Refer to chinese patent publication No. CN 102767054A's a carbon fiber rinsing machine, through the rotation of upper and lower driving roller, drive upper and lower driving roller through chain and drive mechanism and rotate in step, prolonged the cleaning time of carbon fiber, improved the cleaning quality of carbon fiber, and drive upper and lower driving roller through this drive mechanism and rotate in step, avoid because the carbon fiber fracture or the carbon fiber that upper and lower driving roller transmission is asynchronous and cause and mix together, not only can improve the cleaning efficiency through a plurality of drive roller sets.

Referring to the carbon fiber sizing device and method disclosed in chinese patent publication No. CN109183310B, the sizing agent moves from the sizing tank to the overflow tank under the action of the circulation mechanism, and the sizing agent in the overflow tank flows downward into the sizing tank along the counter-flow tank under the action of gravity, so as to form a continuous flowing sizing agent circulation. The filament bundle is connected with the transmission mechanism, flows upwards along the counter-current groove after passing through the sizing groove under the action of the transmission mechanism, the moving direction of the filament bundle is opposite to the flowing direction of sizing liquid, the sizing liquid can penetrate through the surface of the filament bundle to be contacted with monofilaments in the filament bundle under the action of impact force, the filament bundle is fully infiltrated, the contact between the filament bundle and the sizing liquid is more sufficient, and sizing is more uniform.

A comprehensive analysis of the above referenced patents can yield the following drawbacks:

1) the existing carbon fiber production equipment can only realize independent washing and sizing treatment of carbon fibers, cannot realize simultaneous treatment by combining washing and sizing treatment procedures, cannot achieve the aim of conveniently and efficiently carrying out washing and sizing treatment of the carbon fibers, greatly reduces the production efficiency, increases the workload of production personnel, for example, refer to patent CN107385735B for a system for water washing drying, sizing and drying and sizing of carbon fibers, although the patent combines three procedures of water washing, drying and sizing, the adoption of a long production line still occupies more space, and the widening of the line width is realized by adopting a large number of rollers, the cost is higher, the parallel design can not be realized to save more space, and the design of winding at the bottom of the washing tank is adopted to reduce the washing cost, thereby bringing great inconvenience to the use of people.

2) The existing carbon fiber washing equipment can only singly realize the soaking and cleaning of electrolyte on the surface and impurities with small adhesive capacity, for example, refer to a carbon fiber washing machine of patent CN102767054A, the cleaning quality is improved only by adopting a plurality of rollers to wind and prolong the soaking time, the cleaning effect is still not good, and impurities with large adhesive force on the surface of the carbon fiber cannot be sufficiently cleaned, thereby seriously affecting the production quality of the carbon fiber.

3) Although the existing carbon fiber sizing device and method in patent CN109183310B adopt an inclined runoff dipping method to enable the slurry on the fiber surface to be uniformly dipped, the inclined design still needs to overcome the problem that the slurry is downwardly gathered into drops under the action of self gravity, and the slurry which is just adhered to the fiber surface is rubbed and peeled by a roller directly guided by the roller after dipping, resulting in sizing failure, and the common dipping and vertical line-taking design cannot be adopted to enable the slurry on the fiber to flow uniformly on the fiber surface to ensure uniform sizing, so that the purpose of rapid and efficient sizing cannot be achieved, thereby being very disadvantageous for carbon fiber production enterprises.
