Bopp Jumbo Tape Slitting Rewinding Machine

Bopp Jumbo Tape Slitting Rewinding Machine

Tape slitting machine feeding, filming and filming
1. Loading: According to the requirements of the cutting plan, according to the driving operation rules, according to the actual situation, hoist the corresponding mother roll on the aging frame, place it on the unwinding unwinding frame according to the inner and outer selection direction of the corona surface, and use the control button Clamp the steel core, leave the steel core support arm and drive.
2. Film penetration: When there is no film on the slitter, the film must be penetrated. Using the slitting machine through the membrane device and the function keys, one end of the original membrane is attached to the membrane chain eyelet, and the membrane button is activated to distribute the membrane along the slitting process to be evenly distributed on each roller.
3. Film: When there is a film on the slitter, when changing the joint, use the vacuum filming table to start the filming station to the working position, manually flatten the film on the first pulling roller of the slitting machine and start the upper vacuum pumping film. Soak the film flat on the filming table, attach the double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding frame and start the lower vacuum pump to make the film flat and absorb the paper. Layer and flatten the adhesive film, the joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps to open the filming station to the inoperative position.

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

(3) Causes of loose/overtightening of the film roll
1. The influence of the cutting parameters (winding sheet / pressure curve setting factors, etc.);
2. Effect of film properties (stiffness, thickness, single/double corona surface, smoothness, static electricity, etc.)
Ringing, the slitting parameters must be set according to the film with different characteristics);
3. The effect of the winding speed (when the winding speed is slower, the more time the slitting process is to discharge the air in the film roll, the tighter the film winding is);
4. Product specifications (width, length, collocation, etc.);
5. The influence of the performance of the slitting equipment (adjustability, stability, operability, etc.);
6. The influence of operational factors (professional level, operational skills, job responsibility, etc., generally expressed in the insertion
7. The quality of the work is wrong, such as poor air-suction, rewinding card head position, poor adjustment, and unwinding roller pressure; The influence of environmental factors (temperature, humidity, etc.);
8. Influencing factors of the appraisal system (Operator considers the appraisal of the secondary processing and rewinding indicators in the workshop, and often adopts the coping method of winding up and not loosening, which is one of the factors that cause the film roll to be over-tightened);

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).
