose fiber felt from affecting its normal transmission. Because the guide rollers and the driving rollers are staggered, the fiber felt is partially divided into triangular partitions, and the heating surface of the fiber felt can be continuously switched during the guiding process of the fiber felt, without the need to add a long-distance processing production line, thereby improving energy efficiency and reducing use costs.

[0020] 3. The present invention allows the fiber felt to pass through a material guide box so that the fiber felt is located between the pressure roller and the support roller. The screw can move in the nut during the rotation of the lead screw, so that the lead screw drives the pressure roller to move through the connecting bearing until the fiber felt can be clamped by the support roller and the pressure roller, thereby facilitating the positioning of fiber felts of different thicknesses. The fiber felt can drive the support roller and the pressure roller to rotate during its movement, ensuring that the fiber felt is in a horizontal moving state in the material guide box, thereby smoothing the fiber felt and preventing wrinkles on the fiber felt that affect the pre-oxidation effect. The two guide wheels at the opening of the material guide box can guide the fiber felt, so as to facilitate the unwinding and winding of the fiber felt at different positions.

After being compressed, the guide roller 301 will squeeze the slider 303 and the spring 304. The elastic force of the spring 304 supports the slider 303 and the guide roller 301, thereby buffering the fiber felt 2 and preventing the fiber felt 2 from being torn off.

[0041] During operation, the motor 502 can drive the driving roller 503 to rotate through the transmission wheel 501. Since the three transmission wheels 501 are connected by the transmission belt 504, the three driving rollers 503 can rotate synchronously, so that the driving roller 503 can assist in guiding the fiber felt 2, thereby reducing the friction of the fiber felt 2 during transmission.

The air outlet end of the hot air blower 901 is connected to a wind tube 903, and the wind tube 903 is installed in the pre-oxygenation box 1. The outer wall of the wind tube 903 is provided with a plurality of air outlets 904, and the wind tube 903 is located in the middle of the pre-oxygenation box 1.

[0045] When working, the hot air blower 901 can guide the hot air into the air duct 903, and the air duct 903 can evenly discharge the hot air from the air outlet 904, so as to achieve the purpose of evenly heating and pre-oxidizing the surface of the fiber felt 2.

[0046] As a further solution of the present invention, the air outlet end of the hot air blower 901 is connected to five connecting pipes 905, and the other end of the connecting pipe 905 is connected to an air duct 906, which is installed in the pre-oxygenation box 1. The air duct 906 is fan-shaped and has a plurality of exhaust nozzles 907 on the inner wall, and the five air ducts 906 are respectively located at the edges of the pre-oxygenation box 1.

[0047] During operation, since the air ducts 906 are evenly arranged in the pre-oxidation box 1, the fiber felt 2 can be heated and pre-oxidized in an azimuth manner to improve the uniformity of pre-oxidation.

[0048] As a further solution of the present invention, two guide wheels 11 are installed on one side of the material guide box 10 , and the fiber mat 2 is overlapped on the two guide wheels 11 . The guide wheels 11 are located at the opening edge of the material guide box 10 .

[0049] During operation, the fiber felt 2 can move on the guide wheel 11, which reduces the friction of the fiber felt 2 while facilitating the winding or unwinding of the fiber felt 2 at different positions.

[0050] As a further solution of the present invention, the material supporting assembly 12 includes a fixed frame 121, which is installed in the material guide box 10. A support roller 122 is installed in the fixed frame 121. The support roller 122 overlaps the fiber felt 2 and is located between the two limiting assemblies 13.

[0051] During operation, the fiber mat 2 is brought into contact with the support roller 122 during its movement, preventing the fiber mat 2 from directly contacting the inner wall of the pre-guide box 10, thereby increasing friction and improving the stability of the transportation of the fiber mat 2.

The nut 133 is clamped on the material guide box 10, and the two sides of the pressure roller 131 are respectively fixedly connected to the limiting columns 14, and the limiting columns 14 are arranged through the material guide box 10.

[0053] During operation, when adjusting the height of the pressing roller 131, the screw rod 134 is rotated to drive the pressing roller 131 to move, so that the pressing roller 131 and the supporting roller 122 can limit the fiber felt 2, which is convenient for guiding and conveying the fiber felt 2 of different thicknesses, and can also flatten the fiber felt 2 to improve the subsequent pre-oxygenation effect.

[0056] Working principle of the present invention: During operation, the fiber mat 2 is placed in the pre-oxidation box 1 through the material guide box 10, and the fiber mat 2 is wound around a plurality of guide rollers 301, a driving roller 503, a primary electric heating roller 6, a secondary electric heating roller 7 and a tertiary electric heating roller 8, and both ends of the fiber mat 2 extend outside the material guide box 10, and the fiber mat 2 is located between the pressing roller 131 and the supporting roller 122. During the process of rotating the screw rod 134, the screw rod 134 is able to move in the nut 133, so that the screw rod 134 drives the pressing roller 131 to move through the connecting bearing 132 until the fiber mat 2 is The felt 2 can be clamped by the support roller 122 and the pressure roller 131. During the movement of the fiber felt 2, the support roller 122 and the pressure roller 131 can be driven to rotate, ensuring that the fiber felt 2 is in a horizontal moving state in the material guide box 10, and the two guide wheels 11 at the opening of the material guide box 10 can guide the fiber felt 2, and one end of the fiber felt 2 is connected to the winding mechanism for winding. When the fiber felt 2 is pre-oxidized, the hot air blower 901 is controlled to work, and the hot air is discharged from the air outlet 904 through the air duct 903, so that the fiber felt 2 can be pre-oxidized in multiple directions. The fiber felt 2 is heated and pre-oxidized, and the hot air is introduced into the air duct 906 through the connecting pipe 905, so that the hot air is sprayed from the exhaust nozzle 907 in the air duct 906 to the other side of the fiber felt 2, and the exhaust nozzles 907 are evenly arranged in the air duct 906 to further improve the uniformity of pre-oxidation of the fiber felt 2. By adjusting the temperature of the first-level electric heating roller 6, the second-level electric heating roller 7 and the third-level electric heating roller 8, different heat can be divided into different zones. When the fiber felt 2 moves on the guide roller 301, the guide roller 301 will squeeze the slider 303 after being pressed, so that the slider 303 can slide on the slide. The fiber felt 2 slides in the guide path 4, and the elastic force of the spring 304 supports the slider 303 in the reverse direction, so as to buffer the fiber felt 2 on the guide roller 301. When the fiber felt 2 becomes loose, the elastic force of the spring 304 can support the guide roller 301 through the slider 303, so that the multiple guide rollers 301 can tighten the fiber felt 2. The guide roller 301 and the driving roller 503 can support and guide the fiber felt 2, so that the fiber felt 2 forms a triangular partition locally, and the heating surface of the fiber felt 2 can be continuously switched for pre-oxygenation treatment.
