DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7 As shown, the present invention provides a technical solution: a shoe upper cutting device, comprising a workbench 1, a placing table 31 is arranged below the workbench 1, a cut cloth 32 is placed on the top of the placing table 31, an external lifting component is arranged below the placing table 31, the external lifting component is used to make the placing table 31 rise or fall, a leveling component is arranged on the top of the workbench 1, the leveling component is used to correct the wrinkles on the surface of the cut cloth 32, a fixing component is fixedly connected to one side of the leveling component, the fixing component is used to fix the corrected cut cloth 32, an external laser cutting component is arranged on the top of the workbench 1, the external laser cutting component is used to laser cut the cut cloth 32 to produce a shoe upper.

[0023] During operation: the existing upper cutting device needs to place the upper material on the cutting table before cutting and accurately cut it into the required shape and size. However, since the upper material is soft, it is easy to wrinkle when placed on the cutting table. The wrinkles will cause the upper material to be uneven during the cutting process, making it impossible for the cutting tool to accurately cut the material, resulting in inaccurate cutting size, affecting the quality and appearance of the final shoes. In addition, the wrinkles of the upper material will cause material displacement or cutting errors during cutting, resulting in material waste. Through the embodiment of the present scheme, during specific use, the cut shear cloth 32 is first placed directly above the placement table 31, and the placement table 31 is raised through an external lifting component until the top surface of the placement table 31 is flush with the top surface of the workbench 1, and the shear cloth 32 reaches the cutting position point, and then the wrinkles on the surface of the shear cloth 32 are corrected by starting the leveling component. After the leveling is completed, the leveling component will drive the fixing component The two ends of the cut fabric 32 are fixed to prevent the cut fabric 32 from being unstable during the cutting process, thereby preventing inaccurate cutting. Then, the surface of the cut fabric 32 is cut multiple times by an external laser cutting assembly to obtain a shoe upper. After the cutting is completed, the placement table 31 is lowered by an external lifting assembly, and then the obtained shoe upper and the remaining cut fabric 32 are collected. Through the above embodiment, the surface of the cut fabric 32 is leveled by a leveling assembly and a fixing assembly. Before cutting, the surface of the cut fabric 32 can remain flat without wrinkles or irregular parts. When cutting, the material can be more easily positioned and operated accurately, thereby improving the cutting accuracy and consistency. After leveling, the position of the cut fabric 32 is fixed so that the position of the cut fabric 32 will not shift during the cutting process, thereby preventing the cutting from deviating from the expected trajectory, resulting in failure of the shoe upper cutting and material waste.

[0024] like Figures 2 to 4 As shown, the leveling assembly includes a plurality of U-shaped inner groove seats 2, and the plurality of U-shaped inner groove seats 2 are fixedly installed on the top of the workbench 1. The inner walls of every two U-shaped inner groove seats 2 are slidably connected with a slide rod 10, and the outer walls of the two slide rods 10 are fixedly connected with a flattening shaft 9. The two flattening shafts 9 are located on the top of the sheared cloth 32 and the two flattening shafts 9 are in a fitting relationship in the initial state. A pull rope assembly is provided on one side of the two slide rods 10, and the pull rope assembly is used to drive the two slide rods 10 to slide along the inner grooves of the two groups of U-shaped inner groove seats 2.

[0025] During operation: start the pull rope assembly to move the two slide bars 10 along the inner slide groove track of the U-shaped inner groove seat 2. When the two slide bars 10 respectively drive the two flattening shafts 9 to slide from one end of the top of the U-shaped inner groove seat 2 to the other end of the top of the other side, the two flattening shafts 9 will pass through the upper surface of the shear cloth 32 and slide toward the two sides of the shear cloth 32. During the sliding process, the wrinkled parts on the surface of the shear cloth 32 will be corrected by the extension on both sides. Compared with the existing leveling toward one side, the advantage of this device is that after leveling, the overall position of the shear cloth 32 will not change, so the overall position of the reserved cutting line engraved on its surface will not change, only the wrinkled parts on its surface will be corrected and extended toward both sides. When cutting, the position of the cutting line will not change due to leveling.

[0026] like Figures 2 to 5 As shown, the pull rope assembly includes multiple pull ropes 3, each pull rope 3 is located inside the U-shaped inner groove seat 2, one end of the pull rope 3 is fixedly connected to the outer wall of the slide rod 10, the other end of the pull rope 3 is fixedly connected to a rope ring 4, the inner wall of the rope ring 4 is fixedly connected to a connecting rotating rod 6, and multiple rope shafts 5 are fixedly installed on the top of the workbench 1, the inner wall of the rope shaft 5 is rotatably connected to the outer wall of the connecting rotating rod 6, and a rope releasing assembly is provided on the top of the U-shaped inner groove seat 2 for resetting the flattening shaft 9 after cutting is completed.

[0027] During operation: when the two connecting rods 6 rotate, the rope ring 4 will be driven to rotate. When the rope ring 4 rotates, one end of the tension rope 3 will begin to wrap around the inner shaft of the rope shaft 5 and shrink. During the shrinkage process, the tension rope 3 will pull the sliding rod 10 along the inner groove of the U-shaped inner groove seat 2 through the flattening shaft 9. During the sliding process, the surface of the sheared cloth 32 can be flattened. After the flattening is completed, the flattening shaft 9 will move to the other end of the U-shaped inner groove seat 2 and remain stationary to prevent the top surface of the sheared cloth 32 from being blocked during cutting. After the cutting is completed, the connecting rod 6 is rotated in the opposite direction to make the tension rope 3 at the rope shaft 5 start to release the rope, and the flattening shaft 9 is reset through the rope releasing assembly.

[0028] like Figures 2 to 5 As shown, the rope releasing assembly includes multiple rope-looping shafts 11, and the multiple rope-looping shafts 11 are respectively fixedly installed on the top of one end of multiple U-shaped inner groove seats 2. The inner shaft diameter of the rope-looping shaft 15 is the same as the inner shaft diameter of the tension rope 12. The tension rope 12 is wound on the inner shaft of the rope-looping shaft 11, and one end of the tension rope 12 is fixedly connected to the outer wall of the sliding rod 10. One end of the inner shaft of the rope-looping shaft 11 is fixedly connected to a transmission ring 3 19, and a transmission assembly is arranged on the outside of the transmission ring 3 19. The transmission assembly is used to make the connecting rod 6 and the transmission ring 3 19 rotate simultaneously.

[0029] During operation: when the connecting rotating rod 6 rotates to contract the tension rope 3, the transmission ring 3 19 will rotate through the transmission assembly, and when the transmission ring 3 19 rotates, the tension rope 2 12 will start to be released through the inner shaft of the rope-hooking shaft 2 11. Since the built-in diameter of the rope-hooking shaft 15 is the same as the inner shaft diameter of the tension rope 2 12, the rope-collecting length of the inner shaft of the rope-hooking shaft 15 is equal to the rope-releasing length of the tension rope 2 12, which not only makes the flattening shaft 9 slide along the inner groove of the U-shaped inner groove seat 2 more stably, but also in the subsequent process, it only needs to rotate the connecting rotating rod 6 in the opposite direction, the inner shaft of the rope-hooking shaft 5 to release the rope, and the inner shaft of the rope-hooking shaft 2 11 to collect the rope, so that the positions of the sliding rod 10 and the flattening shaft 9 can be restored.

[0030] like Figure 1 and Figure 5 As shown, the transmission assembly includes a plurality of transmission rings 17, and every two transmission rings 17 are respectively fixedly mounted on the outer wall of the connecting rod 6, and a transmission belt 18 is transmission-connected between the outer wall of each transmission ring 17 and the outer wall of each transmission ring 3 19.

[0031] During operation: when the connecting rod 6 rotates, it will drive the transmission ring 2 17 to rotate, and multiple transmission rings 2 17 will drive multiple transmission rings 3 19 to rotate through each transmission belt 2 18, thereby realizing the simultaneous movement of the rope pulling assembly and the rope releasing assembly, which is convenient for the flattening shaft 9 to level and reset.

[0032] like Figure 1 and Figure 5 As shown, one end of the two connecting rotating rods 6 is fixedly connected with a transmission ring 13, a transmission belt 14 is transmission-connected between the outer walls of the two transmission rings 13, a rotating ring 15 is transmission-connected to the inner wall at the center of the transmission belt 14, and a motor 16 is fixedly connected to the top of the workbench 1, and the output shaft of the motor 16 is fixedly connected to one side of the rotating ring 15.

[0033] During operation: by starting the motor 16, the rotating ring 15 will be driven to rotate, and the rotation of the rotating ring 15 will drive the two transmission rings 13 to rotate through the transmission belt 14, and the two transmission rings 13 will drive the two connecting rotating rods 6 to rotate at the same time, thereby achieving the effect of driving the two flattening shafts 9 to slide along the inner slide groove of the corresponding U-shaped inner groove seat 2 at the same time, achieving the effect of flattening from the center of the sheared cloth 32 toward both sides.

[0034] like Figures 2 to 4 As shown, one side of the multiple U-shaped inner groove seats 2 is fixedly connected with a rope winding seat 7, and the outer wall of the rope winding seat 7 is fitted with the outer wall of the tension rope 3. The tops of the multiple U-shaped inner groove seats 2 are fixedly connected with a rope winding seat 2 8, and the outer wall of the rope winding seat 2 8 is fitted with the outer wall of the tension rope 3.

[0035] During operation: the pulling direction of the tension rope 3 is changed by the rope winding seat 1 7 and the rope winding seat 2 8, so that the tension rope 3 can always be pulled around the outer wall of the rope winding seat 1 7 and the outer wall of the rope winding seat 2 8 during the process of collecting and releasing the rope, making the tension rope 3 more stable during the pulling process.

[0036] like Figure 6 to Figure 7 As shown, the fixing assembly includes two upper plates 20, and the two upper plates 20 are respectively fixedly installed between the inner sides of each two U-shaped inner groove seats 2, and the inner wall of the upper plate 20 is inserted with an insertion rod 22 and a movable rod 28, and the bottom of the insertion rod 22 is fixedly connected with a rack plate 21, and the teeth of the rack plate 21 are meshed with a gear 25, and the outer wall of the movable rod 28 is fixedly connected with a rack plate 27, and the teeth of the rack plate 27 are meshed with the teeth of the gear 25, and the inner wall of the gear 25 is fixedly connected with a gear rod 26, and both ends of the gear rod 26 are rotatably connected to the inner wall of the U-shaped inner groove seat 2, and the bottom of the movable rod 28 is fixedly connected with a fixing part 29.

[0037] During operation: after the two flattening shafts 9 have flattened the surface of the sheared cloth 32, the flattening shaft 9 will move upward along one end of the U-shaped inner groove seat 2, and when the flattening shaft 9 moves upward, it will squeeze the rack plate 1 21 upward, and when the rack plate 1 21 moves upward, it will drive the rack plate 27 to move downward through the gear 25, and when the rack plate 27 moves downward, it will cause the fixing part 29 to move downward until it contacts the surface of the sheared cloth 32, thereby fixing the position of the sheared cloth 32 after it has been flattened, and accurately cutting the surface of the sheared cloth 32.

[0038] like Figure 6 to Figure 7 As shown, the top of the insertion rod 22 is fixedly connected to the limiting sleeve 23 , the top of the movable rod 28 is fixedly connected to the limiting block 30 , and a return spring 24 is fixedly connected between the bottom of the limiting sleeve 23 and the top of the upper plate 20 .

[0039] During operation: through the limiting sleeve 23 and the reset spring 24, when the flattening shaft 9 is reset, the rack plate 21 will also be reset, and the fixing member 29 will be driven to reset through the gear 25, so as to facilitate the removal of the cut cloth 32.

[0040] like Figure 1 As shown, fixed columns 35 are fixedly connected on both sides of the workbench 1, and the inner walls of the fixed columns 35 are provided with sliding grooves 36. The inner walls of the sliding grooves 36 are slidably connected with sliders 34 and are adapted to each other. One end of the slider 34 is fixedly connected with a connecting piece 33, and the connecting piece 33 is fixedly connected to one side of the placement table 31.

[0041] During operation: through the sliding connection between the slider 34 and the slide groove 36, and through the connection with the placement table 31 through the connecting piece 33, the placement table 31 can be more stable when it is raised or lowered by the external lifting component, and when the slider 34 moves to the top inner wall of the slide groove 36, the top surface of the placement table 31 can be just flush with the top surface of the workbench 1.

[0042] Workflow: First, place the cut fabric 32 directly above the placement table 31, and use an external lifting component to raise the placement table 31 until the top surface of the placement table 31 is flush with the top surface of the workbench 1, and the cut fabric 32 reaches the cutting position.

[0043] Then, by starting the motor 16, the rotating ring 15 will be driven to rotate, and the rotation of the rotating ring 15 will drive the two transmission rings 13 to rotate through the transmission belt 14, and the two transmission rings 13 will drive the two connecting rotating rods 6 to rotate simultaneously. When the two connecting rotating rods 6 rotate, the rope ring 4 will be driven to rotate. When the rope ring 4 rotates, one end of the tension rope 3 will begin to wrap around the inner shaft of the rope shaft 5 and shrink. During the shrinkage process, the tension rope 3 will pull the sliding rod 10 along the inner groove of the U-shaped inner groove seat 2 through the flattening shaft 9. During the sliding process, the surface of the sheared cloth 32 can be flattened. After the flattening is completed, the flattening shaft 9 will move to the other end of the U-shaped inner groove seat 2 and remain motionless to prevent the top surface of the sheared cloth 32 from being blocked during cutting. Secondly, when the two slide bars 10 move along the inner slide groove track of the U-shaped inner groove seat 2, when the two slide bars 10 respectively drive the two flattening shafts 9 to slide from one end of the top of the U-shaped inner groove seat 2 to one end of the top of the other side, the two flattening shafts 9 will pass through the upper surface of the shear cloth 32 and slide toward the two sides of the shear cloth 32. During the sliding process, the wrinkled parts appearing on the surface of the shear cloth 32 will be corrected by the extension on both sides. Through the rope winding seat 1 7 and the rope winding seat 2 8, the pulling direction of the tension rope 3 is changed, so that the tension rope 3 can always be pulled around the outer wall of the rope winding seat 1 7 and the outer wall of the rope winding seat 2 8 during the process of collecting and releasing the rope, so that the tension rope 3 is more stable during the pulling process.

[0044] When the connecting rotating rod 6 rotates to contract the tension rope 3, it will drive the transmission ring 2 17 to rotate, and the multiple transmission rings 2 17 will drive the multiple transmission rings 3 19 to rotate through the transmission belts 2 18, and when the transmission ring 3 19 rotates, the tension rope 2 12 will start to be released through the inner shaft of the rope-hooking shaft 2 11. Since the built-in diameter of the rope-hooking shaft 15 is the same as the inner shaft diameter of the tension rope 2 12, the rope-collecting length of the inner shaft of the rope-hooking shaft 15 is equal to the rope-releasing length of the tension rope 2 12, which not only makes the flattening shaft 9 slide along the inner groove of the U-shaped inner groove seat 2 more stably, but also in the subsequent process, it only needs to rotate the connecting rotating rod 6 in the opposite direction, the inner shaft of the rope-hooking shaft 5 to release the rope, and the inner shaft of the rope-hooking shaft 2 11 to collect the rope, so that the positions of the sliding rod 10 and the flattening shaft 9 can be restored.

[0045] When the two flattening shafts 9 have flattened the surface of the sheared cloth 32, the flattening shaft 9 will move upward along one end of the U-shaped inner groove seat 2, and when the flattening shaft 9 moves upward, it will squeeze the rack plate 1 21 upward, and when the rack plate 1 21 moves upward, it will drive the rack plate 27 to move downward through the gear 25, and when the rack plate 27 moves downward, it will cause the fixing part 29 to move downward until it contacts the surface of the sheared cloth 32, thereby achieving the fixing of the position of the sheared cloth 32 after it is flattened, and through the limit sleeve 23 and the reset spring 24, when the flattening shaft 9 is reset, the rack plate 1 21 will also be reset, and the fixing part 29 will be reset through the gear 25, so as to facilitate the removal of the cut sheared cloth 32.

[0046] Finally, the surface of the cut fabric 32 is cut multiple times by an external laser cutting assembly to obtain a shoe upper. After the cutting is completed, the placement table 31 is lowered by the lifting assembly, and then the obtained shoe upper and the remaining cut fabric 32 are collected.
