The push plate driving mechanism 15 can be selected as an air cylinder, a piston rod of the air cylinder can stretch and retract to drive the push plate 14 to reciprocate, and in order to obtain large pressure, a plurality of air cylinders are adopted for combined output, so that when the product specification is converted, a plurality of air cylinders are arranged at intervals in the length direction of the push plate 14 through different combinations of the air cylinders, and different lateral pressures and different pressure positions can be obtained.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
