[0020] Reference Figures 1 to 9 The utility model is further described in detail.

[0021] A sealing packaging machine for bayberry packaging boxes, comprising a frame 1, a workbench is provided on the frame 1, a lower mold assembly 2 that can slide forward and backward is provided on the workbench, an upper mold assembly 3 that can be lifted and lowered is provided above the sealing template assembly, a laminating assembly 4 is also provided between the upper mold assembly 3 and the lower mold assembly 2, the upper mold assembly 3 comprises a driving frame 30, an upper mold frame 31 that can be detachably matched with the driving frame 30, an ironing plate assembly 32 located on the upper mold frame 31, and an annular cutter 33 arranged outside the ironing plate assembly 32, the driving frame 30 is provided with There is an assembly groove 300, locking pieces 34 are provided on the two side walls of the assembly groove 300, and an unlocking piece 35 is provided on the outer wall of the driving frame 30, an assembly frame 310 adapted to the assembly groove 300 is provided on the upper mold frame 31, and locking areas 311 are provided on both sides of the assembly frame 310, and an inwardly concave heat sealing groove 320 is provided on the ironing plate assembly 32, and length-adjustable needles 321 are provided at the four circumferential corners of the bottom wall of the heat sealing groove 320, and the tip of the needle 321 extends to the outside of the outer opening of the heat sealing groove 320.

[0022] The locking member 34 is a steel ball 340. An inclined slide 301 for rolling fit of the steel ball 340 is provided on the side wall of the assembly groove 300. The lower end of the opening corresponds to the locking area 311 of the assembly frame 310, and the other end corresponds to the unlocking member 35. The unlocking member 35 includes a swing shaft 350 and a magnetic member 351. An arc slide 302 is provided on the outer wall of the assembly frame 310. One end of the arc slide 302 corresponds to the higher end of the opening of the inclined slide 301, and the other end is away from the opening of the inclined slide 301. The magnetic member 351 is located in the arc slide 302 for sliding fit. The tail end of the swing shaft 350 is fixed to the outer wall of the driving frame 30 through a rotating shaft, and the head end is fixedly connected to the magnetic member 351.

[0023] The bottom wall of the heat sealing groove 320 is provided with a through hole 322 for the puncture needle 321 to penetrate, and a heat insulation pad 323 is also provided on the bottom wall of the heat sealing groove 320. After the tip of the puncture needle 321 penetrates the through hole 322, it pierces the heat insulation pad 323 and extends to the outside of the heat sealing groove 320. The tail end of the puncture needle 321 is provided with a bolt rod 324, and a nut 325 is matched on the bolt rod 324. The heat insulation pad 323 is a sponge pad, which is glued to the bottom wall of the heat sealing groove 320 by glue.

[0024] Working principle: Place the package to be sealed on the lower mold assembly 2, which is driven by the cylinder to move to the bottom of the upper mold assembly 3, and the film covering assembly 4 conveys the packaging film between the upper mold assembly 3 and the lower mold assembly 2. Then the upper mold assembly 3 is driven by the cylinder to move toward the lower mold assembly 2, and the packaging film is covered on the package. The ironing plate assembly 32 fixes the packaging film on the edge of the package. At the same time, the annular cutter 33 cuts the packaging film, and the needle 321 quickly pierces small holes around the sealing film of the package. Then the upper mold assembly 3 is reset, and the lower mold assembly 2 moves with the finished package. The small holes play the role of realizing the circulation of gas between the package and the outside, extending the shelf life of the food in the package.

[0025] When sealing the packaging boxes of different models, the upper mold frame 31 can be directly replaced. The ironing plate assembly 32 and the annular cutter 33 assembly are both fixed on the upper mold frame 31, and can be directly replaced together when the upper mold frame 31 is replaced. The assembly frame 310 is fixed in the assembly groove 300 on the driving frame 30. When the assembly frame 310 enters the assembly groove 300, the steel ball 340 will automatically move along the slope of the inclined slide 301 to the end with the lower opening, and the steel ball 340 will be stuck in the locking area 311, which plays a role of pre-assembly, and then the driving frame 30 and the assembly frame 310 are fixed and matched by bolts. During disassembly, even if the bolts are disassembled, the two cannot be disassembled due to the limitation of the steel ball 340, which has a self-locking effect and plays a role in preventing it from being disassembled by mistake. Before disassembly, the swing shaft 350 is rotated to move the magnetic member 351 on the swing shaft 350 to the open end of the inclined slide groove 301. After the magnetic member 351 attracts the steel ball 340, the steel ball 340 is separated from the locking area 311. At this time, the driving frame 30 and the assembly frame 310 can be disassembled, which facilitates the disassembly and replacement of part of the upper mold assembly 3, so that the specifications of the ironing plate assembly 32 and the annular cutter 33 assembly are suitable for packaging boxes of different sizes.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
