Description

Technical Field

[0001] The utility model relates to the field of wind power blade processing, in particular to a double cutter for a pultruded plate of a wind power blade. Background Art

[0002] As the "vertebra" of a wind power blade, the girder is the most important component of the wind power blade, responsible for mainly bearing and providing the stiffness of the blade. The quality of the girder directly affects the strength and service life of the blade. With the development of wind power blades towards large sizes, more than 90% of the blade girders are prepared by pultruded plates. The manufacturing process of the girder is as follows: After the operator puts the coiled pultruded plate into the unwinding device, closes the safety door, and starts the machine, the coiled plate is transmitted to the cutting and grinding room through high-strength pulling; after the grinding process is completed, the pultruded plate is pushed to the conveyor belt area, cut according to the required length, and then an adsorption tool is used to lift the cut pultruded plate and place it side by side on the laid fiberglass cloth according to the specified quantity requirements; then the cloth laying and placing of the pultruded plate are repeated. After multiple layings and stackings, a blade girder is completed. After the prefabricated girder is positioned according to the size requirements, the main girder is placed inside the blade, and then it is poured and demolded together with the fiberglass cloth and the core material. After a series of processes, the girder officially becomes a structural component of the wind power blade.

[0003] However, when cutting the pultruded plate, the existing cutting method is to place the cutting tool above the pultruded plate for horizontal cutting. This cutting method has a slow cutting speed, and generally, the existing cutting method can only achieve the cutting of one station, that is, only one cutting tool is set on one cutting machine, resulting in low cutting efficiency.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] The present utility model provides a double cutter for the pultruded plate of the wind turbine blade, as Figures 1-7As shown in the figure, it includes a frame 1 which is fixed on the ground. Above the frame 1, there is a workbench 2. On the workbench 2, two cutting grooves 3 which are symmetrically arranged on the same straight line are provided. The two cutting grooves 3 are located in the length direction of the workbench 2 and are symmetrically arranged. Inside the frame 1, cutting components are symmetrically provided, that is, the cutting components are located below the workbench 2. The cutting components include cutting blades 4. The cutting blades 4 correspond to the cutting grooves 3 one by one. The cutting blades 4 are connected to a control device. The control device can make the cutting blades 4 rotate and can extend through the corresponding cutting grooves 3 out of the workbench 2.

[0031] In the specific application process, the width range of the pultruded plate of the wind turbine blade cut by the double cutter is 75 mm to 200 mm. Place the pultruded plate to be cut on the workbench 2. Since there are two cutting grooves 3, two sections of the pultruded plate to be cut can be placed at the cutting grooves 3. The cutting blades 4 are located below the workbench 2. By controlling the control device, make the cutting blades 4 rotate and make the cutting blades 4 pass through the cutting grooves 3 and rise towards the workbench 2. The rotating cutting blades 4 will cut the pultruded plate on the workbench 2. Moreover, the cutting blades 4 are circularly arranged and are located below the pultruded plate. Therefore, the cutting direction of the cutting blades 4 for the pultruded plate is vertical cutting, and it can cut from the middle of the pultruded plate to both sides. So the cutting speed is greatly improved. Furthermore, by setting two cutting grooves 3, two sections of the pultruded plate can be cut simultaneously each time, greatly improving the cutting efficiency.

[0032] In this embodiment, the direction where the cutting grooves 3 are located is parallel to the length direction of the workbench 2. The length of the cutting grooves 3 is greater than the diameter of the cutting blades 4 so that the cutting blades 4 can smoothly pass through the cutting grooves 3. A dust suction hood 5 is provided above the cutting grooves 3. The dust suction hood 5 can cover the cutting grooves 3. Brushes 6 are provided on the two side walls of the dust suction hood 5. When cutting the pultruded plate, a large amount of flying dust and droplets will be generated. By setting the dust suction hood 5, the outward diffusion of the flying dust and droplets is effectively prevented from affecting the air environment. By setting the brushes 6, the gaps of the cutting grooves 3 are completely sealed, further preventing the spread of the flying dust and droplets, and achieving the effect of further protecting the environment.

[0033] In this embodiment, the cutting assembly further includes a cutting shaft 7. The cutting shaft 7 is fixedly connected to the cutting blade 4. A pulley 8 is sleeved outside the cutting shaft 7. The outside of the pulley 8 is connected to a belt 9, and the belt 9 is connected to the output shaft of the motor 10. A cutting cover 11 is provided on the outer periphery of the cutting blade 4. The cutting cover 11 is fixedly connected to the frame 1. Guide grooves 12 are provided on both side walls of the cutting cover 11. The cutting shaft 7 passes through the guide grooves 12 and the cutting shaft 7 can slide up and down along the guide grooves 12. The motor 10 is fixedly connected to a motor bracket 13. Symmetrically fixed to the outside of the vertical side wall of the motor bracket 13 are sliders 14. Inside the frame 1 is fixedly connected a slide rail bracket 15. Symmetrically provided on the outside of the vertical side wall of the slide rail bracket 15 are slide rails 16. The sliders 14 are matched with the slide rails 16. Fixedly connected to the slide rail bracket 15 is a lifting cylinder 17. The movable end of the lifting cylinder 17 is connected to the slider 14. The lifting cylinder 17 can drive the slider 14 to slide on the corresponding slide rail 16. The motor 10 and the lifting cylinder 17 are connected to a control device.

[0034] Specifically, when cutting the pultruded plate, by controlling the control device, the motor 10 is started to work. The output shaft of the motor 10 rotates. The rotation of the output shaft drives the rotation of the belt 9. The rotation of the belt 9 drives the rotation of the pulley 8. The rotation of the pulley 8 drives the rotation of the cutting shaft 7. The rotation of the cutting shaft 7 drives the rotation of the cutting blade 4. In addition, the cutting assembly is fixedly connected to the frame 1 through the slide rail bracket 15. During cutting, by controlling the control device, the lifting cylinder 17 is started. The movement of the movable end of the lifting cylinder 17 drives the slider 14 to slide upward along the corresponding slide rail 16. The upward sliding of the slider 14 drives the motor bracket 13 to slide upward accordingly, and further drives the cutting assembly to slide upward, that is, drives the cutting blade 4 to slide upward along the guide groove 12. The cutting blade 4 slides upward through the corresponding cutting groove 3 to the lower side of the pultruded plate. With its own rotation, the cutting of the pultruded plate is realized. The cutting assembly is arranged below the pultruded plate, that is, the pultruded plate is cut in the vertical direction, and can be cut from the middle of the pultruded plate to both sides, improving the cutting speed.

[0035] In this embodiment, the positions of the two cutting grooves 3 correspond to the first station 18 and the second station 19 respectively. By setting two stations, when cutting the pultruded plate each time, the two sections of the pultruded plate to be cut can be cut simultaneously, realizing double cutting at double stations and improving the cutting efficiency. Horizontal guiding components are symmetrically arranged at the inlet end and the outlet end of the workbench 2. The horizontal guiding component includes an arc-shaped guiding plate 20 and a horizontal positioning cylinder 21. The arc-shaped guiding plate 20 and the horizontal positioning cylinder 21 are sequentially arranged on the side of the first station 18 away from the second station 19. The arc-shaped guiding plate 20 is vertically arranged, and the movable end of the horizontal positioning cylinder 21 can horizontally move onto the first station 18. A guiding wheel 22 is arranged on the side of the first station 18 close to the second station 19, and the guiding wheel 22 can rotate around its own axis. Along the length direction of the workbench 2, the second station 19 is symmetrically provided with the same horizontal positioning cylinder 21, arc-shaped guiding plate 20 and guiding wheel 22 as those of the first station 18. A protection plate 23 is arranged on the outer side of the two guiding wheels 22 away from the workbench 2, and the protection plate 23 is vertically arranged. The horizontal orientation cylinder is connected to the control device. By setting the protection plate 23, it not only plays a role in protecting the guiding wheel 22, but also plays a role in guiding the pultruded plate.

[0036] Specifically, when the pultruded plate is to be cut or has been cut, the conveyor belt may cause the direction of the pultruded plate to deviate. This device is provided with horizontal guiding components at both stations. When the pultruded plate is to be cut or has been cut, first, the arc-shaped guiding plate 20 will guide the pultruded plate to remain on the conveying path, and then through the control device, the horizontal positioning cylinder 21 is started, so that the movable end of the horizontal positioning cylinder 21 abuts against the pultruded plate in the direction close to the pultruded plate, making one side of the pultruded plate abut against the horizontal positioning cylinder 21, and the other end of the pultruded plate will abut against the side wall of the guiding wheel 22. The rotation of the guiding wheel 22 also increases the guiding effect on the pultruded plate, ensuring the cutting accuracy.

[0037] In this embodiment, along the width direction of the workbench 2, vertical pressing components are respectively arranged on both sides of the two cutting grooves 3. The vertical pressing component includes a pressing bracket 24, and the pressing bracket 24 is fixedly connected to the frame 1. The pressing bracket 24 is fixedly connected with two pressing cylinders 25. The two pressing cylinders 25 are symmetrically arranged and the positions of the two pressing cylinders 25 respectively correspond to the two cutting grooves 3. The movable ends of the pressing cylinders 25 can vertically move onto the workbench 2, and the pressing cylinders 25 are connected to the control device.

[0038] Specifically, the pultruded board is placed in a roll. Therefore, when cutting the pultruded board, it is easy to curl at the edges. This device is provided with a vertical pressing component to achieve pressing the pultruded board in the vertical direction during cutting to ensure the cutting accuracy. During cutting, through the control device, the pressing cylinders 25 before and after the cutting groove 3 are started. The movable ends of the pressing cylinders 25 will abut against the pultruded board, that is, apply pressure to the pultruded board in the vertical direction to achieve pressing the front and rear ends of the cutting position of the pultruded board and ensure the cutting accuracy.

[0039] In this embodiment, a fitting rod 26 is provided on the side of the vertical pressing component away from the pressing bracket 24. The lower part of the fitting rod 26 is inclined, and the inclination direction is from the outside of the vertical pressing component to the inside of the vertical pressing component. Since the pultruded board is placed in a roll, the pultruded board to be cut will warp. The fitting rod 26 can make the warped pultruded board fit the workbench 2 better to facilitate cutting. A guide roller 27 is provided on the side of the fitting rod 26 close to the pressing cylinder 25. By providing the guide roller 27, when cutting, the pultruded board enters below the guide roller 27 to enter the conveying path, which plays a guiding role for the pultruded board.

[0040] In this embodiment, a wiring box 28 is provided above the vertical pressing component. The wiring box 28 is fixedly connected to the frame 1 through a wiring box bracket 29, which not only effectively protects the plugs and connecting wires, but also makes the device space cleaner and reduces the possibility of tripping.

[0041] The present utility model uses specific examples to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
