Filter sealing device and application method thereof

The invention discloses a filter sealing device and an application method thereof. The filter sealing device comprises a motor, a main shaft, a workpiece pressing block, a workpiece tray, a cam, a pedal and the like. The invention is suitable for edge trimming sealing of cylindrical parts. The application method comprises the following steps: installing a filter element on the shell of a filter, putting the filter on the workpiece tray, stepping the pedal so that the workpiece pressing block abuts against the filter element, starting the motor so as to drive the filter to rotate, pulling a right draw rod to roll the edge of the filter, pulling a left draw rod to trim the edge of the filter, releasing the pedal after finishing processing, and taking off the processed filter. The filter sealing device can simultaneously carry out edge rolling and edge trimming on the workpiece, thereby having high working efficiency; the positions of an edge rolling wheel and an edge trimming wheel can be adjusted, thus, the fi
