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
4.1 Preparation before cutting:
4.1.1 Before the cutting, the paper sent from the warehouse or the semi-finished products transferred from the previous process should be checked with the “production work order” to see if the paper quality, quantity, specifications, etc. meet the requirements of the work order. If problems such as quantity or quality are found, they should be promptly submitted to the dispatcher or feedback to the squad leader. After confirmation, the logo will be clearly marked and returned to the warehouse or semi-finished product area, and the qualified products will be re-sorted for cutting. If the feedback is not received, it will be deemed as acceptance. If there are quality problems such as insufficient quantity at the end, the personnel will be responsible.
4.1.2 Lubricate the equipment according to the maintenance requirements of the machine and check whether the safety protection devices of the equipment are effective.
4.1.3 Carefully check the quality of the front and back of the paper, graphics, paper, etc., to avoid the material specifications, model or quality of the products that are put into production do not match the requirements of the cut products.
4.2.1 Carefully check the accuracy and sensitivity of the electronic scale and vernier caliper, confirm whether it meets the requirements for use, and report the abnormality in time to report with the squad leader.

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.
