Description

Technical Field

[0001] The utility model relates to the technical field of rubber vulcanization, in particular to a novel continuous vulcanization device with high efficiency and energy saving. Background Art

[0002] The production of rubber strips is to extrude the mixed rubber through a die through an extruder, first heat and vulcanize it in a microwave vulcanization box, then heat and mature it in multiple hot air vulcanization boxes, and finally cool and pull it to obtain the rubber strip product. A transition device needs to be set between the microwave vulcanization box and the hot air vulcanization box, and between adjacent hot air vulcanization boxes. Each vulcanization box is equipped with a conveyor belt. The transition device connects the outlet of the previous conveyor belt and the inlet of the next conveyor belt at intervals to ensure the transportation of the rubber strip.

[0003] The transition devices currently on the market have the following defects:

[0004] 1. The distance between the inlet and outlet of two adjacent conveyor belts is 8-10cm. The distance is long, and manual labor is required to stand in front of the transition device to hand over the products between the two conveyor belts, which undoubtedly increases the labor cost;
