In the modern leather processing industry, efficient and precise utilization of natural leather resources is crucial for increasing product added value and production efficiency. As a core piece of leather post-processing equipment, the Shengma leather splitting machine is responsible for scientifically separating the entire raw hide into layers according to thickness requirements. In particular, achieving this "beautiful separation" between the top and second layers requires precise technical precision and process control, which directly impacts the quality and intended use of subsequent products.1. Pre-Separation Preparation: Raw Material Handling and RehumidificationBefore entering the splitting machine, leather must undergo a series of pretreatment steps. Freshly tanned leather is typically hard and has uneven moisture content. Direct splitting can easily result in uneven thickness or tearing. Therefore, rehumidification is first required to fully soften the fiber structure and restore a certain degree of flexibility and plasticity. This step is typically accomplished through soaking, spraying, or steam conditioning to ensure consistent moisture content throughout the entire hide. The leather also needs to be stretched and flattened to remove wrinkles, ensuring smooth transport during the splitting process and preventing local deformation that could affect cutting accuracy.2. Core Structure and Working Principle of the Splitting MachineThe Shengma leather splitting machine primarily consists of a feeding system, a clamping device, a rotary blade, a thickness adjustment mechanism, and a receiving system. Its core operating principle is to utilize a high-speed rotating annular or circular blade to continuously and evenly cut the leather horizontally while it is moving, under constant pressure. The feeding system smoothly feeds the leather into the cutting area via a conveyor belt or rollers, while the clamping device ensures that the leather does not shift or wrinkle during the cutting process.The most critical components are the rotary blade and the thickness adjustment mechanism. Modern splitting machines generally utilize a servo motor-driven CNC adjustment system that precisely controls the gap between the blade and the support roller, thereby setting the desired layer thickness. For example, if a 0.8mm top layer is required, the system automatically adjusts the blade position to ensure the cut surface is precisely located at the junction of the top and second layers, achieving a "one-cut, one-cut" effect.3. Key Technologies for Achieving "Beautiful Layering""Beautiful layering" refers not only to physical separation but also emphasizes the smoothness and thickness consistency of the layered surfaces, as well as minimal damage to the fiber structure. To this end, modern splitting machines utilize several advanced technologies:Automatic Thickness Detection and Feedback System: This system uses an infrared or laser thickness gauge to monitor leather thickness in real time, feeding this data back to the control system, dynamically adjusting the tool position to accommodate thickness variations in different areas of the leather.Constant Pressure Clamping Technology: This system utilizes a pneumatic or hydraulic clamping device to ensure uniform pressure throughout the cutting process, preventing rough or offset cut surfaces caused by pressure fluctuations.High-Precision Tool Material and Sharpening: This system utilizes carbide or ceramic blades, coupled with an automatic sharpening system, to maintain a sharp edge, reduce frictional heat and fiber tearing, and enhance the smoothness of the layered surfaces.4. Subsequent Processing and Application of Top and Second LayersAfter successful separation, top-layer leather, with its intact surface and distinct grain, is often used in high-end leather shoes, handbags, car seats, and more. Second-layer leather, on the other hand, can be modified through processes such as lamination, spraying, and embossing, and is widely used in mid-range furniture, clothing, and footwear. The precise splitting of a splitting machine allows a single piece of leather to be used for multiple purposes, significantly improving resource utilization and economic efficiency.The Shengma leather splitting machine is more than just a mechanical cutting tool; it embodies the intelligent and sophisticated nature of the modern leather industry. Through sophisticated mechanical design, advanced sensing technology, and automated control, it achieves "gorgeous separation" of the top and second layers, maximizing the value of each piece of leather.
