The operation principle of extruder head sizing material anti-reversing clutch：
When extruder head does not work, pushing screw rod 40 is not rotated, and now anti-inverse ring 31 is resisted against in supporting part 21, and sizing material can not
Extrusion；
When extruder head works, pushing screw rod 40 rotates, and drives anti-reverse driven threaded rod 34 to rotate, in anti-reverse driven threaded rod
34 and telescopic chute 202 in the presence of, promote the rotation of anti-inverse ring 31 to move right, at this moment position torsion spring 33 is gathered strength, when anti-inverse ring
31 are moved to low order end, and connecting pole 311 departs from telescopic chute 202；Now anti-inverse ring 31 is revolved with anti-reverse driven threaded rod 34 together
Turn, such sizing material can be extruded, as shown in Figure 1；When pushing screw rod 40 is stopped the rotation, reduction torsion spring 33 is had an effect, and drives anti-reverse
The counter-rotating of ring 31, so anti-inverse ring 31 rotation are moved to the left, until anti-inverse ring 31 is resisted against in supporting part 21, such sizing material without
Method is extruded.
