Description

Technical Field

[0001] The utility model relates to the technical field of bouncing screens, in particular to a supporting structure of a bouncing screen with adjustable angle. Background Art

[0002] A bouncing screen is a device used for screening particulate materials, commonly used in industrial production, laboratory research, and materials analysis. The bouncing screen achieves screening by causing the material to bounce on the sieve holes. Under the influence of vibration, the material will bounce on the sieve holes. Depending on the size and shape of the material, as well as the size of the sieve holes, materials of different particle sizes will pass through the sieve holes or be screened out. The bouncing screen is primarily composed of a vibrating mechanism, a screen frame, and a screen mesh. The vibrating mechanism generates vibration, causing the material to bounce on the sieve holes; the screen frame is the component that holds the screen mesh, typically made of metal or plastic; the screen mesh is the component used to screen the material, and its aperture determines the particle size of the material. As an efficient and precise particulate material screening device, the bouncing screen plays an important role in industrial production and scientific research, providing reliable technical support for the processing and utilization of particulate materials. During use, the angle of the bouncing screen needs to be adjusted.
