[0030] Working principle of the above embodiment: in the packaging machine assembly, the swing arm 1 is connected with a driving device, and the air suction flow channel 11 is connected with a negative pressure device. When the suction block contacts the inner frame paper through the elastic gasket, the inner frame paper will be adsorbed by the negative pressure generated by the suction hole and the butt joint hole. Then the swing arm drives the suction block to move, and the inner frame paper is transferred to a specific work station to realize the conveying of the inner frame paper. Compared with the prior art, the elastic gasket made of flexible material contacts and adsorbs the inner frame paper, which plays a role in buffering contact, can reduce the probability of damage to the inner frame paper, and the elastic gasket can form a better airtight connection structure with the inner frame paper through slight deformation during the adsorption process, improve the adsorption stability, avoid the inner frame paper from deviating or falling off during the transfer process, in addition, the elastic gasket and the mounting base are detachably connected, only new elastic gaskets need to be replaced during later maintenance, without the need to replace the whole suction block, which greatly reduces the maintenance cost.
