Bopp Tape Slitter Rewinder Machine

Bopp Tape Slitter Rewinder Machine

Slitting machine starts production
1. The winding roller is pressed down, the counter is cleared, and the production is started;
2. During the operation process, check the winding status of each joint from time to time, and adjust the tension according to the tightness of the winding to make each volume
The material is wound up and the end face is flush and firm;
3. Always pay attention to product quality during machine operation.
4. The machine has no abnormal sound.
5. Whether the photoelectric tracking operation is normal.
6. When checking the next volume, pay attention to check the surface of the product for quality defects and stick the tape as required.

Slitting machine operating procedures -

Third, through the film:

5. Press “Release Brake” again until the indicator light flashes and the unwinder brakes.
6. Press and hold the “Pinch with chain” button, the film is pulled through the chain to the sipe roll, and the film is removed from the shackle on the chain.
7. Press “Device Jog”, the film moves along the machine running direction to the winding side 2, both sides are pulled out, release the button, and flatten the film.
8. The “cutting knife switch” is in the open position, and all the cutting cutters that need to be cut are marked.

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).
