[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7 This utility model is an automated leather cutting device, including a cutting table 1; two fixing plates 2 are symmetrically fixed on the surface of the cutting table 1; a guide rail 3 is provided through the side of the fixing plate 2; the tops of the two guide rails 3 are close to each other and gradually move away from each other from top to bottom; a guide shaft 4 is slidably arranged on the inner wall of the guide rail 3; a connecting block 5 is fixed to one end of the guide shaft 4; and a limiting block 6 is fixed to the other end; a connecting plate 7 is fixed to the side of the connecting block 5; a limiting groove 8 is opened on the bottom surface of the connecting plate 7; a sliding plate 9 is slidably arranged on the inner wall of the limiting groove 8; a flat plate 10 is fixed on the bottom surface of the sliding plate 9; and a number of springs 11 are evenly connected between the sliding plate 9 and the inner wall of the limiting groove 8.

[0028] Specifically, the cutting table 1 includes two symmetrically arranged mounting plates 12; a connecting rod 13 is fixed to the side of one mounting plate 12; a vertical plate 14 is fixed to one end of the connecting rod 13; two support legs are symmetrically fixed to the bottom surface of the mounting plate 12; and two conveying components are symmetrically rotatably arranged between the two mounting plates 12.

[0029] Furthermore, the conveying assembly includes an upper conveying roller 15 and a lower conveying roller 16 rotatably disposed between two mounting plates 12; one end of the upper conveying roller 15 is fixed with an upper fixed shaft 17, which passes through the mounting plate 12 and the vertical plate 14 and is fixed with an upper sprocket 18; one end of the lower conveying roller 16 is fixed with a lower fixed shaft 19, which passes through the mounting plate 12 and the vertical plate 14 and is fixed with a lower sprocket 20.

[0030] Furthermore, adjusting sprockets 21 are rotatably mounted on the side of the vertical plate 14 below the two lower sprockets 20; a chain 22 is arranged between each upper sprocket 18, lower sprocket 20, and adjusting sprocket 21; the two upper sprockets 18 rotate in the same direction; the two lower sprockets 20 rotate in the same direction; each upper sprocket 18 and adjusting sprocket 21 engages with the inner surface of the chain 22; the lower sprocket 20 engages with the outer surface of the chain 22; the upper sprockets 18 and lower sprockets 20 rotate in opposite directions.

[0031] The operation process of this embodiment is as follows: the two guide rails 3 are combined together to resemble an "eight", including a downward inclined section and a horizontal section connected to the bottom of the inclined section. In the initial state, the guide shaft 4 is located at the top of the guide rail 3, and the two connecting plates 7 are close to each other.

[0032] Then, an adjusting sprocket 21 is driven to rotate, which in turn drives the chain 22 to move. Each upper sprocket 18 and the adjusting sprocket 21 mesh with the inner surface of the chain 22, and the lower sprocket 20 meshes with the outer surface of the chain 22, so that the upper sprocket 18 and the lower sprocket 20 rotate in the same direction, which in turn makes the upper conveying roller 15 and the lower conveying roller 16 rotate in opposite directions, so that the leather can be transported smoothly.

[0033] A cutting device is slidably mounted on the fixed plate 2. The cutting device includes an electric telescopic rod and a cutting mold. The part of the leather to be cut is moved to the bottom of the cutting device by the conveying component. Then, the guide shaft 4 is driven to slide down along the guide rail 3, so that the two connecting plates 7 slide away from each other. First, the flat plate 10 is attached to the surface of the leather. Then, the connecting plate 7 continues to move down. At this time, the slide plate 9 slides inward along the inner wall of the limiting groove 8 and compresses the spring 11. When the guide shaft 4 moves to the part where the inclined section and the horizontal section are connected, the guide shaft 4 begins to slide into the horizontal section, driving the connecting plate 7 to move horizontally. This drives the flat plate 10 to slide to both sides along the surface of the leather to flatten it, realizing the automatic flattening of the leather. Then, the telescopic end of the electric telescopic rod is driven to extend downward to drive the cutting mold to cut the leather.

[0034] In this embodiment, by driving the guide shaft 4 to slide downward on the inner wall of the inclined section of the guide rail 3, the laying plate 10 first contacts the leather surface, and then drives the slide plate 9 to slide inward along the inner wall of the limiting groove 8 to compress the spring 11. When the guide shaft 4 slides on the inner wall of the horizontal section of the guide rail 3, it drives the laying plate 10 to move horizontally outward, laying the leather flat, thus realizing the automatic laying of the leather.

[0035] For a specific embodiment two, please refer to Figure 1-7Based on the first specific embodiment, a mounting block 23 is fixed to the side of the vertical plate 14; a reciprocating screw 24 is rotatably provided on the surface of the mounting block 23; a limiting shaft 25 is fixed to the surface of the mounting block 23; a movable frame 26 is provided on the periphery of the reciprocating screw 24 and slides through and engages with the limiting shaft 25; a base plate 27 is fixed to the bottom surface of the movable frame 26; a T-shaped groove 28 is provided on the bottom surface of the base plate 27; and a T-shaped slider 29 is fixed to the surface of the connecting block 5 and slides through and engages with the T-shaped groove 28.

[0036] Specifically, a first pulley 30 is rotatably mounted on the side of the vertical plate 14; a second pulley 31 is fixed to the side of an upper fixed shaft 17; and a belt 32 is provided for transmission between the first pulley 30 and the second pulley 31.

[0037] Furthermore, bevel gears 33 that mesh with each other are fixed to the side of the reciprocating screw 24 near the bottom and the side of the first pulley 30, respectively; a servo motor 34 is fixed to the bottom surface of the mounting block 23; the output end of the servo motor 34 is fixedly connected to the reciprocating screw 24.

[0038] The operation process of this embodiment is as follows: The cutting device is fixed on the side of the moving frame 26. In the initial state, the moving frame 26 is located at the top of the reciprocating lead screw 24. First, the servo motor 34 is started to drive the reciprocating lead screw 24 to rotate. A sliding hole is opened through the surface of the moving frame 26. A moving block is provided on the inner wall of the sliding hole to slide with the thread groove of the reciprocating lead screw 24. Then, the reciprocating lead screw 24 rotates and drives the moving block to slide, which in turn drives the moving frame 26 to slide down along the limiting shaft 25, which in turn drives the cutting device to move down.

[0039] Meanwhile, the reciprocating screw 24 drives the corresponding bevel gear 33 to rotate, which in turn drives another bevel gear 33 to rotate, which in turn drives the corresponding first pulley 30 to rotate, which in turn drives the second pulley 31 to rotate via the belt 32, which in turn drives the corresponding upper fixed shaft 17 to rotate, which in turn drives the corresponding upper sprocket 18 and upper conveyor roller 15 to rotate. The upper sprocket 18 drives the chain 22 to move, and all the upper sprockets 18, lower sprockets 20 and adjusting sprockets 21 are driven to rotate by the chain 22. As a result, all the upper conveyor rollers 15 and lower conveyor rollers 16 rotate to convey leather. In addition, as the moving frame 26 moves downward, it drives the T-shaped slide 28 to move downward, which in turn drives the T-shaped slider 29 to move along it, which in turn drives the guide shaft 4 to move downward along the guide rail 3 to flatten the leather. When the guide shaft 4 moves to the outermost end of the horizontal section, the servo motor 34 is turned off, and then the electric telescopic rod is driven to extend downward, which drives the cutting mold to cut the leather. Then the electric telescopic rod retracts, which drives the cutting mold to retract.

[0040] Then, the servo motor 34 is started to drive the reciprocating screw 24 to rotate. At this time, the reciprocating screw 24 drives the moving frame 26 to move upward, which in turn drives the cutting device to move upward, which in turn drives the base plate 27 to move upward, which in turn drives the T-shaped slide 28 to move upward, which in turn drives the T-shaped slider 29 to move upward, which in turn drives the guide shaft 4 to slide back along the inner wall of the guide rail 3, which in turn drives the connecting block 5, connecting plate 7, slide plate 9 and laying plate 10 to move upward. The spring 11 returns to its original position. At the same time, the reciprocating screw 24 drives the upper conveying roller 15 and the lower conveying roller 16 to rotate through a series of linkages to transport the leather. When the moving frame 26 moves to the top of the reciprocating screw 24, the above operation is repeated to carry out the next round of cutting.

[0041] In this embodiment, a servo motor 34 drives the reciprocating screw 24 to rotate, which in turn drives the moving frame 26 to move up and down. At the same time, a series of linkages drive the upper conveying roller 15 and the lower conveying roller 16 to convey leather. The guide shaft 4 is driven by the bottom plate 27 on the bottom surface of the moving frame 26 to slide along the inner wall of the guide rail 3 through a series of linkages, which saves costs.
