Chopping, No Burrs! Science Popularization Of Tension Control System For High-Speed Splitter

In the film, paper, non-woven cloth, tape and other various kinds of winding cutting processing, the the finished cut smoothness, burr existence, winding regularity is the core standard to measure the quality of products. Many production lines have defects such as cutting burr, roller tensile deformation, width size deviation and crease during winding. Many people mistakenly think this is due to a lack of precision in the tool, but in fact most of the quality problems are due to unstable tension control. The tension control system of high the high-speed slitting machine is the core control module of the equipment, which directly determines the precision of slitting and the quality of the finished product. This is also the key configuration that distinguishes high-end high-speed slitting machines ordinary simple slitting equipment. Stable tension control is the core guarantee of high speed cutting, smooth end surface and zero burr processing.
The intelligent constant tension control system equipped with high the high-speed slitting machine adopts the logic of closed loop intelligent adjustment, which completely solves the drawbacks of traditional mechanical force control. The system can monitor the tension and running speed of the coil in three stages: unwinding, intermediate conveying and winding. The damping force and winding speed can be adjusted dynamically through the cooperation of servo motors, sensor and intelligent controller. Whether the equipment is in low speed test, high speed mass production or starting and stopping the transmission, it can always maintain uniform force and stable tension of the coil, eliminate all kinds of processing defects caused by tension fluctuations, and adapt to the conditions of long-term continuous high speed production.
Accurate tension control is the key to burr-free cutting. Vertical and sharp cutting can be achieved in the process of sectioning by means of high speed precision cutting tool. If the tension is unstable, the roll material will shake, loosen and shift, and the cutting tool will scratch, strain and shift during cutting process, resulting in uneven cutting, blurred edges and local tearing, especially in easily deformed materials such as film, tissue paper and soft non-woven fabrics, where burrs and defects are more noticeable. The constant tension system can stabilize the operation of the coil and smooth the material through the blade group at a constant speed. The blade cuts through the material fibers vertically and cleanly, with a smooth, even cut that removes burrs, edges and tears from the roots.
At the same time, the tension control system can adjust parameters according to different materials, thickness, coil width and so on. For different materials such as high-toughness film, high-weight paper, fluffy non-woven cloth, tape, etc., the system can accurately match the corresponding tension values, flexibly adapt to material characteristics and avoid one-size-fits-all control. Low tension of thin material, gentle conveying, prevent tensile deformation; increase the tension of thick material appropriately, ensure smooth transportation without shaking, balance cutting accuracy and material integrity, and improve the overall qualification rate finished products.
In addition to optimizing cutting appearance, stable tension control can significantly improve winding quality and production stability. In the winding process of cut coil, the problems of uneven elasticity, uneven end surfaces and bulging edges are most likely to occur. The core reason is the mismatch of winding tension. The high-speed slitting machine adopts a segmented tension adjustment mode, synchronous linkage, and gradient adaptation to unwinding, conveying, and winding tension. The stress of the whole winding process is uniform, the finished coil is compact and smooth, the end surface is clean, no loosening, wrinkling, deformation. Not only does it have a excellent texture on the outside, but it's also easier to store, transport and secondary process later on.
In conclusion, tension control system is the core of the quality of high-speed slitting machines, which directly affects the precision, phase and stability of coil slitting. Through intelligent constant tension control, the pain point of traditional slitting equipment such as burr, large deformation, poor accuracy and winding disorder is solved completely, and the two-way balance between high speed production and high quality cutting is achieved. Accurate and stable tension control is the core guarantee to achieve zero burrs, high flatness and high precision in the precision processing and production of high quality coils. It is also the indispensable core technical advantage of modern high-speed slitting equipment.
