Description

Technical Field

[0002] After being retired, wind turbine blades are usually recycled by physically adding glass fiber to building materials, or by pyrolysis to recycle the raw materials. However, wind turbine blades are large in size and need to be cut using slitting equipment before any recycling can be carried out.

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The "left", "right", "front", "rear", "upper" and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0043] Embodiment 1: In some embodiments, please refer to the Figures 1 - 5 drawings in the specification, a processing device for retired wind turbine blades includes a first roller conveyor 1, a slitting 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;

[0044] The first roller conveyor 1, the end pusher mechanism 2, the cutting mechanism 3, the material distributing 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 for cutting the blade 8 into a front end 81, a rear end 82 and a web 83;

[0045] As Figures 2 - 5 shown, the material distributing 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 sets of flipping support modules 42 respectively used 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;

[0046] A plurality of second roller conveyors 5 are provided, and the rightmost second roller conveyor 5 is located below the two sets of flipping support modules 42, and the end plate blanking mechanism 6 is located outside the gantry mounting frame 41; three sets of packing mechanisms 7 respectively used for bundling the front end 81 on the end plate blanking mechanism 6, the rear end 82 and the web 83 on the second roller conveyor 5 are installed on the base.

[0047] In this embodiment, when the processing device for the retired wind turbine blade works normally, the guiding and limiting module 43 is adjusted to make the guiding and limiting module 43 located at 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;

[0048] Make the end with the larger size of the blade 8 located on the left side, and the blade 8 is conveyed from right to left through the first roller conveyor 1, so that the blade 8 moves onto the flipping support module 42 after passing through the cutting mechanism 3. During this process, the blade 8 is cut along both sides of the web 83 through the cutting mechanism 3; until the blade 8 moves a certain length; the front end 81 and the rear end 82 are supported by the flipping support module 42; then the front end 81, the rear end 82 and the web 83 are cut off from the main body part of the blade 8 along the direction perpendicular to the blade 8 through the cutting mechanism 3, so that the blade 8 is cut into three parts: the front end 81, the rear end 82 and the web 83;

[0049] 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. After the blade 8 is cut into the front end 81, the rear end 82 and the web 83, the right front end 81 can be inserted into the left front end 81, and the right rear end 82 can be inserted into the left rear end 82;

[0050] The outer sides of the front end 81 and the rear end 82 are blocked by the end plate limiting module 45, and the cut-off front end 81 and rear end 82 are pulled by the end plate pulling module 44 to move outward; then the operation guiding and limiting module 43 gives way to the web 83, so that the web 83 falls from between the two flipping and supporting modules 42 onto the second roller conveyor 5;

[0051] Then the first roller conveyor 1 continues to convey the blade 8 to the right, and the blade 8 is cut into three parts: the front end 81, the rear end 82, and the web 83 by the cutting mechanism 3; the front end 81 and the rear end 82 on the right are respectively inserted into the front end 81 and the rear end 82 that have been cut on the left, and then the front end 81, the rear end 82, and the web 83 on the right are cut off from the main body part of the blade 8 again by the cutting mechanism 3; thus, the front end 81 and the rear end 82 on the right are inserted into the front end 81 and the rear end 82 on the left; the web 83 continues to fall onto the second roller conveyor 5; the cut-off front end 81 and rear end 82 can make full use of the stacking space when stacked;

[0052] The end plate limiting module 45 is retracted so that the end plate limiting module 45 no longer blocks the outward movement of the front end 81 and the rear end 82. The flipping and supporting module 42 is operated, and at the same time, the end plate pulling module 44 is operated 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 blanking mechanisms 6 on both sides, and the front end 81 and the rear end 82 are collected by the end plate blanking mechanisms 6;

[0053] This operation is repeated 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 blanking mechanisms 6. The front ends 81 and the rear ends 82 are conveyed to the packing mechanism 7 by the end plate blanking mechanisms 6, and the webs 83 are conveyed to the packing mechanism 7 by the second roller conveyor 5; the front ends 81, the rear ends 82, and the webs 83 are respectively bundled and packed by the packing mechanism 7;

[0054] When the remaining part of the blade 8 is less during cutting, the blade 8 is pushed by the end push mechanism 2 to enable continuous cutting of the blade 8;

[0055] Thus, continuous cutting of the blade 8 is achieved, and through the cooperation of the flipping and supporting 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, and adjacent front ends 81 are stacked together, and adjacent rear ends 82 are stacked together, realizing full utilization of space; there is supporting material such as balsa wood in the web 83 part, and the front end 81 and the rear end 82 are mainly made of materials such as fiberglass; the material compositions of the web 83, the front end 81, and the rear end 82 are different. Packing the front end 81, the rear end 82, and the web 83 separately is convenient for subsequent separate processing of the front end 81, the rear end 82, and the web 83.

[0071] In this embodiment, the limit adjusting motor 432 drives the rotating rod 433 to rotate. 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 is aligned with both sides of the web 83, and the web 83 is limited and guided through the connecting stop rod 453;

[0072] 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 turntable 423 after passing through the fixed cutting knife 32. During this process, the blade 8 is slit along both sides of the web 83 by the fixed cutting knife 32; until the blade 8 moves a certain length; support the front end 81 and the rear end 82 by the turntable 423; then the horizontal linear module 33 drives the moving 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; thus 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;

[0073] The ball screw linear module 441 drives the moving mounting bracket 442 to move horizontally. The moving mounting bracket 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, and then the ball screw linear module 441 drives the moving mounting bracket 442 to move outward, thus driving 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, so that the front end 81 and the rear end 82 move onto the fixed roller conveyor 447;

[0074] 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, and thus the web 83 falls onto the second roller conveyor 5;

[0075] 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; 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; 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 through the horizontal linear module 33 and the moving 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 moving mounting bracket 442, the fixed cylinder 443, the moving plate 444 and the staples 446; thus 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; the slit front end 81 and rear end 82 can make full use of the stacking space when stacking;

[0076] The limit adjustment cylinder 451 drives the parallel connecting rod 452 and the connecting stop lever 453 to move upward, so that the parallel connecting rod 452 and the connecting stop 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 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 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, so as to drive the front end 81 and the rear end 82 on the material supporting frame 636 and the material supporting roller 637 to move downward, facilitating the subsequent stacking of the front end 81 and the rear end 82 on the upper side; repeat this operation until the webs 83 on the second roller conveyor 5 are stacked more. The second roller conveyor 5 drives the webs 83 to move leftward to the packing mechanism 7, and the packing mechanism 7 binds the webs 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, and the packing mechanism 7 binds the stacked front end 81 and rear end 82 respectively.

[0078] Step 1: The limit adjustment motor 432 drives the rotating rod 433 to rotate.

[0079] 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 the direction perpendicular to the blade 8; thus, 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 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, so as to drive 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, so that the web 83 falls onto the second roller conveyor 5;

[0080] Step 3: The first roller conveyor 1 continues to convey the blade 8 to the right, and the blade 8 is cut into three parts: the front end 81, the rear end 82 and the web 83 by the fixed cutting knife 32; the front end 81 and the rear end 82 on the right side are respectively inserted into the front end 81 and the rear end 82 that have been cut on the left side; 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; the horizontal linear module 33 and the movable 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 movable mounting frame 442, the fixed cylinder 443, the movable plate 444 and the staples 446; thus, the front end 81 and the rear end 82 on the right side are inserted 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;

[0081] Step 4: The limit adjustment cylinder 451 drives the parallel link 452 and the connecting stop lever 453 to move upward, so that the parallel link 452 and the connecting stop 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 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 assembly 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, 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;
