Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning equipment, in particular to a mechanical equipment for cleaning and drying materials. Background Art

[0002] Ultrasonic cleaning machine is a new equipment that uses ultrasonic cleaning technology to clean the surface of industrial parts and other materials. It gradually replaces traditional manual cleaning, rinsing and organic solvent immersion in factory production and becomes a green and environmentally friendly product cleaning method. Ultrasonic cleaning machine mainly converts the sound energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and radiates the ultrasonic wave into the cleaning liquid through the cleaning tank wall. Due to the radiation of ultrasonic waves, the microbubbles in the liquid in the tank can maintain vibration under the action of sound waves. The huge pressure generated by ultrasonic cavitation is used to destroy the adsorption of dirt and the surface of the cleaning parts, which can destroy dirt, remove or weaken the boundary dirt layer, increase stirring and diffusion, and use ultrasonic cleaning machines to reduce the amount of chemical solvents, thereby greatly reducing environmental pollution.

[0003] For example, the cleanliness and dryness of permanent magnetic tiles have a great impact on the assembly and adaptation performance. The industry cleaning of permanent magnetic tiles is mainly reflected in incomplete cleaning. There is a large amount of magnetic powder on the surface of the product. Although the cleaning speed is slowed down and the cleaning requirements can be met, the user's output and efficiency are greatly reduced, resulting in a great contradiction between cleaning and output, which has become an important factor leading to the slow development of permanent magnetic equipment. On the other hand: the product has a relatively high demand for dryness. If the requirements for direct packaging can be met after cleaning, the production efficiency will be further improved.

[0004] For example, the Chinese patent document with publication number CN106391561A discloses an ultrasonic cleaning and drying line for permanent ferrite magnetic tiles, including a frame, an ultrasonic pre-cleaning tank and a discharging platform are provided at both ends of the frame, a cleaning device, a blow-drying device, and a drying device are sequentially installed on the frame from the ultrasonic pre-cleaning tank to the discharging platform, and a transmission group controlled by a transmission motor for material transmission is provided between the ultrasonic pre-cleaning tank, the cleaning device, the blow-drying device, the drying device, and the discharging platform. Its mechanical structure is relatively complex, the cleaning process is not optimized enough, and there is still a lot of room for improvement.

[0005] Therefore, how to provide a mechanical device for cleaning and drying materials so that the materials can achieve a fully automatic cleaning, water cutting, drying and cooling process, thereby improving the cleaning effect and cleaning efficiency of the materials, is a technical problem that needs to be solved.
