一种研磨工作台的吸音罩
By designing a sound-absorbing cover with a support frame and noise reduction components, noise is absorbed using sound-absorbing cotton boards and sealing strips. By adjusting the angle of the sound-absorbing cover, the problem of poor noise reduction effect in existing technologies with noise envelopment is solved, achieving better noise control.

AI Technical Summary
Existing technologies cannot effectively achieve enveloping noise reduction during the grinding process, resulting in poor noise reduction performance.
A sound-absorbing cover including a support frame and a noise reduction component was designed. The noise reduction component consists of a sound-absorbing cover, a sound-absorbing cotton board, and a sealing strip. It absorbs noise through a sound-absorbing cavity structure, and the angle of the sound-absorbing cover is adjusted by rotating a screw to better cover the workpiece grinding area.
It effectively reduces noise and ensures that the soundproof cover can better cover the grinding area of the workpiece, thus improving the noise reduction effect.
