The utility model relates to a glue applying device of papermaking equipment. The device is including the sizing applicator that is arranged in papermaking device fabrication line, the inlet line that the sizing agent entry of sizing applicator is connected connects AKD liquid storage tank and top sizing liquid storage tank through measuring pump and glue solution pump respectively, return line lug connection is crossed extremely to the sizing agent backward flow antilinear of sizing applicator inlet line. The utility model discloses a device makes papermaking glueing in -process, and AKD after the AKD direct glueing in surface does not directly flow back among the adhesive solution tank, but directly the flow back inlet line of sizing applicator has effectively reduced the dwell time of AKD in high -temperature glue liquid to reduce AKD and take place to hydrolysis and form the chance of glutinous form thing ketone, and then reduce the paper machine and lead to paper to act on one's own judgement the paper p
