As shown in fig. 4, a tooth cutter 170 having the same shape as the die is fixed to the lower end of the cutter holder 160. A pressing plate 190 is fixed under the fixed part of the tooth cutter 170 through a plurality of equal-height screws 191, and a pressing plate 200 matched with the pressing plate 190 is fixed under the pressing plate 190 through a limiting rod 201. The bottom surface of the sealing and cutting seat plate 140 is also provided with a plurality of contour sleeves 141, the sealing and welding plate 181 is connected through the contour sleeves 141, and the heating block 180 is fixed on the sealing and welding plate 181. The bottom surface of the sealing branding plate 181 is provided with a groove, and a heat insulation block 182 is fixed in the groove. The seal-iron plate 181 is coaxially disposed with the toothed cutter 170, and the cutter portion of the toothed cutter 170 is located between the seal-iron plate 181 and the pressure plate 190. The blade portion of the toothed cutter 170 is directed vertically downward and is positioned between the pressure plate 190 and the closure flap 181 and preferably engages the closure flap 181.
The film pressing plate 200 is provided with a plurality of die openings which are similar to or the same as the prefabricated box or the box product to be sealed in size, and the pressing plate 190 can be arranged the same as the film pressing plate 200, and can also be in other sizes or shapes, so long as the film pressing plate can flatten and press the cover film at the edge of the seal.
In order to ensure a burr-free sealing effect, the size of the tooth cutter 170 is preferably not larger than the size of the package, so that the size of the cover film cut by the tooth cutter 170 is slightly smaller than or equal to the size of the edge of the package, and the edge (edge sealing) of the cover film can be completely heat-sealed during subsequent film sealing.
And, the size of the heat insulation block 182 should be similar to or the same as the part inside the sealing of the packaging box, so that the sealing branding plate 181 is prevented from influencing the cover film of the part without sealing when sealing. The constant-height sleeve 141 is sleeved with a spring. The spring is used for providing resilience for the sealing and baking plate 181, and enables the cutter seat 160 to stably and uniformly descend when the sealing and cutting seat plate 140 moves downwards, and enables the sealing and baking plate 181 to keep contact with the cover film for a certain time, so that sealing is realized.

First, the film pressing plate 200 contacts the sealing lower mold frame 210, so that the prefabricated box is located in the cavity of the film pressing plate 200, and the movement of the prefabricated box in the horizontal direction is limited. As the seal carrier plate 140 continues to move downward, the platen 190, the cutter mechanism (tooth cutter 170, cutter holder 160), and the seal mechanism (seal carrier 181, insulation block 182, and heating block 180) continue to move downward. When the platen 190 contacts the platen plate 200, the cover film therebetween is sandwiched. Because of the distance between the cutter mechanism and the lower end of the pressure plate 190, the cutter mechanism and the sealing mechanism continue to move downward until the toothed cutter 170 moves downward to cut the lidding film. After the cutter holder 160 contacts the pressing plate 190, the toothed cutter 170 stops moving downwards (the toothed cutter 170 is slightly higher than the prefabricated box in the lower die frame 210 at the moment, so that the cover film can be completely cut off, and the box can be avoided being cut), the sealing and cutting seat plate 140 continues to drive the heating block 180, the cauterizing plate 181 and the heat insulation block 182 to move downwards until the cut cover film is pressed together with the prefabricated box and sealing is completed, and then the sealing and cutting seat 181, the cutter holder 160, the toothed cutter 170, the pressing plate 190 and the film pressing plate 200 are sequentially moved reversely to reset according to the sequence, wherein springs in the ejector rod 150, the equal-height sleeve 141, the equal-height screw 191 and other parts of the cutter holder 160 are in a compressed state, and the driving mechanism restores the original spacing, so that one sealing and cutting cycle is completed.
