[0022] In this embodiment: the sealing assembly 3 includes a heat sealer that can press down and stretch the bag opening to effectively eliminate bag opening wrinkles, and a transmission component that can make the heat sealer complete a preset action after contacting the pressure strip 107; The heat-sealing component includes a fixed frame 301 fixedly mounted on a placement rack 103. A support rod 302 is fixedly connected inside the fixed frame 301. Two support blocks 303 are provided between the fixed frame 301 and the support rod 302. Second uprights 304 are provided on both sides of the fixed frame 301. Second springs 305 are movably connected to the outer side of the second uprights 304.

The transmission component includes insert rods fixedly connected to both sides of the lifting frame 306. 309, the outer side of the insertion rod 309 is movably connected to a bending block 310, a third spring 311 is provided on one side of the bending block 310, a wedge block 312 is movably connected below the bending block 310, a fourth spring 313 is fixedly connected between the bending block 310 and the wedge block 312, a screw 314 is fixedly connected on the side of the two bending blocks 310 that are close to each other, and nuts 315 that are threadedly connected to the screw 314 are provided on both sides of the pressure block 307. The feeding assembly 2 also includes a connecting rod 316 fixedly connected between the support block 303 and the pressure block 307 in the same lateral position. Glue blocks 317 are provided on the upper side of the support block 303 and the lower side of the pressure block 307. The fixed frame 301 and the support rod 302 are slidably connected to the support block 303. The second spring 305 and the lifting frame 306 are slidably connected to the second upright 304. The lifting frame 306 is slidably connected to the pressure block 307. The fixed frame 301 is slidably connected to the wedge block 312. The lifting frame 306, the insertion rod 309, and the wedge block 312 are all slidably connected to the bending block 310. The insertion rod 309 is slidably connected to the third spring 311. The lifting frame 306 and the pressure block 307 are slidably connected to the screw 314. The support block 303 is connected to the connecting rod 316 by a thread. The pressure block 307 is slidably connected to the connecting rod 316. The elastic modulus of the fourth spring 313 is greater than that of the third spring 311. The fixing frame 301 provides installation positions for the support rod 302, the support block 303, and one of the heat-sealing plates 308. The support rod 302, in conjunction with the fixing frame 301, installs the support block 303. The support block 303 supports the bag opening outside the area of ​​the heat-sealing plate 308. A lifting frame 306 is installed via the second upright 304, allowing the lifting frame 306 to rise and fall along the length of the second upright 304 directly above the fixing frame 301. A second spring 305 causes the lifting frame 306, when not under external force, to tend to move away from the fixing frame 301. The lifting frame 306 provides installation positions for components such as the pressure block 307 and the insertion rod 309. Two pressure blocks 307, positioned horizontally and vertically identical to the two support blocks 303, apply pressure above the support blocks 303, close to the bag opening, under external force. Two heat-sealing plates 308, respectively located within the second upright 304 and the lifting frame 306, provide support for the bag opening. After contacting the bag opening, it is melted and bonded by heating and pressure. This is a mature existing technology in this field, so it will not be described in detail. The movable range of the bent block 310 connected to the wedge block 312 and screw 314 is limited by the insertion rod 309 and the third spring 311. The third spring 311 can make the two bent blocks 310, whose movement is not obstructed, tend to move towards each other. The movable range of the wedge block 312 in contact with the fixing frame 301 is limited by the bent block 310 and the fourth spring 313. The fourth spring 313 can make the wedge block 312, which is not subjected to external force, tend to move towards the fixing frame 301. The nut 315 limits the adjacent pressure block 307. The connecting rod 316 connects the support block 303 and the pressure block 307 so that the height between them can be changed, but the horizontal and vertical positions are always the same. The deformable rubber block 317 replaces the support block 303 and the pressure block 307 to contact the bag opening.

[0023] Working principle: When this device is installed for vacuum sealing of cooked duck meat, after placing the cooked duck meat package in the horizontal center position on the stencil plate 104 with the bag opening close to the feeding component 2, the pressure roller 206 can be raised to place the bag opening between the support roller 202 and the pressure roller 206. After that, the pressure roller 206 is not raised. Under the action of the first spring 205, the pressure roller 206 will cooperate with the support roller 202 to clamp the bag opening, thereby initially positioning the cooked duck meat package and flattening the bag opening. At this time, the operator can move the pressure roller 206 to move the clamped bag opening toward the sealing component 3. Since the part of the stencil plate 104 close to the feeding component 2 has a certain slope and the gap between the support roller 202 and the pressure roller 206 is extremely small, when the cooked duck meat package moves toward the sealing component 3, the cooked duck meat inside that is close to the bag opening will be squeezed into the bag so that the bag opening is fully exposed. After the bag opening moves between the fixed frame 301 and the lifting frame 306 due to the rotation of the pressure roller 206, the nut 315 can be adjusted according to the specifications of the cooked duck meat packaging to make the support block 303 and the pressure block 307 move horizontally on the screw 314 to a position where the projection falls on the bag opening and is close to the two sides of the bag opening. After the adjustment is completed, the cover 105 can be fastened, and then the pump 110 and the heat sealing plate 308 can be operated in sequence to extract the air in the bag and heat seal the bag opening. When the cover 105 is fastened, the pressure strip 107, which moves with it, will contact and press down on the lifting frame 306. When the lifting frame 306 moves down, the inclined wedge block 312, which is acted upon by the fixed frame 301 and the fourth spring 313, will move down along the inclined part of the fixed frame 301 and drive the bending block 310 to move horizontally against the force of the third spring 311. This causes the two bending blocks 310, which move down with the lifting frame 306 and are connected to the screw 314, to move away from each other. Based on this, the pressure block 307 will cooperate with the support block 303 to clamp and flatten the bag opening during the process of falling towards the support block 303, thereby avoiding the bag opening located between the heat-sealing plates 308 from having wrinkles that affect the sealing effect after vacuuming.

[0024] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
