Description

Technical Field

[0001] The invention relates to the technical field of uncoilers, and in particular to a carbon beam uncoiler. Background Art

[0002] In the past, wind turbine blades were mainly made of glass fiber materials. With the development of technology, carbon fiber materials began to be used in blade beams due to their excellent mechanical properties and process properties.

[0003] In the application process of carbon beams, various lengths of carbon fiber sheets are required according to the different specifications of wind turbine blades. Carbon fiber materials are made into rolls according to different width specifications when leaving the factory, and are packaged and transported in the form of rolls. When the carbon fiber materials arrive at the blade manufacturer, they need to be unrolled and chamfered. Due to the excellent mechanical properties of carbon fiber materials, the rolled carbon fiber materials will explode directly after the cable ties are cut without any equipment assistance, which is extremely dangerous. This urgently requires the development of an unwinding machine suitable for carbon fiber materials. Summary of the invention

[0004] To this end, it would be advantageous for the present invention to provide a carbon beam uncoiler that can safely and efficiently unwind a rolled carbon fiber material.

[0005] To achieve the above-mentioned purpose, the present invention provides a carbon beam decoiler, which includes a frame, a rotary drive device, an inner ring lifting device and an outer ring lifting device, wherein the rotary drive device is installed on the frame, the inner ring lifting device is transmission-connected to the rotary drive device and is configured to fix the carbon beam from the inside, and the outer ring lifting device is installed on the frame and is configured to limit the carbon beam from the outside.

[0006] In the present invention, the arrangement of the inner ring lifting device and the outer ring lifting device enables the carbon beam to be fixed and limited from the inside and the outside respectively, so that the inner ring and the outer ring of the rolled carbon beam (also called carbon coil) loaded into the carbon beam uncoiler are pressed at the same time, avoiding the carbon beam from bursting after the cable tie is cut, and the operation is simple, safe and efficient.

[0007] Furthermore, the above-mentioned carbon beam decoiler also includes an end surface fixing fixture for fixing the carbon beam.

[0008] By providing an end face fixing fixture, the end face of the carbon beam can be fixed, further improving production safety.

[0009] Furthermore, the above-mentioned carbon beam decoiler also includes a tail clamping device for fixing the tail of the inner ring of the carbon beam, and the tail clamping device is installed on the inner ring lifting device.

[0010] Through the setting of the tail clamping device, the tail of the inner ring of the carbon beam can be fixed on the inner ring lifting device, further improving production safety.

[0011] Furthermore, the rotation drive device includes a motor and a gear transmission device driven by the motor.

[0012] Still further, the inner ring lifting device includes a mounting base, a connecting plate, a plurality of inner ring lifting beams, a plurality of connecting rods, and an inner ring lifting electric cylinder. Among them, the mounting base is in transmission connection with the gear transmission device, the connecting plate is fixed to the mounting base through the connecting columns thereon. The plurality of inner ring lifting beams are located between the mounting base and the connecting plate and are respectively pivotally connected to the connecting plate. Each connecting rod is respectively pivotally connected to the mounting base and a corresponding inner ring lifting beam. The inner ring lifting electric cylinder is installed on the connecting plate and drives to connect one of the inner ring lifting beams, so that the inner ring lifting device can be converted between the retracted initial position and the extended lifting position. And the tail clamping device is installed on the one of the inner ring lifting beams.

[0013] Through the above structural settings, during the process of fixing the carbon beam before uncoiling, the outer extension action of the inner ring lifting electric cylinder can drive one of the inner ring lifting beams connected thereto to pivot counterclockwise relative to the connecting plate to tighten the inner ring of the carbon beam, and at the same time drive the corresponding connecting rod to rotate counterclockwise, and then drive the mounting base pivotally connected to the connecting rod to rotate counterclockwise, so that the other connecting rods rotate counterclockwise, thereby enabling the other inner ring lifting beams to simultaneously tighten the inner ring of the carbon beam; enabling the inner ring lifting device to be driven to rotate by the gear transmission device during the uncoiling process, and then driving the carbon beam tightened by it to rotate together with itself for uncoiling.

[0014] Even further, the mounting base has a mounting substrate, a central transmission shaft connected to the connecting plate, and a plurality of pin shafts for respectively connecting the plurality of connecting rods. Among them, a plurality of extension parts are axially and uniformly distributed on the mounting substrate, and a carbon beam limiting block is installed on each extension part.

[0015] Through the above structural settings, the mounting substrate, the connecting plate, and the connecting rods can transmit the rotational force through the central transmission shaft and thus rotate together; the setting of the carbon beam limiting block enables the position to be determined when installing the carbon beam.

[0016] Also further, when the inner ring lifting beam is in the retracted initial position, the inner ring lifting electric cylinder is in the retracted state; when the inner ring lifting beam is in the extended lifting position, the inner ring lifting electric cylinder is in the lifting state.

[0017] Once again further, each inner ring lifting beam has an arc-shaped lifting head, and a position sensor or a pressure sensor is installed on the arc-shaped lifting head.

[0018] By setting up the sensors, it is possible to sense whether the inner ring lifting device tightly presses the inner ring of the carbon beam, ensuring that the uncoiler is started only after the inner ring of the carbon beam is pressed tightly.

[0019] Furthermore, the outer ring lifting device includes an outer ring lifting electric cylinder and an outer ring lifting assembly. Among them, the outer ring lifting assembly includes a support seat with one end movably connected to the frame, a driving pulley, a driven pulley, a motor for driving the driving pulley, and a conveyor belt connecting the driving pulley and the driven pulley. The outer ring lifting electric cylinder is installed on the frame and connected to the other end of the support seat, so as to be able to drive the outer ring lifting assembly to move between the initial landing position and the upward lifting position. When in the upward lifting position, the conveyor belt is in sliding contact with the outer ring of the carbon beam.

[0020] Through the above structural settings, the outer ring lifting device can make its conveyor belt in sliding contact with the carbon beam and press the carbon beam tightly by means of the action of the outer ring lifting electric cylinder.

[0021] Furthermore, a contact sensor is installed on the conveyor belt to ensure that the conveyor belt is always in contact with the outer ring of the carbon beam.

[0022] In addition, it includes a pair of slide rails and two frames. Each frame is correspondingly provided with a rotary drive device, an inner ring lifting device and an outer ring lifting device. Among them, the two frames are slidably installed back-to-back on the pair of slide rails and connected together via an intermediate connecting beam. Each frame has a carbon beam installation opening on the outer side and an installation back plate on the inner side. The rotary drive device is installed on the installation back plate facing the carbon beam installation opening.

[0023] Through the above structural settings, the two uncoilers are designed in parallel with the support of the slide rails, avoiding the slow operation efficiency caused by the inevitable intermediate loading and unloading of a single uncoiler, reducing the intermediate loading and unloading time, and improving the operation efficiency.

[0024] These aspects and other aspects of the present invention will be more clearly elaborated by referring to the embodiments described below. Brief Description of the Drawings

[0037] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0038] In this article, the directional representations used to explain the structure and / or movement of each part of the disclosed embodiments, such as "front", "rear", "left", "right", "inner", "outer", etc., are not absolute but relative. When each part of the disclosed embodiments is in the position shown in the figures, these representations are appropriate, and if the position or reference system of the disclosed embodiments changes, these representations will also change according to the change of the position or reference system of the disclosed embodiments.

[0039] The "carbon beam" referred to in this article is a roll of carbon fiber board, which is the material prepared for producing the main beam of the wind turbine blade, and needs to be unrolled before the subsequent production of the blade main beam, such as before carbon beam chamfering production.

[0040] The decoiler of the carbon beam according to a specific embodiment of the present invention is as Figures 1 to 8 shown. As Figures 1 to 3 shown, in this embodiment, the decoiler of the carbon beam includes a frame 1 having a carbon beam mounting opening 11 on the outer side and a mounting back plate 13 on the inner side, a rotary drive device including a motor 31 and a gear transmission device 32 driven by the motor, an inner ring lifting device 5, and an outer ring lifting device 7. As Figure 3 shown, the gear transmission device 32 is mounted on the frame 1; the inner ring lifting device 5 is in transmission connection with the gear transmission device 32 and is arranged to be able to fix the carbon beam 9 from the inside; the outer ring lifting device 7 is mounted on the bottom of the frame 1 and is arranged to be able to limit the carbon beam 9 from the outside.

[0041] Again, as Figures 1 to 3 shown, the outer ring lifting device 7 includes an outer ring lifting electric cylinder 70 and an outer ring lifting assembly 72. Among them, the outer ring lifting assembly 72 includes a support 71 whose one end is movably connected to the frame 1, a driving pulley 73 mounted on the support 71, a driven pulley 75, a motor 77 for driving the driving pulley 73, and a conveyor belt 79 connecting the driving pulley 73 and the driven pulley 75. As Figure 2 clearly shown, the outer ring lifting electric cylinder 70 is mounted on the frame 1 and is connected to the other end of the support 71, so as to be able to drive the outer ring lifting assembly 72 to move between the initial landing position (see Figure 1 , Figure 2 and Figure 3 ) and the upward lifting position (not shown in the figure). At this upward lifting position, the conveyor belt 79 is in sliding contact with the outer ring of the carbon beam 9, so as to press the carbon beam 9 for limiting. Preferably, a contact sensor (not shown in the figure) is installed on the conveyor belt 79 to ensure that the conveyor belt 79 is always in contact with the outer ring of the carbon beam 9.

[0042] As Figure 4 and Figure 5 shown, the inner ring lifting device 5 includes a mounting seat 50, a connecting plate 52, four inner ring lifting beams 54, four connecting rods 56, and an inner ring lifting electric cylinder 58. As Figure 6 shown, the mounting seat 50 has a mounting substrate 503 in transmission connection with the gear transmission device 32, a central transmission shaft 502 connected to the connecting plate 52, and four pin shafts 506 for respectively connecting the four connecting rods 56. And, a plurality of extension parts 508 evenly distributed axially are provided on the mounting substrate 503, and a carbon beam limiting block 509 is installed on each extension part 508. Preferably, the mounting seat 50 further includes a fixing plate 504 at the other end of the four pin shafts 506 to strengthen the structure.

[0043] As Figure 5 shown and referring to Figure 4, the connecting plate 52 is fixed to the mounting seat 50 through the connecting columns 520 thereon. At the same time, the fixing plate 504 of the mounting seat 50 is also fixed to the connecting plate 52; the four inner ring lifting beams 54 are located between the mounting seat 50 and the connecting plate 52 and are respectively pivotally connected to the connecting plate 52 for rotatable connection; each connecting rod 56 is respectively pivotally connected to a corresponding pin shaft 506 and a corresponding inner ring lifting beam 54; the inner ring lifting electric cylinder 58 is installed on the connecting plate 52 or on the central transmission shaft 502 passing through the connecting plate 52 and drives to connect one of the inner ring lifting beams 54, so that the inner ring lifting device 5 can be in the initial retracted position (see Figure 7 ), and the extended lifting position (see Figure 8 ). It should be noted that when the inner ring lifting beam 54 is in the initial retracted position, the inner ring lifting electric cylinder 58 is in the retracted state; when the inner ring lifting beam 54 is in the extended lifting position, the inner ring lifting electric cylinder 58 is in the lifting state.

[0044] As shown in Figure 5 and Figure 6 , and referring to Figure 7 and Figure 8 , each inner ring lifting beam 54 has an arc-shaped lifting head 540, and a position sensor or a pressure sensor (not shown in the figure) is installed on the arc-shaped lifting head 540, so as to be able to sense whether the inner ring of the inner ring lifting device 5 presses tightly against the inner ring of the carbon beam 9, and ensure that the inner ring of the carbon beam 9 is pressed tightly before starting the entire carbon coil uncoiler. Again, as shown in Figure 5 , the movable connection point of the connecting rod 56 and the inner ring lifting beam 54 is close to the arc-shaped lifting head 540, while the movable connection point of the connecting plate 52 and the inner ring lifting beam 54 is close to the tail part 542 of the lifting frame.

[0045] The carbon beam uncoiler according to another specific embodiment of the present invention is as shown in Figures 9 to 11 . The carbon beam uncoiler of this embodiment includes two Figures 1 to 3 shown carbon beam uncoilers. Specifically, as shown in Figure 9 , and referring to Figure 10 and Figure 11 , in this embodiment, the carbon beam uncoiler includes a pair of slide rails 2 and two frames 1. Each frame 1 is correspondingly provided with a rotary drive device having a motor (not shown in this figure) and a gear transmission device 32, an inner ring lifting device 5 and an outer ring lifting device 7. Among them, the two frames 1 are slidably installed back-to-back on the pair of slide rails 2 and are connected together via an intermediate connecting beam 12. The two uncoilers are designed in parallel, reducing the intermediate loading and unloading time and improving the operation efficiency.

[0046] In addition, in this embodiment, as shown in Figure 10As shown, the carbon beam decoiler further includes an end face fixing fixture 4 for fixing the end face of the carbon beam 9 and a tail clamping device 6 for fixing the tail of the inner ring of the carbon beam 9. In this embodiment, the tail clamping device 6 is installed on one of the inner ring lifting beams 54 of the inner ring lifting device 5. These structures further ensure the shape retention of the carbon beam 9, avoid the explosion of the carbon beam 9, and improve the production safety. It should be understood that in Figures 1 to 3 the specific embodiment shown, the above-mentioned end face fixing fixture 4 and tail clamping device 6 may also be included.

[0047] It should be noted that although the number of the above-mentioned inner ring lifting beams 54 and connecting rods 56 is four, their number is not limited to four. As long as their numbers are the same, they can be three or more. In addition, although the number of the extension parts 508 and carbon beam limit blocks 509 on the mounting seat 50 is four in this embodiment, the number can also be changed in other embodiments.

[0048] It should be understood that the carbon beam decoiler can be equipped with a controller to control electrical components such as electric cylinders, motors, and sensors thereon, so as to automatically control the decoiling.

[0049] Next, refer to Figures 1 to 3 and in combination with Figures 4 to 8 to introduce the working process of the carbon beam decoiler in this embodiment:

[0050] First, the coiled carbon beam 9 is lifted into the frame 1 of the carbon beam decoiler through the carbon beam installation opening 11 of the frame 1 by a cantilever crane, and the end face of the carbon beam 9 is fixed by the end face fixing fixture 4 to limit the end face displacement;

[0051] The tail inside the carbon beam 9 is fixed by the tail clamping device 6 to prevent the carbon beam 9 from expanding inward;

[0052] Then, the inner ring lifting cylinder 58 of the inner ring lifting device 5 drives the inner ring lifting beam 54 to lift the inner ring of the carbon beam 9. During this process, the movement of the connecting rod 56 movably connected to the inner ring lifting beam 54 drives the other three connecting rods 56 to move, pushing the corresponding other three inner ring lifting beams 54 to synchronously lift the inner ring of the carbon beam 9 until the established stroke is reached, so that all four inner ring lifting beams 54 tightly press against the inner ring of the carbon beam 9;

[0053] The arc-shaped lifting head 540 of the inner ring lifting beam 54 is equipped with a position sensor or a pressure sensor, so that each inner ring lifting beam 54 finally tightly presses against the inner ring of the carbon beam 9 to prevent a gap from existing between the inner ring lifting beam 54 and the inner ring of the carbon beam 9;

[0054] The outer ring of the carbon beam 9 is limited by the outer ring lifting device 7 at the lower part of the carbon beam uncoiler to prevent outward explosion. The outer ring lifting device 7 is slowly driven upward step by step by the outer ring lifting electric cylinder 70 until the conveyor belt 79 thereon presses tightly against the outer ring of the carbon beam 9.

[0055] After the end face, inner ring and outer ring of the carbon beam 9 are all fixed, the gear transmission device 32 of the carbon beam uncoiler is driven to rotate by the motor 31, so that the inner ring lifting device 5 drives the carbon beam 9 to rotate automatically and feed forward.

[0056] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative concept of the present invention, those skilled in the art can make various changes and improvements to the above structure, including combinations of the technical features disclosed or claimed here alone, and other combinations that obviously include these features.
