Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically a die-cutting machine that automatically adjusts the cutting size. Background Technology

[0002] Existing die-cutting machines, especially small and medium-sized flatbed or roller die-cutting machines, usually require complex manual adjustments when cutting products of different sizes. This operation is not only time-consuming and labor-intensive, reducing production efficiency, but also increases the purchase and management costs of molds, making it difficult to adapt to the flexible production needs of small batches and multiple varieties.

[0003] An existing patent (authorization announcement number: CN223251753U) discloses an automatic adjustable die-cutting machine. The key technical point of the solution is: through an adjustment mechanism, under the action of pressing a set of pressing rods and the compression action of springs, the movable rod can move along the path of the sliding groove. When the pressing rods are released, the movable rod is locked into one end of the sliding groove, and at the same time, the locking block moves into the locking groove. Then, the motor is started, and under the rotation of the motor output shaft, the first bevel gear is driven, causing the second bevel gear meshing with it to rotate, which drives the pressing rod and the threaded rod to rotate together, thereby driving a set of movable rods to move to the cutting position corresponding to the product. It is not necessary to place the product in a specific position in advance, which reduces the product placement requirements, improves the product cutting efficiency, and ensures the cutting accuracy.

[0004] However, the above technical solutions still have certain defects. The entire cutting process lacks intelligent visual feedback. It cannot automatically identify and compensate for patterns, markings or slight positional deviations on the material. During high-speed or long-distance production, it is easy to generate a large number of waste products due to accumulated errors. At the same time, it cannot be guaranteed that the cut material can be unloaded after cutting, causing intact materials to flow away with the waste. Therefore, a die-cutting machine with automatic adjustment of cutting size is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a die-cutting machine that automatically adjusts the cutting size to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A die-cutting machine with automatic adjustable cutting size includes a frame, on which the following components are sequentially arranged along the material conveying direction: Transmission assembly used for conveying uncut materials; Conveying assembly for conveying the cut material; Detection components are used to identify the location or characteristics of materials; Adjustment components are mounted on the frame; The adjustment assembly includes a support rod fixedly mounted on the frame, a first linear drive mechanism fixedly mounted on the support rod, a second linear drive mechanism fixedly mounted on the moving part of the first linear drive mechanism, and a die cutter mounted on the moving part of the second linear drive mechanism. The die cutter includes an airbag fixedly installed on the side of the moving part. A connecting pipe is fixedly provided on the outside of the airbag. A nozzle is fixedly connected to the side of the connecting pipe away from the airbag. A rotator is also provided on the side of the airbag on the moving part. A die-cutting device is installed below the rotator. The die-cutting device includes a bracket and a cutting width adjustment mechanism. The cutting width adjustment mechanism includes a driving component, a bidirectional screw driven by the driving component, a guide rod arranged parallel to the bidirectional screw, and two cutting heads respectively threaded to two sets of reverse threaded sections of the bidirectional screw.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: As a further embodiment of this utility model: the detection component includes a support leg fixedly mounted on a frame, a guide rail provided on the support leg, a sliding block slidably mounted on the guide rail, and an image acquisition device provided on the sliding block.

[0008] As a further improvement of this utility model: the image acquisition device is a CCD camera, and the CCD camera is equipped with a supplementary light.

[0009] As a further improvement of this utility model: the conveying assembly includes a conveyor belt driven by a second motor, and a fixed frame is provided inside the conveyor belt for support.

[0010] As a further embodiment of this utility model: the transmission assembly includes an unwinding roller and a transmission roller for driving the material forward, and a smoother for smoothing the material is also provided on the frame, and the transmission roller is driven by a second motor.

[0011] As a further improvement of this utility model: the smoother is provided in two sets, located at the discharge end of the transmission assembly and the feed end of the die cutter, respectively.

[0012] As a further improvement of this utility model, a collection box is provided in the frame below the discharge end of the conveying component and can be pulled out.

[0013] As a further improvement of this invention, the spray direction of the nozzle is toward the cutting area.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a die cutter, allows for adjustment of the cutting width during the die-cutting process and enables oblique or specific angle cutting. After cutting, small pieces of waste material may adhere to the die edge or the material itself, failing to be completely removed. As production continues, this adhered waste material can accumulate and potentially jam the die or damage the material. High-pressure airflow can effectively blow away this potentially sticky waste material, preventing jamming.

[0015] 2. This utility model, by setting an adjustment component, can make full-range adjustments to the die cutter along the x and y axes. No matter where the pattern to be cut is on the material surface, it can be accurately reached. When the detection component detects that the material is laterally deviated during conveying, the system can immediately instruct the first-stage mechanism to move for real-time tracking and compensation, thus solving the problem of batch scrap caused by material deviation.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figures 1-6 As shown, an automatic adjustable die-cutting machine includes a frame 1. Along the material conveying direction, the frame 1 is sequentially equipped with: a transmission assembly 2 for conveying uncut material; a conveying assembly 3 for conveying cut material; a detection assembly 5 for identifying the position or characteristics of the material; and an adjustment assembly 6 installed on the frame 1. In this embodiment, the transmission component 2 is activated to stably transport the raw material to be cut from the unwinding end to the processing area. The conveying component 3 is located after the cutting area and is responsible for continuing to transport the finished or semi-finished material that has been cut forward to the collection point. When the material flows under the detection component 5, the material is quickly scanned and photographed. The detected image data is transmitted to the machine's control system in real time. When the adjustment component 6 moves the die-cutting head to the target position, the die-cutting head falls to complete a precise cut.

[0020] In one embodiment, as shown in the figure, the transmission assembly 2 includes an unwinding roller 22 and a transmission roller 24 for driving the material forward. The frame 1 is also equipped with a smoother 25 for smoothing the material. The transmission roller 24 is driven by a second motor 31. There are two sets of smoothers 25, located at the discharge end of the transmission assembly 2 and the feed end of the die cutter 64, respectively. The unwinding roller 22 serves as a support source for the material. It is not driven by itself to maintain the tension of the material. It is driven by the transmission roller 24 to generate traction force to move the material. The first set of smoothers 25 performs the first leveling immediately after the material leaves the transmission roller 24. Its function is to eliminate wrinkles or uneven local stress that may be generated in the material under the traction of the transmission roller 24. The second set of smoothers 25 performs the second leveling before the material is about to enter the die-cutting area. Its function is to ensure that the material is in an absolutely flat and taut state when it reaches the bottom of the die cutter 64. The flat and tensioned material will not have its surface patterns or markings twisted or displaced. This enables the detection component 5 to capture clear, undistorted images, thereby enabling faster and more accurate identification and positioning, and improving the control precision of the entire system from the source.

[0021] In one embodiment, as shown in the figure, the conveying assembly 3 includes a conveyor belt 33 driven by a second motor 31. A fixing frame 32 is provided inside the conveyor belt 33 for support. A collection box 4 is provided in the frame 1 below the discharge end of the conveying assembly 3 and can be pulled out. The conveyor belt 33 is driven by the second motor 31 and supported by the fixing frame 32. When the die-cut material is sent to the discharge end by the conveyor belt 33, the finished product will fall into the collection box 4 at the bottom and be collected by the collection box 4.

[0022] In one embodiment, as shown in the figure, the detection component 5 includes a support leg 51 fixedly mounted on a frame 1. A guide rail 52 is mounted on the support leg 51, and a sliding block 53 is slidably mounted on the guide rail 52. An image acquisition device 54, which is a CCD camera, is mounted on the sliding block 53 and is equipped with a supplementary light 55. The support leg 51 supports the guide rail 52, and the position of the sliding block 53 can be manually adjusted, thus moving the image acquisition device 54. This facilitates the handling of production tasks involving wide materials or markers with variable positions. The supplementary light 55 provides stable illumination for the CCD camera. The supplementary light 55 ensures that the pattern on the material surface exhibits high contrast, facilitating accurate camera recognition.

[0023] In one embodiment, as shown in the figure, the adjustment assembly 6 includes a support rod 61 fixedly mounted on the frame 1. A first linear drive mechanism 62 is fixedly mounted on the support rod 61, and a second linear drive mechanism 63 is fixedly mounted on the moving part of the first linear drive mechanism 62. A die-cutter 64 is mounted on the moving part of the second linear drive mechanism 63. The first linear drive mechanism 62 is fixedly mounted on the support rod 61. When it is working, its moving part moves linearly along a preset direction, and the second linear drive mechanism 63 is fixed on the moving part of the first-stage drive mechanism. When it is activated, its moving part moves in another direction perpendicular to the first-stage movement direction, and the die-cutter 64 is finally mounted on the moving part of the second-stage drive mechanism. Therefore, it integrates the movement capabilities in two directions. Through the coordinated control of the two drive mechanisms by the central control system, the die-cutter 64 can be directed to move to any specified two-dimensional coordinate point (X,Y) within its movement range.

[0024] In one embodiment, as shown in the figure, the die cutter 64 includes an air bladder 641 fixedly installed on the side of the moving part. A connecting pipe 642 is fixedly disposed on the outside of the air bladder 641. A nozzle 643 is fixedly connected to the side of the connecting pipe 642 away from the air bladder 641. The spray direction of the nozzle 643 is towards the cutting area. The connecting pipe 642 serves as an airflow channel, reliably delivering compressed air from the air bladder 641 to the end effector, and spraying the gas towards the cutting area through the nozzle 643. During the die cutting process, tiny debris and dust are generated. If these debris fall on the material surface or the mold, it will cause indentations on the product during the next cut. The air blown by the nozzle 643 can promptly blow away these debris, ensuring that each cut is clean. At the same time, during the cutting process, the finished product may stick to the material after cutting and not be removed in time. Blowing air onto it can also assist in the demolding of the finished product and avoid material jamming.

[0025] In one embodiment, as shown in the figure, a rotator 644 is also provided on one side of the airbag 641 on the moving part. A die-cutting device is installed below the rotator 644. The die-cutting device includes a bracket 645 and a cutting width adjustment mechanism. The cutting width adjustment mechanism includes a drive member 646, a bidirectional screw 647 driven by the drive member 646, a guide rod 648 arranged parallel to the bidirectional screw 647, and two cutting heads 649 respectively threaded to two sets of opposite threaded sections of the bidirectional screw 647. The rotator 644 is mounted on the moving part and is itself an independent motion axis. The cutting heads 649 can not only perform straight cutting, but also oblique or specific angle cutting. The drive member 646 drives the bidirectional screw 647 to rotate, and the two cutting heads 649 will simultaneously move closer to each other or simultaneously move away from each other. The guide rod 648 is arranged parallel to the bidirectional screw 647 to prevent the cutting heads 649 from rotating with the screw. By controlling the number of rotations and direction of the drive member 646, the final distance between the two cutting heads 649 can be precisely controlled.

[0026] The above embodiment discloses an automatic adjustable cutting size die-cutting machine. When the transmission component 2 is activated, the unwinding roller 22 releases the rolled material, which is actively pulled by the transmission roller 24 to form a stable material flow. During its journey, the material passes through two sets of flatteners 25 at the beginning and end, effectively flattening it and eliminating internal stress, ensuring it enters the processing area in a flat, wrinkle-free state. The flat material enters below the detection component 5. A CCD camera mounted on the sliding block 53 of the guide rail 52, assisted by a supplementary light 55, scans the material to accurately identify its edge positions. The first linear drive mechanism 62 drives the entire crossbeam to move laterally (X-axis), while the second linear drive mechanism 63 drives the die-cutter 64 to move longitudinally (Y-axis). Together, they quickly position the die-cutter 64 directly above the target position. Simultaneously with the movement and positioning of the die-cutter 64, its internal cutting width adjustment mechanism begins to operate. The drive unit 646 drives the bidirectional screw 647 to rotate, causing the two cutting heads 649 to move synchronously towards or away from each other along the guide rod 648, automatically adjusting to the cutting width set in the program. The airbag 641 and the nozzle 643 spray airflow to blow away dust and debris in the cutting area, preparing for high-quality cutting. At the same time, it can assist in unloading the cut finished products. The cut finished products are continued to be conveyed forward by the conveying component 3 and enter the collection box 4.

[0027] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
