Reasons, countermeasures and effects of BOPP film slitting quality ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)
With the continuous improvement of slitting technology, the length of wrinkle is becoming less and less, and the products of individual manufacturers have achieved zero wrinkle, which undoubtedly grasps the opportunities in the fierce competition environment. It is worth noting that the wrinkles that we sometimes appear are not caused by the unreasonable setting of the cutting parameters, but because our operators are not responsible for the work, and the film is not attached to the paper tube but is free. After the film is put on the paper tube, it is turned on and cut, and the quality of the wrinkle is artificially created. It must be paid attention to, eliminate the defects of human quality and improve the quality of the product.
Slitting machine operation guide ---
4 operational requirements
4.2.1 When loading paper, it is necessary to standardize the operation. If there are products that do not meet the quality requirements, the products should be picked out and clearly marked, and feedback should be sent to the squad leader.
4.2.2 Before the official production, the crew must pass the start-up information to each other, and it is not allowed to stack debris that interferes with the operation around the machine. The captain (blocking vehicle) shall compare the trial production sample with the standard proof, and self-check the product size specification. After confirming the pass, sign the first proof, and the sample will be retained until the end of the project.
4.2.3 When cutting, it is necessary to see the product specifications and determine in advance whether the size of the slitting knife meets the product quality requirements.
4.2.4 Each group of products must be self-tested, and the quality requirements and production process control shall be carried out according to the “Product Printing Process Card”.
4.2.5 After each group of products has been cut, the product label is affixed to the self-test and the production record is filled. The products to be re-rolled are processed on the shift; the items to be treated or scrapped are labeled and transferred to the treated area or waste as required. Area. The label of each product must clearly and accurately indicate the current product status, quality or problems.
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:
2. Automation control part: At present, the automation level of the slitting machine produced in China is still at the middle and lower level. Although the domestic control of the original device has been widely used and the price is lower, the domestic slitter manufacturers are far away in use. It lags behind the level of developed countries, especially in the control system, and the lack of organic combination with the structure of the slitting machine and the material to be cut. At this level, most of the domestic slitting machines still stay on the thick lines. The rigor and rationality of the cutting machine control system has not been fully understood. I personally think that the domestic slitting machine manufacturers should start from the above several directions, and find out the method that meets the cutting and cutting principle of the slitting machine and can maximize the use of the functions provided by the hardware.
