an angle inserting sliding cam is fixed on the part, located on the left side of the left vertical plate, of the left lower second rotating shaft, and is used for synchronously rotating along with the left lower second cam when the left lower first cam drives the left lower second cam to rotate through a connecting arm; the left vertical plate is further provided with a guide rail, the insertion angle is assembled in the guide rail in a guiding mode, a sliding groove is formed in the angle insertion sliding cam, the insertion angle is provided with an insertion portion inserted into the sliding groove, and the insertion angle is used for extending out and retracting along the guide rail in a reciprocating mode in the circulating rotation process of the angle insertion sliding cam.
8. The cross sealing mechanism with four connecting rods as claimed in any one of claims 5 to 7, wherein: a first pinion is fixed on the part, located on the right side of the right vertical plate, of an output shaft of the driving motor, a second pinion meshed with the first pinion, a third pinion meshed with the second pinion, a fourth pinion meshed with the third pinion and a fifth pinion meshed with the fourth pinion are sequentially and rotatably assembled on the right vertical plate from bottom to top, and the fifth pinion and one cam in an upper connecting rod structure on the right vertical plate share a rotating shaft rotatably assembled on the right vertical plate so as to realize linkage; the second auxiliary gear and a cam in the lower connecting rod structure on the right vertical plate share a rotating shaft which is rotatably assembled on the right vertical plate; the third and fourth pinions serve as transfer pinions for reversing the direction of rotation of the fifth and second pinions.
9. The cross-sealing mechanism with four-bar linkage as claimed in claim 8, wherein: a cam which shares one rotating shaft with the fifth pinion on the right vertical plate is defined as an upper right first cam, the rotating shaft which penetrates through the fifth pinion is defined as an upper right first rotating shaft, the cam which is connected with the upper right first cam through a connecting arm is defined as an upper right second cam, and the rotating shaft which penetrates through the upper right second cam is defined as an upper right second rotating shaft;
the upper right first rotating shaft is fixed with a first belt pulley, the upper right second rotating shaft is fixed with a second belt pulley, and the first belt pulley and the second belt pulley are in belt transmission so that the upper right first cam and the upper right second cam synchronously move.
10. The cross-sealing mechanism with four-bar linkage as claimed in claim 9, wherein: a cam which shares one rotating shaft with the second auxiliary gear on the right vertical plate is defined as a right lower first cam, the rotating shaft which penetrates through the second auxiliary gear is defined as a right lower first rotating shaft, the cam which is connected with the right lower first cam through a connecting arm is defined as a right lower second cam, and the rotating shaft which penetrates through the right lower second cam is defined as a right lower second rotating shaft;
and a third auxiliary belt pulley is fixed on the lower right first rotating shaft, a fourth auxiliary belt pulley is fixed on the lower right second rotating shaft, and the third auxiliary belt pulley and the fourth auxiliary belt pulley are in belt transmission so as to enable the lower right first cam and the lower right second cam to synchronously act.
