Description

Technical Field

[0001] The present invention relates to the technical field of forming pretreatment of polyurethane resin pultruded plates, and specifically to a forming pretreatment device for polyurethane resin pultruded plates used in wind turbine blades. Background Technique

[0002] As a key component of a wind turbine generator set, in order to meet the design requirements of large size, light weight and high strength, polyurethane resin-based composite materials have gradually become important materials for wind turbine blade manufacturing due to their excellent mechanical properties, fatigue resistance and forming efficiency. Among them, polyurethane pultruded plates are widely used in load-bearing structures such as blade main beams and webs due to their high fiber content, dimensional stability and continuous forming advantages.

[0003] The forming pretreatment operation of pultruded plates is mainly to disperse and impregnate fiber bundles. At present, for the wire bundle dispersion operation and impregnation operation of the forming pretreatment device for polyurethane resin pultruded plates used in wind turbine blades, generally, the fiber bundles are dispersed and immersed into an impregnation tank filled with polyurethane resin through dispersion holes in a fixed dispersion plate. However, in this fixed impregnation method, the impregnation cannot achieve high uniformity. The viscosity of polyurethane resin is relatively high, and it is difficult to fully infiltrate fiber reinforcing materials (such as glass fiber and carbon fiber) in the pultrusion process, resulting in pores or poor interfacial bonding inside the plate, which affects the mechanical properties. Summary of the Invention

[0011] Start the telescopic cylinder 2, which drives the sliding block 1 and the sliding block 2 to move up and down along the guide rail 2, so that the sliding block 2 drives the moving guide rail to move up and down synchronously. The moving guide rail drives the driving component, the angle adjustment mechanism and the dispersion plate inside the dipping tank to move up and down synchronously through the guide rail 2, thereby driving the fiber bundle to move up and down within a certain range in the dipping tank, thereby improving the uniformity of its dipping; At the same time, the telescopic cylinder 2 and the telescopic cylinder 1 are started, the slide groove on the moving plate, the roller slides in the slide groove, and the moving guide rail slides inside the sliding block 2, so as to drive the moving guide rail to perform circular reciprocating motion, thereby driving the driving component, angle adjustment mechanism, and dispersion plate inside the dipping tank to perform circular synchronous reciprocating motion, so that the fiber bundle performs circular reciprocating motion of a certain amplitude in the dipping tank, thereby improving the uniformity of its dipping; Furthermore, the driving assembly includes a motor, a belt, a pulley, a bidirectional screw 1, a bidirectional screw 2, a moving block, and a protective shell.

The pulleys drive another set of pulleys to rotate synchronously through the transmission of the belt, and then drive the first double screw and the second double screw to rotate synchronously. Since there are two opposite thread segments on both the first double screw and the second double screw, when the first double screw and the second double screw rotate, the corresponding moving blocks are driven to approach the middle of the motor. When the motor is controlled to rotate in the reverse direction, the outer sides of the corresponding moving blocks are dispersed. Since the moving blocks are fixedly connected to the dispersion plate through the angle adjustment mechanism, the dispersion plate can move synchronously with it, thereby achieving the purpose of automatically adjusting the spacing between the fiber bundles; Further, the fiber bundles pass through a set of the guide rollers and penetrate into the inner side of the dipping tank, are dispersed through the grooves on the dispersion plate, and finally pass out through another set of the guide rollers.

[0027] , start the telescopic cylinder 2 732, the telescopic cylinder 2 732 drives the sliding block 1 733 and the sliding block 2 734 to move up and down along the guide rail 2 736, so that the sliding block 2 734 drives the moving guide rail 735 to move up and down synchronously, and the moving guide rail 735 drives the driving component 6, the angle adjustment mechanism 5, and the dispersion plate 4 inside the dipping tank 2 to move up and down synchronously through the guide rail 2 736, thereby driving the fiber bundle to move up and down within a certain range in the dipping tank 2, thereby improving the uniformity of its dipping; At the same time, the telescopic cylinder 2 732 and the telescopic cylinder 1 724 are started, and the slide groove on the moving plate 725 and the roller 726 slide in the slide groove, and the moving guide rail 735 slides inside the sliding block 2 734, so as to drive the moving guide rail 735 to perform a circular reciprocating motion, thereby driving the driving component 6, the angle adjustment mechanism 5, and the dispersion plate 4 inside the dipping tank 2 to perform a circular synchronous reciprocating motion, so that the fiber bundle performs a circular reciprocating motion of a certain amplitude in the dipping tank 2, thereby improving the uniformity of its dipping; Furthermore, the driving assembly 6 includes a motor 61, a belt 62, a pulley 63, a bidirectional screw 1 64, a bidirectional screw 2 65, a moving block 66, and a protective shell 67. The motor 61 is fixedly connected to the upper side of the connecting frame 737, the protective shell 67 is fixedly connected to the lower inner side of the connecting frame 737, and the bidirectional screw 1 64 and the bidirectional screw 2 65 are rotatably connected to the inner side of the protective shell 67.

[0028] Furthermore, two opposite threaded sections are provided on the bidirectional screw rod 1 64 and the bidirectional screw rod 2 65 , and the outer sides of the threaded sections are threadedly connected with a moving block 66 . A groove corresponding to the moving block 66 is provided on the protective shell 67 , and the moving block 66 is fixedly connected to the base plate 51 .

[0029] Furthermore, the upper sides of the bidirectional screw rod 1 64 and the bidirectional screw rod 2 65 are fixedly connected with pulleys 63 , a belt 62 is transmission-connected between the two sets of pulleys 63 , and one set of pulleys 63 is fixedly connected to the output end of the motor 61 .

[0030] When it is necessary to adjust the spacing between the fiber bundles at various places in the grooves of the inserted dispersion plate 4, the motor 61 is started. The motor 61 drives a set of pulleys 63 to rotate. The pulley 63 drives another set of pulleys 63 to rotate synchronously through the transmission of the belt 62, and then drives the first bidirectional screw 64 and the second bidirectional screw 65 to rotate synchronously. Since there are two sections of opposite threads on both the first bidirectional screw 64 and the second bidirectional screw 65, when the first bidirectional screw 64 and the second bidirectional screw 65 rotate, the corresponding moving blocks 66 are driven to approach the middle of the motor 61. When the motor 61 is controlled to rotate in reverse, the outer sides of the corresponding moving blocks 66 are driven to disperse. Since the moving blocks 66 are fixedly connected to the dispersion plate 4 through the angle adjustment mechanism 5, the dispersion plate 4 can move synchronously with it, thus achieving the purpose of automatically adjusting the spacing between the fiber bundles; Further, the fiber bundles pass through a set of guide rollers 3 and penetrate into the inner side of the dipping tank 2, are dispersed through the grooves on the dispersion plate 4, and finally pass through another set of guide rollers 3 and exit.

[0031] The specific usage mode and function of this embodiment: During use, first, the external fiber bundles are pulled out from the external yarn rack, introduced into the dipping tank 2 through the upper side of a set of guide rollers 3, then the fiber bundles are evenly dispersed and inserted into the grooves on the dispersion plate 4, and finally are led out of the dipping tank 2 through the upper side of another set of guide rollers 3 and connected to the external pultrusion forming die; After the fiber bundles are inserted, pour polyurethane resin into the inner side of the dipping tank 2. When pulling the fiber bundles for dipping operation, there are three motion states for uniform dipping; In the first motion state, the second telescopic cylinder 732 is started. The second telescopic cylinder 732 drives the first sliding block 733 and the second sliding block 734 to move up and down along the second guide rail 736, so that the second sliding block 734 drives the moving guide rail 735 to move up and down synchronously. The moving guide rail 735 drives the drive assembly 6, the angle adjustment mechanism 5, and the dispersion plate 4 inside the dipping tank 2 to move up and down synchronously through the second guide rail 736, and then the fiber bundles can be driven to move up and down within a certain range in the dipping tank 2, improving the uniformity of dipping; In the second motion state, the first telescopic cylinder 724 is started. The first telescopic cylinder 724 drives the moving plate 725 to move left and right along the first guide rail 723, so that the moving plate 725 drives the moving guide rail 735 to move left and right synchronously through the rollers 726 and the fixedly installed block 727, and then drives the drive assembly 6, the angle adjustment mechanism 5, and the dispersion plate 4 inside the dipping tank 2 to move left and right synchronously. Thus, the fiber bundles move left and right within a certain range in the dipping tank 2, improving the uniformity of dipping; In the third motion state, the telescopic cylinder two 732 and the telescopic cylinder one 724 are started simultaneously. Under the action of the sliding groove on the moving plate 725 and the sliding of the roller 726 in the sliding groove, as well as the sliding of the motion guide rail 735 inside the second sliding block 734, the circular reciprocating motion of the motion guide rail 735 is realized. Furthermore, the driving assembly 6, the angle adjustment mechanism 5, and the dispersion plate 4 inside the dipping tank 2 are driven to perform circular synchronous reciprocating motion, enabling the fiber wire bundle to perform circular synchronous reciprocating motion with a certain amplitude in the dipping tank 2, improving the uniformity of its dipping; An external tensioning device for the fiber wire bundle is provided to ensure that the fiber wire bundle is in a taut state during movement; When it is necessary to adjust the spacing between the fiber wire bundles at various positions in the grooves of the dispersion plate 4, the motor 61 is started. The motor 61 drives a set of belt pulleys 63 to rotate. The belt pulleys 63 drive another set of belt pulleys 63 to rotate synchronously through the transmission of the belt 62, and then drive the first bidirectional screw 64 and the second bidirectional screw 65 to rotate synchronously. Since there are two opposite thread segments on both the first bidirectional screw 64 and the second bidirectional screw 65, when the first bidirectional screw 64 and the second bidirectional screw 65 rotate, the corresponding moving blocks 66 are driven to approach the middle of the motor 61. When the motor 61 is controlled to rotate in the reverse direction, the outer sides of the corresponding moving blocks 66 are driven to disperse. Since the moving blocks 66 are fixedly connected to the dispersion plate 4 through the angle adjustment mechanism 5, the dispersion plate 4 can move synchronously with it, thus achieving the purpose of automatically adjusting the spacing between the fiber wire bundles; When it is necessary to adjust the direction of the grooves on the dispersion plate 4 to change the angle at which the fiber wire bundle passes through the dispersion plate 4 in the face of different situations, the staff rotates the locking rod 55 to separate the locking rod 55 from the rotating disk 56. After unlocking the rotating disk 56, by pushing the operating rod 57, and then according to the angle scale line on the rotating ring 53, the rotation angles of the rotating disk 56 and the mounting block 58 can be accurately controlled. The dispersion plate 4 is driven to rotate synchronously through the connecting shaft 59. When the angle adjustment is completed, the rotating disk 56 is locked again through the locking rod 55, thus realizing the fixation of the dispersion plate 4.
