Plastic film slitting process and precautions
Apr 10, 2019
The slitting of plastic film is a very common process. When preparing for start-up, firstly, the appearance of the plastic film of the previous process, printing and compounding is tested, and the hardness and appearance flatness of the plastic film are tested to see if the cutting can be achieved. Requirements. Then, fully understand the performance of the slitting equipment that is about to run, and check the main operating parts and electrical control parts of the equipment.
At this time, the plastic film is good, the blade is adjusted according to the specifications required by the user, and the production is started according to the normal production process. The normal operation of the slitter is the basis for ensuring the quality of production. When entering normal production, the speed of the slitter should be strictly in accordance with the process requirements. By controlling the cutting speed, you can get the quality you need for slitting.
According to the performance of the equipment and the intrinsic properties of the plastic film and the different specifications of the film, the appropriate slitting process is used for production. Because the process parameters, identification methods, and values of various slit films are different, the process should be carefully adjusted for each product. In the production, the frequency of each station of the slitting machine is different, so the degree of wear is also different. Therefore, there will be differences in performance.
Therefore, each operator should pay attention to the correct selection of the work station, play the good condition of the equipment, grasp the use of the site, continuously summarize the experience, and find the use of the good characteristics of the equipment. In addition, it should be noted that in the process of slitting, each film is re-opened and re-rolled, which creates conditions for foreign matter to enter, and the plastic film product itself is mainly used for food and drug packaging. Therefore, the hygiene requirements are very strict, so it is necessary to ensure the cleanliness of each film.
