Slitting machine instruction manual -
Second, the use of procedures;
4. Check the position of the knife holder and the nozzle of the drum on the left side of the drum, and adjust the left and right distance of the blade so that the blade can be cut into the blade groove of the drum in the middle. The distance between the two blades is the length of the cutting nozzle: 20mm and 15mm. , tighten the screws on the blade holder to secure the blade position
Reasons, countermeasures and effects of BOPP film slitting quality ---
twelve. Interface quality problem (poor interface quality, interface identifier does not match)
1. Interface requirements
Due to poor interface, the quality of the film roll may be broken or wrinkled, which may cause adverse effects in the user's use. Therefore, the film interface must be connected to the specified specification to ensure the joint quality of the interface. Specific requirements are as follows:
1 The two sections of the joint are cut and flattened horizontally, and the beige (or other specified color) adhesive tape with a width of 72 mm is firmly adhered to the front and back sides of the film;
2 In order to improve the interface quality, the film interface is required to be straight and balanced with the paper tube direction, and the interface is required to be flush and wavy. The interfaces at both ends are in the middle of the tape. Try to avoid the size of the edge. The adhesive tape is attached to the film. No obvious bubbles;
3 The film surface at the interface is required to be smooth without obvious wrinkling;
4 Do the identification of the joint position as specified.
Domestic cutting machine development status and outlets ---
1. Not rigorous in the manufacturing process
Tolerance control in the mechanical manufacturing process is not precise enough, and the surface is rough, especially in the matching electroplating industry, which is shoddy. There is a defect in the dynamic balance of the roller for cutting the Chinese-made equipment at one time. The lag of the related industry, the rubber coated by the roller has far less wear resistance and anti-aging than the foreign products. The bearings used seem to use well-known foreign brands, but the counterfeit and shoddy floods the domestic bearing market. Even when the real goods are purchased, the precision is far lower than the precision used by foreign slitting machines.
In the entire production process of a slitting machine, there is no guarantee of production process. At present, most of the slitting machines produced in China are completed by a number of outsourcing units, and the quality of their production is even more difficult to guarantee. In addition, the metal materials used and the heat treatment process are not rigorous enough, resulting in many problems in the use of a slitting machine. It has seriously affected the share of a slitting machine in the domestic market. The secondary and tertiary slitting machines have fewer problems than the one slitting machine, because the parts of the secondary and tertiary slitting machines are completed by the slitting machine manufacturer, and the dynamic balancing machine used is in a narrow range. It can accurately control the unbalanced grams, and the industrial difficulty coefficient of manufacturing is reduced. Its selling price is far lower than that of foreign products. Therefore, the proportion of domestically produced slitting machines in the domestic slitting machine market getting bigger.
