The invention provides a self-heating cotton collection apparatus, comprising a cotton guiding chamber, a stainless steel mesh belt, a cotton collecting box, a negative pressure blower fan, an adhesive spraying pipe and an infrared radiation hot plate. The infrared radiation hot plate is installed in the cotton collection apparatus and comprises a thermal-isolation heat-preserving layer, a heatproof heat-preserving heating layer and a heat-conducting radiation layer, wherein the heating layer is a heating diode, and an infrared radiation paint is adhered on the heat-conducting radiation layer. The self-heating cotton collection apparatus employs infrared radiation heat transfer and utilizes the characteristics of strong penetrating force, high heating efficiency and the like of infrared rays to realize long-distance heat-curing of cotton silk; i.e., curing of the cotton silk is started before falling of the cotton silk on a stainless steel mesh, and the cotton silk and the stainless steel mesh contact in a solid phase manner after the cotton silk falls on the stainless steel mesh, thereby producing a good abhesion effect. Through curing of cotton felt in advance, the temperature of a curing furnace can be properly reduced, and time spent in a curing furnace can be effectively decreased.
