The machine base is connected to the connecting seat, and a drive component that drives the connecting seat to move is provided between the machine base and the collection seat.

[0007] Using the above technical solution, the drive component moves the base within the directional slide, thereby pulling the winding steel strip. Simultaneously, the winding component feeds and releases the winding steel strip. Under the directional guidance of the scraper guide seat, the winding steel strip unfolds and straightens to the same length as the forming mold and adheres to the surface of the tower body, according to the length of the FRP tower body forming mold. Thus, during the rotation of the tower body driven by the mold, the winding steel strip scrapes off excess resin glue from the surface of the tower body in one go, ensuring flatness. At the same time, the scraped resin glue drips into the collection seat for storage.

[0008] When the drive assembly and the winding assembly work together to wind up the steel strip, the scraper guide seat scrapes and cleans the resin adhesive on the surface of the steel strip.

[0016] As a preferred embodiment of this utility model, the bottom front side of the liquid storage seat is connected to a drain head, and an automatic switching valve is connected to the drain head.

[0017] By adopting the above technical solution, opening the automatic switch valve allows the resin liquid stored in the reservoir to be discharged through the drain pipe.

[0018] As a preferred technical solution of this utility model, the bottom of the collecting seat is provided with support seats on both the left and right sides.

[0019] By adopting the above technical solution, the support base provides support for the entire equipment.

[0020] As a preferred embodiment of this utility model, the bottom of the collecting seat is provided with both the left and right sides inclined downwards towards the center.

[0021] The above technical solution facilitates the flow of resin liquid dripped into the collection seat along the inclined surface to the drain pipe.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] 1. This fiberglass tower resin scraping equipment uses a drive assembly to move the base within a directional slide, thereby pulling the winding steel strip. Simultaneously, the winding assembly feeds and releases the winding steel strip. Under the directional guidance of the scraping guide seat, the winding steel strip unfolds and straightens to the same length as the molding mold and adheres to the tower surface, according to the length of the fiberglass tower molding mold. Thus, during the rotation of the tower body driven by the mold, compared to existing technologies, the excess resin on the tower surface is scraped off in one go using the winding steel strip, ensuring flatness. At the same time, the scraped resin drips into the collection seat for storage.

[0024] When the drive assembly and the winding assembly work together to wind up the steel strip, the scraper guide seat scrapes and cleans the resin adhesive on the surface of the steel strip.

[0025] 2. The resin scraping equipment for the fiberglass tower body discharges the resin liquid that drips into the collection seat into the storage seat through the drain pipe. By opening the automatic switch valve, the resin liquid stored in the storage seat can be discharged through the drain pipe. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1 to 4The resin scraping device for the FRP tower body in this embodiment mainly includes a collection seat 1, a winding assembly, a scraping guide seat 4, a winding steel strip 5, a directional slide seat 6, a machine base 7, a drive assembly, a drain pipe 13, a storage seat 14, a drain head 15, an automatic switching valve 16, and a support seat 12.

[0033] The collecting seat 1 is located below the fiberglass tower body molding mold and serves as a resin adhesive collection component. The collecting seat 1 is rectangular in shape and is made of high-strength metal material (such as stainless steel) to ensure its structural stability and corrosion resistance. The bottom left and right sides of the collecting seat 1 are inclined downwards towards the center. This design facilitates the resin adhesive dripping into the collecting seat 1 to flow along the inclined surface to the drain pipe 13.

[0034] The winding assembly is located on the front side of the collecting base 1, including a servo motor 2 and a winding reel 3. The servo motor 2 is fixedly installed on the front surface of the left side end of the collecting base 1, and its output end is connected and fixed to the winding reel 3. The servo motor 2 is a high-performance, high-precision model that can accurately control forward and reverse rotation and speed. The winding reel 3 is a cylindrical structure made of metal material (such as aluminum alloy), which has a certain strength and rigidity. The winding steel strip 5 is wound and fixed to the outside of the winding reel 3. The winding steel strip 5 is made of high-strength, wear-resistant metal strip (such as stainless steel strip), and its width is designed according to the actual size of the fiberglass tower body and the scraping requirements.

[0035] The scraper guide seat 4 is fixed to the middle of the upper surface of the collecting seat 1. Its function is to guide the winding steel strip 5 so that the winding steel strip 5 can move along a predetermined path. The scraper guide seat 4 is provided with a guide groove inside. The size of the guide groove matches the thickness and width of the winding steel strip 5 to ensure that the winding steel strip 5 will not deviate during movement. At the same time, when the drive assembly and the winding assembly work together to wind the winding steel strip 5, the scraper guide seat 4 can scrape and clean the resin adhesive on the surface of the winding steel strip 5.

[0036] The directional slide 6 is fixed to the front surface of the collecting seat 1. It has a groove inside. The base 7 is slidably installed in the groove. The base 7 is connected and fixed to the connecting seat 10. The connecting seat 10 is fixed to the other end of the winding steel strip 5. The base 7 is made of metal material and has a certain weight and stability to ensure that it will not shake during movement. The groove surface of the directional slide 6 is precision machined and has a low surface roughness to reduce the friction when the base 7 moves.

[0037] A drive assembly is provided between the base 7 and the collection seat 1. The drive assembly is used to drive the base 7 to move within the directional slide 6. It includes a rack 11, a drive motor 8, and a gear plate 9. The rack 11 is fixed to the front surface of the collection seat 1 and is made of high-strength metal material. The tooth shape and size of the rack 11 match the gear plate 9. The drive motor 8 is fixedly installed on the lower surface of the base 7. It is a high-performance DC motor or AC motor that can provide sufficient power. The output end of the drive motor 8 is fixed with a gear plate 9 that meshes with the rack 11. The gear plate 9 is made of metal material and has been quenched to improve its hardness and wear resistance.

[0038] The bottom center of the collecting seat 1 is connected to a drain pipe 13, which is made of metal or plastic and has a certain degree of flexibility and corrosion resistance. The other end of the drain pipe 13 is connected to a storage seat 14, which is a cuboid shape and made of metal or plastic. It is used to store the resin liquid discharged from the collecting seat 1. The bottom of the front surface of the storage seat 14 is connected to a drain head 15, and the outside of the drain head 15 is connected to an automatic switching valve 16. The automatic switching valve 16 is an electric ball valve or a solenoid valve, which can be automatically switched on and off through the control system to facilitate the control of the discharge of the resin liquid.

[0039] Support seats 12 are fixed on both the left and right sides of the bottom of the collection seat 1. The support seats 12 are made of metal material and have a certain strength and stability. The support seats 12 are fixed to the bottom of the collection seat 1 by bolts or other connection methods to support the overall equipment and keep the equipment stable during operation.

[0040] Working principle:

[0041] The working principle of this equipment is based on the coordinated operation of the drive assembly and the winding assembly to move and unwind the winding steel strip 5, thereby removing excess resin adhesive from the surface of the fiberglass tower in one go. The specific process is as follows:

[0042] Unfolding stage: The drive motor 8 works, driving the gear plate 9 to rotate. Since the gear plate 9 meshes with the rack 11, the machine base 7 moves in a direction within the directional slide 6, thereby pulling the winding steel strip 5. At the same time, the servo motor 2 drives the winding reel 3 to rotate in the opposite direction, loosening the winding steel strip 5. Under the directional guidance of the scraper guide seat 4, the winding steel strip 5 unfolds and straightens, and is the same length as the fiberglass tower body forming mold, fitting the surface of the tower body.

[0043] Scraping stage: When the mold drives the tower body to rotate, the taut coiled steel strip 5 scrapes off the excess resin glue on the surface of the tower body in one go, ensuring the surface is flat. The scraped resin glue drips into the collection seat 1, flows along the inclined surface at the bottom of the collection seat 1 into the drain pipe 13, and then into the storage seat 14 for storage.

[0044] Rewinding stage: After scraping is completed, the drive motor 8 rotates in the reverse direction, causing the machine base 7 to move in the reverse direction. At the same time, the servo motor 2 drives the winding reel 3 to rotate in the forward direction to wind up the winding steel strip 5. During the winding process, the scraper guide seat 4 scrapes and cleans the resin glue on the surface of the winding steel strip 5.

[0045] Usage steps,

[0046] Equipment installation: Install the equipment in a suitable working position, ensuring that the collection seat 1 is located below the fiberglass tower body forming mold, and the support seat 12 firmly supports the equipment.

[0047] Parameter settings: Based on the actual dimensions of the fiberglass tower and the scraping requirements, set the speed, rotation direction, and other parameters of the servo motor 2 and drive motor 8.

[0048] Start the equipment: First start the servo motor 2 to put the winding reel 3 in a suitable initial state, then start the drive motor 8 to make the base 7 start moving and unwind the winding steel strip 5.

[0049] Scraping operation: After the coiled steel strip 5 is unwound and adheres to the surface of the tower body, the mold is started to drive the tower body to rotate, and the resin glue is scraped off.

[0050] Rewinding and cleaning: After scraping is completed, control the drive motor 8 and servo motor 2 to rotate in opposite directions to rewind the steel strip 5 and clean the resin glue on the surface of the steel strip 5.

[0051] Discharging resin: When a certain amount of resin is stored in the reservoir 14, the automatic switch valve 16 is opened to discharge the resin through the drain head 15.

[0052] This equipment can be equipped with a complete control system to achieve automated control of all components. The control system mainly includes controllers, sensors, and an operation panel.

[0053] The controller uses a programmable logic controller (PLC) or a microcontroller, which has high reliability, strong anti-interference capability, and flexible programming function. The controller receives signals from the sensors and controls the start, stop, forward and reverse rotation, and speed parameters of the servo motor 2 and drive motor 8 according to the preset program, while controlling the opening and closing of the automatic switching valve 16.

[0054] Position sensor: A position sensor is installed on the base 7 to detect the position information of the base 7 and transmit the signal to the controller. The controller controls the rotation of the drive motor 8 according to the position information to ensure that the base 7 moves accurately to the designated position.

[0055] Liquid level sensor: A liquid level sensor is installed inside the liquid reservoir 14 to detect the liquid level of the resin. When the liquid level reaches the set value, the liquid level sensor transmits a signal to the controller, which then controls the automatic switching valve 16 to open and discharge the resin.

[0056] Through the above system control expansion, this fiberglass tower resin scraping equipment can achieve automated operation, improve production efficiency and product quality, and reduce the labor intensity of operators.

[0057] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
