Reasons, countermeasures and effects of BOPP film slitting quality ---
Another reason for the burrs is the quality of the parent roll.
First, when the mother roll product is wrinkled, the burr phenomenon is likely to occur when the film is cut to the sipe roll and the film is not effectively flattened;
Second, when the film is thick or thin for a long time, the film is prone to burr phenomenon when the film is not attached to the sipe, especially in the triangular position of the thickness. In addition, since the thinner the film, the lower the stiffness, and the higher the chance of burrs.
Slitting machine operation guide ---
8.1 The cutting personnel shall record the production status in the “production record of the cutting machine” and other related records, insert the product into the “product tracking card”, and fill in the corresponding content in time according to the column and frequency requirements set in the record. The disk customers fill in the theoretical weight of each product for the weight of the product label of the Xiamen Cigarette Factory (see the attached table for the theoretical weight of each product), and the content is complete, clear, true and accurate.
8.2 Records should not be filled in with a pencil. The record holder should sign the quality record and indicate the time the record was filled.
8.3 The records listed in the record (except the remarks column) should be filled in. If the corresponding content is not found or there is no item, it can be recorded by slashing. The operator should write the full name and must not only write the last name.
8.4 Record changes caused by mistakes, etc. shall not exceed three pages per page. The records shall be clearly identifiable after the change. For all kinds of quality records that are validated and validated by the product and system, the change shall be stamped with a proofreading or marked change. people.
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:
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.
