Specific embodiment
As shown in Figure 1 and Figure 2, a kind of injection molding extruder head sizing material anti-reversing clutch, including barrel 10, guide part 20, sizing material are anti-reverse
Device 30 and pushing screw rod 40；Guide part 20 is made of the guiding main part 22 of left part and the columned support portion 21 of right part；It leads
The left side of the inside of barrel 10 is fixed on by support portion 21 to part 20；The anti-of cylindrical shape is formed on the left side of support portion 21
Inverse slot 200；The telescopic chute 202 for having screw thread poroid on the left side wall of anti-reverse slot 200；Be oriented to main part 22 right end cylindrical surface at
Type has several extrusions 201；Extrusion 201 is connected to anti-reverse slot 200；The right part inside barrel 10 is arranged in pushing screw rod 40；
Rectangular escape groove 400 is formed on the left side of pushing screw rod 40；Anti- reverse driven spiral shell is fixed on the right side wall of escape groove 400
Rasp bar 34；The left end of anti-reverse driven threaded rod 34 is articulated on the left side wall of telescopic chute 202；Sizing material anti-reversing clutch 30 includes anti-reverse
Ring 31；The anti-rotation of inverse ring 31 moves horizontally on anti-reverse driven threaded rod 34；Connection circle is articulated on the right side of anti-inverse ring 31
Ring 322；It connects uniform vertical on the right side of annulus 322 and is fixed with several connecting rods 321；The right end of connecting rod 321 is fixed on
On the rectangular torsional-spring supported plate 32 cooperated with escape groove 400；Torsional-spring supported plate 32 is set on anti-reverse driven threaded rod 34 simultaneously
And it is plugged in escape groove 400；Reduction torsion spring 33 is fixed on the left side of torsional-spring supported plate 32；Reduction torsion spring 33 is set in anti-
On reverse driven threaded rod 34 and left end is fixed on the right side of anti-inverse ring 31.
As shown in Figure 1 and Figure 2, the sideline of the right end outlet of anti-reverse slot 200 forms chamfering；The left side side of anti-inverse ring 31
Line forms chamfering；The fillet surface of the right end outlet of anti-reverse slot 200 is parallel with the fillet surface of anti-31 left side of inverse ring.
As shown in Figure 1 and Figure 2, cricoid isolation ring 312 is formed on the right end of anti-inverse ring 31；The outside cylinder of isolation ring 312
Face is shaped to the circular conical surface that diameter to from left to right becomes smaller；The diameter phase of the inner cylinder face diameter of isolation ring 312 and pushing screw rod 40
Same and the two Pivot axle is conllinear；The length of the left and right directions of isolation ring 312 is greater than the row of anti-31 left and right directions of inverse ring
Journey.
As shown in Figure 1 and Figure 2, the left side of anti-inverse ring 31 forms columned connecting column 311；The outer circle of connecting column 311
Cylinder forms screw thread；Connecting column 311 can be screwed onto telescopic chute 202；When anti-inverse ring 31 is in right end, connecting column 311
Left side with guiding the right side of main part 22 it is concordant.
As shown in Figure 1 and Figure 2, the bore dia that torsional-spring supported plate 32 is used to be set in anti-reverse driven threaded rod 34 is greater than anti-reverse
Drive the diameter of threaded rod 34.
The working principle of extruder head sizing material anti-reversing clutch:
When extruder head does not work, pushing screw rod 40 does not rotate, and anti-inverse ring 31 is resisted against in support portion 21 at this time, and sizing material can not
It squeezes out；
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 under the action of, promote the rotation of anti-inverse ring 31 to move right, at this moment reduction torsion spring 33 is gathered strength, when anti-reverse
Ring 31 is moved to right end, and connecting column 311 is detached from telescopic chute 202；At this time anti-inverse ring 31 with anti-reverse driven threaded rod 34 together
Rotation, such sizing material can squeeze out, as shown in Figure 1；When pushing screw rod 40 is stopped rotating, reduction torsion spring 33 is had an effect, and drives anti-
31 counter-rotating of inverse ring, so anti-inverse ring 31 rotation are moved to the left, until anti-inverse ring 31 is resisted against in support portion 21, such sizing material
It can not squeeze out.
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.
