Description

Technical Field

[0001] This disclosure relates to the technical field of wind power equipment manufacturing, and in particular to a wind power fiber cloth cutting device. Background Technology

[0002] In related technologies, the tail end of the fiber cloth layer is cut off as a whole and chamfered using a guillotine.

[0003] However, in this method, the guillotine needs to span the entire fabric width and cut it off in one go. In other words, the length of the guillotine needs to be matched with the width of the fiber fabric layer. It can only be used for fiber fabrics of equal width. It is completely unsuitable for locations where the width varies. Summary of the Invention

[0004] The purpose of this disclosure is to provide a wind power fiber cloth cutting device that can be used to cut fiber cloth layers of different widths.

[0005] According to one aspect of this disclosure, a wind power fiber cloth cutting device is provided, the wind power fiber cloth cutting device comprising: a worktable for supporting a fiber cloth layer; a cutting assembly having a driving component and a cutting element, the driving component driving the cutting element to move intermittently along a direction perpendicular to the worktable, so that the cutting element cooperates with the worktable to intermittently cut the fiber cloth layer; and a conveying assembly driving the fiber cloth layer to move intermittently along a first direction on the worktable, wherein the intermittent movement of the fiber cloth layer along the first direction is alternated with the intermittent cutting of the fiber cloth layer by the cutting element, the single movement distance of the fiber cloth layer driven by the conveying assembly along the first direction is greater than the cutting length formed by the cutting element on the fiber cloth layer along the first direction; when the driving component drives the cutting element to move intermittently along a direction perpendicular to the worktable, and the conveying assembly drives the fiber cloth layer to move intermittently along the first direction on the worktable, the cutting element cuts a plurality of notches spaced apart along the first direction on the fiber cloth layer.

[0006] The technical solution provided in this disclosure includes a cutting device comprising a conveying component and a cutting component. The conveying component intermittently conveys the fiber cloth layer along a first direction, and the single movement distance of the fiber cloth layer along the first direction driven by the conveying component is greater than the cutting length formed by the cutting component along the first direction on the fiber cloth layer. This causes the fiber cloth layer to intermittently change the area below the cutting component, and in conjunction with the intermittent downward cutting of the cutting component, the cutting component can gradually cut the fiber cloth layer to form several spaced notches until the cutting is complete. This satisfies the chamfering requirement at the end of the fiber cloth layer. Compared to a guillotine-type cutting method, the wind power fiber cloth layer cutting device of this disclosure can be used to cut fiber cloth layers of different widths. When the width of the fiber cloth layer changes, it is not necessary to purchase a complete set of cutting tools again; only adjustments or replacements of some components are needed to meet the requirements. This fundamentally avoids repeated equipment purchases, significantly reducing initial investment and greatly reducing repeated equipment purchase costs. Furthermore, the corresponding cutting components can be made relatively small to facilitate replacement operations and reduce labor intensity.

[0007] Optionally, the cutting component includes a connecting seat and two cutting blades; the connecting seat is detachably connected to the driving component; the two cutting blades are disposed on the connecting seat, and the two cutting blades intersect with the extension direction of the fiber bundles of the fiber cloth layer.

[0008] The above solution allows for a detachable connection between the connecting seat and the drive component, facilitating the removal and replacement of the cutting parts to meet different cutting needs and simplifying maintenance. Two cutting blades are mounted on the connecting seat, intersecting the extension direction of the fiber bundles in the fiber cloth layer. This allows the cutting blades to sever the fiber bundles, separating the severed fiber bundles from the overall structure.

[0009] Optionally, the two cutting blades are joined end to end and configured in a V-shape.

[0010] With the above scheme, the two sides of the notch are beveled, so that the fiber bundles on both sides can bend into the notch to fill it, so that the end of the fiber cloth layer gradually thins out, which is convenient for forming a chamfer.

[0011] Optionally, the two cutting blades are arranged parallel and staggered.

[0012] With the above scheme, the two sides of the notch are stepped, so that the fiber bundles on both sides can bend into the notch to fill it, so that the end of the fiber cloth layer gradually thins out, which is convenient for forming a chamfer.

[0013] Optionally, the connecting seat is connected to the conveying component via a linkage component; when the driving component drives the connecting seat to move away from the worktable, the connecting seat drives the conveying component to drive the fiber cloth layer to move along the first direction via the linkage component.

[0014] With the above solution, the conveying component and the cutting component share the same driving component. Driven by the driving component, the conveying component realizes material conveying, and the cutting component simultaneously completes material cutting, thereby simplifying the overall structure and reducing manufacturing costs.

[0015] Optionally, the conveying assembly includes a pusher plate and a pressure plate; the pressure plate is connected to the worktable, and the fiber cloth layer is confined between the pressure plate and the worktable; the worktable is provided with a clearance hole, the pusher plate is located in the clearance hole, and the pusher plate is connected to the linkage assembly; wherein, when the driving component drives the connecting seat to move away from the worktable, the connecting seat drives the pusher plate to extend from the table surface of the worktable and move in the first direction through the linkage assembly; when the driving component drives the connecting seat to move towards the worktable, the connecting seat drives the pusher plate to retract below the table surface of the worktable and move in the opposite direction to the first direction through the linkage assembly.

[0016] Through the above scheme, the pressure plate can apply downward pressure to the fiber cloth layer, increase the friction between the fiber cloth layer and the pusher plate, so that the pusher plate can drive the fiber cloth layer to move.

[0017] Optionally, the linkage assembly includes a connecting rod, an eccentric shaft, a moving block, and a limiting rod; one end of the connecting rod is rotatably connected to the connecting seat, and the other end of the connecting rod is rotatably connected to the first end of the eccentric shaft; the eccentric shaft includes a first end, a second end, and an intermediate shaft portion; the axes of the first end and the second end are not collinear with the axis of the intermediate shaft portion; the intermediate shaft portion is rotatably connected to the worktable; the second end is rotatably connected to the moving block; the top surface of the moving block is detachably connected to the pusher plate; the bottom surface of the moving block is provided with a limiting hole; one end of the limiting rod is inserted into the limiting hole; and the limiting rod is slidably connected to the worktable in a direction parallel to the first direction.

[0018] The above solution results in a simple linkage structure, a small footprint, and reduced production costs.

[0019] Optionally, the wind power fiber cloth cutting device further includes a suction component, which is located in front of the worktable along the first direction, and the suction port of the suction component is correspondingly arranged with respect to the cutting area of ​​the fiber cloth.

[0020] The above solution utilizes a suction component to remove debris and dust generated during the cutting process in real time, avoiding the problems of dust and debris accumulation in traditional cutting operations. This protects the health of employees, reduces subsequent cleaning work, and improves overall operational efficiency. Furthermore, it is worth noting that the cut area on the fiber cloth layer can be moved to the suction component. The suction component not only removes dust but also applies force to the fiber bundle, causing it to bend into the notches on both sides to form a chamfer, eliminating the need for an additional fiber bending step.

[0021] Optionally, the wind power fiber cloth cutting device further includes an energy source, a safety switch, and a control switch; the energy source is electrically connected to the drive component, and the safety switch and the control switch are connected in series in the circuit connecting the energy source and the drive component.

[0022] With the above solution, the drive component can only be started by pressing the safety switch and the control switch at the same time, thereby preventing accidental start-up when not in use and improving safety.

[0023] Optionally, the wind power fiber cloth cutting device further includes a base, and the workbench, the cutting assembly, the conveying assembly, the energy source, the safety switch and the control switch are connected to the base; the energy source is detachably connected to the base, and / or, the base is provided with two grip handles.

[0024] The above solution allows the wind power fiber cloth cutting device to be connected as a single unit, facilitating easy transport and installation. The base is equipped with two handles, allowing for two-handed gripping of the tool. The handles are of suitable thickness to prevent fatigue during single-handed operation, making it convenient and practical. Attached Figure Description

[0028] In the manual or automated layup process of composite laminates, multiple fiber cloth layers are typically laid one on top of the other. Due to the different ending positions of some fiber cloth layers and the certain thickness of the fiber cloth layers, stepped gaps exist between adjacent fiber cloth layers. These stepped gaps may lead to resin accumulation or cavitation during subsequent resin injection, thus affecting the overall structural strength of the wind turbine blades. Therefore, it is usually necessary to chamfer the ends of the pre-terminated fiber cloth layers to ensure a smooth transition between fiber cloth layers and reduce the generation of stepped gaps.

[0029] In related technologies, such as Figure 1As shown, the tail of the fiber cloth layer is cut as a whole by a guillotine, thereby forming several spaced fiber sheets 11 and gaps 12 between two adjacent fiber sheets. Then, the fiber bundles on the fiber sheets can be mixed in random directions. During the mixing process, the fiber bundles can bend into the gaps 12 on both sides and a smaller number of fiber bundles will extend to the same position, so that the thickness of the fiber sheet gradually becomes thinner and fills the gaps 12, forming a chamfer treatment.

[0030] However, this method requires the guillotine to span the entire fabric width, vertically cutting a single layer of monoaxial fabric in one go. While the guillotine process is simple and fast, it needs to be adapted to the fabric width. If the width of the fabric changes even slightly, the entire guillotine, along with its holder and guide rails, must be removed and replaced with a new guillotine of the corresponding specifications. Preparing, changing, and adjusting guillotines not only slows down production but also significantly increases inventory costs and downtime. Furthermore, the weight of the guillotine increases almost linearly with the fabric width, making it quite heavy. During operation, operators repeatedly lift, place, and align the guillotine on the die surface, resulting in high labor intensity. In addition, the inherent structure of the integral guillotine cutting method means it can only be used for fabrics of uniform width; it is completely unsuitable for locations with varying widths.

[0031] To address this issue, this disclosure presents a cutting device comprising a conveying component and a cutting component. The conveying component intermittently conveys a fiber cloth layer along a first direction. The fiber cloth layer can intermittently change the area located below the cutting component, coordinating with the intermittent downward cutting of the cutting component. This allows the cutting component to gradually cut the fiber cloth layer until the cutting is complete. In this way, compared to a guillotine-type cutting method, the wind power fiber cloth cutting device of this disclosure can be used to cut fiber cloth layers of different widths. When the width of the fiber cloth layer changes, there is no need to purchase a complete set of cutting tools again; only adjustments or replacements of some components are needed to meet the requirements. This fundamentally avoids redundant equipment purchases, significantly reducing initial investment and substantial reduction in equipment repurchase costs. Furthermore, the corresponding cutting components can be made relatively small to facilitate component replacement and reduce labor intensity.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0033] This disclosure provides a wind power fiber cloth layer cutting device, which is mainly used to cut the tail of the fiber cloth layer 10 to facilitate the formation of a chamfer at the tail of the fiber cloth layer 10, so as to smoothly transition between two stacked fiber cloth layers 10 and reduce the generation of step gaps.

[0034] Specifically, such as Figures 1 to 4 As shown, the wind power fiber fabric cutting device includes a worktable 100, a cutting assembly 200, and a conveying assembly 300. The worktable 100 supports the fiber fabric 10, facilitating its flat laying and movement. The cutting assembly 200 has a driving component 210 and a cutting element 220. The driving component 210 drives the cutting element 220 to move intermittently in a direction perpendicular to the worktable 100, allowing the cutting element 220 to intermittently cut the fiber fabric 10 in conjunction with the worktable 100. In practical applications, the worktable 100 provides support for the bottom surface of the fiber fabric 10. As the cutting element 220 presses down, it and the worktable 100 cooperate to clamp and cut the fiber fabric 10. For example, the cutting element 220 can penetrate both the top and bottom surfaces of the fiber fabric 10, achieving a full cut. The cutting element 220 can also cut into a portion of the thickness of the fiber cloth layer 10 without penetrating to the bottom surface of the fiber cloth layer 10, thus partially cutting the fiber cloth layer 10.

[0035] The conveying assembly 300 is used to drive the fiber cloth layer 10 to move intermittently along a first direction on the worktable 100. The first direction is parallel to the surface of the worktable 100, and the intermittent movement of the fiber cloth layer 10 along the first direction is alternated with the intermittent cutting of the fiber cloth layer 10 by the cutting element 220. In other words, after the fiber cloth layer 10 moves along the first direction, the cutting element 220 cuts the fiber cloth layer 10, and after the cutting element 220 cuts the fiber cloth layer 10, the fiber cloth layer 10 moves along the first direction again, and so on. The single movement distance of the fiber cloth layer 10 driven by the conveying assembly 300 along the first direction is greater than the cutting length formed by the cutting element 220 on the fiber cloth layer 10 along the first direction. Thus, when the driving component 210 drives the cutting component 220 to move intermittently in a direction perpendicular to the worktable 100, and the conveying component 300 drives the fiber cloth layer 10 to move intermittently on the worktable 100 in the first direction, the cutting component 220 cuts a plurality of notches 12 spaced apart in the first direction on the fiber cloth layer 10, and fiber sheets 11 are formed between two adjacent notches 12. In this way, the conveying component 300 intermittently conveys the fiber cloth layer 10 in the first direction, and the fiber cloth layer 10 can intermittently change the area located below the cutting component 200, and cooperate with the intermittent downward cutting of the cutting component 200, so that the cutting component 200 can gradually cut the fiber cloth layer 10 until the cutting is completed. In this way, compared with the guillotine-type cutting method, the wind power fiber cloth cutting device disclosed herein can be used to cut fiber cloth layers 10 of different widths. When the width of the fiber cloth layer 10 changes, there is no need to purchase the entire set of cutting tools again; only adjustments or replacements of some components are needed to meet the requirements. This fundamentally avoids the repeated purchase of equipment, significantly reducing initial investment and greatly reducing the cost of repeated equipment purchases. Furthermore, the corresponding cutting component 220 can be made relatively small to facilitate the replacement of the cutting component 220 and reduce labor intensity.

[0036] In practical applications, the fiber cloth layer 10 can be conveyed along the first direction solely by the conveying component 300. Of course, manual or other traction equipment can also be used to provide auxiliary traction at its ends.

[0037] It should be noted that the fiber fabric layer 10 may have multiple stacked fiber layers, each fiber layer consisting of multiple fiber bundles, for example... Figure 1The dashed lines in the example represent fiber bundles in each fiber layer. When the cutter 220 makes a full cut to the fiber fabric layer 10, the notch 12 penetrates both the upper and lower surfaces of the fiber fabric layer 10. The notch 12 can be formed on each fiber layer. When the cutter 220 makes a partial cut to the fiber fabric layer 10, the notch 12 is a blind hole structure, and the notch 12 can be formed on a portion of the fiber layer. Regardless of whether the notch 12 is formed on each fiber layer or only on a portion of the fiber layer, the fiber bundles on the fiber sheet 11 can be mixed in random directions. During the mixing process, the fiber bundles can bend into the notches 12 on both sides, and fewer fiber bundles will extend to the same position, thereby making the thickness of the fiber sheet gradually thinner and filling the notches 12, forming a chamfered treatment.

[0038] In practical applications, the fiber cloth layer 10 can be fully or partially cut depending on its thickness. When a full cut is required, the driving component 210 can be controlled to lower the cutting element 220 so that it contacts the worktable 100. When a partial cut is required, the driving component 210 can be controlled to lower the cutting element 220 so that it remains at a distance from the worktable 100 after descent. Alternatively, switching between full and partial cuts can be achieved by using cutting elements 220 of different heights.

[0039] For example, the fiber layer 10 may include unidirectional fiber bundles, biaxial fiber bundles, triaxial fiber bundles, or multidirectional fiber bundles. For instance, the fiber bundles may be arranged longitudinally. For example, biaxial fiber bundles may be arranged at +45° / -45° or 0° / 90° relative to the main fiber direction. These fiber bundles may be made of glass, carbon, aramid, or organic materials such as hemp, flax, and jute. The fiber layer 10 may include a thermoplastic or thermosetting resin matrix. The fiber bundles may be pre-impregnated with the matrix as a "prepreg blank," or the matrix may be impregnated into the fiber layer during the manufacture of the composite structure, such as during layup or injection molding. Alternatively, the fiber layer 10 may be pre-impregnated with a resin foil on only one side, i.e., a "semi-prepreg."

[0040] Regarding the specific structure of the drive component 210, in some embodiments, the drive component 210 may adopt a linear movement structure such as a cylinder, hydraulic cylinder or electric cylinder to facilitate control of the cutting depth of the cutting component 220.

[0041] In some other embodiments, the drive component 210 may also adopt a motor and a rotary-linear conversion structure connected to the motor. The motor drives one end of the rotary-linear conversion mechanism to rotate, so that the other end of the rotary-linear conversion mechanism makes linear motion, thereby controlling the cutting part 220 to reciprocate and cut, simplifying the structure and reducing production costs.

[0042] In some embodiments, such as Figure 1 and Figure 4 As shown, the cutting component 220 may include a connecting seat 221 and two cutting blades 222. The connecting seat 221 is detachably connected to the drive component 210, thereby facilitating the disassembly and replacement of the cutting component 220 to meet different cutting needs and simplifying maintenance. The two cutting blades 222 are mounted on the connecting seat 221, and the two cutting blades 222 intersect the extending direction of the fiber bundles of the fiber cloth layer 10, so that the cutting blades 222 can cut the fiber bundles, causing the cut fiber bundle portion to separate from the whole portion.

[0043] Regarding the specific structure of the two cutting blades 222, this disclosure provides two possible embodiments for reference.

[0044] Example 1, such as Figure 1 and Figure 4 As shown, the two cutting blades 222 are connected end to end and constructed in a V-shape. When the fiber cloth layer 10 is cut using these two cutting blades 222, the resulting notch 12 is triangular in shape. Thus, the two sides of the notch 12 are beveled, which allows the fiber bundles on both sides to partially bend into the notch 12 and fill it. This makes the end of the fiber cloth layer 10 gradually thinner, which is convenient for forming a chamfer.

[0045] Example 2, as follows Figure 5 and Figure 6 As shown, the two cutting blades 222 are parallel and staggered. When the fiber cloth layer 10 is cut by these two cutting blades 222, the cut notch 12 is stepped, so that the two sides of the notch 12 are stepped surfaces, so that the fiber bundles on both sides can bend into the notch 12 to fill the notch 12, so that the end of the fiber cloth layer 10 gradually thins out, which is convenient for forming a chamfer.

[0046] In some embodiments, such as Figure 7 and Figure 8 As shown, the connecting seat 221 is connected to the conveying assembly 300 via a linkage component. When the driving component 210 moves the connecting seat 221 away from the worktable 100, the connecting seat 221 drives the conveying assembly 300 to move the fiber cloth layer 10 along the first direction via the linkage component. That is, the conveying assembly 300 and the cutting assembly 200 share the same driving component 210. Under the drive of the driving component 210, the conveying assembly 300 realizes material conveying, and the cutting assembly 200 simultaneously completes material cutting, thereby simplifying the overall machine structure and reducing manufacturing costs.

[0047] Specifically, the conveying assembly 300 may include a pusher plate 310 and a pressure plate 320. The pressure plate 320 is connected to the worktable 100, and the fiber cloth layer 10 is confined between the pressure plate 320 and the worktable 100, so that the pressure plate 320 can apply downward pressure to the fiber cloth layer 10, increasing the friction between the fiber cloth layer 10 and the pusher plate 310, so that the pusher plate 310 can drive the fiber cloth layer 10 to move. The worktable 100 is provided with a clearance hole 110. The orthographic projection of the cutting piece 220 on the worktable 100 is located outside the clearance hole 110. The pusher plate 310 is located inside the clearance hole 110 and is connected to the linkage assembly. When the driving component 210 drives the connecting seat 221 to move away from the worktable 100, the connecting seat 221 drives the pusher plate 310 to extend from the table surface of the worktable 100 and move in the first direction through the linkage assembly. When the driving component 210 drives the connecting seat 221 to move towards the worktable 100, the connecting seat 221 drives the pusher plate 310 to retract below the table surface of the worktable 100 and move in the opposite direction to the first direction through the linkage assembly.

[0048] In practical applications, the top surface of the pusher plate 310, which is the side of the pusher plate 310 that contacts the fiber cloth layer 10, is provided with several spaced protrusions, such as teeth or bumps, to insert into the small grooves on the surface of the fiber cloth layer 10, or to increase the friction with the fiber cloth layer 10, so as to facilitate the movement of the fiber cloth layer 10. The pressure plate 320 can apply pressure to the fiber cloth layer 10 by utilizing its own elastic properties. A torsion spring can also be provided between the pressure plate 320 and the worktable 100, and the torsion spring drives the pressure plate 320 to apply pressure to the fiber cloth layer 10.

[0049] In some embodiments, such as Figure 7 and Figure 8 As shown, the linkage assembly may include a connecting rod 410, an eccentric shaft 420, a moving block 430, and a limiting rod 440. One end of the connecting rod 410 is rotatably connected to the connecting seat 221, and the other end of the connecting rod 410 is rotatably connected to the first end 421 of the eccentric shaft 420. The eccentric shaft 420 includes a first end 421, a second end 422, and an intermediate shaft portion 423. The axes of the first end 421 and the second end 422 are not collinear with the axis of the intermediate shaft portion 423. The intermediate shaft portion 423 is rotatably connected to the worktable 100, and the second end 422 is rotatably connected to the moving block 430. The top surface of the moving block 430 is detachably connected to the pusher plate 310 to facilitate the maintenance and replacement of the pusher plate 310. The bottom surface of the moving block 430 is provided with a limiting hole 431, and one end of the limiting rod 440 is inserted into the limiting hole 431. The limiting rod 440 is slidably connected to the worktable 100 in a direction parallel to the first direction, so that the pusher plate 310 always maintains a state of parallel movement with the table surface of the worktable 100. In this way, the linkage structure is simple, occupies little space, and reduces production costs.

[0050] During the cutting process, with Figure 7 Taking the shown perspective as an example, when the driving component 210 drives the cutting assembly 200 to move downward, the cutting assembly 200 cuts the limiting fabric layer 10. At the same time, the connecting seat 221 drives the connecting rod 410 to move downward. The connecting rod 410 pushes the first end 421 to rotate in an arc shape to the lower left, and the second end 422 follows suit to rotate in an arc shape to the lower left, thereby driving the moving block 430 and the pusher plate 310 on it to move to the lower left. When the driving component 210 drives the cutting assembly 200 to move upward, the cutting assembly 200 resets. At the same time, the connecting seat 221 drives the connecting rod 410 to move upward. The connecting rod 410 pushes the first end 421 to rotate in an arc shape to the upper right, and the second end 422 follows suit to rotate in an arc shape to the upper right, thereby driving the moving block 430 and the pusher plate 310 on it to move to the upper right, thereby extending the clearance hole 110 to contact the fiber fabric layer 10 and driving the fiber fabric layer 10 to move along the first direction.

[0051] In practical applications, one end of the connecting rod 410 can be directly rotatably connected to the connecting seat 221, or it can be indirectly rotatably connected to the connecting seat 221 through a transmission rod. A slide rod extending along the first direction can be provided below the worktable 100, and the limiting rod 440 is slidably connected to the slide rod, thereby realizing the sliding connection between the limiting rod 440 and the worktable 100 in a direction parallel to the first direction.

[0052] In some embodiments, such as Figure 2 and Figure 3 As shown, the wind power fiber cloth cutting device may also include a suction component 500, which is located in front of the workbench 100 along the first direction, and the suction port of the suction component 500 is correspondingly set to the cutting area of ​​the fiber cloth 10. In this way, the suction component 500 can pick up the debris and dust generated during the cutting process in real time, avoiding the problems of dust flying and debris accumulation in traditional cutting operations. This not only protects the health of employees but also reduces subsequent cleaning work and improves overall work efficiency. Furthermore, it should be noted that the area cut on the fiber cloth 10 can be moved to the suction component 500. The suction component 500 not only serves to suck up dust but also applies force to the fiber bundle, causing the fiber bundle to bend under suction and form a chamfer in the notches 12 on both sides, without the need for an additional fiber bundle bending step.

[0053] In practical applications, the suction component 500 can be provided with suction by a negative pressure device, such as a negative pressure fan.

[0054] In some embodiments, the wind power fiber fabric cutting device further includes an energy source 600, a safety switch 610, and a control switch 620. The energy source 600 is electrically connected to the drive component 210, and the safety switch 610 and control switch 620 are connected in series in the circuit connecting the energy source 600 and the drive component 210. Thus, the drive component 210 can only be activated by simultaneously pressing the safety switch 610 and the control switch 620, thereby preventing accidental activation when not in use and improving operational safety.

[0055] In practical applications, the energy source 600 can be a battery or a plug connected to an external power source. The safety switch 610 and the control switch 620 should be located in different positions, such as on different surfaces, to avoid the possibility of accidental activation causing both switches to be pressed simultaneously.

[0056] Furthermore, the wind power fiber fabric cutting device also includes a base 700, a worktable 100, a cutting assembly 200, a conveying assembly 300, an energy source 600, a safety switch 610, and a control switch 620 connected to the base 700. This allows the wind power fiber fabric cutting device to be connected as a single unit, facilitating integrated handling and installation.

[0057] Furthermore, the energy source 600 is detachably connected to the base 700 for easy and timely replacement.
