[0003] Meanwhile, the glue-applying machines widely used in current production processes also reveal many shortcomings: complex machine structure, high maintenance costs, expensive purchase price, significant paint loss, difficulty in meeting the flexibility requirements of small-scale production, and high skill requirements for operators. Therefore, there is an urgent need to develop a small, remote-controlled roller brush system designed to improve production efficiency, reduce potential threats to human health, be more cost-effective, and flexibly adaptable to small-scale production scenarios.

Detailed Implementation

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] refer to Figure 1-5 This utility model provides a remotely controlled wet coating device, including: a feeding box 1, a storage box 2, a discharge port 3, a roller brush 4, a control device 5, a lower base plate 6, a power supply 7, an upper base plate 8, a motor 9, a roller 10, a roller brush fixing bracket 11, a cylindrical roller 12, a slip ring stator 13, a slip ring rotor 14, a temperature sensor 17, and a PTC heating element 18.

[0022] The device employs a double-layer structure, with the lower base plate 6 and upper base plate 8 securely connected by four mounting columns. The power system consists of four motors 9, each bolted to the lower base plate 6 via rollers 10. The lower base plate 6 simultaneously supports the power module 7 and the control system 5, with a dedicated mounting bracket 11 at its front end connected to the roller brush 4. The control system 5 can adjust the output and the movement speed of the motors 9 to adapt to different coating requirements and working environments, offering flexible and precise operation. It can also adjust the temperature of the roller brush 4 to ensure uniform paint adhesion.

[0023] The feeding hopper 1 is mounted on the surface of the upper base plate 8, forming a connected structure with the storage hopper 2. The bottom of the storage hopper 2 is designed with a discharge port 3, which is precisely positioned directly above the roller brush 4 to ensure accurate and continuous material delivery. Through the coordinated design of the feeding hopper 1, storage hopper 2, and discharge ports 3, automatic and uniform coating supply is achieved, reducing manual intervention and improving work efficiency. The precise cooperation between the discharge ports 3 and the roller brush 4 ensures that the coating is evenly distributed on the working surface, avoiding uneven coating or missed areas that may occur in traditional coating processes.

[0024] The operation of the device is as follows: Before starting work, the operator must load the pre-mixed and thoroughly blended paint into the supply tank 1. After starting the device, the paint in the supply tank 1 flows smoothly into the storage tank 2 under gravity through the connecting structure at its bottom. The storage tank 2 has a discharge port 3 at its bottom. These discharge ports are precisely calculated and arranged to evenly and continuously deliver the paint to the top of the roller brush 4, ensuring the uniformity of paint distribution.

[0025] The roller brush 4 makes full contact with the paint falling from the outlet 3, and spreads or coats the paint evenly on the working surface through its rotational motion. This process not only improves the utilization rate of the paint, but also ensures the uniformity and consistency of the coating.

[0026] The feed box 1 adopts a top open structure design, which supports real-time monitoring of paint balance through a visual observation window. Operators can accurately grasp the changes in the amount of paint by visual inspection or auxiliary ruler, and manually add paint.

[0027] The stator 13 of the slip ring is fixed on the bracket 11, and the rotor 14 of the slip ring is rigidly connected to the cylindrical roller 12, rotating synchronously with the roller brush 4 to ensure that the coaxiality error between the slip ring and the main shaft is <0.1mm, thus avoiding wear or vibration during rotation. A wire 16 from the fixed end of the slip ring is connected to the device power supply 7 and the control device 5, while a wire 15 from the rotating end is connected to the PTC heating element 18 and the temperature sensor 17. A protective cover is installed on the outside of the slip ring to prevent paint or dust from entering. The heating element 18 and the sensor 17 are connected via slip ring leads to prevent tangling and ensure that the roller brush 4 can rotate freely.

[0028] The temperature of the roller brush 4 can be detected at any time by the temperature sensor 17, and the heating element 18 can be heated by the control system 5 to make the coating adhere to the surface of the carbon fiber cloth.

[0029] Four motors 9 drive the rollers 10, and the speed and direction of the motors 9 can be manually adjusted by the control system 5. The rollers 10 driven by the four motors 9 provide the device with smooth movement, allowing it to move freely within the working area, suitable for small-scale painting operations. The power module 7 provides stable power support to the device, and combined with the efficient paint delivery and painting mechanism, it reduces paint waste and energy consumption, lowering operating costs.

[0030] The device mainly uses common metal plates, which are easy to purchase and inexpensive, reducing manufacturing costs. At the same time, due to the simple structural design, the processing and assembly of components require low technology, eliminating the need for complex processing equipment or high-precision technology, and making maintenance easy.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
