Description

Technical Field

[0001] This utility model relates to the field of die-cutting manufacturing technology, and in particular to a simple hand-tearable knife holder fixture for a circular knife machine. Background Technology

[0002] In the die-cutting manufacturing field, rotary die-cutting machines, as a highly efficient and continuous cutting device, are widely used in the processing of materials such as paper, film, and tape. Their core technology is based on a high-speed rotating circular blade, achieving continuous cutting through precise contact with the material surface. Suitable for mass production needs, rotary die-cutting machines are typically equipped with adjustable blade holders and tension control systems to adapt to different material widths and thicknesses. They also support multiple cutting modes, such as full cut, half cut, or scribing, for creating tear-off sections, labels, or functional slitting products. In actual production, rotary die-cutting machines are often used in conjunction with auxiliary materials (such as base film or release film) to complete the cutting of complex patterns through precise blade positioning and material traction. Furthermore, the waste collection system of the rotary die-cutting machine can simultaneously collect the waste material after cutting, ensuring the continuity and cleanliness of the production line. With its high efficiency and automation, this technology has become an indispensable process foundation in the die-cutting industry and is widely used in packaging, electronics, and medical fields.

[0003] Currently, traditional circular blade cutting mostly involves direct blade cutting, which makes it difficult to trace and refine the cutting path simultaneously, thus hindering the provision of a clear visual reference for the subsequent circular blade cutting path. This can easily lead to edge line breaches and inaccurate cutting due to operator visual estimation errors. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a simple hand-tearable knife holder fixture for a circular knife machine.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a simple hand-tearable knife holder fixture for a circular knife machine, comprising a guide arm and materials. The guide arm has a guide rod on its side, a fixing clamp on the surface of the guide rod, a mounting seat on the surface of the fixing clamp, a knife groove on the side of the mounting seat, a blade on the surface of the knife groove, a placement groove on the surface of the mounting seat, an edging nozzle on the surface of the placement groove, and a first fixing screw and a second fixing screw on the side of the mounting seat.

[0006] Preferably, the surface of the fixing clamp is provided with a tightening screw, and the shape and position of the fixing clamp are adapted to the guide rod.

[0007] Preferably, the surface of the mounting base is provided with mounting screws, and the mounting base is fixedly connected to the surface of the fixing clamp by the mounting screws.

[0008] Preferably, the end of the outlining nozzle is provided with a connecting pipe, and the outlining nozzle is disposed on one side of the blade.

[0009] Preferably, the position of the first fixing screw corresponds to the blade, and the blade is connected to the mounting base via the first fixing screw.

[0010] Preferably, the position of the second fixing screw corresponds to the outlining nozzle, and the outlining nozzle is connected to the mounting base via the second fixing screw.

[0011] Preferably, the fixing clamp and the mounting base are arranged axially symmetrically on the surface of the guide rod, and the material is disposed on the bottom surface of the blade and the tracing nozzle.

[0012] Beneficial effects This invention employs a blade, an outlining nozzle, a first fixing screw, and a second fixing screw. By placing the outlining nozzle on the front side of the blade, it achieves precise marking of the cutting path and simultaneous edge trimming. The outlining nozzle sprays marking lines onto the material surface to provide visual guidance, and then the blade trims and cuts along the marked path, thereby reducing deviations caused by operator visual error. Furthermore, the marking lines facilitate checking for any deviations during subsequent circular blade cutting, ensuring cutting quality. Simultaneously, the first and second fixing screws respectively fix the blade and the outlining nozzle to the mounting base, ensuring stable positioning of the components and facilitating quick adjustment and replacement. This simplified operation mode, which completes outlining and cutting within a single process, further improves production efficiency and ensures the overall precision and stability of die-cutting manufacturing.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-3 A simple hand-tearable die holder fixture for a circular die-cutting machine includes a guide arm 1 and a material 2. A guide rod 3 is provided on the side of the guide arm 1, and a fixing clamp 4 is provided on the surface of the guide rod 3. The fixing clamp 4 and the mounting base 5 are axially symmetrically arranged on the surface of the guide rod 3. The material 2 is provided on the bottom surface of the blade 8 and the tracing nozzle 10. The guide arm 1, as the main support frame of the fixture, is located on both sides of the device and fixed to the circular die-cutting machine. The guide arm 1 is made of high-strength material 2, providing stable mechanical support for the entire fixture and ensuring the structural stability of the device during high-speed cutting and tracing operations. The material 2, as the processing object, is the target object for die-cutting manufacturing, and its surface receives the marking lines from the tracing nozzle 10 and the cutting force from the blade 8. In the cutting operation, the guide rod 3 connects the transverse rods of the two guide rod arms 1, serving as a sliding track for the fixed clamp 4 and the mounting base 5. The guide rod 3 provides a linear movement path for the fixed clamp 4 and the mounting base 5, supporting the flexible positioning of the blade 8 and the tracing nozzle 10. Its surface is polished to reduce frictional resistance and ensure smooth clamp sliding, thus adapting to the needs of different material widths and cutting positions. The surface of the fixed clamp 4 is equipped with tightening screws 6. The shape and position of the fixed clamp 4 are adapted to the guide rod 3. The surface of the fixed clamp 4 is equipped with a mounting base 5, and the surface of the mounting base 5 is equipped with mounting screws 13. The mounting base 5 is fixedly connected to the surface of the fixed clamp 4 by the mounting screws 13. The mounting base 5 is connected to the guide rod 3 by the tightening screw 6, which can slide and lock along the guide rod 3 to ensure the stability and positional accuracy of the mounting base 5. Its axisymmetric design is adapted to the guide rod 3 to ensure balanced force, prevent displacement during operation, and improve the mechanical reliability of the overall device. The mounting base 5 provides a tool slot 7 and a placement slot 9 for fixing the blade 8 and the outlining nozzle 10. Its surface is firmly connected to the fixing clamp 4 by the mounting screw 13 to ensure no loosening during operation. The side design of the mounting base 5 supports the installation of the first fixing screw 11 and the second fixing screw 12, which facilitates the quick adjustment and replacement of the blade 8 and the outlining nozzle 10. The tightening screw 6 controls the loosening and locking state of the fixing clamp 4 through the thread friction. When the tightening screw 6 is loosened, the fixing clamp 4 can slide along the guide rod 3 to adjust its position. After the tightening screw 6 is tightened, the fixing clamp 4 is firmly locked to prevent displacement during high-speed operation and ensure the positioning accuracy of the blade 8 and the outlining nozzle 10.

[0018] The mounting base 5 has a tool groove 7 on its side, and a blade 8 is provided on the surface of the tool groove 7. The mounting base 5 also has a placement groove 9 on its surface, and a tracing nozzle 10 is provided on the surface of the placement groove 9. A connecting tube 14 is provided at the end of the tracing nozzle 10, which is positioned on one side of the blade 8. The mounting base 5 has a first fixing screw 11 and a second fixing screw 12 on its side. The first fixing screw 11 corresponds to the blade 8, and the blade 8 is connected to the mounting base 5 via the first fixing screw 11. The second fixing screw 12 corresponds to the tracing nozzle 10, and the tracing nozzle 10 is connected to the mounting base 5 via the second fixing screw 12. The size and shape of the tool groove 7 precisely match the blade 8, ensuring accurate and stable alignment during installation. The clamping force of the first fixing screw 11 secures the blade 8 in the tool groove 7, preventing vibration or displacement during cutting, thus ensuring the accuracy of hand-tearing or trimming cuts. The blade 8 is made of high-hardness stainless steel 2 and makes precise cuts along the marking lines drawn by the tracing nozzle 10, completing hand-tearing, trimming, or slitting operations. The placement slot 9 provides a precise installation position for the tracing nozzle 10, ensuring an appropriate distance between the tracing nozzle 10 and the surface of the material 2. The slot's design matches the shape of the tracing nozzle 10, and it is fixed by the second fixing screw 12 to ensure the stability of the nozzle during operation and prevent the marking line from shifting. The tracing nozzle 10 is positioned in front of the blade 8 and supplies ink through the connecting tube 14 to draw marking lines on the surface of the material 2. The tracing nozzle 10 uses a precision nozzle to spray fast-drying industrial marking ink before cutting, forming a clear cutting path guide line, making it easy for the operator to confirm the position and reducing visual errors. Its position is fixed by the second fixing screw 12, supporting quick adjustment and replacement. The connecting tube 14 connects to the tracing nozzle 10. The ink supply system delivers ink to the tracing nozzle 10. The connecting pipe 14 smoothly delivers ink from the storage tank to the tracing nozzle 10, ensuring a continuous and leak-free spraying process. The first fixing screw 11 securely fixes the blade 8 in the blade groove 7 through threaded clamping force, preventing the blade 8 from loosening or shifting during cutting. Its design allows for quick loosening or tightening, supporting the replacement and fine-tuning of the blade 8 to ensure cutting accuracy. The second fixing screw 12 fixes the tracing nozzle 10 in the placement groove 9 through threaded clamping force, ensuring the stability of the tracing nozzle 10 when spraying marking lines. Its quick-tightening design facilitates the installation, disassembly, and position adjustment of the tracing nozzle 10, adapting to different materials 2 and cutting requirements.

[0019] The operation is as follows: First, fix the guide arm 1 onto the circular knife machine, ensuring the guide rod 3 is horizontal and aligned with the machine interface. Then, loosen the tightening screw 6 on the fixing clamp 4, slide the fixing clamp 4 and the mounting base 5 along the guide rod 3 to the desired position, and tighten the tightening screw 6 to lock them in place. Next, install the blade 8 into the tool groove 7 of the mounting base 5 and secure it with the first fixing screw 11, ensuring the blade 8 is firmly aligned. At the same time, install the outlining nozzle 10 into the placement groove 9 of the mounting base 5 and secure it with the second fixing screw 12. Connect the ink supply system to the connecting pipe 14, adjust the distance between the printhead and the surface of material 2 to 1-2mm, then calibrate the device, run a small amount of material 2, check whether the marking line drawn by the tracing printhead 10 is consistent with the cutting path of the blade 8, and fine-tune the mounting base 5 or the printhead position if necessary. Finally, start the circular die cutter, the tracing printhead 10 sprays quick-drying marking lines on the surface of material 2 to provide cutting guidance, and the blade 8 then performs hand-tear or trimming cuts along the marking lines, completing the single process of tracing and trimming at the same time, and achieving efficient and accurate die-cutting processing. Specific Implementation Example 2: Reference Figure 4 A simple hand-tearable die holder fixture for a circular die-cutting machine, based on the basic structure in Specific Embodiment 1, further discloses the following: a fixing clamp 4 and a dividing blade can be additionally set in the middle of the guide rod 3 to achieve a convenient separation function. When collecting waste material, uneven tension on both sides is prone to occur, causing the product to fall off during the scraping process. With the additionally configured fixing clamp 4 and dividing blade, the hand-tearable die holder can evenly divide the waste material into two parts and independently rewind them, thereby effectively balancing the tension on both sides, ensuring the stability of the material 2 processing process and the reliability of product quality, and further improving the overall efficiency and economy of die-cutting manufacturing.

[0021] In summary: 1. Using a blade 8, an tracing nozzle 10, a first fixing screw 11, and a second fixing screw 12, the tracing nozzle 10 is positioned in front of the blade 8, achieving precise marking of the cutting path and simultaneous trimming. The tracing nozzle 10 sprays marking lines onto the surface of the material 2 to provide visual guidance. Subsequently, the blade 8 trims and cuts along the marked path, thereby reducing deviations caused by operator visual error. The marking lines also facilitate checking for lines during subsequent circular knife cutting, ensuring cutting quality. At the same time, the first fixing screw 11 and the second fixing screw 12 respectively fix the blade 8 and the tracing nozzle 10 to the mounting base 5, ensuring stable positioning of the components and facilitating quick adjustment and replacement. This achieves a simple operation mode that completes tracing and cutting in a single process, further improving production efficiency and ensuring the overall precision and stability of die-cutting manufacturing.
