Multibarrel suitable for use on viscose filament yarn semi continuous centrifugal spinning machine and its supporting tray

The utility model discloses a multi-round barrel and a supporting plate of the multi-round barrel which can produce a plurality of spinning cakes in each position and each spindle of a viscose filament semi-continuing centrifugal spinning machine. The supporting plate is arranged on the bracket and a plurality of arrangement holes which correspond to the multi-round barrel are arranged on the supporting plate. A spindle of the multi-round barrel is on the supporting plate which corresponds to a plurality of centrifugal cylinders and an electric spindle. Besides, the multi-round barrel is once-formed and is shaped in a series of packaged barrels, and the bottom of the multi-round barrel where a plurality of drain holes are arranged is shaped in inclined surface. Because a triple-round barrel and a supporting plate of the triple-round barrel are arranged on the twisting surface of the semi-continuing centrifugal spinning machine, the utility model has the advantages that the device can strengthen the function of the triple-round barrel and the supporting plate of the triple-round barrel to proof water and corrosion and to exhaust gas. Thus, the span of the barrel and the supporting plate is prolonged and the repairing time and cost of the spinning machine is saved.
