Slitting machine operating procedures -
First. When the unwinding machine normally replaces the parent roll
1. The machine is wound up and the machine speed is zero. Press the "machine off" button and all drives are turned off.
2. Press and hold the “core release” button to make the chuck exit the empty core, the empty core is placed on the unloading guide, and then the pneumatic ejector will automatically
Empty the core to the unloading position, release the button, and the steel core is to be transported away by the crane.
3. Press the “Coil Snap” button briefly to retract the cylinder rod at the unwinding position to the receiving position.
4. According to the plan, attach the corresponding mother roll to the double-sided tape, and hang the new mother roll into the V-shaped support that supports the parent roll, and hang the empty roll.
5. Press and hold the “Coil Core Clamp” button to make the card head into the new parent roll until the card head positioning pin is in place and release the button. 6. Adjust the length and diameter of the unwinder on the operation screen (correct the input value if necessary), and replace the parent roll.
Reasons, countermeasures and effects of BOPP film slitting quality ---
eleven. Width deviation is too large
The width of the film roll is limited by the gap of the sipe roll. The actual slit width will deviate from the width required for the order, but the deviation should be controlled within the tolerance range of ±2mm required by the national standard. The so-called width deviation Large, that is, the actual width of the film roll exceeds the requirements of internal control standards or customer standards.
Not all products have a tolerance of ±2mm, and some customers can only take deviations from the film width, such as the Pd film of Kunshan Zhangpu, the LL film of Shanghai Zhicheng, the PL film of Beijing Amcor, etc. It is required to adjust the film width.

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.
