Inspection and preparation before the cutting machine is turned on
4.1.1. Confirm that the main power supply voltage is 380V.
4.1.2. Turn on each power switch and check if the electricity and gas supply are normal.
4.1.3. Before starting the machine, you must confirm that the surface of each guide roller is smooth and free of burr dust, debris, etc. When cleaning the machine, use alcohol or water to soft cloth.
Wipe, can not be wiped with other solvents, remove the impurities around the equipment and production, to ensure normal production;
4.1.4. Obtain all kinds of accessories and tools such as slitting products and tapes in strict accordance with the production instruction sheet and the process card requirements.
18.104.22.168. Receive the composite film specified on the production instruction sheet, check whether the composite film tracking card is complete, and describe the previous quality problem is it clear.
22.214.171.124. Confirm the cut specifications, roll direction, batch number, material structure, winding diameter or meter number according to the production order. 4.1.5. Carefully check the equipment to confirm that each rewinding mechanism, EPC device, and tension control system are normal, and confirm static electricity.
Whether the elimination is normal or not;
4.1.6. The unwinding material is ready, and then the film is routed in the correct way;
4.1.7. Prepare the winding paper core according to the slitting specifications and place it in the corresponding position of the winding reel.
The basic knowledge of the slitting machine and its development process --
Basic knowledge and development of slitting machine
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. Actually, I think that the efficiency of the slitter is related to the following factors: slitting speed, finished product. Rate, non-operation time, stability, etc. Although the cutting speed is an important indicator of the working efficiency of the slitting machine, if the yield is low, not only will the work efficiency of the whole machine be low, but also the cost will increase. Similarly, if the non-operation takes a long time, such as: adjusting the machine, setting the tool, changing the tool, refueling, connecting the joint, changing the volume, processing the problem, etc., it takes a long time to improve the speed of the slitter, and it makes no sense. It is. Not to mention the stability of the slitting machine, not only will it affect the working efficiency of the slitting machine, but also affect the quality of the product, and it will cause trouble and unnecessary waste to the next process. Therefore, the efficiency of the slitter is a comprehensive concept.

3. Lack of insight into the characteristics of different materials at the time of slitting, distinguishing between control systems and structures
Everyone knows that the physical properties of different materials are inconsistent. Some materials are smooth and firm. Some materials are very soft and soft, and the physical properties of the same material with different thicknesses are not the same. Among the slitting machines, the structure is also different, and there is a lack of changes in the control system due to its structural changes. The difference is rarely studied. In particular, the change in the difference in the control curve is even less known, and its mature control system software is still very few in China. Although some people have tried the application of a slitter control software, the chances of success are very low. Most of them are characterized by “headaches and pains.” Although our company has experienced 7-8 years of hard work, Some experience has been gained and the control system is becoming more mature, but there is still a certain gap compared with the materials covered by well-known foreign brands.
