Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and more specifically, to a quick-release fabric cutting device. Background Technology

[0002] In industries such as textiles, garment processing, and fabric deep processing, fabric cutting is a critical step in the production process, directly affecting the forming accuracy and production efficiency of subsequent products. With the increasing demand for mass production, companies need to achieve continuous and efficient fabric cutting, while also frequently replacing cutting components or performing regular maintenance on the cutting mechanism according to different product specifications to ensure the stability of cutting quality.

[0003] Most fabric cutting devices on the market are equipped with a conveying mechanism and a cutting component. The conveying mechanism is driven by a drive component to transport the fabric, and the cutting component completes the cutting operation of the fabric, which can basically meet the basic cutting needs.

[0004] However, existing fabric cutting devices still have certain problems in practical applications: On the one hand, the installation and disassembly of the cutting components are cumbersome, usually requiring the use of special tools to gradually disassemble the fixed structure, and the replacement or maintenance process is time-consuming, resulting in increased equipment downtime and seriously affecting production continuity; on the other hand, the positioning reliability of the cutting components is poor. After long-term high-frequency operation, the positioning structure is prone to loosening or shifting, causing the relative position of the cutting components and the conveying mechanism to deviate, which in turn leads to a decrease in fabric cutting accuracy and problems such as rough edges and dimensional deviations. At the same time, the adaptability of traditional positioning structures is poor, making it difficult to stably cope with the cutting needs under different working conditions, affecting the overall operational stability of the equipment. Therefore, we urgently need a quick-release fabric cutting device to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a quick-release fabric cutting device.

[0006] According to a first aspect of the present invention, a quick-release fabric cutting device is provided, comprising a frame and a conveyor roller mounted on the frame, the conveyor roller being connected to a drive motor on the frame, and further comprising: symmetrically opened placement openings on the frame, the frame being provided with mounting rods for loading cutting blades, both ends of the mounting rods being provided with snap-fit ​​grooves, and when the mounting rods are located in the corresponding placement openings, they are locked by limiting members; both ends of the mounting rods are fixedly connected with insertion blocks, and the frame is symmetrically provided with insertion sleeves adapted to the insertion blocks, the insertion sleeves being slidably disposed on the frame, and when the insertion sleeves are engaged with the insertion blocks, a positioning area is formed.

An arc-shaped plate adapted to the snap-fit ​​groove is hinged on the arc-shaped protrusion. When the arc-shaped protrusion abuts against the inner wall of the snap-fit ​​groove, the arc-shaped plate rotates and abuts against the inner wall of the snap-fit ​​groove to form a wrapping area.

[0008] Optionally, a first magnetic groove is provided on the arc-shaped protrusion, and a magnetic buckle is installed on the arc-shaped plate corresponding to the first magnetic groove. When in the wrapping area, the magnetic buckle is located in the first magnetic groove and magnetically attracted to it.

[0009] Optionally, electric rails are symmetrically installed on the frame, and the output ends of the two sets of electric rails are fixedly connected to connecting frames. The plug-in sleeve is fixedly connected to the connecting frame. When the electric rails are working, the plug-in sleeve contacts or disengages from the plug-in block.

[0010] Optionally, a rotating rod is rotatably connected to the insert sleeve, and a tapered end is fixedly connected to the rotating rod. A sliding groove is equidistantly formed on the tapered end. An annular ring is fixedly installed on the insert sleeve, and a second magnetic groove is equidistantly formed on the annular ring. Double-sided magnetic rods are equidistantly installed on the rotating rod, and the double-sided magnetic rods are located within the corresponding second magnetic grooves. When the rotating rod rotates, the double-sided magnetic rods magnetically attract one side of the second magnetic groove, forming a first working area. When the double-sided magnetic rods magnetically attract the other side of the second magnetic groove, a second working area is formed.

[0011] Optionally, the plug-in block is provided with equidistant inclined rods for limiting the position, and the plug-in sleeve is provided with a matching insertion port at the corresponding position of the inclined rod. The plug-in block is provided with a circular through hole connected to its inner hole between the two sets of inclined rods. A limiting rod is movably connected to the circular through hole by a spring. The plug-in sleeve is provided with a limiting insertion hole adapted to the limiting rod. When the plug-in sleeve is inserted into the plug-in block, one end of the limiting rod is in the sliding groove, and the other end is inserted into the limiting insertion hole to form a positioning area.

[0012] Optionally, the tapered end is provided with a positioning notch that communicates with the slide groove. When in the positioning area, the rotating rod is in the first working area.

It can complete the initial positioning and secondary docking of the installation rod without special tools, which helps to shorten the downtime of cutting blade replacement and equipment maintenance, reduce the difficulty of operation for operators, and can improve production continuity and operation convenience to a certain extent.

[0015] 2.

Combined with the guiding cooperation of the guide rod and the guide hole, and the vibration-resistant positioning design of the magnetic suction structure, it can constrain the displacement deviation of the mounting rod from multiple dimensions. This helps to improve the situation where the cutting components are prone to loosening and displacement during equipment operation, improves cutting accuracy and operational stability, and at the same time helps to reduce the mechanical wear of the positioning structure and extend the overall service life of the device.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] like Figure 1-8As shown, a quick-release fabric cutting device includes a frame 1 and a conveyor roller 2 mounted on the frame 1. The conveyor roller 2 is connected to a drive motor on the frame 1.

[0032] Here, the frame 1 and the rotatable conveyor roller 2 are direct references to the prior art, and will not be elaborated further.

[0033] It also includes placement openings 3 symmetrically opened on the frame 1. The frame 1 is provided with mounting rods 4 for loading cutting blades. Both ends of the mounting rods 4 are provided with snap-fit ​​grooves 5. When the mounting rods 4 are located in the corresponding placement openings 3, they are locked by limiting members.

[0034] Here, the placement openings 3 are symmetrically arranged on the frame 1, providing uniform load-bearing support space for both ends of the mounting rod 4, preventing unilateral force on the mounting rod 4 and thus avoiding skewing. Simultaneously, they provide space for the assembly and locking of the limiting components, ensuring the initial neatness of the mounting rod 4 assembly. As a dedicated load-bearing component for the cutting blade, the mounting rod 4 can integrate multiple cutting blades, achieving modular design of the cutting components and facilitating overall disassembly and specification replacement. The snap-fit ​​grooves 5 are located at both ends of the mounting rod 4, enabling precise engagement with the limiting components and providing dedicated locking points for the initial locking of the mounting rod 4, preventing assembly interference between the limiting structure and the main body of the mounting rod 4.

[0035] Furthermore, the symmetrical placement port 3 and the two-end snap-fit ​​groove 5 are mutually compatible, eliminating the complex structure of traditional bolt-through locking. The initial alignment of the installation rod 4 can be completed without the need for special tools, simplifying the operation process in the early stage of assembly and reducing the difficulty of operation for operators.

[0036] Furthermore, the structural design optimizes the assembly foundation of the cutting blade bearing component. It achieves initial positioning through dedicated locking points, ensuring the positional accuracy of the mounting rod 4 and providing a stable benchmark for the subsequent multi-stage positioning and locking structure. This solves the problems of cumbersome disassembly and assembly of cutting components and unclear positioning benchmarks in traditional fabric cutting devices.

[0037] The limiting component includes an arc-shaped protrusion 8 fixedly installed on the inner wall of the placement opening 3. The arc-shaped protrusion 8 is adapted to the snap-fit ​​groove 5. An arc-shaped plate 9 adapted to the snap-fit ​​groove 5 is hinged on the arc-shaped protrusion 8. When the arc-shaped protrusion 8 abuts against the inner wall of the snap-fit ​​groove 5, the arc-shaped plate 9 rotates and abuts against the inner wall of the snap-fit ​​groove 5 to form a wrapping area.

[0038] Here, the contour of the arc-shaped protrusion 8 matches the snap-fit ​​groove 5. After the mounting rod 4 is inserted into the placement opening 3, it can quickly fit and abut against the inner wall of the snap-fit ​​groove 5, achieving initial snap-fit ​​and limiting of the mounting rod 4 and preventing radial wobbling of the mounting rod 4. The arc-shaped plate 9 is connected to the arc-shaped protrusion 8 by a hinge and can be freely flipped. After the arc-shaped protrusion 8 completes the initial abutment, flipping the arc-shaped plate 9 allows it to fit against the inner wall of the other side of the snap-fit ​​groove 5. The two work together to form a wrap-around limiting area surrounding the snap-fit ​​groove 5.

[0039] Furthermore, the hinged arc plate 9, combined with the fixed arc protrusion 8, forms an openable and closable wrapping and limiting structure. The opening and closing operation can be completed by hand without special tools, which greatly improves the efficiency of the initial locking and disassembly of the mounting rod 4 and reduces downtime during equipment maintenance and cutting blade replacement.

[0040] Furthermore, the wrap-around limiting structure can fit snugly against the inner wall of the snap-fit ​​groove 5 in all directions, increasing the contact area between the limiting structure and the mounting rod 4, improving the stability of the initial limiting, preventing the mounting rod 4 from moving radially during equipment operation, ensuring the initial stability of the cutting operation, and making up for the shortcomings of traditional limiting structures such as small contact area and easy loosening.

[0041] The arc-shaped protrusion 8 has a first magnetic groove 10, and the arc-shaped plate 9 has a magnetic buckle 11 installed at the first magnetic groove 10. When it is in the wrapping area, the magnetic buckle 11 is located in the first magnetic groove 10 and magnetically attracted to it.

[0042] Here, the first magnetic groove 10 and the magnetic buckle 11 are set one-to-one. After the arc plate 9 is flipped to form a wrapping area, the magnetic buckle 11 can be accurately embedded in the first magnetic groove 10. The arc plate 9 is automatically fixed by magnetic attraction without the need for additional mechanical locking components.

[0043] Furthermore, the magnetic fixing method eliminates the tedious steps of screwing in bolts and snapping in clips. Once the arc plate 9 is flipped into place, it can be automatically attracted and fixed, simplifying the locking operation. When disassembling, only the magnetic force needs to be overcome to flip open the arc plate 9, further improving the efficiency of disassembly and assembly.

[0044] Furthermore, the magnetic attraction structure provides a continuous and stable locking force, preventing the arc plate 9 from accidentally flipping due to equipment vibration and ensuring the reliability of the initial limiting structure. At the same time, the magnetic attraction structure has no risk of mechanical jamming and is not prone to wear and jamming after long-term use, effectively extending the service life of the limiting structure.

[0045] Both ends of the mounting rod 4 are fixedly connected to the plug-in block 6, and the frame 1 is symmetrically provided with plug-in sleeves 7 that are compatible with the plug-in block 6.

[0046] Here, the plug-in block 6 is fixed to both ends of the mounting rod 4, forming a matching plug-in structure with the symmetrically arranged plug-in sleeves 7. The symmetrical arrangement can ensure that the forces on both ends of the mounting rod 4 are balanced, avoiding the displacement of the cutting parts caused by unilateral positioning failure.

[0047] Furthermore, the plug-in block 6 and the plug-in sleeve 7 adopt a precise fit design, which can achieve seamless docking and cooperation, build a two-level positioning structure for the installation rod 4, and form a multi-level positioning system with the front-end snap-fit ​​locking structure, thereby improving the overall positioning reliability layer by layer.

[0048] Furthermore, the positioning structure is divided into two parts: a preliminary snap-fit ​​and a secondary insertion, which achieves the positioning and locking of the mounting rod 4 in stages. This not only ensures that the assembly process is controllable step by step, but also disperses the force through multi-level positioning, reducing the load on a single positioning structure and improving the stability and durability of the overall structure.

[0049] The insertion sleeve 7 is slidably mounted on the frame 1. When the insertion sleeve 7 is engaged with the insertion block 6, a positioning area is formed. Electric rails 12 are symmetrically mounted on the frame 1. The output ends of the two sets of electric rails 12 are fixedly connected to the connecting frame 13. The insertion sleeve 7 is fixedly connected to the connecting frame 13. When the electric rails 12 are working, the insertion sleeve 7 contacts or disengages from the insertion block 6.

[0050] Here, the insert sleeve 7 is slidably mounted on the frame 1 and reciprocates linearly via electric drive. The connecting frame 13 connects the output ends of the two sets of electric rails 12, which can synchronously drive the displacement of the insert sleeves 7 on both sides, ensuring the synchronicity of the docking of the insert sleeves 7 with the insert block 6. The electric rails 12 provide stable power for the movement of the insert sleeves 7 and can precisely control the movement stroke of the insert sleeves 7.

[0051] Furthermore, electric drive is used to replace the traditional manual push and pull, so that the docking and separation of the plug sleeve 7 and the plug block 6 can be completed without the need for manual external force, reducing the intensity of manual operation; at the same time, the displacement accuracy of the electric track 12 is controllable, which can ensure that the plug sleeve 7 and the plug block 6 are accurately docked, avoiding docking deviations caused by manual operation.

[0052] Furthermore, the electrically driven sliding structure enables automated control of secondary positioning. Combined with the manual rapid initial positioning structure, it forms an operation mode of "manual rapid initial positioning + electric precise secondary positioning," which not only improves disassembly and assembly efficiency but also ensures positioning accuracy, effectively solving the problems of cumbersome positioning operation and difficulty in controlling accuracy in traditional fabric cutting devices.

[0053] A rotating rod 14 is rotatably connected to the insert sleeve 7. A tapered end 15 is fixedly connected to the rotating rod 14. A sliding groove 16 is equidistantly formed on the tapered end 15. An annular ring 17 is fixedly installed on the insert sleeve 7. A second magnetic suction groove 18 is equidistantly formed on the annular ring 17. A double-sided magnetic suction rod 19 is equidistantly formed on the rotating rod 14. The double-sided magnetic suction rod 19 is located in the corresponding second magnetic suction groove 18. When the rotating rod 14 rotates, the double-sided magnetic suction rod 19 magnetically attracts one side of the second magnetic suction groove 18 to form a first working area. When the double-sided magnetic suction rod 19 magnetically attracts the other side of the second magnetic suction groove 18, a second working area is formed.

[0054] Here, the rotating rod 14 is rotatably connected to the insertion sleeve 7, which can drive the conical end 15 to rotate synchronously. The conical structure of the conical end 15 facilitates insertion into the insertion block 6, achieving guided docking. The sliding groove 16 is equidistantly formed on the conical end 15 in an annular shape, providing suitable movement space for subsequent limiting components. The annular ring 17, the second magnetic suction groove 18, and the double-sided magnetic suction rod 19 form a magnetic suction-type workstation switching structure. The double-sided magnetic suction rod 19 can achieve double-sided magnetic attraction within the second magnetic suction groove 18, thereby forming two stable independent workstations.

[0055] Furthermore, the first and second working areas are independently fixed by magnetic attraction, and the workstation can be switched by rotating the rotating rod 14. The switching operation is simple and convenient, without complicated locking and unlocking steps, and can quickly realize the state transformation of the limiting components.

[0056] Furthermore, the slide 16, the second magnetic suction groove 18, and the double-sided magnetic suction rod 19 are all arranged in a ring with equal spacing to ensure that the tapered end 15 is subjected to uniform force in the circumference and that the workstation switching process is smooth and without jamming. At the same time, the magnetic workstation fixing can avoid the workstation shift caused by equipment vibration, ensure the stability of subsequent limit locking operations, and provide a reliable workstation guarantee for final accurate positioning.

[0057] The plug-in block 6 has equidistant inclined rods 20 for limiting the position. The plug-in sleeve 7 has a corresponding insertion port 21 on the inclined rod 20. The plug-in block 6 has a circular through hole 22 connected to its inner hole between the two sets of inclined rods 20. A limiting rod 24 is movably connected to the circular through hole 22 by a spring 23. The plug-in sleeve 7 has a limiting insertion hole 25 adapted to the limiting rod 24. When the plug-in sleeve 7 is inserted into the plug-in block 6, one end of the limiting rod 24 is in the sliding groove 16, and the other end is inserted into the limiting insertion hole 25 to form a positioning area.

[0058] Here, the tilting rod 20 and the insertion port 21 are adapted to each other to form a circumferential limiting structure, which can limit the relative circumferential rotation between the insertion sleeve 7 and the insertion block 6, prevent the two from rotating and offset, and ensure the angular accuracy of the cutting parts. The circular through hole 22 provides a sealed assembly space for the limiting rod 24 and the spring 23, and the spring 23 provides elastic reset power for the limiting rod 24, enabling the limiting rod 24 to move autonomously. One end of the limiting rod 24 is adapted to the slide groove 16, and the other end is engaged with the limiting insertion hole 25 to form a radial locking structure.

[0059] Furthermore, the tilting rod 20 and the socket 21 achieve circumferential limiting, and the limiting rod 24 and the limiting socket 25 achieve radial limiting. The two work together to limit the relative displacement of the plug sleeve 7 and the plug block 6 in both circumferential and radial dimensions, achieving all-round positioning with comprehensive and reliable positioning effect.

[0060] Furthermore, the flexible movable limiting rod 24, in conjunction with the sliding groove 16 of the tapered end 15, can automatically complete the telescopic locking during the insertion of the insert sleeve 7, eliminating the need for manual adjustment of the limiting components and achieving automated locking of the two-level positioning, further simplifying the assembly process; the multi-level limiting structure works together to effectively solve the problems of unstable positioning and easy displacement and loosening of the cutting components in traditional fabric cutting devices.

[0061] The tapered end 15 has a positioning notch 26 that communicates with the slide groove 16. When it is in the positioning area, the rotating rod 14 is in the first working area. When the rotating rod 14 is rotated to the second working area, the end of the limiting rod 24 is inserted into the positioning notch 26.

[0062] Here, the positioning notch 26 is connected to the slide groove 16 to provide the final fixing point for the limiting rod 24; when the rotating rod 14 is in the first working area, the limiting rod 24 can move freely in the slide groove 16 to ensure that the insertion sleeve 7 can be inserted normally and complete the initial engagement.

[0063] Furthermore, when the rotating rod 14 switches to the second working area, the positioning notch 26 rotates synchronously with the conical end 15 to the corresponding position of the limiting rod 24. Under the elastic force of the spring 23, the limiting rod 24 automatically embeds into the positioning notch 26, thereby locking the limiting rod 24 and preventing the limiting rod 24 from radially retracting.

[0064] Furthermore, the structure achieves two-stage locking of the limiting component. First, radial preliminary positioning is completed through the limiting rod 24 and the limiting insertion hole 25, and then fixation is achieved through the positioning notch 26. The double locking further improves the positioning reliability and prevents the limiting rod 24 from retracting during long-term operation of the equipment, thus preventing positioning failure and continuously ensuring the accuracy and stability of the cutting operation.

[0065] A guide rod 27 is fixedly connected to the inner hole of the plug block 6. A guide hole 28 adapted to the guide rod 27 is opened on the tapered end 15. When in the positioning area, the guide rod 27 abuts against the inner wall of the guide hole 28.

[0066] Here, the guide rod 27 is fixed in the inner hole of the plug-in block 6, and the guide hole 28 is opened at the tapered end 15. The two form a precise guiding and mating structure, which plays a role in guiding, correcting and limiting orientation during the docking process of the plug-in sleeve 7 and the plug-in block 6.

[0067] Furthermore, the cooperation between the guide rod 27 and the guide hole 28 can correct the docking trajectory of the insertion sleeve 7 in real time, avoid deviation during docking, ensure the precise alignment of the limiting rod 24, tilting rod 20 and other mating components, reduce assembly difficulty and improve assembly success rate.

[0068] Furthermore, the guide structure provides a precise motion reference for the entire secondary positioning process, preventing misalignment of the mating components. At the same time, the tight fit between the guide rod 27 and the guide hole 28 can further enhance the connection strength between the plug block 6 and the plug sleeve 7, and help improve the overall stability of the positioning structure.

[0069] In this invention, the operator assembles the required cutting blade onto the mounting rod 4, determines the installation position of the cutting blade, and then secures it firmly using the matching locking components. Next, the mounting rod 4 is moved above the placement opening 3 on the frame 1, aligning the locking grooves 5 at both ends of the mounting rod 4 with the arc-shaped protrusions 8 on the inner wall of the placement opening 3. The mounting rod 4 is then slowly lowered, allowing the locking grooves 5 and the arc-shaped protrusions 8 to engage. After the two are firmly engaged, the arc-shaped plate 9 hinged to the arc-shaped protrusion 8 is flipped over, and the arc-shaped plate 9 is embedded into the locking grooves 5. Simultaneously, the magnetic snap 11 on the arc-shaped plate 9 is embedded into the first magnetic groove 10 on the arc-shaped protrusion 8, forming a magnetic attraction, thus completing the initial positioning of the mounting rod 4.

[0070] After initial positioning is completed, the electric track 12 on the control frame 1 is activated, driving the connecting frame 13 to move, which in turn moves the insertion sleeve 7 on the connecting frame 13 closer to the insertion block 6 at the end of the mounting rod 4. As the insertion sleeve 7 continues to extend, the inclined rod 20 on the insertion block 6 is inserted into the insertion port 21 on the insertion sleeve 7. At the same time, the guide hole 28 of the tapered end 15 inside the insertion sleeve 7 cooperates with the guide rod 27 inside the insertion block 6 to form a directional guiding structure, ensuring that the insertion sleeve 7 and the insertion block 6 are accurately connected.

[0071] In this docking state, the limiting rod 24 inside the plug-in block 6 is adapted to the sliding groove 16 on the conical end 15. As the conical end 15 continues to penetrate deeper, the limiting rod 24 is squeezed by the conical surface, compressing the spring 23 inside the circular through hole 22, and extending outward along the circular through hole 22, finally allowing the end of the limiting rod 24 to be inserted into the limiting insertion hole 25 of the plug-in sleeve 7, achieving radial limiting. Subsequently, the rotating rod 14 on the plug-in sleeve 7 is rotated to switch the double-sided magnetic suction rod 19, which is in the first working area, to the second working area, so that the double-sided magnetic suction rod 19 is magnetically fixed to the corresponding side of the second magnetic suction groove 18. When the rotating rod 14 drives the conical end 15 to rotate synchronously, the end of the limiting rod 24, which was originally located in the sliding groove 16, will be inserted into the positioning notch 26 on the conical end 15, completing the locking of the limiting rod 24, thus completing the overall assembly and fixing of the mounting rod 4.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
