In order to avoid the glue from entering the bearing 5, the problem of locking of the bearing 5 caused by glue leakage is solved from the root, the air outlet end is positioned above the bearing 5, and the purpose of avoiding the glue from flowing into the bearing 5 is achieved due to the blocking of the gas layer above the bearing 5.

Preferably, the gluing device further comprises a shaft sleeve 6, the shaft sleeve 6 is arranged in the shaft hole 26, and the gluing shaft 3 is rotatably arranged in the shaft sleeve 6 in a penetrating mode.

In order to further improve the uniformity of the gap distribution of the gas between the shaft sleeve 6 and the glue coating shaft 3, two or more shaft sleeve holes 62 can be uniformly distributed along the axial direction of the shaft sleeve 6.

As shown by the arrows in fig. 3, the gas flows out of the gas pipe connector 7, enters the vent hole 21, and then enters the gap between the shaft sleeve 6 and the support assembly 2 and the shaft sleeve hole 62 through the gas outlet end of the vent hole 21. The air flowing into the sleeve hole 62 is uniformly filled into the gap between the glue shaft 3 and the sleeve 6 along the annular air groove 31 of the glue shaft 3. After the gas enters each gap, the gas escapes upwards, and the glue in the glue melting box 1 cannot flow downwards from the gap, so that the problem of glue leakage of the gluing mechanism is solved.
