Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber sizing devices, in particular to an industrialized carbon fiber sizing device. Background Art

[0002] Sizing is the last step in the carbon fiber process before it is dried and rolled into finished carbon fiber products after surface treatment. Sizing is used to bundle the carbon fibers, similar to an adhesive that holds them together, improving their processing properties. On the one hand, the sizing layer makes the carbon fibers easier to process, and on the other hand, it protects them by reducing friction damage between them and by reducing friction damage caused by rollers during subsequent processing (such as pultrusion or weaving).

[0003] During the sizing process of the carbon fiber bundles, dust is attached to the surface of the carbon fiber bundles during transportation. During the sizing process, the sizing agent will solidify the dust and impurities on the carbon fiber bundles, affecting the quality of the protective film. Utility Model Content

The sizing box 1 is detachably connected to a mounting plate 8 on the side close to the introduction roller 4, and a lower fixed plate 9 is fixedly connected to the top of the mounting plate 8. An arc-shaped lower cleaning groove 10 is evenly opened on the top of the lower fixed plate 9, and an upper fixed plate 12 is connected to the side close to the derivation roller 6 by a connecting rod 11. The bottom of the upper fixed plate 12 is evenly opened with an arc-shaped upper cleaning groove 13.

[0019] The inner walls of the lower cleaning tank 10 and the upper cleaning tank 13 are provided with cleaning sponges or cleaning brushes. A dust hood connected to a vacuum cleaner can be installed on the side of the sizing box 1 close to the mounting plate 8 to suck away dust and other debris removed from the surface of the carbon fiber bundle.

[0020] The carbon fiber bundle passes through the lower cleaning tank 10 and the upper cleaning tank 13 and is introduced into the sizing tank 2 by the introduction roller 4.
