Example two: the lifting device 14 is arranged on the translation device 11 and comprises a base 44, a driving cylinder 45 fixed on the base 44 and a driving block 46 connected with a stroke rod of the driving cylinder 45, two ends of the driving block 46 are respectively provided with a driving shaft 47, the driving shaft 47 is hinged with a first end of a left upper rocker arm 48 and a first end of a left lower rocker arm 49, a second end of the left upper rocker arm 48 and a second end of the left lower rocker arm 49 are respectively hinged on the lower molding die 13 or the buffer damping device 25 and the base 4, the base 4 is also hinged with a second end of a right lower rocker arm 50, a first end of the right lower rocker arm 50 is hinged with a first end of a right upper rocker arm 51, a second end of the right upper rocker arm 51 is hinged on the lower molding die 13 or the buffer damping device 25, and first ends of the left upper rocker arm 48 and the right upper rocker arm 51 are hinged with a pull rod 52; the left upper rocker arm 48 is parallel to the right upper rocker arm 51, and the left lower rocker arm 49 is parallel to the right lower rocker arm 50; when the driving cylinder 36 pushes the driving shaft 47 to move forward and backward, the driving shaft 47 causes the angle between the left upper rocker arm 48 and the left lower rocker arm 49 and the angle between the right upper rocker arm 51 and the right lower rocker arm 50 to change, so that the height of the lower suction mold 13 or the cushion damper 25 from the base 4 is variable. When the lifting mechanism works, the tail end of the driving cylinder 36 is hinged to the rack 1, the driving block 37 is pushed to move, the driving block 37 is hinged to the first ends of the upper left rocker arm 48 and the lower left rocker arm 49, and therefore the upper left rocker arm 48 and the lower left rocker arm 49 are pushed to move, and due to the fact that the upper left rocker arm 48, the lower left rocker arm 49, the upper right rocker arm 51 and the lower right rocker arm 50 are of hinged linkage type structures, the upper left rocker arm 48, the lower left rocker arm 49, the upper right rocker arm 51 and the lower right rocker arm 50 deflect integrally and correspondingly, and therefore change in height is achieved.

The plastic film 8 with the paper film 10 in a heat sealing manner continuously moves along with the plastic film conveyor 2 and reaches the position of the row cutting mechanism 6, the row cutting mechanism 6 comprises a transverse cutting device 53 and a longitudinal cutting device 54, the transverse cutting device 53 comprises a frame body 55, a lifting cylinder (not shown in the figure) arranged on the frame body 55, a plurality of groups of transverse cutters 57 which can lift up and down through the lifting cylinder (not shown in the figure) and transverse pressing plates 58 which are correspondingly matched with the transverse cutters 57, and the transverse pressing plates 58 can move transversely through transverse cylinders 59, so that the plastic film 8 between the transverse cutters 57 and the transverse pressing plates 58 can be cut transversely; the slitting device 54 comprises an extrusion roller 60 and a plurality of longitudinal roller cutters 61, the plastic film 8 is arranged between the extrusion roller 60 and the longitudinal roller cutters 61, and the extrusion roller 60 extrudes the plastic film 8 and contacts the longitudinal roller cutters 61, so that the longitudinal roller cutters 61 cut the plastic film longitudinally.

Specifically, the plastic film 8 firstly reaches the position of the transverse cutting device 53, a lifting cylinder (not shown in the figure) of the transverse cutting device 53 works to drive the transverse cutter 57 to move upwards, and the plastic film 8 with the paper film 10 in a heat sealing mode is extruded between the cutting edge of the transverse cutter 57 and the transverse pressing plate 58, and then the transverse cylinder 59 drives the transverse pressing plate 58 to move transversely, so that the plastic film 8 with the paper film 10 in a heat sealing mode is pressed against the cutting edge of the transverse cutter 57, and the plastic film 8 with the paper film 10 in a heat sealing mode is cut off in the transverse direction; then, the transversely cut plastic film 8 reaches the position of the longitudinal cutting device 54 and passes through between the extrusion roller 60 and the longitudinal hob 61, naturally, under the combined action of the extrusion roller 60 and the longitudinal hob 61, the longitudinal hob 61 cuts the plastic film 8 with the paper film 10 in a longitudinal heat sealing mode, and the cut packaged product directly falls into the discharging mechanism 7 and reaches a designated position along with the discharging mechanism 7.

The discharging mechanism 7 is a conveyor, such as: a belt conveyor.

The plastic suction mechanism 3 and the heat sealing mechanism 5 of the invention need to be adjusted in the conveying direction of the plastic film conveyor 2 during debugging, and a translation device 11 is specially designed to realize the function, specifically, the translation device 11 comprises an underframe 56, a guide rail 63 arranged on the underframe 56 and a slide block 64 matched with the guide rail 63, a driving shaft 65 is arranged on the rack 1, a driving bevel gear 66 is arranged on the driving shaft 65, a driven shaft 67 is arranged on the underframe 56, a driven bevel gear 68 meshed with the driving bevel gear 66 is arranged on the driven shaft 67, the driven shaft 67 is provided with an external thread, the external thread is in threaded connection with a nut block 69, the driven shaft 67 is driven to rotate by rotating the driving shaft 65, and then the nut block 69 moves axially relative to the driven shaft 67. The base 4(35) of the lifting device 14 of the plastic sucking mechanism 3 or the heat sealing mechanism 5 is fixedly connected with the nut block 69, and the base 35 is fixedly connected with the sliding block 64, so that when the nut block 69 moves relative to the driven shaft 67, the lifting device 14 is synchronously driven to move, and then the plastic sucking mechanism 3 and the heat sealing mechanism 5 move.
