step 5: outward release: after the rotary cutting component 3 rotates 180 degrees anticlockwise, the lower telescopic cylinder II 412 is used for enabling the end face gear II 410 which is originally arranged in front but is arranged behind to be meshed with the lower end face gear I408, the lower gear II 407 and the rack II 403 are meshed to enable the gear II 407 to rotate anticlockwise, the lower end face gear I408 and the lower end face gear II 410 are meshed to enable the threaded rod 311 which is turned 180 degrees to rotate anticlockwise, the threaded rod rotates and drives the moving block 312 to move forwards, the moving block 312 moves forwards and drives the linkage ring 308 to rotate clockwise, the cutting mechanism is dispersed outwards, and a worker immediately takes the cut corrugated pipe 6 away from the left side of the rotary cutting component 3;

step 6: returning to a preset state: the piston rod of the first telescopic cylinder 207 extends rapidly, the lower meshing plate 210 is meshed with the lower portion of the synchronous belt 214, the cutting-off cutter 305f moves to the initial position towards the right synchronously, the first telescopic cylinder 207 is used for enabling the lifting plate 208 to be located at the middle position of the synchronous belt 214, the rotating motor 315 works and drives the first gear 316 to rotate anticlockwise, the rotary cutting assembly 3 rotates 180 degrees clockwise, the upper first face gear 406 is meshed with the lower second face gear 408 through the upper second telescopic cylinder 412, and the next cutting face is waited to appear.

In summary, the cutting device for corrugated pipes in the present invention is, in practical use: the linear speed of the synchronous belt 214 is kept consistent with the forming and demoulding speed of the corrugated pipe 6 through the work of the displacement motor 211, when the cutting edge of the cutting knife 305f is coplanar with the cutting surface of the corrugated pipe 6, the piston rod of the telescopic cylinder 207 is rapidly contracted, the upper meshing plate 209 is meshed with the upper edge part of the synchronous belt 214, the cutting knife 305f is synchronously moved, in the moving process, the threaded rod 311 obtains power through a corresponding gear transmission structure, the cutting mechanism is inwards folded, when the clamping wheel 305c is in contact with the threaded pipe 6, the folding is continued until the cutting knife 305f penetrates into the interior of the corrugated pipe 6 and stops folding, then the rotary motor 315 works and drives the cutting mechanism to rotate 180 degrees anticlockwise, and the annular cutting of the corrugated pipe 6 is completed. Therefore, the cutting device for the corrugated pipe has the characteristics of reasonable structure, convenience in use, high automation degree, good linkage of components and smooth and flat cut surface, and effectively avoids the defects and drawbacks caused by manual operation.

The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
