Belt core formation device for conveying belts

The invention relates to production equipment of rubber conveying belts, in particular to a belt core formation device for the conveying belts. The belt core formation device comprises a coiled material uncoiling device, a padding cloth trimming device and a padding cloth coiling device, and further comprises an upper conveyer belt and a lower conveyer belt, wherein a cutting device I is arranged at the inlet position of the upper conveyer belt; a plurality of fitted pressure roller groups are arranged on the upper conveyer belt and before the cutting device I; height rack devices and a height adjusting rack device are arranged on the upper conveyer belt at intervals; a plurality of clamping roller groups are arranged at the tail end of the upper conveyer belt; a cutting device II is arranged between two of the clamping roller groups; a belt core coiling device and a padding cloth uncoiling device are arranged on the outer side at the tail end of the upper conveyer belt. Due to matched arrangement of the height rack devices and the height adjusting rack device, the belt core formation device has the advantages that production of relatively longer belt cores can be realized; no joints is formed in the production process.
