Bopp Stationery Tape Slitting Rewinding Machine

Bopp Stationery Tape Slitting Rewinding Machine

Slitting machine operating procedures -

Third, through the film:

5. Press “Release Brake” again until the indicator light flashes and the unwinder brakes.
6. Press and hold the “Pinch with chain” button, the film is pulled through the chain to the sipe roll, and the film is removed from the shackle on the chain.
7. Press “Device Jog”, the film moves along the machine running direction to the winding side 2, both sides are pulled out, release the button, and flatten the film.
8. The “cutting knife switch” is in the open position, and all the cutting cutters that need to be cut are marked.

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).

Slitting machine parts ---

1. Type of inspection system for the tension and speed of the slitting machine:
1 Tension sensor detection: The tension sensor is installed under the bearing of the tension detecting roller, converts the detected aluminum foil tension into an electrical signal, sends it to the tension adjuster, compares it with the original set tension signal, performs PID calculation, and then inputs The winding motor controller achieves the purpose of controlling the tension and rotation speed of the winding roller.
2Floating roller indirect tension detecting system: a set of floating roller is installed in front of the aluminum foil tracking roller. The position of the floating roller is detected by a potentiometer. The tension control method is to keep the tension constant by keeping the position of the floating roller as constant as possible. .
3 The magnetic powder clutch is used to control the rotational torque of the input winding roller to achieve tension control: the magnetic powder clutch is composed of an active part and a driven part, and is connected to the winding roller through a transmission mechanism such as a universal joint, and the fine ferromagnetic powder is filled in the middle. As a torque transmission medium. A magnetic field is formed by applying a constant current to the exciting coil, and the magnetic powder is magnetized. The magnetized magnetic powder attracts each other to form a chain arrangement. When the active part rotates at a constant speed, the coupling force between the magnetic powders is broken to form a circumferential tangential force, and the product of the tangential force and the radius of the magnetic ring is the driving driven part. The winding torque of the winding realizes the coupling of the output torque from the active part to the driven part in continuous rotation, thereby achieving the purpose of controlling the tension.
4 slitting Unwinding capacity and speed detection system: The magnetic powder tension brake is mainly used to control the unwinding force and speed. The working principle is: the coupling is installed in the magnetic powder brake, and the input parts and output with magnetic coils are installed. component. Below the magnetic coil is an annular groove, the underside of which is an annular rotor or output member. The annular groove is located at the center of the output member and is filled with magnetic powder. When there is excitation current in the magnetic coil, the coil generates magnetic flux to align the magnetic powder in the direction of the magnetic field, thus generating damping between the input member and the output member, and transmitting the torque. If the tension and speed applied to the aluminum foil are increased or decreased, the magnitude of the exciting current can be changed, or the magnitude of the current applied to the coupling coil by the varying amplifier can be effectively controlled.
