[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, an automatic shoe upper cutting machine includes a conveyor belt 2. A support platform 5 is fixedly connected to the bottom of one end of the conveyor belt 2. First guide rollers 3 are installed on the top of both ends of the conveyor belt 2. An electric unwinding roller 4 is installed at the end of the conveyor belt 2 away from the support platform 5. An "L"-shaped bracket 7, a clamping roller 10, a second guide roller 9 and an electric winding roller 6 are installed sequentially from left to right on the top surface of the support platform 5. An ejection mechanism 8 is installed on the bottom surface of the top plate of the "L"-shaped bracket 7. A collection box 11 is provided on the support platform 5. The collection box 11 is located directly below the ejection mechanism 8.

[0022] In this embodiment, the ejection mechanism 8 includes a base plate 85, an electric cylinder 81, a slide groove 83, and a slider 82. Two electric cylinders 81 are fixedly installed on the bottom surface of the top plate of the "L"-shaped bracket 7. The base plate 85 is fixedly installed at the bottom telescopic end of the two electric cylinders 81. The bottom of the base plate 85 is provided with a slide groove 83. Several sliders 82 are slidably installed on the slide groove 83. Fixing screws 84 are threaded through the sliders 82. Three ejection columns 86 are fixedly installed at the bottom of the sliders 82.

[0023] Specifically, by setting the electric cylinder 81 to push downwards, the unseparated shoe upper slices in the cut shoe upper material 17 can be pushed out and fall into the collection box 11. The cut and separated shoe upper slices will roll into the collection box 11 as the conveyor belt 2 is opened, making it convenient to take out and use later and reducing manual operation.

[0024] In this embodiment, several support legs 1 are installed at the bottom of the conveyor belt 2 and the support platform 5; the bottom surface of the collection box 11 is an inclined surface, and a discharge port 12 is provided on one side wall of the collection box 11 near the bottom of the inclined surface; shoe upper fabric 17 is installed on the electric unwinding roller 4, two first guide rollers 3, clamping roller 10, second guide roller 9 and electric winding roller 6; a first linear motor assembly 13 is installed on both sides of the conveyor belt 2, a second linear motor assembly 14 is installed on the moving end of the two first linear motor assemblies 13, a third linear motor assembly 15 is installed on the moving end of the second linear motor assembly 14, and a cutting assembly 16 is installed on the moving end of the third linear motor assembly 15.

[0025] Specifically, by controlling the electric unwinding roller 4 to unwind the shoe upper fabric 17 and the electric take-up roller 6 to take up the waste material after cutting, there is no need for manual collection and laying, realizing streamlined shoe upper cutting, which is convenient to operate and has high cutting efficiency.

[0026] Working principle: All electrical components in this invention are externally connected to a power supply and control switch during use. A protective layer is attached to the surface of the conveyor belt 2 to protect it from the cutting effect of the cutting assembly 16. The shoe upper fabric 17 is mounted on the electric unwinding roller 4. The shoe upper fabric 17 passes sequentially through two first guide rollers 3, then through the clamping roller 10, the second guide roller 9, and the electric winding roller 6. The three ejector posts 86 are positioned to match the cut shoe upper, and can eject the cut shoe upper downwards. The first linear motor assembly 13, the second linear motor assembly 14, and the third linear motor assembly 1... The 5 and the cutting component 16 work together to cut the shoe upper material 17 at the bottom. This is the existing technology. By controlling the electric unwinding roller 4 to unwind the shoe upper material 17 and the electric winding roller 6 to wind up the waste material after cutting, no manual collection and laying is required, realizing streamlined shoe upper cutting. The operation is convenient and the cutting efficiency is high. By setting the electric cylinder 81 to push downward, the shoe upper slices that have not been separated from the cut shoe upper material 17 can be pushed out and fall into the collection box 11. The shoe upper slices that have been separated will roll into the collection box 11 as the conveyor belt 2 is opened, which is convenient for subsequent removal and use and reduces manual operation.
