The tail consists of a tailstock and a tail shaft. The tailstock has a total length of 1400mm and a height of 346mm . The upper end of the connection between the tailstock and the middle groove is welded with a wear-resistant alloy block on the upper edge of the steel, thereby improving the service life of the tailstock. The column feet on both sides of the tailstock are used to support and fix the tail blades. The tail shaft is installed on the tail frame, and is composed of a guide sprocket, sleeve shaft, positioning sleeve, bearing seat, cushion seal and two sets of 3613 bearings. The guide wheel of the tail shaft of the machine adopts a sprocket or drum structure, both of which can ensure the gong ring is properly meshed on it, reducing operating accidents.
