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);

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

 

thirteen. Foreign matter such as dust and small flying insects in the film roll
In the slitting process of the film, the mother roll film needs to be unwrapped and then slit and wound, which creates conditions for the entry of foreign matter. Since many film products themselves need to be in direct contact with foods, medicines, etc., the hygiene requirements are very strict, and the film is not allowed to be attached with foreign objects such as mosquitoes. Once found, it causes major quality complaints and claims, directly causing the company's economic loss and product brand. Damaged and negatively affected, therefore, the environmental cleaning and purification work in the production workshop plays a very important role in ensuring the quality of the film.

Domestic cutting machine development status and outlets ---

three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:

3. Manufacturing: This is a common problem faced by China's manufacturing industry. Everyone knows that any mechanical equipment, besides being reasonable in design, requires precision in manufacturing, and Chinese manufacturing is lacking in this respect. The manufacturing process is also a weak link. In addition to some general-purpose machine tools, there are some special equipments for manufacturing slitting machines, such as dynamic balancing machines, water cutting machines, etc., due to the manufacturing precision requirements of the slitting machine. High, therefore, some equipment needs to use CNC machine tools to process parts, especially the need to popularize the machining center, so that the processing precision of the equipment that produces the slitting machine can be fundamentally guaranteed.
