[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4, A shoe material punching cutter of the present invention includes a machine tool. There are brackets 1 on both sides of the machine tool, and a support platform 8 is arranged between the two brackets 1. One end of the bracket 1 is equipped with a controller. At both ends of the bottom of the bracket 1, feet 11 are installed. A conveying device is installed on the top of the bracket 1. A pneumatic fixture 13 is installed on the conveying device. A slide rail is arranged outside the bracket 1. The bracket 1 installs a cutting frame 3 through the slide rail. The cutting frame 3 is connected to the slide rail through a sliding cylinder. An X-direction slide rail 4 is installed at the bottom of the cutting frame 3. The X-direction slide rail 4 installs a Y-direction guiding frame 5 through a sliding cylinder. A Y-direction slide rail is installed at the bottom of the Y-direction guiding frame 5. The Y-direction slide rail installs a lifter 6 through a sliding cylinder. A cutting machine 7 is installed at the bottom of the lifter 6. Buffer blocks 31 are arranged at both ends inside the cutting frame 3, and the buffer blocks 31 are located at both ends of the X-direction slide rail 4. A rubber pad is arranged on the side of the buffer block 31. The inner cavity of the support platform 8. There are several ventilation holes 15 on the top of the support platform 8. The ventilation holes 15 are communicated with the cavity. A plurality of suction fans 14 are installed at both ends of the support platform 8. The suction fans 14 are communicated with the cavity.

[0024] When the shoe material punching cutter 7 is in use, first place the cutting sheet on the conveying device and clamp the corner of the cutting sheet by the pneumatic fixture 13. At the same time, when cutting the cutting sheet, start the suction fan 14 to cooperate with the cavity and the ventilation holes 15 to discharge the air flow introduced into the cavity through the ventilation holes 15, so as to adsorb the cutting sheet and prevent the cutting sheet from shifting during the cutting of the cutting sheet. When the cutter 7 finishes cutting the cutting sheet, the conveying device conveys the cutting sheet to the next station, and the cutting sheet is removed manually. Then, control the conveying device to reset for processing the next cutting sheet. The driving motor 21 of the conveying device, the pneumatic fixture 13, the sliding cylinder, the hydraulic press 9, the lifter 6 and the cutter 7 are all controlled by the controller. The controller is a PLC controller, which is a commonly used technical means in the numerical control program. The cutter 7 can be a conventional cutting structure in the shoe material cutting field and is not specifically limited. The cutter 7 of the present invention preferably integrates cutting, drawing lines, punching V-shaped holes and punching circular holes on the same cutter head to complete the multi-process punching of shoe materials. When cutting, a buffer block 31 is added to prevent the cutter head from being damaged due to impact. When cutting, the height of the cutter 7 is adjusted by the lifter 6 to cut the cutting sheet. At the same time, the cutter 7 and the lifter 6 move in the Y direction on the Y-direction guide frame 5 through the sliding cylinder, and the Y-direction guide frame 5 moves in the X direction on the X-direction guide rail through the sliding cylinder, so that the cutter 7 moves in the X direction, so that the cutter 7 can conveniently perform special-shaped cutting on the cutting sheet. The cutting frame 3 moves on the slide rails on both sides of the bracket 1 through the sliding cylinder to adjust the position of the cutting frame 3 to cut at different positions of the cutting sheet, and process the whole cutting sheet, avoiding frequent movement of the cutting sheet and causing the cutting sheet to shift, which affects the subsequent cutting process. The model of the lifter 6 in the present invention is not specifically limited, as long as it can assist the cutter 7 to lift and adjust the height. The lifter 6 can be a conventional structure in the lifting device field.

[0025] In order to improve the safety of the cutting sheet, in this embodiment, the bracket 1 and the support platform 8 are of a split structure, the side of the support platform 8 is a chamfered structure, and the two ends of the bottom of the support platform 8 are provided with support frames 10. The chamfer design avoids scratching the cutting sheet when adsorbing or moving the cutting sheet.

[0026] In order to facilitate the adjustment of the height of the bracket 1 and the support platform 8, in this embodiment, the feet 11 and the support frames 10 are hydraulic lifting rods, and a hydraulic press 9 is installed on the bracket 1 and the support platform 8 and connected to the hydraulic lifting rods. The height of the feet 11 and the support frames 10 is adjusted by the hydraulic press 9, so that the support platform 8 is horizontal with the pneumatic fixture 13, facilitating the cutting sheet to be laid flat on the support platform 8, so that the cutting sheet is supported by the support platform 8 when being cut, preventing the cutting sheet from being too soft and affecting the cutting effect.

[0027] In order to facilitate the conveyance of the cut sheet material, in this embodiment, the conveying device includes a driving motor 21, a transmission shaft, a conveyor chain, and a conveying frame. The conveying frame includes a first conveying frame 12 and a second conveying frame 2. The transmission shaft includes a first transmission shaft 22 and a second transmission shaft 23. The first transmission shaft 22 is installed at both ends of the first conveying frame 12, and the second transmission shaft 23 is installed at both ends of the second conveying frame 2. Transmission gears 29 are provided on both the first transmission shaft 22 and the second transmission shaft 23. The conveyor chain meshes with the transmission gears 29 on the first transmission shaft 22 and the second transmission shaft 23. The starting fixture is installed on the conveyor chain. The driving motor 21 is installed at both ends of the first conveying frame 12 and is connected to the first transmission shaft 22 through a coupling. The other end of the first transmission shaft 22 is connected to the second transmission shaft 23 through a transmission rod 24. By providing two conveying frames, both ends of the cut sheet material are fixed by the fixture, thereby facilitating the cutting of the cut sheet material and preventing the cut sheet material from shifting during the cutting operation. When the cutting machine 7 finishes cutting the cut sheet material, the driving motor 21 drives the first transmission shaft 22 and the second transmission shaft 23 to drive the conveyor chain to move and convey the cut sheet material to the next process for recycling the remaining cut sheet material after cutting. Then, the driving motor 21 controls the first transmission shaft 22 and the second transmission shaft 23 to rotate in the reverse direction, thereby resetting the conveyor belt. The first transmission shaft 22 and the second transmission shaft 23 are linked through the transmission rod 24, so as to ensure that the rotation speeds of the first transmission shaft 22 and the second transmission shaft 23 are at the same rate, improving the stability of the conveying mechanism in this embodiment. The structure of the conveying device of the present invention is not specifically limited, and only the reciprocating movement of the pneumatic fixture 13 needs to be controlled. This embodiment is the preferred solution of the conveying device of the present invention.

[0028] In order to improve the stability of the pneumatic fixture 13, in this embodiment, the pneumatic fixture 13 includes a base. The base is of a U-shaped structure. A pneumatic cylinder 25 is provided at the top of the open end of the base. A lower clamping block 28 is installed at the lower end of the open end of the base through a chute. A connecting block 26 is provided inside the open end of the base. An upper clamping block 27 is installed on the connecting block 26 through a chute. The pneumatic cylinder 25 is connected to the connecting block 26 through a telescopic rod. By controlling the pneumatic action of the pneumatic cylinder 25 to control the telescopic movement of the telescopic rod, the cut sheet material is clamped by the cooperation of the upper clamping block 27 and the lower clamping block 28. And buffer rubber pads are arranged on both the upper clamping block 27 and the lower clamping block 28 to avoid scratching the cut sheet material. The structure of the pneumatic fixture 13 in the present invention is not specifically limited, and a conventional pneumatic fixture 13 on the market can be used. The structure of the pneumatic fixture 13 in this embodiment is the preferred solution of the present invention.

[0029] For the convenience of moving this device, in this embodiment, stabilizing seats 18 are installed at the bottoms of the feet 11 and the support frame 10. An installation groove is provided at the bottom of the stabilizing seat 18, and a pulley 19 is installed in the installation groove. The pulley 19 is connected to the installation groove through a threaded rod 20. Handles 30 are installed at both ends of the support platform 8 and on both sides of the support 1. When moving this device, the support 1 or the support platform 8 can be lifted through the handles 30, and then the pulley 19 is installed on the stabilizing seat 18.

[0030] To improve the sliding stability of the cutting frame 3, in this embodiment, the slide rails on the outside of the support 1 include a main slide rail 16 and a secondary slide rail 17. The secondary slide rail 17 is located on both sides of the main slide rail 16. The cutting frame 3 is connected to the main slide rail 16 through a sliding cylinder, and the cutting frame 3 is connected to the secondary slide rail 17 through a lead screw. Since there are many components installed on the cutting frame 3, the cooperation of the main slide rail 16 and the secondary slide rail 17 improves the support performance for the cutting frame 3, thereby ensuring the stability when the cutting frame 3 slides.

[0031] To improve the adsorption force, in this embodiment, a plurality of cavities are provided in the cavity of the support platform 8, and the suction fan 14 corresponds to each cavity. By providing separate cavities corresponding to the ventilation holes 15, the air flow directly communicates with the ventilation holes 15 when the suction fan 14 is started, avoiding the dispersion of the air flow in the cavity, thereby improving the adsorption force.
