Description

Technical Field

[0001] This invention relates to the field of wind turbine blade recycling and processing equipment, specifically to a waste wind turbine blade recycling and dismantling device. Background Technology

[0002] Wind turbine blades are typically made of composite materials such as glass fiber and carbon fiber. The blades are generally airfoil-shaped and have excellent properties such as lightweight, high strength, and fatigue resistance. Wind turbine blades are one of the most important components of wind power generation systems. As wind turbine blades reach the end of their service life or become severely damaged, they need to be removed and replaced with new blades. Existing technologies for the treatment of waste wind turbine blades include recycling, crushing, incineration, and biodegradation. Due to the large size of wind turbine blades, the blades need to be cut into appropriate sizes according to the recycling process before crushing and other treatments.

[0003] In addition to the outer shell, wind turbine blades have at least one internal web to increase blade strength and prevent breakage. However, the addition of the web also increases the difficulty of cutting. The usual method is to use a cutting machine to cut the outer shell at multiple angles using straight and oblique cuts, and then cut off the web. It is not possible to cut the blade into segments with a single cut line. Therefore, existing cutting machines are modified and installed on the working wall of an excavator, operated by the driver. Although this method reduces the difficulty of cutting and saves manpower, the cutting efficiency is not high. Moreover, cutting outdoors will cause fiberglass debris and dust to be scattered, and contact with surrounding workers will cause skin allergies and respiratory irritation. How to improve the cutting efficiency and cutting effect of wind turbine blades is an urgent problem to be solved in the recycling of waste wind turbine blades. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a device for dismantling and reusing waste wind turbine blades.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a waste wind turbine blade recycling and dismantling device, including a pusher vehicle and a support vehicle for transporting the blades, and a dismantling device for cutting the wind turbine blades into fragments. The dismantling device includes a body, and inside the body, in the order of processing, there are a flat cutting structure, a web plate cutting structure, a clamping structure, a transverse cutting structure, a strip plate cutting structure, and a discharge conveyor belt. After the pusher vehicle and the support vehicle feed one end of the blade into the inlet on the front side of the body, the blade shell is horizontally cut along the XY plane by the flat cutting structure. The web plate cutting structure separates the web plate from the shells on both sides longitudinally along the YZ plane. After the clamping structure clamps the blade with multiple cuts, the transverse cutting structure cuts the blade into strips along the XZ plane. The strip plate cutting structure collects the strips and cuts them into blocks, which are then transported out of the body by the discharge conveyor belt.

[0006] As an improvement: the flat cutting structure includes a fixed rail seat and a movable seat, the movable seat is slidably engaged with the fixed rail seat, the movable seat is provided with a motor-driven cutting blade, the two fixed rail seats are rotatably provided with a double threaded post, and the movable seat is provided with a threaded hole that engages with the double threaded post. The flat cutting structure realizes the horizontal cutting of the blade shell.

[0007] As an improvement, the flat cutting structure also includes an adjustment structure, which includes an adjustment component and a fixed base. The adjustment component includes a hydraulic cylinder and a lifting column. The hydraulic cylinder is fixed to the fixed base and its output end is connected to the lifting column. The fixed base is provided with a grooved column that slides with the lifting column. A roller is rotatably provided on the top of the lifting column. A gear is provided on the double-threaded column. A gear is rotatably provided on the fixed base that meshes with the gear. A rack is provided on the rear side of the lifting column that meshes with the gear. The spacing of the cutting blade is automatically adjusted by the adjustment structure.

[0008] As an improvement: the web plate cutting structure includes a lifting platform, the top of which is equipped with a hydraulic cylinder 2 connected to the machine body. The lifting platform is equipped with multiple cutting blades 2 and 3 driven by a motor. The multiple cutting blades 2 and 3 are coaxially connected. The cutting blades 2 and 3 are located on both sides of the web plate, and the cutting blade 3 with a larger radius is located on the outside of the cutting blade 2. The web plate cutting structure realizes the cutting and separation of the outer shell on both sides of the web plate from the web plate.

[0009] As an improvement, the web cutting structure also includes a limiting structure. The limiting structure includes a fixed tube fixed in the machine body, a positioning rod slidingly provided at the bottom of the fixed tube, a lifting block provided at the bottom of the positioning rod, a spring provided on the outside, a roller two rotatably provided at the bottom of the lifting block, a limiting plate two provided on one side of the lifting block, and a limiting plate one that cooperates with the limiting plate two on one side of the lifting platform. The cutting feed of the cutting blade two and the cutting blade three is guaranteed by the limiting structure.

[0010] As an improvement: the clamping structure includes a fixed frame fixed inside the machine body and two clamping groups. The clamping groups are movably mounted on the slide fixed frame. Each clamping group includes a connecting frame. The connecting frame is provided with a second clamping plate. The connecting frame is hinged to the upper and lower sides of the second clamping plate with a first clamping plate. The connecting frame of the other clamping group is hinged to a third clamping plate that is offset from the first clamping plate. The clamping structure achieves fixation before transverse cutting.

[0011] As an improvement: the cross-cutting structure includes a fixed slot platform, a drive platform, a mounting platform, and a rotating arm. The drive platform is slidably disposed at the bottom of the fixed slot platform. A hydraulic cylinder three connected to the mounting platform is provided at the bottom of the drive platform. The mounting platform is hinged to the rotating arm. A cutting blade four driven by a motor is provided on the rotating arm. A fixed rod is provided on the rear side of the mounting platform. A hydraulic cylinder four is hinged on the fixed rod. The output end of the hydraulic cylinder four is hinged to the rotating arm. The cross-cutting structure realizes the cutting of the blade into small strip plates.

[0012] As an improvement: the strip plate cutting structure includes a collection platform, a conveying chamber at the bottom of the collection platform, a conveyor belt inside the conveying chamber, a pressure plate slidingly mounted at the outlet of the conveying chamber, a bevel gear one coaxially connected to the conveyor belt roller, a bevel gear two coaxially connected to the bevel gear one inside the machine body, a cam coaxially connected to the bevel gear two, the cam cooperating with the pressure plate, a hydraulic cylinder five at the outlet of the conveying chamber, a pusher at the output end of the hydraulic cylinder five, and a motor-driven cutting blade five on the front side of the pusher. The strip plate cutting structure collects the strip plate and cuts it into blocks, facilitating subsequent crushing operations and reuse.

[0013] The beneficial effects of this invention compared to existing technologies are as follows: This device greatly improves the cutting efficiency and effect of wind turbine blades. By using multiple cutting blades to cut the blades step by step into blocks, the blocks are easier to break, reducing the difficulty of breaking them and improving the recycling efficiency of waste wind turbine blades. The semi-enclosed body effectively isolates the cutting area from the outside world, preventing dust from escaping. Specifically:

[0014] 1. By using a flat-cutting structure, a web-splitting structure, and a transverse-cutting structure, the blade shell is cut into multiple parts, and the shell is separated from the web, so that the blade is cut into strips, which are then collected by the strip-cutting block structure and cut into blocks.

[0015] 2. The flat cutting structure has an adjustable structure that allows the spacing of the cutting blades to be automatically adjusted as the blade advances, preventing the moving seat from colliding with the blade due to the increase in the blade's cross-sectional area.

[0016] 3. The limiting structure of the web cutting structure automatically adjusts the limiting area, thereby controlling the movement of the lifting platform and avoiding collision between the blade cross-sectional area and the lifting platform.

[0017] 4. The clamping structure is designed with two types of clamping plates for different parts of the blade to improve the blade fixing effect and avoid the vibration of the blade during cutting by the cross-cutting structure. The cross-cutting structure improves the cutting effect through multi-directional movement design.

[0018] 5. Through the cooperation of the cam and push plate in the strip plate cutting structure, the conveyor belt moves while the cam is moving, and the cam is used to carry and hold the strip plate, so that the cutting blade can cut the strip plate into blocks. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Combined with appendix Figure 1 and attached Figure 2As shown, a waste wind turbine blade recycling and dismantling device includes a pusher 8 and a support 9 for transporting the blade 01, and a dismantling device for cutting the wind turbine blade into pieces. The dismantling device includes a body 1. Inside the body 1, in the processing sequence, there are a flat cutting structure 2, a web cutting structure 3, a clamping structure 4, a transverse cutting structure 5, a strip plate cutting structure 6, and a discharge conveyor belt 7. The pusher 8 and the support 9 feed one end of the blade 01 into the feed inlet 11 on the front side of the body 1. The flat cutting structure 2 horizontally cuts the outer shell 02 of the blade 01 along the XY plane. The web cutting structure 3 longitudinally separates the web 03 from the outer shell 02 on both sides along the YZ plane. After the clamping structure 4 clamps the multi-cut blade 01, the transverse cutting structure 5 transversely cuts the blade 01 into strips along the XZ plane. The strip plate cutting structure 6 collects the strips and cuts them into pieces, which are then conveyed out of the body 1 by the discharge conveyor belt 7.

[0038] Combined with appendix Figure 1 Appendix Figure 3 and attached Figure 4 As shown, the flat cutting structure 2 includes a fixed rail seat 21, a movable seat 22, and an adjustment structure 26. The fixed rail seat 21 and the movable seat 22 are symmetrically arranged in two sets. The fixed rail seat 21 is fixed inside the machine body 1. A slide rail 211 is provided on one side of the fixed rail seat 21, and a slide groove 221 that cooperates with the slide rail 211 is provided on one side of the movable seat 22. A cutting blade 25 and a motor 24 are provided on the movable seat 22. The motor 24 drives the cutting blade 25 to rotate through a sprocket and chain transmission structure. A double threaded post 23 is rotatably provided on the two fixed rail seats 21. The threads on both sides of the double threaded post 23 are opposite. The movable seat 22 is provided with a threaded hole that cooperates with the double threaded post 23. The adjustment structure 26 drives the double threaded post 23 to rotate, causing the two movable seats 22 to move in opposite directions, thereby controlling the distance between the two cutting blades 25.

[0039] Working principle of flat cutting structure 2: Under the drive of adjustment structure 26, double threaded column 23 rotates and engages with threaded hole on moving seat 22, so that moving seat 22 slides on fixed rail seat 21. Since the threads on both sides of double threaded column 23 are opposite, the moving seat 22 moves in the opposite direction. Motor 24 on moving seat 22 drives cutting blade 25 to rotate through sprocket and chain transmission structure. When blade 01 enters feed port 11, cutting blades 25 on both sides approach and cut blade 01, so that the outer shell 02 is horizontally cut on both sides, so that the outer shell 02 is divided into two parts. At this time, the two parts of the outer shell 02 are still connected together by internal web plate 03.

[0040] Combined with appendix Figure 3 and attached Figure 4As shown, the adjustment structure 26 includes an adjustment component 27 and a fixed base 28. The adjustment component 27 includes a hydraulic cylinder 271 and a lifting column 272. The hydraulic cylinder 271 is fixed to the fixed base 28 and its output end is connected to the lifting column 272. The fixed base 28 is provided with a connecting arm 281 that connects to the outside of the machine body 1. The fixed base 28 is provided with a groove column 282. The lifting column 272 is provided with slide rails 273 on both sides that slide with the groove column 282. The top of the lifting column 272 is provided with a roller 274 that rotates. The middle section of the double threaded column 23 is provided with a gear 231. The fixed base 28 is provided with a gear 29 that meshes with the gear 231. The rear side of the lifting column 272 is provided with a rack 275 that meshes with the gear 29.

[0041] Working principle of adjustment structure 26: When blade 01 enters the feed inlet 11, hydraulic cylinder 271 drives lifting column 272 to rise, so that roller 274 contacts the bottom of blade 01. During this process, when lifting column 272 rises, rack 275 meshes with gear 29, causing rack 275 to drive gear 29 to rotate. Through gear 29 meshing with gear 231, double threaded column 23 rotates, thereby adjusting the distance between the two cutting blades 25. During the advance of blade 01, roller 274 always remains in contact with blade 01. Roller 274 descends as blade 01 advances, thereby increasing the distance between the two cutting blades 25. That is, the distance between cutting blades 25 can increase as the cross-sectional area of ​​blade 01 increases. The adjustment of the distance between cutting blades 25 will not be adjusted too precisely according to blade 01. The adjustment deviation can be controlled within the cutting width of cutting blade 25.

[0042] Combined with appendix Figure 2 Appendix Figure 5 and attached Figure 6 As shown, the web plate slitting structure 3 has two sets, which are symmetrically arranged. Each web plate slitting structure 3 includes a lifting platform 32. A second hydraulic cylinder 31 is mounted on the top of the lifting platform 32. A first fixing plate 311, connected to the machine body 1, is mounted on the top of the second hydraulic cylinder 31. The lifting platform 32 contains a second motor 33, a drive shaft 34, and a driven shaft 35. A third gear 331 is mounted at the output end of the second motor 33, and a fourth gear 35 meshes with the third gear 331 on the drive shaft 34. 42. The drive shaft 34 and the driven shaft 35 are respectively equipped with sprocket 1 341 and sprocket 2 351. Sprocket 1 341 and sprocket 2 351 are connected by chain drive. The driven shaft 35 is equipped with multiple cutting blades 2 36 and cutting blade 37. Cutting blades 2 36 and cutting blade 37 are located on both sides of the web 03, and the cutting blade 37 with a larger radius is located outside the cutting blade 2 36. The cutting blades 2 36 and cutting blade 37 on the two sets of web cutting structures 3 are staggered in the Z direction.

[0043] Working principle of web plate cutting structure 3: Motor 2 33 drives gear 3 331 to rotate. Through the meshing of gear 3 331 and gear 4 342, the drive shaft 34 rotates. Sprockets 1 341 and sprocket 2 351 drive the driven shaft 35 to rotate. The cutting blades 2 36 and 3 37 on the driven shaft 35 rotate. The lifting platform 32 is driven by hydraulic cylinder 2 31 to perform lifting action, so that the cutting blades 2 36 and 3 37 cut the blade 01. The cutting blades 2 36 and 3 37 cut the outer shell 02 on both sides of the web plate 03, so that the web plate 03 and the outer shell 02 are separated, making it easier for the transverse cutting structure 5 to cut the outer shell 02 and the web plate 03 into strip plates.

[0044] Combined with appendix Figure 5 and attached Figure 6 As shown, the web plate splitting structure 3 also includes a limiting structure 38. The limiting structure 38 includes a fixed tube 381 fixed inside the body 1. A positioning rod 383 is slidably provided at the bottom of the fixed tube 381. A lifting block 382 is provided at the bottom of the positioning rod 383. A spring 384 is provided on the outside. The upper and lower ends of the spring 384 are respectively connected to the fixed tube 381 and the lifting block 382. A roller 385 is rotatably provided at the bottom of the lifting block 382. A limiting plate 386 is provided on one side of the lifting block 382. A limiting plate 321 that cooperates with the limiting plate 386 is provided on one side of the lifting platform 32.

[0045] Working principle of limiting structure 38: When blade 01 passes through limiting structure 38, spring 384 pushes lifting block 382 closer to blade 01, so that roller 2 385 contacts blade 01. As blade 01 enters, the cross-sectional area increases, spring 384 is compressed, lifting block 382 rises, and limiting plate 2 386 also rises. When cutting operation is required, during the descent of lifting platform 32, it is limited by limiting plate 2 386. After limiting plate 1 321 contacts limiting plate 2 386, the descent of lifting platform 32 stops. At this time, cutting blade 2 36 and cutting blade 37 have completed the cutting of blade 01. The setting of limiting structure 38 avoids excessive descent distance of lifting platform 32.

[0046] Combined with appendix Figure 2 Appendix Figure 7 Appendix Figure 8 and attached Figure 16As shown, the clamping structure 4 includes a fixed frame 41 fixed inside the machine body 1 and two sets of clamping groups 45. The fixed frame 41 includes a support frame 411 and a slide frame 412. The support frame 411 is fixed inside the machine body 1, and the bottom of the support frame 411 is connected to the slide frame 412. The slide frame 412 is equipped with a motor 42 and a double-threaded column 43. The output end of the motor 42 is equipped with a gear 421. The middle section of the double-threaded column 43 is equipped with a gear 431 that meshes with the gear 421. The threads on both sides of the double-threaded column 43 are reversed. A slider 44 is slidably mounted on the bottom of the fixed frame 41. A slider 443 is mounted on the top of the slider 44. The slider 443 is equipped with a double-threaded column 45. The threaded hole of the second column 43 is used for clamping assembly 45, which includes a slide table 451 that is slidably engaged with the fixed frame 41. A drive column 441 is provided on the rear side of the first slider 44. After the drive column 441 passes through the through hole of the slide table 451, a second spring 442 is provided. The second spring 442 is connected to the slide table 451. A connecting frame 452 is provided at the bottom of the slide table 451. A second clamping plate 454 is provided on the connecting frame 452. A first clamping plate 453 is hinged on the upper and lower sides of the second clamping plate 454 on the connecting frame 452 of another clamping assembly 45. A third clamping plate 455 is hinged on the connecting frame 452 of the other clamping assembly 45, which is offset from the first clamping plate 453. The second clamping plate 454 is located behind the gap between the first clamping plate 453 and the third clamping plate 455.

[0047] Working principle of clamping structure 4: Motor 3 42 drives gear 5 421 to rotate. Through the meshing of gear 5 421 and gear 6 431, double threaded column 2 43 rotates. Through the engagement of double threaded column 2 43 with the threaded hole on slider 2 443, slider 1 44 moves laterally within slide frame 412. Since the threads on both sides of double threaded column 2 43 are opposite, the two sliders 1 44 move in opposite directions. When slider 1 44 moves, spring 2 442 at the rear end of drive column 441 pushes slide table 451 to move laterally within slide frame 412. The clamping plate 1 453 and clamping plate 3 45... 5 or two clamping plates 454 clamp the blade 01, closing the existing cutting seam, facilitating the cutting of the transverse structure 5, and preventing the blade 01 from shaking and affecting the cutting quality. Due to the spring 442, the two clamping groups 45 apply controllable pressure to the blade 01 when clamping. The staggered clamping plates 453 and 455 allow the two clamping plates 454 to clamp the blade 01 when the cross-sectional area is small, and the clamping plates 453 and 455 to clamp the blade 01 when the cross-sectional area is large, ensuring clamping stability.

[0048] Combined with appendix Figure 2 Appendix Figure 9 Appendix Figure 10 and attached Figure 16As shown, the transverse cutting structure 5 includes a fixed slot platform 51, a drive platform 53, a mounting platform 55, and a rotating arm 57. The bottom of the fixed slot platform 51 is provided with an electrode 52 and a threaded post 521. The electrode 52 drives the threaded post 521 to rotate. The drive platform 53 slides on the bottom of the fixed slot platform 51 and is provided with a threaded hole that mates with the threaded post 521. The bottom of the drive platform 53 is provided with a hydraulic cylinder 54 that is connected to the mounting platform 55. The bottom of the drive platform 53 is provided with a positioning sleeve 531. The top of the mounting platform 55 is provided with a positioning slide rod 551 that slidably mates with the positioning sleeve 531. The mounting platform 55 is hinged to one end of the rotating arm 57. A cutting blade 58 is rotatably mounted on the other end of the rotating arm 57. A motor 56 is mounted on the mounting platform 55. The motor 56 drives the cutting blade 58 to rotate through a sprocket and chain transmission structure. A fixed rod 552 is provided on the rear side of the mounting platform 55. A hydraulic cylinder 59 is hinged on the fixed rod 552. The output end of the hydraulic cylinder 59 is hinged to the rotating arm 57.

[0049] Working principle of transverse cutting structure 5: Electrode 4 52 drives threaded post 521 to rotate. Through the engagement of threaded post 521 with threaded hole on drive platform 53, drive platform 53 moves laterally at the bottom of fixed slot platform 51. Hydraulic cylinder 3 54 realizes the lifting action of mounting platform 55, and hydraulic cylinder 4 59 realizes the rotation action of rotating arm 57. Motor 4 56 drives cutting blade 4 58 to rotate through sprocket and chain transmission structure, realizing the cutting of blade 01 by cutting blade 4 58. Under the cutting of blade 01 by flat cutting structure 2 and web plate splitting structure 3, the outer shell 02 and web plate 03 of blade 01 are cut as shown in the figure. Figure 16 The cross-section shown is strip-shaped, and the cutting blade 4 58 cuts the blade 01 into strip plates through multi-directional movement.

[0050] Combined with appendix Figure 2 Appendix Figure 11 Appendix Figure 12 and attached Figure 13 As shown, the strip-shaped plate cutting structure 6 includes a collection platform 61, a conveying chamber 611 at the bottom of the collection platform 61, a conveyor belt 62 inside the conveying chamber 611, a pressure plate 65 slidingly disposed on one side of the conveying chamber 611 at the outlet, an inclined plate disposed on the inner side of the pressure plate 65, a bevel gear 621 coaxially connected to the roller of the conveyor belt 62, a bevel gear 63 rotatably disposed inside the machine body 1 and meshing with the bevel gear 621, a cam 64 coaxially connected to the bevel gear 63, the cam 64 cooperating with the pressure plate 65, a hydraulic cylinder 66 disposed at the outlet of the conveying chamber 611, the hydraulic cylinder 66 fixed inside the machine body 1, a pusher 661 disposed at the output end of the hydraulic cylinder 66, a cutting blade 68 disposed on the front side of the pusher 661 and a motor 67 for driving the cutting blade 68 to rotate, and a discharge conveyor belt 7 disposed on one side below the pressure plate 65 and the other side extending out of the discharge port of the machine body 1.

[0051] Working principle of strip cutting structure 6: After the blade 01 is cut into strips by the transverse cutting structure 5, the strips fall into the collection platform 61 for collection. The bottom strips enter the conveying chamber 611 and are conveyed to the outlet by the conveyor belt 62 for further cutting. When the shaft of the conveyor belt 62 rotates, it drives the bevel gear 621 to rotate. Through the meshing of bevel gear 621 and bevel gear 63, the cam 64 rotates. When the protrusion of the cam 64 contacts the pressure plate 65, it pushes... The pressure plate 65 moves, pressing the strip plate at the outlet. Under the push of the hydraulic cylinder 66, the push table 661 moves forward with the cutting blade 68, cutting the strip plate into small pieces. The small pieces fall onto the discharge conveyor belt 7 for conveying. Then the conveyor belt 62 continues to rotate, causing the cam 64 to rotate and move the strip. The elasticity of the strip resets the pressure plate 65. When the subsequent strip contacts the inclined plate inside the pressure plate 65, it will also reset the pressure plate 65.

[0052] Combined with appendix Figure 1 Appendix Figure 14 and attached Figure 15 As shown, the pusher vehicle 8 includes a vehicle body 81, a fixing plate 82 for fixing the bolts of the connecting end of the blade 01 and a bracket 83 for supporting the blade 01 on the vehicle body 81. The support vehicle 9 includes a vehicle body 91, a hydraulic cylinder 92 on the vehicle body 91, a support plate 93 at the output end of the hydraulic cylinder 92, and multiple rows of arc-shaped rollers 94 rotatably arranged on the support plate 93. Optionally, the movable structure inside the machine body 1 is waterproof and dustproof (not shown). A water spray nozzle (not shown) is provided at the cutting point inside the machine body 1. A water collection structure (not shown) is provided at the bottom inner side of the machine body 1. Optionally, a fan and a connecting air duct (not shown) are connected to the rear side of the machine body 1.

[0053] In a specific implementation of this invention, the blade 01 is placed on the pusher 8 and the support 9. The blade 01 is kept horizontal by the hydraulic cylinder 92. Then, the bolts of the blade 01 mounting section are fixed to the fixing plate 82 to prevent the blade 01 from rolling. Subsequently, the blade 01 is moved to the front of the disassembly device by the pusher 8 and the support 9, while the position of the support 9 remains unchanged. The pusher 8 pushes the blade 01 towards the inlet 11. The support 9 keeps the blade 01 horizontal during the pushing process. After the blade 01 passes the inlet 11, the outer shell 02 of the blade 01 is horizontally cut along the XY plane by the flat cutting structure 2. The web plate splitting structure 3 longitudinally separates the web plate 03 from the outer shells 02 on both sides along the YZ plane. The blade 01 is then separated by a clamping structure. After clamping the multi-slot blade 01, the cross-cutting structure 5 cuts the blade 01 into strips along the XZ plane. The strip cutting structure 6 collects the strips and cuts them into blocks, which are then conveyed out of the machine body 1 by the discharge conveyor belt 7. Except for the inlet 11 and the outlet at the discharge conveyor belt 7, the machine body 1 covers the cutting area to prevent dust from spreading. A spray system or directional airflow can be installed inside to reduce dust and actively remove dust. Optionally, a slot can be opened on the rear side of the machine body 1 to increase the cutting spacing of the cross-cutting structure 5, so that long strips can be discharged from the slot on the rear side of the machine body 1. Optionally, the cutting structure and the pusher moving structure of the strip cutting structure 6 can be removed, and it can only be used for collection and conveying, with the output being strips.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
