Hot Air Discharger with Double Helix Pipe Structure for Edge Bender

Hot air discharge device 200 of the spiral tube structure for the edge bander of the present invention is applied to the hot-melt adhesive to the unfinished edge surface 11 of the plate-shaped board 10 and the edge for attaching the finishing material 30 to it In a bender device， as a hot air discharge device for an edge bender for enhancing adhesion by discharging hot air toward the adhesive surface of the edge surface 11 and the finishing material 30 of the board 10， the heater rod 210 heated to a constant temperature )， A spiral heating tube 220 that winds the outer circumferential surface of the heater rod 210 in a spiral form and heats the air flowing through the air path by the heat of the heater rod 210 and forming an air path along the inside. ， The heat preservation member 230 is formed to be wrapped to surround the spiral heating tube 220， the heat shield case 240 wrapped so that the heat preservation member 230 is not exposed to the outside， the outlet of the spiral heating tube 220 Sat for discharging hot air Outgoing nozzle 250， Air compressor 270 to supply compressed air to the inlet of the spiral heating tube 220 so that hot air is discharged at a specific pressure from the outlet of the spiral heating tube 220， and the spiral heating tube 220 and the air It is installed between the compressor 270 and includes an on-off valve 280 that opens and closes the air flow path of the spiral heating tube 220 according to an electrical signal.
