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

ten. Color circle

The factors that cause the film to roll the color circle are:
(1) Contamination equipment is contaminated: due to the pollution of the dust in the cutting workshop, as well as the operation of the equipment in the slitting process and the friction between the membrane and the friction generated by the static electricity, the cutting equipment continuously accumulates more and more dust. When it accumulates to a certain extent and fails to clean in time, it will pollute the slit film roll to form a color circle. In addition, the aging and hardening of the roll skin (sand) debris will also cause the color circle of the film roll to appear.
(2) The environment of the cutting environment is polluted: during the cutting process, due to the influence of some accidental pollution sources, such as the dust on the ceiling of the cutting machine, the exhaust of the diesel forklift, etc., the air is spread to pollute the cutting products. And form a color circle.
In order to effectively reduce the impact of color circles on product quality, the following measures must be taken:
(1) Do 5S work regularly to maintain the sanitation of the workshop and the cleanliness of the machine; (2) It is forbidden to open the doors and windows without sand filter for a long time, and keep the good habit of closing the door;
(3) The contaminated film on the surface of the parent roll must be removed before the film can be cut, so as to avoid the dirt of the surface film from contaminating the cutting machine;
(4) The diesel forklift that requires black smoke is kept away from the surrounding of the workshop to prevent the tail gas pollution from being cut into the products.

2. Lack of composite professional talents who understand manufacturing technology and process and know cutting process
In the manufacturing process of the slitting machine, different customers are often faced with different materials and requirements. If different manufacturers produce the same materials, the raw materials used are not the same chemical plant products, and the physical properties of the materials produced are not the same. When producing the slitting machine, it cannot be generalized. In the production process, the manufacturing process will change, especially in the size of the roll diameter and the thickness of the coating layer, the difference between the active roller and the passive roller and the wrap angle of the roller surface, etc. The lack of corresponding research talents in the field often leads to many waste products and defective products in the slitting process. Such composite talents should not only be familiar with the design and manufacturing process of the entire slitting machine, but also understand the different characteristics of different materials during slitting. Currently, it is very scarce in China, which leads to the current situation of domestic slitting machines.

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.
