The multiple groups of first conveying platforms 111 can be staggered with each other, or the multiple groups of second conveying platforms 112 can be staggered with each other, or the first conveying platforms 111 and the second conveying platforms 112 can be staggered, that is, they are arranged according to the height of the molding mold 5 and the angle at which the top edge of the molding mold 5 is tilted upward or downward along the first direction, so that the conveying surface is set along the up and down slopes and the left and right curvatures of the molding mold 5.

[0056] Specifically, the connection component 12 can be connected between multiple groups of first conveying tables 1111, between multiple groups of second conveying tables 1121, or between the first conveying table 1111 and the second conveying table 1121, so as to form a conveying surface with the first conveying table 1111 and the second conveying table 1121.

[0057] In addition, it should be noted that a conveying component is provided on the first conveyor platform 111 and the second conveyor platform 112, and the conveying component can specifically be a conveyor belt and a transmission wheel, or other components that can realize material transmission; and the first conveying table surface 1111 of each first conveyor platform 111 and the second conveying table surface 1121 of the second conveyor platform 112 are both conveying surfaces of the transmission component.

[0058] See also Figure 2 and Figure 3 In some embodiments, a first support frame 1112 is disposed under the first conveying table 1111, and a second support frame 1122 is disposed under the second conveying table 1121; wherein a guide assembly 3 is disposed between two adjacent groups of first support frames 1112 and second support frames 1122.

[0059] Optionally, the guide assembly 3 can be connected between the first support frame 1112 and the first support frame 1112 , between the first support frame 1112 and the second support frame 1122 , and between the second support frame 1122 and the second support frame 1122 .

[0060] Specifically, at least one guide assembly 3 may be provided for each group, and the guide assembly 3 may be a quick clamp for realizing positioning and guiding between two adjacent groups of first support frames 1112 and second support frames 1122, while avoiding relative movement between adjacent first support frames 1112 and second support frames 1122.

[0061] It should be noted that the first support frame 1112 and the second support frame 1122 are also provided with connectors for positioning connection with the ground. After the position of the conveyor line is determined, the first support frame 1112 and the second support frame 1122 can be limited at a specified position; optionally, threaded connectors are used for connection; or other devices capable of achieving limitation are provided at the bottom.

[0062] To facilitate quick assembly, 3-4 commonly used first conveying tables 1111 and second conveying tables 1121 can be designed according to the edge inclination angles of the commonly used forming molds 5, as well as the arcs close to or away from the center line 6, and the corresponding first support frames 1112 and second support frames 1122 can be assembled according to the height of the forming mold 5 to form a variety of first conveying tables 111 and second conveying tables 112; when it is necessary to assemble the conveyor line, directly select the appropriate first conveying table 111 and second conveying table 112 and install the guide assembly 3 and the connection assembly 12 to achieve rapid configuration and form a corresponding conforming production line.

[0063] See also Figure 4 In some embodiments, the connecting assembly 12 includes an intermediate shaft 121 and a conical roller 122; the intermediate shaft 121 is arranged between the first conveying table 1111 and the second conveying table 1121, and is extended radially along the arc connection; the conical roller 122 is sleeved on the intermediate shaft 121 and is rotatably connected to the intermediate shaft 121; the radial cross-section of the conical roller 122 gradually decreases toward the direction approaching the forming mold 5.

[0064] By providing the conical roller 122, the connecting portion of the conical roller 122 can form the above-mentioned conveying surface with the first conveying table 1111 and the second conveying table 1121. It should be understood that when the first conveying table 1111 and the second conveying table 1121 extend to the arc-shaped connection and connect, an angle greater than 90 degrees and less than 180 degrees is usually formed. If only a plane connection is used, material accumulation is likely to occur. Therefore, in the present application, by providing the conical roller 122, material accumulation at the connection can be avoided.

[0067] By providing the retaining edge 15 and the protective support 16, it is prevented that the material deviates from the conveying line during the conveying process, which affects the conveying efficiency and accuracy of the material.

[0068] In order to achieve targeted recycling of the recycling component 4, a detection component is also provided at the recycling port of the recycling component 4 in the present application, which is used to judge the nature of the material, so that abnormal materials and unused materials can be transported to the return vehicle for return processing, or waste materials can be transported to the garbage truck for recycling processing.

[0070] By connecting the control component with the detection device 14, the material arriving at the material picking point 13 can be detected, and the nature of the material arriving at the material picking point 13 can be determined. If it is detected that the material is the material required by the material picking point 13, this section of the transportation task is terminated; if it is detected that the material is one or more of abnormal transportation materials, unused materials or waste materials that are performing a return to warehouse task, it is directly transported to one end of the recovery component 4; if it is detected that the material does not belong to the above two situations, it continues to be transported to the next material picking point 13 for judgment; so that the detection device 14 can realize automatic identification of the material and improve the transportation efficiency.

[0071] Optionally, a plurality of groups of moving wheels 17 are spaced apart at the bottom of the first support frame 1112 and the second support frame 1122 .

[0084] In some embodiments, step S100 further includes:

[0085] S140. Determine, according to the height of the forming mold 5, that each preset conveying section uses a first support frame 1112 of different heights to support the first conveying table 1111, and uses a second support frame 1122 of different heights to support the second conveying table 1121; a guide assembly 3 is provided between two adjacent groups of first support frames 1112 and second support frames 1122.

[0086] In addition, it should be noted that after assembling the above-mentioned conveying mechanism 1 and determining the position of the material collection point 13, a detection device 14 needs to be set on the physical conveying line of the conveying component 11, and at least one detection end is set at each material collection point 13 to realize the detection of the material.
