Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery and automated cutting equipment, and in particular to a modular cutter head for adaptive multi-material cutting. Background Technology

[0002] With the rapid development of the textile industry, the demand for labels in apparel, home textiles, and daily consumer goods is constantly increasing, especially the proportion of polyester and cotton blended labels. Due to the significant differences in hardness, toughness, and fiber structure among different materials, the requirements for blade performance during label cutting are more complex. If the cutting equipment cannot flexibly adapt to the characteristics of multiple materials, it will not only reduce cutting efficiency but also affect the smoothness of the cut and the quality of the finished product. Therefore, developing a modular cutter head that adapts to multi-material cutting is of great significance for improving production efficiency and processing quality.

[0003] Existing label cutting equipment primarily uses a fixed cutter head structure, with a motor driving the cutter to move along a set trajectory to cut the label. The cutter head design is typically geared towards a single material, relying on blade sharpness and cutting angle to ensure cutting quality. In actual production, traditional cutter heads are sufficient for processing pure cotton, polyester, or other materials. However, with the increasing prevalence of mixed-material labels, single-material-compatible cutter heads often require blade replacement to maintain cutting quality when dealing with materials of different hardness and fiber density, thus increasing the complexity of the process.

[0004] However, existing cutting equipment generally uses single-material compatible cutter heads, lacking the ability to adapt to multiple materials. When the production line needs to switch from cotton to polyester or blended materials, it often has to stop the machine to replace the cutter, resulting in a significant drop in production efficiency. At the same time, frequent cutter head replacements also increase equipment wear and tear and the labor intensity of operators, further affecting the overall production rhythm and processing costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular cutter head for adaptive multi-material cutting, which aims to improve the problem of low replacement efficiency caused by the use of single-material adaptable cutter heads in traditional cutting equipment, and the need to frequently stop the machine to replace the cutter when switching between materials with different hardness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular cutter head for adaptive multi-material cutting, including a connecting frame, a protective plate slidably connected to the inner wall of the connecting frame, a blade fixedly connected to the inner wall of the protective plate, and a quick-release assembly provided on the inner wall of the connecting frame; The quick-release assembly includes a quick-release rod, the outer wall of which is slidably connected to the inner wall of a connecting frame. A second fixing block is fixedly connected to the inner wall of the connecting frame. A threaded block is fixedly connected to the inner wall of the quick-release rod. A threaded rod is threadedly connected to the inner wall of the threaded block. A tapered block is rotatably connected to one end of the threaded rod. A locking sleeve is fixedly connected to the inner wall of the quick-release rod. The outer wall of the tapered block is slidably connected to the inner wall of the locking sleeve. A locking block is fixedly connected to the outer wall of the locking sleeve. A locking groove is provided inside the second fixing block. The outer wall of the locking block is slidably connected to the locking groove inside the second fixing block.

[0007] The above technical solution enables the rapid disassembly and secure locking of the blade within the connecting frame: the threaded rod drives the tapered block to expand the locking sleeve, thereby allowing the locking block to enter the slot of the second fixing block to complete the engagement. This allows the blade to be efficiently replaced and securely fixed between different material cutting requirements, avoiding the problems of cumbersome blade replacement and long downtime in traditional blade replacement, and improving the adaptability and work efficiency of the device.

[0008] Preferably, a second connecting block is fixedly connected to the outer wall of the connecting frame, and a connecting plate is rotatably connected to the outer wall of the second connecting block.

[0009] The above technical solution enables the connecting plate to be flexibly rotated and installed on the connecting frame, allowing it to serve as a support structure for the installation and adjustment of protective plates or related components, facilitating position adjustment and fixation, thereby enhancing the overall adjustability and adaptability of the cutter head.

[0010] Preferably, the outer wall of the connecting plate is fixedly connected with a pin, and the inner wall of the protective plate is provided with multiple fixing holes.

[0011] The above technical solution enables the pin to work in conjunction with multiple fixing holes on the protective plate, allowing the protective plate to be quickly positioned and reliably fixed in different locations, thereby flexibly adjusting the protection range according to the blade specifications, cutting depth, and material thickness.

[0012] Preferably, the outer wall of the pin is slidably connected to a fixing hole opened inside the protective plate, and both ends of the connecting frame are fixedly connected to sliding sleeves.

[0013] The above technical solution achieves sliding positioning of the pin in the fixing hole and adjustable fixing of the protective plate. At the same time, the sliding sleeves at both ends of the connecting frame can be used with connecting rods and other mechanisms to ensure the smooth movement and balanced force of the cutter head during the cutting process.

[0014] Preferably, a fixing block is provided below the sliding sleeve, and a connecting rod is fixedly connected to the upper surface of the fixing block.

[0015] The above technical solution achieves a stable installation and support for a pair of connecting rods on the fixed block, enabling the connecting rods to stably drive the sliding sleeve to extend and retract, thereby driving the cutter head or related components to rise or fall or adjust their position. This ensures the smoothness and controllability of the cutter movement during the cutting process, and improves the operational flexibility and cutting accuracy of the device.

[0016] Preferably, a sliding sleeve is slidably connected to the outer wall of the connecting rod, and a limit nut is fixedly connected to the outer wall of the connecting rod.

[0017] The above technical solution enables the sliding sleeve to slide on the connecting rod, allowing the cutter head to move smoothly up and down. At the same time, the limit nut restricts the stroke of the connecting rod, reducing excessive extension or retraction of the cutter.

[0018] Preferably, a connecting block is fixedly connected to the outer wall of the connecting frame, a limiting rod is slidably connected to the inner wall of the connecting block, and a pressing block is fixedly connected to one end of the limiting rod.

[0019] The above technical solution enables the sliding installation of the limiting rod within the connecting block 1, and limits or presses the relevant components through the pressing block at its end, thus playing an auxiliary role in fixing and positioning during the operation or replacement of the cutter head.

[0020] Preferably, a spring is sleeved on the outer wall of the limiting rod, one end of the spring is fixedly connected to the lower surface of the connecting block, and the other end of the spring is fixedly connected to the upper surface of the extrusion block.

[0021] The above technical solution achieves the elastic reset effect of the spring on the limiting rod and the extrusion block, so that the extrusion block can automatically return to its initial position after the external force is removed, thereby ensuring that the limiting structure is always in an effective working state. This not only facilitates the quick fixing and release of the tool, but also improves the stability of the structure and the convenience of operation.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by setting a quick-release component in the connecting frame, the blade can be quickly installed and removed on the connecting frame. When it is necessary to replace the blade with one suitable for a different material, simply rotate the threaded rod to drive the conical block to push the locking sleeve to expand or contract, thereby completing the engagement or disengagement of the locking block and the slot. This structure is not only easy to operate and can greatly shorten the blade replacement time, reduce equipment downtime, improve the adaptability and work efficiency of multi-material cutting, but also avoids the problems of installation errors and reduced cutting accuracy caused by frequent disassembly and assembly of traditional blades.

[0023] 2. In this utility model, the protective plate, the pin and the fixing hole are combined to achieve adjustable positioning of the blade protection range. The protective plate can be flexibly adjusted according to different blade specifications, cutting depth and material thickness. While ensuring the blade movement space and cutting efficiency, it effectively prevents the operator from direct contact with the high-speed moving blade and reduces safety risks.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 - Figure 6 The present invention provides an embodiment of a modular cutter head for adaptive multi-material cutting, including a connecting frame 5. The connecting frame 5 is used to install and support quick-release components and is the basic structure for realizing the installation, removal and protection of the cutter. A protective plate 16 is slidably connected to the inner wall of the connecting frame 5. A blade 17 is fixedly connected to the inner wall of the protective plate 16. The blade 17 is used to cut different materials of fabric and is the working core of the entire device. A quick-release component is provided on the inner wall of the connecting frame 5. The quick-release assembly includes a quick-release rod 10, which is installed on the inner wall of the connecting frame 5 and serves as the core load-bearing component of the quick-release assembly. It also cooperates with the threaded rod 18 to enable the quick installation and removal of the blade 17. The outer wall of the quick-release rod 10 is slidably connected to the inner wall of the connecting frame 5. A fixing block 23 is fixedly connected to the inner wall of the connecting frame 5. A threaded block 23 is fixedly connected to the inner wall of the quick-release rod 10. The threaded rod 18 is threadedly connected to the inner wall of the threaded block 23. When the threaded rod 18 rotates, it can drive the conical block 21 to move, thereby squeezing or releasing the locking sleeve 19, thus locking or unlocking the blade 17. One end of the threaded rod 18 is rotatably connected to a tapered block 21. A locking sleeve 19 is fixedly connected to the inner wall of the quick-release rod 10. The outer wall of the tapered block 21 is slidably connected to the inner wall of the locking sleeve 19. The locking sleeve 19 is used to cooperate with the tapered block 21. By radially expanding or contracting, it pushes the locking block 20 to engage, thereby achieving a quick locking function. The locking block 20 is fixedly connected to the outer wall of the locking sleeve 19. A slot 22 is opened inside the fixed block 23. The outer wall of the locking block 20 is slidably connected to the slot 22 opened inside the fixed block 23. The slot 22 is used to accommodate the locking block 20, thereby limiting and locking the quick-release assembly and ensuring reliable tool connection.

[0029] Specifically, by rotating the threaded rod 18, the conical block 21 can be driven to move within the locking sleeve 19, generating pressure on the locking sleeve 19 and causing it to expand outward. This drives the locking block 20 into the slot 22 to achieve reliable engagement, thus locking the blade 17 and the connecting frame 5. Reverse operation can achieve quick unlocking, completing the disassembly and replacement of the blade 17. This structure enables the rapid installation and disassembly of the blade 17, ensuring the flexible adaptation of the blade to different material cutting conditions, improving overall operating efficiency, reducing downtime caused by frequent blade 17 replacements, and improving the continuity and reliability of the cutting equipment.

[0030] Reference Figure 1 - Figure 6A connecting block 11 is fixedly connected to the outer wall of the connecting frame 5. A connecting plate 12 is rotatably connected to the outer wall of the connecting block 11. The connecting plate 12 is used to fix or adjust the position of the protective plate 16, so as to facilitate the adjustment of the protection range. A pin 14 is fixedly connected to the outer wall of the connecting plate 12. Multiple fixing holes 15 are opened on the inner wall of the protective plate 16. The fixing holes 15 are for the pin 14 to be inserted, so as to realize the adjustable fixation of the protective plate 16 and make the protection range flexibly change as needed. The pin 14 is slidably connected to the outer wall of the fixing hole 15 opened inside the protective plate 16. Sliding sleeves 3 are fixedly connected to both ends of the connecting frame 5. The sliding sleeves 3 are connected to the connecting rod 2, which plays a role in transmitting displacement and providing support.

[0031] Specifically, the protective plate 16 is flexibly adjustable through the connecting block 11 and the connecting plate 12. The connecting plate 12 can support the protective plate 16 and adjust its position, so that the protection range can be freely changed according to the cutting requirements. The pin 14 works in conjunction with the multiple fixing holes 15 opened on the protective plate 16 to achieve quick positioning and stable fixing of the protective plate 16. While ensuring the safety of the operator, it does not affect the movement space of the cutting tool. The adjustable design of the protective plate 16 can adapt to different blade 17 specifications and cutting depths, effectively blocking the safety risks brought by the high-speed moving blade 17.

[0032] Reference Figure 1 - Figure 6 A fixing block 1 is provided below the sliding sleeve 3. A connecting rod 2 is fixedly connected to the upper surface of the fixing block 1. The sliding sleeve 3 is slidably connected to the outer wall of the connecting rod 2. A limit nut 4 is fixedly connected to the outer wall of the connecting rod 2. The limit nut 4 is used to limit the maximum stroke of the sliding sleeve 3 to prevent the connecting rod 2 from excessively extending or retracting and causing structural damage, and to ensure safe and reliable operation. A connecting block 6 is fixedly connected to the outer wall of the connecting frame 5. A limit rod 7 is slidably connected to the inner wall of the connecting block 6. A pressing block 9 is fixedly connected to one end of the limit rod 7. The pressing block 9 is connected to the limit rod 7 and achieves the clamping function through pressing. A spring 8 is sleeved on the outer wall of the limit rod 7. One end of the spring 8 is fixedly connected to the lower surface of the connecting block 6, and the other end of the spring 8 is fixedly connected to the upper surface of the pressing block 9. The spring 8 provides elastic restoring force for the limit rod 7, so that the pressing block 9 can automatically return to its position after the external force is removed, and can press different fabrics.

[0033] Specifically, the fixed block 1 provides stable support for the connecting rod 2, allowing the sliding sleeve 3 to slide on the connecting rod 2, thereby achieving automatic adjustment of the blade 17. This reduces manual operation and improves the accuracy and stability of adjustment. The connecting rod 2, in conjunction with the limiting nut 4, can limit the maximum stroke of the sliding sleeve 3, preventing excessive extension and retraction of the connecting rod 2 that could cause structural damage and ensuring the safe and reliable operation of the device. The limiting rod 7, in conjunction with the squeezing block 9 and the spring 8, can apply stable clamping force to different fabrics. The spring 8 provides elastic restoring force, allowing the squeezing block 9 to automatically return to its original position after the external force is removed, achieving a continuous and uniform clamping effect. This design not only ensures the stability of the blade 17 during the cutting process but also adapts to the cutting needs of fabrics of different thicknesses or materials, improving the reliability, continuity, and overall work efficiency of the cutting operation.

[0034] Working principle: When a modular cutter head with adaptive multi-material cutting is needed, and different blades 17 need to be replaced to adapt to different fabric materials, the inner wall of the connecting frame 5 has a quick-release lever 10. A threaded block 23 is fixed to the inner wall of the quick-release lever 10. The inner wall of the threaded block 23 is threadedly connected to the threaded rod 18. One end of the threaded rod 18 has a tapered block 21 that rotates. The outer wall of the tapered block 21 slides against the inner wall of the locking sleeve 19. A locking block 20 is fixed to the outer wall of the locking sleeve 19. The locking block 20 slides within the slot 22 inside the fixing block 13. When it is necessary to replace the blade... When the blade 17 is cut, the rotating threaded rod 18 causes the conical block 21 to move within the locking sleeve 19, thereby squeezing the locking sleeve 19 to expand outwards, thus pushing the locking block 20 into the slot 22 for engagement, thereby locking or unlocking the blade 17 and the connecting frame 5. Through this quick-release structure, the blade head can be quickly switched between different hardness or different materials for cutting needs, reducing the inefficiency caused by the need for frequent machine stops to change blade heads of a single material in traditional devices, thereby improving the adaptability and work efficiency of the equipment in multi-material cutting operations; Furthermore, during the cutting process, the protective plate 16 is used to protect the blade 17, reducing the safety risks caused by the high-speed movement of the blade. The inner wall of the protective plate 16 has multiple fixing holes 15, and the outer wall of the connecting plate 12 is fixed with a pin 14. The pin 14 can be inserted into the fixing holes 15, thereby fixing and adjusting the position of the protective plate 16. When it is necessary to adjust the protection range, the pin 14 can be pulled out from the fixing hole 15, the protective plate 16 can be moved to a suitable position, and then the pin 14 can be reinserted into the fixing hole 15 to adjust the height or position of the protective plate 16. This structure can flexibly adjust the protection range according to different blade 17 specifications, cutting depths, and the thickness of the material to be cut, so that the protective plate 16 can effectively block the operator from direct contact with the blade, reducing safety risks, without affecting the blade's movement space and cutting efficiency. Through the adjustable design of the protective plate 16, the continuity and accuracy of the cutting operation are ensured while ensuring operational safety.
