If you want to cut different types, you need to manually replace the cutter head, which is time-consuming and labor-intensive. At the same time, the positions of the sealing rings cut by traditional cutting devices are neatly arranged, resulting in a low utilization rate of the rubber sheets. In order to solve the above problems, a rubber sheet cutting machine for the production of natural rubber sealing rings is provided.
