What are the process requirements for slitting machine operation?

Technological requirements for operating the slitting machine: 1. The slitting machine shall process the whole roll or the whole piece of raw materials with a fixed length of slitting, for example, plastic packaging materials, packaging cartons, steel plates, films, leather, wood chips and other slitting processes require fixed-length slitting control. 2. Fixed-length slitting control can be divided into static and dynamic slitting: Stop the Machine accurately when the set length is reached, then process the static slitting, and restart the operation after slitting; When the set length is reached, the slitting signal is sent out without stopping the machine, and the slitting machine is dynamically slitting in the process of material movement. 3. The most important performance index of fixed-length slitting is slitting accuracy, and the length consistency of finished products is good. 4. The slitting length can be set continuously. If the actual slitting length has errors, it is easy to calibrate by setting parameters. After the aluminum foil is printed and coated, it needs to be cut on the slitting machine to cut the large semi-finished products into the required specifications and dimensions. Running the slitting semi-finished products on the slitting machine is a process of unwinding and rewinding, this process includes two parts: speed control and tension control of the machine. The so-called tension is to pull the aluminum foil and roll it on the core according to the standard. It is necessary to apply a certain stretch and tension traction to the aluminum foil, and the tension control force is the tension. Tension control refers to the ability to permanently control the tension of aluminum foil when it is transported on the equipment. This kind of control must be effective for any running speed of the machine, including the acceleration, deceleration and uniform speed of the machine. Even in the case of emergency shutdown, the saw cutting machine has the ability to ensure that the aluminum foil does not produce any damage. The tension control of slitting machine is basically manual tension control and automatic tension control. Manual tension control is to adjust the manual power supply device by the operator when the winding diameter changes to a certain stage in the process of winding or unwinding, so as to achieve the purpose of controlling tension. Not only does the slitting machine have operational process requirements, but the rewinding machine and the napkin machine also have corresponding process requirements. Each employee who operates these mechanical equipment must carry out these trainings before going to work, so as to reduce the probability of accidents. In production and processing, whether it is human or mechanical operation, we are more concerned about its work efficiency, because good efficiency can not only improve productivity for processing and manufacturing, but also save costs. Therefore, when purchasing the slitting machine, we pay more attention to its working performance and quality. However, when it comes to the working efficiency of the slitting machine, many people think that the working efficiency of the slitting machine is only related to the speed of the slitting machine. In fact, it is not the case. I think the working efficiency of the slitting machine is related to the following factors: slitting speed, yield, non-running occupied time, stability, etc. Although the slitting speed is an important indicator of the working efficiency of the slitting machine, if the yield is low, it will not only cause the working efficiency of the whole machine to be low, but also cause the cost to rise. Unwinding tension detection system of slitting machine: tension sensor detection it is a direct detection of tension, which is closely combined with machinery and is equipped with a detection method of moving parts. Usually, the two sensors are used in pairs, and they are installed on the end shafts on both sides of the detection guide roller. The material belt makes the sensitive element of the tension sensor produce displacement or deformation by detecting the applied load on both sides of the guide roller, thus detecting the actual tension value, and the tension data is converted into a tension signal and fed back to the tension controller,
