The invention relates to a large-sized mineral wool machine, which is applicable to places with high consumption of mineral wools, rough sewing materials and poor work environments and comprises a main transmission and frame structure, a sewing operation surface, a pricking material transmission mechanism, a feeding adjusting component, a thread passing component, an eccentric wheel mechanism and an expansion material rolling mechanism. The sewing operation surface is provided with an operating plate and a moving connecting rod, the pricking material transmission mechanism is provided with a needle seat, the expansion material rolling mechanism is adjacent to the feeding adjusting component, the thread passing component is mounted at the rear end of the feeding adjusting component, the main transmission and frame structure is adjacent to the feeding adjusting component and is located on the other side, the eccentric wheel mechanism is mounted on one side of the main transmission and frame structure, the pricking material transmission mechanism is mounted below the main transmission and frame structure and is fixed on a frame, the sewing operation surface is mounted above the main transmission and frame mechanism, the needle seat of the pricking material transmission mechanism is located between the operating plate and the moving connecting rod, and a support of the sewing operation surface is mounted on the other side of the main transmission and frame structure. Various materials such as asbestos, rock wool, metal, plastics and the like can be used as sewing materials and sewing threads.
