Reasons, countermeasures and effects of BOPP film slitting quality ---
Deviation refers to the phenomenon that part of the film on the end face of the film roll is misaligned, which is caused by the sliding of the film during the winding process.
2. Causes and countermeasures of deviation:
(1) The problem of the quality of the slitting in the same category as the deviation of the end face is, in terms of degree, the degree of misalignment is more serious than the misalignment of the end face; in terms of nature, the general end face is not a continuous problem. However, the deviation is mostly an accidental problem; from the analysis of the reasons, the cause of the unevenness of the end face may cause the occurrence of the deviation problem.
(2) Since the deviation of the deviation from the end face is more prominent, the eye point should be placed in the fine point when the end face is not aligned. When analyzing the deviation problem, the eye point should be widened, especially the factor of the cutting speed. The effect is that the acceleration and deceleration are too rapid. For a film with good smoothness, it is easy to cause slippage and cause a split layer, and the slitting speed should be slowed down.
(3) For products with narrow slitting, too tight winding of the film roll will cause the film to slip laterally. If the film roll is too loose, air will be trapped, which will cause the film roll end to be staggered. Roll tension.

6 Safety Precautions
6.1 The operator must be trained to work and wear the labor protection products correctly; carefully check the protective devices, safety interlocks, test buttons, emergency buttons, etc. of the machine before starting the machine, and confirm that the machine can be turned on after normal operation.
6.2 The slitting machine is a double-operated equipment. It is forbidden to operate in tandem, especially when the equipment is repaired.
6.3 The cut products should be stacked neatly and securely, and fixed with a cannula to prevent the product from slipping and hurting people.
6.4 When working, it is not allowed to place any irrelevant items such as oil pots and tools on the workbench.
6.5 During the operation of the machine, it is strictly forbidden to reach into the circumference of the slitting knife or the pressure roller. Even if the vehicle has been stopped but the power is not disconnected, it is forbidden to perform the tool change, paper adjustment and adjustment under the knife.
6.6 Slitting blades must be protected during handling and storage, and must not be handled or stored with bare edges.
6.7 The interlocking protection devices of all parts of the equipment shall not be short-circuited or removed, and if malfunction or abnormality occurs, stop immediately and report to the machine for repair and maintenance.
6.8 Machine personnel shall not perform fault repair or equipment adjustment of fault type, and the power distribution cabinet, switch box, etc. shall not be opened without authorization, and shall not store items.
6.9 When handing over the shift, you must hand over the site, and you must explain the production and equipment operation of the class to the next one.
6.10 Check the surrounding conditions before leaving work, and cut off the power and air supply of the machine and related equipment.
Domestic cutting machine development status and outlets ---
three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
1. Frame structure: Whether it is a slitting or a second or third slitting, domestic slitting machine manufacturers should invest their energy and study on the frame structure, and actually design a more reasonable slitting machine to get rid of the cutting machine manufacturers. At present, the plagiarism of the slitting machine produced, the research and design of a personalized slitting machine, making the different materials in the structure more detailed, in the next round of international market competition, to provide a favorable weapon for film-making enterprises, At the same time, I also find out the blue ocean for my own company.
