[0002] Plastic packaging is a type of packaging product made primarily from synthetic or natural polymer resins, with added additives and manufactured through specific processes. It features excellent physical and mechanical properties, superior barrier properties, strong chemical resistance, and wide processing adaptability. Hot pressing is a simple and common processing method in the plastics industry. It mainly involves heating a mold, injecting a sample, using pressure to fix the mold to a heating plate, controlling the melting temperature and time of the sample, allowing it to melt, harden, cool, and then the finished product is removed from the mold.

[0003] Thermoforming of plastic packaging involves heating and softening plastic sheets or films, applying pressure to conform them to the mold surface, and then cooling to obtain the desired shape of the packaging product. In Chinese utility model patent CN210336633U, entitled "A Thermoforming Device for Plastic Packaging Boxes," the material is placed in a shaping mold, and a hydraulic cylinder lowers the shaping platen to shape the plastic packaging box. However, in the aforementioned application and existing technology, the molding mold is generally installed and disassembled using multiple screws. This requires the removal and installation of multiple screws during both installation and operation, which is cumbersome. Frequent screw tightening and loosening can lead to screw wear and loosening, resulting in low stability during mold installation and affecting the precision of plastic packaging molding.

[0056] Figures 1 to 6 The diagram shown is a structural schematic of an embodiment of the plastic packaging thermoforming apparatus of this utility model. The plastic packaging thermoforming apparatus includes a base platform 1 and a top platform 2, with the top platform 2 positioned above the base platform 1. The base platform 1 and the top platform 2 are connected by multiple support columns 3.

[0057] The lower convex mold 4 and the upper concave mold 5 are arranged above the upper concave mold 5 and are located between the device base 1 and the device top 2. The lower convex mold 4 and the upper concave mold 5 are used to perform thermoforming on plastic packaging.

[0058] The assembly and disassembly unit is connected to one side of both the lower convex mold 4 and the upper concave mold 5. The assembly and disassembly unit is used to install and disassemble the lower convex mold 4 and the upper concave mold 5. The lower assembly and disassembly unit is connected to the top of the device base 1, and the upper assembly and disassembly unit is connected to the top of the power assembly 6.

Two symmetrically distributed disassembly and assembly components 8 are slidably disposed on the surface of the support component 7, and a locking component 9 is disposed at each disassembly and assembly component 8.

[0060] In this technical solution, the lower convex mold 4 and the upper concave mold 5 can be installed and disassembled using the disassembly and assembly unit. The operation is simple, without the need for frequent disassembly and assembly of screws, and multiple disassembly and assembly will not cause wear. This increases the stability of the installation of the lower convex mold 4 and the upper concave mold 5, and ensures the accuracy of thermoforming of plastic packaging.

[0061] The power assembly 6 includes a lifting device 61, which is connected to the bottom of the device top platform 2, and the bottom of the lifting device 61 is connected to the disassembly and assembly unit located above.

[0062] A plurality of guide posts 62 are connected between the base platform 1 and the top platform 2 of the device, and the surface of the guide posts 62 is slidably connected to two disassembly and assembly units.

[0063] In this technical solution, the power component 6 is used to enable the upper concave mold 5 to move up and down, thereby allowing the lower convex mold 4 and the upper concave mold 5 to move closer or further apart, thus realizing the thermoforming of plastic packaging.

[0064] When in use, the plastic packaging material is placed on the lower convex mold 4, and then the lifting device 61 is used to drive the disassembly unit and the upper concave mold 5 located above to move in the same direction along the guide column 62, so that the upper concave mold 5 and the lower convex mold 4 are in contact and the plastic packaging material is hot-pressed into shape.

[0065] Once completed, the lifting device 61 moves the upper concave mold 5 and other structures upward, at which point the formed plastic package can be removed.

[0066] The support assembly 7 includes two fixed shafts 71, which are symmetrically distributed, and each of the two fixed shafts 71 is connected to a mounting bracket 72 at both ends.

[0067] Two symmetrically distributed sliding blocks 73 are slidably connected to the surfaces of the two fixed shafts 71.

[0068] In this technical solution, the position of the assembly / disassembly assembly 8 can be controlled by the support component 7, thereby installing and fixing the lower convex mold 4 and the upper concave mold 5.

[0069] The mounting bracket 72 has two reinforcing plates 76 connected to its side, and the reinforcing plates 76 are slidably connected to the surface of the guide post 62.

[0070] In this technical solution, the stability of the mounting bracket 72 structure can be increased by reinforcing plate 76.

[0071] The mounting bracket 72 is connected to a plurality of mounting posts 77 on one side, and one end of the plurality of mounting posts 77 is connected to the support plate 78.

[0072] In this technical solution, the mounting columns 77 and support plates 78 can be used to connect the mounting brackets 72 on both sides, thereby increasing the overall stability of the support assembly 7.

[0073] The upper support plate 78 is connected to the bottom end of the lifting device 61, and the lower support plate 78 is connected to the top of the device base 1.

[0074] The disassembly assembly 8 includes multiple anti-detachment sliders 81, and the multiple anti-detachment sliders 81 are slidably connected to the inside of the fixed frame 74.

[0075] The anti-detachment slider 81 is connected to a connecting post 82 on one side, and the surface of the connecting post 82 is slidably connected to one side of the fixed frame 74.

[0076] The end of the connecting post 82 away from the anti-detachment slider 81 is connected to a movable plate 83. The side of the movable plate 83 away from the connecting post 82 is connected to a disassembly post 84. The lower convex mold 4 and the upper concave mold 5 are both provided with mounting grooves on their sides. The inner diameter of the mounting groove is larger than the diameter of the disassembly post 84.

[0077] In this technical solution, the lower convex mold 4 and the upper concave mold 5 can be installed and disassembled using the disassembly and assembly component 8.

[0078] In use, depending on the different positions of the mounting grooves on the sides of the lower convex mold 4 and the upper concave mold 5, the sliding column 91 is slid, thereby driving the connecting column 82 and the moving plate 83 to move in the same direction, and then driving the disassembly column 84 to move in the same direction, thereby moving the anti-detachment slider 81 to the position aligned with the mounting groove.

[0079] Then, the telescopic device 75 drives the fixed frame 74 to move in the same direction, which in turn drives the sliding block 73 to move in the same direction along the fixed shaft 71, which in turn drives the anti-detachment slider 81 and the disassembly column 84 to move in the same direction, thereby moving the disassembly column 84 into the mounting groove of the lower convex mold 4 or the upper concave mold 5, completing the installation and fixing of the lower convex mold 4 or the upper concave mold 5.

[0080] Disassembly can be performed using the reverse method.

[0081] The locking assembly 9 includes a sliding post 91, which is connected to one side of the anti-detachment slider 81. The surface of the sliding post 91 is slidably connected through to one side of the fixed frame 74.

[0083] In this technical solution, the position of the disassembly and assembly component 8 can be locked by the locking component 9, thereby adapting to the lower convex mold 4 or upper concave mold 5 with different hole positions.

[0085] One end of the fixing stud 95 is threadedly connected to a locking nut 96, and one side of the locking nut 96 contacts one side of the locking plate 94.

[0086] In this technical solution, the position of the locking plate 94 can be limited by the locking nut 96.

[0087] An elastic reset member 97 is connected between the locking plate 94 and the fixed frame 74, and the elastic reset member 97 is sleeved on the outside of the fixed stud 95.

[0088] In this technical solution, the elastic reset member 97 facilitates the return of structures such as the sliding block 73 to their initial position.

[0089] After the position of the disassembly column 84 is adjusted, rotate the locking nut 96 to move it down along the fixing stud 95, thereby moving the locking plate 94 down, which in turn moves the locking tooth plate 93 down, so that the locking tooth plate 93 and the moving tooth plate 92 are engaged, thereby locking the position of the moving tooth plate 92 by the locking tooth plate 93, and thus locking the position of the sliding column 91 and the anti-detachment slider 81, thereby locking the position of the disassembly column 84.

[0090] The lifting device 61 and the telescopic device 75 are electric push rods, lifting motors, hydraulic lifting cylinders, or other devices with autonomous telescopic functions.

[0091] The elastic reset component 97 is a spring or other component with elastic reset function.
