Pressing mechanism of vacuum filling machine

The pressing mechanism of the vacuum filling machine comprises a first fixing plate, the upper surface of the first fixing plate is in threaded connection with a first fixing piece, the front surface of the first fixing piece is fixedly connected with a pressing air cylinder, and a piston rod is arranged on the front surface of the pressing air cylinder. And the front surface of the piston rod is fixedly connected with a second fixing piece. By means of the structure, in order to guarantee the flatness and thickness tolerance of the surface of the whole bag and control the whole precision and the machining cost, the fixing plates of the structure are connected through the reinforcing ribs and connected with the vacuumized box body to form a whole, the plane making contact with a product is machined again after the fixing plates are combined together, and the whole machining precision can be controlled very high; the overall strength is high, the stability is lasting, and in the pressing process, due to the fa
