Technical Field
[0001] This utility model relates to the field of carbon fiber processing technology, specifically to an electric heating drying device for carbon fiber processing. Background Technology
[0002] Carbon fiber, as a high-strength and lightweight new material, has a wide range of applications in aerospace, automobile manufacturing, and sporting goods. Its excellent performance largely depends on every step of the processing, among which drying is particularly critical. During the production and processing of carbon fiber, it inevitably absorbs a certain amount of moisture. If this moisture is not completely removed, it will seriously affect the subsequent impregnation and curing processes of carbon fiber, leading to defects such as bubbles and delamination in the finished product, and significantly reducing the mechanical properties and service life of the product.
[0003] Chinese Patent No. CN219829288U discloses a microwave dryer for processing carbon fiber felt. This utility model, by setting up a drying box and fixing strips, facilitates the placement of carbon fiber felt rolls. The carbon fiber felt rolls are sleeved on the connecting shaft, and the connecting shaft is squarely placed inside the drying box. At the same time, the two ends of the connection are respectively located in the limiting grooves on the fixing strips, and the carbon fiber felt rolls are supported by the fixing strips.
[0004] However, the microwave dryer used for processing carbon fiber felt mentioned in the above scheme attaches the carbon fiber felt roll to the connecting shaft. The connecting shaft cannot rotate, and the statically fixed carbon fiber will not change its posture, resulting in uneven heating and uneven drying.
[0005] Therefore, it is necessary to invent an electrically heated drying device for carbon fiber processing. Utility Model Content

A scraper 296 is fixed at the top of the vertical plate 295. An arc-shaped filter screen 11 is fixed on the top of the heating box 1. A horizontal plate 22 is fixed between the two side walls of the rectangular frame 21. The outer wall of the double-headed threaded rod 23 is provided with threaded grooves with opposite ends to facilitate the rack 1 25 and rack 298 to move in opposite directions or towards each other.
[0021] Furthermore, the top of the heating box 1 is provided with an exhaust groove 111, and the arc-shaped filter screen 11 is fixedly installed in the exhaust groove 111.
[0022] Furthermore, fans 18 are provided on both sides of the heating box 1, and multiple electric heating tubes 19 are fixed between the top and bottom of both sides of the heating box 1. The double-headed threaded rod 23 passes through one of the rectangular plates 211 and a column 24 is fixed at its end to facilitate the rotation of the double-headed threaded rod 23.
[0023] Furthermore, a circular shaft 171 is fixedly provided on both sides of the rectangular frame 21, and the circular shaft 171 is rotatably connected to the inner wall of the heating box 1 to facilitate the rotation of the rectangular frame 21.
[0024] Furthermore, a motor 17 is fixedly installed on one side of the outer wall of the heating box 1. The output shaft of the motor 17 passes through the heating box 1 and is fixedly connected to the round shaft 171 to facilitate the rotation of the round shaft 171.
[0025] Furthermore, a through groove 132 is provided on one side of the heating box 1, and symmetrically distributed fixing plates 12 are fixedly provided on one side of the heating box 1. A box door 13 is rotatably provided between the two fixing plates 12, and a rectangular frame sealing gasket 131 is fixedly provided on one side of the box door 13 for easy sealing.
[0026] Furthermore, a block 15 is fixedly provided on one side of the heating box 1, and a screw 16 is threaded into the top of the block 15. A connecting block 14 is fixedly provided at one end of the box door 13, and the screw 16 is movably inserted into the connecting block 14 to facilitate fixing the box door 13.
[0027] Furthermore, a circular groove 141 is provided on the top of the connecting block 14, and the screw 16 is movably inserted into the circular groove 141 to facilitate the positioning of the connecting block 14.
[0028] Furthermore, symmetrically distributed springs 29 are fixedly provided on the side of the C-shaped plate 28 and the C-shaped plate 293 that are close to each other, and a pressure plate 291 is fixedly provided on the other end of the spring 29.
[0029] Working principle: When using this solution for carbon fiber drying, first open the box door 13 and place the carbon fiber material to be dried on the horizontal plate 22 inside the rectangular frame 21. Then rotate the column 24, which in turn drives the double-headed threaded rod 23 to rotate. This causes the rack 1 25 and rack 2 298 to move in opposite directions, which in turn drives the gear 1 27 and gear 2 294 to rotate. This causes the C-shaped plate 1 28 and C-shaped plate 2 293 to flip towards the carbon fiber at the same time. When the C-shaped plate 1 28 and C-shaped plate 2 293 are in contact with both sides of the carbon fiber, the pressure plate 291 tightly clamps the carbon fiber under the elastic force of the spring 29, thus achieving a stable fixation of the material and preventing the drying process from being affected by shaking. After fixing, close the box door 13 and lock it with the screw 16 and the connecting block 14. The rectangular frame sealing gasket 131 ensures the airtightness of the heating box 1. Start the electric heating tube 19 and the fan 18. The electric heating tube 19 releases heat to raise the temperature inside the heating box 1. The fan 18 accelerates the air circulation inside the box, so that the hot airflow acts evenly on the carbon fiber surface. The moisture in the material is quickly evaporated through heat transfer to achieve the drying process. During this process, motor 17 can be started at the same time. The output shaft of motor 17 drives the round shaft 171 to rotate, thereby causing the rectangular frame 21 to rotate as a whole in the heating box 1, which in turn drives the clamped carbon fiber to rotate, ensuring that all parts of the material can fully contact the hot airflow and improve the drying uniformity. The moisture generated during the drying process is discharged through the top exhaust slot 111. The arc-shaped filter 11 can filter impurities in the air and prevent external pollutants from entering the heating box 1 and contaminating the carbon fiber. When the C-shaped plate 293 flips towards the carbon fiber, it drives the vertical plate 295 and scraper 296 to rotate. The rotation of the scraper 296 can scrape the surface of the arc-shaped filter screen 11 to remove the attached dust and impurities, ensure smooth exhaust, and maintain the heat circulation efficiency inside the heating box 1.
