Slitting machine operating procedures -
Third, through the film：
1. The cutter exits to the stop position. (The split knife switch is in the off position)
2. Press the “Pinch with chain” button and the hook and loop on the chain will run to the feeding position.
3. Press “Release Brake” until the indicator light is on, and the unwinder brake is released.
4. Pull one end of the film manually, pull the film along the running route to the film-piercing mechanism, and fix the film to the shackle of the chain.
Reasons, countermeasures and effects of BOPP film slitting quality ---
twelve. Interface quality problem (poor interface quality, interface identifier does not match)
2. Interface identifier
Due to the large thickness of the film interface, the film roll for some applications must be properly handled at the interface to avoid unnecessary problems, such as slowing down, increasing the gap between the coating blade, and printing the offset plate. The interface products must be identified as necessary to facilitate customer identification and internal management.
1 The color of the adhesive interface is generally beige, special requirements are used according to the regulations. For example, Shanghai Ziquan requires the use of black adhesive tape; the marking method of the joint position is operated according to the regulations, such as Zhuhai Zhongfu Pearl Film, Shenzhen Ruimei The hot film is required to be marked at the ends of the interface with yellow paper dust protruding from the end of the film roll by about 1 cm; other special marks are operated according to the requirements of the production tribe.
2 Require the slitting workshop to mark the length number of the joint product without special requirements after the length of the label in the length column of the package label, and mark the “buter” mark on the note bar of the computer, and mark “+” on the remark column. Marking, pearl film and imitation paper film and exporting pearl film should indicate the length of each product before and after the joint on the length column of the product specification. For special requirements, the relevant marking work should be done according to the regulations (such as Shanghai Ziquan product port). The rate of less than or greater than 25% requires the number of interface products on each board product).

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.
