It is mostly used to solve the problem of difficult feeding of workpieces caused by differences in size and shape of some materials, and is an indispensable part of the flexible feeding unit.
[0003] After searching, the Chinese patent application number 202222133697.2 discloses an anti-resonance structure of a flexible vibration disk, including: a vibration disk body; two groups of fixing mechanisms, the two groups of fixing mechanisms are respectively arranged on the left and right sides of the vibration disk body, the fixing mechanism includes a driving device and a limit plate, the output end of the driving device is connected to the limit plate and is suitable for driving the limit plate to abut the side of the vibration disk body; the fixing mechanism also includes: a first mounting plate, arranged vertically, and a plurality of first mounting holes are arranged on the side of the first mounting plate; a mounting frame, a plurality of first mounting grooves are arranged vertically, and the driving device and the limit plate are both arranged on the mounting frame; a plurality of first connecting members, and the first connecting members connect the first mounting holes and the first mounting grooves.
