[0001] The present invention relates to the technical field of carbon fiber preparation, and specifically to an air shower device for the surface of carbon fiber. Background Art

[0002] Polyacrylonitrile-based carbon fiber reinforced fiber is the main material of composite materials. High-efficiency and low-cost carbon fiber is of great significance to the lightweight of composite materials. Polyacrylonitrile fiber (raw silk) is the main raw material for preparing large tow carbon fiber; large tow carbon fiber has the advantage of low cost compared with small tow fiber. Large tow carbon fiber is more conducive to developing into low-cost and general-purpose fiber; according to the market situation, it is important to improve the production operation speed and increase the production output.

[0003] However, currently, carbon fiber needs to go through multiple processes to be prepared. In the carbon fiber drying process, after the surface treatment of carbon fiber through non-contact drying and hot roll drying, its surface will be uneven and there will be large hair filaments on the surface, which will affect the overall quality of carbon fiber. Now, an air shower device for the surface of carbon fiber is designed to remove the hair filaments. Summary of the Invention

[0013] Beneficial effects

[0014] The present invention provides a carbon fiber surface air shower device. Compared with the existing technology, the following beneficial effects are achieved:

[0015] (1). In this carbon fiber surface air shower device, by arranging two upper and lower air guide pipes between the two side linkage support frames, and connecting a plurality of jet blocks through air guide pipes at the front part of the air guide pipes, and a V-shaped air outlet and a flat groove are formed at the front part of the jet block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6 , the present invention provides a technical solution: a carbon fiber surface air shower device, including a bottom plate 1. Both sides of the top of the bottom plate 1 are fixedly connected with linkage support frames 2 through fixing plates. A reinforcing top plate 3 is fixedly connected between the tops of the two linkage support frames 2 through a fixing block. The tops of the inner cavities of the two linkage support frames 2 are both rotatably connected with threaded rods 4 through bearing members. The lower part of the surface of the left threaded rod 4 and the upper part of the surface of the right threaded rod 4 are both threadedly connected with threaded cylinders 5. Both sides of the two threaded cylinders 5 close to each other are fixedly connected with air guide pipes 6 through fixing blocks. One end of the air guide pipe 6 away from the threaded cylinder 5 penetrates through the linkage support frame 2 and extends to the outside of the linkage support frame 2. The upper and lower parts of the right side of the right linkage support frame 2 are both fixedly connected with superchargers 7. The air outlet of the supercharger 7 is fixedly connected with a diversion pipe 8. One ends of the two diversion pipes 8 are respectively fixedly communicated with the rear parts of the adjacent air guide pipes 6.

[0027] As an optional embodiment, in order to be able to guide the high-pressure air flow to be sprayed in a fan shape to blow off the filaments, both sides of the surface of the air guide pipe 6 are fixedly connected with extension plates 9. A rotating rod 10 is rotatably connected between the two extension plates 9 through a bearing member. A jet block 11 is fixedly connected to the surface of the rotating rod 10, and a plurality of jet blocks 11 are equidistantly arranged. An air guiding pipe 12 is fixedly communicated between the rear part of the jet block 11 and the air guide pipe 6. A V-shaped air outlet 13 is formed on the surface of the jet block 11, and a flat groove 14 matching the air guiding pipe 12 is formed at the rear part inside the V-shaped air outlet 13.

[0028] Furthermore, in order to be able to synchronously adjust the angles of a plurality of jet blocks 11, the left end of the rotating rod 10 penetrates through the extension plate 9 and extends to the left side of the extension plate 9. One end of the rotating rod 10 extending to the left side of the extension plate 9 is fixedly connected with a worm gear 15 through a fixing block. A worm 16 meshing with the worm gear 15 is rotatably connected to the rear part of the left side of the left extension plate 9 through a bearing member. A screwing piece 17 is fixedly connected to the bottom end of the worm 16.

[0029] Among them, in order to ensure the stability of the lifting of the air duct 6, moving ports 18 adapted to the air duct 6 are provided on the opposite sides of the two linkage support frames 2. The lower part of the surface of the threaded rod 4 is rotatably connected to a bearing cylinder 19. The front and rear parts of the bearing cylinder 19 are fixedly connected to the inside of the linkage support frame 2 through connecting rods 20. Slide groove plates 24 are fixedly connected to the farther sides of the inner cavities of the two linkage support frames 2 through fixing plates. A slider 25 is slidably installed inside the slide groove plate 24. A limiting rod 26 is fixedly connected between one side of the slider 25 and the adjacent bearing cylinder 19.

[0030] Among them, in order to facilitate the staff to individually adjust the height of the air duct 6, the bottom end of the threaded rod 4 is fixedly connected with a second bevel gear 23 through a fixing block. A driven rod 21 is rotatably connected to the lower part of the rear of the inner cavity of the linkage support frame 2 through a bearing member. A first bevel gear 22 meshing with the second bevel gear 23 is fixedly connected to the surface of the driven rod 21. The front end of the driven rod 21 penetrates through the linkage support frame 2 and extends to the front of the linkage support frame 2. One end of the driven rod 21 extending to the front of the linkage support frame 2 is fixedly connected with a rotating disk 27 through a fixing block.

[0031] Meanwhile, the content not detailedly described in this specification all belongs to the prior art well-known to those skilled in the art.

[0032] During use, the staff transports the equipment to the carbon fiber preparation line and places it at the rear of the drying process equipment. Then the staff adjusts the distance and height between the upper and lower air ducts 6 according to the height of the limiting belt. First, manually rotate the rotating disk 27 to make the driven rod 21 drive the first bevel gear 22 to rotate. Due to the meshing of the second bevel gear 23 and the first bevel gear 22, the threaded rod 4 can be rotated, enabling the threaded cylinder 5 to drive the air duct 6 to lift under the limitation of the slide groove plate 24. When the height and distance between the two air ducts 6 are adjusted, then adjust the air outlet angles of several jet blocks 11. The staff manually turns the turning piece 17 to make the worm 16 drive the worm wheel 15 to rotate. When the worm wheel 15 rotates, it will drive several jet blocks 11 to rotate through the rotating rod 10, making the V-shaped air outlets 13 on the upper and lower sides tilt relatively and align with the upper and lower parts of the fiber belt. Then it can be used. During the preparation process, the fiber belt moves out from the drying roller. At this time, after the fiber bag passes through high temperature, the surface drying degree is uneven, resulting in relatively large surface fuzz. Then start the two superchargers 7, introduce the air flow into the inside of the air duct 6 through the diversion pipe 8. The V-shaped air outlets 13 on the surface of the jet block 11 and the flat grooves 14 opened inside can form a fan shape with the gas and blow out to blow the fuzz on the surface of the fiber belt.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
