Audio equipment is mainly composed of audio equipment, sound source equipment, signal amplification equipment, sound restoration equipment and various assembly accessories. It can be as large as meeting the sound reinforcement needs of concerts with tens of thousands of people, or as small as meeting the needs of playing musical instruments and singing in individuals and families. The audio silencer bag is one of the important parts of the audio, and it is necessary to punch holes in the audio silencer bag during the processing of the audio silencer bag.

[0003] For example, the authorization announcement number CN 211304855 U discloses a processing mechanism for a silencer package cover plate, which includes a punching device and a positioning device that cooperate with each other. The punching device includes a drill shaft, and the positioning device includes a workbench and a positioning seat. The positioning seat is provided with a placement groove, and the placement groove passes through the positioning seat in the horizontal direction. Two clamping plates connected to the positioning seat are provided in the placement groove, and the two clamping plates are respectively placed on the two side walls of the placement groove. The two clamping plates and the placement groove constitute a placement station. The positioning seat is provided with a working chamber connected to the placement station, and the working chamber is provided with a cylinder, a preload and a positioning head connected in sequence. The cylinder drives the positioning head to extend into the placement station, and the positioning head is provided with a positioning hole corresponding to the drill shaft.

[0004] In the above, when the drill shaft drills the silencer bag, a lot of dust and debris will be generated, and these dust and debris will float everywhere or fall onto the surface of the silencer bag, making it difficult to clean the dust and debris, and finally resulting in low work efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a muffler bag punching device which can clean dust and debris generated during punching and collect debris to improve work efficiency.
