The one end of part away from the second pipe fitting enters, and enters the second pipe fitting along the first pipe fitting, then leads to extrusion along the second pipe fitting.
The first pipe fitting is vertically arranged with the second pipe fitting in the present embodiment, is easy to control compressed gas to be entered by the first pipe fitting
Throughput and speed during the second pipe fitting, to avoid because throughput is not enough or air velocity is too small causing that swelling heat can not be reached
Fusibleness plastic cement, can also avoid causing hot melt plastic cement expansion effect poor because throughput is excessive or air velocity is excessive.
In order that the hot melt plastic cement being distributed in extrusion blow pipe can preferably expand, in extrusion blow pipe in the present embodiment
Hot melt plastic cement is heated.Heating can be realized through in the following manner：Heating member, example are set towards the surface of extrusion blow pipe in breather pipe
Hot melt plastic cement as heating member can be pointed to around heating member by electrically heated mode is heated.
Hold, the hot melt plastic cement of the one end for the remote extrusion being distributed in extrusion blow pipe in the case where squeezing the promotion of push piece, by
Moved to extrusion one end away from extrusion；In moving process, hot melt plastic cement is again by the heating member of ventilation tube outer surface
Heat effect heated, the hot melt plastic cement at extrusion is expanded by compressed gas.
