Environment-friendly food-grade synchronous belt

The utility model discloses an environment-friendly food-grade synchronous belt, and belongs to the field of transmission belt preparation. An environment-friendly food-grade synchronous belt comprises a belt body, a process rib groove located in one side of the belt body and a tensile layer, and the tensile layer extends in the length direction of the belt body, penetrates through the belt body and is exposed at the process rib groove. An adhesive layer and a PU filling layer are arranged in the process rib groove, the adhesive layer covers the tensile layer and the bottom wall and the side wall of the process rib groove, and the PU filling layer is attached to the adhesive layer. The environment-friendly food-grade synchronous belt has the beneficial effects that the environment-friendly food-grade synchronous belt is provided; a process rib groove is omitted, the PU filling layer and the belt body are formed in an extrusion mode, the connection strength is improved through the adhesive layer, and therefore
