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.
1. The effect of deviation on usage
The effect of deviation on the use is basically the same as that of the end face, which is mainly to track the problem of alignment and the influence on the appearance of the product. Because the degree of misalignment of the deviation is much more obvious than that of the end face, it does not meet the requirements of the customer. Therefore, it must be processed twice, and it can be graded and packed into the warehouse after meeting the requirements.

4 operational requirements
4.2.6 The customer is the product of Xiamen Cigarette Factory, and the length of the reel is cut. The weight of the reel label is filled in the theoretical weight of each product (see the attached table for the theoretical weight of each product). After the self-inspection is passed, the scale needs to be scaled one by one. The weight of the product is kept rounded to two digits after the decimal point. The weight of the product registered in the certificate and machine record table should be consistent, and the record should be true and accurate.
4.2.7 The products that have passed the self-test and the internal and external labels are neatly stacked on the tray. The number of products stacked on each tray and each tray is specified in the “Product Printing Process Card” and fixed with a cannula.
4.2.8 If the product does not meet the quality requirements, it needs to be removed or the product quality is in doubt. It is necessary to carry out re-inspection and strictly follow the “Rewinding Machine Operation Guide”.
4.2.9 Timely labeling and isolating materials, products, and materials to be processed at the production site, and taking the squad leader in charge of process identification and traceability operation control and integrated management according to the “identification and traceability control procedures”. After each shift is completed, the production report should be taken to the monitor.
4.2.10 If the product to be treated has not been processed within 2 working days, it should be reported to the workshop with the squad leader for timely disposal.
4.2.11 When the cutting machine is changed, it must be strictly in accordance with the “Regulations on the Management of Shop Closing”.

three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
3. Manufacturing: This is a common problem faced by China's manufacturing industry. Everyone knows that any mechanical equipment, besides being reasonable in design, requires precision in manufacturing, and Chinese manufacturing is lacking in this respect. The manufacturing process is also a weak link. In addition to some general-purpose machine tools, there are some special equipments for manufacturing slitting machines, such as dynamic balancing machines, water cutting machines, etc., due to the manufacturing precision requirements of the slitting machine. High, therefore, some equipment needs to use CNC machine tools to process parts, especially the need to popularize the machining center, so that the processing precision of the equipment that produces the slitting machine can be fundamentally guaranteed.
