The left end of the first blanking chute plate 8 is fixedly connected with the top of the right side wall of the second support plate 714.
[0026] A rotating handle is fixedly connected to the outer wall of the leftmost straightening wheel 412 of the first straightening mechanism 2.
[0027] According to the pipe diameter of the corrugated pipe, rotate the first bolts 46 of the three straightening mechanisms (the first straightening mechanism 2, the second straightening mechanism 3, and the third straightening mechanism 4). Since the first bolts 46 are threadedly connected with the first fixed nuts 45, the first bolts 46 can drive the springs 48 to move up and down, adjust the force exerted by the springs 48 on the first sliders 43, so as to adapt to corrugated pipes of different pipe diameters, avoid the corrugated pipes being extruded and deformed due to excessive force, and at the same time avoid the straightening wheels 412 being unable to straighten the corrugated pipes due to too small force.
[0028] The corrugated pipe enters the device from the leftmost first straightening mechanism 2. At first, use the rotating handle to rotate the straightening wheel 412 until the corrugated pipe is sent to the top of the feeding wheel 59. The first motor 510 drives the feeding wheel 59 to rotate, and conveys the corrugated pipe to the right through friction.
[0029] When the corrugated pipe passes through the first straightening mechanism 2, the second straightening mechanism 3 and the third straightening mechanism 4, due to the staggered distribution of the straightening wheels 412 and the elastic action of the springs 48, the corrugated pipe is gradually straightened to a flat state;
[0030] When the corrugated pipe passes through the straightening mechanism and is conveyed to the position of the cutting mechanism 7 along the guide groove plate 10, the corrugated pipe falls into the fixing groove 717 of the fixed seat 713 and the movable seat 716. Since the fixing groove 717 is V-shaped, the corrugated pipe can be stably placed;
[0031] The second motor 77 starts, driving the worm 78 to rotate. The worm 78 drives the worm wheel 711 to rotate, thereby driving the support shaft 710 and the cutting wheel 712 to rotate. At the same time, the hydraulic cylinder 75 works, pushing the connecting plate 76 and the transmission box 73 to move up and down along the guide rail 72, driving the cutting wheel 712 to cut the corrugated pipe;
[0032] The cut corrugated pipe segments fall into the second blanking groove plate 718 and slide into the first blanking groove plate 8, and finally fall into the receiving box 9. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
