The fully automatic multi-layer composite mat production equipment for automotive interior trim produced by GWELl belongs to the technical field of composite mat production, and the composite mat production equipment includes a frame, a raw material feeding mechanism, a raw material tensioning mechanism, and a high-frequency fusing mechanism for fusing the composite mats sequentially set in the frame; the raw material feeding mechanism includes at least two discharge rollers, and the at least two discharge rollers are rotatably set in the frame; the raw material tensioning mechanism includes a tensioning component and at least two rollers, and at least one roller is set in the upper part of the frame and at least one roller is set in the lower part of the frame, and the upper part of the frame and the upper part of the frame and at least one roller are set in the lower part of the frame. The raw material tensioning mechanism includes at least two discharge rollers, at least two discharge rollers rotatably set in the frame; the raw material tensioning mechanism includes a tensioning component and at least two rollers both set in the frame, at least one roller is set in the upper part of the frame, at least one roller is set in the lower part of the frame, and the upper part of the frame and the lower part of the frame are spaced apart. The fully automatic multi-layer composite mat production equipment has a reasonable structure, which realises the automation of the whole process through the automatic feeding of raw materials, tensioning of raw materials by the tensioning mechanism, and finally cutting and compounding by the high frequency wave melting mechanism.
