This utility model discloses a filter paperboard punching mechanism, relating to the field of filter paperboard processing technology. It includes a hydraulic punching main unit, with a punching worktable on the front side of the main unit. A lower punching die is fixedly connected to the upper front end of the worktable. A hydraulic telescopic rod is fixedly connected to the upper end of the main unit via a cantilever, positioned directly above the lower punching die. Through the use of elastic heating support pads and elastic pressure pads, the loose fiber structure of the filter paperboard is effectively prevented from being compacted, ensuring the air permeability and filtration efficiency of the filter paperboard. Simultaneously, the elastic heating support pads heat the filter paperboard when in contact with it, softening the fibers and preventing brittle breakage, thus improving the quality of the punching process. Furthermore, the elastic pressure pads further reduce the direct impact of the punching blade on the paperboard, resulting in a smoother punching edge, reducing burrs and fiber damage, and improving the overall quality of the product.

This invention proposes a high-frequency ultrasonic cutting tool that facilitates piercing and cutting. An auxiliary positioning mechanism is detachably connected to the outer wall of the first housing to assist in adjusting the cutting edge of the blade. This mechanism also connects to the external cutting machine mounting port, improving adjustment and installation efficiency. A limiting chamber and parallel-side mounting of the ultrasonic transducer assembly ensure stable assembly and reduce the failure rate. The flat-sword shaped blade facilitates cutting, and a drag-reducing surface lowers resistance, significantly reducing the risk of blade breakage. A pre-compression component pre-presses the material to facilitate cutting, improving the yield rate. A flexible ring assists in stress relief and prevents damage to the first and second housings when they are compressed, while also preventing overload during threaded connections, allowing for position adjustment, and extending service life.
