Technical Field

[0001] The invention relates to the field of rubber processing, and in particular to processing equipment for ethylene propylene diene monomer halogen-free elastic rubber material. Background Art

[0002] With the development of industrial technology, modern rubber processing technology has become more and more perfect. EPDM rubber materials have better heat resistance and low temperature gentleness. Waste EPDM rubber materials can be recycled and reused, but the shapes and sizes of waste EPDM rubber materials are different. These waste EPDM rubber materials are easy to get stuck in the crushing device during the crushing process.

[0003] Secondly, during the heating and remaking process of the EPDM rubber material, there is still a lot of moisture in the EPDM rubber material. These moisture will form small bubbles inside the rubber material when heated. If these small bubbles are not removed, the quality of the rubber material will be affected. Summary of the invention

[0004] The object of the present invention is to provide a processing device for halogen-free elastic rubber material of EPDM. When the device is in use, chopped rubber material enters into an extrusion box through a blanking channel and is heated and softened. A hydraulic press applies pressure to the rubber material and pushes it out of the extrusion box and into sheets. The sheet-like rubber material is cut into four strips by a slitting blade inside the slitting box. The four material strips are twisted ninety degrees in a turning channel and merged together again to be squeezed in the middle of a pressure roller. The bubbles inside the rubber material will be squeezed out. The extruded rubber material can be sent back to the extrusion box from a charging port for a second cycle of processing to solve the problems raised in the above-mentioned background technology.
