[0045] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] The technical solutions disclosed in various embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] Please refer to Figures 1 to 17. The embodiments of the present application disclose a blade cutting device, which includes an equipment frame 100, a transmission device 200 and a cutting device 300.

[0048] The equipment frame 100 is the base for installing at least some other components of the blade cutting equipment. The conveying device 200 is a component used to convey the blades A to be cut along the conveying direction. The cutting device 300 is used to cut and decompose the blades A to be cut.

[0049] The equipment rack 100 includes a first frame 110 and a second frame 120 , which are movably connected to allow the equipment rack 100 to switch between an unfolded state and a folded state. The transmission device 200 is disposed on the first frame 110 , and the cutting device 300 is disposed on the second frame 120 .

[0050] Specifically, the first frame 110 and the second frame 120 can be rotatably connected, and the first frame 110 can rotate relative to the second frame 120. The first frame 110 can be rotated to a position in the same plane as the second frame 120 to put the equipment rack 100 in an unfolded state, or the first frame 110 can be rotated to above the second frame 120 to put the equipment rack 100 in a folded state.

[0051] Of course, the first frame 110 and the second frame 120 can also be connected by sliding or rolling. The first frame 110 and the second frame 120 can form a pull-out structure. When the equipment rack 100 is in the folded state, the first frame 110 is stacked on top of the second frame 120. When the equipment rack 100 is in the unfolded state, the first frame 110 can slide or roll relative to the second frame 120 so that the first frame 110 extends out of the second frame 120. Of course, the first frame 110 and the second frame 120 can also be connected in other ways, which will not be described in detail in the present embodiment.

[0052] When the equipment rack 100 is in the expanded state, the transmission device 200 and the cutting device 300 are spaced apart in the expanded plane of the equipment rack 100 . The transmission device 200 is used to transmit the blades A to be cut, and the cutting device 300 is used to cut the blades A to be cut.

[0053] When the equipment rack 100 is in the folded state, the transmission device 200 moves with the first frame 110 to the top of the second frame 120. When the equipment rack 100 is in the folded state, the transmission device 200 no longer transmits the blade A to be cut, and the cutting device 300 does not cut the blade A to be cut.

[0054] The blade cutting device disclosed in the embodiments of the present application comprises an equipment frame 100 configured to include a first frame 110 and a second frame 120, wherein the first frame 110 and the second frame 120 are movably connected, thereby enabling the equipment frame 100 to switch between an expanded state and a folded state. A transport device 200 is disposed on the first frame 110, and a cutting device 300 is disposed on the second frame 120. When the equipment frame 100 is in the expanded state, the transport device 200 and the cutting device 300 are spaced apart within the expanded plane of the equipment frame 100, thereby enabling the transport device 200 to transport blades A to be cut, and the cutting device 300 to cut the blades A to be cut. When the equipment frame 100 is in the folded state, the transport device 200 can rotate with the first frame 110 to above the second frame 120, thereby avoiding the problem of occupying a large space when the first frame 110 and the second frame 120 are expanded, thereby facilitating the transportation of the blade cutting device.

[0055] When the equipment rack 100 switches between the expanded state and the folded state, an operator may manually drive the first frame body 110 to move relative to the second frame body 120 or use a tool.

[0056] In another embodiment, the blade cutting device may further include a frame drive mechanism 400, which may be connected between the first frame 110 and the second frame 120. The frame drive mechanism 400 may be used to drive the first frame 110 to move relative to the second frame 120 so that the device frame 100 can switch between an unfolded state and a folded state.

[0057] The blade cutting device disclosed in the embodiment of the present application is provided with a frame drive mechanism 400, so that the frame drive mechanism 400 is connected between the first frame 110 and the second frame 120, so that the first frame 110 is driven by the frame drive mechanism 400 to move relative to the second frame 120, and the device frame 100 can be automatically switched between the unfolded state and the folded state.

[0058] Specifically, the rack drive mechanism 400 may be a fluid drive mechanism, for example, a hydraulic drive mechanism, a pneumatic drive mechanism, etc. For example, the rack drive mechanism 400 may be a hydraulic telescopic rod, a pneumatic telescopic rod, etc. The fluid drive mechanism has a certain buffering effect when driving the first frame 110 to move relative to the second frame 120, thereby preventing the first frame 110 from moving too fast relative to the second frame 120 and causing impact. Moreover, after the first frame 110 rotates into position relative to the second frame 120, the buffering effect of the fluid drive mechanism also has the effect of maintaining the first frame 110 in its current position relative to the second frame 120, thereby maintaining the equipment rack 100 in a folded state or an unfolded state.

[0059] Of course, the rack drive mechanism 400 can be a hydraulic telescopic rod, a pneumatic telescopic rod, etc. The rack drive mechanism 400 can also be a drive motor, a shape memory alloy, etc. The embodiment of the present application does not specifically limit the type of the rack drive mechanism 400.

[0060] When the equipment rack 100 is in the deployed state, in order to enable the first frame 110 to stably support the transmission device 200 and the blade A to be cut, the equipment rack 100 may optionally further include a leg 130. The leg 130 may be provided at an end of the first frame 110 facing away from the second frame 120. When the equipment rack 100 is in the deployed state, the leg 130 supports the second end of the first frame 110, and the end of the leg 130 facing away from the first frame 110 may be used for support on the ground or other fixed components.

[0061] The blade cutting equipment disclosed in the embodiment of the present application is provided with a support leg 130 at the second end of the first frame 110, so that when the equipment frame 100 is in the unfolded state, the support leg 130 can support the second end of the first frame 110, thereby enabling the first frame 110 to stably support the transmission device 200 and the blade A to be cut.

[0062] In order to stabilize the first frame 110 above the second frame 120 when the equipment rack 100 is in the folded state, the equipment rack 100 may optionally further include a locking mechanism 150, which may be provided on the second frame 120. When the equipment rack 100 is in the folded state, the locking mechanism 150 is used to lock the first frame 110 to the second frame 120, thereby making the arrangement of the first frame 110 more stable when the equipment rack 100 is in the folded state.

[0063] Specifically, the locking mechanism 150 may include a buckle, and the first frame 110 may be provided with a buckle-fitting portion. The buckle can be engaged with the buckle-fitting portion to lock the first frame 110 to the second frame 120. Of course, the locking mechanism 150 may also be a bolt, a pin, or other structure, and the embodiment of the present application does not limit the specific structure of the locking mechanism 150.

[0064] In an optional embodiment, the blade cutting device may further include a housing 600 and a column 140. The housing 600 may include a top panel 610 and two opposing side panels 620. The top panel 610 may be positioned above the second frame 120 via the column 140, and the two side panels 620 may be rotatably connected to opposite ends of the top panel 610. When the device frame 100 is in the unfolded state, the two side panels 620 may be rotated relative to the top panel 610 to a position flush with the top panel 610, with one of the two side panels 620 facing the first frame 110. When the device frame 100 is in the folded state, the two side panels 620, the top panel 610, and the second frame 120 may enclose a storage space, such that the first frame 110, the transmission device 200, and the cutting device 300 are located within the storage space.

[0065] The blade cutting device disclosed in the embodiment of the present application is provided with a shell 600 and a column 140, and the shell 600 is provided with a structure including a top plate 610 and two oppositely arranged side plates 620, so that the top plate 610 can be provided above the second frame 120 through the column 140, and the two side plates 620 can be rotatably connected to the two opposite ends of the top plate 610 respectively, so that when the equipment frame 100 is in the unfolded state, the two side plates 620 can be rotated relative to the top plate 610 to a position in the same plane as the top plate 610, and one of the two side plates 620 is opposite to the first frame 110, so that the components provided on the first frame 110 and the second frame 120 can be protected above the first frame 110 and the second frame 120. When the equipment frame 100 is in a folded state, the two side panels 620, the top panel 610 and the second frame 120 can enclose a receiving space so that the first frame 110, the transmission device 200 and the cutting device 300 are located in the receiving space, thereby making the structure of the blade cutting equipment more compact and protecting components such as the first frame 110, the transmission device 200 and the cutting device 300.

[0066] When the equipment frame 100 is in the expanded state, in order to provide a larger accommodation space for the blade A to be cut, the column 140 can optionally be a retractable column. The column 140 can be fixedly arranged on the second frame 120, and the column 140 can support and guide the top plate 610. The blade cutting equipment can also include a lifting drive 700. The lifting drive 700 can be arranged on the second frame 120 and connected to the top plate 610. When the equipment frame 100 is in the expanded state, the lifting drive 700 can drive the column 140 to extend to a first length through the top plate 610. When the equipment frame 100 is in the folded state, the lifting drive 700 can drive the column 140 to extend to a second length through the top plate 610, wherein the first length is greater than the second length.

[0067] The blade cutting device disclosed in the embodiment of the present application is provided with a lifting drive member 700 and the column 140 is provided as a retractable column, so that when the device frame 100 is in the expanded state, the lifting drive member 700 drives the column 140 to extend to a first length through the top plate 610, and when the device frame 100 is in the folded state, the lifting drive member 700 drives the column 140 to extend to a second length through the top plate 610, so that when the device frame 100 is in the expanded state, a larger accommodating space can be provided for the blade A to be cut, and when the device frame 100 is in the folded state, the overall structure of the blade cutting device can be made more compact.

[0068] When the equipment frame 100 is in a folded state, in order to better protect the transmission device 200 and the cutting device 300, optionally, the housing 600 may further include an end plate 630, and the blade cutting device may further include a control box 800. The end plate 630 and the control box 800 may be arranged relative to and spaced apart from each other on the second frame 120. The transmission device 200 and the cutting device 300 may both be connected to a control module in the control box 800. The control module may be used to control the transmission device 200 and the cutting device 300 to perform corresponding transmission and cutting operations. When the equipment frame 100 is in a folded state, the end plates 630 and the control box 800 are respectively located at the two ends of the top plate 610 connected between the two side plates 620, so that the two side plates 620, the top plate 610, the second frame 120, the end plates 630 and the control box 800 together form a storage space.

[0069] The blade cutting equipment disclosed in the embodiment of the present application sets an end plate 630 and uses the control box 800 as a part of the accommodating space, so that when the equipment frame 100 is in a folded state, the two side panels 620, the top plate 610, the second frame 120, the end plate 630 and the control box 800 together enclose the accommodating space, thereby better protecting the transmission device 200 and the cutting device 300.

[0070] In an optional embodiment, the conveying device 200 may include a first drive mechanism 210, a second drive mechanism 220, and two rotating assemblies 230. The rotating assembly 230 may include a mounting bracket 231 and a rotating body 232. The mounting bracket 231 may be mounted on the first frame 110, and the rotating body 232 may be rotatably mounted on the mounting bracket 231. A conveying space is formed between the rotating bodies 232 of the two rotating assemblies 230. The first drive mechanism 210 may be connected to the mounting bracket 231 to drive the mounting bracket 231 to move along the equipment frame 100, thereby driving the rotating bodies 232 of the two rotating assemblies 230 to clamp the blade A to be cut. The second drive mechanism 220 may be connected to the rotating body 232 to drive the rotating body 232 to rotate, thereby causing the blade A to be cut to extend along the conveying space by a predetermined length. The cutting device 300 may be used to cut the portion of the blade A to be cut that extends beyond the conveying space.

[0071] The mounting bracket 231 is mounted on the equipment frame 100. The mounting bracket 231 is movably mounted on the equipment frame 100. The mounting bracket 231 can be movably mounted on the equipment frame 100 or rotatably mounted on the equipment frame 100. A rotating body 232 is rotatably mounted on the mounting bracket 231. A conveying space is formed between the rotating bodies 232 of at least two rotating assemblies 230. The conveying device 200 conveys the blades A along the conveying direction within the conveying space, which extends along the conveying direction. The cutting device 300 is mounted on the equipment frame 100.

[0072] The first drive mechanism 210 can be mounted on the equipment frame 100, on other components of the blade cutting equipment, or independently mounted on the ground. The present embodiment does not limit the arrangement of the first drive mechanism 210. The first drive mechanism 210 is connected to the mounting bracket 231 and is configured to drive the mounting bracket 231 to move relative to the equipment frame 100, thereby driving the rotating bodies 232 of the at least two rotating assemblies 230 to clamp the blade A.

[0073] Specifically, the first driving mechanism 210 can drive the mounting brackets 231 of at least two rotating assemblies 230 to move relative to each other, so that the mounting brackets 231 of the two rotating assemblies 230 move in a direction toward or away from each other, thereby causing the mounting brackets 231 of the two rotating assemblies 230 to drive the rotating bodies 232 to move toward or away from each other. Of course, the first driving mechanism 210 can also drive the mounting brackets 231 of the two rotating assemblies 230 to rotate about their respective rotation axes, with the rotation axes of the rotating bodies 232 spaced apart from the rotation axes of the mounting brackets 231. When the first driving mechanism 210 drives the mounting brackets 231 of the two rotating assemblies 230 to rotate about their respective rotation axes, the mounting brackets 231 of the two rotating assemblies 230 drive their respective rotating bodies 232 to rotate about the rotation axes of the mounting brackets 231, so that the mounting brackets 231 of the two rotating assemblies 230 drive the rotating bodies 232 to move toward or away from each other. The first driving mechanism 210 and the second driving mechanism 220 can be a hydraulic driving mechanism, a pneumatic driving mechanism, a driving motor, etc. The embodiment of the present application does not specifically limit the types of the first driving mechanism 210 and the second driving mechanism 220.

[0074] Specifically, when the mounting bracket 231 is movably mounted on the equipment rack 100, the first drive mechanism 210 may include a linear drive motor, and each mounting bracket 231 may be correspondingly provided with a linear drive motor, which can drive the mounting bracket 231 to move. Of course, the first drive mechanism 210 may also include a rotary drive motor and a transmission mechanism, wherein the rotary shaft of the rotary drive motor can be connected to the mounting brackets 231 of at least two rotating assemblies 230 via the transmission mechanism, so that one rotary drive motor can drive the mounting brackets 231 of at least two rotating assemblies 230 to move along the equipment rack 100 via the transmission mechanism.

[0075] In the case where the mounting bracket 231 is rotatably mounted on the equipment rack 100, the first drive mechanism 210 may include a rotation drive motor. Each mounting bracket 231 may be correspondingly provided with a rotation drive motor, which can drive the mounting bracket 231 to rotate. Of course, the first drive mechanism 210 may also include only one rotation drive motor, which can drive the mounting brackets 231 of at least two rotating assemblies 230 to rotate via a transmission mechanism. Of course, the first drive mechanism 210 may also have other structures, such as a hydraulic drive mechanism, a pneumatic drive mechanism, etc., and the embodiment of the present application does not specifically limit the structure of the first drive mechanism 210.

[0076] The second driving mechanism 220 is connected to the rotating body 232. The second driving mechanism 220 is used to drive the rotating body 232 to rotate. The second driving mechanism 220 is used to drive the rotating body 232 to rotate around the rotation axis of the rotating body 232 to drive the blade A to extend a preset length along the conveying space. The cutting device 300 is used to cut the part of the blade A extending out of the conveying space.

[0077] Specifically, the second drive mechanism 220 may include multiple rotational drive motors, which may be correspondingly provided on the mounting bracket 231. The rotational drive motors may drive the corresponding rotating body 232 on the mounting bracket 231 to rotate around the rotation axis of the rotating body 232. Of course, the second drive mechanism 220 may also be a structure including a linear drive motor and a transmission mechanism (e.g., a screw mechanism), and the linear drive motor may drive the rotating body 232 to rotate around the rotation axis of the rotating body 232 through the transmission mechanism. Of course, the second drive mechanism 220 may also be other structures, such as a hydraulic drive mechanism, a pneumatic drive mechanism, etc. The embodiment of the present application does not impose any specific restrictions on the structure of the second drive mechanism 220.

[0078] During the specific working process, blade A can be placed in the conveying space by a manipulator or other auxiliary equipment. The first driving mechanism 210 drives the mounting bracket 231 to move, so as to drive the rotating body 232 of at least two rotating components 230 to clamp blade A. When blade A is in the clamping state, the second driving mechanism 220 drives the rotating body 232 to rotate, so that the rotating body 232 drives the blade A to extend along the conveying space by a preset length. After the blade A extends along the conveying space by a preset length, the cutting device 300 cuts the part of the blade A extending out of the conveying space. After the part of the blade A extending out of the conveying space is cut, the second driving mechanism 220 drives the rotating body 232 to rotate again, so that the rotating body 232 drives the blade A to extend along the conveying space by a preset length. The cutting device 300 cuts the part of the blade A extending out of the conveying space until the entire blade A is cut.

[0079] The blade cutting device disclosed in the embodiment of the present application is provided with a transmission device 200 and a cutting device 300, and the transmission device 200 is provided with a structure including a first driving mechanism 210, a second driving mechanism 220 and at least two rotating components 230, and the rotating component 230 is provided with a structure including a mounting bracket 231 and a rotating body 232, so that the mounting bracket 231 is provided on the equipment frame 100, and the rotating body 232 is rotatably provided on the mounting bracket 231, so that a conveying space is formed between the rotating bodies 232 of the at least two rotating components 230, so that when a blade A is input into the conveying space, the first driving mechanism 210 drives the mounting bracket 231 to move along the equipment frame 100 to drive the blade A to The rotating body 232 of at least two rotating assemblies 230 clamps the blade A, and then the rotating body 232 is driven to rotate by the second driving mechanism 220 to drive the blade A to extend a preset length along the conveying space. The cutting device 300 cuts the part of the blade A extending out of the conveying space. After the cutting is completed, the blade A can continue to be conveyed by the transmission device 200. Due to the use of the blade cutting device disclosed in the embodiment of the present application, there is no need to move the blade cutting device or adjust the position of the blade A through an external machine when cutting the blade A, thereby saving the time of moving the blade cutting device or adjusting the position of the blade A through an external machine, thereby improving the cutting efficiency of the blade cutting device on the blade A.

[0080] Specifically, the at least two rotating components 230 can be an even number or an odd number, and the at least two rotating components 230 can be distributed on both sides of the conveying space perpendicular to the conveying direction. For example, there can be two rotating components 230, and the two rotating components 230 can be symmetrically arranged on both sides of the conveying space. For another example, there can be three rotating components 230, one of the rotating components 230 is located on one side of the conveying space, and the other two rotating components 230 are located on the other side of the conveying space. Of course, the number of rotating components 230 can also be other numbers, and the embodiment of the present application does not impose specific restrictions on the number of rotating components 230.

[0081] It should be noted that the mounting brackets 231 of at least two rotating assemblies 230 drive the rotating bodies 232 to move closer to or away from each other, which means that the mounting brackets 231 of the rotating assemblies 230 located on the same side of the conveying space and the mounting brackets 231 of the rotating assemblies 230 located on the other side of the conveying space drive the rotating bodies 232 to move closer to or away from each other in a direction perpendicular to the conveying direction, and does not mean that the rotating bodies 232 of the rotating assemblies 230 located on the same side of the conveying space move closer to or away from each other in the conveying direction.

[0082] Each rotating assembly 230 may include a mounting bracket 231 and a rotating body 232. Of course, each rotating assembly 230 may also include multiple mounting brackets 231 and multiple rotating bodies 232, with each rotating assembly 230 having a one-to-one correspondence between the multiple mounting brackets 231 and the multiple rotating bodies 232. The multiple mounting brackets 231 of each rotating assembly 230 may be spaced apart in the conveying direction. The multiple mounting brackets 231 of at least two rotating assemblies 230 may be arranged in a one-to-one correspondence perpendicular to the conveying direction, with the rotating bodies 232 on the multiple mounting brackets 231 of at least two rotating assemblies 230 collectively enclosing a conveying space. The blade cutting device disclosed in the embodiment of the present application discloses a specific transmission device 200. A first drive mechanism 210 drives the mounting bracket 231 to move along the equipment frame 100, thereby driving the rotating bodies 232 of the two rotating assemblies 230 to clamp the blade A to be cut. A second drive mechanism 220 drives the rotating bodies 232 to rotate, causing the blade A to be cut to extend along the conveying space to a predetermined length, thereby achieving the transmission of the blade A to be cut.

[0083] Of course, the transmission device 200 may also have other structures. For example, the transmission device 200 may include a robot that can clamp and transmit the blade A to be cut. The transmission device 200 may also have other structures. The embodiment of the present application does not limit the specific structure of the transmission device 200.

[0084] In an optional embodiment, the force with which the first drive mechanism 210 drives the rotating body 232 to clamp the blade A via the mounting bracket 231 can vary according to the thickness of the blade A. For example, the first drive mechanism 210 can include a drive spring, which, under the action of an elastic force, can drive the mounting bracket 231 to drive the rotating body 232 to clamp the blade A. In areas where the blade A is thinner, the elastic force applied by the first drive mechanism 210 is smaller, and the force with which the rotating body 232 clamps the blade A is also smaller; in areas where the blade A is thicker, the elastic force applied by the first drive mechanism 210 is larger, and the force with which the rotating body 232 clamps the blade A is also larger. Providing the first drive mechanism 210 with a structure including a drive spring makes the structure of the first drive mechanism 210 relatively simple.

[0085] To ensure a more stable force exerted by the rotating body 232 to clamp the blade A, the first drive mechanism 210 may optionally be a constant pressure drive mechanism. During the process of the blade A extending to a predetermined length along the conveying space, the first drive mechanism 210, via the mounting bracket 231, drives the rotating body 232 to maintain a predetermined pressure to clamp the blade A. The predetermined pressure can be adjusted based on the actual application environment and is not limited to a specific value.

[0086] Specifically, the first drive mechanism 210 may include a drive body and a pressure sensor. The drive body may be connected to the pressure sensor, and the pressure sensor may be provided on the mounting bracket 231. When the rotating body 232 clamps the blade A, the pressure sensor may contact the surface of the blade A. The drive body may drive the mounting bracket 231 to move based on the pressure detected by the pressure sensor, so that the pressure of the pressure sensor is always maintained at a preset pressure, thereby ensuring that the force exerted by the rotating body 232 to clamp the blade A is always at the preset pressure. It should be noted that when providing the pressure sensor, the pressure detected by the pressure sensor must be equal to the force exerted by the rotating body 232 to clamp the blade A.

[0087] Of course, the first drive mechanism 210 can also be a hydraulic drive mechanism or a pneumatic drive mechanism. The fluid pressure input by the hydraulic drive mechanism or the pneumatic drive mechanism corresponds to the force applied by the rotating body 232 to clamp the blade A. During the process of the blade A extending to a preset length along the conveying space, the fluid pressure input by the hydraulic drive mechanism or the pneumatic drive mechanism can be controlled to remain constant, thereby ensuring that the force applied by the rotating body 232 to clamp the blade A is always at the preset pressure. Of course, the first drive mechanism 210 can also be other types of constant pressure drive mechanisms, and the embodiments of the present application do not specifically limit the type of the first drive mechanism 210.

[0088] The blade cutting device disclosed in the embodiment of the present application sets the first drive mechanism 210 as a constant pressure drive mechanism, so that when the blade A extends to a preset length along the conveying space, the first drive mechanism 210 drives the rotating body 232 to clamp the blade A through the mounting bracket 231, and the force of the rotating body 232 to clamp the blade A is always at a preset pressure, thereby making the force of the rotating body 232 to clamp the blade A more stable.

[0089] When the mounting bracket 231 is movably mounted on the equipment rack 100, to ensure more stable movement of the mounting bracket 231 along the equipment rack 100, the equipment rack 100 may optionally be provided with a guide rail 150, wherein the extension direction of the guide rail 150 may be perpendicular to the conveying direction of the blade A within the conveying space. The mounting bracket 231 may have a guide rail mating portion 231a, which may be mounted on the guide rail 150. The guide rail mating portion 231a may be guided and engaged with the guide rail 150 along the extension direction of the guide rail 150. The mounting bracket 231 may be moved along the equipment rack 100 by the guided engagement of the guide rail mating portion 231a with the guide rail 150, thereby driving the rotating body 232 to clamp the blade A.

[0090] The blade cutting device disclosed in the embodiment of the present application is provided with a guide rail 150 on the equipment frame 100, and a guide rail matching portion 231a is provided on the mounting bracket 231, so that the mounting bracket 231 can move along the equipment frame 100 through the guiding cooperation between the guide rail matching portion 231a and the guide rail 150, thereby making the movement of the mounting bracket 231 along the equipment frame 100 more stable, and further making the rotating body 232 more stable when clamping the blade A.

[0091] When the blade A is input into the conveying space, the bottom of the blade A can be supported on the equipment rack 100. When the blade A extends to a preset length along the conveying space, the bottom of the blade A can slide with the equipment rack 100.

[0092] To improve the smoothness of conveying the blade A within the conveying space, the transmission device 200 may optionally further include an auxiliary conveying assembly 240. The auxiliary conveying assembly 240 may include an auxiliary base 241 and an auxiliary roller 242. The auxiliary base 241 may be disposed on the equipment frame 100. The auxiliary roller 242 may be rotatably disposed on the auxiliary base 241 about a first axis, the extension direction of the first axis being perpendicular to the conveying direction of the blade A within the conveying space. The auxiliary roller 242 is configured to roll with the blade A in the conveying direction when the blade A is input into the conveying space. The auxiliary roller 242 is configured to cooperate with the bottom support of the blade A and to roll with the bottom of the blade A as the blade A extends a predetermined length along the conveying space.

[0093] The blade cutting device disclosed in the embodiment of the present application is provided with an auxiliary conveying component 240, and the auxiliary conveying component 240 is provided with a structure including an auxiliary base 241 and an auxiliary roller 242, so that the auxiliary base 241 is provided on the equipment frame 100, and the auxiliary roller 242 is rotatably provided on the auxiliary base 241 around a first axis, so that when the blade A extends a preset length along the conveying space, the auxiliary roller 242 rolls with the bottom of the blade A, which is beneficial to improving the smoothness of the conveying of the blade A in the conveying space, and can also alleviate the wear caused by the movement of the blade A.

[0094] Specifically, the auxiliary roller 242 can be arranged in the conveying space, thereby facilitating the compactness of the blade cutting device. In another embodiment, the transmission device 200 can include a first auxiliary conveying assembly 240a and a second auxiliary conveying assembly 240b. In the conveying direction, the first auxiliary conveying assembly 240a and the second auxiliary conveying assembly 240b can be respectively arranged on both sides of the conveying space.

[0095] The blade cutting device disclosed in the embodiment of the present application solves the problem that the conveying space is too small to set up a larger auxiliary conveying component 240 by arranging the first auxiliary conveying component 240a and the second auxiliary conveying component 240b on both sides of the conveying space in the conveying direction. In addition, the first auxiliary conveying component 240a and the second auxiliary conveying component 240b are respectively arranged on both sides of the conveying space, so that the span of the first auxiliary conveying component 240a and the second auxiliary conveying component 240b is larger, which is beneficial to improving the stability of the support for blade A.

[0096] In an optional embodiment, the blade cutting device may further include a detection device and a first control device. The detection device may be disposed on the device frame 100 and may be configured to detect whether the blade A extends from the conveying space by a predetermined length. The detection device and the second drive mechanism 220 are both connected to the first control device. If the detection device detects that the blade A extends from the conveying space by the predetermined length, the first control device may control the second drive mechanism 220 to stop driving the rotating body 232.

[0097] Specifically, the detection device can be a photoelectric sensor, a pressure sensor, a limit switch, etc. The embodiment of the present application does not impose any specific restrictions on the type of the detection device.

[0098] The blade cutting equipment disclosed in the embodiment of the present application is provided with a detection device and a first control device, so that during the process of blade A being transported along the conveying direction in the conveying space, the detection device can detect whether blade A extends out along the conveying space by a preset length. When it is detected that blade A extends out along the conveying space by a preset length, the first control device controls the second drive mechanism 220 to stop driving the rotating body 232 to rotate, thereby ensuring that the length of blade A extending out along the conveying space remains consistent each time blade A is transported, which is beneficial to the subsequent processing of blade A.

[0099] The movement of the mounting bracket 231 driven by the first drive mechanism 210 and the rotation of the rotating body 232 driven by the second drive mechanism 220 can both be controlled by an operator. To achieve automation of the blade cutting equipment, the blade cutting equipment can optionally further include a first control device. The first drive mechanism 210, the second drive mechanism 220, and the cutting device 300 can all be connected to the first control device. When a blade A is input into the conveying space, the first control device is used to control the first drive mechanism 210 to drive the mounting bracket 231 to move along the equipment frame 100, thereby driving the rotating bodies 232 of at least two rotating assemblies 230 to clamp the blade A. When the rotating bodies 232 of at least two rotating assemblies 230 clamp the blade A, the first control device is used to control the second drive mechanism 220 to drive the rotating body 232 to rotate, thereby driving the blade A to extend along the conveying space by a preset length. When the blade A extends along the conveying space by the preset length, the first control device is used to control the cutting device 300 to cut the portion of the blade A that extends beyond the conveying space.

[0100] The blade cutting equipment disclosed in the embodiment of the present application is provided with a control device so that the first drive mechanism 210, the second drive mechanism 220 and the cutting device 300 can all be connected to the first control device, so that the control device controls the first drive mechanism 210 to drive the mounting bracket 231 to move, and controls the second drive mechanism 220 to drive the rotating body 232 to rotate and controls the cutting device 300 to cut the part of the blade A extending out of the conveying space, thereby realizing the automation of the blade cutting equipment.

[0101] The present invention provides a specific cutting device 300, which may include an omnidirectional mobile arm 310, a lifting mechanism 320, and a cutting body 330. The lifting mechanism 320 may be disposed on the second frame 120 and connected to the omnidirectional mobile arm 310. The lifting mechanism 320 may be used to drive the omnidirectional mobile arm 310 to move upward and downward, and the omnidirectional mobile arm 310 may be connected to the cutting body 330.

[0102] It should be noted that the omnidirectional mobile robot arm 310 is a robot arm that can move freely in any direction. It can move horizontally in the forward, backward, left, right, and even rotate without changing its orientation. The structure and principles of the omnidirectional mobile robot arm 310 are already known in the art and will not be further described here.

[0103] The blade cutting equipment disclosed in the embodiment of the present application is configured such that the cutting device 300 includes an omnidirectional mobile robotic arm 310, a lifting mechanism 320 and a cutting body 330, so that the lifting mechanism 320 can drive the omnidirectional mobile robotic arm 310 to rise and fall, and the omnidirectional mobile robotic arm 310 drives the cutting body 330 to move. Thus, with the cooperation of the lifting mechanism 320 and the omnidirectional mobile robotic arm 310, the movement of the cutting body 330 is more flexible, which is beneficial to the cutting of the blade A to be cut.

[0104] Specifically, the cutting device 300 may be a water jet cutting device, and the cutting body 330 may be a water jet cutting head. The working principle of a water jet cutting device is as follows: water is pressurized to 200-400 MPa to impart enormous pressure energy to the water, which is then fed into a nozzle with a very small aperture. Abrasive is then added and mixed, and then ejected at a high speed exceeding twice the speed of sound. The cutting of the material is achieved through the erosion of the solid abrasive, the shearing effect of the water on the material, and the micro-machining effect of the abrasive on the cutting surface.

[0105] It should be noted that the specific structure and principle of the water jet cutting device are prior art and will not be further described in detail in the present embodiment. The blade cutting device disclosed in the present embodiment utilizes a water jet cutting device as the cutting device 300 and a water jet cutting head as the cutting body 330, which facilitates a smooth cut on the blade A. Furthermore, the cutting speed is fast, the noise is low, and no heat, dust, or gas is generated during the cutting process.

[0106] Of course, the cutting device 300 can also be a chain arm saw, a laser cutting device, etc., and the cutting body 330 can correspond to a chain, a laser emitting device, etc. The embodiment of the present application does not impose any specific restrictions on the type of the cutting device 300.

[0107] Of course, the cutting device 300 can also be a structure including a cutting body 330, a movable slide and a lifting slide. The movable slide can be movably arranged on the second frame 120, the lifting slide can be arranged on the movable slide, and the cutting body 330 can be arranged on the lifting slide. When the cutting device 300 cuts the blade A to be cut, the movable slide drives the lifting slide and the cutting body 330 to move a preset feed stroke each time. After the movable slide drives the lifting slide and the cutting body 330 to move the preset feed stroke, the lifting slide drives the cutting body 330 to move up and down to cut the blade A. After the cutting is completed at the current position, the movable slide drives the lifting slide and the cutting body 330 to move the preset feed stroke again. The lifting slide drives the cutting body 330 to move up and down to cut the blade A to be cut until the portion of the blade A to be cut extending along the conveying space by a preset length is cut. Of course, the cutting device 300 can also have other structures, which will not be described in detail in the embodiments of the present application.

[0108] Because blade A has an irregular structure, the cutting path varies when cutting different locations on blade A. To accurately determine the cutting path for blade A, the cutting device 300 may optionally include a scanning device 340 and a second control device. The omnidirectional mobile robotic arm 310, the lifting mechanism 320, the cutting body 330, and the scanning device 340 may all be connected to the second control device. The scanning device 340 may be used to scan the portion of blade A that extends beyond the conveying space. The second control device may determine the cutting path based on the scanning information from the scanning device 340 and control the lifting mechanism 320 and the omnidirectional mobile robotic arm 310 to drive the cutting body 330 to cut blade A along the cutting path.

[0109] Specifically, the scanning device 340 can be a visual scanning device. For example, the scanning device 340 can include a camera, which can be used to photograph and scan the portion of blade A that extends out of the conveying space, thereby determining the external features of blade A. Of course, the scanning device 340 can be a radar recognition device, which can emit electromagnetic waves (radar waves) and then receive the reflected signals, and determine the external features of blade A by analyzing the time delay and intensity of the reflected signals. The scanning information includes the external features of blade A (such as the height, thickness, curvature, and other information of the blade). The second control device can automatically obtain the cutting path for the portion of blade A that extends out of the conveying space based on the comparison of the scanning information with the preset blade information. The preset blade information (such as the height, thickness, curvature, and other information of the blade) has a preset correspondence with the cutting path and is preset in the second control device.

[0110] The blade cutting equipment disclosed in the embodiment of the present application is equipped with a scanning device 340 and a second control device, so that the scanning device 340 can scan the part of the blade A extending out of the conveying space. The second control device determines the cutting path based on the scanning information of the scanning device 340, and controls the lifting mechanism 320 and the omnidirectional mobile robotic arm 310 to drive the cutting body 330 to cut the blade A along the cutting path. The operator can improve the cutting efficiency of the cutting body 330 on the blade A by optimizing the preset cutting path.

[0111] In order to reduce the number of components of the cutting device 300, optionally, the blade cutting equipment may also include a first control device, and the scanning device 340 may be connected to the first control device. The scanning device 340 can scan the blade A during the transmission of the blade A along the conveying space. At this time, the scanning information acquired by the scanning device 340 may include the distance moved by the blade A in the conveying direction. The first control device can judge whether the blade A extends a preset length along the conveying space based on the distance moved by the blade A in the conveying direction, thereby eliminating the need to separately set up other inspection devices for detecting the length of the blade A extending along the conveying space, thereby reducing the number of components of the cutting device 300.

[0112] The cutting device 300 may be a water jet cutting device, and the cutting body 330 may be a water jet cutting head. The blade cutting apparatus may further include a wastewater collection module 900, which may include a water collection tray 910 and a wastewater tank 920. The water collection tray 910 may be used to collect wastewater generated when the water jet cutting head cuts blades A, and the wastewater tank 920 may be used to store the wastewater collected by the water collection tray 910.

[0113] It should be noted that the working principle of the water jet cutting device 300 is: water is pressurized to 200-400Mpa so that the water has huge pressure energy and is sent to a nozzle with a very small aperture, and after adding abrasive and mixing, it is ejected at a high speed of more than twice the speed of sound. The cutting of the material is achieved through the erosion effect of the solid abrasive, the shearing effect of the water on the material, and the micro-machining effect of the abrasive on the cutting surface.

[0114] The water receiving tray 910 can be provided on the equipment frame 100 and can be located below the water jet cutting head. The waste water tank 920 can be provided on the equipment frame 100 and can be connected to the water receiving tray 910 .

[0115] The waste water generated by the water jet cutting head during the process of cutting the blade A will fall into the water receiving tray 910 located below the water jet cutting head, and the water receiving tray 910 will then collect the waste water into the waste water tank 920, thereby realizing the collection of the waste water.

[0116] The blade cutting equipment disclosed in the embodiment of the present application is equipped with a water receiving tray 910 and a waste water tank 920, so that the water receiving tray 910 is located below the water jet cutting head, so that the waste water generated when the water jet cutting head cuts the blade A can be collected in the waste water tank 920 through the water receiving tray 910, thereby preventing the waste water generated by the water jet cutting head in the process of cutting the blade A from polluting the environment.

[0117] When collecting wastewater, the water tray 910 not only collects the wastewater generated by the water jet cutting head during the cutting of blade A, but also collects the waste generated by cutting blade A. If the wastewater and waste are directly discharged into the wastewater tank 920, it is easy to cause pipe blockage. To alleviate pipe blockage, the wastewater collection module 900 can optionally further include a sedimentation tank 930 and a water pump 940. The sedimentation tank 930 can be provided on the equipment rack 100, and the water tray 910, the sedimentation tank 930, the water pump 940 and the wastewater tank 920 can be connected in sequence. The sedimentation tank 930 can be a device for separating wastewater and waste.

[0118] The blade cutting equipment disclosed in the embodiment of the present application is provided with a sedimentation tank 930 and a water pump 940, so that the water receiving tray 910, the sedimentation tank 930, the water pump 940 and the wastewater tank 920 can be connected in sequence, so that the wastewater and waste material collected by the water receiving tray 910 enter the sedimentation tank 930 together. After the wastewater and waste material are separated in the sedimentation tank 930, the water pump 940 pumps the wastewater in the sedimentation tank 930 into the wastewater tank. The waste material separated in the sedimentation tank 930 can be processed regularly, thereby alleviating the blockage of the pipeline caused by the waste material, and reducing the waste material entering the water pump 940, thereby protecting the water pump 940.

[0119] In an optional embodiment, the wastewater collection module 900 may further include a first filter device 950, which may be located between the sedimentation tank 930 and the water pump 940. The first filter device 950 can filter out larger waste materials. The first filter device 950 may be a filter screen, filter cotton, or the like. The present embodiment does not impose any specific restrictions on the choice of the first filter device 950.

[0120] The blade cutting equipment disclosed in the embodiment of the present application sets a first filter device 950 between the sedimentation tank 930 and the water pump 940, so that the first filter device 950 can filter out larger waste materials, thereby preventing larger waste materials from entering the water pump 940, thereby protecting the water pump 940.

[0121] Optionally, the water tray 910 can be provided with an avoidance hole, the lifting mechanism 320 can pass through the avoidance hole and be arranged on the equipment frame 100, and the vertical projection area of ​​the water tray 910 can be greater than or equal to the vertical projection area of ​​the motion range of the water jet cutting head.

[0122] The blade cutting device disclosed in the embodiment of the present application can collect wastewater generated within the entire movement range of the water jet cutting head by setting the vertical projection area of ​​the water receiving tray 910 to be greater than or equal to the vertical projection area of ​​the water jet cutting movement range.

[0123] Specifically, the water receiving tray 910 may be funnel-shaped, so that wastewater can be collected in the central area and then flow into the wastewater tank 920 or the sedimentation tank 930 , thereby preventing wastewater from flowing out from the edge of the water receiving tray 910 .

[0124] Of course, the water receiving tray 910 may also be a tray-shaped structure or other structures, and the embodiment of the present application does not impose any specific restrictions on the structure of the water receiving tray 910.

[0125] In another embodiment, the wastewater collection module 900 may further include a water tray drive mechanism, which may be disposed on the equipment frame 100 and connected to the water tray 910. The water tray drive mechanism may drive the water tray 910 to move according to the motion path of the water jet cutting head, so that the vertical projection of the water jet cutting head always lies within the vertical projection of the water tray 910. The vertical projection area of ​​the water tray 910 may be smaller than the vertical projection area of ​​the motion range of the water jet cutting head.

[0126] The blade cutting device disclosed in the embodiment of the present application is connected to the water receiving tray 910 by setting a water receiving tray driving mechanism, so that the water receiving tray driving mechanism can drive the water receiving tray 910 to move according to the movement path of the water jet cutting head, so that the projection of the water jet cutting head in the vertical direction is always located within the projection of the water receiving tray 910 in the vertical direction, thereby allowing the water receiving tray 910 to be set relatively small, which is conducive to the miniaturized design of the wastewater collection module 900.

[0127] Optionally, the blade cutting equipment may further include a second filtering device 970. The second filtering device 970 may be arranged on the equipment frame 100 and located above the water receiving tray 910. The second filtering device 970 may be used to filter the waste of blade A generated by the water jet cutting head during the process of cutting blade A, thereby reducing the waste falling onto the water receiving tray 910, and further alleviating the problem of waste entering the pipe below the water receiving tray 910 and causing blockage in the pipe.

[0128] Specifically, the second filter device 970 can be a filter net, filter cotton, etc.

[0129] Optionally, the second filter device 970 may include a filter bracket 971, a conveyor roller driver 972, and a plurality of conveyor rollers 973. The plurality of conveyor rollers 973 may be arranged in a sequentially spaced arrangement and rotatably mounted on the filter bracket 971. The rotation axes of the plurality of conveyor rollers 973 are parallel, and the gaps between the plurality of conveyor rollers 973 may be used to allow wastewater generated by the water jet cutting head during the process of cutting blades A to flow into the water receiving tray 910. The conveyor roller driver 972 may be connected to the plurality of conveyor rollers 973 to drive the plurality of conveyor rollers 973 to rotate, so that the plurality of conveyor rollers 973 convey the waste material of blades A generated by the water jet cutting head during the process of cutting blades A to outside the blade cutting device.

[0130] The blade cutting device disclosed in the embodiment of the present application is configured such that the second filter device 970 is configured to include a filter bracket 971, a conveying roller driving member 972 and a plurality of conveying rollers 973, so that the gaps between the plurality of conveying rollers 973 allow the waste water generated by the water jet cutting head during the process of cutting blade A to flow into the water receiving tray 910, and the conveying roller driving member 972 drives the plurality of conveying rollers 973 to rotate so that the plurality of conveying rollers 973 convey the waste of blade A generated by the water jet cutting head during the process of cutting blade A to the outside of the blade cutting device, thereby avoiding the accumulation of waste on the plurality of conveying rollers 973, and further facilitating the smooth flow of waste water into the water receiving tray 910.

[0131] Since blade A is large in size, the environmental wind direction and wind force will affect the stability of blade A on the blade cutting equipment. In order to detect the environmental wind direction and wind force in real time, the blade cutting equipment can optionally be equipped with a meteorological instrument 500. The meteorological instrument 500 can be installed on the equipment frame 100. The meteorological instrument 500 can be used to detect the wind direction and wind force of the environment in which the blade cutting equipment is located, so that the environmental wind direction and wind force can be detected in real time, and then when the environmental wind direction and wind force have a greater impact on blade A installed on the blade cutting equipment, the relevant operations can be stopped immediately.

[0132] Referring to FIG. 1 to FIG. 17 , an embodiment of the present application discloses a blade cutting method. The disclosed blade cutting method is performed based on a blade cutting device having a conveying space. The disclosed method includes:

[0133] S101 , conveying the blade A so that the blade A extends along the conveying space to a preset length.

[0134] It should be noted that the blades A can be transported through the transmission device 200 of the blade cutting equipment.

[0135] S102 , scanning the output portion of the blade A extending out of the conveying space, and acquiring scanning information.

[0136] Specifically, the scanning information may include external characteristic information of the blade A (such as the height, overall thickness, curvature, etc. of the blade).

[0137] S103: Determine a cutting path for the output part according to the scanning information.

[0138] It should be noted that the blade cutting equipment can be preset with preset blade information (such as the blade's height, overall thickness, curvature, etc.). Based on the comparison of the scanning information with the preset blade information, the cutting path of the part of blade A extending out of the conveying space can be automatically obtained.

[0139] S104, cutting the output portion along the cutting path.

[0140] The blade cutting method disclosed in the embodiments of the present application conveys a blade A so that it extends a preset length along a conveying space, scans the portion of the blade A extending beyond the conveying space, and obtains scanning information. Based on the scanning information, a cutting path for the portion of the blade A extending beyond the conveying space can be automatically determined, and the portion can then be cut along the cutting path. Because the conveying, scanning, and cutting of the blade A are all automated, blade cutting efficiency can be effectively improved.

[0141] Optionally, the disclosed blade cutting device includes an equipment frame 100 , a transmission device 200 and a cutting device 300 .

[0142] The equipment frame 100 is the base for installing at least some other components of the blade cutting equipment. The transmission device 200 is a component used to transmit the blade A along the conveying direction. The cutting device 300 is used to cut and decompose the blade A.

[0143] The transport device 200 is mounted on the equipment frame 100 and defines a transport space within which the blade A can be transported. The cutting device 300 includes a drive module 311, a cutting body 320, and a scanning device 330. The drive module 311 is mounted on the equipment frame 100, and the cutting body 320 is connected to the drive module 311. The drive module 311 can drive the cutting body 320 to cut the output portion of the blade A.

[0144] The drive module 311 may include an omnidirectional mobile arm and a lifting mechanism. The omnidirectional mobile arm may be located on the lifting mechanism, and the cutting body 320 may be located on the omnidirectional mobile arm. The lifting mechanism may drive the cutting body 320 up and down via the omnidirectional mobile arm. The omnidirectional mobile arm 310 is a type of arm that can move freely in any direction, and can achieve horizontal forward, backward, left, and right movement, and even rotation, without changing its orientation. Of course, the drive module 311 may also be a structure that combines a movable slide and a lifting slide, and the present embodiment does not limit the structure of the drive module 311.

[0145] The cutting body 320 can be a water jet cutting device, or a chain arm saw, a laser cutting device, etc. The embodiment of the present application does not limit the type of the cutting body 320.

[0146] The scanning device 330 can scan the portion of the blade A extending along the conveying space. The scanning device 330 can be a visual scanning device. For example, the scanning device 330 can include a camera, which can be used to photograph and scan the portion of the blade A extending out of the conveying space, thereby determining the external characteristics of the blade A. Of course, the scanning device 330 can be a radar recognition device, which can emit electromagnetic waves (radar waves) and then receive reflected signals. The external characteristics of the blade A are determined by analyzing the time delay and intensity of the reflected signals. The scanning information includes external characteristic information of the blade A (such as the height, overall thickness, curvature, etc. of the blade).

[0147] The disclosed method includes:

[0148] S201 , controlling the conveying device 200 to convey the blade A so that the blade A extends along the conveying space by a preset length.

[0149] S202 : Control the scanning device 330 to scan the output portion of the blade A extending out of the conveying space and obtain scanning information.

[0150] Specifically, the scanning information may include external characteristic information of the blade A (such as the height, overall thickness, curvature, etc. of the blade).

[0151] S203: Determine a cutting path for the output part according to the scanning information.

[0152] It should be noted that the blade cutting equipment can be preset with preset blade information (such as the blade's height, overall thickness, curvature, etc.). Based on the comparison of the scanning information with the preset blade information, the cutting path of the part of blade A extending out of the conveying space can be automatically obtained.

[0153] S204 , controlling the driving module 311 to drive the cutting body 320 to cut the output portion along the cutting path.

[0154] The blade cutting method disclosed in the embodiment of the present application controls the conveying device 200 to convey blade A so that blade A extends a preset length along the conveying space, allowing the scanning device 330 to scan the output portion of blade A extending from the conveying space and obtain scanning information. Based on a comparison of the scanning information with preset blade information, a cutting path for the portion of blade A extending from the conveying space is automatically obtained. Furthermore, the driving module 311 is controlled to drive the cutting body 320 to cut the output portion along the cutting path. Because the blade cutting device automatically performs the conveying, scanning, and cutting of blade A, the efficiency of the blade cutting device in cutting blade A can be effectively improved.

[0155] In an optional embodiment, the cutting device 300 may further include a distance measuring module 360. The distance measuring module 360 ​​may be provided on the cutting body 320 and may be used to measure the actual distance between the cutting body 320 and the blade. The cutting body 320 is a water jet cutting head. The specific structure and principle of the water jet cutting head are related to the prior art and will not be further described in this embodiment.

[0156] In the process of controlling the driving module 311 to drive the cutting body 320 to cut the output portion along the cutting path, the disclosed method may further include:

[0157] S301 , obtaining the actual distance between the cutting body 320 and the blade A measured by the distance measurement module 360 ​​.

[0158] It should be noted that the distance measuring module 360 ​​can measure the actual distance between the cutting body 320 and the blade A in real time. The distance measuring module 360 ​​can be a laser distance measuring module or a radar distance measuring module. The embodiment of the present application does not specifically limit the type of the distance measuring module 360.

[0159] S302 , controlling the driving module 311 to adjust the actual distance between the cutting body 320 and the blade A to be within a preset distance range.

[0160] According to the actual distance between the cutting body 320 and the blade A measured by the ranging module 360, the driving module 311 can adjust the actual distance between the cutting body 320 and the blade A to be within the preset distance range, thereby avoiding problems such as poor cutting efficiency or uneven incision caused by the actual distance between the cutting body 320 and the blade A being too large or too small.

[0161] Optionally, the cutting device 300 may further include a pressure detection module 350, which may be provided on the cutting body 320. The cutting body 320 may be a water jet cutting head. The pressure detection module 350 may be used to contact the blade A and detect the contact pressure between the pressure detection module 350 and the blade A.

[0162] In the process of controlling the driving module 311 to drive the cutting body 320 to cut the output portion along the cutting path, the method may further include:

[0163] Step A1: Acquire the contact pressure between the pressure detection module 350 and the blade A.

[0164] It should be noted that, while the cutting body 320 is cutting the output portion along the cutting path, the pressure detection module 350 can move along with the cutting body 320, and the pressure detection end of the pressure detection module 350 can contact the blade A, thereby obtaining the contact pressure between the pressure detection module 350 and the blade A. After obtaining the contact pressure between the pressure detection module 350 and the blade A, the actual distance between the cutting body 320 and the blade A can be correspondingly determined.

[0165] Step A2: controlling the driving module 311 to adjust the contact pressure between the pressure detection module 350 and the blade A to be within a preset pressure range.

[0166] It should be noted that when the control driving module 311 adjusts the contact pressure between the pressure detection module 350 and the blade A to be within the preset pressure range, it also means that the actual distance between the cutting body 320 and the blade A is within the preset distance range.

[0167] The method disclosed in the embodiment of the present application adjusts the contact pressure between the pressure detection module 350 and the blade A to be within a preset pressure range by controlling the driving module 311, so that the actual distance between the cutting body 320 and the blade A is within a preset distance range, thereby avoiding problems such as poor cutting efficiency or uneven incision caused by the actual distance between the cutting body 320 and the blade A being too large or too small.

[0168] In an optional embodiment, after determining the cutting path of the output portion according to the scanning information, the method may further include:

[0169] Step B1: determining the cutting thickness information of the output portion on the cutting path according to the scanning information.

[0170] It should be noted that blade A comprises two curved side panels A1, a first inner panel A2, and a second inner panel A3. The two curved side panels A1 enclose an inner cavity, within which the first and second inner panels A2 and A3 are located. The first and second inner panels A2 and A3 are connected between the two curved side panels A1 and spaced apart. The cutting thickness information refers to the thickness of the curved side panels A1, the first and second inner panels A2 and A3.

[0171] Step B2: determining a cutting speed for cutting the output portion along the cutting path according to the cutting thickness information.

[0172] It should be noted that after the cutting thickness information of the output part on the cutting path is determined based on the scanning information, it can be compared with the preset cutting thickness information, so that the cutting speed of the cutting body 320 corresponding to the cutting thickness information when cutting along the cutting path can be automatically obtained. When the cutting body 320 cuts different thickness areas of the blade A, its corresponding cutting speed is also different. For example, in the area where the thickness of the blade A is thicker, the cutting speed of the cutting body 320 is lower, so that the thicker area of ​​the blade A can be fully cut. In the area where the thickness of the blade A is thinner, cutting is relatively easy, so that the cutting speed of the cutting body 320 can be increased. By optimizing the moving speed of the cutting body 320, the cutting effect and efficiency of the blade A can be improved. The cutting speed refers to the speed at which the cutting body 320 moves along the cutting path.

[0173] The method disclosed in the embodiment of the present application determines the cutting thickness information of the output part on the cutting path based on the scanning information, so that the cutting speed of the cutting body 320 can be determined based on the cutting thickness information, so that in the process of controlling the driving module 311 to drive the cutting body 320 to cut the output part along the cutting path, the driving module 311 can be controlled to drive the cutting body 320 to cut the output part. By optimizing the moving speed of the cutting body 320, the cutting effect and efficiency of the blade A can be improved.

[0174] In an optional embodiment, controlling the conveying device 200 to convey the blade A so that the blade A extends along the conveying space by a preset length includes:

[0175] Step C1 , controlling the transmission device 200 to transport the blade A.

[0176] Step C2: Control the scanning device 330 to detect the actual length of the blade A extending out of the conveying space.

[0177] It should be noted that, when acquiring the scanning information, the scanning device 330 may scan the blade A while the transmission device 200 is transporting the blade A, or may scan the blade A after the transmission device 200 has completed transporting the blade A.

[0178] When the scanning device 330 scans blade A to obtain scanning information during the process of blade A being transported by the transmission device 200, the scanning speed of the scanning device 330 can be adapted to the transport speed of blade A, that is, the distance that blade A is transported is equal to the distance that the scanning device 330 scans blade A during the same time. Therefore, the scanning information obtained by the scanning device 330 when scanning blade A during the process of blade A being transported by the transmission device 200 may include the actual length of blade A transported.

[0179] When the transmission device 200 scans the blade A to obtain scanning information after completing the transmission of the blade A, the scanning device 330 can scan the blade A in the transmission direction of the blade A during the process of the transmission device 200 transmitting the blade A to obtain the actual length of the blade A extending out of the transmission space.

[0180] Step C3: When the actual length is equal to the preset length, the conveying device 200 is controlled to stop conveying the blade A, so that the blade A extends along the conveying space by the preset length.

[0181] The method disclosed in the embodiment of the present application controls the scanning device 330 to detect the actual length of the blade A extending out of the conveying space, so that the scanning device 330 can not only be used to obtain scanning information, but also can detect the actual length of the blade A extending out of the conveying space, so that the scanning device 330 can serve two purposes. When the actual length is equal to the preset length, the transmission device 200 is controlled to stop conveying the blade A, so that the blade A extends along the conveying space by the preset length, thereby making the length of the blade A extending along the conveying space more accurate.

[0182] In order to improve the cutting efficiency of blade A, optionally, there can be two cutting devices 300, and the two cutting devices 300 can be located on both sides of the conveying space in a conveying direction perpendicular to the conveying space, and the scanning device 330 can be provided on the cutting body 320, and each cutting body 320 can be provided with a scanning device 330.

[0183] Controlling the scanning device 330 to scan the output portion of the blade A extending out of the conveying space includes:

[0184] In step D1 , the driving module 311 is controlled to drive the scanning device 330 to scan the side of the blade A facing the corresponding scanning device 330 .

[0185] The method disclosed in the embodiment of the present application drives the scanning device 330 to scan the side of the blade A facing the corresponding scanning device 330 by controlling the driving module 311, so that the two scanning devices 330 can scan both sides of the blade A at the same time, and the two cutting bodies 320 can cut both sides of the blade A at the same time, thereby improving the scanning and cutting efficiency of the blade A.

[0186] Of course, the cutting device 300 can also be one, and the driving module 311 drives the scanning device 330 to scan the blade A in a direction surrounding the blade A, and the driving module 311 drives the cutting body 320 to cut the blade A in the surrounding direction.

[0187] Optionally, the control driving module 311 drives the scanning device 330 to scan the side of the blade A facing the corresponding scanning device 330, including:

[0188] In step E1 , the driving module 311 is controlled to drive the scanning device 330 to move upward and downward, so as to scan the side of the scanning device 330 corresponding to the direction of the blade A.

[0189] It should be noted that the scanning device 330 can scan the blade A while the transmission device 200 is transporting the blade A. The scanning device 330 only needs to perform lifting movements and does not need to move in the transmission direction.

[0190] The method disclosed in the embodiment of the present application controls the driving module 311 to drive the scanning device 330 to move up and down, so as to scan the side of the scanning device 330 corresponding to the direction of the blade A, so that the moving distance of the scanning device 330 is relatively short.

[0191] Specifically, the scanning device 330 may include a visual sensor.

[0192] The control scanning device 330 scans the output portion of the blade A extending out of the conveying space, and obtains scanning information including:

[0193] Step F1: Control the visual sensor to scan the output part and obtain scanning information.

[0194] The method disclosed in the embodiment of the present application uses a visual sensor to scan the output part, and the method of obtaining scanning information is beneficial to the accuracy of the scanning information.

[0195] In another embodiment, scanning device 330 may include radar.

[0196] The control scanning device 330 scans the output portion of the blade A extending out of the conveying space, and obtains scanning information including:

[0197] Step G1: Control the radar to scan the output part and obtain scanning information.

[0198] The method disclosed in the embodiment of the present application uses a radar to scan the output part and obtain scanning information, so that the structure of the cutting device 300 is relatively simple.

[0199] Specifically, the cutting body 320 is a water jet cutting head.

[0200] The working principle of the water jet cutting head is to pressurize water to 200-400Mpa so that the water has huge pressure energy and is sent to a nozzle with a very small aperture. After adding abrasive and mixing, it is ejected at a high speed of more than twice the speed of sound. The cutting of the material is achieved through the erosion effect of solid abrasive, the shearing effect of water on the material, and the micro-machining effect of the abrasive on the cutting surface.

[0201] The method disclosed in the embodiment of the present application is beneficial to the smoothing of the cut of the blade A by setting the cutting body 320 as a water jet cutting head structure, and has a fast cutting speed, low noise, and no heat, dust, or gas is generated during the cutting process.

[0202] In an optional embodiment, blade A includes two curved side panels A1, a first inner panel A2 and a second inner panel A3. The two curved side panels A1 can form an inner cavity. The first inner panel A2 and the second inner panel A3 can be arranged in the inner cavity. The first inner panel A2 and the second inner panel A3 can be connected between the two curved side panels A1 and arranged at intervals. The cutting of blade A is performed based on a cutting device 300. There can be two cutting devices, and the two cutting devices 300 can be located on both sides of the two curved side panels A1 respectively.

[0203] Determining the cutting path of the output part based on the scan information includes:

[0204] Step H1, determining a first cutting route, a second cutting route, a third cutting route, a fourth cutting route and a fifth cutting route according to the scanning information, wherein the cutting path includes the first cutting route, the second cutting route, the third cutting route, the fourth cutting route and the fifth cutting route.

[0205] Cutting of the output part along the cutting path, including:

[0206] Step H2: cutting the portion of the corresponding side of the blade A along the first cutting route, the second cutting route, the third cutting route, the fourth cutting route and the fifth cutting route in sequence.

[0207] The first cutting route is a route extending along the curved side panel A1 in the first direction and located on the side of the first inner panel A2 facing away from the second inner panel A3. The second cutting route is a route extending along the curved side panel A1 in the first direction and located on the side of the second inner panel A3 facing away from the first inner panel A2. The third cutting route is a route extending along the first inner panel A2 in the first direction and located at the end of the first inner panel A2. The fourth cutting route is a route extending along the second inner panel A3 in the first direction and located at the end of the second inner panel A3. The first direction may be the conveying direction of the blade A by the conveying device 200. The fifth cutting route is a route extending along the second direction and connecting the tail of the first cutting route, the tail of the second cutting route, the tail of the third cutting route, and the tail of the fourth cutting route. The tail of the cutting route refers to the tail of the moving path when cutting the blade A along the cutting route.

[0208] The method disclosed in the embodiment of the present application decomposes the cutting path into a first cutting route, a second cutting route, a third cutting route, a fourth cutting route and a fifth cutting route, so that the driving module 311 drives the cutting body 320 to cut the part of the corresponding side of the blade A along the first cutting route, the second cutting route, the third cutting route and the fourth cutting route in sequence. After the cut part of the blade A is not fallen off, the cutting body 320 is driven to cut the blade A along the fifth cutting route, so that the cut part of the blade A can fall off together.

[0209] In order to solve the technical problems in the related technologies regarding the resource utilization of retired wind turbine blades, such as high disposal cost, poor compatibility, low work efficiency, poor safety, and inability to ensure high-value recovery of glass fiber, the present application provides a processing device for discarded wind turbine blades, which can achieve high-value recovery of glass fiber.

[0210] Figure 18 is a block diagram of a device for processing discarded wind turbine blades provided in an embodiment of the present application; Figure 19 is a block diagram of a smoldering system provided in an embodiment of the present application.

[0211] In some exemplary embodiments, as shown in FIG. 18 and FIG. 19 , a device for processing discarded wind turbine blades is provided, which is used to process discarded wind turbine blades and recycle them, thereby improving resource utilization.

[0212] The device for processing waste fan blades includes a crushing mechanism 1, a pyrolysis rotary kiln 2, a smoldering system 3, an oil recovery system 4 and an exhaust gas treatment system 5.

[0213] Before shredding, discarded wind turbine blades can be loaded into a robotic arm and cut by a cutting arm, such as a mobile, automated wind turbine blade cutting device mounted on a vehicle. Cross-cutting and longitudinal slicing are used to cut the entire discarded wind turbine blade into blade blocks, achieving initial crushing and appropriately reducing the size of the raw material for subsequent processing. The blade blocks can be, for example, but not limited to, 30 cm x 30 cm for easy crushing.

[0214] The cutting program can be set in advance to facilitate automatic positioning and cutting, and realize automated operation. The cutting method mainly adopts high-pressure water jet cutting, which effectively improves the cutting accuracy. The structural performance of the waste fan blade cut will not be changed. The cutting surface is smooth, and it is easy to achieve remote independent operation, which is more flexible and safer.

[0215] The cut waste fan blades are fed into a crushing mechanism 1, which is, for example, a shredder. The crushing mechanism 1 is used to crush the waste fan blades to obtain fragments of about 50 mm in size for pyrolysis recovery. The crushing mechanism 1 can be, for example, a double-shaft shredder or a single-shaft crusher, so as to decompose the waste fan blades into smaller particles for subsequent processing and recycling. The crushing mechanism 1 can reduce the volume of the waste fan blades, reduce the storage and processing costs of the waste fan blades, and can also separate the recyclable materials in the waste fan blades, facilitating resource recovery and reuse.

[0216] In some examples, as shown in Figures 18 and 19, a feeding device 6 is provided, and the waste fan blades in the crushing mechanism 1 are transported to the pyrolysis rotary kiln 2 through the feeding device 6 for easy decomposition. Of course, other methods of transportation can also be adopted, and the specific method will be determined according to the actual situation.

[0217] The pyrolysis rotary kiln 2 is connected to the crushing mechanism 1, and pyrolysis treatment is performed on the crushed waste fan blades. The pyrolysis rotary kiln 2 is a rotary type, which can be heated in sections to decompose the waste fan blades to different degrees. The waste fan blades are mainly made of high molecular polymers and balsa wood materials. The high molecular polymers are mainly epoxy resins and PVC (Polyvinyl Chloride, abbreviated as PVC). The pyrolysis temperature of the first section is, for example, 200°C-300°C, so that PVC can be thermally decomposed preferentially. The pyrolysis temperature of the second section is, for example, 450°C-500°C, so as to thermally decompose the epoxy resin and carry out the carbonization process of the balsa wood, so as to avoid the problem of heating to above 450°C to bring load to the subsequent exhaust treatment and possible poor treatment effect.

[0218] In this embodiment, as shown in Figures 18 and 19, an inert gas, such as nitrogen, is introduced into the pyrolysis rotary kiln 2. This provides an oxygen-deficient or oxygen-free environment, thereby preventing the risk of fire or flash explosion during the heating process and ensuring safe and stable operation of the equipment. The oxygen content can be controlled within 4%, preventing internal explosions and reducing safety risks.

[0219] The heating method of the pyrolysis rotary kiln 2 can be electromagnetic heating, for example, to achieve precise temperature control and heating speed, thereby improving conversion efficiency. Alternatively, the heating method can also be resistance heating or gas heating, etc., depending on the actual situation.

[0220] The rotary pyrolysis equipment allows the materials in the kiln to be heated more evenly, while avoiding deformation of the kiln body due to uneven heating.

[0221] Smoldering system 3 is connected to pyrolysis rotary kiln 2 to facilitate smoldering and carbon removal of the solid material after pyrolysis of the waste fan blades. The glass fibers from the pyrolysis of the waste fan blades are coated with a layer of pyrolytic carbon. In this application, smoldering system 3 is used to remove carbon, restoring the black glass fibers to their original color, ensuring high-value utilization of the glass fibers and maintaining significant performance degradation.

[0222] In some examples, as shown in Figures 18 and 19, the smoldering system 3 includes a smoldering carbon removal furnace 31, a gas delivery unit 32, and a delivery unit 33. The smoldering carbon removal furnace 31 has a feed end and a discharge end, both of which are connected to a delivery unit 33. The solid material produced by the pyrolysis of the waste fan blades enters the smoldering carbon removal furnace 31 through the feed end, undergoes smoldering treatment, and is discharged from the discharge end after completion.

[0223] The conveying portion 33 is, for example, a screw conveyor with good sealing properties, preventing the glass fibers from being exposed to the environment for a long time and thus causing harm to the human body. The conveying portion 33 rotates at a constant speed through the spiral blades, driving the material generated by the waste fan blades forward, thereby achieving uniform material transportation.

[0224] The solid material after pyrolysis is transported to the smoldering carbon removal furnace 31. The smoldering carbon removal furnace 31 does not require external pyrolysis. It uses the temperature of the solid material after pyrolysis and the gas transported by the gas transport unit 32, based on the porous medium properties of glass fiber, to achieve a flameless, slow and low-temperature combustion process.

[0225] Since the oxidation of pyrolytic carbon is an exothermic process, the smoldering process requires less energy input than the pyrolysis process. When thermal equilibrium is reached, the heat released by the oxidation of pyrolytic carbon can be used to achieve a self-sustaining combustion effect of the solid material.

[0226] The gas delivery unit 32 is connected to the smoldering carbon removal furnace 31 and is used to provide air. The gas delivery unit 32 includes, for example, a gas distributor 321, a mass flow meter 322, and a gas supply unit 323. The gas supply unit 323 includes, for example, a gas storage tank and an air compressor. The gas supply unit 321 is connected to the gas distributor 321 via the mass flow meter 322, and the gas distributor 321 is connected to the smoldering carbon removal furnace 31.

[0227] The mass flowmeter 322 precisely controls the gas flow rate to ensure proper smoldering. If the gas flow rate is too low, the contact area between oxygen and the material will be reduced, resulting in a lower smoldering degree and insufficient heat loss to offset the heat loss. If the gas flow rate is too high, the high-temperature flue gas generated by the reaction will quickly pass through the unburned area of ​​the material and preheat, resulting in heat loss. The gas flow rate delivered by the gas delivery unit 32 can be controlled at, for example, 5 cm / s to ensure proper self-sustaining smoldering.

[0228] The gas distributor 321 can make the air in the smoldering carbon removal furnace 31 more uniform, so as to ensure that the smoldering is fully carried out and improve the disposal efficiency.

[0229] In this embodiment, as shown in Figures 18 and 19, a temperature sensor 34 is provided in the smoldering carbon removal furnace 31. The temperature sensor 34 monitors the material temperature in real time to facilitate control of the feeding and discharging speeds. To achieve continuous feeding and discharging, the smoldering carbon removal furnace 31 must maintain a certain temperature and cannot completely discharge the material to prevent temperature loss. The higher the temperature, the better the smoldering degree. Due to the low temperature within the smoldering carbon removal furnace 31, the performance of the glass fiber does not significantly decline.

[0230] In this embodiment, as shown in Figures 18 and 19, the waste fan blade processing apparatus further includes a cooling device 7, which is connected to the smoldering system 3. After the waste fan blades are decarbonized by the smoldering decarbonization furnace 31, the glass fibers are transported to the cooling device 7, where they are cooled by indirect heat exchange to below 40°C, resulting in clean glass fibers. This ensures the performance of the glass fibers and enables resource recovery.

[0231] Cooling device 7 includes, for example, a cooling cylinder (not shown), a transmission device (not shown), a roller assembly (not shown), a wheel block assembly (not shown), and a sealing device (not shown). External cooling water indirectly exchanges heat with the material through the cooling cylinder wall, supplemented by a squeegee plate within the cooling cylinder to enhance radiative heat transfer. The cooling cylinder speed is adjustable, thereby achieving material cooling. Cooling device 7 is primarily used for rapid cooling of the material after pyrolysis, meeting safety and process requirements.

[0232] In this embodiment, as shown in Figures 18 and 19, the oil recovery system 4 is connected to the pyrolysis rotary kiln 2 to obtain liquid recovered oil. The recovered oil has a certain calorific value and can be burned to provide heat or upgraded to obtain chemical substances that can be resold, thus achieving resource recycling.

[0233] In some examples, as shown in Figures 18 and 19, the oil recovery system 4 includes a dust collector 41 and a condensing device 42 connected to the dust collector 41. The dust collector 41 is connected to the pyrolysis rotary kiln 2, and the condensing device 42 is connected to the exhaust gas treatment system 5.

[0234] The dust collector 41 is a dust removal device that makes the dust-laden airflow rotate, separates dust particles from the airflow by centrifugal force, and captures them on the wall of the device, and then uses gravity to make the dust particles fall into the ash hopper for dust recovery.

[0235] After the waste fan blades are pyrolyzed in the pyrolysis rotary kiln 2, the fraction gas consists of epoxy resin decomposition products and dust. The dust is removed by the dust collector 41 to improve the cleanliness. The waste fan blades are condensed into liquid by the condensation device 42 to obtain liquid recovered oil.

[0236] Among them, the condensation equipment 42 includes, for example, a spray tower (not shown in the figure), a pressure relief system (not shown in the figure), a spray system (not shown in the figure), and a maintenance platform (not shown in the figure). The mixed gas produced by pyrolysis is rapidly cooled in the spray tower, and the liquid phase (pyrolysis oil) is separated after cooling.

[0237] In this embodiment, as shown in FIG. 18 and FIG. 19 , the exhaust gas treatment system 5 is connected to any one of the smoldering system 3 , the oil recovery system 4 , and the pyrolysis rotary kiln 2 to treat the exhaust gas and avoid polluting the natural environment.

[0238] In some examples, the exhaust gas treatment system 5 includes an alkaline cleaning device 51 , a demisting device 52 and an adsorption unit 53 , and the alkaline cleaning device 51 is connected to the adsorption unit 53 through the demisting device 52 .

[0239] The alkali washing device 51 is connected to the oil recovery system 4 and the smoldering system 3 respectively.

[0240] The alkali cleaning device 51 is, for example, a storage tank containing alkali solution, and the acidic gas in the waste gas can be neutralized when the waste gas passes through the alkali cleaning device 51. Among them, when PVC is pyrolyzed, the main acidic gas generated is hydrogen chloride (HCl) and the like.

[0241] Under certain temperature and pressure conditions, some gases cannot condense and liquefy within the condensing device 42. The uncondensed gases pass through the alkaline washing device 51 to remove the acidic gases. The remaining uncondensed gases can be used as supplemental fuel for heating in the pyrolysis rotary kiln 2, thereby saving energy. Common non-condensable gases include inert gases, methane, carbon monoxide, hydrogen, and other alkanes.

[0242] The demister 52 includes, for example, plates, a supporting device, etc. During the spray absorption process, the demister 52 captures the mist particles and slurry droplets entrained in the exhaust gas to purify the gas.

[0243] The adsorption unit 53 is, for example, activated carbon, which adsorbs carbon monoxide, carbon dioxide, etc., filters out tiny particles in the gas, and achieves gas purification.

[0244] When the exhaust gas treatment system 5 is connected to the smoldering system 3, it also needs to be subjected to alkaline washing treatment to remove the acidic gas therein, and then processed through the demisting device 52 and the adsorption unit 53 so that the gas meets the emission standards.

[0245] It should be noted that the waste wind blade processing devices described in this application are all controlled by a control system, which can be a pre-stored program. Each system or unit can have a separate control system, which is then controlled by a central control terminal, or a shared control system can be used to control the waste wind blade processing devices. The specific implementation will depend on the actual situation.

[0246] In the related art, the waste fan blades are decomposed by calcination, and microscopic characterization and observation are carried out using a SU3500 tungsten filament scanning electron microscope (SEM). In this decomposition method, it can be observed that when the material is thermally decomposed, molten balls will appear, or the polymer partially connected to the fiber will have an obvious molten smooth surface. The higher the temperature, the more serious the performance of the glass fiber will be damaged and the glass fiber cannot be used in a high-value manner. The material after pyrolysis itself has a certain temperature and has a large amount of pyrolytic carbon attached, which results in a waste of energy. It does not utilize the characteristics of the glass fiber itself after pyrolysis, and does not achieve full utilization of resources.

[0247] The waste fan blade processing device in this application can realize resource recycling of waste fan blades. The waste fan blade processing device is a complete set of equipment with a high organic matter disposal rate, clean products, and a safe and efficient process.

[0248] The pyrolysis of discarded fan blades generates small organic molecules. This simple and efficient process, without the need for high pressure or the addition of specialized media, allows for rapid disposal of discarded fan blades. Pyrolysis can address the issue of strong fiber / resin interfacial bonding and difficulty in separation, converting discarded fan blades into gaseous small molecules.

[0249] During the processing of discarded wind turbine blades, the treatment device is mainly based on phase separation of the composite system to extract high-temperature resistant components such as glass fiber, which effectively solves the problem of strong interfacial bonding and difficult separation of fibers and resins in fiber-reinforced composite materials in discarded wind turbine blades, realizes large-scale and continuous disposal, and improves processing efficiency.

[0250] Using vehicle-mounted mobile automatic fan blade cutting equipment, the cutting water jet speed and knife position are adjusted according to program control for discarded fan blades of different thicknesses, saving cutting time and improving equipment processing efficiency.

[0251] The smoldering system utilizes the material's own temperature and the porous properties of the glass fiber to self-sustain combustion in an oxidant environment, removing carbon deposits on the glass fiber surface and restoring its original color. This effectively avoids significant degradation of the glass fiber's performance, eliminates the need for an external heat source, and relies on self-sustaining combustion to save energy.

[0252] The waste gas treatment system ensures that the generated waste gas meets emission standards, avoiding environmental pollution. Under certain temperature and pressure conditions, some gases cannot be condensed and liquefied in the condensation equipment. The uncondensed gas passes through the alkaline washing device to remove the acidic gases. The remaining uncondensed gas is used as supplementary material for heating the pyrolysis rotary kiln, achieving resource recycling, energy conservation, and low-energy operation.
