1. Slitting and Rewinding Machine imports PLC integrated control is used in electrical control system, human-machine communication is carried out by touch screen. Set and display working parameters are according to the requirements from different products.
2. Vector frequency-converting is adopted for rewinding, roll diameter is automatically calculated by PLC to achieve automatic tension control.
3. Magnetic powder brake is adopted for unwinding, roll diameter is automatically calculated by PLC to achieve automatic tension control.
4. Shaft-less pneumatic system for unwinding section is used, it is convenience for material roll loading and unloading with high
efficiency, automatic edge correction for unwinding roll (hydraulic automatic lifting system is optional).
5. Double tensioning shafts are used for rewinding, straight knife is used for slitting, smooth for the surface, and there is air suck fan device for waste edge.
6. In the system, there are calculations of meter, roll diameter, calculations of meter automatic machine stop etc.
7. The system has perfect mechanic, electric and pneumatic design, also good safety protection.
8. There are many different models such as 1300,1500,1700mm available slitter rewinder.
In recent years, tipping paper has developed and innovated in function and use. The use of tipping paper by tobacco factories is not limited to simple packaging, but also pays more attention to decorativeness, and has higher requirements for the printing aesthetics of tipping paper.
At the same time, with the growing popularity of cigarettes in health and environmental protection, on the one hand, perforated tipping paper has developed rapidly, especially the perforationtipping paper has become more and more popular among tobacco factories, playing an important role in the tobacco industry's defocusing project. Character. On the other hand, the food hygiene requirements of tipping paper itself are increasingly being valued by cigarette factories.
Nowadays, tipping paper uses a large amount of chemicals, such as inks, pigments, and organic solvents, in the printing process. These materials are very harmful to human health. Since the tipping paper is in direct contact with the smoker, the printing ink and coating of the tipping paper must be non-toxic, meet food hygiene requirements, and have certain water resistance and moisture resistance.
At present, the main difficulty in the environmental protection work of tipping paper is the problem of ink yield. For example, in the past one or two years, the pearly tipping paper commonly used in domestic high-grade cigarettes has been welcomed by cigarette companies because of its elegant and soft decorative effect. However, the sampling inspection by the National Tobacco Standards Center showed that a large part of the pearlescent tipping paper contained excessive levels of harmful substances such as aluminum and arsenic. To this end, some packaging companies are actively seeking solutions.
As a leading international pharmaceutical and fine chemical company, Merck Co., Ltd., in line with the needs of domestic manufacturers, not only provides relevant professional consultations to cigarette companies, but also introduces a new generation of pearlescent pigments, which not only maintains green and healthy health indicators, but also facilitates The preparation of pearlescent ink, the printing of tipping paper and the performance of a stronger gloss effect. In addition, such as Minfeng Shui Loong Paper Co., Ltd. insists on the use of self-produced traditional inks in the production of tipping paper, which not only reduces the influence of ink odor on the aroma of tobacco, but also reduces the amount of benzene contained in the ink, effectively ensuring environmental protection of the product. Sex. In general, health and environmental protection will be the future development trend and basic requirements of tipping paper.
