Description

Technical Field

[0001] This utility model relates to the field of wind turbines, and in particular to a roller machine for producing wind turbine impellers. Background Technology

[0002] A cross-flow fan is a type of fan. Referring to the compressed cross-flow fan disclosed in patent number 201810779638.8, the main part of this cross-flow fan is the fan wheel body, which includes several blades and rings arranged at intervals on the blades for fixing the blades. The ring has many positioning holes. In the existing technology, when producing the wind turbine wheel body, all blades are first inserted into the positioning holes of all the rings to form a preliminary installation. Then, it is placed on a rolling mill. The rolling mill has pins at both ends to position the unfinished wind turbine wheel body, thereby preventing the unfinished wind turbine wheel body from detaching. The rolling mill has two sets of rollers, each set of rollers is equipped with several pressure rollers, and the pressure rollers correspond to the positions of the rings. Both sets of rollers are connected to the feeding mechanism, which is a lead screw and wheel structure. The operator needs to manually control the roller feeding distance. During processing, the motor drives the rollers to rotate, and then the operator controls the feeding amount of the rollers through the feeding mechanism, so that the pressure rollers on the two sets of rollers abut against the edge of the ring on the unfinished wind turbine wheel body. As the feeding amount increases, the pressure rollers continuously squeeze the edge of the ring, thereby forcing the ring to deform inward and thus clamping the blades. However, this method has a drawback: if the deformation of the wheel ring is too large, the produced wind turbine wheel body will be a defective product. Therefore, this processing method requires high skill levels from the operators, which means that companies need to spend a certain amount of money on employee training. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a more convenient roller machine for producing wind turbine wheels.

[0004] The technical solution adopted by this utility model to solve the problem is: a roller machine for producing wind turbine impellers, comprising:

[0005] The frame has two sets of rollers installed along the front-to-back direction. Each set of rollers is equipped with several active pressure rollers. The unshaped fan wheel can be placed on the two sets of rollers and supported by the active pressure rollers.

[0006] A drive motor is arranged at the bottom of the frame and is connected to two sets of rollers to drive the two sets of rollers to rotate in the same direction.

[0007] A movable frame is arranged on the machine frame. An auxiliary shaft is provided on the movable frame. Several freely rotatable driven pressure rollers are pivotally connected to the auxiliary shaft. A drive cylinder for driving the movable frame to move is arranged on the machine frame.

[0008] A fixed side frame is provided, which is arranged on one side above the roller, and a movable side frame is provided on the other side above the roller. A feed drive is connected to the movable side frame.

[0009] When the unshaped wind turbine wheel is placed on two sets of rollers, the wheel ring of the unshaped wind turbine wheel is supported by the active pressure roller. The drive cylinder can drive the movable frame to move, thereby moving the driven pressure roller to abut against the surface of the wheel ring of the unshaped wind turbine wheel. The central angle formed by the three contact points formed when the two sets of active pressure rollers and the driven pressure roller abut against the wheel ring is greater than 180 degrees.

[0010] As a further improvement to the above technical solution, the movable frame is pivotally connected to the top of the machine frame in the middle, the auxiliary shaft is arranged at the front end of the movable frame, a drive mating plate is provided at the rear end of the movable frame, the drive cylinder is arranged on the rear side of the machine frame, and the output end of the drive cylinder is located below the drive mating plate and can abut against the bottom surface of the drive mating plate.

[0011] As a further improvement to the above technical solution, an extension handle is also provided at the front end of the movable frame.

[0012] As a further improvement to the above technical solution, the movable frame includes a left frame plate and a right frame plate, the two ends of the auxiliary shaft are respectively connected to the front ends of the left frame plate and the right frame plate, and the drive mating plate is respectively connected to the top of the rear ends of the left frame plate and the right frame plate;

[0013] A balance plate is installed at the top front end of the left and right frame plates, and the extension handle is arranged on the surface of the balance plate.

[0014] As a further improvement to the above technical solution, a return torsion spring is provided between the movable frame and the machine frame.

[0015] As a further improvement to the above technical solution, both the active and driven pressure rollers are provided with annular grooves, and the wheel rings on the unshaped fan wheel body are inserted into the annular grooves.

[0016] As a further improvement to the above technical solution, a support frame is provided on the top of the frame, the drive cylinder is arranged on the top of the support frame with the output end of the drive cylinder facing the surface of the frame, the movable frame is arranged on the support frame and located below the drive cylinder, and the movable frame is fixedly connected to the output end of the drive cylinder.

[0017] As a further improvement to the above technical solution, a first gear is provided at the end of each of the two rollers, and the two first gears mesh with each other through a second gear. A first sprocket is also arranged at the end of one of the rollers, and the drive motor is connected to the first sprocket through a chain.

[0018] The beneficial effects of this utility model are as follows: During production, the pre-assembled and unshaped fan wheel body is placed on two sets of rollers, and the feed drive is activated. This causes the moving fixed side frame to press all the blades towards the fixed side frame, ensuring the neatness of all blades. Simultaneously, the position of the wheel ring is manually adjusted so that it is positioned precisely on the surface of the driving pressure roller. The drive cylinder and drive motor are then activated. The drive cylinder moves the movable frame, causing the driven pressure roller to press against the surface of the wheel ring. The drive motor drives the rollers and the driving pressure roller to rotate, thereby rotating the fan wheel body. This ensures that the edge of the wheel ring rotates at a uniform speed without interruption. The impeller engages with both the active and driven pressure rollers. The drive cylinder gradually increases the applied force and feed, causing the driven pressure roller to continuously squeeze the edge of the ring, deforming the edge and completing the assembly. During this process, when the force applied by the drive cylinder exceeds the specified value, it indicates that the squeezing of the ring has been completed. At this point, the drive cylinder resets and the drive motor stops, making it easy to remove the completed wind turbine wheel. In this way, the production process is standardized, and the force used to squeeze and deform the ring is controlled by the drive cylinder, resulting in greater precision and higher quality wind turbine wheels.

[0027] Reference Figures 1 to 3 A roller machine for producing wind turbine impellers, comprising:

[0028] The frame 10 has two sets of rollers 20 installed along the front-back direction. Each set of rollers 20 is equipped with several active pressure rollers 21. The unshaped fan wheel body can be placed on the two sets of rollers 20 and supported by the active pressure rollers 21.

[0029] A drive motor 30 is arranged at the bottom of the frame 10. The drive motor 30 is connected to two sets of rollers 20 and is used to drive the two sets of rollers 20 to rotate in the same direction.

[0030] A movable frame 40 is arranged on the frame 10. An auxiliary shaft 50 is provided on the movable frame 40. Several freely rotatable driven pressure rollers 51 are pivotally connected to the auxiliary shaft 50. A drive cylinder 41 for driving the movable frame 40 to move is arranged on the frame 10.

[0031] A fixed side frame is provided on one side above the roller 20, and a movable side frame is provided on the other side above the roller 20. A feed drive is connected to the movable side frame.

[0032] When the unshaped wind turbine wheel is placed on the two sets of rollers 20, the wheel ring of the unshaped wind turbine wheel is supported by the active pressure roller 21. The drive cylinder 41 can drive the movable frame 40 to move, thereby moving the driven pressure roller 51 to abut against the surface of the wheel ring of the unshaped wind turbine wheel. The central angle formed by the three contact points formed when the two sets of active pressure rollers 21 and driven pressure roller 51 abut against the wheel ring is greater than 180 degrees.

[0033] During production, the pre-assembled but unformed wind turbine wheel is placed on two sets of rollers. The feed drive then presses all blades towards the fixed side frame via the moving fixed side frame, ensuring the blades are aligned. Simultaneously, the position of the wheel ring is manually adjusted so that it is precisely positioned on the surface of the driving pressure roller 21. The drive cylinder 41 and drive motor 30 are then activated. The drive cylinder 41 moves the movable frame 40, causing the driven pressure roller 51 to press against the wheel ring surface. The drive motor 30 rotates the roller 20 and the driving pressure roller 21, thereby rotating the wind turbine wheel. This ensures that the edge of the wheel ring rotates at a uniform and continuous speed against the driving pressure roller 21. The pressure roller 21 and the driven pressure roller 51 abut against each other. The driving cylinder 41 gradually increases the applied force and feed, so that the driven pressure roller 51 continuously squeezes the edge of the wheel ring, causing the edge of the wheel ring to deform and thus completing the assembly and fixation. During this process, when the force applied by the driving cylinder 41 exceeds the specified value, it means that the squeezing of the wheel ring has been completed. At this time, the driving cylinder 41 resets and the driving motor 30 stops, making it convenient to remove the completed wind turbine wheel body. In this way, the production process is standardized. The force of squeezing and deforming the wheel ring is controlled by the driving cylinder 41, which is more precise and results in higher quality wind turbine wheel bodies.

[0034] In this design, the movable frame 40 can be arranged in various ways. For example, the movable frame 40 can be pivotally connected to the top of the frame 10 at its center, the auxiliary shaft 50 can be arranged at the front end of the movable frame 40, a drive mating plate 42 can be provided at the rear end of the movable frame 40, and the drive cylinder 41 can be arranged at the rear side of the frame 10, with the output end of the drive cylinder 41 located below the drive mating plate 42 and able to abut against the bottom surface of the drive mating plate 42. This method arranges the movable frame 40 as a seesaw structure, and the drive cylinder 41 lifts the rear side of the movable frame 40, thereby causing the auxiliary shaft 50 and the driven pressure roller 51 at the front end of the movable frame 40 to swing downwards until they abut against the surface of the wheel ring.

[0035] Further optimization, to facilitate additional manual operation, it is preferable that the front end of the movable frame 40 is also provided with an extension handle 70. This allows for additional feed and pressure application during the production of some wind turbine wheels if the deformation of the wheel ring is deemed insufficient. It also facilitates the user's ability to reset the movable frame 40 via the extension handle 70. Further optimization, the movable frame 40 preferably includes a left frame plate and a right frame plate. The two ends of the auxiliary shaft 50 are respectively connected to the front ends of the left and right frame plates, and the drive mating plate 42 is respectively connected to the top of the rear ends of the left and right frame plates. A balance plate 71 is mounted on the top of the front ends of the left and right frame plates, and the extension handle 70 is arranged on the surface of the balance plate 71. This allows the force applied to the extension handle 70 to be evenly distributed across the entire movable frame 40, maintaining a balanced force distribution. To facilitate the reset of the movable frame 40, a reset torsion spring is preferably provided between the movable frame 40 and the frame 10.

[0036] To further optimize the design and facilitate the positioning of the wheel rings and ensure more standardized deformation, it is preferable that both the driving pressure roller 21 and the driven pressure roller 51 are provided with annular grooves 60. The wheel rings on the unshaped fan wheel body are inserted into the annular grooves 60. During production, the operator adjusts the position of the wheel rings so that they fall into the annular grooves 60. In this case, when the wheel rings are squeezed and deformed, the deformation of the wheel rings will be in the direction restricted by the annular grooves 60.

[0037] In another embodiment, the movable frame 40 can be arranged as follows: a support frame is provided on the top of the frame 10, the drive cylinder 41 is arranged on the top of the support frame with the output end of the drive cylinder 41 facing the surface of the frame 10, the movable frame 40 is arranged on the support frame and located below the drive cylinder 41, and the movable frame 40 is fixedly connected to the output end of the drive cylinder 41.

[0038] In this scheme, there are many ways to connect the drive motor 30 to the two rollers 20. For example, in Embodiment 1, the ends of both rollers 20 are provided with a first gear 22, and the two first gears 22 mesh with each other through a second gear. One of the rollers 20 is also provided with a first sprocket 23. The drive motor 30 is connected to the first sprocket 23 through a chain 80. In this way, the drive motor 30 drives the first sprocket 23 to rotate through the chain 80, thereby driving the roller 20 with the first sprocket 23 to rotate. The roller 20 then meshes with the second gear through the first gear 22, thereby meshing with the first gear 22 on the other roller 20, thus driving the other roller 20 to rotate in the same direction.

[0039] Alternatively, in a second embodiment, a second sprocket is provided on each of the two rollers 20, and the drive motor 30 is synchronously connected to the two second sprockets via a drive chain.

[0040] Alternatively, in Embodiment 3: the end of the drive motor 30 is provided with a drive gear, and the ends of the two rollers 20 are each provided with a driven gear. The drive gear meshes with two sets of gearboxes, and the two sets of gearboxes mesh with two driven gears respectively.

[0041] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
