[0034] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0035] As shown in Figure 1- Figure 6 As shown, a high-efficiency food container palletizing device includes:

[0036] The connecting and adjusting palletizing mechanism 2 has symmetrical installation stations at its bottom;

[0037] Support column 1 is fixedly welded to the bottom installation position of the connecting and adjusting stacking mechanism 2;

[0038] The connecting guide mechanism 3 is fixedly mounted at the output end of the connecting and adjusting stacking mechanism 2;

[0039] The fixed material pushing mechanism 4 is fixedly installed on one side of the connection and adjustment stacking mechanism 2.

[0040] The working principle of the above technical solution is as follows:

[0041] During use, one end of the connecting guide mechanism 3 can be fitted against one end of the conveying device. As the conveying device transports the lunchbox towards the inside and top of the connecting guide mechanism 3,

[0042] The lunch box can move from the inside and top of the connecting guide mechanism 3 to the inside of the connecting adjustment and stacking mechanism 2. When the lunch box moves to the bottom inside of the connecting guide mechanism 3, it can be pushed by the fixed pusher mechanism 4, so that the lunch box can be stably moved to the top inside of the connecting adjustment and stacking mechanism 2. Then, under the action of the connecting adjustment and stacking mechanism 2, the lunch box can be pushed and stacked. The overall structure is simple and the operation is convenient and quick.

[0043] In another embodiment, such as Figure 2As shown, the connecting and adjusting stacking mechanism 2 includes a mounting base 21. A first bidirectional threaded rod 22 is movably connected inside the mounting base 21. Both ends of the first bidirectional threaded rod 22 are fixedly connected to first limiting discs 23. A first rotating block 24 is fixedly connected to the side of one of the first limiting discs 23 away from the first bidirectional threaded rod 22. Moving mounting blocks 25 are symmetrically arranged on the outer surface of the first bidirectional threaded rod 22 via threads. A second bidirectional threaded rod 26 is movably connected inside the moving mounting block 25. Both ends of the second bidirectional threaded rod 26 are fixedly connected to second limiting discs 27. A second rotating block 28 is fixedly connected to the side of one of the second limiting discs 27 away from the second bidirectional threaded rod 26. Moving base blocks 29 are symmetrically arranged on the outer surface of the second bidirectional threaded rod 26 via threads. A first limiting rod 210 is fixedly connected to the top of two moving base blocks 29 on the same side, and a second limiting rod 211 is fixedly connected to the top of the other two moving base blocks 29 on the same side. Fixed stacking limiting components 213 are fixedly connected to the second limiting rod 211 at their close proximity. A connecting stacking lifting component 214 is fixedly connected to the bottom end of the mounting block 21. A fixed through groove 212 is provided on the surface of the second limiting rod 211.

[0044] Under the action of the connecting guide mechanism 3 and the fixed pushing mechanism 4, when the lunch box moves to the top of the mounting base 21 and the inside of the first limiting rod 210 and the second limiting rod 211, it can be pushed upward by the connecting stacking lifting component 214. When the lunch box cooperates with the fixed stacking limiting component 213, it can be stacked, making the operation convenient.

[0045] In another embodiment, such as Figure 3 As shown, the connecting guide mechanism 3 includes a fixed guide rod 31 fixedly disposed on the side of the first limiting rod 210 away from the second limiting rod 211, and the other end of the fixed guide rod 31 is topped with a fixed guide rod 31.

[0046] A fixed reinforcing arm 33 is fixedly connected between the part and the side of the first limiting rod 210 away from the second limiting rod 211. A connecting guide block 34 is fixedly connected to one end of the fixed guide rod 31. The outer surface of the connecting guide block 34 slides and fits against the inner side of the fixed through groove 212.

[0047] The lunchbox is easily moved to the inside of the fixed guide rod 31 by the conveying device, and the top edge of the lunchbox can be at the top of the fixed guide rod 31. It can move on the outside of the surface of the fixed guide rod 31 and the connecting guide block 34, and move towards the top of the mounting base block 21, which is convenient to operate.

[0048] In another embodiment, such as Figure 4 As shown, the fixed stacking limiting assembly 213 includes a fixed mounting plate 2131. A connecting sleeve 2132 is fixedly connected to one side of the fixed mounting plate 2131. A fixing spring 2133 is fixedly connected to the end of the connecting sleeve 2132 away from the fixed mounting plate 2131. A connecting mounting plate 2134 is fixedly connected to the other end of the fixing spring 2133. A connecting limiting block 2135 is fixedly connected to the side of the connecting mounting plate 2134 away from the fixing spring 2133. A pressure-bearing inclined surface 2136 is provided at the end of the connecting limiting block 2135 away from the connecting mounting plate 2134.

[0049] When the lunchbox is moved upward by the connecting palletizing lifting component 214, the edge of the lunchbox can compress the pressure slope 2136, allowing the connecting limiting block 2135 to move inward towards the connecting sleeve 2132, pushing the connecting mounting plate 2134 and compressing the fixing spring 2133. When the edge of the lunchbox moves to the top of the connecting limiting block 2135, the fixing spring 2133 can push the connecting mounting plate 2134 and the connecting limiting block 2135 back to their original positions, allowing the connecting limiting block 2135 to lift the edge of the lunchbox. This cycle repeats, enabling the lunchbox to be stacked. The overall structure is simple and easy to operate.

[0050] In another embodiment, such as Figure 5 As shown, the connecting palletizing lifting assembly 214 includes a first electric telescopic rod 2141 symmetrically located at the bottom of the mounting base 21. The output end of the first electric telescopic rod 2141 passes through the interior of the mounting base 21 and extends to the outside. The output end of the first electric telescopic rod 2141 is fixedly connected to a connecting top block 2142, which is located in the middle of the inner side of the top of the mounting base 21.

[0051] The first electric telescopic rod 2141 can push the connecting top block 2142 upward, so that the connecting top block 2142 can push the lunch box upward, making the operation convenient.

[0052] In another embodiment, such as Figure 6 As shown, the fixed pushing mechanism 4 includes a connecting mounting bracket 41 located on one side of the mounting base 21. A second electric telescopic rod 42 is fixedly connected to the top of the connecting mounting bracket 41, and a connecting pushing block 43 is fixedly connected to the output end of the second electric telescopic rod 42.

[0053] The second electric telescopic rod 42 can push the connecting pusher block 43, which in turn pushes the lunch box, allowing the lunch box to move stably to the top of the mounting base block 21, making operation convenient.

[0054] In another embodiment, such as Figure 3 As shown, a fixed arc-shaped groove 32 is provided at the bottom of the other end of the fixed guide rod 31.

[0055] The guide rod 31 is easy to fix. Under the action of the fixed arc groove 32, it can fit against the outer surface of the conveyor belt end inside the conveying device, so as to make stable connection and use and easy to operate.

[0056] The working principle of this utility model is as follows: During use, the connecting and adjusting stacking mechanism 2 is first adjusted according to the size of the lunch box. First, the first rotating block 24 rotates, causing the first limiting plate 23 and the first bidirectional threaded rod 22 to move, allowing the movable mounting block 25 to move between the top of the mounting base 21 and the outer surface of the first bidirectional threaded rod 22, adjusting the distance between adjacent first limiting rods 210 and adjacent second limiting rods 211. Then, the second rotating block 28 rotates, causing the second limiting plate 27 and the second bidirectional threaded rod 26 to rotate, allowing the movable base 29 to move either the first limiting rod 210 or the second limiting rod 211, adjusting the distance between the first limiting rod 210 and the second limiting rod 211. Simultaneously, during the adjustment of the distance between the first limiting rod 210 and the second limiting rod 211, the connecting guide block 34 can move inside the fixed through groove 212, and adjacent first limiting rods 210... During the adjustment of the distance between the adjacent second limiting rod 211 and the adjacent fixed guide rod 31, the distance between the adjacent fixed reinforcing arm 33 and the connecting guide block 34 is also adjusted. Then the whole assembly is placed.

[0057] At the end of the lunchbox conveying device, the fixed guide rod 31, under the action of the fixed arc groove 32, is positioned on the outer side of the inner conveyor belt end surface of the conveying device and fits against each other. Then, the conveying device conveys the lunchbox to the inner side and top of the fixed guide rod 31, so that the bottom of the lunchbox is between the fixed guide rods 31 and the edge of the lunchbox is at the top of the fixed guide rod 31, allowing the lunchbox to move to the inner side and top of the connecting guide block 34. Then, the second electric telescopic rod 42 pushes the connecting push block 43, allowing the connecting push block 43 to push the lunchbox, so that the lunchbox can be stably positioned on the top of the mounting base block 21. Then, the first electric telescopic rod 2141 pushes the connecting top block 2142, pushing the lunchbox, so that the edge of the lunchbox can squeeze the pressure slope 2136, allowing the connecting limiting block 2135 to move inward to the inner side of the connecting sleeve 2132, and to the connecting mounting plate 2134. The push compresses the fixing spring 2133. When the edge of the lunch box moves to the top of the connecting limit block 2135, the fixing spring 2133 can push the connecting mounting plate 2134 and the connecting limit block 2135 back to their original positions, so that the connecting limit block 2135 can lift the edge of the lunch box. This cycle repeats, thus enabling the lunch boxes to be stacked. The overall structure is simple and easy to operate.

[0058] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
