Shengma leather splitting machines are widely used in the leather processing industry. Ensuring the smoothness of the cut during the cutting process is one of the core performance indicators. Cut smoothness not only affects the appearance quality of leather products but also directly impacts the efficiency of subsequent sewing and laminating processes. Achieving this requires comprehensive control from multiple dimensions, including equipment precision, blade performance, process parameters, and operating procedures.
Blades are a key factor determining cut quality. Shengma leather splitting machines require high-precision, highly wear-resistant specialized blades. For example, blades made from micron-level cemented carbide can achieve micron-level sharpness, effectively reducing frictional resistance during cutting and preventing tearing or pulling of leather fibers. Simultaneously, the parallelism of the blades must be strictly controlled. If the blades are tilted or bent after installation, it will lead to inconsistent cutting depths, resulting in uneven cuts. Therefore, regularly checking blade wear and replacing them promptly is fundamental to ensuring cut quality.
The precision and stability of the equipment itself are equally important. The guide rail system of a shengma leather splitting machine must possess high straightness and a low coefficient of friction to ensure smooth, vibration-free movement of the blade holder during cutting. Wear or installation misalignment in the guide rail will cause the blade holder's trajectory to deviate, resulting in wavy or serrated edges on the cut. Furthermore, the synchronization of the transmission system requires close attention; the speed difference between the main shaft and driven shaft must be controlled within a minimal range. Otherwise, inconsistent speeds will cause the leather to stretch or compress, affecting the smoothness of the cut.
Optimizing process parameters is crucial for improving cut quality. Cutting speed needs to be adjusted specifically according to the leather thickness and material. For example, for thicker or more resilient leather, the cutting speed should be appropriately reduced to decrease frictional heat between the blade and the leather, preventing melting or deformation of the leather edges due to overheating. Controlling the cutting pressure is equally critical. Insufficient pressure will result in incomplete cutting, leading to burrs or adhesion; excessive pressure may cause over-compression of the leather, thinning the cut edges or even causing them to crack. Therefore, the optimal pressure range must be determined through experimentation and maintained consistently during cutting.
The method of securing the leather directly affects the smoothness of the cut. A shengma leather splitting machine needs to be equipped with an efficient clamping device, such as a vacuum suction platform or pneumatic clamping mechanism, to ensure the leather is completely fixed during cutting, preventing cut deviation due to leather movement or vibration. For leather with uneven surfaces, pretreatment is necessary before cutting, such as ironing or spraying adhesive to smooth the surface and reduce stress concentration during cutting.
The skill level of the operator is also a crucial factor. Operators must undergo professional training and be familiar with the equipment's operating procedures and precautions. For example, when changing blades, ensure the blade is installed in the correct direction to avoid increased cutting resistance due to reversed blade installation; when adjusting process parameters, follow the principle of "slow first, then fast; light first, then heavy," gradually optimizing the parameter combination. Furthermore, operators must possess troubleshooting skills to promptly identify and resolve abnormalities during cutting, such as rough edges, breakage, or scorching.
Equipment maintenance is fundamental to ensuring long-term cutting quality. Shengma leather splitting machines require regular cleaning, lubrication, and calibration. For example, daily cleaning of dust and leather debris from the guide rails and transmission components is necessary to prevent increased resistance due to impurities. The blades should be sharpened or replaced weekly to ensure they remain sharp. A comprehensive calibration of the equipment should be performed monthly, including key indicators such as guide rail straightness and transmission synchronization, to ensure the equipment is always in optimal working condition.
