Tape cutting machine receipt:
1. When the inner and outer ends of the machine are stopped, use the unloading button to place the film on the prepared unloading trolley, cut the film and paste the film roll with the sealing glue.
2. Use the collet release button to release the chuck and check whether the film cores have left the core. If one is still stuck on the core, manually remove the film roll manually.
3. After ensuring that all the film leaves the chuck on the trolley, use the film button to raise the winding arm, install the corresponding paper core, and attach the film to the paper core for the next slitting.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

(iv) Effect of film roll tightness on product quality
1. The winding is too tight:
1 fluttering/starting bone: As BOPP film, it is normal for the thickness of the product to fluctuate within a reasonable range. If the reeling tightness is appropriate, this thickness fluctuation will not affect the quality of use, but when the slitting is too tight The thicker layers of the film are stacked together to cause edge thickness or bone swelling, which affects the quality of use. The fluttering or bone formation that is formed by over-tightening is often difficult to find during the slitting process, but after the product has been stored for a period of time, the problem will be highlighted. In addition, there are several types of products with uneven thickness defects that can be easily revealed, such as ultra-transparent tape film, crystal film, heat sealing film, etc., while fluttering and bone-starting phenomenon will cause different quality of all film products. The degree of influence, especially for products that require printing and processing, is particularly prominent.
2 Adhesion: over-tightening of double-sided corona products, anti-corona products and products with less anti-adhesive content will cause adhesion quality problems, and the problem can only be found in the customer's use, the impact is great, and appears Products with adhesion problems can only be disposed of as scrapping, causing large losses to the company.
3 Face wrinkles: Due to the tight winding, the film cushioning performance is degraded. The wrinkles formed by the extrusion of the film on the end face of the product during handling and loading and unloading are difficult to eliminate, forming the end wrinkles and affecting the quality of the product.
4 Pitting: Due to the tightness of the winding, the film near the paper tube is affected by the rough surface of the paper tube, which causes pitting, which affects the quality of the product. The use of the polished paper tube will eliminate the surface of the film and improve it. Start wrinkles).

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

Seven. Sharp edge
The curling occurs at the edge of the film winding, which causes the curling. The reason is that the edge of the thick film is curled up and the edge part is lifted up; the second is that the winding is too tight, and the tension can be shortened by slitting. Speed ??to improve the resulting edge curling phenomenon; third, the cutter is too blunt, and the stretching phenomenon occurs at the slit when slitting, causing the edge of the film roll to be turned outwards after winding to cause the curling edge, and the cutting should be replaced in time. The knife can avoid the occurrence of the curling problem; the fourth is that the tool is not installed correctly, such as the blade is close to the edge of the sipe and the blade is passivated. Cutting with a round knife can improve the curling of the film roll.
In the use of the unwinding process, there will be different degrees of side-floating in the unwinding process, and it is impossible to track the alignment with the electric eye, which directly affects the use effect. Therefore, it is necessary to change the product with the curled edge.
