What is a slitting machine? How is slitting?

Slitting machine is a kind of mechanical equipment that divides wide paper, Mica tape or film into multiple narrow materials. It is commonly used in papermaking machinery, wire and cable Mica tape and printing and packaging machinery. Slitting machine is mainly used in: Mica tape, paper, insulating materials and film slitting, especially suitable for narrow band (Insulation Materials, Mica tape, film, etc)The slitting. Classification of slitting machines: 1. According to the structure, there are vertical slitting machines, horizontal slitting machines, surface center coiling slitting machines and gantry slitting machines. Second, according to the materials, there are film slitting machines, paper slitting machines, cloth slitting machines, leather slitting machines, copper and aluminum foil slitting machines, etc. Third, according to the degree of automation, there are microcomputer-controlled manual tension slitting machines and computer PLC automatic tension slitting machines. Fourth, according to the speed, there are low-speed slitting machines (Mechanical speed less than 160 per minute), Medium speed slitting machine (Mechanical speed 180-200 m/min), High speed slitting machine (Mechanical speed above 300 per minute) Principle 1. paper slitting machine to the whole roll or the whole sheet of raw materials for fixed length slitting processing, such as plastic packaging materials, packaging carton, steel plate, film, leather, wood chips and other slitting processing, both need to use fixed-length slitting control. 2. The slitting length can be set continuously. If the actual slitting length has errors, it is easy to calibrate by setting parameters. 3. The slitting control of paper slitting machine is divided into static and dynamic slitting: Stop the Machine accurately when the set length is reached, then the static slitting process, and restart the operation after slitting; When the set length of the trimming machine reaches, the slitting signal is sent out without stopping the machine, and the slitting machine is dynamically slitting in the process of material movement. Computer slitting machine is a kind of important equipment often used before and after printing. It mainly cuts raw materials before printing, such as paper and plastic film. This is a process that raw material manufacturers must complete in order to meet the width requirements of packaging manufacturers such as customers. However, the slitting process after the most widely used printing and compounding uses a slitting machine to slitting the printing of multiple sets of patterns with fixed width and the composite film into finished film rolls to adapt to the automatic packaging and bag-making processes behind. With the improvement of flexible packaging automation and the focus of consumer goods manufacturers on reducing the inefficiency and pollution of intermediate links, some manufacturers have gradually changed their technological processes to replace manual packaging with automatic packaging lines with a higher degree of automation. With the increasing demand for coiled materials, the status of slitting machine is becoming more and more important, which puts forward higher requirements for the working efficiency of slitting machine.
