Description

Technical Field

[0001] The present invention belongs to the technical field of die-cutting equipment, and particularly relates to an intelligent pressure-adjusting die-cutting system and method thereof. Background Art

[0002] The die-cutting process is a cutting technology for shaping materials, mainly used for precisely cutting sheet materials according to pre-designed shapes and sizes. The die-cutting process is usually achieved by combining a die-cutting knife (or die) with a pressure device. The die-cutting knife is generally a metal knife with a specific-shaped cutting edge, installed on a die-cutting plate (or die holder). When a pressure device (such as a die-cutting machine) applies pressure, the die-cutting knife cuts the material (such as paper, plastic film, leather, rubber, etc.) placed below it, separating the material according to the shape of the die, so as to obtain the required shape and size.

[0003] In the traditional die-cutting process, the pressure adjustment method mainly relies on manual rocker adjustment and means such as PET knife printing. This adjustment method has many disadvantages. Since the thickness and hardness of different materials vary, it is difficult to ensure the stability of pressure during production, which often leads to unstable cutting quality of products, such as intermittent cutting, seriously affecting product quality. Once there is an oversight in the self-inspection link, it is extremely easy to cause batch product abnormalities, bringing economic losses to the enterprise.

[0004] Combining the above problem entry points, it will be found that when the existing devices on the market are in use, it is very difficult to avoid the above-mentioned problems at the same time, so that the desired effect cannot be achieved. Therefore, we have proposed an intelligent pressure-adjusting die-cutting system and method that can pre-detect the thickness, hardness and elastic modulus of materials during use, flexibly adjust the die-cutting pressure according to the material characteristics, and dynamically adjust the die-cutting pressure during the die-cutting process to ensure the die-cutting quality of products. Summary of the Invention

[0005] The purpose of the present invention is to propose an intelligent pressure-adjusting die-cutting system and method thereof. The advantages are that by installing high-precision material characteristic sensors in the feeding area of the die-cutting machine to detect the thickness, hardness and elastic modulus of materials, the pressure control unit receives the data of the sensors, calculates the optimal die-cutting pressure parameters through a preset algorithm, and dynamically adjusts the pressure of the die-cutting head according to the instructions of the data analysis module to ensure that the most appropriate pressure can be applied to each batch of materials. At the same time, record the parameters of each die-cutting and the number of finished products, and continuously optimize the algorithm model through machine learning to achieve self-optimization of pressure adjustment, so as to realize the intelligent adjustment of die-cutting pressure, with the advantages of significantly reducing errors caused by human factors; improving die-cutting accuracy, reducing the rejection rate, and increasing material utilization rate; adapting to a wider range of material types and thicknesses, increasing production flexibility; continuously improving die-cutting efficiency and product quality through continuous learning and optimization.

[0006] The above technical object of the present invention is achieved by the following technical solutions: An intelligent pressure-adjusting die-cutting system includes a machine body. Guide frames are bolted to both the front and rear sides of the machine body. Fixed seats are bolted to both the top and bottom of the front guide frame, and material property sensors are bolted inside the fixed seats. In the middle of the top inside the machine body, a die-cutting assembly is bolted. On the front side of the right side of the machine body, a pressure control unit is bolted, and the pressure control unit is electrically connected to both the die-cutting assembly and the material property sensor respectively;

[0007] The die-cutting assembly includes a lower die base, which is bolted to the middle of the top inside the machine body. An upper die base is arranged on the top of the lower die base. A die-cutting die is bolted to the bottom of the upper die base, and two die blades are bolted to the bottom of the die-cutting die. A pressure sensor is bolted to the front side of the bottom of the upper die base. An installation plate is bolted to the top of the upper die base. A pressure adjustment module is arranged inside the machine body, and hydraulic columns are arranged at the four corners of the top of the pressure adjustment module. The top of the hydraulic column is bolted to the installation plate. Both the pressure adjustment module and the pressure sensor are electrically connected to the pressure control unit. Flattening assemblies are bolted to both the front and rear sides of the bottom of the installation plate. Positioning assemblies are bolted to both sides of the top of the machine body, and the positioning assemblies are used in cooperation with the upper die base and the lower die base respectively.

[0008] With the above technical solutions, in the feeding area of the die-cutting machine, a high-precision material property sensor detects the thickness, hardness and elastic modulus of the material. The pressure control unit receives the data from the material property sensor, calculates the optimal die-cutting pressure parameters through a preset algorithm, and dynamically adjusts the pressure of the die-cutting assembly according to the instructions of the data analysis module in the pressure control unit, ensuring that the most suitable pressure can be applied to each batch of materials. At the same time, the parameters of each die-cutting and the number of finished products are recorded, and the algorithm model is continuously optimized through machine learning to realize the self-optimization of pressure adjustment, so as to realize the intelligent adjustment of die-cutting pressure, significantly reduce the errors caused by human factors, improve the die-cutting accuracy, reduce the defective rate, improve the material utilization rate, adapt to a wider variety of materials and thicknesses, increase the production flexibility, and continuously improve the die-cutting efficiency and product quality through continuous learning and optimization.

[0009] The present invention is further set as: Clamping seats are bolted to both the front and rear sides of the surfaces of the upper die base and the lower die base, and the sides of the clamping seats close to the installation plate and the inner wall of the machine body are bolted to them respectively. A die-cutting groove for cooperating with the die blades is provided on the top of the lower die base.

[0010] With the above technical solutions, the clamping seats play a role in fixing the upper die base and the lower die base, ensuring the relative position stability of the two during the die-cutting process, and preventing the die from being displaced due to factors such as vibration, which affects the die-cutting accuracy.

[0011] The present invention is further configured as follows: The flattening assembly includes mounting blocks, which are respectively bolted to the front side and the rear side of the bottom of the mounting plate. Both sides of each mounting block are rotatably connected to a first fixing plate. A connecting plate is slidably arranged inside the first fixing plate, and a second fixing plate is sleeved on the surface of the connecting plate. An installation frame is rotatably connected between the bottoms of the two second fixing plates, and a flattening roller is rotatably connected inside the installation frame. Positioning plates are bolted to the opposite sides of the two first fixing plates and the two second fixing plates on the front side and the rear side. An adjusting spring is arranged between the opposite sides of the two positioning plates.

[0012] With the above technical solution, by setting the flattening assembly, when the upper die base descends, it will synchronously drive the mounting blocks and the first fixing plates to move downward. And due to the contact limitation between the flattening roller and the material, the flattening rollers on the front side and the rear side will move in opposite directions, so that the first fixing plates and the second fixing plates rotate, realizing the flattening process of the material by the flattening roller. And through the setting of the adjusting spring, by using the elasticity of the adjusting spring, the flattening roller can press against the material, and can also play a role in assisting the positioning of the material.

[0013] The present invention is further configured as follows: Stopping protrusions are arranged on both sides of the mounting block, and the stopping protrusions are used in cooperation with the first fixing plate.

[0014] With the above technical solution, by setting the stopping protrusions, the rotation path of the first fixing plate can be limited, so that it can only rotate in one direction, ensuring the movement track of the flattening roller.

[0015] The present invention is further configured as follows: Conveyor plates are bolted to the front side and the rear side inside the machine body, and the side of the conveyor plate close to the lower die base is in contact with it. The surface of the flattening roller is in rotational contact with the conveyor plate.

[0016] With the above technical solution, a stable conveying platform is provided for the material by the conveyor plate, ensuring that the material can smoothly pass through the die-cutting area during the die-cutting process.

[0017] The present invention is further configured as follows: The positioning assembly includes a fixed frame, which is bolted to both sides of the top of the machine body. A moving plate is arranged on the top of the fixed frame, and the side of the moving plate close to the upper die base is bolted to it. A plurality of push rods are bolted to the bottom of the moving plate. A fixed pipe is bolted inside the fixed frame, and a plurality of guiding cylinders are communicated with the top of the fixed pipe. The guiding cylinders correspond to the positions of the push rods and are used in cooperation with them. A fixed cylinder is bolted to the top of the inner wall of the fixed frame, and a pressing rod is slidably arranged inside the fixed cylinder. A positioning block is bolted to the bottom of the pressing rod. The fixed cylinder is communicated with the fixed pipe through a pipeline.

[0018] With the above technical solution, by setting the positioning component, when the upper die base moves downward, it will synchronously drive the moving plate and the push rod to move downward, so that the push rod enters the inside of the guiding cylinder and extrudes the hydraulic oil in the fixed pipe. Under the action of pressure, the hydraulic oil will enter the inside of the fixed cylinder and extrude the pressing rod and the positioning block to move downward, so that the positioning block positions the material, enabling the material to conform to the predetermined position and ensuring the die-cutting quality.

[0019] The present invention is further configured as follows: a return spring is provided at the bottom of the positioning block, and the bottom of the return spring is connected to the inner wall of the fixed frame, and the bottom of the positioning block is made of a flexible material.

[0020] With the above technical solution, by setting the return spring, when the upper die base moves upward, the pressure on the push rod will disappear. Therefore, the elasticity of the return spring can reset the pressing rod and the positioning block, and extrude the hydraulic oil in the fixed cylinder back into the fixed pipe, preparing for the next positioning operation.

[0021] The present invention is further configured as follows: two fixing frames are bolted to the front side and the rear side inside the machine body respectively. The fixing frames are in contact with the conveying plate on the side close to it. A fixing roller and a movable roller are rotatably connected between the opposite sides of the two fixing frames on both sides. Both sides of the movable roller are rotatably connected with adjusting blocks, and the adjusting blocks are slidably arranged inside the fixing frames.

[0022] With the above technical solution, through the setting of the fixing frames, the fixing roller and the movable roller, the material during the conveying process can be guided to ensure that the material remains in a stable state during the conveying process, preventing problems such as slack and deviation of the material, and the adjusting blocks can facilitate the adjustment of the distance between the movable roller and the fixing roller.

[0023] The present invention is further configured as follows: an adjusting screw rod is rotatably connected to the top of the adjusting block, and the top of the adjusting screw rod extends to the top of the fixing frame and is threadedly connected thereto.

[0024] With the above technical solution, through the cooperation of the adjusting block and the adjusting screw rod, the position of the movable roller can be flexibly adjusted according to the characteristics of the material such as thickness, so as to adapt to the conveying requirements of different materials, ensure the smooth progress of the entire die-cutting process, and improve production efficiency and product quality.

[0025] A method for using an intelligent pressure-adjusting die-cutting system includes the following steps:

[0026] S1. Guide the material to be die-cut into the die-cutting system. While conveying, the material characteristic sensor detects the characteristics of the material such as thickness, hardness and elastic modulus, and transmits the detected data to the pressure control unit in real time;

[0027] After the pressure control unit receives the data from the material property sensor, it calculates the die-cutting pressure parameters of the die-cutting component that are most suitable for the current material according to a preset algorithm. At the same time, the pressure sensor monitors the die-cutting pressure in real time and feeds the pressure data back to the pressure control unit, which dynamically adjusts the pressure of the die-cutting component according to the feedback information;

[0028] S3. When the die-cutting component performs die-cutting on the material, the positioning component positions the material at the die-cutting position to make it conform to the predetermined position, ensuring the die-cutting quality. At the same time, the flattening component adjusts the flatness of the material surface to prevent the die-cutting quality from decreasing due to the unevenness of the material.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. By the combined use of the die-cutting component, the material property sensor and the pressure control unit, the high-precision material property sensor detects the thickness, hardness and elastic modulus of the material in the feeding area of the die-cutting machine. The pressure control unit receives the data from the material property sensor, calculates the most suitable die-cutting pressure parameters through a preset algorithm, and dynamically adjusts the pressure of the die-cutting component according to the instructions of the data analysis module in the pressure control unit, ensuring that the most suitable pressure can be applied to each batch of materials. At the same time, the parameters of each die-cutting and the number of finished products are recorded, and the algorithm model is continuously optimized through machine learning to realize the self-optimization of pressure adjustment, thereby realizing the intelligent adjustment of die-cutting pressure, significantly reducing the errors caused by human factors; improving die-cutting accuracy, reducing the defective rate, and increasing the material utilization rate; adapting to a wider variety of materials and thicknesses, increasing production flexibility; continuously improving die-cutting efficiency and product quality through continuous learning and optimization;

[0031] 2. By setting the flattening component and the positioning component, the flattening component and the positioning component will be driven synchronously during the die-cutting process of the die-cutting component, so that the flattening component performs a comprehensive flattening process on the material, which can effectively solve the problem of unstable cutting quality caused by the unevenness of the material, such as uneven cutting, edge defects, etc. The positioning component ensures the precise positioning of the material during the die-cutting process, realizes the rapid and accurate adjustment of the material position, not only can avoid cutting errors caused by material deviation, greatly reduce the scrap rate, improve the product qualification rate, but also make the die-cutting process more efficient and orderly.

Detailed implementation manners

[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Embodiment 1:

[0042] Refer to Figures 1-3 , a die-cutting system with intelligent pressure adjustment, including a body 1, guiding frames 2 are bolted to both the front side and the rear side of the body 1, fixing seats 16 are bolted to both the top and the bottom of the front guiding frame 2, and a material property sensor 3 is bolted inside the fixing seat 16. A die-cutting component 4 is bolted to the middle of the inner top of the body 1, and a pressure control unit 5 is bolted to the front side of the right side of the body 1, and the pressure control unit 5 is electrically connected to both the die-cutting component 4 and the material property sensor 3;

[0043] The die-cutting assembly 4 includes a lower die base 41, which is bolted to the middle of the inner top of the machine body 1. A top die base 42 is arranged on the top of the lower die base 41. A die-cutting die 43 is bolted to the bottom of the top die base 42, and two die blades 44 are bolted to the bottom of the die-cutting die 43. A pressure sensor 45 is bolted to the front side of the bottom of the top die base 42. An installation plate 46 is bolted to the top of the top die base 42. A pressure adjustment module 47 is arranged inside the machine body 1, and hydraulic columns 48 are arranged at the four corners of the top of the pressure adjustment module 47. The top of the hydraulic column 48 is bolted to the installation plate 46. Both the pressure adjustment module 47 and the pressure sensor 45 are electrically connected to the pressure control unit 5. By the combined use of the die-cutting assembly 4, the material property sensor 3 and the pressure control unit 5, in the feeding area of the die-cutting machine, the high-precision material property sensor 3 detects the thickness, hardness and elastic modulus of the material. The pressure control unit 5 receives the data of the material property sensor 3, calculates the optimal die-cutting pressure parameters through a preset algorithm, and dynamically adjusts the pressure of the die-cutting assembly 4 according to the instruction of the data analysis module in the pressure control unit 5 to ensure that the most suitable pressure can be applied to each batch of materials. At the same time, record the parameters of each die-cutting and the number of finished products, and continuously optimize the algorithm model through machine learning to realize the self-optimization of pressure adjustment, so as to realize the intelligent adjustment of die-cutting pressure, significantly reduce the errors caused by human factors, improve the die-cutting accuracy, reduce the defective rate, improve the material utilization rate, adapt to a wider variety of materials and thicknesses, increase the production flexibility, and continuously improve the die-cutting efficiency and product quality through continuous learning and optimization.

[0044] As Figure 2 shown, clamping seats 8 are bolted to the front side and the rear side of the surfaces of the top die base 42 and the lower die base 41, and the sides of the clamping seats 8 close to the installation plate 46 and the inner wall of the machine body 1 are bolted to the two respectively. A die-cutting groove for cooperating with the die blade 44 is clamped on the top of the lower die base 41. The clamping seats 8 play a role in fixing the top die base 42 and the lower die base 41, ensuring the relative position stability of the two during the die-cutting process, and preventing the die from being misaligned due to factors such as vibration, which affects the die-cutting accuracy.

[0045] As Figure 3 shown, two fixing frames 11 are bolted to the front side and the rear side inside the machine body 1. The side of the fixing frame 11 close to the conveying plate 9 is in contact with it. A fixing roller 12 and a movable roller 13 are rotatably connected between the opposite sides of the two fixing frames 11 on both sides. Both sides of the movable roller 13 are rotatably connected with adjusting blocks 14, and the adjusting blocks 14 are slidably arranged inside the fixing frame 11. Through the arrangement of the fixing frame 11, the fixing roller 12 and the movable roller 13, the material during the conveying process can be guided to ensure that the material remains in a stable state during the conveying process, preventing problems such as the material being loose or offset, and the adjusting block 14 can facilitate the adjustment of the distance between the movable roller 13 and the fixing roller 12.

[0046] As Figure 3As shown in the figure, the top of the adjusting block 14 is rotatably connected to an adjusting screw rod 15, and the top of the adjusting screw rod 15 extends to the top of the fixing frame 11 and is threadedly connected thereto. Through the cooperation of the adjusting block 14 and the adjusting screw rod 15, the position of the movable roller 13 can be flexibly adjusted according to the characteristics such as the thickness of the material, so as to adapt to the conveying requirements of different materials, ensure the smooth progress of the entire die-cutting process, and improve production efficiency and product quality.

[0047] Brief description of the use process: The material to be die-cut is guided into the die-cutting system through the front guiding frame 2, and enters between the upper die base 42 and the lower die base 41 through between the fixed roller 12 and the movable roller 13. During the conveying process, the material property sensor 3 detects the properties such as the thickness, hardness and elastic modulus of the material, and transmits the detected data to the pressure control unit 5 in real time. After receiving the data from the material property sensor 3, the pressure control unit 5 calculates the die-cutting pressure parameters of the die-cutting assembly 4 most suitable for the current material according to the preset algorithm. Then, after receiving the instruction, the pressure adjustment module 47 controls the hydraulic column 48 to start moving and drives the upper die base 42 to move downward, so that the die-cutting die 43 and the die blade 44 perform die-cutting operations on the material. At the same time, the pressure sensor 45 will monitor the die-cutting pressure in real time and feedback the pressure data to the pressure control unit 5. The pressure control unit 5 performs real-time fine adjustment on the pressure adjustment module 47 according to the feedback data to ensure that the die-cutting pressure is stable within the most suitable parameter range.

[0048] Embodiment 2:

[0049] Reference Figures 4-6 As shown in the figure, leveling assemblies 6 are bolted to the front side and the rear side of the bottom of the mounting plate 46, and positioning assemblies 7 are bolted to both sides of the top of the machine body 1, and the positioning assemblies 7 are respectively used in cooperation with the upper die base 42 and the lower die base 41. By arranging the leveling assemblies 6 and the positioning assemblies 7, the leveling assemblies 6 and the positioning assemblies 7 will be driven to move synchronously during the die-cutting process of the die-cutting assembly 4, so that the leveling assemblies 6 perform all-round leveling treatment on the material, which can effectively solve the problem of unstable cutting quality caused by uneven material, such as uneven cutting, edge defects, etc. The positioning assembly 7 ensures the precise positioning of the material during the die-cutting process, realizes the rapid and accurate adjustment of the position of the material, not only can avoid cutting errors caused by material deviation, greatly reduce the waste rate, improve the product qualification rate, but also make the die-cutting process more efficient and orderly.

[0050] Such as Figure 4As shown, the flattening assembly 6 includes mounting blocks 61, which are bolted to the front and rear sides of the bottom of the mounting plate 46 respectively. First fixing plates 62 are rotatably connected to both sides of the mounting blocks 61. A connecting plate 63 is slidably arranged inside the first fixing plates 62, and a second fixing plate 64 is sleeved on the surface of the connecting plate 63. A mounting frame 65 is rotatably connected between the bottoms of the two second fixing plates 64, and a flattening roller 66 is rotatably connected inside the mounting frame 65. Positioning plates 67 are bolted to the opposite sides of the front and rear first fixing plates 62 and second fixing plates 64. An adjusting spring 68 is arranged between the opposite sides of the two positioning plates 67. By setting the flattening assembly 6, when the upper die base 42 descends, it will synchronously drive the mounting blocks 61 and the first fixing plates 62 to move downward. And due to the contact limitation between the flattening roller 66 and the material, the front and rear flattening rollers 66 will move in opposite directions. Therefore, the first fixing plates 62 and the second fixing plates 64 rotate, realizing the flattening process of the material by the flattening roller 66. And through the setting of the adjusting spring 68, by using the elasticity of the adjusting spring 68, the flattening roller 66 can press against the material, and can also play a role in assisting the positioning of the material.

[0051] As Figure 4 shown, stop protrusions are arranged on both sides of the mounting block 61, and the stop protrusions are used in cooperation with the first fixing plate 62. By setting the stop protrusions, the rotation path of the first fixing plate 62 can be limited, so that it can only rotate in one direction, ensuring the movement track of the flattening roller 66.

[0052] As Figure 1 shown, conveying plates 9 are bolted to the front and rear sides inside the machine body 1, and the side of the conveying plate 9 close to the lower die base 41 is in contact with it. The surface of the flattening roller 66 is in rotational contact with the conveying plate 9. The conveying plate 9 provides a stable conveying platform for the material, ensuring that the material can smoothly pass through the die-cutting area during the die-cutting process.

[0053] As Figure 6As shown in the figure, the positioning component 7 includes a fixed frame 71, which is bolted to both sides of the top of the machine body 1. A moving plate 72 is provided on the top of the fixed frame 71, and the side of the moving plate 72 close to the upper die base 42 is bolted to it. A number of push rods 73 are bolted to the bottom of the moving plate 72. A fixed pipe 74 is bolted inside the fixed frame 71, and a number of guide cylinders 75 are connected to the top of the fixed pipe 74. The guide cylinders 75 correspond to the push rods 73 in position and are used in cooperation with them. A fixed cylinder 76 is bolted to the top of the inner wall of the fixed frame 71, and a pressing rod 77 is slidably arranged inside the fixed cylinder 76. A positioning block 78 is bolted to the bottom of the pressing rod 77. The fixed cylinder 76 is connected to the fixed pipe 74 through a pipeline. By setting the positioning component 7, when the upper die base 42 moves downward, it will synchronously drive the moving plate 72 and the push rods 73 to move downward, so that the push rods 73 enter the inside of the guide cylinders 75 and squeeze the oil in the fixed pipe 74. Under the action of pressure, the oil will enter the inside of the fixed cylinder 76 and squeeze the pressing rod 77 and the positioning block 78 to move downward, so that the positioning block 78 positions the material, enabling the material to conform to the predetermined position and ensuring the die-cutting quality.

[0054] As Figure 6 shown, a return spring 10 is provided at the bottom of the positioning block 78, and the bottom of the return spring 10 is connected to the inner wall of the fixed frame 71. The bottom of the positioning block 78 is made of a flexible material. By setting the return spring 10, when the upper die base 42 moves upward, the pressure on the push rod 73 will disappear. Therefore, the elasticity of the return spring 10 can reset the pressing rod 77 and the positioning block 78, squeezing the oil in the fixed cylinder 76 back into the fixed pipe 74 to prepare for the next positioning operation.

[0055] Brief description of the use process: As the upper die base 42 descends, the leveling component 6 at the bottom of the mounting plate 46 moves downward synchronously, and the leveling roller 66 contacts the material on the conveying plate 9. As the first fixing plate 62 and the second fixing plate 64 move, the front and rear leveling rollers 66 will move in opposite directions. This movement causes the first fixing plate 62 and the second fixing plate 64 to rotate. At the same time, the elastic force of the adjusting spring 68 makes the leveling roller 66 always maintain a certain pressing force on the material, realizing the leveling treatment of the material. The stop protrusions on both sides of the mounting block 61 limit the rotation path of the first fixing plate 62, ensuring the stable movement track of the leveling roller 66 and guaranteeing the consistency of the leveling effect. When the upper die base 42 continues to move downward, the moving plate 72 and the push rods 73 move downward synchronously. The push rods 73 enter the inside of the guide cylinders 75 and squeeze the oil in the fixed pipe 74. Under the action of pressure, the oil enters the fixed cylinder 76 through the pipeline, squeezing the pressing rod 77 and the positioning block 78 to move downward. The flexible material at the bottom of the positioning block 78 contacts the surface of the material, accurately positioning the material to ensure that the material is in the predetermined die-cutting position.

[0056] As Figure 7As shown in the figure, the present invention also provides a method for using a die-cutting system with intelligent pressure adjustment, including the following steps:

[0057] S1. Guide the material to be die-cut into the die-cutting system. During transportation, the material property sensor 3 detects the properties of the material such as thickness, hardness, and elastic modulus, and transmits the detected data to the pressure control unit 5 in real time.

[0058] S2. After receiving the data from the material property sensor 3, the pressure control unit 5 calculates the die-cutting pressure parameters of the die-cutting component 4 that are most suitable for the current material according to a preset algorithm. At the same time, the pressure sensor 45 monitors the die-cutting pressure in real time and feeds back the pressure data to the pressure control unit 5. The pressure control unit 5 dynamically adjusts the pressure of the die-cutting component 4 according to the feedback information.

[0059] S3. When the die-cutting component 4 performs die-cutting on the material, the positioning component 7 positions the material at the die-cutting position to make it conform to the predetermined position, ensuring the die-cutting quality. At the same time, the leveling component 6 adjusts the flatness of the material surface to prevent the die-cutting quality from deteriorating due to the unevenness of the material.

[0060] This specific embodiment is only an explanation of the present invention and does not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
