[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1-7 As shown, the multi-punch cutting head disclosed in this invention includes a head base 10, a pneumatic cutting blade body 11, a first drive motor 12, a first punch head 13, a first drive mechanism, a second punch head 14, a second drive mechanism, a third punch head 15, a third drive mechanism, a fourth punch head 16, and a fourth drive mechanism.

[0035] The pneumatic cutting blade body 11 is rotatably mounted in the blade base 10.

[0036] The first drive motor 12 is installed in the cutter head base 10 and is used to drive the pneumatic cutting blade 11 to rotate.

[0037] Specifically, the rotating shaft of the first drive motor 12 is provided with a first synchronous pulley 121, and the outer wall of the pneumatic cutting blade body 11 is provided with a second synchronous pulley. The first synchronous pulley 121 and the second synchronous pulley are surrounded by a first synchronous belt 122, so that the first drive motor 12 drives the first synchronous pulley 121 to rotate, thereby driving the first synchronous belt 122 to rotate, and thus driving the first drive motor 12 to rotate, so as to adjust the cutting position of the pneumatic cutting blade body 11.

[0038] The first punch head 13 is rotatably mounted in the cutter head base 10.

[0039] The first drive mechanism is located in the cutter head base 10 and is used to drive the first punching head 13 to rise and fall.

[0040] In this embodiment, the cutter head base 10 has a first through hole 101, and the cutter head base 10 has a first air inlet and a first air outlet communicating with the first through hole 101. The first driving mechanism includes a first piston 21, a first air inlet pipe 22, a first control box 23, and a first trigger switch 24. The first piston 21 is vertically and vertically disposed in the first through hole 101 and connected to the first punch head 13. The first air inlet pipe 22 communicates with the first air inlet and the first air outlet through the first control box 23. The first trigger switch 24 is disposed outside the first control box 23 and is used to control the communication between the first air inlet pipe 22 and the first air inlet and the first air outlet. It should be understood that the first control box 23 is disposed on the side wall of the cutter head base 10.

[0041] Preferably, when the first trigger switch 24 is triggered, the first control box 23 controls the first air intake pipe 22 to connect with the first air intake hole, so that the gas input through the first air intake pipe 22 enters the first air intake hole to drive the first piston 21 to descend and drive the first punching head 13 to descend, at which time punching operation can be performed; when the first trigger switch 24 is not triggered, the first control box 23 controls the first air intake pipe 22 to connect with the first air outlet hole, so that the gas input through the first air intake pipe 22 enters the first air outlet hole to drive the first piston 21 to rise and drive the first punching head 13 to rise.

[0042] The second punch head 14 is rotatably mounted in the cutter head base 10.

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

[0044] In this embodiment, the cutter head base 10 is provided with a second through hole 102, and the cutter head base 10 is provided with a second air inlet and a second air outlet communicating with the second through hole 102. The second drive mechanism includes a second piston 31 and a second trigger switch 32. The second piston 31 is vertically and vertically disposed in the second through hole 102 and connected to the second punch head 14. The first air inlet pipe 22 is connected to the second air inlet and the second air outlet through the first control box 23. The second trigger switch 32 is disposed outside the first control box 23 and is used to control the opening and closing of the first air inlet pipe 22 with the second air inlet and the second air outlet.

[0045] In other words, the gas input from the first air inlet pipe 22 can enter the first air inlet or the first air outlet, or it can enter the second air inlet or the second air outlet.

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

[0047] The third punch head 15 is rotatably mounted in the cutter head base 10.

[0048] The third drive mechanism is located in the cutter head base 10 and is used to drive the third punching head 15 to rise and fall.

[0049] In this embodiment, the cutter head base 10 is provided with a third through hole 103, and the cutter head base 10 is provided with a third air inlet and a third air outlet communicating with the third through hole 103. The third drive 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 is vertically and vertically disposed in the third through hole 103 and connected to the third punch head 15. The second air inlet pipe 42 is connected to the third air inlet and the third air outlet through the second control box 43. The third trigger switch 44 is disposed outside the second control box 43 and is used to control the connection and disconnection of the second air inlet pipe 42 with the third air inlet 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 connect with the third air inlet, so that the gas input through the second air inlet pipe 42 enters the third air inlet to drive the third piston 41 to descend, thereby driving the third punching head 15 to descend, at which time punching operation can be performed; when the third trigger switch 44 is not triggered, the second control box 43 controls the second air inlet pipe 42 to connect with the third air outlet, so that the gas input through the second air inlet pipe 42 enters the third air outlet to drive the third piston 41 to rise, thereby driving the third punching head 15 to rise.

[0051] The fourth punch head 16 is rotatably mounted in the cutter head base 10.

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

[0053] In this embodiment, the cutter head base 10 is provided with a fourth through hole 104, and the cutter head base 10 is provided with a fourth air inlet and a fourth air outlet communicating with the fourth through hole 104. The fourth drive mechanism includes a fourth piston 51 and a fourth trigger switch 52. The fourth piston 51 is vertically mounted in the fourth through hole 104 and connected to the fourth punch head 16. The second air inlet pipe 42 is connected to the fourth air inlet and the fourth air outlet through the second control box 43. The fourth trigger switch 52 is located outside the second control box 43 and is used to control the connection and disconnection between the second air inlet pipe 42 and the fourth air inlet and the fourth air outlet.

[0054] In other words, the gas input from the second air inlet pipe 42 can enter the third air inlet or the third air outlet, or it can enter the fourth air inlet or the fourth air outlet.

[0055] Preferably, when the fourth trigger switch 52 is triggered, the second control box 43 controls the second air inlet pipe 42 to connect 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, thereby driving the fourth punching head 16 to descend, at which time punching operation can be performed; when the fourth trigger switch 52 is not triggered, the second control box 43 controls the second air inlet pipe 42 to connect 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, thereby driving the fourth punching head 16 to rise.

[0056] In this embodiment, the punches of the first punch head 13, the second punch head 14, the third punch head 15, and the fourth punch head 16 are all of different sizes. It should be understood that because the punches of the first punch head 13, the second punch head 14, the third punch head 15, and the fourth punch head 16 are all of different sizes, different models of punches can be used for punching as needed, offering high flexibility, eliminating the need for replacement operations, and effectively ensuring work efficiency.

[0057] In this embodiment, a second drive motor 17 is provided in the cutter head base 10. The rotating shaft of the second drive motor 17 is provided with a third synchronous pulley 171. The outer walls of the first punch head 13, the second punch head 14, the third punch head 15, and the fourth punch head 16 are all provided with fourth synchronous pulleys. A second synchronous belt 172 is arranged around the third synchronous pulley 171 and the fourth synchronous pulley. The second drive motor 17 drives the third synchronous pulley 171 to rotate, which in turn drives the second synchronous belt 172 to rotate, thereby driving the fourth synchronous pulley to rotate. This allows the first punch head 13, the second punch head 14, the third punch head 15, and the fourth punch head 16 to rotate simultaneously, thereby driving the first punch head 13, the second punch head 14, the third punch head 15, and the fourth punch head 16 to rotate for punching.

[0058] It should be understood that the second drive motor 17 drives the first punch head 13, the second punch head 14, the third punch head 15 and the fourth punch head 16 to rotate simultaneously. However, when punching is actually needed, only when the punch head descends will it play a real punching role. Although the punch head that does not descend is also rotating, it will not play a punching role.

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

[0060] A support plate 181 is provided on the top of the mounting plate 18. A first slide rail 182 is provided on one side of the mounting plate 18. A first slider 183 is slidably disposed in the first slide rail 182. A third drive motor 19 is disposed in the support plate 181. One end of the first lead screw 20 is connected to the rotating shaft of the third drive motor 19 so that the first lead screw 20 can be rotated by the third drive motor 19.

[0061] Preferably, a protrusion 100 extends from one side of the cutter head base 10, and the protrusion 100 has a first threaded hole. The first lead screw 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. When the third drive motor 19 drives the first lead screw 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 of the cutter head base 10. The clamping structure includes a punch head protection seat 131 installed at the bottom of the cutter head base 10. The punch head protection seat 131 is located below the first punch head 13. A protective frame 211 is installed at the bottom of the first piston 21. A guide groove 132 is opened on the side of the punch head protection seat 131 near the protective frame 211. A guide roller 212 is rotatably connected to one side of the top of the protective frame 211. The guide roller 212 is slidably connected inside the guide groove 132. A pressure ring 213 is fixed at the bottom of the protective frame 211. The bottom of the first punch head 13 is located in the middle of the pressure ring 213. The bottom of the pressure ring 213 and the bottom of the first punch head 13 are on the same horizontal line. The cutter head base 10 is also equipped with clamping structures at the bottom of the second punch head 14, the third punch head 15 and the fourth punch head 16.

[0063] During the punching process, when the first piston 21 drives the first punch head 13 to move downwards, the bottom end of the first piston 21 will simultaneously drive the protective frame 211 to move downwards. At this time, the protective frame 211 drives the pressure ring 213 to move downwards. During this process, the guide roller 212 moves inside the guide groove 132, which can guide the protective frame 211. The pressure ring 213 and the first punch head 13 descend synchronously. When the guide roller 212 contacts the fabric surface, it will flatten the outer area of ​​the fabric where the punching is required. At this time, the first punch head 13 punches the fabric inside the pressure ring 213. This can prevent the fabric from deforming due to the rotation of the first punch head 13 during the punching process, which would affect the punching quality and achieve a better punching effect.

[0064] like Figures 8 to 11As shown, the protective frame 211 has a telescopic hole 64 inside. Lifting guide grooves 642 are provided on both sides of the telescopic hole 64. A steering guide groove 641 is provided at the bottom of the lifting guide grooves 642. A support frame 62 is provided below the protective frame 211. An air nozzle 63 is installed at the end of the support frame 62 near the pressure ring 213. A rotating shaft is fixed at the end of the support frame 62 away from the air nozzle 63. Protrusions 621 are fixed on both sides of the top of the rotating shaft. The protrusions 621 are slidably connected inside the steering guide groove 641. A spring 643 is provided at the top of the rotating shaft and is located inside the telescopic hole 64. A pull rope 65 passes through the inside of the spring 643. The bottom end of the pull rope 65 is fixedly connected to the top of the rotating shaft of the support frame 62. A support seat 651 is provided above the pull rope 65. The top end of the support base 651 is fixedly connected to the bottom end of the cutter head base 10. The inside of the support base 651 is rotatably connected to the winding shaft 653. The top end of the pull rope 65 is wound around the outside of the winding shaft 653. The outer ends of the winding shaft 653 are fixed with coil springs 652. The other end of the coil springs 652 is fixedly connected to the support base 651. The bottom end of the air nozzle 63 is fixed with a hose 661. The other end of the hose 661 is fixed with an air guide pipe 66. The other end of the air guide pipe 66 is connected to the first air inlet of the first through hole 101. There are four sets of air guide pipes 66. The other three sets of air guide pipes 66 are connected to the second air inlet of the second through hole 102, the third air inlet of the third through hole 103, and the fourth air inlet of the fourth through hole 104, respectively. The inside of the first punch head 13 is provided with a discharge hole.

[0065] During the punching process, the portion of the fabric cut off by the first punch head 13 is discharged to the outside through its discharge hole. However, the cut fabric is prone to getting stuck inside the discharge hole. The accumulation of fabric in the discharge hole will affect the subsequent punching by the first punch 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 is pulled, and the support base 651 remains fixed at the bottom 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 a certain distance, the pull rope 65 outside the take-up shaft 653 is... When fully unwound, the take-up shaft 653 pulls the pull rope 65 in the opposite direction. The pull rope 65 pulls the support frame 62. Under the action of the protrusion 621 at the end of the support frame 62 shaft and the steering guide groove 641, the support frame 62 rotates 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 compressed. When the shaft of the support frame 62 is retracted, the pressure ring 213 and the first punch head 13 descend to the position of contacting the fabric. During this process, the support frame 62 drives the air nozzle 63 away from the bottom of the pressure ring 213, which can prevent the support frame 62 and the air nozzle 63 from affecting the punching.

[0066] After punching is completed, the pressure ring 213 and the first punch 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 winding shaft 653. However, because the elastic force of the spring 643 is greater than that of the coil spring 652, the spring 643 can push the support frame 62 downward and pull the pull rope 65 to make it taut. At this time, the support frame 62 will first extend downward through the guidance of the lifting guide groove 642 and the turning guide groove 641, and then rotate 90° counterclockwise. Subsequently, the support frame 62 can move the air nozzle 63 to the pressure ring 213. At the bottom, the jet nozzle 63 can be aligned with the bottom hole of the first punch head 13. At the same time, when the first piston 21 rises, it will exhaust through the first air inlet. The exhaust gas can be guided into the inside of the hose 661 through the air guide pipe 66. The hose 661 sprays the gas out through the jet nozzle 63. The gas can spray out the cloth inside the discharge hole of the first punch head 13, which can prevent the cut cloth from blocking the discharge hole. After the jet nozzle 63 is aligned with the pressure ring 213, it remains in a fixed state. At this time, the coil spring 652 drives the winding shaft 653 to rotate and wind up the pull rope 65 for subsequent punching.

[0067] Other punching heads will operate according to the above process during use to solve the problem of clogging of the discharge hole.

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

[0069] When the cut fabric is ejected by gas, it is easy for it to splatter, and the cut fabric returning to the surface of the main fabric will affect the subsequent punching. Therefore, a baffle shell 60 is set at the top of the pressure ring 213. The baffle shell 60 can block most of the area outside the punching head. When air enters the air duct 66, some of the gas is injected into the air extraction shell 61 through the jet nozzle 67. At this time, due to the airflow, a negative pressure is generated at the connection between the air extraction shell 61 and the baffle shell 60, which draws in the gas. During this process, the splattered fabric can be drawn into the air extraction shell 61. Then the fabric is sent into the storage shell 611 to prevent the cut fabric from splattering. After use, the storage shell 611 can be removed and the cut fabric poured out.
