Want to make sure the stability of the composite film cutting quality, these points must be put down!

For cutting the working procedure, must be addressed, not taken lightly. Combining with the composite BOPP/LDPE composite film, when cutting and production technology and quality problems of cutting machine of related issues, are analysed. In order to make the composite film production factory, cutting and production in the future can well solve the problem of a series of quality, to ensure the stability of the composite film cutting quality. 1, according to user requirements, the purpose of cutting provide accurate specifications. When 2, put in cutting volume, but on the whole process when composite extrusion composite large volumes of composite membrane for inspection again, to see if there were any quality problems. 3, can correct the wrong layer of the composite membrane or cutting off part of the printing and composite defects, improve the level of product rate. 4, can make the finished product achieve good winding state. Points to note 1, control the cutting speed in normal production, the speed of the cutting machine should be in strict accordance with the technical requirements. Too high will affect the cutting quality. Therefore, control the cutting speed, can get cutting and the required quality. Because in the process of production, some operators in order to increase production, improve their economic benefits, to artificially increase the cutting speed, this will make the film under high speed, prone to longitudinal stripes and wrong layer quality problems. 2, according to the equipment and film properties to choose the appropriate cutting process must be according to the equipment performance in the normal production and internal performance and different specifications of film film, adopting appropriate cutting process, for production. Because of various process parameters of thin film slitting and recognized method, the numerical value is different, must be careful adjustment process for each products. 3, pay attention to the correct choice in the production of workstation, cutting machine use frequency is different for each station, and the wear degree is also different. So, will show some differences in the performance. For status, for example, a better location cutting products, less vertical stripes. On the other hand, the longitudinal stripes even more. As a result, each operator must pay attention to the location of the right to choose, best play equipment, grasp the site usage, constantly sum up experience, find the device using the method of the best. 4, ensure good film clean on the other hand, it is also to note that both in the cutting process, every roll of film was reopened, rewinding, such foreign body into the created the conditions to the outside world, and the film the product itself is mainly used for packing food, medicine, so is very strict on health, so must ensure that each roll of film to clean. Production control points 1 slitting and cutting material consistent with process of single. 2, cutting of the coil emits the direction consistent with process of single. 3, cutting and cutter location are in conformity with the request or single template. 4, slitting width size is consistent with process requirements. 5, cutting volume end face flush, without buckling, critical phenomenon of reinforcement. 6, printing, composite quality ( Overprint, lack of printing, the tail cutter line, dirty, ink, foam ( Spot, grain) Dot, wrinkle, lack of glue line, smudgy class) Question total elimination. 7, cutting coil health, no oil pollution, the paper scraps, diaphragm and so on. 8, photoelectric detection object choice is correct, the photoelectric detection head induction high sensitivity, fast rectifying motor. 9, and winding tension setting appropriate, don't run up, stretching wrinkle around.
