[0025] like Figures 1 to 4 As shown, a hot-melt flattening device for food packaging is used to perform hot-melt flattening processing on some food packaging bags or boxes, such as frozen foods (dumplings, ice cream), biscuit boxes, Tetra Pak packaging, etc. Structurally, the hot-melt flattening device includes a hot-melt frame 1, with a hot-melt operating platform 2 connected to the bottom of the frame 1. A hot-melt fixture positioning mechanism is installed on the operating platform 2, and a hot-melt fixture 3 is installed on the positioning mechanism. The food packaging bag or box to be hot-melted is placed on the hot-melt fixture 3, and the position of the fixture 3 is adjusted by the positioning mechanism. Simultaneously, a hot-melt heating and pressing plate 4 is movably arranged above the fixture 3. The top of the plate 4 is connected to the bottom surface of a movable pressure plate 5, and a lifting mechanism is installed on the movable pressure plate 5 to move it up and down towards the hot-melt fixture 3. When it is necessary to perform hot-melt flattening on food packaging bags or boxes in the hot-melt jig 3, the hot-melt heating platen 4 (an existing heating plate structure that achieves heating by electricity; and can be designed into different heating plate shapes according to requirements) is heated. When the hot-melt heating platen 4 reaches the designed required temperature, the lifting mechanism is controlled to drive the hot-melt heating platen 4, which is installed and connected to the bottom of the movable platen 5, to move towards the hot-melt jig 3. The hot-melt heating platen 4 performs hot-melt flattening and sealing on the food packaging bags or boxes in the hot-melt jig 3, thereby shaping the food packaging bags or boxes into the designed shape, while also performing hot-melt flattening and sealing.

[0026] Furthermore, the hot-melt tooling positioning mechanism includes a hot-melt tooling base 21. The bottom end of the hot-melt tooling base 21 is bolted to the hot-melt operating platform 1, and the top end of the hot-melt tooling base 21 is connected to a telescopic cylinder 22. The conveying end rod of the telescopic cylinder 22 is connected to the hot-melt tooling support plate 22, and the top end of the hot-melt tooling support plate 22 is rotatably connected to the hot-melt tooling 2. Simultaneously, a rotary cylinder is provided at the bottom end of the hot-melt tooling support plate 22. The cylinder body of the rotary cylinder is bolted to the bottom end of the hot-melt tooling support plate 22, and the output end rod of the rotary cylinder rotatably passes through the hot-melt tooling support plate 22 and connects to a rotating platform. The rotating platform is positioned between the hot-melt tooling support plate 22 and the hot-melt tooling 2. The bottom end of the rotating platform is used for rotational limiting of the top surface of the hot-melt tooling support plate 22, and the top end of the rotating platform is bolted to the hot-melt tooling 21. According to the requirements, select a suitable hot melt jig 2 and install the hot melt jig 2 on the rotating round table; then place the food packaging bag or box that needs to be hot melt flattened into the corresponding hot melt jig 2; adjust and control the position of the hot melt jig 2 by adjusting the telescopic cylinder 22 and the rotary cylinder so that the hot melt heating and pressing plate 4 above can perform hot melt flattening processing on the food packaging bag or box in the hot melt jig 2.

[0027] Furthermore, the lifting mechanism of this setup includes a lifting cylinder 51; the conveying end rod of the lifting cylinder 51 is used to connect with the movable pressure plate 5, and the cylinder shell of the lifting cylinder 51 is used to connect with the top plate 11, which is installed on the top of the hot melt machine frame 1; the movable pressure plate 5 and the hot melt jig support plate 22 are movably arranged relative to each other, so as to facilitate the adjustment of the positions of the movable pressure plate 5 and the hot melt jig support plate 22 respectively.

[0028] Meanwhile, movable support guide rods 52 are respectively provided around the movable pressure plate 5; the top ends of the movable support guide rods 52 movably pass through the movable pressure plate 5 and are used to connect and fix to the top plate 11, and the bottom ends of the movable support guide rods 52 movably pass through the hot melt jig support plate 22 and are used to connect and fix to the hot melt operation platform 1. The movable support guide rods 52 serve as "movable guide structures" between the movable pressure plate 5 and the hot melt jig support plate 22. When the movable pressure plate 5 and the hot melt jig support plate 22 are controlled to move relative to each other, they can "stablely move" along the movable support guide rods 52 respectively.

[0029] Furthermore, in this embodiment, elastic limiting members are respectively provided on both sides of the hot melt jig support plate 22; the elastic limiting member includes a movable limiting shaft 23, one end of which movably passes through the hot melt jig support plate 22 and is connected to an end cap for preventing the hot melt jig support plate 22 from sliding out of the top of the movable limiting shaft 23, and the other end of which is used to connect and fix to the hot melt operation platform 1; a protective spring 24 is sleeved on the end of the movable limiting shaft 23 near the hot melt operation platform 1, the protective spring 24 is disposed between the hot melt jig support plate 22 and the hot melt operation platform 1, one end of the protective spring 24 is used to connect to the hot melt jig support plate 22, and the other end of the protective spring 24 is used to connect to the hot melt operation platform 1. In this way, when adjusting and controlling the movement of the hot melt jig support plate 22, and when the "hot melt heating and pressing plate 4" is in the heating state and is used to heat melt and flatten the food packaging bag or packaging box in the hot melt jig 3, the elastic limiting member can play a certain elastic protection role.
