The rewinder is a special equipment for papermaking. Its purpose is to rewind the paper rolls (called base paper rolls) produced by the paper machine in turn. After the paper is rewound, the finished paper is made into the factory. At present, it has become a development trend in the papermaking machinery industry to use AC drive instead of DC drive for rewinders. The paper roll rolled by the reeling machine is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, and the width of the paper cannot be directly used in paper processing or printing machines. Most paper types (such as newsprint) , letterpress printing paper, wrapping paper, etc.) must be trimmed, slit, spliced by a rewinder, and re-rolled on the core of the paper roll to form a finished paper roll of a certain specification and a certain tightness before leaving the factory. The rewinding process mainly completes three tasks: firstly, cutting off the raw edges of the base paper; secondly, cutting the whole base paper into several widths that meet the user's specifications; thirdly, controlling the roll diameter of the finished paper roll to make it meet the factory specifications .
First, the advantages and characteristics of the rewinder:
Rewinder, toilet paper production equipment. It can be divided into automatic toilet paper rewinder and semi-automatic toilet paper rewinder.
The automatic toilet paper rewinding machine adopts PLC computer programming technology, man-machine interface operation, automatic glue spraying, frequency conversion speed regulation, edge sealing and edge trimming at one time.
1. Equipped with processing centerless, solid, and roll paper toilet paper, which can instantly switch between products.
2. Automatic trimming, gluing, sealing, and shaft pulling are completed in an instant, so that there is no paper loss when the roll paper is transferred to the band saw for cutting and packaging.
3. Pneumatic belt feeding, rewinding shaft and each base paper have independent tension adjustment mechanism.
¤ Compact structure, easy to operate
¤ Material receiving platform, equipped with cutting groove
¤ Rewinding, unwinding and traction all adopt variable frequency drive technology
¤ PLC programmable controller as the core processing unit
¤ Touch screen as man-machine dialogue interface
¤ High precision tension control
¤ Automatic attenuation tension taper control
¤ Fixed length deceleration
¤ Fixed-length parking
¤ Forward and reverse function
¤ Static elimination function
2. How to maintain the rewinder?
1. The transmission device of the toilet paper rewinder, such as the gear chain, needs to be buttered over time.
2. There is generally no problem with the rewinder. The consumable parts are nothing more than small gears. If one is added, the printing knife is easy to break, and the wool roller will become thinner after a year and a half of use. It needs to be shipped back to the factory for repair. In terms of the steel roll embossing device, if the embossing pattern needs to be replaced, the steel roll needs to be transported back to the original factory for modification, which does not cost much.
3. Pay attention to the stable voltage of the rewinding machine, otherwise it is easy to burn the motor; pay attention to hygiene, do not let the sundries fall between the steel roll and the wool roll.
