[0002] EVA sole is a sole material made of ethylene-vinyl acetate copolymer (Ethylene-Vinyl Acetate), which has the advantages of lightness, good elasticity, high flexibility, and wrinkle resistance. The advantages of this material also include good shockproof and cushioning properties, as well as the ability to maintain certain flexibility and thermal insulation properties in low temperature environments. EVA sole punching is a process of processing EVA materials into soles through a specific process flow. In the existing EVA sole punching, large pieces of processed materials are mostly pre-cut into small pieces, and then the small pieces of materials are manually fed into the punching machine. The punched soles are then manually removed, which has high labor intensity and low work efficiency. The scraps after punching are accumulated in the work area and scattered everywhere, which hinders production and is not conducive to recycling. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 2As shown, a high-efficiency EVA sole punching machine includes a feeding area 1, a processing area 2, and a finishing area 3, wherein the feeding area 1, the processing area 2, and the finishing area 3 are arranged in sequence from left to right;

[0023] The loading area 1 is a roller conveyor, and the processing area 2 includes a carrying plate 21 and a punching head 23. The carrying plate 21 is provided with a first gantry 221, a roller 26, a second gantry 222, and a through slot 27 from left to right. The punching head 23 is provided on the first gantry 221, and a fixed cylinder 241 and a separation device 25 are fixedly provided on the second gantry 222. The through slot 27 is correspondingly provided below the separation device 25.

[0024] The sorting area 3 includes a conveyor belt 29 disposed below the carrying plate 21 . A first box 30 is disposed at the discharge end of the conveyor belt 29 . A second box 30 is disposed on the right side of the carrying plate 21 .

[0025] In this embodiment, when in use, the loading area 1 delivers the EVA sheet to be processed into the processing area 2. The EVA sheet to be processed first passes through the first gantry 221. At this time, the loading area 1 stops conveying, and the punching head 23 rises and resets after punching the EVA sheet to be processed. Then the loading area 1 resumes loading, and the unprocessed EVA sheet arrives under the punching head 23 and repeats the above processing method to punch the EVA sheet to be processed.

[0026] The existing EVA sole punching method is to divide the large piece of material to be punched into small pieces, put them into the punching machine manually, and then manually separate them after punching, which not only causes material waste but also has low processing efficiency.

[0027] like Figure 3-Figure 5 As shown, the punched EVA sheet enters under the second gantry 222 under the action of the loading area 1 and the roller 26. The second gantry 222 is provided with a plurality of through grooves 27 penetrating the bottom plate at the position corresponding to the bearing plate 21. The size of the through grooves 27 is slightly larger than the processed sole so that the sole can pass through the through grooves 27.

[0028] The second gantry 222 is provided with a fixed cylinder 241 for fixing the EVA plate, and a separation device 25 for separating the shoe mold from the plate, the separation device 25 includes a separation cylinder 251, the separation cylinder 251 is fixedly arranged in the center of the crossbeam of the second gantry 222, the piston rod end of the separation cylinder 251 is fixedly connected to the guide rail 252, and a plurality of separation blocks 253 are movably arranged on the guide rail 252, the guide rail 252 has an I-shaped cross-section, one side of the separation block 253 is slidably connected to the guide rail 252, and the other side is provided with a bolt hole, and is fixed to the guide rail 252 by bolts, the fixed cylinder 241 is arranged on the left and right of the separation cylinder 251, close to the column of the second gantry 222, and when the telescopic rod of the fixed cylinder 241 is extended, it falls on the outside of the through groove area.

[0029] In this embodiment, the EVA sheet after punching reaches the bottom of the second gantry 222, and the sole overlaps with the through groove 27. At this time, the telescopic rod of the fixed cylinder 241 descends, and the edge of the EVA sheet is pressed against the bearing plate 21 to prevent the sheet from being offset when it is separated from the sole. The telescopic rod of the separation cylinder 251 descends, driving the separation block 253 set on the guide rail 252 to push the sole out of the through groove, thereby achieving the technical effect of separating the sole from the EVA sheet. Subsequently, the fixed cylinder 241 and the separation device 25 rise and reset, and the loading area 1 and the roller 26 are started to push the EVA sheet to the right. After the sole overlaps with the through groove 27, the loading area 1 and the roller 26 stop, and the above separation action is repeated. The separation block 253 can be increased or decreased on the guide rail 252 as needed to adjust the spacing and flexibly cooperate with specific production.

[0030] like Figure 2 As shown, the processing area also includes an auxiliary rod 28, and the surface of the auxiliary rod 28 is provided with an anti-slip protrusion 281. The right end of the front and rear side walls of the supporting plate 21 is provided with an extension plate 211, and a through hole is provided on the extension plate 211. A rotating bearing 212 is arranged in the through hole. Both ends of the auxiliary rod 28 are arranged in the rotating bearing 212, and one end is fixedly connected to the drive shaft of the motor 282.

[0031] In this embodiment, the EVA sheet waste separated from the soles will be twisted, warped, and entangled with each other. The auxiliary rod 28 is driven by the motor 282 to send the EVA sheet waste into the sorting area. The anti-slip protrusions 281 are set to improve the sorting efficiency and reduce the problem of normal production being affected by the EVA sheet waste problem.

[0032] The sorting area 3 includes a conveyor belt 29, a first box 30, and a second box 31. The conveyor belt 29 is arranged below the through groove 27 to send the separated soles into the first box 30. The second box 31 contains EVA sheet waste and is movably arranged below the auxiliary rod 28. The first box 30 and the second box 31 are both provided with universal wheels to facilitate movement and improve replacement efficiency.

[0033] In this embodiment, by setting up a sorting area, the labor intensity of manually taking out the soles and cleaning the EVA sheet waste is reduced. It is only necessary to replace the boxes when the first box 30 and the second box 31 are full, thereby improving labor efficiency.

[0034] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
