Description

[0003] For example, Chinese Patent No. CN118990678B discloses a cutting device and its cutting method suitable for various wind turbine blades. The cutting device drives the C-shaped frame to move through a multi-point support longitudinal movement component, the pre-cutting component cuts out a pre-cutting groove, and the rope cutting component performs segmented cutting along the pre-cutting groove.

A processing device for retired wind turbine blades includes a first roller conveyor 1, a cutting mechanism 3, a second roller conveyor 5, and a packing mechanism 7 installed on a base; it also includes a material distribution mechanism 4 and an end plate blanking mechanism 6; The first roller conveyor 1, the end pushing mechanism 2, the cutting mechanism 3, the material distribution mechanism 4, the second roller conveyor 5, the end plate blanking mechanism 6, and the packing mechanism 7 are distributed in sequence from right to left; the cutting mechanism 3 is used to cut the blade 8 into a front end 81, a rear end 82, and a web 83; As Figures 2-5 shown, the material distribution mechanism 4 includes a gantry mounting frame 41, a flipping support module 42, a guiding and limiting module 43, an end plate pulling module 44, and an end plate limiting module 45. Two groups of flipping support modules 42 for supporting the front end 81 and the rear end 82 are installed on the base, and a guiding and limiting module 43 is installed on the flipping support module 42; the gantry mounting frame 41 is fixedly installed on the base, and the end plate pulling module 44 and the end plate limiting module 45 are symmetrically installed on the gantry mounting frame 41; There are multiple second roller conveyors 5, and the rightmost second roller conveyor 5 is located below the two groups of flipping support modules 42, and the end plate blanking mechanism 6 is located outside the gantry mounting frame 41; three groups of packing mechanisms 7 for bundling the front end 81, the rear end 82 on the end plate blanking mechanism 6, and the web 83 on the second roller conveyor 5 are installed on the base.

[0024] In this embodiment, when the processing device for retired wind turbine blades works normally, the guiding and limiting module 43 is adjusted so that the guiding and limiting module 43 is located on the side of the web 83, and the web 83 is guided and limited through the guiding and limiting module 43, so that the front end 81, the rear end 82, and the web 83 move along the corresponding cutting positions; Position the larger end of the blade 8 on the left side, and convey the blade 8 from right to left through the first roller conveyor 1. Let the blade 8 move onto the flipping support module 42 after passing through the slitting mechanism 3. During this process, slit the blade 8 along both sides of the web 83 through the slitting mechanism 3; until the blade 8 moves a certain length; support the front end 81 and the rear end 82 through the flipping support module 42; then cut the front end 81, the rear end 82 and the web 83 from the main body part of the blade 8 along a direction perpendicular to the blade 8 through the slitting mechanism 3, so that the blade 8 is slit into three parts: the front end 81, the rear end 82 and the web 83; For the blade 8, the size of its main body part gradually becomes smaller from left to right, and the blade 8 is hollow inside.

Operate the flipping support module 42, and at the same time operate the end plate pulling module 44 to pull the front end 81 and the rear end 82 to move outward, so that the front end 81 and the rear end 82 fall onto the end plate discharging mechanisms 6 on both sides, and collect the front end 81 and the rear end 82 through the end plate discharging mechanisms 6; Repeat this operation until there are more webs 83 on the second roller conveyor 5 and stacked front ends 81 and rear ends 82 on the end plate discharging mechanisms 6. Convey the front ends 81 and the rear ends 82 to the packing mechanism 7 through the end plate discharging mechanisms 6, and convey the web 83 to the packing mechanism 7 through the second roller conveyor 5; bundle and pack the front ends 81, the rear ends 82 and the webs 83 respectively through the packing mechanism 7; When the blade 8 is cut to a small remaining part, the end pushing mechanism 2 pushes the blade 8, enabling the continuous cutting of the blade 8; Thus, the continuous cutting of the blade 8 is achieved. Through the cooperation of the flipping support module 42, the guiding and limiting module 43, the end plate pulling module 44, the end plate limiting module 45, the second roller conveyor 5, and the cutting mechanism 3, the blade 8 is cut into three parts: the front end 81, the rear end 82, and the web 83.

The limit adjustment cylinder 451 drives the connecting stop rod 453 to move downward through the parallel link 452, and blocks the outer sides of the front end 81 and the rear end 82 through the parallel link 452 and the connecting stop rod 453. The ball screw linear module 441 drives the moving mounting frame 442 to move horizontally. The moving mounting frame 442 drives the fixed cylinder 443, the moving plate 444, and the guide rod 445 to move horizontally, so that the staples 446 on the lower side of the moving plate 444 are aligned with the inner sides of the front end 81 and the rear end 82. The fixed cylinder 443 drives the moving plate 444 to move vertically under the limiting action of the guide rod 445, so that the staples 446 on the moving plate 444 are stapled on the front end 81 and the rear end 82. Then, the ball screw linear module 441 drives the moving mounting frame 442 to move outward, so as to drive the front end 81 and the rear end 82 to move outward through the fixed cylinder 443, the moving plate 444, and the staples 446, and make the front end 81 and the rear end 82 move onto the fixed roller conveyor 447. The limit adjustment motor 432 drives the rotating rod 433, the limit rod 435, and the connecting rod 436 to move, so that the connecting rod 436 moves away from the web 83, thereby causing the web 83 to fall onto the second roller conveyor 5. The first roller conveyor 1 continues to convey the blade 8 to the right, and the blade 8 is split into three parts: the front end 81, the rear end 82, and the web 83 by the fixed cutting knife 32. Insert the front end 81 and the rear end 82 on the right side into the front end 81 and the rear end 82 that have been slit on the left side respectively. The fixed cylinder 443 drives the moving plate 444 and the staples 446 to move vertically upward, so that the staples 446 are separated from the front end 81 and the rear end 82. The horizontal linear module 33 and the moving cutting knife 34 cut the front end 81, the rear end 82, and the web 83 on the right side from the main body part of the blade 8 again. Then, the inner front end 81 and rear end 82 can be continuously dragged outward through the ball screw linear module 441, the moving mounting frame 442, the fixed cylinder 443, the moving plate 444, and the staples 446, so as to realize inserting the front end 81 and the rear end 82 on the right side into the front end 81 and the rear end 82 on the left side. The web 83 continues to fall onto the second roller conveyor 5. The front end 81 and the rear end 82 after slitting can make full use of the stacking space when stacked. The limit adjustment cylinder 451 drives the parallel link 452 and the connecting lever 453 to move upward, so that the parallel link 452 and the connecting lever 453 no longer block the front end 81 and the rear end 82 from moving outward. The flipping cylinder 422 drives the rotating table 423 to flip outward. At the same time, the ball screw linear module 441 drives the moving mounting frame 442 and the fixed cylinder 443 to move outward. Thus, the front end 81 and the rear end 82 on the rotating table 423 are assisted to roll onto the fixed roller conveyor 447 through the moving plate 444 and the staples 446, and roll onto the material supporting roller 637 through the fixed roller conveyor 447. Then, the rear material supporting module 63 drives the threaded rod 633 to rotate through the transmission component two 632. The threaded rod 633 drives the moving column 635 and the material supporting frame 636 to move. The moving column 635 and the material supporting frame 636 move vertically under the limiting action of the guide rod 634, changing the overall length of the threaded rod 633 and the moving column 635. Thus, the front end 81 and the rear end 82 on the material supporting frame 636 and the material supporting roller 637 move downward, facilitating the subsequent stacking of the front end 81 and the rear end 82 on the upper side. Repeat this operation until there is a large stack of the web 83 on the second roller conveyor 5. The second roller conveyor 5 drives the web 83 to move leftward to the packing mechanism 7, and the packing mechanism 7 binds the web 83. After the material supporting roller 637 supporting the front end 81 and the rear end 82 moves downward to the lower side of the third roller conveyor 61, at this time, the third roller conveyor 61 supports the front end 81 and the rear end 82, and drives the front end 81 and the rear end 82 to move to the packing mechanism 7 through the third roller conveyor 61. The packing mechanism 7 binds the stacked front end 81 and rear end 82 respectively.

The rotation of the rotating rod 433 drives the limit rod 435 and the connecting rod 436 to move, thereby changing the position of the limit rod 435 so that the limit rod 435 aligns with both sides of the web 83, and the web 83 is limited and guided through the connecting lever 453. The larger end of the blade 8 is located on the left side. The blade 8 is conveyed from right to left through the first roller conveyor 1, and the blade 8 moves onto the rotating table 423 after passing through the fixed cutting knife 32. Step 2: The fixed cutting knife 32 cuts the blade 8 along both sides of the web 83; until the blade 8 moves a certain length; the front end 81 and the rear end 82 are supported by the rotating table 423; then the horizontal linear module 33 drives the movable cutting knife 34 to cut the front end 81, the rear end 82 and the web 83 from the main body part of the blade 8 along a direction perpendicular to the blade 8; thereby cutting the blade 8 into three parts: the front end 81, the rear end 82 and the web 83; the limit adjustment cylinder 451 drives the connecting stop bar 453 to move downward through the parallel link 452, and blocks the outer sides of the front end 81 and the rear end 82 through the parallel link 452 and the connecting stop bar 453; the ball screw linear module 441 drives the movable mounting frame 442 to move horizontally, and the movable mounting frame 442 drives the fixed cylinder 443, the movable plate 444 and the guide rod 445 to move horizontally, so that the staples 446 on the lower side of the movable plate 444 are aligned with the inner sides of the front end 81 and the rear end 82; the fixed cylinder 443 drives the movable plate 444 to move vertically under the limiting action of the guide rod 445, so that the staples 446 on the movable plate 444 are stapled on the front end 81 and the rear end 82, and then the ball screw linear module 441 drives the movable mounting frame 442 to move outward, thereby driving the front end 81 and the rear end 82 to move outward through the fixed cylinder 443, the movable plate 444 and the staples 446, so that the front end 81 and the rear end 82 move onto the fixed roller conveyor 447; the limit adjustment motor 432 drives the rotating rod 433, the limit rod 435 and the connecting rod 436 to move, so that the connecting rod 436 moves away from the web 83, thereby causing the web 83 to fall onto the second roller conveyor 5; Step 3: The first roller conveyor 1 continues to convey the blade 8 to the right, and cuts the blade 8 into three parts: the front end 81, the rear end 82 and the web 83 through the fixed cutting knife 32; inserts the front end 81 and the rear end 82 on the right side into the front end 81 and the rear end 82 that have been cut on the left side respectively; the fixed cylinder 443 drives the movable plate 444 and the staples 446 to move vertically upward, so that the staples 446 are separated from the front end 81 and the rear end 82; cuts the front end 81, the rear end 82 and the web 83 on the right side from the main body part of the blade 8 again through the horizontal linear module 33 and the movable cutting knife 34; then the inner front end 81 and rear end 82 can be continuously dragged outward through the ball screw linear module 441, the movable mounting frame 442, the fixed cylinder 443, the movable plate 444 and the staples 446; thereby realizing the insertion of the front end 81 and the rear end 82 on the right side into the front end 81 and the rear end 82 on the left side; the web 83 continues to fall onto the second roller conveyor 5; Step 4: The limit adjustment cylinder 451 drives the parallel link 452 and the connecting lever 453 to move upward, so that the parallel link 452 and the connecting lever 453 no longer block the outward movement of the front end 81 and the rear end 82. The flipping cylinder 422 drives the rotating table 423 to flip outward. At the same time, the ball screw linear module 441 drives the moving mounting bracket 442 and the fixed cylinder 443 to move outward. Thus, the front end 81 and the rear end 82 on the rotating table 423 are assisted to roll onto the fixed roller conveyor 447 through the moving plate 444 and the staples 446, and then roll onto the material supporting roller 637 through the fixed roller conveyor 447; then the rear material supporting module 63 drives the threaded rod 633 to rotate through the transmission component II 632. The threaded rod 633 drives the moving column 635 and the material supporting frame 636 to move. The moving column 635 and the material supporting frame 636 move vertically under the limiting action of the guide rod 634, changing the overall length of the threaded rod 633 and the moving column 635, thereby driving the front end 81 and the rear end 82 on the material supporting frame 636 and the material supporting roller 637 to move downward; Step 5: Repeat Steps 1 to 4 until there are more front ends 81 and rear ends 82 stacked on the web 83 of the second roller conveyor 5 and the end plate blanking mechanism 6. The front ends 81 and the rear ends 82 are conveyed to the packing mechanism 7 through the end plate blanking mechanism 6, and the web 83 is conveyed to the packing mechanism 7 through the second roller conveyor 5; the packing mechanism 7 bundles and packs the front ends 81, the rear ends 82 and the web 83 respectively.
