Carbon fiber sizing equipment and control method

The invention discloses carbon fiber sizing equipment which comprises a sizing device for sizing carbon fibers, an overflow device for preventing sizing liquid in the sizing device from overflowing, a liquid supplementing device for supplementing lost sizing liquid for the sizing device and a control system matched with the sizing equipment, and the sizing device comprises a sizing tank for storing the sizing liquid. The fiber passing roller set is used for guiding carbon fibers to be soaked in the sizing liquid, the stirring mechanism is used for scraping sediments at the bottom of the sizing tank, and the stirring mechanism comprises a sliding rail stretching across the upper portion of the sizing tank and a scraping plate in sliding fit with the sliding rail. The invention further discloses a control method for the carbon fiber sizing equipment. The carbon fiber equipment disclosed by the invention can ensure that the concentration of sizing liquid in the size tank is uniform, so that the sizing liquid can
