[0042] The second punching head 14 is rotatably disposed in the cutter head base 10 .

[0043] The second driving mechanism is disposed in the cutter head base 10 and is used for driving the second punching head 14 to rise and fall.

[0046] Preferably, when the second trigger switch 32 is triggered, the first control box 23 controls the first air inlet pipe 22 to be connected with the second air inlet hole, so that the gas input through the first air inlet pipe 22 enters the second air inlet hole to drive the second piston 31 to descend to drive the second punching head 14 to descend, and the punching operation can be performed at this time; when the second trigger switch 32 is not triggered, the first control box 23 controls the first air inlet pipe 22 to be connected with the second air outlet hole, so that the gas input through the first air inlet pipe 22 enters the second air outlet hole to drive the second piston 31 to rise to drive the second punching head 14 to rise.

[0047] The third punching head 15 is rotatably disposed in the cutter head base 10 .

[0048] The third driving mechanism is disposed in the cutter head base 10 and is used for driving the third punching head 15 to move up and down.

[0049] In this embodiment, a third through hole 103 is provided in the cutter head base 10, and a third air inlet hole and a third air outlet hole connected with the third through hole 103 are provided in the cutter head base 10, wherein the third driving mechanism includes a third piston 41, a second air inlet pipe 42, a second control box 43 and a third trigger switch 44, the third piston 41 can be raised and lowered in the third through hole 103 and is connected to the third punching head 15, the second air inlet pipe 42 is connected with the third air inlet hole and the third air outlet through the second control box 43, and the third trigger switch 44 is arranged outside the second control box 43, and is used for controlling the connection and disconnection of the second air inlet pipe 42 and the third air inlet hole and the third air outlet.

[0050] Preferably, when the third trigger switch 44 is triggered, the second control box 43 controls the second air inlet pipe 42 to be connected with the third air inlet hole, so that the gas input through the second air inlet pipe 42 enters the third air inlet hole to drive the third piston 41 to descend, thereby driving the third punching head 15 to descend, and the punching operation can be performed at this time; when the third trigger switch 44 is not triggered, the second control box 43 controls the second air inlet pipe 42 to be connected with the third air outlet hole, so that the gas input through the second air inlet pipe 42 enters the third air outlet hole to drive the third piston 41 to rise, thereby driving the third punching head 15 to rise.

[0051] The fourth punching head 16 is rotatably disposed in the cutter head base 10 .

[0052] The fourth driving mechanism is disposed in the cutter head base 10 and is used for driving the fourth punching head 16 to rise and fall.

[0053] In this embodiment, a fourth through hole 104 is provided in the cutter head base 10, and a fourth air inlet hole and a fourth air outlet hole connected to the fourth through hole 104 are provided in the cutter head base 10, wherein the fourth driving mechanism includes a fourth piston 51 and a fourth trigger switch 52, the fourth piston 51 can be raised and lowered in the fourth through hole 104 and is connected to the fourth punching head 16, the second air inlet pipe 42 is connected to the fourth air inlet hole and the fourth air outlet through the second control box 43, and the fourth trigger switch 52 is arranged outside the second control box 43, and is used to control the connection and disconnection of the second air inlet pipe 42 and the fourth air inlet hole and the fourth air outlet.

[0054] That is to say, the gas input from the second air inlet pipe 42 can enter the third air inlet hole or the third air outlet hole, and can also enter the fourth air inlet hole or the fourth air outlet hole.

[0055] Preferably, when the fourth trigger switch 52 is triggered, the second control box 43 controls the second air inlet pipe 42 to be connected with the fourth air inlet hole, so that the gas input through the second air inlet pipe 42 enters the fourth air inlet hole to drive the fourth piston 51 to descend to drive the fourth punching head 16 to descend, and the punching operation can be performed at this time; when the fourth trigger switch 52 is not triggered, the second control box 43 controls the second air inlet pipe 42 to be connected with the fourth air outlet hole, so that the gas input through the second air inlet pipe 42 enters the fourth air outlet hole to drive the fourth piston 51 to rise to drive the fourth punching head 16 to rise.

[0056] In this embodiment, the sizes of the punches of the first punching head 13, the second punching head 14, the third punching head 15 and the fourth punching head 16 are all different. It should be understood that since the sizes of the punches of the first punching head 13, the second punching head 14, the third punching head 15 and the fourth punching head 16 are all different, punches of different types can be used for punching as needed, which is highly flexible and does not require replacement operations, effectively ensuring work efficiency.

[0057] In this embodiment, a second drive motor 17 is provided in the cutter head base 10, and a third synchronous wheel 171 is provided on the rotating shaft of the second drive motor 17, wherein the outer walls of the first punching head 13, the second punching head 14, the third punching head 15 and the fourth punching head 16 are all provided with fourth synchronous wheels, and a second synchronous belt 172 is provided around the third synchronous wheel 171 and the fourth synchronous wheel, so that the third synchronous wheel 171 can be driven to rotate by the second drive motor 17, so as to drive the second synchronous belt 172 to rotate, thereby driving the fourth synchronous wheel to rotate, so as to realize the simultaneous rotation of the first punching head 13, the second punching head 14, the third punching head 15 and the fourth punching head 16, so as to realize the rotation of the first punching head 13, the second punching head 14, the third punching head 15 and the fourth punching head 16 for punching.

[0058] It should be understood that the second drive motor 17 drives the first punching head 13, the second punching head 14, the third punching head 15 and the fourth punching head 16 to rotate at the same time. When punching is actually needed, only when the punching head descends can it play a real punching role. Although the punching head that has not descended is also rotating, it will not have a punching effect.

[0059] Furthermore, the multi-punching cutting head also includes a mounting plate 18 , a third driving motor 19 and a first screw rod 20 .

[0060] A supporting plate 181 is extended from the top of the mounting plate 18, wherein a first slide rail 182 is provided on one side of the mounting plate 18, a first slider 183 is slidably provided in the first slide rail 182, the third drive motor 19 is provided in the supporting plate 181, and one end of the first screw rod 20 is connected to the rotating shaft of the third drive motor 19 so as to drive the first screw rod 20 to rotate through the third drive motor 19.

[0061] Preferably, a protrusion 100 is extended from one side end of the cutter head base 10, and the protrusion 100 is provided with a first threaded hole, wherein the first screw rod 20 is threadedly connected to the first threaded hole of the protrusion 100, and the first slider 183 is fixedly connected to the cutter head base 10, so that when the third drive motor 19 drives the first screw rod 20 to rotate, the cutter head base 10 will slide along the first slide rail 182 to adjust the height of the entire cutter head base 10.

[0062] like Figures 8 to 10As shown, a clamping structure is installed at the bottom end of the cutter head base 10, and the clamping structure includes a punching head protection seat 131 installed at the bottom end of the cutter head base 10, and the punching head protection seat 131 is arranged below the first punching head 13, and a protection frame 211 is installed at the bottom end of the first piston 21, and a guide groove 132 is provided on the side of the punching head protection seat 131 close to the protection frame 211, and a guide roller 212 is rotatably connected to one side of the top of the protection frame 211, and the guide roller 212 is slidably connected to the inside of the guide groove 132, and a pressing ring 213 is fixed to the bottom end of the protection frame 211, and the bottom end of the first punching head 13 is arranged in the middle of the pressing ring 213, and the bottom end of the pressing ring 213 is on the same horizontal line as the bottom end of the first punching head 13, and a clamping structure is also installed at the bottom end of the cutter head base 10 located at the second punching head 14, the third punching head 15 and the fourth punching head 16;

[0063] When the first piston 21 drives the first punching head 13 to move downward to perform punching, the bottom end of the first piston 21 will simultaneously drive the protective frame 211 to move downward. At this time, the protective frame 211 drives the pressure ring 213 to move downward. During this process, the guide roller 212 moves inside the guide groove 132 to guide the protective frame 211. The pressure ring 213 and the first punching head 13 descend synchronously. When the guide roller 212 contacts the surface of the cloth, it will flatten the outer area of ​​the cloth where the hole needs to be punched. At this time, the first punching head 13 punches the cloth inside the pressure ring 213, which can prevent the cloth from being deformed due to rotation during the punching process of the first punching head 13, thereby affecting the quality of the punching, and achieving a better punching effect.

[0064] like Figures 8 to 11As shown, a telescopic hole 64 is provided inside the protective frame 211, and lifting guide grooves 642 are provided on both sides inside the telescopic hole 64, and a turning guide groove 641 is provided at the bottom end of the lifting guide groove 642. A support frame 62 is provided below the protective frame 211, and an air nozzle 63 is installed at one end of the support frame 62 close to the pressure ring 213, and a rotating shaft is fixed at one end of the support frame 62 away from the air nozzle 63, and protrusions 621 are fixed on both sides of the top of the rotating shaft, and the protrusion 621 is slidably connected to the inside of the turning guide groove 641, and a spring 643 is provided at the top of the rotating shaft, and the spring 643 is provided inside the telescopic hole 64, and a pull rope 65 runs through the inside of the spring 643, and the bottom end of the pull rope 65 is fixedly connected to the top end of the rotating shaft of the support frame 62, and a support seat 651 is provided above the pull rope 65. The top of the support seat 651 is fixedly connected to the bottom of the cutter head base 10, and the support seat 651 is internally rotatably connected with a reel 653, the top of the pull rope 65 is wound around the outside of the reel 653, and coil springs 652 are fixed to the outside of both ends of the reel 653, and the other end of the coil spring 652 is fixedly connected to the support seat 651, and a hose 661 is fixed to the bottom end of the air nozzle 63, and an air guide tube 66 is fixed to the other end of the hose 661, and the other end of the air guide tube 66 is connected to the first air inlet hole of the first through hole 101. Four groups of air guide tubes 66 are provided, and the remaining three groups of air guide tubes 66 are respectively connected to the second air inlet hole of the second through hole 102, the third air inlet hole of the third through hole 103, and the fourth air inlet hole of the fourth through hole 104, and a discharge hole is provided inside the first punching head 13;

[0065] During the punching process, the portion of the cloth cut off by the first punching head 13 will be discharged to the outside through its discharge hole, but the cut cloth is easily stuck inside the discharge hole, and the accumulation of cloth in the discharge hole will affect the subsequent punching of the first punching head 13. In the initial state, the support frame 62 is located directly below the protective frame 211. During the descent of the protective frame 211, the pull rope 65 will be pulled, and the support seat 651 will remain fixed to the bottom end of the cutter head base 10. At this time, because the elastic force of the spring 643 is greater than the elastic force of the two coil springs 652, the pull rope 65 will drive the take-up shaft 653 to rotate for unwinding. When the protective frame 211 moves to a certain distance, the pull rope 65 outside the take-up shaft 653 is When the roll is fully unwound, the reel 653 will pull the drawstring 65 in the opposite direction, and the drawstring 65 will pull the support frame 62. Under the action of the protrusion 621 at the end of the shaft of the support frame 62 and the steering guide groove 641, the support frame 62 will rotate 90° clockwise. Then the protrusion 621 slides into the interior of the lifting guide groove 642. At this time, the shaft of the support frame 62 extends into the interior of the telescopic hole 64, and the spring 643 is squeezed. When the shaft of the support frame 62 is stored, the pressure ring 213 and the first punching head 13 are lowered to the position of contacting the cloth. In this process, the support frame 62 drives the air nozzle 63 away from the bottom of the pressure ring 213 to prevent the support frame 62 and the air nozzle 63 from affecting the punching.

[0066] After the punching is completed, the pressure ring 213 and the first punching head 13 need to be raised. During this process, the protective frame 211 gradually approaches the cutter head base 10. At this time, the pull rope 65 will lose the tension of the reel 653, but because the elastic force of the spring 643 is greater than the elastic force of the coil spring 652, the spring 643 at this time can push the support frame 62 to move downward and pull the pull rope 65 to make it straight. At this time, the support frame 62 will extend downward through the guidance of the lifting guide groove 642 and the steering guide groove 641, and then rotate 90° counterclockwise. Then the support frame 62 can move the air nozzle 63 to the pressure ring 213 At the bottom, the air nozzle 63 can be aligned with the bottom hole of the first punching head 13. At the same time, when the first piston 21 rises, the exhaust will be discharged through the first air inlet hole. The exhausted gas can be introduced into the inside of the hose 661 through the air guide pipe 66. The hose 661 sprays the gas through the air nozzle 63. The cloth inside the discharge hole of the first punching head 13 can be sprayed out through the gas, which can prevent the cut cloth from blocking the discharge hole. After the air nozzle 63 is aligned with the pressure ring 213, it remains in a fixed state. At this time, the coil spring 652 drives the reel 653 to rotate to reel the pull rope 65 for subsequent punching use;

[0067] Other punching heads will operate their corresponding structures in the above process during use to solve the problem of blockage of the discharge hole.

[0068] like Figures 8 to 12 As shown, a material blocking shell 60 is fixed to the top of the pressure ring 213, and an exhaust shell 61 is fixed to the end of the material blocking shell 60 away from the protective frame 211, and an air jet head 67 is inserted inside the exhaust shell 61. The end of the air jet head 67 located outside the exhaust shell 61 is connected to the air guide pipe 66, and a storage shell 611 is provided at the end of the exhaust shell 61 away from the air jet head 67;

[0069] The cut cloth will easily splash when it is ejected by the gas, and the cut cloth returning to the surface of the main cloth will affect the subsequent punching. Therefore, a material blocking shell 60 is set at the top of the pressure ring 213. The material blocking shell 60 can block most of the area outside the punching head. When air is taken in from the air guide pipe 66, a part of the gas is sprayed into the interior of the exhaust shell 61 through the nozzle 67. At this time, due to the drive of the air flow, a negative pressure can be generated at the connection between the exhaust shell 61 and the material blocking shell 60, so that the gas is sucked into the interior. In this process, the splashed cloth can be sucked into the interior of the exhaust shell 61, and then the cloth is sent to the interior of the storage shell 611, which can prevent the cut cloth from splashing. After use, the storage shell 611 can be removed and the cut cloth can be poured out.
