1. Slitting machine should cut whole roll or whole raw material with fixed length, such as plastic packaging material, packaging carton, steel plate, film, leather, wood chips, etc. It must use fixed length slitting control.
2. Fixed-length slitting control is divided into static and dynamic slitting control: accurate shutdown when the set length arrives, then static slitting processing, restart operation after slicing; when the set length arrives, non-stop slitting signal is sent out, and dynamic slitting processing is carried out in the course of material movement.
3. The most important performance index of fixed-length slicing is the accuracy of slicing, and the consistency of finished product length is good.
4. The cutting length can be set continuously. If the actual cutting length has errors, it is easy to calibrate by setting parameters.
Not only the slitter has the operation process requirements, but also the rewinder and napkin paper machine have the corresponding process requirements. Every operator of these machinery and equipment should carry out these training before going to work, so as to reduce the probability of accidents. In production and processing, whether manual or mechanical operation, we pay more attention to its work efficiency, because good efficiency can not only improve the productivity of the processing and manufacturing side, but also save costs. Therefore, when purchasing the slitter, we pay more attention to its performance and quality. However, when it comes to the efficiency of the slitter, many people think that the efficiency of the slitter is only related to the speed of the slitter. In fact, otherwise, I think that the efficiency of the slitter is related to the following factors: slitting speed, yield, non-operational occupancy time, stability and so on. Slitting speed is an important indicator of the efficiency of the slitter, but if the yield is low, not only the efficiency of the whole machine will be low, but also the cost will rise.
Similarly, if the non-operation takes a long time, such as: adjusting machine, knife alignment, knife change, material change, joint, roll change, problem handling, etc., it will be meaningless to simply increase the speed of the slitter. Not to mention the stability of the slitter, it will not only affect the efficiency of the slitter, but also affect the product quality, and will cause trouble and unnecessary waste to the next process. So the working efficiency of the slitter is a comprehensive concept.
