[0034] like Figure 1 As shown, the shoe upper feeding mechanism of this embodiment includes a base 2, on which side plates 51 arranged at intervals support and install supports 5. Pressing components 4 are respectively installed on the base 2 on both sides of the supports 5, and lifting components 3 are installed on the base 2 between the two side plates 51; Figure 2 As shown, the support 5 has a through hole running vertically, and the side plate 51 has symmetrical L-shaped grooves 511. The lifting assembly 3 moves along the L-shaped grooves 511 until the limiting block 38 in the lifting assembly 3 moves upward into the hole of the support 5.

[0035] In this embodiment, by placing the lifting component 3 between the base 2 and the support 5, the lifting component 3 can move upward to the opening of the support 5 via the L-shaped slide 511 in the horizontal and vertical directions to position the shoe upper 10 during loading. Afterward, the lifting component 3 can retract along the L-shaped slide 511 away from the opening, especially freeing up the space below the support 5, which facilitates the shoelace-threading operation of the external clamping mechanism.

[0037] In actual use, the movable seat 32 moves horizontally relative to the side plate 51 along the movable guide 33 under force, driving the support shaft 35 to move synchronously along the horizontal direction of the L-shaped slide groove 511, and the limiting block 38 moves closer to the support 5 in the horizontal direction; when the support shaft 35 moves to the corner of the L-shaped slide groove 511, the support shaft 35 is guided by the L-shaped slide groove 511 and rises, the lifting seat 37 moves upward with the support shaft 35, and the four sets of connecting rods 34 rotate upward relative to the movable seat 32, such as Figure 3The diagram shown is a schematic of the lifting component 3 in the lifting state.

The lifting drive mechanism 7 applies a horizontal external force to the connecting plate 31, causing the lifting assembly 3 to move horizontally along the L-shaped slide 511 until it is lifted.

[0042] In this embodiment, the lifting drive mechanism 7 can only apply force to the connecting plate 31 during the lifting operation, without setting up a structural connection; in actual use, a single lifting drive mechanism 7 can correspond to different lifting components 3 that are transferred to the loading position.

[0043] like Figure 6 As shown, the lifting drive mechanism 7 has the following structure: it includes a linear drive power 71 installed on an external working platform, a horizontal drive power 72 installed at the output end of the horizontal drive power 71, and a push block 73 installed at the output end of the horizontal drive power 72; the action of the horizontal drive power 72 causes the push block 73 to move to align with the connecting plate 31, and then the action of the linear drive power 71 applies force to the connecting plate 31 through the push block 73, causing the lifting assembly 3 to move along the L-shaped slide groove 511.

[0049] Further comprising a pressing unlocking mechanism 6, the pressing unlocking mechanism 6 pushes the active rod 42 to move upward relative to the support block 41, thereby overcoming the elastic force of the elastic body 48 to unlock the pressing of the pressing assembly 4.

[0050] In this embodiment, when the pressing action of the pressing assembly 4 needs to be unlocked, the cylinder in the pressing unlocking mechanism 6 works, pushes the active rod 42 to move upward relative to the support block 41, thereby overcoming the elastic force of the elastic body 48, driving the swing rod one 43, the adapter rod 47, the swing rod two 46 to flip upward relative to the support block 41, and the swing arm 45 to swing upward, thereby contacting the pressing of the pressing block 44.
