[0004] Chinese Patent Application No. 202021033528.6 discloses a pressing mechanism comprising a base, a first feeding mechanism for conveying a sealing gasket, a second feeding mechanism for conveying a cover shell, and a pressing mechanism. The first feeding mechanism automatically feeds the sealing gasket and places it on top of the cover shell. The pressing mechanism presses the sealing gasket and the cover shell together. The second feeding mechanism automatically feeds the cover shell and conveys the pressed sealing gasket and cover shell away. The entire process of assembling the mechanical seal cover is mechanized, eliminating the need for manual feeding of the sealing cover and cover shell, thereby improving the processing efficiency of the pressing equipment for processing mechanical seal components.
