Manufacturing method of flexible conveying belt

The invention relates to the technical field of rubber conveying belts, in particular to a manufacturing method of a flexible conveying belt. The manufacturing method comprises the following specificsteps of obtaining a rubber material through plastifying and mixing so as to prepare a base belt, arranging a canvas core inside the base belt, and performing cold pressing molding; carrying out batching of a triangular area rubber material; obtaining the triangular area rubber material through plastifying and mixing; carrying out split vulcanization, firstly pressing the base belt and then vulcanizing; then grinding in a range of 15 cm wide on the two sides of the base belt, and performing one-time vulcanization after butting the base belt and the triangular area rubber material; and completing the manufacturing of the flexible conveying belt. According to the manufacturing method of the flexible conveying belt, through reasonable procedures and the design of the formula, the modulus of the triangular area rubber
