Drying oven with double air channels for heat setting machine

The invention discloses a drying oven with double air channels for a heat setting machine. The drying oven comprises a heat-insulation oven body and two hot-air blowing devices. The hot-air blowing devices are positioned in the heat-insulation oven body, a heat-insulation door is arranged on the heat-insulation oven body, the hot-air blowing devices are connected with a flow guide plate, the flow guide plate is connected with air outlets of a fan, air inlets of the fan are sequentially connected with a natural gas heating system, and the two hot-air blowing devices are respectively positioned above and below needle plates. The drying oven has the advantages that the flow guide plate is arranged at the air outlets of the fan and is connected with the hot-air blowing devices, the double air channels can be formed by the two hot-air blowing devices, the two hot-air blowing devices are respectively positioned above and below the needle plates, accordingly, airflow can uniformly smoothly flow, resistance on the airflow can be reduced, and heat setting effects can be guaranteed; the drying oven is provided with the natural gas heating system and is high in heating-up speed, the heating-up preparation time of the drying oven can be shortened, the drying oven is low in pollution and easy to maintain, the energy utilization rate of the drying oven can be maximized, accordingly, production requirements can be met, the production cost can be greatly reduced, integral production procedures are environmental friendly, and energy can be saved in the integral production procedures.
