Second, the use of procedures;
1. Check whether the parts of the machine are loose due to transportation and other reasons, adjust the four foot screws of the machine, and verify that the machine is level on the ground.
2. External high-pressure gas is supplied to the pressure regulating valve. The purpose of the second air pipe blowing is to eliminate the residual nozzle in the empty groove at the lower right of the drum, so that the drum can smoothly accept the new nozzle and adjust the pressure of the pressure regulating valve. The best use.

Reasons, countermeasures and effects of BOPP film slitting quality ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)

 

(2) Causes and countermeasures of longitudinal wrinkles
Longitudinal wrinkles mean that the surface of the film roll forms a circumferential rib line. In the process of slitting, a large amount of air entrapment or cumulative thickness unevenness is the main cause of longitudinal streaks, and it is difficult to eliminate the occurrence of a relatively serious stripe. When the longitudinal wrinkles appear in the slitting process, the tension is reduced and the pressure is applied to discharge the air in the film roll to improve the longitudinal wrinkle problem. However, the adjustment range should consider the impact on wrinkles and other aspects (according to relevant professional information, longitudinal wrinkles One of the reasons is that the slitting speed is too fast, and the film roll is most prone to the quality problem of the longitudinal stripe at high speed, but there is no obvious influence in actual production, which remains to be studied). Another reason for the vertical wrinkles is the influence of the running accuracy of the equipment. For equipment with high requirements for running accuracy, after a long period of continuous use, the running accuracy of some components has decreased. For large slitting machines, it is more difficult to ensure the running accuracy due to the large number of running parts. Moreover, since the plastic film is a polymer product, its thickness is very thin, and it is more susceptible to damage during processing. Therefore, once the running accuracy is insufficient, quality problems such as vertical streaks are likely to occur. For this reason, it should be cautious when replacing equipment parts and accessories. It is advisable to use durable and high-precision parts, and it must also ensure a certain precision during installation. Otherwise, it is difficult to meet the operation requirements of the slitting machine.
The flattening roller flattens the film and eliminates some of the longitudinal wrinkles produced by the film under tensile stress.
(3) Causes and countermeasures of cross wrinkles
In addition to the influence of the parent-rolling factor, the transverse wrinkles of the film are mainly caused by the sag-like transverse wrinkles produced by the loosening of the slit film roll. Generally, the slitting process is effective in reducing the wrinkles and reducing the pressure, and should be effective for different types of products. Adjusting the slitting and pressure can effectively eliminate the occurrence of cross wrinkles.

six. Burr

The raw edge product not only affects the appearance, but also directly affects the use. The edging product is observed with a magnifying glass. The edge of the film is jagged. The film roll is prone to breakage during use, and the consequences are very serious. For example, if the printed film breaks during the printing process, the ink will be caused. Splash, need to clean the machine and the ground, and then lead the film, re-coloring and other processes, production of physical and working loss; if the tape film breaks during the coating process, it is necessary to open the oven more than ten meters, re-introduction Membrane, turn off the oven, heat up and reproduce. These are things that users are very annoying and we must pay attention to.

In addition, we must pay attention to the protection of the end face during the moving process of the film roll, the film end face gap caused by the operation accident, and the gap has high concealment, the problem is difficult to find and flow to the user, the product will be Use has a greater impact.
