Tape Carton Sealing Jumbo Roll Cuting Machine

Inspection and preparation before the cutting machine is turned on
4.1.1. Confirm that the main power supply voltage is 380V.
4.1.2. Turn on each power switch and check if the electricity and gas supply are normal.
4.1.3. Before starting the machine, you must confirm that the surface of each guide roller is smooth and free of burr dust, debris, etc. When cleaning the machine, use alcohol or water to soft cloth.
Wipe, can not be wiped with other solvents, remove the impurities around the equipment and production, to ensure normal production;
4.1.4. Obtain all kinds of accessories and tools such as slitting products and tapes in strict accordance with the production instruction sheet and the process card requirements.
4.1.4.1. Receive the composite film specified on the production instruction sheet, check whether the composite film tracking card is complete, and describe the previous quality problem is it clear.
4.1.4.2. Confirm the cut specifications, roll direction, batch number, material structure, winding diameter or meter number according to the production order. 4.1.5. Carefully check the equipment to confirm that each rewinding mechanism, EPC device, and tension control system are normal, and confirm static electricity.
Whether the elimination is normal or not;
4.1.6. The unwinding material is ready, and then the film is routed in the correct way;
4.1.7. Prepare the winding paper core according to the slitting specifications and place it in the corresponding position of the winding reel.

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

(iv) Effect of film roll tightness on product quality

(5) Coping methods
1. Reasonable principle: Applicable is reasonable, which means that the cutting operator and the quality inspector are too loose according to the winding/
Too tightly influence the degree of influence on different products, adjust the cutting process reasonably, and reasonably grasp the tightness of the film roll to meet the requirements of the use of film products.
2. Ningsong Motight principle: objective when cutting equipment status, product specifications, film performance characteristics, etc.
When the influence of the condition causes the winding tightness to be in an inappropriate degree, the principle of tightness is generally used, because the problem of over-tightening often makes the film unusable, except for the special requirements.
3. The principle of primary and secondary: it means that in the process of slitting production, small groups should be followed to the interests of large collectives.
The principle of benefiting the interests of the company, avoiding the pursuit of high output and high distribution for the purpose of reducing the quality of cutting, all should be based on product quality, maintaining the German crown film brand as the responsibility, effectively completing various production and quality indicators Effectively serve the enterprise and users, and strive to be the best supplier of film.
4. System Management Principles: Refers to the use of systematic, scientific management methods, practical, theoretical, and empirical
The accumulated cutting control method is compiled, and according to the optimal combination of different types of products, width, winding length, season and other external variables and slitting tension, pressure and other internal variables, the document control management is performed to form an operation guidance document. Minimize the influence of subjective factors, reduce the impact caused by insufficient individual ability or excessive dependence on experience, and continuously supplement, optimize and improve the operation guidance documents to meet the needs of system management.

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