[0021] The stirring and mixing device for the PVC cable particle raw material disclosed by the utility model has the following steps when in use:

[0022] The initial step is that an operator sets the bagging weight value by increasing and decreasing the keys, and the display screen 320 displays the set bagging weight value; then the main controller controls the sealing motor 314 to drive the rectangular sealing plate 311 to seal, so as to prevent the un-stirred material from entering the longitudinal conveying auger 308; the operator conveys the material to be stirred into the horizontal cylinder 301 through the inclined feeding channel 306; then the operator clamps the upper opening of the transfer bag between the upper side of the bag opening supporting ring 331 and the L-shaped clamping rod 327;
