Description

Technical Field

[0001] This invention relates to the field of printing and packaging technology, specifically to a die-cutting machine. Background Technology

[0002] A die-cutting machine is a device used to precisely cut, creasing, hot stamping, and other processing of materials such as paper, leather, plastic, and film. Its core function is to process materials into specific shapes or textures through the combination of molds and pressure. Flatbed die-cutting machines, based on processing requirements, fix customized die-cutting dies (such as steel dies or laser dies) on the upper or lower die base of the equipment. Positioning devices (such as photoelectric sensors or positioning pins) ensure the die and material are aligned to their preset positions. The upper die base is driven downwards via hydraulic, pneumatic, or mechanical transmission mechanisms, bringing the die into contact with the material and applying pressure. The die's cutting edge cuts the material, or a creasing die forms creases on the material surface. During feeding, the material's position must be ensured. Traditional die-cutting structures use several sets of horizontally adjustable and positioned guide structures for limiting movement, which is cumbersome to adjust. During unloading and waste removal, if separation is achieved via die rollers, some material may be difficult to detach from the waste. Using a downward-pressing detachment structure is affected by the tension of the waste's front and rear edges. If the waste's front and rear edges are tight, the edges may shrink during pressing, affecting subsequent material separation. If the waste's front and rear edges are loose, incomplete material removal during pressing is likely. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a die-cutting machine.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a die-cutting machine, comprising a machine body, wherein an loading platform and a unloading platform are respectively arranged on the front and rear sides of the machine body, and further comprising: The die-cutting assembly includes a lower die assembly, an upper die assembly, and a drive assembly. The lower die assembly is embedded in the middle part of the upper surface of the machine body. An upper die assembly that closes with the lower die assembly is provided above the machine body. Drive rods that pass through the four corners of the lower die assembly are provided at the four corners of the upper die assembly. A drive assembly that drives the four sets of drive rods to rise and fall is also provided inside the machine body. A vertical guide assembly is provided at the end of both the loading platform and the unloading platform away from the machine body; A horizontal guide assembly is also provided on the machine body for horizontally guiding materials. The material guiding assembly includes a feeding assembly, a discharging assembly, and a transfer assembly. A feeding assembly is mounted on the discharging platform to drive the discharging assembly to move back and forth. The discharging assembly includes a mounting plate, side plates, a top plate, a lifter, a pressure plate, a pre-tensioning plate, a buffer pad, a support plate, and support rollers. Side plates are symmetrically arranged on the left and right sides above the mounting plate. The top plate is positioned above the two sets of side plates.

Connecting holes adapted to the connecting rods are also provided on the pre-tensioning plate. The transfer assembly is positioned between the two sets of support plates. An output hole is provided on the side plate near the output end of the transfer assembly.

[0005] To facilitate the feeding of auxiliary materials, the present invention is improved in that the vertical guide assembly includes a roller frame, an upper roller and a lower roller, and the roller frame is provided on both the feeding platform and the unloading sleeve. The upper roller and the lower roller are rotatably arranged at the upper and lower ends of the roller frame.

[0006] Furthermore, to assist in material feeding, the present invention is improved in that the horizontal guiding component includes a centering device, a guide block, a guide shaft, and a pressure cap. Guide holes are symmetrically arranged at the left and right ends of the front and rear sides of the machine body. The machine body is also provided with a guide block that is slidably connected to the guide hole. A guide shaft is rotatably arranged on the guide block. A pressure cap is arranged on the guide shaft. The machine body is also provided with a centering device that drives the guide blocks located on the left and right sides to center.

[0007] To ensure that the guide blocks on the left and right sides move towards each other, the present invention is improved in that the centering device includes a cover, an auxiliary plate, a worm gear, a worm, a forward and reverse toothed rod, and a first motor. The cover and the auxiliary plate are respectively arranged on the left and right sides of the machine body. The worm and several sets of worm gears are arranged inside the cover. The worm meshes with the several sets of worm gears. Several sets of forward and reverse toothed rods are rotatably arranged between the auxiliary plate and the cover. The forward and reverse toothed rods pass through the cover and are connected to the center of the worm gear. The output end of the first motor passes through the cover and is connected to the worm. The guide block is threadedly connected to the forward and reverse toothed rod below.

[0008] Preferably, a sliding rod penetrating the top plate is provided above the pretensioning plate, and a spring connected to the pretensioning plate is provided below the top plate, with the spring sleeved around the sliding rod.

[0009] To facilitate material transfer, the present invention includes an improved material transfer assembly comprising a second motor, transfer rollers, and a conveyor belt. Several sets of transfer rollers are rotatably arranged between the two sets of support plates, and a conveyor belt is fitted onto the several sets of transfer rollers. The output end of the second motor passes through the support plate and is connected to one set of transfer rollers. A guide frame is also provided between the two sets of support plates, and the guide frame protrudes from the output hole.

[0010] To stabilize the front and rear position of the feeding assembly, the present invention improves upon this invention by including a screw, a third motor, a slide block, and auxiliary rods in the feeding assembly. A slide groove is provided on the feeding platform, positioned between the machine body and a vertical guide assembly located at the rear. The screw is rotatably mounted on both sides of the slide groove. Two sets of auxiliary rods are also provided on both sides of the slide groove, with the screw positioned between the two sets of auxiliary rods. The output end of the third motor passes through the feeding platform and is connected to the screw. The slide block is threadedly connected to the screw. Auxiliary holes adapted to the auxiliary rods are provided on both the left and right sides of the slide block. Bolts connected to the slide block are provided at the four corners of the mounting plate.

[0011] Preferably, the body is further provided with a scale bar, and the guide block is provided with a pointing block.

[0012] Preferably, the first motor, the second motor, and the third motor are all servo motors.

[0013] Preferably, the lifting device is a cylinder.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a die-cutting machine with the following advantages: This die-cutting machine guides the material feed through the collaboration of horizontal and vertical guide components. This solves the problem that the horizontal guide structure of traditional die-cutting machines requires manual adjustment of the guide components one by one, which is time-consuming and has low accuracy, and is prone to die-cutting misalignment due to guide deviation. The pre-tensioning plate is linked to the upper die assembly via a connecting rod. During die cutting, the upper die assembly descends, synchronously driving the pre-tensioning plate downwards. This causes the buffer pad to engage with the support roller, creating a uniform pre-tensioning force on the waste material and maintaining stable tension at its front and rear edges (neither too tight nor too loose). This "synchronous die cutting and pre-tensioning" design avoids the material stripping problem caused by tension fluctuations in traditional structures from the outset. The pressure plate is driven by a lifter and presses down the material precisely through the through holes of the pre-tension plate. With the support of the support roller, the material and waste are separated under stable tension, which significantly improves the thoroughness of descrambling. At the same time, the elastic cushioning effect of the buffer pad can avoid material deformation or waste tearing caused by hard pressure. The feeding component drives the unloading component to move back and forth, and the unloading position can be flexibly adjusted according to the length of the material. Together with the conveyor belt and guide frame of the transfer component, it realizes the rapid transfer and classified output of the die-cut material (the finished product is discharged through the output hole, and the waste is sent away by the transfer component), which solves the cumbersome process of unloading and waste separation in traditional equipment.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please refer to Figure 1- Figure 9A die-cutting machine includes a machine body 1, wherein a loading platform 2 and a unloading platform 3 are respectively arranged on the front and rear sides of the machine body 1, and further includes: The die-cutting assembly includes a lower die assembly 4, an upper die assembly 5, and a drive assembly 6. The lower die assembly 4 is embedded in the middle part of the upper surface of the machine body 1. The upper die assembly 5, which closes with the lower die assembly 4, is arranged above the machine body 1. The upper die assembly 5 has drive rods 7 that pass through the four corners of the lower die assembly 4. The machine body 1 is also equipped with a drive assembly 6 that drives the four sets of drive rods 7 to rise and fall. Lower die assembly 4: Embedded in the middle of the upper surface of the machine body 1, serving as a "reference platform" for die cutting. Its surface is fixed with a die-cutting die (steel die or indentation die) according to processing requirements. The position of the die cutting edge or indentation protrusion precisely corresponds to the preset pattern of the material to be processed. Upper die assembly 5: Located above the machine body 1, forming a mold-closing relationship with the lower die assembly 4. Its bottom surface is a flat pressing surface (or a corresponding clearance structure for the lower die). The drive rods 7 set at the four corners pass through the four corners of the lower die assembly 4, ensuring contact with the lower die during lifting and lowering. Verticality of component 4; Drive component 6: Built into the machine body 1, usually using a hydraulic cylinder or servo motor driven screw structure, which drives the upper die component 5 to descend / rise by synchronously controlling the lifting and lowering of four sets of drive rods 7: When descending, the upper die component 5 and the lower die component 4 close the die, and the die cuts the material or presses out creases by a preset pressure (adjusted according to the material hardness, usually 5-20 tons); When rising, the upper die component 5 resets, reserving operating space for the next die cutting. The equipment is used with intermittent unwinding component and intermittent winding component. The material is located between the upper die component 5 and the lower die component 4 to complete intermittent feeding. With the help of drive component 6, the upper die component 5 is intermittently driven to press down to complete the die cutting operation. During material feeding, the vertical guide assembly is provided at the end of the loading platform 2 and the unloading platform 3 away from the machine body 1. The vertical guide assembly is installed at the end of the loading platform 2 and the unloading platform 3 away from the machine body 1 and consists of a roller frame 17, an upper roller 18, and a lower roller 19. The roller frame 17 is fixed to the surface of the loading platform 2 / unloading platform 3. The upper roller 18 and the lower roller 19 are rotatably connected to the upper and lower ends of the roller frame 17, forming a "clamping" channel structure. The channel height is adjusted according to the material thickness (by adjusting the height of the upper roller 18 through the adjustment device on the roller frame 17). Its core function is to limit the material longitudinally (in the thickness direction): when the material (such as paper or film) enters the loading platform 2, it must first pass through the roller channel of the vertical guide assembly. The gravity or elastic pressure of the upper roller 18 (in some equipment, the upper roller 18) A spring 30 is installed at the shaft end to keep the material flat and avoid die-cutting misalignment caused by wrinkles; during feeding, the vertical guide component also flattens the processed material to prevent curling from affecting subsequent waste removal. The machine body 1 is also equipped with a horizontal guide assembly for guiding materials horizontally. This horizontal guide assembly, installed on the machine body 1, ensures accurate positioning of the material in the horizontal direction (width direction), solving the problem of cumbersome debugging in traditional guide structures. It consists of a centering device, guide block 20, guide shaft 21, and pressure cap 22. In actual use, guide holes are symmetrically arranged at the left and right ends of the front and rear sides of the machine body 1. The guide block 20 is slidably connected to the guide hole, and the guide shaft 21 rotatably arranged on its top is parallel to the material feeding direction. The surface of the shaft is covered with a wear-resistant rubber layer (to avoid scratching the material). The two sets of guide shafts 21 form a "left and right clamping" channel. The channel width matches the material width. The centering device consists of a cover 23, an auxiliary plate 24, and... The worm gear 25, worm 26, forward and reverse toothed rods 27, and first motor 28 constitute the core drive structure for achieving "automatic centering": the cover 23 and auxiliary plate 24 are fixed to the left and right sides of the machine body 1, respectively. The worm 26 inside meshes with multiple sets of worm gears 25, and each set of worm gears 25 is connected to a set of forward and reverse toothed rods 27 (passing through the cover 23 and auxiliary plate 24). The guide block 20 is threadedly connected to the forward and reverse toothed rods 27 below. When the first motor 28 drives the worm 26 to rotate, the worm gears 25 synchronously drive the forward and reverse toothed rods 27 to rotate, causing the guide blocks 20 on the left and right sides to move in opposite directions along the guide holes, thereby quickly adjusting the width of the guide shaft 21 channel to adapt to materials of different widths. In conjunction with the scale strip on the machine body 1 and the pointing block 39 on the guide block 20, precise and visual adjustment of the guide width is achieved. The pressure cap 22 is located above the guide shaft 21 and serves to help limit the material movement; In this embodiment, the material guiding assembly includes a feeding assembly, a discharging assembly, and a material transfer assembly. The discharging platform 3 is equipped with a feeding assembly that drives the discharging assembly to move back and forth. The discharging assembly includes a mounting plate 8, side plates 9, a top plate 10, a lifter 11, a pressure plate 12, a pre-tensioning plate 13, a buffer pad 14, a support plate 15, and a support roller 16. Side plates 9 are symmetrically arranged on the left and right sides above the mounting plate 8. The top plate 10 is arranged above the two sets of side plates 9. The output end of the lifter 11 passes through the top plate 10 and the pre-tensioning plate 13 and is connected to the pressure plate 12. Support plates 15 are also symmetrically arranged on the front and rear sides of the mounting plate 8. The support roller 16 is rotatably mounted on the support plate 15. A buffer pad 14 is located above the support roller 16 below the pre-tensioning plate 13. The pre-tensioning plate 13 has through holes adapted to the pressure plate 12. The upper mold assembly 5... Connecting rods 41 are symmetrically arranged on the left and right sides of the rear side. The pre-tightening plate 13 is also provided with connecting holes adapted to the connecting rods 41. The material transfer assembly is arranged between the two sets of support plates 15. The side plate 9 near the output end of the material transfer assembly is provided with an output hole. The feeding assembly includes a screw 35, a third motor 36, a slide 37, and auxiliary rods 38. The screw 35 and two sets of auxiliary rods 38 are arranged in the groove on the unloading platform 3. The slide 37 is threadedly connected to the screw 35 and limited by the auxiliary rods 38. When the third motor 36 drives the screw 35 to rotate, the slide 37 drives the unloading assembly to move back and forth along the groove so as to ensure that the buffer pad 14 and the support roller 16 of the unloading assembly can press the front and rear edges of the waste. The mounting plate 8 is connected to the slide 37 by bolts 40. The left and right side plates 9 of the mounting plate 8 support the top plate. The top plate 10 forms a frame structure. The pre-tensioning plate 13 is located below the top plate 10 and is slidably connected to the top plate 10 via a slide rod 29. The spring 30 on the periphery of the slide rod 29 applies a downward pre-tensioning force to the pre-tensioning plate 13. The buffer pad 14 (rubber material, hardness 50-60 Shore A) below the pre-tensioning plate 13 cooperates with the support roller 16 to form a "flexible clamping" for the waste material. The pre-tensioning plate 13 is connected to the connecting rod 41 on the rear side of the upper die assembly 5 through the connecting hole to achieve "synchronous die cutting and pre-tensioning"—when the upper die assembly 5 descends, the connecting rod 41 drives the pre-tensioning plate 13 to descend synchronously. The buffer pad 14 and the support roller 16 cooperate to apply uniform pressure to the waste material, ensuring stable tension at the front and rear edges of the waste material (neither too tight nor too loose). Then, the output end of the lifting device 11 passes through the top plate 10 and the pre-tensioning plate 13 and connects to the pressure plate 12. The pressure plate 12 can pass through the pre-tensioning plate 13. The through hole moves up and down to press the finished product off the waste. The elevator 11 resets, and the pre-tightening plate 13 resets along with the upper mold assembly 5, thus completing the stable separation of the material and the waste. The elevator 11 uses a cylinder with a fast response. The material transfer assembly consists of a second motor 31, a material transfer roller 32, a conveyor belt 33, and a guide frame 34. The material transfer roller 32 between the two sets of support plates 15 is connected by the conveyor belt 33. When the second motor 31 drives the material transfer roller 32 to rotate, the conveyor belt 33 transports the separated waste material backward. The guide frame 34 is located between the two sets of support plates 15 and protrudes from the output hole of the side plate 9. It is used to guide the finished product from the output hole to the collection box.

[0019] In this embodiment, the first motor 28, the second motor 31 and the third motor 36 are all servo motors with precise control. It should be noted that there is a gap between the connecting rod 41 and the vertical guide assembly located at the rear. After removing the bolt 40, the feeding assembly with the material transfer assembly can be replaced. When changing the corresponding material, the feeding assembly and material transfer assembly of the corresponding specifications can be selected for assembly.
