Leather splitting is a crucial process in the modern leather industry. Its primary purpose is to separate a whole piece of leather into layers of varying thicknesses, such as top and split, to meet the material performance and cost requirements of various products. The key to achieving high-quality splitting results lies in ensuring uniform leather thickness during processing. This not only directly impacts leather utilization and product quality, but also ensures smooth subsequent processing.1. Precision Mechanical DesignThe core of the Shengma leather splitting machine lies in its precise mechanical structure. The equipment typically utilizes a high-strength cast iron or steel frame, ensuring no deformation or vibration during long-term operation, providing a foundation for stable processing. The gap between the upper and lower pressure rollers and the knife roller can be precisely adjusted, typically through a CNC system or manual fine-tuning device, with a minimum adjustment accuracy of 0.01 mm. This high-precision gap control directly determines the thickness consistency of the leather after splitting. Furthermore, the blade roller is made of high-hardness alloy steel and dynamically balanced to ensure smooth, non-jumpy rotation and avoid uneven cutting due to vibration.2. Advanced Automatic Thickness Control SystemModern high-end Shengma leather splitting machines are commonly equipped with an automatic thickness control system. This system uses high-precision sensors to monitor the raw thickness of the incoming leather in real time and feeds this data back to the control system. Based on the preset target thickness, the control system automatically adjusts the position of the upper pressure roller or blade roller to dynamically compensate for variations in leather thickness. For example, if the sensor detects a thicker section of leather, the system instructs the actuator to slightly lower the blade position to ensure a consistent thickness of the split leather. This closed-loop control mechanism significantly improves processing accuracy and is particularly suitable for situations where raw material thickness fluctuates significantly.3. Stable Tension and Feeding SystemThe leather must be flat and evenly stressed before entering the splitting area. To this end, the splitting machine is equipped with a constant tension feeding device. This system uses a pneumatic or servo motor-driven tension roller to apply a stable, adjustable tension to the leather, preventing wrinkling, sagging, or shifting during operation. Stable tension not only helps the leather pass smoothly through the blade but also reduces cutting errors caused by uneven local force. Furthermore, the feed speed can be precisely controlled to ensure a consistent length of leather passing through the blade per unit time, preventing speed fluctuations from affecting splitting quality.4. Efficient Tool System and Sharpening DeviceThe sharpness and stability of the tool are key factors in determining even splitting. Blunt or worn blades increase cutting resistance, easily causing leather tears or thickness variations. Therefore, high-quality splitting machines are often equipped with automatic sharpening devices that allow for in-process sharpening of the blades during operation or during continuous operation, ensuring a consistently sharp edge. Furthermore, the tool mounting structure is well-designed, offering excellent rigidity and vibration-absorbing properties, effectively preventing vibration during cutting, thereby ensuring a smooth, consistent cross-section.5. Intelligent Operation and Data ManagementWith the advancement of industrial automation, many Shengma leather splitting machines have integrated touchscreen interfaces and data storage capabilities. Operators can pre-set processing parameters for different leather types, and the machine automatically calls the corresponding program, reducing human error. The system also records processing data for each batch, facilitating quality traceability and process optimization. Some equipment also supports remote monitoring and fault diagnosis, further enhancing the intelligent level of production management.In summary, the Shengma leather splitting machine utilizes multiple technologies, including a precise mechanical structure, automatic thickness control, stable feeding, an efficient tool system, and intelligent management, to fully ensure uniform leather thickness during processing. This not only improves product quality and raw material utilization, but also provides strong support for tanning companies to achieve efficient, energy-saving, and sustainable development.
