Feeding mechanism for sound-absorbing cotton with different thicknesses

The utility model relates to a feeding mechanism for sound-absorbing cotton with different thicknesses, which comprises a needling mechanism, a lifting assembly and a shifting assembly, the needling mechanism comprises a supporting seat and needling assemblys.According to the feeding mechanism for the sound-absorbing cotton, the needling assemblies are continuously positioned and installed through the supporting seat, and the needling assemblies at the two ends form a group for cooperative operation; the output module drives the connecting block to displace, so that the material puncturing rod downwards punctures along the puncturing hole in the supporting seat in a staggered mode to puncture the sound-absorbing cotton, the lifting assembly and the moving assembly are used for processing, feeding is conducted in a puncturing mode, feeding force application between the material and the material is stable, the material can be effectively prevented from falling off, and the quality of the sound-absorbing cotton
