[0009] Preferably, the temperature of the glue in the front glue spraying tube and the back glue spraying tube is between 80-130°C.

[0010] The technical effect of the utility model is mainly reflected in that glue is directly sprayed onto the angle area between the paper and the front surface glue roller and the back surface glue roller through the front glue spray hose and the back surface glue spray hose, so that the paper can be completely immersed in the glue, and the heat consumption of the glue is less, avoiding premature cooling, so that the glue is convenient to penetrate into the inside of the paper under the squeezing of the front surface glue roller and the back surface glue roller, so that the produced paper is more fold-resistant.
