Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker cover cleaning, in particular to a loudspeaker cover cleaning machine. Background Art

[0002] The speaker cover usually refers to the covering located on the outside of the speaker. Its main function is to protect the internal components of the speaker from damage by the external environment. Since the speaker cover is often exposed to the external environment, it is easy to accumulate dust, dirt and bacteria. These attachments will hinder the transmission of sound, affect the sound quality, and make the sound unclear. Therefore, the speaker cover needs to be cleaned.

[0003] The existing speaker cover cleaning device is mainly composed of a frame, a conveying mechanism and a cleaning mechanism. When cleaning the speaker cover, the cover is first placed on the conveying mechanism. The conveying mechanism is used to convey the speaker cover from the entrance of the device to the working area of ​​the cleaning mechanism. When the speaker cover reaches the working area of ​​the cleaning mechanism, the cleaning mechanism starts to work. Through the high-speed rotation of the rotating brush and the cooperation of the spray assembly, dust, dirt and other impurities on the surface of the cover can be removed.

[0004] During the dust removal and cleaning process, since the dust on the speaker cover needs to be cleaned, the cleaning can be achieved by the cooperation of an air gun or a water gun. During the cleaning process, the cleaned dust gas is easy to spread and pollute the working air environment. Secondly, during flushing, due to the lack of coordination between the flushing advancement process and the flushing gun head, cleaning dead corners are easily generated, resulting in incomplete cleaning. Therefore, a speaker cover cleaning machine is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a speaker cover cleaning machine.
