[0024] Specifically, the sprocket 15 can be driven to rotate by starting the servo motor 14. As the sprocket 15 rotates, the outer chain 16 can be driven to move. At the same time, the moving block 17 above it will pull the L-shaped plate 4 to move to the right together. As the L-shaped plate 4 moves, the cylinder 5 and the plastic film 6 can be driven to move to the right. When the plastic film 6 moves to the right, it will initially drive the excess film to move to the right. When it reaches the position of the meat food, the plastic film 6 cannot continue to move to the right due to its obstruction. However, as the L-shaped plate 4 continues to move, the plastic film 6 rotates on the cylinder 5 and pulls out a new film, thereby wrapping the meat food. When the front L-shaped plate 4 moves to the gear 9, the rack 7 below it will mesh with the gear 9 to make it rotate. As the gear 9 rotates, the rack plate 10 moves to the left.

By starting the hot plate 203, the films on both sides are melted and bonded together during the film extrusion process with the film above the operating table 3. The first electric telescopic rod is started to move a short distance toward the top. At this time, the second electric telescopic rod 204 is started to drive the sealing plate 205 to move toward the bottom to perform hot-melt sealing on the right side. At the same time, due to the recovery characteristics of the sealing plate 205, the bent parts on both sides will stretch, thereby sealing the film to prevent gaps from being generated. At the same time, the cutting knife 206 will also move with it to cut the film. After completion, the first electric telescopic rod 201 and the second electric telescopic rod 204 are started to move toward the top together.

At the same time, the moving block 17 above it will pull the L-shaped plate 4 to move to the right together. As the L-shaped plate 4 moves, the cylinder 5 and the plastic film 6 can be driven to move to the right. When the plastic film 6 moves to the right, it will initially drive the excess film to move to the right. When it reaches the position of the meat food, the plastic film 6 cannot continue to move to the right due to its obstruction. However, due to the continued movement of the L-shaped plate 4, the plastic film 6 rotates on the cylinder 5 and pulls out a new film, thereby wrapping the meat food. When the front L-shaped plate 4 moves to the gear 9, the rack 7 below it will engage with the gear 9 to make it rotate. As the gear 9 moves, the plastic film 6 will move to the right side. The rack plate 10 is rotated to move to the left, and with the movement of the rack plate 10, the air pipe 11 is driven to move together, so that the air pipe 11 is in the middle of the two layers of film. By starting the vacuum machine 13, the air between the two layers of film can be sucked out, so that the film and the meat food are closely attached together, thereby completing the vacuum packaging of the meat food, and through the heat sealing mechanism, by starting the first electric telescopic rod 201, the bracket 202 and the mechanism above it can be driven to move to the bottom together, and by starting the hot blanching plate 203, in the process of squeezing the film above the operating table 3, the films on both sides are melted and bonded together, and the first electric telescopic rod is started to move a short distance to the top. At this time, the second electric telescopic rod 204 is started, which can drive the sealing plate 205 to move to the bottom, and the right side is hot-melt sealed. At the same time, due to the recovery characteristics of the sealing plate 205, the bent parts on both sides will stretch, thereby sealing the film to prevent gaps from being generated, and at the same time the cutting knife 206 The film will also be cut as it moves. After completion, the first electric telescopic rod 201 and the second electric telescopic rod 204 are started to move toward the top together, so that the vacuum package can be sealed.
