[0036] In this embodiment, if Figure 3 As shown, when it is necessary to compress the container bags in the inner box 3, the first motor 9 is started first, so that the first driving block 11 can drive the first driven block 12 to rotate, so that the rotating shaft 13 can rotate in the first shell 5, and then the extrusion assembly can extend in the second slot 8, so that the container bags in the inner box 3 can be compressed. In this process, when one of the rotating shafts 13 rotates, the transfer rod 14 can drive the designated transfer seat 21 to rotate, so that the first rotating rod 17 can drive the second rotating rod 19 to rotate through the meshing effect of the second driving block 18 and the second driven block 20, so that the effect of one first motor 9 driving multiple rotating shafts 13 to rotate synchronously can be achieved, so that multiple extrusion assemblies can squeeze different positions of the container bags in multiple directions in the inner box 3, so that the container bags can be squeezed more thoroughly;

[0037] The driving assembly includes a first transmission shaft 29, a positioning frame 25 and a driven shaft 28, and a plurality of the positioning frames 25 are respectively fixed at the four corners of the outer box 1, and the two ends of the driven shaft 28 pass through the positioning frames 25 and are rotatably connected with the positioning frames 25, and a driving wheel 27 is fixedly arranged on the driven shaft 28, and the driving wheel 27 is meshed with the vertical plate 26.

A second motor 24 is fixedly arranged on the inner wall of the outer box 1, and the output end of the second motor 24 is provided with a first transmission shaft 29 connected to one of the first transmission shafts 29, and the controller 4 can control the first motor 9 and the second motor 24;

[0038] In this embodiment, the plurality of second shells 16 can play a role of transfer transmission. As the container bags are stored, the positions of the first shell 5 and the second shell 16 need to be raised in sequence. At this time, the second motor 24 is started. The first motor 9 and the second motor 24 can both be servo motors. After the second motor 24 is started, the first transmission shaft 29 can drive the driven shaft 28 to rotate through the action of the universal joint, and then the plurality of driving wheels 27 can be rotated synchronously. The universal joint is a universal coupling, and specifically, a SWP universal joint coupling can be used. The driving wheel 27 can drive the vertical plate 26 to rise and fall through the action of meshing. Furthermore, multiple guide blocks 22 can be raised and lowered synchronously along the guide rod 23, so that multiple first shells 5 and second shells 16 can be raised and lowered along the inner box 3, which can improve the stability of the first shell 5 and the second shell 16 during lifting. A second motor 24 can drive multiple driving wheels 27 to rotate synchronously, so that the force on multiple vertical plates 26 can be more evenly applied, thereby improving the smoothness of the guide block 22 during lifting. An independent power supply can be set in the controller 4 to provide power to the first motor 9 and the second motor 24. There is no mandatory regulation for the control circuits of the first motor 9 and the second motor 24.

[0039] In this embodiment, a spring 15 is provided inside the rotating shaft 13, one end of the transfer rod 14 is inserted into the cavity and connected to one end of the spring 15, a card slot is provided inside the transfer seat 21, and the other end of the transfer rod 14 is inserted into the card slot. When the parts on the first shell 5 and the second shell 16 are damaged, they need to be replaced separately. The transfer rod 14 is taken out and the spring 15 is compressed, so that one end of the transfer rod 14 can be separated from the card slot, so that the second shell 16 can be separated from the first shell 5, which is convenient for the separate disassembly and replacement of the second shell 16 and the first shell 5. The cross section of the transfer rod 14 is as shown in FIG. Figure 5 As shown, the transmission efficiency of the rotating shaft 13 and the transfer rod 14 can be improved, and the stability of the rotating shaft 13 and the transfer rod 14 during transmission can be ensured.

[0040] Furthermore, the extrusion assembly adopts an arc rod 7, and one end of the arc rod 7 is also provided with a pressing assembly, through which the arc rod 7 can limit the periphery of the container bag, so that the periphery of the container bag is not easy to warp, and the container bag can be compressed by the pressing assembly.

[0041] In this embodiment, the pressing assembly includes a second transmission shaft 32 and a limiting rod 30. The second transmission shaft 32 is fixedly arranged at one end of the arc rod 7 away from the first shell 5. A positioning rod is rotatably arranged on the second transmission shaft 32.

The lower end of the arc rod 7 is provided with an arc-shaped elastic plate 31 connected to the bottom of the limiting rod 30. When the pressing assembly presses the container bag, the limiting rod 30 is in a closed position. The pressure block at the bottom will first contact the container bag. As the arc rod 7 is moved, the limit rod 30 can compress the arc elastic plate 31. The arc elastic plate 31 can be a metal elastic plate. The two pressure blocks on the limit rod 30 can both contact the container bag, which can improve the compression effect on the container bag. When the second batch of container bags are placed, the periphery of the second batch of container bags will cover the limit rod 30. As the arc rod 7 is moved, the limit rod 30 can be detached from the periphery of the second batch of container bags, so that the second batch of container bags can be compressed again.

[0042] In this embodiment, the second shell 16 is L-shaped, and the second shell 16 and the first shell 5 are both set to be smooth planes, which can reduce the friction between the second shell 16 and the first shell 5 and the outer wall of the inner box 3.

[0043] In this embodiment, first locating bearings are inlaid at both ends of the first shell 5, and the first locating bearings are penetrated by the rotating shaft 13. Second locating bearings are inlaid at both ends of the second shell 16, and the second locating bearings are respectively penetrated by the first rotating rod 17 and the second rotating rod 19. A third locating bearing is inlaid on the fixed seat, and the third locating bearing is penetrated by the first transmission shaft 29. A fourth locating bearing is inlaid in the middle part of the positioning frame 25, and the fourth locating bearing is penetrated by the driven shaft 28. The rotating shaft 13, the first rotating rod 17, the second rotating rod 19, the first transmission shaft 29 and the driven shaft 28 can be limited by the first locating bearing, the second locating bearing, the third locating bearing and the fourth locating bearing, respectively, so that the smoothness of the rotating shaft 13, the first rotating rod 17, the second rotating rod 19, the first transmission shaft 29 and the driven shaft 28 during rotation can be improved.

[0044] In this embodiment, a plurality of grooves are provided on the outer wall of the inner box 3, and the first shell 5 can slide and rise and fall inside the grooves, and the grooves are rectangular. Through the provided grooves and the cooperation between the grooves and the first shell 5, the smoothness of the first shell 5 during lifting and lowering can be improved.

[0045] In this embodiment, the arc rod 7 can pass through the second empty groove 8 and is located between the outer box 1 and the box cover 2. The initial position of the arc rod 7 is between the outer box 1 and the box cover 2, which will not affect the storage of the container bag inside the inner box 3. In addition, in this structure, a slider can be temporarily set on the first shell 5, and a plurality of vertical rods passing through the slider can be set between the outer box 1 and the box cover 2, so as to position the first shell 5 to ensure the stability of the first shell 5 when it is raised or lowered.
