Production method of felt surface conveying belt

The invention discloses a production method of a felt surface conveying belt. The production method comprises the following steps that steel wires being 0.8-1 mm in diameter are uniformly distributedthrough a wire distribution and arrangement system and are arrayed into uniformly-spaced steel wire rows with the spacing being 0.5-0.6 mm; the steel wire rows are subjected to prestretching shaping through a steel wire stretching device and are arrayed tidily; the steel wire rows are guided into an extrusion injection molding machine, TPU plastic particles are added to the extrusion injection molding machine, and high-power extrusion is carried out, so that a preliminary strip billet is obtained; a felt output device is arranged at an extrusion port of the extrusion injection molding machine,felt is output by the felt output device and is bonded with one side of the preliminary strip billet, the strip billet bonded with the felt is pressed, and thus a complete felt surface conveying beltis obtained; and the felt
