Advantages And Characteristics Of Rewinder

Advantages and characteristics of rewinder
The rewinder is a specialized equipment used for mica tape and thin film, and the rewinding process mainly completes three tasks:
Firstly, remove the rough edges of the original paper;
Secondly, divide the entire original paper into several widths that meet the user's specifications;
Thirdly, control the diameter of the finished paper roll to meet the factory specifications.
1、 Advantages of rewinder
1. Equipped with processing centerless, solid, roll tube toilet paper, it can instantly switch between products.
2. Automatic edge trimming, adhesive spraying, sealing, and shaft extraction are completed synchronously in an instant, ensuring no paper loss when the paper rolls into the band saw for cutting and packaging.
3. Pneumatic belt feeding, rewinding shaft and each shaft of raw paper have independent tension adjustment mechanisms.
2、 Characteristics of the rewinder
Compact structure and convenient operation
Receiving platform, prepared for cutting groove
Winding, unwinding, and traction all adopt variable frequency drive technology
PLC programmable controller as the core processing unit
Touch screen as a human-machine dialogue interface
High precision tension control
Automatic attenuation tension taper control
Fixed length deceleration
Fixed length parking
Forward and reverse functions
Static elimination function
3、 Maintenance of the rewinder
The transmission device of the toilet paper rewinder, such as the gear chain, needs to be greased after a period of time.
2. The rewinder generally does not have any problems, and 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 being used for one and a half years. It needs to be transported back to the factory for repair. In terms of the steel roller embossing device, if the embossing pattern needs to be replaced, the steel roller needs to be transported back to the original factory for modification.
3: Pay attention to the stable voltage of the rewinder, otherwise it may easily burn the motor; Pay attention to hygiene and avoid debris falling between the steel roller and the rough roller.
Use of slitting and rewinding machines
Self adhesive materials - Self adhesive label rewinding is a method of receiving materials after printing and processing of roll materials, and the labels after rewinding may be finished or semi-finished products. In the following situations, the self-adhesive material needs to be rewinded after printing processing.
a. Rewinding of finished product labels after printing and processing. Automatically label machines, printers, and electronic scales directly use the label after rewinding.
b. Rewinding of semi-finished product labels. The label needs to be reprinted or processed, and then reprocessed on a labeling or processing machine.

There are two rewinding methods on the label machine:
① Intermittent rewinding. Intermittent rewinding is applied to flat and circular label machines for intermittent paper feeding. The principle of rewinding is that when the material of the printing processing drum reaches a certain length, the sensor sends a signal to rotate the paper receiving roller and start rewinding. When the reel material shrinks for a short time after rewinding, the sensor sends a signal to stop rewinding, and the paper receiving roller is stationary. Complete the rewinding over and over again. The disadvantage of intermittent rewinding is that there is no tension during rewinding and the paper roll is loose. The paper roll that requires tight and uniform tension needs to be rewound again on the rewinder. If secondary processing of labels on rotating equipment is required, the intermittent rewinding device is an independent accessory form machine.
② Continuous rewinding. On the rewinding device of the rotary label machine.

Due to the synchronous process of rewinding with other processes, some rewinding devices are also equipped with tension control systems, so the rewinding drum is very tight. When reprocessing on the processing machine, the processing accuracy will not be affected by the paper's tightness.
c. Rewinding on the slitting machine. At present, many reel labels are printed and processed in large rolls on label machines, and finally rolled into large rolls. Then, the large roll label is processed and rewinded again on the slitting machine.
There are two purposes for copying on the slitting machine: one is to divide multiple labels into a single label, and the other is to copy a single label into a certain size and quantity of small labels, providing convenience for the application of labels in related equipment such as automatic labeling machines, barcode printers, electronic scales, etc.
