Opp Packaging Tape Slitter Rewinder

Introduction to slitting machine:
     Slitting machine is a kind of mechanical equipment for slitting wide sheets of paper or film into a plurality of narrow-width materials, which are commonly used in papermaking machinery and printing and packaging machinery.
     The traditional control scheme of the slitter is to use a large motor to drive the shaft of the rewinding and unwinding. A magnetic powder clutch is added to the reel and reel, and the resistance generated by the magnetic clutch is controlled to control the tension of the surface of the material. . Magnetic powder clutches and brakes are special automatic actuators that transmit torque through the magnetic powder filled in the working gap. The magnetic current can be changed to change the magnetic state of the magnetic powder, and then the transmitted torque can be adjusted. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high speed section fine adjustment and medium and small power speed control system. It is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension control system with a constant tension during winding.

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.

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).
