DETAILED DESCRIPTION

[0057] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0058] Die-cutting technology is typically used to punch materials into desired shapes. This process generates waste material in the equipment. If not removed, this waste material can affect both the efficiency of the die-cutting process and the quality of the die-cut product.

[0059] To overcome the shortcomings of the existing technology, after repeated deliberation and verification, the inventors discovered that by adding an air duct to the punch, positive air pressure could be applied to the waste material during the punching process, causing the pressure on the upper surface of the waste to be greater than that on the lower surface, blowing the waste off and ensuring smooth waste discharge. Furthermore, the application of positive air pressure is unaffected by the state of the waste material and is applicable to any type of waste material. Furthermore, the air duct is located within the punch, eliminating the need for additional air ducts and devices in the lower die, simplifying the lower die structure.

[0060] In view of this, the present application provides a die-cutting blanking device, comprising:

[0061] The upper die is equipped with a positive pressure airway;

[0062] The punch is connected to one side of the upper die, an upper cutter is provided on the circumference of the punch away from the upper die, and the punch is provided with a plurality of punch air channels, which are connected to the positive pressure air channel;

[0063] The lower die is provided with a blanking port, which is opposite to the punch;

[0064] The lower cutter is connected to the lower die and is provided with a lower cutting edge, and the lower cutting edge matches the shape of the punch.

[0065] By adding multiple punch air ducts to the punch, the upper and lower cutters of the punch cooperate to cut the material. Positive air pressure is then supplied through the positive pressure air duct, which then enters the punch air duct. These multiple punch air ducts apply pressure to the waste material on the upper cutter, blowing it off. The pressure is uniform, and the applied positive air pressure is unaffected by the state of the waste material, making it suitable for any type of waste material. Blowing air through the punch air duct ensures that the pressure on the upper surface of the waste material is greater than that on the lower surface, thereby ensuring the waste material moves toward the blanking port, thereby ensuring smooth discharge. This eliminates the need for additional waste removal procedures, simplifies the die-cutting process, and improves the efficiency of the die-cutting operation. Furthermore, since the waste material is discharged smoothly after die-cutting, it does not affect subsequent operations, thereby improving the quality of the die-cut product. The punch air duct is located within the punch, eliminating the need for additional air ducts and devices in the lower die, simplifying the structure.

[0066] The contents of this application will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the contents of this application more clearly and in detail.

[0070] like Figure 1 and Figure 5 As shown, the die-cutting blanking device 100 provided in the embodiment of the present application is used to cut the material 200.

[0071] The die-cutting and blanking device 100 includes an upper die 10, a punch mounting plate 20, a punch 30, a lower die 40, a lower cutter 50, and a recovery mechanism. The punch mounting plate 20 is connected to the upper die 10. The punch 30 is attached to the side of the punch mounting plate 20 facing away from the upper die 10. The lower cutter 50 and the recovery mechanism are respectively connected to the lower die 40. The upper die 10 is used to move the punch mounting plate 20 and punch 30 toward the lower die 40, thereby cooperating with the lower cutter 50 to cut the material 200. The resulting waste falls into the recovery mechanism.

[0072] like Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown, in one possible implementation, the upper die 10 is provided with a positive pressure air channel 11. The punch mounting plate 20 is provided with a connecting air channel 21 connected to the positive pressure air channel 11. The punch 30 is provided with an upper cutter 31 on the circumference of a side away from the punch mounting plate 20. The punch 30 is provided with a plurality of punch air channels 32, which are connected to the connecting air channel 21.

[0073] After the upper cutter 31 of the punch 30 cooperates with the lower cutter 50 to complete the cutting of the material 200, positive air pressure is provided through the positive pressure air channel 11, and enters the punch air channel 32 through the connecting air channel 21. Multiple punch air channels 32 apply pressure to the waste on the upper cutter 31, thereby blowing the waste off.

[0074] In one possible implementation, the lower die 40 is provided with a blanking opening 41, which is opposite to the punch 30. The lower cutter 50 is provided with a lower cutting edge 51, which matches the shape of the punch 30. The recovery mechanism is connected to the blanking opening 41.

[0075] The material 200 is conveyed along the conveyor belt and passes through the upper surface of the lower blade 51 of the die-cutting blanking device 100. The punch 30 falls and falls below the upper surface of the lower blade 51, cutting the material 200 and generating waste.

[0076] After the material 200 is cut, the waste material is blown off by the punch air channel 32 , passes through the lower cutting edge 51 and the blanking port 41 in sequence, and falls into the recycling mechanism.

[0077] The die-cutting blanking device 100 provided in the present application adds multiple punch air channels 32 to the punch 30, and provides a connecting air channel 21 connected to the positive pressure air channel 11 and the punch air channel 32 on the punch mounting plate 20. After the upper cutter 31 of the punch 30 cooperates with the lower cutter 50 to complete the cutting of the material 200, positive air pressure is provided through the positive pressure air channel 11, and enters the punch air channel 32 through the connecting air channel 21. The multiple punch air channels 32 apply pressure to the waste on the upper cutter 31, which can effectively blow the waste generated during the cutting process off the upper cutter 31. The pressure is uniform, and the positive air pressure applied is not affected by the state of the waste, which can effectively remove the waste. It is suitable for any type of waste. Blowing air through the punch air channel 32 can ensure that the pressure on the upper surface of the waste is greater than that on the lower surface, thereby ensuring that the waste moves toward the blanking port 41 and is discharged into the recovery mechanism, avoiding the problem of waste blockage or residue. No additional waste removal process is required, which simplifies the die-cutting process and improves the efficiency of the die-cutting operation. At the same time, since the waste is discharged smoothly after die-cutting, the waste will not affect subsequent operations, thus improving the quality of the die-cut products.

[0078] Please also refer to Figure 4The punch air channel 32 is arranged on the punch 30, and the lower die 40 and the lower cutter 50 do not require the arrangement of additional air channels and devices, thereby simplifying the overall structure.

[0079] like Figure 11 、 Figure 12 and Figure 13 As shown, in one possible implementation, the punch air channel 32 passes through the punch 30 along the vertical direction x.

[0080] The punch air channel 32 designed to penetrate the punch allows airflow to pass directly through the punch 30. The airflow can directly act on the waste along the shortest path, reducing airflow loss, lowering gas flow resistance, and improving air pressure utilization efficiency, thereby applying a more direct and stronger air pressure on the waste, ensuring that more gas momentum acts on the waste, helping to more effectively blow the waste off the upper cutter 31, and improving the waste removal efficiency.

[0081] The through-hole design also reduces the complex path of the punch air passage 32 within the punch 30, simplifying manufacturing and processing and reducing production costs. The through-hole punch air passage 32 reduces potential blockage points, lowering maintenance requirements and the risk of failure, thereby increasing the reliability and service life of the device. Due to the optimized airflow path and efficient use of air pressure, the device requires less compressed air during operation, thereby reducing energy consumption.

[0082] In a possible implementation, the connecting air channel 21 passes through the punch mounting plate 20 along the vertical direction x.

[0083] The through-hole connecting air channel 21 allows airflow to be transferred directly from the positive pressure air channel 11 of the upper die 10 to the punch air channel 32, thereby reducing airflow loss, improving the efficiency of air pressure utilization, and ensuring that airflow effectively affects the waste material. Because the air channel is straight, the airflow encounters less resistance and loss during transmission, increasing the air pressure acting on the waste material and improving the overall efficiency of the system.

[0084] The through-hole design also simplifies the internal structure of the punch mounting plate 20, making manufacturing and processing easier and reducing production costs. This simplified structure makes the system easier to inspect and maintain, reducing maintenance complexity and costs. The reduced number of bends and connection points in the airway reduces the risk of blockage and leakage, thereby increasing the reliability and service life of the device.

[0085] In a possible implementation, the positive pressure air channel 11 passes through the upper mold 10 along the vertical direction x.

[0086] The through-hole positive pressure airway 11 allows airflow to be transferred directly from the air source to the connecting airway 21, thereby reducing airflow losses and ensuring that the airflow can be transferred to the punch airway 32 with maximum efficiency, effectively acting on the waste material. Because the airway is straight, the airflow encounters less resistance and loss during transmission, thereby improving the overall efficiency and response speed of the system.

[0087] The through-hole airway design also simplifies the internal structure of the upper mold 10, making manufacturing and processing easier and reducing production and assembly complexity. This simplified structure makes the system easier to inspect, clean, and maintain, reducing maintenance complexity and costs. The reduced number of bends and connection points in the airway reduces the risk of blockage and leakage, thereby improving the reliability and service life of the device.

[0088] In a possible implementation, the axis of the connecting airway 21 coincides with the axis of the positive pressure airway 11 .

[0089] When the axis of the connecting air channel 21 coincides with the axis of the positive pressure air channel 11, the airflow can be transmitted along a straight path, reducing bends and turns in the airflow path, thereby minimizing airflow loss and resistance, improving the efficiency of airflow transmission, and allowing the airflow to be transmitted to the punch air channel 32 more quickly and effectively, enhancing the effect of waste removal and improving the efficiency of the entire die-cutting process. Due to the high efficiency of airflow transmission, the system requires less compressed air, thereby reducing energy consumption and operating costs.

[0090] This axis-aligned design also simplifies the airway layout, eliminating complex connections and transition components, thereby reducing manufacturing and assembly complexity. This simplified structure makes the system easier to inspect and maintain, reducing maintenance complexity and costs. The reduced number of bends and connection points in the airway reduces the risk of blockage and leakage, thereby improving system reliability and service life.

[0091] In a possible implementation, along the vertical direction x, projections of the plurality of punch air channels 32 are arranged on the punch 30 in a matrix, and the distance between any two adjacent punch air channels 32 is the same.

[0092] The punch air channels 32 arranged in a matrix ensure that the airflow is more evenly distributed on the surface of the punch 30. The distance between any two adjacent punch air channels 32 is consistent, which helps to apply consistent air pressure throughout the entire cutting area. The waste can be subjected to the same air pressure throughout the cutting area, thereby reducing the possibility of waste residue and improving the efficiency of waste removal.

[0093] The punch air channels 32 arranged in a matrix can increase the force of the airflow on the waste material, make the use of the airflow more efficient, reduce the waste of the airflow, and thus reduce energy consumption.

[0094] Please also refer to Figure 14 In one possible implementation, a lower groove 33 is provided on the side of the punch 30 away from the punch mounting plate 20, and multiple punch air channels 32 are connected to the lower groove 33. The lower groove 33 is used to form a lower uniform pressure cavity 34 with the waste during die cutting.

[0095] The lower groove 33 and the waste material form a lower uniform pressure cavity 34, which can provide a uniform pressure distribution area during the die-cutting process, helping to ensure that consistent pressure is applied throughout the cutting area. The airflow can act more evenly on the waste material, enhancing the waste removal effect and thus reducing the possibility of waste residue.

[0096] At the same time, the design of the lower groove 33 can help stabilize the airflow and reduce airflow interference that may occur during the die-cutting process, thereby improving the stability and consistency of cutting.

[0097] In a possible implementation, along the vertical direction, the depth of the lower groove 33 is L1, and the range of L1 is 0.01 mm-0.5 mm.

[0098] The shallow depth of the lower groove 33, ranging from 0.01mm to 0.5mm, allows for precise control of the pressure distribution within the lower uniform pressure chamber 34, thereby facilitating the application of appropriate pressure during the die-cutting process. Furthermore, the shallower lower groove 33 shortens the airflow path, reducing airflow losses and energy consumption within the lower uniform pressure chamber 34 and improving overall system efficiency. Furthermore, the shallower lower groove 33 helps form a stable and uniform lower uniform pressure chamber 34, enabling more effective waste removal and reducing the likelihood of waste residue.

[0099] Furthermore, the shallower lower groove 33 reduces the amount of material removed, lowers the complexity and cost of mold processing, and also reduces material waste.

[0100] In a possible implementation, the depth of the lower groove 33 is 0.1 mm.

[0101] In a possible implementation, along the vertical direction x, the projection area of ​​the lower groove 33 on the punch 30 is greater than or equal to half of the waste area.

[0102] The larger projected area of ​​the lower groove 33 helps to discharge the waste smoothly, reduces the risk of waste clogging during the cutting process, and improves the operating efficiency of the equipment.

[0103] Please also refer to Figure 3 、 Figure 9 、 Figure 10 and Figure 15In one possible implementation, an upper groove 22 is provided on the side of the punch mounting plate 20 facing the punch 30, and an upper uniform pressure chamber 23 is formed between the upper groove 22 and the punch 30, and the upper uniform pressure chamber 23 is connected to the connecting airway 21 and multiple punch airways 32.

[0104] The upper uniform pressure chamber 23 can provide a uniform air pressure distribution area between the connecting air channel 21 and the multiple punch air channels 32, ensuring that the airflow is evenly distributed before entering the punch air channel 32, thereby applying consistent pressure in the entire cutting area. Due to the uniform distribution of the airflow in the upper uniform pressure chamber 23, the waste can be subjected to the same air pressure in the entire cutting area, thereby enhancing the waste removal effect and reducing the possibility of waste residue.

[0105] At the same time, the presence of the upper pressure chamber 23 buffers and evens out the airflow before it enters the punch airway 32, helping to stabilize the airflow, reduce airflow turbulence and loss, and improve airflow efficiency. By optimizing airflow distribution and reducing airflow loss, the system requires less compressed air, thereby reducing energy consumption and operating costs.

[0106] In a possible implementation, the punch mounting plate 20 is provided with a transition air channel 24. The transition air channel 24 is connected between the connecting air channel 21 and the upper groove 22. The aperture of the transition air channel 24 increases along the direction from the upper die 10 to the punch 30.

[0107] Optionally, the aperture of the transition air channel 24 gradually increases along the direction from the upper die 10 to the punch 30 .

[0108] Optionally, the rate of change of the aperture of the transition air channel 24 is continuous to reduce gas turbulence.

[0109] The transition air channel 24 can provide an airflow transition area between the connecting air channel 21 and the upper groove 22. The gradually increasing aperture design can effectively reduce the airflow velocity while increasing the pressure stability of the airflow, which helps to buffer and homogenize the airflow before entering the upper groove 22, ensuring that the airflow is more stable and uniform when entering the punch air channel 32, helping to more effectively remove waste, reduce the possibility of waste residue, and ensure the smooth progress of the cutting process.

[0110] At the same time, the gradually expanding transition air duct 24 design can reduce airflow turbulence and disturbance, reduce airflow losses, and improve airflow utilization efficiency. By reducing airflow turbulence and disturbance, the system's energy consumption and operating noise are reduced, improving the comfort of the operating environment.

[0111] In a possible implementation, along the vertical direction x, the depth of the upper groove 22 is L2, and the range of L2 is 0.1 mm-5 mm.

[0112] The upper groove 22, with a depth ranging from 0.1mm to 5mm, provides flexible space for adjusting the air pressure distribution within the upper equalizing chamber 23, helping to adjust the air pressure according to different materials and cutting requirements to achieve the best cutting effect. This helps to form a uniform air pressure distribution within the upper equalizing chamber 23, ensuring that the airflow is fully buffered and evened before entering the punch airway 32, thereby improving cutting accuracy and consistency, facilitating more effective waste removal, reducing the possibility of waste residue, and ensuring a smooth cutting process.

[0113] At the same time, through effective airflow management, the system requires less compressed air, thereby reducing energy consumption and operating costs.

[0114] In a possible implementation, the depth of the upper groove 22 is 1 mm.

[0115] In one possible implementation, the continuous air duct composed of the upper die 10, the punch mounting plate 20, and the internal cavity of the punch 30 is roughly in the form of a single shower-shaped dense method, but is not limited to this. In other possible implementations, the continuous air duct can also be a double claw-shaped dense structure, a double shower-shaped dense structure, or other similar structures, which have similar effects.

[0116] In one possible implementation, there are multiple connecting air channels 21, each of which is connected to the positive pressure air channel 11, and each of the punch air channels 32 is connected to the corresponding connecting air channels 21. That is, each connecting air channel 21 is connected to some of the punch air channels 32, and each of the punch air channels 32 is connected to a corresponding connecting air channel 21.

[0117] The design of multiple connecting air channels 21 effectively distributes airflow, ensuring that each punch air channel 32 receives sufficient air pressure, ensuring efficient use of airflow and improving the efficiency of the entire system. The design of multiple connecting air channels 21 reduces cross-interference and losses in the airflow path, improving airflow stability and the overall efficiency of the system.

[0118] Through independent airflow channels, the system can apply uniform and consistent pressure throughout the cutting area, thereby improving cutting accuracy and consistency and reducing cutting defects. Each punch air channel 32 can obtain direct and stable airflow support, which helps to more effectively remove waste and reduce the possibility of waste residue.

[0119] Each punch air channel 32 is connected to the positive pressure air channel 11 through an independent connecting air channel 21, providing independent control capability for each punch 30 and allowing precise adjustment of the air pressure in different areas to adapt to different cutting requirements and material properties.

[0120] In one possible implementation, an upper groove 22 is provided on the side of the punch mounting plate 20 facing the punch 30, and an upper uniform pressure chamber 23 is formed between the upper groove 22 and the punch 30. The upper uniform pressure chamber 23 corresponds to the punch airway 32 respectively, and the upper uniform pressure chamber 23 connects the corresponding connecting airway 21 and the corresponding punch airway 32.

[0121] The independent upper uniform pressure chamber 23 design reduces interference and turbulence between airflows, thereby improving the stability of the airflow and the overall efficiency of the system.

[0122] Each upper uniform pressure chamber 23 is connected to the corresponding connecting air channel 21 and punch air channel 32, providing independent control capability for each punch 30, allowing precise adjustment of the air pressure in different areas to adapt to different cutting requirements and material properties.

[0123] In a possible implementation, a vacuum breaking port 35 is further provided on one side of the punch 30 where the upper cutter 31 is provided. The vacuum breaking port 35 is connected to the outside atmosphere.

[0124] During the die-cutting process, the cut waste may adhere to the upper cutter 31 or the punch 30 due to the vacuum effect. The design of the vacuum breaking port 35 allows outside air to enter, destroying the vacuum effect, thereby ensuring that the air pressure on the upper and lower surfaces of the cut waste is consistent during the rapid rise of the upper mold 10, preventing the waste from being adsorbed and the waste from being affected by the vacuum effect, reducing the problem of the waste being carried up by the moving mechanism, ensuring that the waste can fall off smoothly, and the waste can be more easily blown away or dropped by the airflow, thereby improving the efficiency of waste removal and reducing the possibility of waste residue.

[0125] In a possible implementation, the vacuum breaking port 35 is located on one side of the plurality of punch air passages 32 .

[0126] The vacuum breaking port 35 is arranged beside the plurality of punch air passages 32 so that the flow of gas in the punch air passages 32 and the vacuum breaking port 35 becomes smooth, thereby reducing the vortex phenomenon during ventilation and making it difficult for waste materials to be carried away.

[0127] In a possible implementation, the upper die 10 and the punch mounting plate 20 are further provided with a vacuum breaking air duct 12 , which is connected to the vacuum breaking port 35 and the outside atmosphere.

[0128] The vacuum breaking air channel 12 provides a direct passage, allowing the outside atmosphere to quickly enter the area where the vacuum breaking port 35 is located, thereby effectively breaking the vacuum effect and preventing waste from adhering to the upper cutter 31 or the punch 30 due to vacuum adsorption.

[0129] By integrating the vacuum air passage 12 in the upper die 10 and the punch mounting plate 20, the system design is more compact, the need for external pipes and connectors is reduced, and the overall design and installation of the system are simplified.

[0130] In a possible implementation, the vacuum breaking port 35 passes through the punch 30 along the vertical direction x.

[0131] In a possible implementation, the vacuum air channel 12 passes through the punch mounting plate 20 and the upper die 10 along the vertical direction x.

[0132] In a possible implementation, the axis of the vacuum breaking port 35 , the axis of the vacuum breaking air channel 12 on the punch mounting plate 20 , and the axis of the vacuum breaking air channel 12 on the upper die 10 coincide with each other.

[0133] The through-designed vacuum breaking port 35 and the vacuum breaking air passage 12 allow airflow to be directly transferred from the upper mold 10 to the vacuum breaking port 35 , thereby reducing airflow loss and improving the efficiency of breaking the vacuum effect.

[0134] In a possible implementation, the die-cutting and blanking device 100 further includes a guide post 13 , which is connected to a side of the upper die 10 away from the punch mounting plate 20 , and is used to connect to a driving end of a driving member.

[0135] The guide pillars 13 provide additional support and guidance to ensure that the upper mold 10 moves more smoothly and precisely in the vertical direction, and ensure that the upper mold 10 and the lower mold 40 always maintain the correct alignment position during operation, reduce cutting errors caused by mold offset or shaking, and improve cutting accuracy and consistency.

[0136] In a possible implementation, the guide pillar 13 is connected to the upper mold 10 by expansion connection.

[0137] In a possible implementation, a crankshaft driven by a servo motor controls the guide pillar 13 to move up and down, thereby driving the upper mold 10 to move up and down.

[0138] In a possible implementation, the punch mounting plate 20 is provided with a through hole 25 , and the upper die 10 , the punch mounting plate 20 and the punch 30 are connected via a connector passing through the through hole 25 .

[0139] Through the combination of the through hole 25 and the connecting piece, the upper die 10, the punch mounting plate 20 and the punch 30 form a whole, which enhances the stability of the entire die structure, helps to reduce vibration and displacement during operation, and improves the accuracy and consistency of cutting.

[0140] The design of the through-holes 25 and the connectors makes assembly and disassembly of the components easier, facilitates quick replacement or maintenance of the mold components, and reduces assembly time and downtime.

[0141] The connectors precisely position the individual components via the through-holes 25, ensuring they maintain correct alignment during operation, reducing the risk of die misalignment and thereby improving the accuracy of the die-cutting process.

[0142] In a possible implementation, the die-cutting and blanking device 100 further includes a control valve, which is provided on the positive pressure air channel 11 .

[0143] The control valve can adjust the air pressure entering the positive pressure airway 11 to the desired level, helping to blow waste off the upper cutter 31 and improve waste removal efficiency. By adjusting the control valve, the air pressure can be adjusted according to different materials and cutting requirements, providing greater flexibility and adaptability to meet the requirements of various application scenarios. The control valve can also quickly respond to changes in system requirements and make real-time adjustments to ensure the continuity and stability of the die-cutting process. The control valve can adjust the air flow according to actual needs, avoiding unnecessary air pressure loss and energy consumption, thereby improving the energy efficiency of the system and reducing operating costs.

[0144] In a possible implementation, the control valve is a solenoid valve, which controls the compressed gas to enter the positive pressure airway 11 .

[0145] In a possible implementation, the compressed gas supply duration is 0.15 s, and the compressed gas is turned on at the moment when the punch 30 moves down to the position to complete the material cutting.

[0146] After the cutting is completed, compressed air is provided by the air source connected to the solenoid valve to blow off the cut waste. The vacuum breaking air duct 12 passing through the upper die 10 and the punch mounting plate 20 and the vacuum breaking port 35 of the punch 30 are connected to the atmosphere to ensure that the cut waste will not be brought up or taken out during the up and down movement of the upper die 10, the punch mounting plate 20, the punch 30 and the guide column 13. After the material is cut from the lower blade 51, the waste generated is blown off by the gas blown out of the punch air duct 32, passes through the lower die 40, and falls into the recovery mechanism.

[0147] In a possible implementation, the die-cutting blanking device 100 further includes a pressing plate 70 , which is provided with a cutting opening 71 , the cutting opening 71 being opposite to the punch 30 , and the pressing plate 70 is used to cooperate with the lower cutter 50 to press the material.

[0148] The hold-down plate 70 compresses the material, preventing it from shifting or sliding during the cutting process, thereby improving cutting accuracy and consistency. This compacted material produces a sharper, neater cut edge, enhancing cut quality and reducing burrs and irregularities. Working in conjunction with the lower cutter 50, the hold-down plate 70 compresses and cuts the material in a single step, streamlining the process and increasing production efficiency.

[0149] In one possible implementation, the die-cutting blanking device 100 further includes a tray 80 connected to the side of the lower die 40 facing the upper die 10 , and the tray 80 is used to support the material 200 . The lower cutter 50 is disposed in the tray 80 , and the tray 80 is used to cooperate with the pressing plate 70 .

[0150] The tray 80 provides a stable mounting platform for the lower cutter 50, ensuring that the lower cutter 50 remains stable and precisely positioned during the cutting process, thereby improving cutting accuracy and consistency. The tray 80, in conjunction with the hold-down plate 70, effectively secures the material, preventing it from moving or sliding during the cutting process, thereby improving cut quality and reducing burrs and irregular cuts.

[0151] In one possible implementation, the die-cutting blanking device 100 also includes a blanking connecting plate 90, which is connected to the side of the lower mold 40 away from the upper mold 10. The blanking connecting plate 90 is provided with a blanking port 91, which connects the blanking port 41 with the recovery mechanism.

[0152] The blanking connecting plate 90 provides a direct channel to guide the waste generated during the cutting process from the blanking port 41 to the recycling mechanism, thereby simplifying the collection and treatment of the waste and improving the efficiency of waste management.

[0153] In a possible implementation, the die-cutting blanking device 100 further includes a drop bucket 60 , which connects the blanking connecting plate 90 and the recovery mechanism.

[0154] The drop bucket 60 provides a guide channel to allow the waste to flow smoothly from the material discharge connection plate 90 into the recovery mechanism, ensuring that the waste can be efficiently transferred under the action of gravity and reducing the risk of blockage.

[0155] The enclosed structure of the drop bucket 60 helps prevent waste from spilling or scattering during the transfer process, keeping the work area clean and safe. The drop bucket 60 acts as a buffer as waste flows from the material delivery connecting plate 90 to the recycling mechanism, reducing the impact of waste on the recycling mechanism and extending its service life.

[0156] In a possible implementation, along the vertical direction x, the size of the upper cutter 31 ranges from 0.1 mm to 5 mm.

[0157] The upper cutter 31, with a size range of 0.1mm to 5mm, can adapt to the thickness of a variety of materials, from film to thicker cardboard or plastic, which gives the equipment greater flexibility in processing different materials. Upper cutters 31 of different sizes can be selected according to the characteristics of the material, ensuring a neat and smooth cutting edge, reducing burrs and irregular cuts, and improving cutting quality.

[0158] In a possible implementation, along the vertical direction x, the size of the upper cutter 31 is 2.5 mm.

[0159] In a possible implementation, along the horizontal direction, the width of the upper cutter 31 is the same as the width of the edge of the punch 30 connected to the upper cutter 31 .

[0160] When the width of the upper cutter 31 is the same as the width of the connecting edge of the punch 30, the cutting force can be evenly distributed throughout the cutting area, reducing stress concentration and the risk of material tearing or deformation during the cutting process, thereby improving the accuracy and consistency of cutting, especially in die-cutting applications that require high precision.

[0161] The same width provides better structural symmetry and stability, reduces vibration and deviation that may occur during cutting, and improves the overall stability of the equipment.

[0162] In a possible implementation, the cutting material is a tab, and the width of the upper cutter 31 ranges from 20 mm to 80 mm.

[0163] In a possible implementation, the width of the upper cutter 31 is 59 mm.

[0164] In a possible implementation, the blade angle of the upper cutter 31 ranges from 10° to 30°.

[0165] A blade angle in the range of 10° to 30° can provide good cutting performance for the upper cutter 31. A smaller blade angle (close to 10°) is suitable for materials that require fine cutting, while a larger blade angle (close to 30°) is suitable for thicker or harder materials. Appropriate blade angle design can effectively reduce the resistance encountered during the cutting process, making the cutting process smoother and improving cutting efficiency. At the same time, it helps to obtain a smooth cutting edge, reduce burrs and irregular cuts, and thus improve cutting quality.

[0166] In a possible implementation, the blade angle range of the upper cutter 31 is 20°.

[0167] In a possible implementation, the lower cutting edge 51 and the punch 30 are clearance-fitted.

[0168] A clearance fit allows for precise control of the distance between the punch 30 and the lower blade 51, improving cutting accuracy and consistency, ensuring a clean, smooth cut edge. Proper clearance reduces material compression and deformation during cutting, particularly when working with soft or thin materials, effectively preventing tearing or warping. Furthermore, a clearance fit reduces direct contact and friction between the punch 30 and the lower blade 51, slowing tool wear and extending its service life.

[0169] In a possible implementation, the gap between the lower blade 51 and the punch 30 is in the range of 0.2 mm to 1 mm.

[0170] In a possible implementation, in the length direction, the gap between the lower blade 51 and the punch 30 is 0.6 mm; in the width direction, the gap between the lower blade 51 and the punch 30 is 0.63 mm.

[0171] In a possible implementation, along the vertical direction x, the size of the punch 30 ranges from 5 mm to 40 mm.

[0172] Punches 30, with sizes ranging from 5mm to 40mm, can adapt to a variety of cutting needs, from small, fine die-cutting tasks to larger area cutting applications, providing greater flexibility. Larger punches 30 (close to 40mm in size) can cover a larger cutting area in a single operation, thereby improving production efficiency and reducing processing time. Smaller punches 30 (close to 5mm in size) can provide better control and accuracy, suitable for small cutting tasks requiring high precision, ensuring cutting accuracy.

[0173] In a possible implementation, along the vertical direction x, the dimension of the punch 30 is 20 mm.

[0174] In one possible implementation, in order to ensure the rounded corner shape requirements of the cut material, the punch 30 is designed with rounded corners, and the two ends of the upper cutter 31 are rounded in coordination with the rounded corners of the punch 30, and the corresponding positions of the lower blade 51 and the punch 30 are also rounded.

[0175] The die-cutting and blanking device 100 provided in the embodiment of the present application includes an upper die 10, a punch 30, a lower die 40, a lower cutter 50 and a recovery mechanism. The upper die 10 is provided with a positive pressure air duct 11. The punch 30 is connected to one side of the upper die 10, and an upper cutter 31 is provided on the circumference of the side of the punch 30 away from the upper die 10. The punch 30 is provided with a plurality of punch air ducts 32, and the punch air ducts 32 are connected to the positive pressure air duct 11. The lower die 40 is provided with a blanking port 41, and the blanking port 41 is opposite to the punch 30. The lower cutter 50 is connected to the lower die 40 and is provided with a lower cutting edge 51, and the lower cutting edge 51 matches the shape of the punch 30.

[0176] By adding multiple punch air ducts 32 to the punch 30, the upper cutter 31 of the punch 30 cooperates with the lower cutter 50 to complete the cutting of the material. Positive air pressure is provided through the positive pressure air duct 11 and enters the punch air duct 32. The multiple punch air ducts 32 apply pressure to the waste material on the upper cutter 31, blowing the waste material off. The pressure is uniform, and the applied positive air pressure is not affected by the state of the waste material. It is suitable for any type of waste material. Blowing air through the punch air duct 32 can ensure that the pressure on the upper surface of the waste material is greater than that on the lower surface, thereby ensuring that the waste material moves toward the blanking port 41, thereby ensuring the smooth discharge of the waste material. There is no need to add additional waste removal operation procedures, simplifying the die-cutting process and improving the efficiency of the die-cutting operation. At the same time, since the waste material is smoothly discharged after die-cutting, the waste material will not affect subsequent operations, thereby also improving the quality of the die-cut product. The punch air duct 32 is arranged on the punch 30, and the lower die 40 does not need to be arranged with additional air ducts and devices, simplifying the structure.
