Slitting machine operating procedures -

Second, the volume of the replacement of the finished product (operating station)

8. Operate the button on the winding arm to wind up the paper core.
9. Manually cut the film to be cut onto the corresponding rewinding paper core. After tightening the film, it is firmly adhered to the paper core (note that the side 1 and side 2 films are differently worn).
10. After all the paper cores on both sides are glued, press “Crop 1 Clamp” and “Reel 2 Clamp” at the same time, and then press “Rewind side 1 open” and “winding side 2 open” at the same time. The position is automatically swung until the winding paper core is pressed against the upper roller, the winding main body is started, and the film is slowly wound until it is tight. (The two-button white indicator light turns from blinking to steady light)
11. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.

12. The main operator shall check the winding condition of each film and fine-tune the winding arm if necessary.

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.

three. Irregular end faces

2. The effect of uneven end faces on usage
Regardless of the type and purpose of the film, the problem of "alignment" is involved, and the user generally uses the form of electric eye tracking to perform alignment. The film roll with irregular end faces, the wrong film layer appears to be bent under the pressure of the package, and the electric eye is difficult to track during use, which affects the use effect, such as inaccurate printing overprinting, misalignment of the bag, and the like. In addition, the film roll with irregular end faces is inconspicuous, and the "selling phase" is poor, which affects the brand image of the product.
