Slitting machine operating procedures -

Third, through the film:

13. 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)

Reasons, countermeasures and effects of BOPP film slitting quality ---

 

thirteen. Foreign matter such as dust and small flying insects in the film roll

In addition, paper-end paper dust contamination, contamination of the film roll by the operator and the packaging staff, uneven size of the paper tube, label identification (length, weight, etc.), bumps, poor packaging, etc. are also easy to cut. For quality problems, we must pay attention to every detail during the operation and packaging process. For example, before the slitting machine starts, the film should be neatly placed and attached to the paper tube. The film should not exceed the end of the paper tube. Pay attention to the hands of the operator. Neat and clean environment of the cutting place, the packaging and handling process should be handled with care. When the film roll is moved down the manual forklift, pay attention to the stability, do not hit the film surface, the sealing box of the packaging process, the sticker cap, the sticker The labeling and labeling should be carried out in strict accordance with the specified requirements, position and size. It is not free to ensure the quality of the film products from every link.

2. Attenuation and tension compensation of the tension of the rewinding and unwinding: It is generally believed that maintaining the constant tension of the aluminum foil during the rewinding and unwinding of the aluminum foil is beneficial to the apparent quality of the finished aluminum foil, but it is not. The best method is to increase the tension of the aluminum foil according to a certain rule as the diameter of the coil increases, and the smaller the diameter, the lower the tension value. There are automatic tension control and manual tension control during the slitting operation. The automatic tension control system is the leading set tension attenuation value, which is maintained throughout the winding process. The manual tension control requires the operator to continuously adjust the diameter of the master roll to meet the tension required for the aluminum foil during operation. When setting the automatic tension operation, set the initial tension before setting the tension attenuation value. Taking the setting of the slitting and unwinding attenuation value as an example, the setting principle is that the aluminum foil tension attenuation value (%) is equal to the tension at the end of winding of the aluminum foil minus the initial tension and then divided by the initial tension. Multiply by 100%. When setting the automatic tension value of the unwinding, it should not be too large, otherwise the aluminum foil winding surface has a large hardness and is prone to warping. But the tension should not be too small, too small and easy to cause the rewinding body to be too loose, and the winding is not neatly running. Therefore, the quality of the rewinding and unwinding during the aluminum foil slitting operation is mainly affected by the change of the tension of the aluminum foil. It can be seen that the mastery of the retracting and unwinding control system is the key to affecting the quality.

3. The change of speed during slitting affects the change of tension: When the speed is increased or decelerated, the speed of the main motor changes. Firstly, it causes the instantaneous change of the tension of the unwinding traction to the winding section of the aluminum foil, and it is necessary to slightly vibrate the aluminum foil after a period of time to gradually stabilize the tension. The instability of this tension is manifested in the fact that the finished roll is not well-wound, and the end face has unevenness, which affects the quality of the product.
