[0043] The first conveyor line 2 is divided into a loading section 21 and a strapping section 22 along its conveying direction, and further includes two rows of strapping stations 4 corresponding to the two strapping sections 22. Each row of strapping stations 4 includes a plurality of strapping stations 4 arranged at intervals along the conveying direction of the strapping section 22.

[0044] Workers fill a preset weight of fillings into cups in the loading section 21. The filling of one cup is the amount of filling for one zongzi. The filled cups are transported to the bundling section 22 by the first conveyor line 2. Workers in the bundling station 4 take the cups with fillings from the bundling section 22, pour them into the zongzi leaf cavity they have folded, and start bundling. At the same time, they put the empty cups on the second conveyor line 3. The second conveyor line 3 transports the empty cups back, and the empty cups can eventually return to the loading section 21, forming a cycle. In this way, the weight of the fillings of the zongzi is more accurate, the workers' bundling speed is faster, the layout of the entire production line is more reasonable, the efficiency of making zongzi is effectively improved, and the quality of the zongzi is guaranteed.

[0045] Specifically, the first conveyor line 2 includes a first conveyor belt 23, which includes a first driving wheel 231, a first driven wheel 232, a first chain plate 233 and a first motor 234. The second conveyor line 3 includes a second conveyor belt 31, which includes a second driving wheel 311, a second driven wheel 312, a second chain plate 313 and a second motor 314.

[0046] The frame 1 is provided with a first drive shaft 5 and a second drive shaft 6, the first driving wheel 231 is fixed on the first drive shaft 5, the second driven wheel 312 is rotatably connected to the first drive shaft 5, the first motor 234 drives the first drive shaft 5 to rotate, the second driving wheel 311 is fixed on the second drive shaft 6, the first driven wheel 232 is rotatably connected to the second drive shaft 6, the second motor 314 drives the second drive shaft 6 to rotate, the first chain plate 233 is transmission-connected to the first driving wheel 231 and the first driven wheel 232, and the second chain plate 313 is transmission-connected to the second driving wheel 311 and the second driven wheel 312;

[0047] When the first driving shaft 5 rotates, it drives the first driving wheel 231 to rotate, while the second driven wheel 312 is rotatably connected to the first driving shaft 5. Therefore, at this time, the second driven wheel 312 does not rotate with the first driving shaft 5. The first driving wheel 231 drives the first chain plate 233 to move, and the first driven wheel 232 only supports the movement of the first chain plate 233. Similarly, when the second driving shaft 6 rotates, it drives the second driving wheel 311 to rotate, while the first driven wheel 232 is rotatably connected to the second driving shaft 6. At this time, the first driven wheel 232 does not rotate with the second driving shaft 6. The second driving wheel 311 drives the second chain plate 313 to move, and the second driven wheel 312 only supports the movement of the second chain plate 313.

[0048] With this structure, the first conveyor belt 23 and the second conveyor belt 31 can be arranged side by side on one frame 1, which has a compact structure and does not require too many drive shafts.

[0049] In this embodiment, the first driving wheel 231 and the second driving wheel 311 are gear structures, and the first driven wheel 232 and the second driven wheel 312 are pulley structures.

[0050] Preferably, the first conveyor line 2 can be formed by docking two or more first conveyor belts 23, and the second conveyor line 3 can also be formed by docking two or more second conveyor belts 31. One first conveyor belt 23 serves as the loading section 21, and the other first conveyor belt 23 serves as the bundling section 22, which makes the layout simpler.

[0051] In this embodiment, a partition is provided between the first conveyor line 2 and the second conveyor line 3, which is mainly used to distinguish the first conveyor line 2 and the second conveyor line 3, to avoid workers making mistakes when placing empty cups, and to avoid mixing of cups on the first conveyor line 2 and the second conveyor line 3.

The cylinder 71 drives the paddle 72 to move horizontally, and the moving direction of the paddle 72 is perpendicular to the conveying direction of the first conveyor line 2.

[0053] When the empty cup on the second conveyor line 3 moves to the position corresponding to the material diverter mechanism 7, the cylinder 71 is activated, causing the diverter 72 to move and push the empty cup to one of the first conveyor lines 2. When the next empty cup comes over, the cylinder 71 moves again and pushes the empty cup to the other first conveyor line 2.

[0054] In this embodiment, a first track 8 is provided above the bundling section 22, and a second track 9 is provided below the bundling section 22. Both the first track 8 and the second track 9 extend along the conveying direction of the bundling section 22. The first track 8 is used to place empty boxes, and the second track 9 is used to place boxes filled with rice dumplings.

[0055] When workers are wrapping rice dumplings at the bundling station 4, the wrapped rice dumplings will be placed in a box. After the box is full, it will move to the second track 9. The box can move along the second track 9 and be transported to the next process. After the rice dumplings are taken away in the next process, the empty box will be placed on the first track 8. The empty box can move along the first track 8 to reach each bundling station 4 for workers to take.

[0056] In this embodiment, the second track 9 includes two side plates 91 arranged at intervals and rollers 92 connecting the two side plates 91. The side plates 91 extend along the conveying direction of the strapping section 22. There are multiple rollers 92 and they are arranged at intervals along the extension direction of the side plates 91. The boxes can be placed on the rollers 92 and moved by relying on the rollers 92.

[0057] The structure of the first rail 8 is similar to that of the second rail 9 .

The side panels 91 are mounted on multiple cross beams 122 and fixedly connected to the cross beams 122. The second track 9 will be located between the two supporting legs 121. Of course, the distance between the roller 92 and the frame 11 is sufficient for a box full of rice dumplings to enter.

[0060] In this embodiment, a limit block 123 is fixed on the crossbeam 122. The limit block 123 is located between the side plate 91 and the support leg 121. A notch is provided on the limit block 123. The notch cooperates with the support leg 121 to form a positioning hole.

[0061] A mounting tube 124 is provided between the side panel 91 and the support leg 121. The mounting tube 124 is passed through a plurality of positioning holes, so as to be supported by a plurality of limit blocks 123. There are two mounting tubes 124 corresponding to the two side panels 91.

The operating table 41 includes a bracket 411, a table top 412 arranged on the top of the bracket 411, and a supporting frame 413. The supporting frame 413 connects the bracket 411 and the mounting tube 124. A slide groove for placing the box is provided on the supporting frame 413. The box can be pushed from the slide groove to the second track 9, which is more convenient. Workers can easily push the box onto the second track 9.

[0063] Specifically, the supporting frame 413 includes two L-shaped support plates 4131 arranged at intervals, and a retaining edge 4132 is provided on the side of the support plate 4131 away from the other support plate 4131, and a slide groove is formed between the two retaining edges 4132. The support plate 4131 includes a vertical section and a horizontal section. The vertical section is fixedly connected to the bracket 411, and the end of the horizontal section away from the vertical section is placed on the mounting tube 124, so that the support plate 4131 can be higher than the side plate 91, so that the box can slide onto the second track 9.

[0064] Preferably, the mounting tube 124 is a square tube, and the carrying frame 413 includes a gusset plate 414 located below the support plate 4131. The gusset plate 414 connects the ends of the two horizontal sections away from the vertical section. The cross-section of the gusset plate 414 in the direction perpendicular to the support rod is an inverted U-shape, so that the gusset plate 414 can be buckled on the mounting tube 124, and the mounting tube 124 is used to support the operating table 41.
