When the screw 13 pushes the glue solution to move in the sol cavity 12, the glue solution also moves downwards along the sol cavity 12 under the action of gravity, so that the screw 13 can push the glue solution to move in the sol cavity 12 conveniently.
The communicating cavity 31 and the first driving device 14 are arranged at two ends of the sol cavity 12, the sol container 11 is arranged at one end of the sol cavity 12 close to the first driving device 14, the sol liquid flows to the other end through one end of the sol cavity 12, the contact time of the sol liquid and the screw 13 is increased, and the screw 13 can conveniently perform sol operation.
