Glue solution smearing structure

The glue solution smearing structure comprises a glue solution cylinder and a gas cylinder, a liquid outlet pipe is arranged at the upper end of the glue solution cylinder, and a discharging head is detachably connected to the liquid outlet pipe; the gas cylinder is connected to the bottom end of the glue solution cylinder, an exhaust valve is arranged at the gas outlet end of the gas cylinder, and the gas outlet end of the exhaust valve is communicated with the glue solution cylinder. The automatic gluing device has the beneficial effects that automatic extrusion of a glue solution is achieved through air pressure, automatic gluing is adopted, the gluing efficiency is high, the glue solution extrusion amount is constant, and the gluing quality is high; the discharging head can be detached and washed, the discharging head is prevented from being blocked, the discharging pipe is sealed through the sealing cover, the discharging pipe is prevented from being blocked, and waste of glue liquid which is not complet
