Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, with
Lower embodiment combination attached drawing is specifically addressed the interchangeable screw rod in the utility model.
Interchangeable screw rod in the present embodiment is arranged in plastic extruder, for the extrusion of plastics, including screw body
10 and discharging bar unit.The bar unit that discharges includes virgin material discharging rod 11, additive color discharging rod 12 and feed back discharging rod 13.
Fig. 1 is the axial view of screw body in the embodiments of the present invention.
As shown in Figure 1, the outer surface of screw body 10 is provided with the external screw thread 14 for being threadedly coupled with discharging bar unit.
Discharging bar unit is threadedly coupled with screw body 10, including virgin material discharging rod 11, additive color discharging rod 12 and feed back
Discharging rod 13.Wherein, virgin material discharging rod 11 is for processing completely new vinyon；Additive color discharging rod 12 is added with for processing
