The upper lifting drive unit 21 is transmission-connected with the upper lifting seat 22, and an upper transfer and conveying device 3 is provided on the upper lifting seat 22. The conveying direction of the upper transfer and conveying device 3 is along the front-back direction. The upper lifting drive unit 21 can drive the upper side surface of the upper transfer and conveying device 3 to move up and down to be lower than or higher than the conveying surface of the upper conveying line 1.

[0035] The lower conveying assembly is arranged on the lower side of the upper conveying assembly. The lower conveying assembly includes a lower conveying line 4 extending in the left-right direction. The lower conveying line 4 is arranged on the lower side of the upper conveying line 1. A lower lifting device is provided on the lower conveying line 4. The lower lifting device includes a lower lifting driving unit and a vertically movable lower lifting seat. The lower lifting driving unit is in transmission connection with the lower lifting seat. A lower transfer conveying device 6 is provided on the lower lifting seat. The conveying direction of the lower transfer conveying device 6 is in the front-rear direction. The lower lifting driving unit can drive the upper surface of the lower transfer conveying device 6 to move up and down to be lower than or higher than the conveying surface of the lower conveying line 4.

[0036] The transfer lifting assembly 7 is arranged on the front side or the rear side of the lower conveying line 4 and the upper conveying line 1. In this embodiment, the transfer lifting assembly 7 is arranged on the front side of the lower conveying line 4 and the upper conveying line 1. The transfer lifting assembly 7 includes a first transfer lifting driving unit 71 and a vertically movable first transfer lifting seat 72. The first transfer lifting driving unit 71 is in transmission connection with the first transfer lifting seat 72. A first transfer conveying device is provided on the first transfer lifting seat 72. The conveying direction of the first transfer conveying device is in the front-rear direction. The first transfer conveying device is arranged corresponding to the upper transfer conveying device 3 and the lower transfer conveying device 6 in position. The first transfer lifting driving unit 71 can drive the first transfer conveying device to move up and down to be arranged corresponding to the height of the upper transfer conveying device 3 or the lower transfer conveying device 6.

[0037] The material 8 can be conveyed on the upper conveying line 1 and the lower conveying line 4, and is conveyed between the upper conveying line 1 and the lower conveying line 4, that is, at different heights, through the upper lifting device, the upper transfer conveying device 3, the lower lifting device, the lower transfer conveying device 6 and the transfer lifting assembly 7. For example, when the material 8 is conveyed on the upper conveying line 1, the upper surface of the upper transfer conveying device 3 is lower than the conveying surface of the upper conveying line 1. Refer to Figure 4 ; when the material 8 is conveyed to the upper side of the upper transfer conveying device 3, the upper lifting driving unit 21 drives the upper lifting seat 22 and the upper transfer conveying device 3 to rise, and jacks up the material 8 to be higher than the conveying surface of the upper conveying line 1. Refer to Figure 5, and in the transfer lifting assembly 7, the first transfer lifting drive unit 71 drives the first transfer lifting seat 72 and the first transfer conveyor device to rise to the height of the upper transfer conveyor device 3. Then, the upper transfer conveyor device 3 conveys the material 8 forward to the first transfer conveyor device; subsequently, the first transfer lifting drive unit 71 drives the first transfer conveyor device and the material 8 to descend to the height of the lower transfer conveyor device 6. The material 8 can be taken out at this position for corresponding processing. After the processing is completed, the material 8 is placed back on the first transfer conveyor device. At this time, the upper side surface of the lower transfer conveyor device 6 is higher than the conveying surface of the lower conveyor line 4. The first transfer conveyor device conveys the material 8 backward to the lower transfer conveyor device 6; then, the lower lifting drive unit drives the lower transfer lifting seat and the lower transfer conveyor device 6 to descend to a position lower than the conveying surface of the lower conveyor line 4, so that the material 8 is placed on the lower conveyor line 4, that is, the processed material 8 continues to be conveyed along the lower conveyor line 4.

[0041] The structure of the upper lifting drive unit 21 using the upper lifting cylinder is relatively simple. When the upper lifting seat 22 and the upper transfer and conveying device 3 need to be lifted, the piston rod of the upper lifting cylinder extends. Since the upper base 23 is fixed, the cylinder body of the upper lifting cylinder, the upper lifting seat 22, and the upper transfer and conveying device 3 can rise. The upper lifting seat 22 slides along the upper guide rod 24 to maintain stability, and the structure is relatively compact. In some other embodiments, the upper lifting cylinder can also be arranged on the lower side of the upper base 23.

When it is conveyed to the upper side of the upper transfer and conveying device 3, the upper transfer and conveying device 3 can jack up the material 8 between the two upper conveyor chains 15. The upper conveyor line 1 and the upper transfer and conveying device 3 do not affect each other in conveying the material 8, and the structure is relatively compact and reasonable.

[0046] In some specific embodiments, the upper conveying assembly has the same structure as the lower conveying assembly.
