Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a clothing cloth cutting machine which can turn at multiple angles and avoid uneven cutting edges. Background Art

[0002] Multi-axis motion platforms are widely used in fabric shaping and cutting to achieve multi-angle cutting. By combining multi-dimensional movement of the fabric (e.g., along the X and Y axes) with the rotational adjustment of the cutting tool, the cutting head can automatically perform multi-angle cutting. This technology is primarily used in applications such as apparel manufacturing, home furnishings, and industrial fabric processing, aiming to improve cutting efficiency and precision through automation.

[0003] In existing technology, cutting tools typically use rollers to achieve efficient coordination with multi-axis motion platforms. This design uses a lifting cylinder to control the roller's contact with the fabric. Combined with an ultrasonic structure beneath the roller, the roller generates high-frequency vibrations as it rotates, achieving rolling cutting of the fabric. However, while this design meets the basic requirements for multi-angle cutting, it exhibits the following shortcomings in practical applications:

[0004] 1. Rolling deformation causes uneven edges of ultrasonic cutting: During the rolling cutting process, the roller tool will inevitably exert additional tension on the fabric due to the rolling motion. The cutting part melted under the action of ultrasonic high frequency will recrystallize and harden the edge, causing the fabric to roll and deform at the cutting part, thus forming an uneven cutting edge, which seriously affects the cutting effect.

[0005] 2. Unable to efficiently control the coordination of direction adjustment and cutting: The direction adjustment of roller cutting depends on the rotation of the roller. During the cutting process, the relative movement of the fabric and the roller cannot be paused or dynamically coordinated synchronously. Small errors in direction adjustment can easily cause fabric cutting deviations, further reducing cutting accuracy.

[0006] 3. Limited cutting speed and multi-angle adaptability: In the roller cutting method, in order to avoid the aggravation of rolling deformation, the cutting speed often needs to be controlled within a low range; and when the multi-axis motion platform is used for complex fabric cutting, the single motion characteristics of the roller are also difficult to quickly adapt to the needs of multi-angle changes.

[0007] To address the issues with roller cutting, the industry has experimented with non-roller cutting mechanisms, such as using the up-and-down motion of a blade instead of roller cutting. However, while these methods rely on skilled labor, manual operation lacks flexibility for multi-angle cutting, making them difficult to meet the demands of complex cutting scenarios. They also suffer from low cutting efficiency and fail to effectively control the uneven edges of ultrasonically cut parts.

[0008] Therefore, how to achieve multi-angle cutting with efficient cooperation with a multi-axis motion platform and at the same time effectively avoid uneven edges of ultrasonic welding has become a technical problem to be solved by the present utility model. Utility Model Content

A non-rolling cutting structure is used in synchronization with the multi-axis motion platform to achieve rapid response and efficient cutting during the multi-dimensional movement of the fabric.

[0032] 2. When fabric is sandwiched between the cutting blade and the transducer support platform and ultrasonic vibration cutting is performed, the directional adjustment movements of the multi-axis motion platform and the rotary lifting head are both suspended, avoiding additional tension on the fabric due to directional adjustment during the cutting process. This design ensures the stability of the cutting direction during the cutting stage, so that the fabric is evenly stressed in the cutting area, thereby effectively avoiding the generation of uneven edges due to ultrasonic melting. In addition, after the cutting blade and the transducer support platform are separated from the fabric, the multi-axis motion platform and the rotary lifting head resume the directional adjustment movement, achieving efficient connection to the next multi-angle cutting task.

[0033] 3. Through the multi-angle adjustment function of the rotating lifting head, the cutting punch can flexibly adapt to any angle requirement of the multi-axis motion platform, ensuring the efficiency of the fabric cutting process.

[0034] 4. By misaligning the cutting blade with the center of the transducer support platform and rotating the transducer support platform during the cutting process, the cutting blade impacts multiple locations on the support platform in sequence, effectively avoiding rapid wear caused by long-term impact on a single location and significantly extending the service life of the equipment. In addition, this rotation method ensures a more even distribution of wear during the cutting process, improving the stability and long-term reliability of the equipment.

[0060] Example 1:

[0061] In the scenario of automated shaping and cutting of fabrics, such as the cutting of high-tech fabrics such as Lycra fabrics in the garment manufacturing industry, the fabrics need to be cut in a complex multi-angle manner, and the cut edges must be smooth without any unevenness of the melt-cut edges to ensure high-quality finished products. In this process, the traditional roller cutting method often causes unevenness of the ultrasonic melt-cut edges 31 due to rolling deformation, while the simple up and down motion cutting method cannot meet the requirements of efficient multi-angle cutting. For example, see Figure 8 and Figure 9 , Figure 8 It is a schematic structural diagram of the melting edge 31 in a three-dimensional state. Figure 9 for Figure 8 The schematic structural diagram of the orthographic projection of the left side shows that in this state, the undulation of the fused edge 31 makes the stacked thickness of the fused edge 31 at the position close to the fused edge 31 greater than the thickness of the non-fused edge 31 on the clothing fabric 11, that is, the rolling deformation described in the present invention causes the undulating structure of the ultrasonic fused edge 31. Therefore, in response to this actual demand, the present embodiment provides a clothing fabric cutting machine for avoiding the undulation of the ultrasonic fused edge and realizing multi-angle cutting.

[0062] This garment fabric cutting machine includes a multi-axis motion platform 3, a rotary lift head 5, a cutting blade 6, an ultrasonic transducer assembly 7, and an elastic pressure cover mechanism. Its core feature is that by combining the multi-dimensional movement of the multi-axis motion platform 3 with the multi-angle adjustment function of the rotary lift head 5, coupled with the non-rolling cutting and ultrasonic vibration technology of the cutting blade 6, it solves the problems of low multi-angle cutting efficiency and insufficient control of uneven cut edges in existing technologies.

[0063] In a specific application scenario, the cloth to be cut is fixed flatly on the multi-axis motion platform 3. The cutting process is achieved through the following steps:

[0064] 1. Fabric Positioning and Preparation: The fabric is positioned on a multi-axis motion platform 3, which can perform multi-dimensional movement in the X and Y axes based on the input cutting path data. The cutting head bracket 4 is fixed to the garment fabric cutting machine frame 2, providing stable support for the multi-angle adjustment of the cutting blade 6.

[0065] 2. Cutting head adjustment and contact cutting: During the cutting process, the rotary lifting head 5 drives the second gear 14 and the first gear 12 to rotate forward or reverse through the motor 13, driving the cutting punch 6 to adjust the angle, so that the cutting punch 6 can cooperate with the multi-axis motion platform 3 to have more angles that can be adjusted. In addition, the ultrasonic transducer assembly 7 is activated. When the cutting punch 6 contacts the surface of the fabric, the transducer support platform 8 is precisely aligned with the blade end of the cutting punch 6, and cutting is performed using the high-frequency vibration of the ultrasonic wave. In an extended embodiment, the directional adjustment movement of the multi-axis motion platform 3 and the rotary lifting head 5 can be paused to ensure that the force direction of the fabric in the cutting area is stable and not affected by additional tension, thereby avoiding the generation of uneven edges caused by ultrasonic melting.

[0066] Furthermore, during the cutting process, especially when complex paths or turns are involved, in order to avoid overly obvious or prominent edges and corners in the cutting area, this embodiment increases the cutting density, that is, adopts a path planning with small and dense steps, so that the cutting punch 6 completes the cutting action with a finer step length during the cutting process. This optimization method can make the turning area smoother and more natural, further improving the cutting accuracy and the quality of the finished product. The above technology belongs to an extended implementation method known to ordinary technicians in this field, and is usually achieved by adjusting the step length parameter or path density in the control system. Its specific implementation method can be flexibly adjusted according to the characteristics of the fabric and the complexity of the path, and all belong to an extended implementation method known to ordinary technicians in this field.

[0067] 3. Cutting completion and subsequent adjustment: When the cutting punch 6 completes the cutting of a certain cutting path and leaves the transducer support platform 8, the rotary lifting head 5 resumes the direction adjustment capability and works in conjunction with the multi-axis motion platform 3 to prepare to complete the cutting task of the next path.

[0068] 4. Demonstration of technical effects: In actual operation, through the above design and process, the clothing fabric cutting machine significantly improves cutting efficiency and quality:

[0069] Avoiding uneven edges caused by ultrasonic melting: Due to the non-rolling cutting structure of the cutting punch 6 combined with ultrasonic vibration, the fabric is not subjected to tension caused by direction changes during the cutting process, thereby avoiding uneven edges caused by ultrasonic melting.

[0070] Achieve multi-angle precise cutting: The combination of the rotary lifting head 5 and the multi-axis motion platform 3 enables complex cutting paths to be completed efficiently without the need for repeated angle adjustment.

[0071] Improve cutting efficiency: The mechanism of pausing the direction adjustment movement ensures the precise coordination of the cutting action and the movement of the fabric, significantly shortening the cutting time.

[0072] For example, when cutting a piece of high-tech fabric, a variety of complex cutting angles are planned based on the cutting path. Traditional roller cutting methods can result in noticeable uneven edges on the fabric surface, and can even cause accumulated external forces to push and pull the fabric, resulting in waste. In this embodiment, however, the cutting blade 6 uses ultrasonic high-frequency vibrations to complete the cut each time it contacts the fabric. Pausing the movement for directional adjustments ensures a completely flat surface, resulting in a smooth, finished edge that meets process requirements.

[0073] Example 2:

[0074] In the manufacturing of high-end apparel, two pieces of fabric must be spliced ​​and bonded simultaneously during the cutting process. The resulting splice maintains a smooth appearance and avoids uneven edges. Furthermore, efficient multi-angle cutting is required. This embodiment further illustrates the specific implementation of the ultrasonic transducer assembly 7, multi-axis motion platform 3, and cutting control mechanism. The operational steps and technical effects are described in detail, based on actual application scenarios.

[0075] Implementation of Ultrasonic Transducer Assembly 7: In this embodiment, the ultrasonic transducer assembly 7 utilizes an ultrasonic transducer well known to those skilled in the art. It generates high-frequency vibrations through an ultrasonic vibrator, transmitting the vibration energy to the cutting edge of the cutting blade 6, thereby utilizing the micro-cutting properties of the high-frequency vibrations to cut the fabric. This assembly is fixedly mounted on the frame 2, with the transducer support platform 8 positioned directly below the cutting blade 6. Its top is precisely aligned with the cutting edge of the cutting blade 6 via a clearance hole 16, ensuring stable and efficient vibration cutting.

[0076] Implementation of Multi-Axis Motion Platform 3: Multi-axis motion platform 3 is a well-known platform in the art, capable of multi-dimensional planar motion. Once the fabric is positioned on the surface of multi-axis motion platform 3, it can precisely move along the X and Y axes according to the input path data, aligning with the cutting action of cutting blade 6 and enabling complex path cutting operations.

[0077] Dynamic adjustment mechanism of cutting control: When the cutting blade 6 is cutting the fabric, the cutting control system automatically suspends the direction adjustment movement of the multi-axis motion platform 3 and the rotary lifting head 5 to ensure the stability of the cutting direction; when the cutting blade 6 is separated from the fabric, the system resumes the direction adjustment function to ensure cutting efficiency and smoothness.

[0078] The operation process and specific implementation steps are as follows:

[0079] 1. Fabric Loading and Positioning: The fabric is clamped and positioned on the plane of the multi-axis motion platform 3 using a method known to those skilled in the art, such as edge or multi-angle clamping. During the clamping process, the fabric's flatness is ensured. Simultaneously, the cutting path data is input into the control system. Input of the cutting path data is accomplished through the control system's programming interface, which is an extended implementation known to those skilled in the art. For example, the control system can receive a cutting path file (e.g., a path diagram in DXF format) generated by computer-aided design (CAD) or clothing design software and, through a path parsing module, decompose the cutting path into XY-axis movement instructions for the multi-axis motion platform and angle adjustment instructions for the rotary lift head. For example, when cutting a piece of fabric with a complex lace design, a user can draw the cutting outline of the lace in the design software and upload the path file to the control system. The system then automatically parses the cutting path and converts it into a specific motion trajectory, including the simultaneous linear and curved movement of the template multi-axis motion platform and the angle adjustment of the cutting blade. This path data input method is commonly used in automated cutting equipment. It not only improves cutting accuracy and flexibility, but also makes the execution of complex cutting tasks more efficient and can adapt to the personalized processing needs of various fabrics.

[0080] 2. Dynamic coordination of cutting process:

[0081] Cutting starts: the cutting punch 6 is driven by the rotating lifting head 5 to descend to the surface of the fabric, the ultrasonic transducer assembly 7 is started, and the high-frequency vibration is transmitted to the fabric through the blade end of the cutting punch 6 to realize the micro-cutting operation.

[0082] Motion Pause: When the cutting blade 6 contacts the fabric, the XY-axis movement of the multi-axis motion platform 3 and the directional adjustment of the rotary lift head 5 are both paused. Due to the pause in directional adjustment, the forces acting on the fabric within the cutting area remain stable, preventing tension from changes in direction, thereby effectively preventing uneven edges during ultrasonic welding. Regarding the implementation of "motion pause," this embodiment employs, for example, a technical solution based on sensor detection and control logic. This is an extended implementation known to those skilled in the art. For example, when the cutting blade descends and contacts the fabric, the contact status between the cutting blade, the fabric, and the transducer support platform can be monitored in real time using, for example, a pressure sensor or position sensor 30. The location and mounting method of the sensor 30 are also known to those skilled in the art. These extended implementations are sufficient to achieve this effect. For example, the cutting blade 6 can be fixedly connected to the rotary lift head 5 via the sensor 30. Furthermore, when the sensor 30 detects the start of cutting, the control system immediately sends a signal to pause the XY-axis movement of the multi-axis motion platform and the directional adjustment of the rotary lift head. At this point, the system enters stable cutting mode, ensuring constant directional force in the cutting area and preventing uneven edges caused by excessive tension on the fabric due to motion adjustments. After the cutting action is completed, sensor 30 detects that the cutting blade has disengaged from the fabric, and the control system resumes normal motion of the multi-axis motion platform and rotary lift head to execute the next cutting task. For example, when cutting a complex curve, the multi-axis motion platform pauses at the current curve position. After the cutting blade completes the cut, the platform resumes motion and continues on to the next path, ensuring high cutting precision and stable force on the fabric.

[0083] Cutting is completed: the cutting punch 6 is separated from the fabric after completing the task of the current cutting path, and the system automatically resumes the movement of the multi-axis motion platform 3 and the direction adjustment function of the rotary lifting head 5 to prepare for the cutting task of the next path.

[0084] 3. Implementation of the Dynamic Adjustment Mechanism: System Monitoring and Response: The contact status between the cutting blade 6 and the transducer support platform 8 is monitored by a pressure sensor. When the pressure sensor detects that the fabric is being clamped, the control system immediately pauses the directional adjustment movement. Once the pressure sensor detects that the cutting blade 6 is separated from the fabric, the control system resumes the directional adjustment movement.

[0085] Example 3:

[0086] To extend the life of the equipment and improve cutting accuracy, this embodiment further optimizes the coordination between the cutting blade 6 and the transducer support platform 8. Specifically, while the blade end of the cutting blade 6 is still facing the transducer support platform 8, it is not directly aligned with the center of the transducer support platform 8. When the cutting blade 6 is cutting, the transducer support platform 8 is in a rotating state, allowing the blade end of the cutting blade 6 to sequentially punch multiple different positions on the transducer support platform 8, avoiding long-term impact on a single position during the cutting process, thereby effectively reducing the impact on the service life of the ultrasonic transducer assembly 7 due to single-point wear.

[0087] This rotation is achieved by:

[0088] 1. Rotation structure of ultrasonic transducer assembly 7: The main body of ultrasonic transducer assembly 7 is rotatably matched with the frame 2 via two or more bearings 28 , so that the transducer support platform 8 can be rotated under the drive of the ultrasonic transducer assembly 7 .

[0089] 2. Rotational Drive Mechanism: A first gear 24 is sleeved on the outside of the ultrasonic transducer assembly 7. A transducer rotation motor 25 is fixedly mounted on the frame 2. A second gear 26, which mates with the first gear 24, is fixedly mounted on the motor shaft of the transducer rotation motor 25. The first gear 24 and the second gear 26 are meshed and connected via a toothed belt 27. When the motor shaft of the transducer rotation motor 25 rotates, it drives the first gear 24 to rotate, thereby driving the transducer support platform 8 of the ultrasonic transducer assembly 7 to rotate. In a preferred embodiment, the transducer support platform 8 can be circular in shape.

[0090] Furthermore, during the rotation of the transducer support platform 8, the rotation can be performed before the cutting blade 6 contacts the fabric, that is, the transducer support platform 8 rotates during the non-cutting contact phase. This avoids deviations in impact during the cutting process and ensures that the blade end of the cutting blade 6 contacts the transducer support platform 8 at a different point during each cut, thereby evenly distributing wear and further extending the service life of the ultrasonic transducer assembly 7.

[0091] This solution effectively avoids the wear problem of a single contact point in traditional technology through a rotary drive method, optimizes the service life and stability of the equipment, and improves the accuracy of the cutting process. Especially when dealing with high-precision or high-intensity cutting requirements, it can ensure the long-term stable operation of the equipment.
