[0043] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , an embodiment of the utility model provides a shoe last reflux device for an intelligent shoemaking production line, comprising a first frame 1 and a second frame 2, wherein a discharge port 11 is provided on the first frame 1, and a conveying mechanism 3 with two upper and lower layers for conveying shoe lasts (not shown) and trays 6 is provided between the first frame 1 and the second frame 2, and a circulating lifting mechanism 4 for lifting the shoe last and the tray 6 is provided at both ends of the first frame 1 and the second frame 2 corresponding to the conveying mechanism 3, respectively. A transporting robot 5 for transporting the shoe last on the circulating lifting mechanism 4 to the discharge port 11 is provided on one side of the first frame 1 corresponding to the conveying mechanism 3;

[0044] The circulating lifting mechanism 4 includes a circulating lifting frame 41, a lifting drive 42 and a circulating conveying assembly 43 arranged in the circulating lifting frame 41. The lifting drive 42 is used to drive the lifting of the circulating lifting frame 41 so that the circulating lifting frame 41 has a first position and a second position; wherein the lifting drive 42 can be a cylinder or a hydraulic cylinder.

[0045] When the circulating lifting frame 41 is in the first position, the circulating lifting frame 41 is located at the conveying mechanism 3 on the upper layer;

[0046] When the circulating lifting frame 41 is at the second position, the circulating lifting frame 41 is located at the conveying mechanism 3 on the lower layer.

[0047] With the above-mentioned structure, during the transportation of shoe lasts and pallets 6, the lifting driving member 42 of the circulating lifting mechanism 4 drives the lifting of the circulating lifting frame 41 with the cooperation of the upper and lower conveying mechanisms 3 and the circulating lifting mechanisms 4 at both ends of the conveying mechanism 3, so that the circulating lifting frame 41 can move between the first position and the second position, and through the circulating conveying component 43 on the circulating lifting frame 41, after the pallet 6 on the conveying mechanism 3 is conveyed to the circulating conveying component 43, when the circulating lifting frame 41 is lifted to the first position or the second position, the pallet 6 is conveyed to the conveying mechanism 3 of another layer through the circulating conveying component 43, so that it can form a circulating conveyance for the shoe lasts and pallets 6, and can transport the shoe lasts with the cooperation of the transporting robot 5, avoiding manual handling and recovery of shoe lasts, tooling boards, shoe bodies and other objects, reducing manual labor, improving transportation efficiency, and thus preventing shoe last wear.

[0048] In one embodiment, see Figure 4 、 Figure 5 and Figure 6 The circulating conveying assembly 43 includes a circulating transmission shaft 431, a driving wheel set 432, a fixed wheel set 433, and a tensioning wheel set 434. The driving wheel set 432 is mounted on the circulating transmission shaft 431. The driving wheel set 432, the fixed wheel set 433, and the tensioning wheel set 434 are all connected by a circulating conveyor belt (not shown). The circulating transmission shaft 431 is driven by a circulating motor. In actual use, after the circulating motor drives the circulating transmission shaft 431, the circulating transmission shaft 431 drives the driving wheel set 432 to rotate. Under the transmission of the circulating conveyor belt, the fixed wheel set 433 and the tensioning wheel set 434 can be driven to rotate, thereby transporting the pallets 6 on the circulating conveyor belt toward the conveying mechanism 3.

[0049] The circulating lifting frame 41 has a feed port 411 at one end facing the conveyor mechanism 3. A transition piece 7 is installed at the position corresponding to the feed port 411. The transition piece 7 includes a transition rod 71, with both ends of the transition rod 71 mounted to the circulating lifting frame 41 via support rods 72. In actual use, the transition rod 71 of the transition piece 7 can serve as a transition for the passing pallets 6, allowing the pallets 6 to be conveyed to the conveyor mechanism 3 more smoothly.

[0050] In one embodiment, see Figure 2 、 Figure 3 and Figure 6The two layers of conveying mechanisms 3 have one end as the feed end and the other end as the discharge end, and the feed ends of the conveying mechanisms 3 on both sides are staggered. That is, the feed end of the upper conveying mechanism 3 corresponds to the discharge end of the lower conveying mechanism 3, and the discharge end of the upper conveying mechanism 3 corresponds to the feed end of the lower conveying mechanism 3. This allows the upper conveying mechanism 3 and the lower conveying mechanism 3 to convey in opposite directions, and cooperate with the circular lifting mechanisms 4 at both ends to form a circular conveying.

[0051] The discharging end of the conveying mechanism 3 is provided with a transition piece 7, which includes a transition rod 71. Both ends of the transition rod 71 are mounted on the conveying mechanism 3 via support rods 72. In actual use, the transition rod 71 of the transition piece 7 can serve as a transition for the passing trays 6, allowing the trays 6 to be conveyed to the circulating lifting mechanism 4 more smoothly.

[0052] The conveying mechanism 3 includes a transport track 31 and a transport assembly 34. A feed rack 32 and a discharge rack 33 are mounted on the first frame 1 and the second frame 2, respectively, at either end of the transport track 31. The transport assembly 34 is driven by a transport motor 35. In actual operation, the transport assembly 34 driven by the transport motor 35 drives the pallet 6 to move along the transport track 31, thereby transporting the pallet 6 toward the discharge end.

[0053] The two inner side walls of the feed rack 32 are provided with inclined guide grooves 321. In actual use, the provision of the guide grooves 321 can guide the movement of the tray 6 during the process of being transported from the circulating lifting mechanism 4 to the feed rack 32, making it easier for the tray 6 to be transported to the feed rack 32.

[0054] The transport assembly 34 includes a transport drive shaft 341 mounted on the discharge rack 33, a transport driving wheel set 342 mounted on the transport drive shaft 341, and a transport driven wheel set 343 mounted on the feed rack 32. The transport driving wheel set 342 and the transport driven wheel set 343 are connected by a transport conveyor belt (not shown). The output end of the transport motor 35 is connected by a transport drive shaft 341. In actual use, after the transport motor 35 drives the transport drive shaft 341, the transport drive shaft 341 drives the transport driving wheel set 342 to rotate, and cooperates with the transport conveyor belt and the transport driven wheel set 343 to enable the transport conveyor belt to transport the pallet 6.

[0055] A support plate 36 for supporting the conveyor belt is provided on the feed rack 32 and the discharge rack 33. In actual use, the support plate 36 can support the conveyor belt and prevent the conveyor belt from sinking due to the excessive weight of the pallet 6.

[0056] The position of the corresponding transport conveyor belt is provided with an indented guide groove 361 on the support plate 36, and the transport conveyor belt is arranged in the guide groove 361. In actual use, the provision of the guide groove 361 can play an anti-deviating effect on the transport conveyor belt.

[0058] Those skilled in the art will appreciate that the above embodiments are merely intended to clearly illustrate the present invention and are not intended to limit the scope of the present invention. Other variations or modifications may be made based on the above-described utility model, and such variations or modifications are still within the scope of the present invention.
