When extruder head works, pushing screw rod 30 rotates, and rotates against block 271 and generates centrifugal force, such spacing mandril 27
Rotation drive rod 31 is left in left end, and the mobile annulus 22 in such center moves right under the action of driving pressure spring 222, driving in this way
Under the action of dynamic connecting rod 23, the outside side of centre-drive plate 24 is mobile, and such lever unit 25 gradually becomes right low left high, this
Sample opening-closing plate 26, which moves inward, opens extrusion 200, and sizing material can be squeezed out from extrusion 200；
When extruder head stops working, pushing screw rod 30 is stopped rotating, and centrifugal force is lost against block 271, in reset tension spring
Under the action of 273, against mobile 22 return of annulus in 271 return of block driving center, eventually leads to lever unit 25 and gradually become the right side
High left low, opening-closing plate 26 is mobile outward to close extrusion 200.
The above content is only better embodiment of the invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
