Description

Technical Field

[0001] This utility model relates to the field of decorative leather processing technology, specifically to a cutting device for processing antique-effect decorative leather. Background Technology

[0002] In the field of antique-effect decorative leather processing, the precision and efficiency of the cutting process directly affect product quality and production costs. However, traditional leather cutting equipment has several technical defects: the leather fixing method is singular, relying only on mechanical clamps or simple negative pressure adsorption. During cutting, the material is prone to expansion and contraction and sliding, leading to cutting deviations. This is especially true for antique-effect decorative leather with complex surface textures and easy deformation, where displacement problems are more pronounced. The material feeding stage lacks real-time tension monitoring and closed-loop control, resulting in large fluctuations in leather tension, which can easily cause breakage or loosening and affect the continuity of cutting. Laser cutter path calibration relies on manual adjustment and cannot adaptively adjust parameters such as power, speed, and focal length according to material thickness, making it difficult to guarantee cut smoothness and dimensional accuracy. Waste disposal is inefficient, with scrap cleaning relying on manual labor. Dust accumulation can easily contaminate the equipment, and the negative pressure system lacks filtration design, resulting in exhaust emissions that do not meet environmental protection requirements. The degree of automation is low, lacking an integrated monitoring interface and data recording function. Parameter adjustment relies on experience, resulting in low troubleshooting efficiency and difficulty in achieving quality traceability for large-scale production. In view of this, in-depth research was conducted to address the above problems, leading to this case. Utility Model Content

[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0018] Please see Figure 1-5 In the processing of antique-effect decorative leather, the precision and efficiency of the cutting process directly affect product quality and production costs. Traditional leather cutting equipment typically suffers from the following technical shortcomings: Unstable leather fixation: Relying solely on mechanical clamps or single negative pressure adsorption, cutting deviations are easily caused by the stretching and sliding of the leather during cutting. This is especially true for materials with complex surface textures and easy deformation, such as antique-effect decorative leather, where displacement problems are more pronounced.

[0019] Coarse tension control: The lack of real-time tension monitoring and closed-loop control during the feeding stage leads to large fluctuations in leather tension, which can easily cause breakage or loosening and affect the continuity of cutting.

[0020] Limited cutting accuracy: Laser cutter path calibration relies on manual adjustment and cannot adaptively adjust parameters (such as power, speed, and focal length) according to material thickness, making it difficult to guarantee cut smoothness and dimensional accuracy; Therefore, this application protects a cutting device for processing antique-effect decorative leather. Two pairs of hydraulic chucks 3 clamp the feeding shaft and the collecting shaft. A feeding drive motor rotates the hydraulic chucks 3, thereby rotating the collecting shaft and stably stretching the leather on the feeding shaft. The processing bracket 2 and the longitudinal and transverse guide rails 4 on the concave transport block 1 move, driving the movable limiting plate 5. The movable limiting block is positioned at the upper and lower ends of the leather. Two pairs of lifting hydraulic push rods 6 on the movable limiting block extend and retract, driving the lifting limiting plate 7 on the pushing end. Simultaneously, two pairs of concave limiting blocks 8 on the lifting limiting plate 7 perform a U-shaped compression limiting on the leather processing area. A negative pressure pump 11 operates, directing the cross-shaped negative pressure pipe 10, two pairs of negative pressure L-shaped drainage pipes 9, and two pairs of concave... The air inside the limiting block 8 is discharged. After the leather is squeezed in a U-shape, the squeezed area is subjected to negative pressure adsorption and limiting, which avoids displacement due to shaking during cutting. Similarly, the cutting guide 12 drives the set groove block 13 on it for fine-tuning cutting. The lifting ring electromagnet 19 inside the lifting slide 15 is energized, which magnetically repels the lifting ring magnet 18. The lifting ring magnet 18 drives the lifting slider 16 on it, so that the lifting slider 16 moves stably along the inner side of the lifting slide 15. The lifting slider 16 drives the lifting blocking U-shape block 20 on it. Multiple lifting moving balls on the lifting blocking U-shape block 20 perform flexible compression and set cutting on the cut. At the same time, the relative expansion and contraction of multiple lifting moving balls limit the leather. In summary, this antique-effect decorative leather cutting equipment achieves efficient and precise processing through multi-stage collaborative operation. Its operating process and core principle can be summarized as follows: In the feeding stage, two pairs of hydraulic chucks 3 clamp the feeding shaft (raw material) and the collecting shaft (finished product) respectively. Driven by a feeding drive motor, the leather is smoothly stretched from the raw material shaft to the processing area. This stage integrates real-time tension monitoring and closed-loop control technology. Data is collected by a tension sensor and processed by a PLC. A PID algorithm dynamically adjusts the drive motor speed to ensure constant leather tension and prevent tension fluctuations from affecting cutting accuracy. Subsequently, the equipment enters the limiting and negative pressure adsorption stage. Mechanical limiting is achieved by driving the moving limiting plate 5 to the upper and lower surfaces of the leather via longitudinal and transverse guide rails 4. Combined with the lifting hydraulic push rod 6, the lifting limiting plate 7 is pushed, causing the concave limiting block 8 to form a U-shaped extrusion structure, initially fixing the processing area. Simultaneously, the negative pressure adsorption system is activated. The negative pressure pump 11 discharges air through pipes to create a negative pressure environment, adsorbing the leather surface to further prevent displacement. The design emphasizes flow field optimization (using a short path, fewer bends) and is equipped with a multi-stage filtration system (such as HEPA filter + cyclone separator), with regular cleaning and maintenance to ensure adsorption stability. During the cutting stage, the laser cutter cuts along a preset path, while a flexible limiting structure driven by electromagnetics achieves precise fixation. When the lifting ring electromagnet 19 is energized, it repels the ring magnet 18, driving the lifting shielding block 20 to descend. Multiple pairs of lifting moving balls on it form a flexible extrusion surface, dispersing pressure and preventing material deformation. Cutting parameters (such as laser power, speed, and focal length) can be adaptively adjusted according to the leather thickness, and the path is optimized through trial cutting to ensure cut smoothness and dimensional accuracy. After cutting, the finished product is wound up by the collection shaft, and the feeding shaft releases new raw materials simultaneously. Waste is blown into the waste bin by the blowing assembly and cleaned regularly. The equipment is also equipped with a human-machine interface that integrates parameter settings, real-time status monitoring, and fault alarm functions. It also records processing data to generate reports, supporting quality traceability and process optimization. Its core advantages lie in its multi-dimensional limiting system (mechanical extrusion + negative pressure adsorption + flexible extrusion) to achieve omnidirectional fixation, significantly improving cutting accuracy; intelligent parameter adaptive technology reduces manual intervention; the negative pressure system integrates activated carbon filtration and fan frequency conversion control, taking into account both environmental protection and energy saving; the modular design facilitates quick component replacement to adapt to different specifications of processing needs, and the overall technology reaches the industry-leading level, suitable for the large-scale production of high-precision antique effect decorative leather.
