Description

Technical Field

[0001] This utility model relates to the field of blade processing technology, specifically to a dynamically adjustable blade scraper mechanism. Background Technology

[0002] As the core component for capturing wind energy, the manufacturing precision of wind turbine blades directly determines the overall power generation efficiency and operation and maintenance costs. Among them, the bonding process between the blade web and the shell is a critical step. The two need to be integrated and connected by high-performance structural adhesive. The uniformity, thickness and bonding strength of the adhesive layer directly affect the blade's ability to resist wind loads and fatigue. If the bonding quality is substandard, it may cause abnormal noise and vibration during blade operation, or even lead to cracking of the adhesive layer, delamination of the structure, or even major safety accidents such as blade breakage.

[0003] Existing blade adhesive scrapers on the market mostly rely on manual hand tools to apply adhesive to designated positions during adjustment. This operation method is highly dependent on the worker's experience, and it is difficult to accurately control parameters such as the amount of adhesive applied, uniformity, and coating thickness. This leads to problems such as adhesive waste, insufficient adhesive, and fluctuations in coating thickness, which affect the overall service life of the blade. To address these issues, we propose a dynamically adjustable blade adhesive scraper mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a dynamically adjustable blade scraper mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dynamically adjustable blade scraper mechanism, comprising a base, with guide grooves formed in the middle of both the front and rear sides of the base, a movable seat provided outside the base, the movable seat being slidably connected to the two sets of guide grooves via two sets of guide sliders, a linear actuator mounted at the top center of the movable seat, a cross plate mounted at the output end of the linear actuator, guide posts mounted on both the front and rear sides of the linear actuator, two sets of guide holes formed on the cross plate, the two sets of guide posts passing through the two sets of guide holes, mounting seats mounted at the bottom of both ends of the cross plate, scrapers mounted at the lower ends of the mounting seats, and mounting top plates mounted at the top of the scrapers, the mounting top plates being embedded inside the mounting seats and connected to the mounting seats via locking bolts, and a transverse drive assembly provided at the bottom of the base.

[0006] As a further preferred embodiment of this technical solution, the lateral drive assembly includes rotating seats fixed on the left and right sides of the bottom end of the base. Each of the two rotating seats is rotatably connected to a lead screw. A drive motor is installed on the side end of the base, and the output end of the drive motor is connected to the end of the lead screw. A threaded sleeve is installed in the middle of the bottom end of the movable seat, and the threaded sleeve and the lead screw form a threaded connection.

[0007] As a further preferred embodiment of this technical solution, a control switch is installed on one side of the lower end of the base, and the output terminal of the control switch is electrically connected to the linear driver and the drive motor through a wire.

[0008] As a further preferred embodiment of this technical solution, the scraper is made of polyurethane or wear-resistant rubber.

[0009] As a further preferred embodiment of this technical solution, the drive motor is a servo motor or a stepper motor.

[0010] As a further preferred embodiment of this technical solution, the inner walls of the two sets of guide holes on the crossbeam are fully fitted with the outer walls of the two sets of guide posts, and the crossbeam is slidably connected to the two sets of guide posts through the two sets of guide holes.

[0011] This utility model provides a dynamically adjustable blade scraper mechanism, which has the following beneficial effects: 1. This utility model features a horizontally movable seat installed on the outside of the base, with a liftable crossbeam mounted on the movable seat. Two sets of scraper blades can be quickly installed inside the mounting seats at both ends of the crossbeam using locking bolts. This facilitates the disassembly and replacement of the scraper blades, allowing for rapid replacement according to the blade model. A linear actuator then drives the crossbeam to move up and down, with the guide column and guide hole ensuring smooth up-and-down movement. This allows the scraper blades to dynamically adjust their height under the drive of the crossbeam, ensuring rapid height adjustment to adapt to different adhesive layer thicknesses and effectively avoiding problems such as adhesive waste, insufficient adhesive, and fluctuations in coating thickness.

[0012] 2. This utility model has a rotatable lead screw installed at the bottom of the base. The drive motor drives the lead screw to rotate, which causes the threaded sleeve at the bottom of the movable seat to move axially along the lead screw. This causes the movable seat to slide laterally on the base, thereby adjusting the lateral position of the scraper and effectively improving the lateral accuracy of the scraper, thus effectively reducing manual intervention.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0017] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0018] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0019] This utility model provides a technical solution: such as Figures 1 to 3As shown, in this embodiment, a dynamically adjustable blade scraper mechanism includes a base 1. Guide grooves 2 are provided in the middle of both the front and rear sides of the base 1. A movable seat 3 is provided on the outside of the base 1. The movable seat 3 is slidably connected to the two sets of guide grooves 2 through two sets of guide sliders 4. A linear actuator 5 is installed at the middle of the top of the movable seat 3. A cross plate 6 is installed at the output end of the linear actuator 5. Guide posts 7 are installed on both the front and rear sides of the linear actuator 5. Two sets of guide holes 8 are provided on the cross plate 6. The two sets of guide posts 7 pass through the two sets of guide holes 8. Mounting seats 9 are installed at the bottom of both ends of the cross plate 6. Scrapers 10 are installed at the lower end of the mounting seats 9. Mounting top plates 11 are installed at the top of the scrapers 10. The mounting top plates 11 are embedded in the mounting seats 9 and connected to the mounting seats 9 through locking bolts 12. A transverse drive assembly is provided at the bottom of the base 1.

[0020] By installing a laterally movable seat 3 on the outside of the base 1, and installing a liftable crossbeam 6 on the movable seat 3, two sets of scraper blades 10 can be quickly installed inside the mounting seats 9 at both ends of the crossbeam 6 using locking bolts 12. This facilitates the disassembly and replacement of the scraper blades 10, allowing them to be quickly replaced according to the blade model. The linear actuator 5 then pushes the crossbeam 6 up and down, and the guide post 7 cooperates with the guide hole 8 to ensure the smooth up and down movement of the crossbeam 6. This allows the scraper blades 10 to dynamically adjust their height under the drive of the crossbeam 6, ensuring that the scraper blades 10 can be quickly adjusted to adapt to different adhesive layer thicknesses and effectively avoiding problems such as adhesive waste, insufficient adhesive, and fluctuations in coating thickness.

[0021] In other embodiments, the lateral drive assembly includes rotating seats 13 fixed on the left and right sides of the bottom end of the base 1. Both rotating seats 13 are rotatably connected to lead screws 14. A drive motor 15 is installed on the side end of the base 1.

The threaded sleeve 16 and the lead screw 14 form a threaded connection. By installing a rotatable lead screw 14 at the bottom of the base 1, the drive motor 15 drives the lead screw 14 to rotate, causing the threaded sleeve 16 at the bottom of the movable seat 3 to move axially along the lead screw 14, thereby driving the movable seat 3 to slide laterally on the base 1, realizing the lateral position adjustment of the scraper 10, and effectively improving the lateral accuracy of the scraper 10, thus effectively reducing manual intervention.

[0022] In other embodiments, a control switch 17 is installed on one side of the lower end of the base 1, and the output terminal of the control switch 17 is electrically connected to the linear driver 5 and the drive motor 15 through a wire; This design allows the control switch 17 to receive external commands to control the start, stop, direction, and speed of the linear driver 5 and the drive motor 15, enabling dynamic adjustment of the height and lateral position of the scraper 10. It also allows for remote or programmed control, improving production efficiency.

[0023] In other embodiments, the scraper 10 is made of polyurethane rubber; This design allows the scraper 10 to be made of flexible polyurethane material, which can adapt to the curved surface of the blade during the scraping process, while reducing damage to the blade surface and making the scraping more uniform.

[0024] In other embodiments, the drive motor 15 is a servo motor or a stepper motor; Because servo motors or stepper motors can receive pulse signals for precise control, they can achieve accurate positioning of the movable seat 3 and can be integrated with PLCs or CNC systems to achieve automated production.

[0025] In other embodiments, the inner walls of the two sets of guide holes 8 on the cross plate 6 are fully fitted with the outer walls of the two sets of guide posts 7, and the cross plate 6 forms a sliding connection with the two sets of guide holes 8 and the two sets of guide posts 7 through the two sets of guide holes 8; This design prevents the crossbeam 6 from swaying when it moves up and down along the two sets of guide columns 7, thereby improving the stability of the crossbeam 6 when it moves up and down.

[0026] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.
