Description

Technical Field

[0001] This invention relates to the field of composite material molding and adhesive scraping equipment technology, and more specifically, to an adjustable adhesive scraping pressure device and method that is easy to integrate with a winding machine. Background Technology

[0002] Currently, cylindrical composite materials are formed by winding and curing. During the winding process, the fiber bundles are immersed in adhesive and then wound onto the mold. Due to the high viscosity of the adhesive, excessive adhesive adheres to the fiber bundles, requiring scraping.

[0003] In the existing technology, the method of manually applying glue by hand with a scraper following the filament-laying head is labor-intensive, results in high labor intensity for workers, and creates an unfriendly working environment for workers. At the same time, the toxic odor emitted by the glue can damage the health of workers.

[0004] In summary, at least one of the following technical problems exists:

[0005] The method of manually applying glue by hand with a scraper following the thread-laying head is labor-intensive, results in high labor intensity for workers, and creates an unfriendly working environment for workers. In addition, the toxic fumes emitted by the glue can harm the health of workers. Summary of the Invention

[0006] The main objective of this invention is to provide a device and method for adjusting the scraping pressure that is easy to integrate with a winding machine, in order to solve the problems of the existing technology of scraping glue by manually holding a scraper and following the filament laying head, which is labor-intensive, labor-intensive, and has an unfriendly working environment for workers. At the same time, the glue evaporates and emits toxic odors that can damage the health of workers.

[0007] To achieve the above objectives, according to one aspect of the present invention, an adjustable adhesive scraping pressure device is provided for easy integration with a wrapping machine, comprising:

[0008] A retainer, which is connected to the yarn-laying head of the winding machine;

[0009] A cylinder, which is connected to a cage;

[0010] A pneumatic solenoid directional valve, wherein the pneumatic solenoid directional valve is connected to a cylinder;

[0011] A pneumatic solenoid pressure regulating valve, wherein the pneumatic solenoid pressure regulating valve is connected to a pneumatic solenoid directional valve;

[0012] The scraper is connected to the cylinder.

[0013] Preferably, the cylinder has an internal threaded hole, the cage has a through hole, the internal threaded hole and the through hole are arranged opposite to each other, and the cylinder and the cage are connected by screws.

[0014] Preferably, the cage is L-shaped.

[0015] Preferably, the cylinder includes a pair of telescopic rods connected to a scraper. The scraper includes a fixed block and a scraper head. The fixed block is connected to the telescopic rods, and the scraper head is disposed on the fixed block.

[0016] Preferably, the scraper head has a wedge-shaped structure.

[0017] Preferably, the pneumatic solenoid directional valve is connected to the cylinder via a pair of air pipes. By controlling the pneumatic solenoid directional valve, the cylinder drives the scraper to retract. Then, the pneumatic solenoid pressure regulating valve is adjusted to a relatively small pressure value. After the winding machine is ready, the pneumatic solenoid directional valve is controlled to drive the cylinder to extend the scraper for scraping glue. The pneumatic solenoid pressure regulating valve is adjusted by observing the glue content on the surface of the fiber bundle. When the glue content on the surface of the fiber bundle is too high, the gas output pressure is increased to increase the scraping force; conversely, the scraping force is decreased.

[0019] Preferably, the cylinder drives the scraper to extend or retract.

[0020] Preferably, the pneumatic solenoid directional valve is used to control the cylinder to extend or retract the scraper.

[0021] According to another aspect of the present invention, a method of using an adjustable squeegee pressure device that is easy to combine with a wrapping machine is provided, comprising:

[0022] The winding machine connects to the fiber placement head via a retainer. During operation, the fiber placement head moves the adjustable scraping pressure device, ensuring it continuously scrapes the fiber bundles just wound onto the mold. A pneumatic solenoid directional valve is controlled to retract the scraper, and then the pneumatic solenoid pressure regulating valve is adjusted to a lower pressure value. Once the winding machine is ready, the pneumatic solenoid directional valve is controlled again to extend the scraper for scraping. The pneumatic solenoid pressure regulating valve is adjusted by observing the glue content on the fiber bundle surface. When the glue content is too high, the gas output pressure is increased to increase the scraping force; conversely, it is decreased to reduce the scraping force.

[0023] The technical solution of this invention has the following technical effects:

[0024] An adjustable scraping pressure device is installed on the fiber placement head of the winding machine. Its connection is via a retainer, allowing the placement head to move the device, ensuring continuous scraping of the fiber bundles just wound onto the die. An industrial compressed air source is connected to the device. A pneumatic solenoid directional valve is controlled to retract the scraper, and a pneumatic solenoid pressure regulating valve is adjusted to a low pressure value. Once the winding machine is ready, the valve is controlled again to extend the scraper. The pressure is adjusted by monitoring the glue content on the fiber bundle surface. High glue content increases the scraping force, while low content decreases it. This system features simple structure, ease of use, wide adaptability, high flexibility, simple manufacturing, and low cost. Attached Figure Description

After the winding machine is ready, the pneumatic electromagnetic reversing valve 2 is controlled to make the cylinder 4 drive the scraper 5 to extend for scraping glue. The pneumatic electromagnetic pressure regulating valve is adjusted by observing the glue content on the surface of the fiber bundle. When the glue content on the surface of the fiber bundle is too high, the gas output pressure is increased to increase the scraping force, and vice versa.

During operation, the filament laying head of the winding machine drives the adjustable scraping pressure device to move, so that it always scrapes the fiber bundle that has just been wound onto the mold.

By controlling the pneumatic solenoid reversing valve 2, the cylinder 4 drives the scraper 5 to retract. Then, the pneumatic solenoid pressure regulating valve is adjusted to a small pressure value. After the winding machine is ready, the pneumatic solenoid reversing valve 2 is controlled to make the cylinder 4 drive the scraper 5 to extend for scraping. The pneumatic solenoid pressure regulating valve 1 is adjusted by observing the glue content on the surface of the fiber bundle. When the glue content on the surface of the fiber bundle is too high, the gas output pressure is increased to increase the scraping force; conversely, the scraping force is decreased.

During operation, the fiber placement head moves the adjustable scraping pressure device, ensuring it continuously scrapes the fiber bundles just wound onto the mold.
