[0026] Furthermore, the blanking component 6 can blank the packaging bags after sealing, thereby further accelerating the sealing efficiency of the packaging bags.

[0027] In one embodiment of the present invention, Figure 2 As shown, the hot pressing assembly 3 may include two electric push rods 30, a hot pressing mold 31 and a supporting mold 32, wherein the two electric push rods 30 are symmetrically arranged on the upper surface of the support plate 2, the support plate 2 is provided with a first slide groove 20, the hot pressing mold 31 is arranged at the output end of the electric push rod 30, and the hot pressing mold 31 is slidably connected to the first slide groove 20, the supporting mold 32 is arranged on the upper surface of the base plate 1, and the supporting mold 32 is located directly below the hot pressing mold 31.

It can be understood that the utility model is also provided with a temperature control device (not shown in the figure), and the temperature of the hot pressing mold 31 can be kept constant by the temperature control device.

[0029] Furthermore, if Figure 1 As shown, the transmission assembly 4 may include a first tooth plate 40, a gear 41 and a second tooth plate 42, wherein the first tooth plate 40 is arranged on the side wall of the hot pressing mold 31, the gear 41 is rotatably arranged on the side wall of the support plate 2, and the gear 41 is meshingly connected with the first tooth plate 40, the side wall of the support plate 2 is provided with a second slide groove 21, a slider 10 is slidably provided in the second slide groove 21, the second tooth plate 42 is connected to the slider 10, and the second tooth plate 42 is meshingly connected with the gear 41.

[0031] In the embodiment of the utility model, when the hot pressing mold 31 drives the first tooth plate 40 to move downward, the second tooth plate 42 can be driven to move upward with the cooperation of the gear 41 and the second tooth plate 42, that is, the movement directions of the first tooth plate 40 and the second tooth plate 42 are opposite.

[0032] In one embodiment of the present invention, Figure 3As shown, the cylinder assembly 5 may include a cylinder body 50, a piston 51 and a piston rod 52, wherein the cylinder body 50 is arranged on the upper surface of the base plate 1, and the conduit 9 is connected to the cylinder body 50, the piston 51 is slidably arranged inside the cylinder body 50, and the two ends of the piston rod 52 are respectively connected to the second gear plate 42 and the piston 51.

[0033] In an embodiment of the utility model, when the piston rod 52 pushes the piston 51 to move downward, air can be blown into the trachea 11 through the conduit 9, and the packaging bag will not be adsorbed at this time. When the piston rod 52 pushes the piston 51 to move upward, air can be sucked into the trachea 11 through the conduit 9 to adsorb the packaging bag, so that the packaging bag fits tightly against the support block 7, thereby preventing the packaging bag from being offset.

[0034] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the blanking assembly 6 may include a rotating shaft 60 and two blanking plates 61 , wherein the rotating shaft 60 is rotatably disposed on the support plate 2 , a shaft sleeve 62 is sleeved on the rotating shaft 60 , and the two blanking plates 61 are symmetrically disposed on the shaft sleeve 62 .

[0038] Similarly, when the electric push rod 30 drives the hot pressing mold 31 to move upward, with the cooperation of the gear 41 and the second gear plate 42, it drives the piston rod 52 and the piston 51 to move downward, and sucks and blows the packaging bag through the conduit 9 and the air pipe 11, that is, the packaging bag is released. At this time, it is driven by the driving shaft 60 and drives the unloading plate 61 to rotate 180 degrees to scrape the packaging bag after edge sealing into the collection tank, completing the unloading process of the packaging bag.
