[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1, please refer to Figure 1-5This utility model provides a continuous modified atmosphere packaging machine, including a base box 1, a support platform 101, a fixed door panel 102, a buckle 103, a rotating shaft 104, a limiting strip 105, a machine body shell 2, a sterilization box 3, a transmission platform 4, a movable base 5, a first pull ring 501, an electric push rod 502, a first connecting block 503, an auxiliary telescopic rod 504, a roller 505, a kit 6, a limiting frame 601, a second pull ring 602, a limiting groove 603, a tray 7, a connecting slide 701, a pressure plate 8, a connecting screw 801, a connecting plate 9, a positioning nut 901, a connecting column 902, a first buffer plate 903, a second buffer plate 904, a buffer block 905, a hydraulic press 906, and a base box. The top of the bottom box 1 is provided with an outer shell 2. Support platforms 101 are fixed on both sides of the top of the bottom box 1. The support platforms 101 are all located inside the outer shell 2. Two sets of fixed door panels 102 are provided on the sides of the support platforms 101. Two sets of rotating shafts 104 are provided at the connection between the fixed door panels 102 and the bottom box 1. Buckles 103 are provided at the connection between the two sets of fixed door panels 102. After the two sets of fixed door panels 102 are rotated and closed and fixed by the buckles 103, the inner kit 6, movable base 5 and pallet 7 can be fixed. By opening the fixed door panels 102, the kit 6, movable base 5 and pallet 7 can be replaced by sliding, which is convenient to adapt to different packaging needs.

[0025] Specifically, such as Figure 1 and Figure 4 As shown, a disinfection box 3 is installed on one side of the outer shell 2. A transmission platform 4 is set on one side and inside the disinfection box 3. Two sets of kits 6 are slidably connected inside the bottom box 1. The kit 6 is set as a half-rectangular frame structure, and a second pull ring 602 is set on the side of the kit 6 near the fixed door panel 102. A limit frame 601 is fixed at the bottom of the kit 6. The inner width of the limit frame 601 is smaller than the inner width of the kit 6. In this way, the limit frame 601 at the bottom of the kit 6 can prevent the tray 7 from falling out of the inside of the kit 6, limit the movement range of the tray 7, and facilitate the installation and assembly of the tray 7.

[0026] Specifically, such as Figure 3 and Figure 4 As shown, four sets of limiting strips 105 are fixed on the inner side of the base box 1 near the kit 6. The limiting strips 105 are distributed on both sides of the two kits 6 near the support platform 101, and two sets of parallel limiting strips 105 are provided on each side of the two kits 6. The limiting strips 105 allow the two kits 6 to slide and assemble inside the base box 1, which facilitates the replacement of kits 6 with different inner dimensions to adapt to different packaging size limits.

[0027] Specifically, such as Figure 3 and Figure 5As shown, a limiting groove 603 is provided at the connection between the kit 6 and the limiting strip 105. The limiting groove 603 and the limiting strip 105 are slidably connected. A tray 7 is slidably arranged inside the kit 6. A connecting groove 701 is provided at the bottom of the tray 7. A first connecting block 503 is slidably connected inside the connecting groove 701. The cross-section of the first connecting block 503 is a "T" shaped structure. The bottom of the first connecting block 503 is connected to the electric push rod 502. Two sets of auxiliary telescopic rods 504 are also provided at the bottom of both ends of the first connecting block 503. The lower end of the auxiliary telescopic rods 504 is fixedly connected to the movable base 5. The two sets of auxiliary telescopic rods 504 are symmetrically distributed on both sides of the electric push rod 502. In this way, when the electric push rod 502 pushes the first connecting block 503 to move upward, the movement of the first connecting block 503 can be made more stable by the extension and retraction of the auxiliary telescopic rods 504, thereby making the support movement of the tray 7 more stable.

[0028] Specifically, such as Figure 4 and Figure 5 As shown, an electric push rod 502 is provided at the bottom of the pallet 7, and a movable base 5 is provided at the bottom of the electric push rod 502. A first pull ring 501 is fixed on the side of the movable base 5, and four sets of rollers 505 are installed at the bottom of the movable base 5. The movable base 5 is located inside the bottom box 1 and is slidably connected to the bottom box 1. A pressure plate 8 is provided at the top of the pallet 7. The outer dimensions of the pressure plate 8 are consistent with the outer dimensions of the pallet 7, and the shape and size of the pallet 7 and the pressure plate 8 are consistent with the inner shape and size of the two sets of kits 6. The pressure plate 8 and the two sets of kits 6 are slidably connected, which facilitates the sliding of the pallet 7 and the pressure plate 8 inside the kit 6 for packaging processing.

[0029] Example 2, specifically, as follows Figure 2 , Figure 4 and Figure 5 As shown, a connecting plate 9 is provided on the top of the pressure plate 8. The connecting plate 9 is inserted and connected to the connecting screw 801. A positioning nut 901 is rotatably connected to the top of the connecting screw 801. The positioning nut 901 is located on the top surface of the connecting plate 9. The rotation of the positioning nut 901 can connect and fix the connecting plate 9 and the pressure plate 8, which is convenient for replacing the pressure plate 8 below and for adjusting and replacing the lamp according to the kit 6.

[0030] Specifically, such as Figure 2 and Figure 5As shown, a connecting column 902 is vertically fixed to the top center of the connecting plate 9. A first buffer plate 903 is fixed to the top of the connecting column 902 away from the connecting plate 9. A second buffer plate 904 is provided on the top of the first buffer plate 903. Four sets of buffer blocks 905 are provided between the second buffer plate 904 and the first buffer plate 903. A hydraulic press 906 is installed on the top of the second buffer plate 904 away from the connecting plate 9. The top of the hydraulic press 906 is fixedly connected to the inner wall of the outer shell 2 of the machine body. This can drive the pressure plate 8 to move and facilitate the replacement of the pressure plate 8. Four sets of connecting screws 801 are fixed at the connection between the pressure plate 8 and the connecting plate 9.

[0031] In use, this embodiment of the application shows that by providing a slidable and detachable kit 6 on the bottom box 1, the kit 6 can be slidably disassembled, so that different internal sizes of kit 6 can be replaced according to the size of the packaging. At the same time, the tray 7 and the pressure plate 8 are also included. After a set of kits 6 is slidably disassembled, the tray 7 slides, and the bottom connecting groove 701 will also separate from the first connecting block 503, so that the tray 7 can be replaced. By rotating the positioning nut 901, the positioning nut 901 can be removed, so that the pressure plate 8 and the connecting plate 9 can be separated and the pressure plate 8 can be replaced. In this way, the pressure plate 8 and the tray 7 can be replaced in a matching manner with the kit 6.

[0032] The limiting strip 105 fixed inside the bottom box 1 can slide with the limiting groove 603 of the kit 6. First, a set of kits 6 is assembled inside the bottom box 1. Then, the connecting groove 701 at the bottom of the tray 7 is combined with the first connecting block 503 by sliding. Then, another set of kits 6 is assembled inside the bottom box 1 by the limiting strip 105. Then, the door panel 102 is rotated and fixed by the pivot 104. After the door panel 102 is closed and fixed, it can be fixed by the buckle 103. In this way, the installation and fixing of the internal kits 6 and tray 7 can be completed by the door panel 102, which facilitates the matching replacement of kits 6, tray 7 and pressure plate 8. It is also convenient to replace according to the size of the packaging, avoiding the situation where the internal size of kit 6 is too large and the packaging size is too small, making it impossible to better position and fix the packaging.

[0033] The electric push rod 502 that drives the tray 7 to move up and down is set on the movable base 5. After opening the fixed door panel 102, the movable base 5 can be moved by the rollers 505, so that the tray 7 and the electric push rod 502 can be moved out of the bottom box 1 together. Then the electric push rod 502 can be maintained and repaired. The auxiliary telescopic rods 504 on both sides of the electric push rod 502 can also assist the electric push rod 502 in driving the first connecting block 503 to move, increasing the stability of the movement of the first connecting block 503. In this way, the continuous modified atmosphere packaging machine is completed. It should be noted that this utility model is a continuous modified atmosphere packaging machine.
