Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic spraying devices, specifically relating to an ultrasonic spraying device with a powerful ventilation system. Background Technology

[0002] Ultrasonic spraying equipment is a production device that uses ultrasound to atomize a solution for precision spraying. Its principle is to convert high-frequency electrical signals (typically 20kHz-3MHz) into mechanical vibrations through a piezoelectric transducer, and then transmit the vibration force to the nozzle, causing the sprayed liquid to form tiny droplets on the surface, uniformly coating the substrate and creating a uniform coating layer. Ultrasonic spraying is widely used in new energy batteries, medical devices, aerospace technology, microelectronics, and other technical fields due to its advantages such as high coating uniformity, low material waste (less than 10%), high precision in coating thickness control, wide adaptability, and low maintenance costs.

[0003] Currently, there are many descriptions of the structure of ultrasonic spraying devices. For example, patent application number "201620259328.X" describes an ultrasonic ultrafine particle spraying device, including an ultrasonic generator, an ultrasonic transducer, and an ultrasonic nozzle. The ultrasonic transducer is mounted on a bracket with an opening at the bottom and a downward mounting protrusion, featuring easy disassembly and good atomization effect. Another example is patent application number "202221442246.0," which describes an ultrasonic precision spraying device suitable for internal wall spraying, including an ultrasonic nozzle assembly, a feeding system, a three-axis walking mechanism, an automatic loading and unloading mechanism, electrical control components, a touch screen, and a device frame, featuring a compact structure, high spraying efficiency, and a high degree of automation. However, existing ultrasonic spraying devices often generate a large amount of residual waste gas during continuous spraying. If this waste gas is not treated promptly, it can lead to poor internal visibility, affecting the spraying effect, and the toxic waste gas can damage the service life of the sprayed parts. Therefore, the structure of existing ultrasonic spraying devices needs further improvement. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an ultrasonic spraying device with a powerful ventilation system. It uses a guide plate and a high-power fan at the top to quickly extract the exhaust gas generated after spraying. It has the characteristics of compact structure, adjustable exhaust volume during spraying, and high extraction efficiency after spraying. It can be widely used in the field of ultrasonic spraying device production technology.

[0015] The beneficial effects of this utility model are as follows: An ultrasonic spraying device with a powerful ventilation system features a compact structure, adjustable exhaust volume during spraying, and high extraction efficiency after spraying.

Furthermore, by installing a guide plate with a special inclined structure above the spraying equipment, the impact of wind pressure on spraying can be reduced, while effectively extracting a large amount of gas generated during spraying away from the equipment, thus purifying the working environment.

[0020] Furthermore, the sheet metal frame 1 is a fully sealed structure, made of aluminum alloy or stainless steel, and has support feet 11 at the bottom; specifically, there are 4 to 8 support feet 11, preferably 4 to 6, and shock-absorbing pads are provided inside. The ultrasonic spraying device is fixed on a flat ground by the support feet 11 with shock-absorbing pads. When the axial flow fan 3 works quickly, it can effectively eliminate vibration noise and prevent the entire device from vibrating or shifting.

[0021] Furthermore, the axial flow fan 3 is a high-power variable frequency axial flow fan with adjustable speed; specifically, the diameter of the axial flow fan 3 is 450~650mm, and the power is 1.5KW~3KW. Through the variable frequency axial flow fan 3, low-speed operation can be achieved during spraying operations to reduce the impact on spraying, and high-speed operation can be achieved after spraying to quickly and efficiently remove residual exhaust gas from the interior.

[0022] Furthermore, the guide plate 4 has an outward tilting structure from bottom to top, which facilitates the diversion of exhaust gas. The surface of the guide plate 4 is provided with a uniformly distributed porous structure, which can greatly reduce the impact of ventilation during spraying.

[0023] Furthermore, the spraying module 5, heating module 6, and liquid supply module 7 are all mounted on the support plate 12.

By adopting an integrated ventilation module design, the spraying equipment is placed inside, the circuit is uniformly designed, and the operation is simple. With the special air duct and guide plate design, the impact of exhaust during spraying can be greatly reduced. The variable frequency adjustable axial flow fan can automatically use a small air volume for exhaust during spraying and increase the air volume for exhaust after spraying. The working principle of this ultrasonic spraying device is as follows: After the workpiece to be sprayed is installed, it is placed in the designated area. The spraying trajectory and parameters are edited through the operating system of the control display screen 8, including the ultrasonic power, liquid flow rate, and airflow. At the same time, the heating program is started, the glass sliding door 2 is closed, and the heating components inside the heating module 6 start working.

After the gas in the cavity is completely extracted, the glass sliding door 2 is opened and the sprayed workpiece is taken out.
