The invention relates to a conveyor belt production line and process. The conveyor belt production line comprises a single-layer production line used for producing a single-layer conveyor belt, and amulti-layer production line used for producing a multi-layer conveyor belt; the multi-layer production line comprises a winding machine I, a winding tractor I, an unwinding machine I, a cloth drying oven, an unwinding tractor I, a coating machine I, ovens I, a laminating heater I, a laminating machine, a laminating heater II, ovens II, a coating machine II, an unwinding tractor II and an unwindingmachine II which are arranged in sequence adjacently; and the single-layer production line comprises the unwinding machine I, the cloth drying oven, the unwinding tractor I, the coating machine I, the ovens I, the winding tractor I and the winding machine I in the machining flow direction in sequence. According to the conveyor belt production line and process provided by the invention, through adding to the cloth drying oven equipment before the coating procedure, cloth is subjected to pre-baking treatment firstly, and then conveyed into the coating machine and the oven for coating and bakingtreatment.
