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.
220.127.116.11. 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.
18.104.22.168. 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
In the process of slitting, the stable tension system is an important indicator to ensure the quality of the product. It controls the mutual tension between unwinding, drawing, slitting, winding, etc., so that the slitting material is always in the cutting process. A steady state. If the tension is properly controlled, it can avoid the deformation and drift of the raw materials during the process of speeding up and slowing down the machine. Generally, the unwinding tension is slightly larger than the sum of the reel tensions. Most of the previous slitting machines use magnetic powder clutch to control the tension, but the magnetic powder clutch speed can not be high. It is easy to cause high-speed friction of the magnetic powder during operation, which causes high temperature and shortens its life. In severe cases, it will be stuck and the machine operation will be blocked. With the development of science and technology, the use of servo drive technology, most of them now use vector variable frequency motor to control the tension system of the slitting machine. The automatic detection of the pendulum roller makes the man-machine interface intuitive, the tension system is more stable and reliable, and easy to operate.

2. Lack of composite professional talents who understand manufacturing technology and process and know cutting process
In the manufacturing process of the slitting machine, different customers are often faced with different materials and requirements. If different manufacturers produce the same materials, the raw materials used are not the same chemical plant products, and the physical properties of the materials produced are not the same. When producing the slitting machine, it cannot be generalized. In the production process, the manufacturing process will change, especially in the size of the roll diameter and the thickness of the coating layer, the difference between the active roller and the passive roller and the wrap angle of the roller surface, etc. The lack of corresponding research talents in the field often leads to many waste products and defective products in the slitting process. Such composite talents should not only be familiar with the design and manufacturing process of the entire slitting machine, but also understand the different characteristics of different materials during slitting. Currently, it is very scarce in China, which leads to the current situation of domestic slitting machines.
