Movement: When the first main extrusion block 53 contacts the first auxiliary extrusion block 56, the moving plate 35 continues to move, causing the first auxiliary extrusion block 56 to extrude force against the first main extrusion block 53. At this time, the slide rod 54 slides on the placement rack 6, the first spring 55 extends, and the pressure plate 5 descends to press the leather. After pressing, the moving plate 35 continues to move, and the second main extrusion block 84 contacts the second auxiliary extrusion block 88. The moving plate 35 continues to move, and the second auxiliary extrusion block 88 extrudes force against the second main extrusion block 84. At this time, the second spring 87 shortens, causing the suction cup 7 to descend away from the leather and the ball bearing 8 to move away from the leather, causing the leather to fall onto the moving rack 82. The suction cup 7 then limits the leather's movement.

[0022] In this embodiment, as Figures 1-11 As shown in the figure, the working process of a leather edge finishing machine with positioning function provided in this embodiment is as follows: Step 1: Place the leather on the suction cup 7. The suction cup 7 positions the leather. The oiler 41 is activated to deliver oil to the oil outlet 43. The edge of the leather contacts the oil outlet 43 for edge oiling. The second motor 9 is activated to drive the support plate 75 to rotate, which in turn drives the rotating plate 71 to rotate. When the rotating plate 71 rotates, it drives the suction cup 7 to rotate, which in turn drives the leather to rotate. Step 2: After the edge painting is completed, the first motor 2 starts and drives the gear 31 to rotate. When the gear 31 rotates, it drives the rack 3 to move. When the rack 3 moves, it drives the moving plate 35 to move. When the moving plate 35 moves, it drives the placement frame 6 and the pressure plate 5 to move. When the first main extrusion block 53 contacts the first auxiliary extrusion block 56, the moving plate 35 continues to move, and then the first auxiliary extrusion block 56 extrudes the first main extrusion block 53. At this time, the slide rod 54 slides on the placement frame 6, the first spring 55 extends, and then drives the pressure plate 5 to descend and press the leather. After pressing, the moving plate 35 continues to move. When the second main extrusion block 84 comes into contact with the second auxiliary extrusion block 88, the moving plate 35 continues to move, and the second auxiliary extrusion block 88 extrudes the second main extrusion block 84. At this time, the second spring 87 shortens, which in turn drives the suction cup 7 to descend away from the leather and drives the ball bearing 8 away from the leather, causing the leather to fall onto the moving frame 82, where the suction cup 7 limits the leather. At this time, the moving plate 35 continues to move. When the first main extrusion block 53 moves to the other end of the first auxiliary extrusion block 56, the pressure plate 5 rises away from the leather, and the worker removes the leather from the placement rack 6.

[0023] In summary, in this embodiment, the leather edge finishing machine with positioning function, by setting the base frame 11, facilitates the support of the first support frame 12; by setting the support column 22 and the second support frame 21 to cooperate with each other, facilitates the support of the first motor 2; by setting the guide ring 33 and the guide rod 32 to slide and connect, facilitates the guiding and limiting of the moving plate 35; by setting the support rod 34, facilitates the support of the rack 3; by setting the first connecting column 36, facilitates the support of the moving plate 35; by setting the connecting rod 4 and the connecting plate 42, facilitates the support of the oil outlet 43; by setting the side rod 61, facilitates the support of the placement frame 6; and by setting the outer frame 91 and the fourth connecting column 92 ... slide, facilitates the support of the first motor 2; by setting the guide ring 33 and the guide rod 32 to slide, facilitates the support of the first motor 2; by setting the guide ring 33 and the guide rod 42 to slide, facilitates the support of the first motor 2; by setting the guide ring 33 and the guide rod 42 to slide, facilitates the support of the first motor 2; by setting the guide ring 33 and the guide rod 42 to slide, facilitates the support of the first motor 2; by setting the guide ring 33 and the guide rod 42 The mutual cooperation facilitates the support of the second motor 9.

The sliding connection between the moving rod 74 and the moving ring 77 facilitates the guidance and limiting of the suction cup 7. The suction cup 7 allows the leather to be placed on it, positioning it. The start of the second motor 9 drives the support plate 75 to rotate, which in turn drives the rotating plate 71 to rotate. The rotation of the rotating plate 71 drives the suction cup 7 to rotate, which in turn drives the leather to rotate. At this time, the oiler 41 starts, delivering oil to the oil outlet 43. The edge of the leather contacts the oil outlet 43 for edge oiling. The mutual cooperation between the guide plate 73 and the rotating groove facilitates movement. When the frame 82 descends, it causes the suction cup 7 to descend as well, separating the suction cup 7 from the leather. The base column 81 reduces friction during leather rotation, preventing wear. The limiting ring 85, slidably connected to the side rod 61, guides and limits the movement of the frame 82. The second connecting column 83 supports the second main extrusion block 84, and the third connecting column 89 supports the second auxiliary extrusion block 88. The sliding rod 54, slidably connected to the placement frame 6, guides and limits the pressure plate 5. The lifting rod 52 supports the first main extrusion block 53, and the lifting column 57 supports the first auxiliary extrusion block 56. The first motor 2, when started, drives the gear 31 to rotate. When the gear 31 rotates, it drives the rack 3 to move, which in turn drives the moving plate 35 to move. The moving plate 35 then drives the placement rack 6 and the pressure plate 5 to move. When the first main pressing block 53 contacts the first auxiliary pressing block 56, the moving plate 35 continues to move, causing the first auxiliary pressing block 56 to press the first main pressing block 53. At this time, the slide rod 54 slides on the placement rack 6, and the first spring 55 extends, causing the pressure plate 5 to descend and press the leather. After pressing, the moving plate 35 continues to move, at which point the second main pressing block 84 contacts the second auxiliary pressing block 88. The moving plate 35 continues to move, causing the second auxiliary pressing block 88 to press the second main pressing block 84.At this point, the second spring 87 shortens, causing the suction cup 7 to descend away from the leather and the ball bearing 8 to move away from the leather, allowing the leather to fall onto the movable frame 82. The suction cup 7 then contacts and limits the leather's movement. Meanwhile, the movable plate 35 continues to move. When the first main pressing block 53 moves to the other end of the first auxiliary pressing block 56, the pressure plate 5 rises away from the leather, making it easier to remove the leather from the placement rack 6.
