A butterfly spring is installed under the carriage to ensure stable clamping of materials of different thicknesses. S7: The discharge port is composed of two rows of rollers and a top-opening cylinder. The servo drives the discharge port to be opened, and the lower feeding mechanism feeds the material in, then clamps it, and the servo motor drives it out; S8: Enter the indexing feeding unit, which has a rotating shaft and a driving servo motor at the rear and a servo diversion module at the front, which can circulate and feed 10 channels; S9: Entering into 10 flow channel pressing groups, there is a pressing mechanism and a lower driving roller group every 500 mm, which can ensure the delivery of materials longer than 500 mm, and there is a step-down speed reduction between the driving roller groups; S10: There are 10 photoelectric sensors at the rear of the pressing group corresponding to 10 flow channels, which check whether there is material in the flow channels and provide signals to the servo diversion module; S11: Materials in various flow channels converge in the confluence group; S12: The left and right pressing rollers squeeze the material and send it out to the molding equipment; S13: The feeding processes of the left and right feeding mechanisms are consistent and will not be repeated.
