And left end is articulated on the left side wall of driver slot 201；The middle part that center column spinner 31 is located at driver slot 201 is articulated with central gear
32；The central channel of annulus channel-shaped is formed on the inner sidewall of central gear 32；Central gear is formed on the side wall of central channel to support
Touch drive block 321；Center column spinner 31, which is located on the cylindrical surface of central channel, forms center rotation conflict drive block 311；Center
Rotation contradicts drive block 311 can contradict the conflict of drive block 321 with central gear；Several slide is formed on 201 side wall of driver slot
Guide rod 203；It is slided on sliding guide bar 203 and is provided with mobile guide block 22；The left end of sliding guide bar 203 is arranged with pressure spring
23；The left end of pressure spring 23 is fixed on the inner cylinder face of driver slot 201, right end is fixed on the left side of mobile guide block 22；
The lower end of mobile guide block 22 forms rack gear 221；Rack gear 221 can be engaged with central gear 32；Guide rod 41 is resisted against movement
On the end face of guide pad 22 and as the movement of mobile guide block 22 can be slided along guide groove 202；Guide groove 202 is by arc
Guide groove and a pair of radial linear guide groove composition that arc guide groove both ends are set；A pair of radial linear guide groove it
Between angle of the angle between extrusion 200 half and direction be arranged inwardly；A pair of radial linear guide groove
By the Pivot axle of center column spinner 31；The Pivot axle of arc guide groove and the Pivot axle of center column spinner 31
Collinearly；Radius of the direction of sliding guide bar 203 perpendicular to the Pivot axle for crossing arcuate guide groove center and arc guide groove
The rectilinear direction at place.
As shown in Figure 1 and Figure 2, mobile guide block 22 is the rectangle that upper end is shaped to isosceles trapezoid；Rack gear 221 is molded over shifting
On the lower end surface of action-oriented block 22；The upper surface of mobile guide block 22 forms the limiting slot 220 of semicolumn channel-shaped；Guide rod 41
It is resisted against the upper end of mobile guide block 22.
As shown in Figure 1, Figure 2, Figure 4 shows, the anti-reverse guide groove of the radial direction of rectangle is formed on the left side of anti-inverse ring 40
401；Guide rod 41, which slides, to be arranged in anti-reverse guide groove 401；Anti-reverse pressure spring 42 is provided in anti-reverse guide groove 401；Anti-reverse pressure spring
42 outboard end is fixed on the lateral wall of anti-reverse guide groove 401, inner end is fixed on guide rod 41.

Left end form the left wide right narrow frustum of a cone；Adjust the circular cone of the inside side walls of extrusion cavities 400 and the left end of pushing screw rod 30
Table top is on same circular conical surface；The right side diameter of the frustum of a cone of the left end of pushing screw rod 30 is identical as the diameter of pushing screw rod 30
And the Pivot axle of the two is conllinear.
The working principle of lever driving anti-reversing clutch:
When extruder head works, pushing screw rod 30 rotates counterclockwise, is rotated by center and contradicts drive block 311, central gear
Contradict drive block 321 drive central gear 32 counterclockwise rotate, central gear 32 by rack gear 221 drive mobile guide block 22 to
It moves left, guide rod 41 is under the collective effect of mobile guide block 22 and anti-reverse pressure spring 42, and guide rod 41 is from the right side of guide groove 202
The bottom of the linear guide groove of side reaches the bottom of the linear guide groove in the left side of guide groove 202, adjusts extrusion cavities 400 and squeezes out
Mouth 200 is aligned, and sizing material can be extruded；The central gear 32 that mobile guide block 22 is rotated counterclockwise always later is compressed on most
Left end, i.e. guide rod 41 are in the bottom of the linear guide groove in the left side of guide groove 202, adjust extrusion cavities 400 always with extrusion
Mouth 200 is aligned；
After extruder head stops working, pushing screw rod 30 rotates clockwise certain angle, and such center rotation contradicts drive block
311 contradict drive block 321 far from central gear, and such central gear 32 is in free rotation state, then mobile guide block 22
It moves right under the action of pressure spring 23, guide rod 41 is under the collective effect of mobile guide block 22 and anti-reverse pressure spring 42；Guiding
Bar 41 reaches the bottom of the linear guide groove on the right side of guide groove 202 from the bottom of the linear guide groove in the left side of guide groove 202,
I.e. anti-inverse ring 40 rotates clockwise move angle, adjusts extrusion cavities 400 at this time and is staggered with extrusion 200, and sizing material cannot be extruded,
The sizing material of left end can not countercurrently return to the right end of barrel 10.
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
