Description

Technical Field

[0001] This invention relates to the field of die-cutting equipment technology, and in particular to an automatic die-cutting and waste removal machine for cardboard. Background Technology

[0002] In the production of cardboard packaging products, die-cutting and waste removal is a crucial process. It typically involves feeding printed or unprinted cardboard into a die-cutting machine, using a die to cut out a specific shape of forming sheet, and separating the forming sheet from surrounding waste. Traditional die-cutting and waste removal equipment has room for improvement in automation and processing precision: Firstly, in the feeding and cutting stages, material conveying relies heavily on continuous or intermittent mechanical transmission, making it difficult to accurately position each sheet of material entering the cutting station. Accumulated errors or slippage can easily lead to cutting position deviations, resulting in material waste or substandard product dimensions. Therefore, the industry urgently needs an integrated device that can achieve high-precision automatic feeding and positioning, stable and reliable cutting, and efficient automated waste removal to improve production efficiency, material utilization, and product consistency. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an automatic die-cutting and waste removal machine for cardboard.

[0004] The technical solution adopted by this invention to solve its technical problem is: This invention provides an automatic die-cutting and waste removal machine for cardboard, including a feeding mechanism and a cutting mechanism, which are used for feeding and cutting materials, respectively; it also includes a fixed-distance conveying module and a separation module for use in conjunction with the cutting mechanism, the cutting mechanism is used to cut the material after it has been conveyed at a fixed distance by the fixed-distance conveying module, and the separation module is used to separate the formed material board cut by the cutting mechanism from the waste material; The fixed-distance conveying module includes a material sensor and a first driving component for use with the material sensor. The material sensor is used to detect the displacement or position status information of the material, and the first driving component is used to control the conveying stroke of the material according to the detection result of the material sensor, so that the material completes the cutting process in a controlled movement state in the cutting mechanism. Thus, without increasing the reserved area at the edge of the material, it can be used with the separation module to separate the formed material plate from the waste material, thereby improving the utilization rate of the material.

[0005] Preferably, the fixed-distance conveying module further includes a first frame, on which a first roller is provided. The length of the first roller is greater than the width of the material, and a material sensor is detachably mounted on the first roller. The first frame is also equipped with a second roller and a third roller, with a gap between the second roller and the third roller for material to pass through. The first drive unit drives the second roller to rotate, thereby moving the external material. It can accurately detect the position of the material and achieve stable and reliable fixed-distance clamping and conveying. This ensures that the material is accurately positioned when it enters the cutting station, effectively avoiding cutting errors caused by material deviation or slippage, and ensuring the consistency and reliability of subsequent die-cutting processes.

[0006] Preferably, the second roller is provided with first bearings at both ends in the length direction, and the second roller is rotatably mounted to the first frame via the first bearings; The first frame is provided with a first groove, and the fixed-distance conveying module also includes a block and a first limiting member for limiting the block. The block is housed in the first groove, and a second bearing is provided on the block. The third roller is rotatably set with the block via the second bearing. The first frame is detachably equipped with a first plate, and a first limiting member is screwed onto the first plate. A third groove is formed on the block near the end of the first limiting member. The end of the first limiting member near the block is accommodated in the third groove, which is used to limit the displacement of the block along the axial direction of the third roller. The second roller is stably rotated by using a first bearing. Combined with the block that can be accommodated in the first groove, the second bearing, and the axial limiting structure composed of the first plate and the first limiting member, it can ensure the flexible rotation of the third roller while facilitating quick adjustment and locking of its installation position. This allows for flexible and convenient adjustment of the conveying gap according to the material thickness, enhances the equipment's adaptability to materials of different specifications, and simplifies maintenance and debugging operations.

[0007] Preferably, the first frame is further provided with a protrusion located in the first groove, the protrusion being used to limit the displacement of the block along the axial direction of the third roller; A second groove is provided on the block, and an elastic element is provided inside the second groove. The elastic element has two working ends, which are used to abut against the groove arm of the second groove and the first plate respectively. By setting a protrusion in the first groove to limit the block axially, and setting an elastic element in the block, it can provide a constant clamping force to the third roller while allowing it to have a certain elastic buffer space in the vertical direction. This achieves flexible clamping of materials (especially materials with uneven surfaces), which can ensure the stability of conveying and avoid damage to the material surface due to excessive clamping, thereby improving the adaptability and safety of the conveying process.

[0008] Preferably, a fixed-distance conveying module is disposed between the feeding mechanism and the cutting mechanism, and a first feeding module is also disposed between the cutting mechanism and the separation module. The first feeding module is used to transfer materials at a predetermined distance. A first transfer module is also disposed on the side of the cutting mechanism away from the feeding mechanism. The first transfer module is used to transfer the material cut by the cutting mechanism to the separation module for separation. The first transfer module includes a second frame and a plurality of fourth rollers rotatably disposed on the second frame. There is a clearance between two adjacent fourth rollers for the falling of the separated forming plate. The separation module includes a first support mounted on a second frame and a second drive unit detachably mounted on the first support. The output end of the second drive unit is equipped with a material plate. The second drive unit is used to drive the material plate closer to or further away from the first transfer module, thereby separating the cut shaped material plate from the waste through the material plate. This ensures that while smoothly transferring the cut material, it actively and reliably separates the shaped material plate from the waste mechanically, thus achieving automation and high efficiency of the separation action. It avoids the lag and omissions of manual separation, ensures the complete collection of the shaped material plate and the timely removal of waste, and guarantees the continuity and cleanliness of the production line.

[0009] Preferably, the second frame is provided with a first rail and a rod, and a sliding block is rotatably provided on the fourth roller. The sliding block is slidably disposed on the first rail. The rod is provided with a fourth groove for the passage of an external second limiting member. The second limiting member passes through the fourth groove and the rod is used to limit the sliding block. A second feeding module is provided at the end of the second frame away from the cutting mechanism. The second feeding module is used to transfer the waste material separated from the forming plate to an external collection bin. The position and size of the clearance between each transfer roller can be flexibly and accurately adjusted according to the material size or separation requirements, thereby realizing the customized configuration of the separation station, optimizing the falling trajectory of forming plates of different sizes and the waste support effect, and further improving the versatility and separation accuracy of the separation module.

[0010] Preferably, the feeding mechanism includes a third transfer module and a guiding mechanism. The third transfer module includes a third frame and a transmission roller rotatably mounted on the third frame. The third frame is also provided with a drive motor for driving the transmission roller to rotate. The guiding mechanism includes a shaft component mounted on the third frame and a guide plate detachably mounted on the shaft component. The length direction of the shaft component is parallel to the length direction of the transmission roller, and the length direction of the guide plate intersects the length direction of the shaft component. The guide plate is located above the transmission roller and at the end of the transmission roller in the width direction. Both ends of the guide plate in the length direction are provided with bent portions, which are formed by bending from the end of the guide plate in the length direction to the end of the transmission roller in the length direction. By using a transmission roller driven by a drive motor to form the main conveyor line, and setting a guide plate with a specific bent portion on its upper side, the material from the feeding end is efficiently transported and automatically aligned in the width direction. This achieves the effect of pre-correcting the material before it enters the precision processing area, effectively preventing lateral deviation of the material during long-distance transport, and laying a good alignment foundation for subsequent fixed-distance cutting.

[0011] Preferably, a fifth groove is provided at the end of the guide plate closer to the drive roller in the width direction, the fifth groove is used to accommodate the drive roller, and a bent portion is provided at the end of the guide plate away from the drive roller in the width direction; The bottom of the guide plate is provided with a slider that is slidably mounted on the shaft component. The slider is provided with a limiting hoop and a third limiting component for adjusting the limiting hoop. The third limiting component is used to fasten the limiting hoop to the shaft component or to detach it from the shaft component. The guide plate has two parts, and the shaft is equipped with a third driving component for moving the two guide plates closer or further apart. By setting a slider, a limiting clamp and a third limiting component at the bottom of the guide plate, and configuring a third driving component that can drive the two guide plates to move synchronously towards or away from each other, the installation height, angle and distance between the two plates can be adjusted and locked in a multi-dimensional and precise manner. This enables the optimal guiding channel to be quickly and accurately adjusted for materials of different widths and thicknesses, greatly enhancing the process adaptability and adjustment convenience of the feeding mechanism.

[0012] Preferably, the feeding mechanism further includes a loading mechanism, which is located on the side of the third transfer module away from the cutting mechanism. The loading mechanism includes a second support mounted on the third frame, on which a beam and a picking device mounted on the beam are slidably mounted. The second support is also provided with a fourth driving component for driving the beam and the picking device on the beam to move closer to or away from the third transfer module. By setting the beam with the picking device, driven by the fourth driving component, to slide on the second support, the stacked materials are picked up one piece at a time and smoothly and transferred to the starting end of the third transfer module, thereby realizing automated loading from the material pile to the conveyor line, replacing manual placement. This not only improves the loading efficiency and rhythm stability, but also reduces labor intensity and the risk of human error.

[0013] Preferably, the feeding mechanism further includes a third support mounted on the third frame, the third support being provided with a fifth roller and a fifth driving member for driving the fifth roller to rotate, and the third support also being provided with a sixth roller, the sixth roller being detachably provided with a roller for cooperating with the fifth roller to transfer materials. The feeding mechanism also includes a material lifting module and a seventh roller mounted on a third support. The seventh roller is detachably equipped with a first baffle and a second baffle. The first baffle and the second baffle work together with the material lifting module to limit the middle and ends of the material, respectively. By configuring the fifth roller driven by the fifth drive unit, the sixth roller with rollers, and the seventh roller with a pair of baffles (first baffle and second baffle), and working in conjunction with the material lifting module, the mechanism plays a role in initially sorting and guiding the material before it enters the main conveyor line, and effectively limiting the middle and edges of the material. This ensures that the material enters the guiding and conveying stage in a flat and centered manner, avoiding misalignment, skewing or jamming when the material is stacked, and ensuring the continuity and reliability of automated feeding.

[0014] The beneficial effects of this invention are as follows: through the coordinated operation of the feeding mechanism and the cutting mechanism, combined with the fixed-distance conveying module located therebetween, the material sensor is used to detect the material in real time, and the first driving component drives the material to achieve fixed-distance conveying, ensuring that the material is accurately cut at the predetermined position of the cutting mechanism, thereby maximizing the utilization of the material. At the same time, the separation module efficiently separates the cut molding plate from the waste material, playing a role in automating the control of material conveying, positioning, cutting and waste removal, thereby achieving the technical effects of improving the precision of die-cutting, reducing material waste, enhancing production efficiency and reducing manual intervention.

[0026] Reference Figures 1 to 12An automatic die-cutting and waste removal machine for cardboard includes a feeding mechanism 1 and a cutting mechanism 2, which are used for feeding materials and cutting materials, respectively; it also includes a fixed-distance conveying module 3 and a separation module 4 for use in conjunction with the cutting mechanism 2, the cutting mechanism 2 is used to cut the materials after being conveyed at a fixed distance by the fixed-distance conveying module 3, and the separation module 4 is used to separate the formed material board cut by the cutting mechanism 2 from the waste material; The fixed-distance conveying module 3 includes a material sensor 10 and a first driving member 32 for use with the material sensor 10. The material sensor 10 is used to detect the displacement and / or position status information of the material. The first driving member 32 is used to control the conveying stroke of the material according to the detection result of the material sensor 10, so that the material completes the cutting process in the cutting mechanism 2 in a controlled movement state. Thus, without increasing the reserved area at the edge of the material, it cooperates with the separation module 4 to separate the formed material plate from the waste material, thereby improving the utilization rate of the material.

[0027] With the above-described structure, during use, the material feeding mechanism 1 and the cutting mechanism 2 work together, and the fixed-distance conveying module 3 located between them uses the material sensor 10 to detect the material in real time. The first driving component 32 drives the material to achieve fixed-distance conveying, ensuring that the material is accurately cut at the predetermined position of the cutting mechanism 2, maximizing the utilization of the material. At the same time, the separation module 4 efficiently separates the cut molding plate from the waste material, playing a role in automating the material conveying, positioning, cutting and waste removal. This achieves the technical effects of improving the precision of die-cutting, reducing material waste, enhancing production efficiency and reducing manual intervention.

[0028] It is worth noting that the material is cardboard, and the length of the cardboard is at least no shorter than the length of the cutting mechanism 2.

[0029] Material sensor 10 is a photoelectric sensor / proximity switch, and multiple material sensors 10 are provided.

[0030] Specifically, the fixed-distance conveying module 3 also includes a first frame 30, on which a first roller 31 is fixedly mounted. The length of the first roller 31 is greater than the width of the material, and the material sensor 10 is detachably mounted on the first roller 31. The first frame 30 is also rotatably equipped with a second roller 321 and a third roller 322, which are in cooperation with each other. A gap is formed between the second roller 321 and the third roller 322 for material to pass through. The first drive member 32 drives the second roller 321 to rotate and move the external material. It can accurately detect the position of the material and achieve stable and reliable fixed-distance clamping and conveying. This ensures that the position of the material is highly accurate when it enters the cutting station, effectively avoids cutting errors caused by material deviation or slippage, and ensures the consistency and reliability of subsequent die-cutting processes.

[0031] The first roller 31 is located at the bottom of the material, or it can be located above the material. The material sensor 10 is located at the end of the second roller 321 away from the feeding mechanism 1.

[0032] When the material sensor 10 does not detect any material, the first drive unit 32 drives the second roller 321 to rotate continuously at a low speed. Here, low speed means that when the second roller 321 rotates to convey material, the displacement rate of the material is less than the displacement rate of the material when the third transfer module 7 rotates to convey material. When the material is sandwiched between the second roller 321 and the third roller 322, the displacement of the material is only controlled by the first drive unit 32.

[0033] The material sensor 10 is detachably mounted on the first roller body 31 via a quick-release assembly.

[0034] The diameter of the second roller 321 is larger than the diameter of the third roller 322.

[0035] The material sensor 10 is provided in two sets, each set including at least two material sensors 10. The two sets are respectively located on both sides of the second roller 321. Both sets of material sensors 10 are located on the material conveying path. The first set of material sensors 10, which is close to the side where the material flows into the separation module 4, is used to initially determine whether there is material. When the presence of material is determined, the first drive unit 32 controls the second roller 321 to rotate at an initial speed. When the second set senses the passage of material, it can accelerate the conveying.

[0036] Specifically, the second roller body 321 is provided with a first bearing 301 at both ends in the length direction, and the second roller body 321 is rotatably connected to the first frame body 30 via the first bearing 301; The first frame 30 is provided with a first groove 302. The fixed-distance conveying module also includes a block 33 and a first limiting member 351 for limiting the block 33. The block 33 is housed in the first groove 302. The block 33 is provided with a second bearing 331. The third roller 322 is rotatably set with the block 33 via the second bearing 331. A first plate 35 is detachably mounted on the first frame 30. A first limiting member 351 is screwed onto the first plate 35. A third groove 333 is formed on the block 33 near the end of the first limiting member 351. The end of the first limiting member 351 near the block 33 is accommodated in the third groove 333, which is used to limit the displacement of the block 33 along the axial direction of the third roller 322. The second roller 321 is stably rotated by using a first bearing 301. Combined with the block 33 that can be accommodated in the first groove 302, the second bearing 331, and the axial limiting structure composed of the first plate 35 and the first limiting member 351, it can ensure the flexible rotation of the third roller 322 while facilitating quick adjustment and locking of its installation position. This enables flexible and convenient adjustment of the conveying gap according to the material thickness, enhances the equipment's adaptability to materials of different specifications, and simplifies maintenance and debugging operations.

[0037] The first groove 302 is approximately rectangular and is formed on the first frame 30. The block 33 is a rectangular block that is slidably accommodated in the first groove 302. The first plate 35 is set on the first frame 30 by external bolts.

[0038] The first limiting member 351 includes a screwing part for screwing and a rod part provided on the screwing part. The end of the rod part near the screwing part is threaded, and the rod part is screwed to the first plate 35 via the thread. The end of the rod part with the thread is also provided with a fastening nut. The end of the rod part away from the screwing part is a cylinder with a smooth outer surface, which is used to accommodate the block 33 in the third groove 333 to limit the block 33.

[0039] Specifically, the first frame 30 is also provided with a protrusion 303 located in the first groove 302, the protrusion 303 is used to limit the displacement of the block 33 along the axial direction of the third roller 322; A second groove 332 is provided on the block 33. An elastic element 34 is provided inside the second groove 332. The elastic element 34 has two working ends. The two working ends of the elastic element 34 are used to abut against the groove arm of the second groove 332 and the first plate 35, respectively. By setting a protrusion 303 in the first groove 302 to limit the block 33 axially, and setting an elastic element 34 in the block 33, it can provide a constant clamping force to the third roller 322 while allowing it to have a certain elastic buffer space in the vertical direction. This achieves flexible clamping of materials (especially materials with uneven surfaces), which can ensure the stability of conveying and avoid damage to the material surface due to excessive clamping, thereby improving the adaptability and safety of the conveying process.

[0040] The first plate 35 may be provided with the same second groove 332.

[0041] The second groove 332 is located at the end of the block 33 away from the first bearing 301, and the elastic element 34 is a spring with one end located in the second groove 332.

[0042] In this embodiment, the first frame 30, the first bearing 301, the first groove 302, the protrusion 303, the block 33, the second bearing 331, the second groove 332, the third groove 333, the elastic element 34, the first plate 35, and the first limiting element 351 are arranged in two sets. The two sets are located at both ends of the first bearing 301, the second roller 321, and the third roller 322 in the length direction and are located between the feeding mechanism 1 and the cutting mechanism 2 and between the cutting mechanism 2 and the separating module 4. The two protrusions 303 are located at the ends of the two first frames 30 that are far apart and are used to limit the corresponding blocks 33 in the direction that the two first frames 30 are far apart.

[0043] Specifically, the fixed-distance conveying module 3 is located between the feeding mechanism 1 and the cutting mechanism 2. A first feeding module is also provided between the cutting mechanism 2 and the separation module 4. The first feeding module is used to transfer materials according to a predetermined distance. A first transfer module 5 is also provided on the side of the cutting mechanism 2 away from the feeding mechanism 1. The first transfer module 5 is used to transfer the material cut by the cutting mechanism 2 to the separation module 4 for separation. The first transfer module 5 includes a second frame 51 and a plurality of fourth rollers 52 rotatably mounted on the second frame 51. There is a clearance between two adjacent fourth rollers 52 for the falling of the separated forming plate. The separation module 4 includes a first support 41 mounted on the second frame 51 and a second drive unit 42 detachably mounted on the first support 41. The output end of the second drive unit 42 is provided with a material plate 43. The second drive unit 42 is used to drive the material plate 43 to approach or move away from the first transfer module 5, so as to separate the cut shaped material plate from the waste through the material plate 43. This ensures that while the cut material is transferred smoothly, the shaped material plate and the waste are mechanically separated actively and reliably. This achieves automation and high efficiency of the separation action, avoids the lag and omission of manual separation, ensures the complete collection of the shaped material plate and the timely removal of waste, and ensures the continuity and cleanliness of the production line.

[0044] The first feeding module has the same structure as the fixed-distance conveying module 3, except that it does not have a material sensor 10. The material sensor 10 can be used in conjunction with the first driving component 32 in the first feeding module and the second feeding module described below to control the material.

[0045] At least one material plate 43 is provided between two adjacent fourth roller bodies 52. The material plate 43 can be inclined relative to the output end of the second drive member 42, so as to realize the gradual separation of the forming material plate from the waste material from point to ring.

[0046] For example, the separation module 4 can cut the molded material plate and the waste material into half to form a half connection, and the other half can be completely separated. The material plate 43 first separates the half connection.

[0047] Specifically, the second frame 51 is provided with a first rail 53 and a rod 531, the fourth roller 52 is rotatably provided with a sliding block 521, the sliding block 521 is slidably disposed on the first rail 53, the rod 531 is provided with a fourth groove 532, the fourth groove 532 is used for the external second limiting member 522 to pass through, the second limiting member 522 passes through the fourth groove 532 and the rod 531 is screwed with the sliding block 521 to limit the sliding block 521; The second frame 51 is equipped with a second feeding module at the end away from the cutting mechanism 2. The second feeding module is used to transfer the waste material separated from the forming plate to the external collection bin. The position and size of the clearance between each transfer roller can be flexibly and accurately adjusted according to the material size or separation requirements, thereby realizing the customized configuration of the separation station, optimizing the falling trajectory of forming plates of different sizes and the waste support effect, and further improving the versatility and separation accuracy of the separation module 4.

[0048] The second feed module has the same structure as the first feed module.

[0049] The fourth groove 532 has three strips, and the number of fourth grooves 532 is equal to the number of fourth rollers 52.

[0050] The second limiting member 522 has a threaded end near the sliding block 521, and a screw-on part is provided at the end away from the sliding block 521.

[0051] The bottom of the first transfer module 5 is also provided with a second transfer module 6, which is used to transfer and collect the falling molding plate.

[0052] Specifically, the feeding mechanism 1 includes a third transfer module 7 and a guiding mechanism 8. The third transfer module 7 includes a third frame 71 and a transmission roller 72 rotatably mounted on the third frame 71. The third frame 71 is also equipped with a drive motor for driving the transmission roller 72 to rotate. The guiding mechanism 8 includes a shaft component 81 mounted on the third frame 71 and a guide plate 82 detachably mounted on the shaft component 81. The length direction of the shaft component 81 is parallel to the length direction of the transmission roller 72, and the length direction of the guide plate 82 intersects the length direction of the shaft component 81. The guide plate 82 is located above the transmission roller 72 and at the end of the transmission roller 72 in the width direction. Both ends of the guide plate 82 in the length direction are provided with bent portions. The bent portions are formed by bending from the end of the guide plate 82 in the length direction to the end of the transmission roller 72 in the length direction. By using the transmission roller 72 driven by the drive motor to form the main conveyor line, and setting the guide plate 82 with specific bent portions on its upper side, it plays a role in efficiently transmitting materials from the feeding end and automatically centering them in the width direction at the same time. This realizes that the materials are pre-corrected before entering the precision processing area, effectively preventing lateral deviation of materials during long-distance transportation, and laying a good alignment foundation for subsequent fixed-distance cutting.

[0053] The material is placed on the drive roller 72 for displacement driven by the drive motor.

[0054] Specifically, a fifth groove 821 is provided at the end of the guide plate 82 closest to the transmission roller 72 in the width direction. The fifth groove 821 is used to accommodate the transmission roller 72. A bent portion is provided at the end of the guide plate 82 away from the transmission roller 72 in the width direction. The bottom of the guide plate 82 is provided with a slider 83 that is slidably disposed on the shaft member 81. The slider 83 is provided with a limiting hoop 84 and a third limiting member 85 for adjusting the limiting hoop 84. The third limiting member 85 is used to fasten the limiting hoop 84 to the shaft member 81 or to detach it from the shaft member 81. Two guide plates 82 are provided, and a third driving component 86 is also provided on the shaft component 81 for the two guide plates 82 to move closer or further apart. By setting a slider 83, a limiting clamp 84 and a third limiting component 85 at the bottom of the guide plate 82, and configuring a third driving component 86 that can drive the two guide plates 82 to move synchronously towards or away from each other, the installation height, angle and distance between the two guide plates 82 can be adjusted and locked in a multi-dimensional and precise manner. This enables the optimal guiding channel to be quickly and accurately adjusted for materials of different widths and thicknesses, greatly enhancing the process adaptability and adjustment convenience of the feeding mechanism 1.

[0055] The limiting clamp 84 and the third limiting member 85 constitute a quick-release assembly.

[0056] The third drive component 86 is disposed on one of the guide plates 82, and the third drive component 86 is also provided with a quick-release assembly. The third drive component 86 can be detachably disposed on the shaft component 81 via the quick-release assembly.

[0057] Of course, an elastic film layer, such as a silicone sleeve or a rubber sleeve, can be installed on the roller body.

[0058] Specifically, the feeding mechanism 1 also includes a loading mechanism 9, which is located on the side of the third transfer module 7 away from the cutting mechanism 2. The loading mechanism 9 includes a second support 91 mounted on the third frame 71. A beam 92 and a picking member 93 mounted on the beam 92 are slidably mounted on the second support 91. The second support 91 is also provided with a fourth driving member 910 for driving the beam 92 and the picking member 93 mounted on the beam 92 to move closer to or away from the third transfer module 7. By setting the beam 92 with the picking member 93, driven by the fourth driving member 910, to slide on the second support 91, the stacked materials are picked up one piece at a time and smoothly and transferred to the starting end of the third transfer module 7, thereby realizing automated loading from the material pile to the conveyor line, replacing manual placement. This not only improves the loading efficiency and rhythm stability, but also reduces labor intensity and the risk of human error.

[0059] The material handling component 93 is a suction cup connected to an external negative pressure generating component.

[0060] Specifically, the feeding mechanism 9 also includes a third support 94 mounted on the third frame 71. The third support 94 is provided with a fifth roller 942 and a fifth driving member 941 for driving the fifth roller 942 to rotate. The third support 94 is also provided with a sixth roller 943. The sixth roller 943 is detachably provided with a roller 944, which is used in conjunction with the fifth roller 942 to transfer materials. The feeding mechanism 9 also includes a material lifting module and a seventh roller 95 mounted on a third support 94. The seventh roller 95 is detachably equipped with a first baffle 96 and a second baffle 97. The first baffle 96 and the second baffle 97 are used in conjunction with the material lifting module to limit the middle and end of the material, respectively. By configuring the fifth roller 942 driven by the fifth drive unit 941, the sixth roller 943 with rollers 944, and the seventh roller 95 with a pair of baffles (first baffle 96 and second baffle 97), and in coordination with the material lifting module, it plays a role in initially sorting and guiding the material before it enters the main conveyor line, and effectively limiting the middle and edge of the material. This ensures that the material enters the guiding and conveying stage in a flat and centered manner, avoiding misalignment, skewing or jamming when the material is stacked, and ensuring the continuity and reliability of automated feeding.

[0061] The second support 91 is mounted on the third frame 71 via the third support 94.

[0062] The lifting module can be implemented using cylinders, hangers, etc.

[0063] Unlike traditional die-cutting waste removal methods that rely on pre-reserved areas at the edges of materials for positioning or gripping, this invention controls the overall displacement of the material through a fixed-distance conveying module 3. This ensures that the material's position is locked and stable when it enters the cutting mechanism 2 and the separation module 4. Since the separation of the forming plate and the waste material occurs under controlled material displacement, there is no need to increase the pre-reserved area at the edges of the material to achieve gripping or positioning. This improves the effective utilization rate of materials while ensuring the reliability of waste removal.

Any methods or structures that are similar to or identical to those of the present invention, or any technical deductions or substitutions made based on the concept of the present invention, should be considered within the scope of protection of the present invention.
