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.
core.
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.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

(3) Causes of loose/overtightening of the film roll
1. The influence of the cutting parameters (winding sheet / pressure curve setting factors, etc.);
2. Effect of film properties (stiffness, thickness, single/double corona surface, smoothness, static electricity, etc.)
Ringing, the slitting parameters must be set according to the film with different characteristics);
3. The effect of the winding speed (when the winding speed is slower, the more time the slitting process is to discharge the air in the film roll, the tighter the film winding is);
4. Product specifications (width, length, collocation, etc.);
5. The influence of the performance of the slitting equipment (adjustability, stability, operability, etc.);
6. The influence of operational factors (professional level, operational skills, job responsibility, etc., generally expressed in the insertion
7. The quality of the work is wrong, such as poor air-suction, rewinding card head position, poor adjustment, and unwinding roller pressure; The influence of environmental factors (temperature, humidity, etc.);
8. Influencing factors of the appraisal system (Operator considers the appraisal of the secondary processing and rewinding indicators in the workshop, and often adopts the coping method of winding up and not loosening, which is one of the factors that cause the film roll to be over-tightened);

Reasons, countermeasures and effects of BOPP film slitting quality ---

nine. Scratch
      Whether the slitting and scratching can be compared and determined by the film surface before and after the slitting, there are various reasons for the scratching of the membrane surface, and the analysis should be based on the appearance of the scratch, such as short-line scratching. The difference of the speed ratio of each drive roller exceeds the process setting requirement, and it needs to be carefully tested and adjusted. If the film surface scratch occurs continuously, the film on the slitter should be inspected for whether it touches the fixed object or cuts each. Whether the roller adheres to dirt such as fine sand grains scratches the film surface.
Scratch is the appearance quality problem of the film, which directly affects the quality appearance of the deep-processed product. Therefore, it is not allowed to exist in the film quality control standard. The slitting process finds that the scratching problem must be carefully checked and quickly eliminated. Since the scratch on the film surface is an irreversible appearance quality problem, it is not allowed to operate the disease when the film surface is scratched, so as to avoid the continuous occurrence of the problem.
