Working principle of slitting rewinder

- Jun 05, 2019-

1. The slitting and rewinding machine must slice the whole roll or the whole raw material with fixed length, such as plastic packaging materials, packaging cartons, steel plates, film, leather, wood chips and so on. It must use fixed length slitting control.

2. The cutting length can be set continuously. If the actual cutting length has errors, it is easy to calibrate by setting parameters.

3. Slitting control of slitting rewinding machine is divided into static and dynamic slitting: accurate shutdown when the set length arrives, then static slitting processing, restart operation after slitting; when the set length arrives, non-stop slitting signal is sent out, and dynamic slitting processing is carried out in the course of material movement.


Structural advantages of slitting rewinder:

In the middle of the slitting rewinder, there is a spindle for processing paper tube. The front end of the spindle is fixed on the base with a group of bearings, and a belt pulley is installed in the middle of a group of bearings. A compressed cylinder is installed near the base, and a set of support rod bearings is installed at the upper end of the support rod of the cylinder to support the spindle.


The upper end of the slitting rewinder is equipped with a main knife shaft, on which a number of blades are arranged according to a certain gap, and the support bracket of the main knife shaft is also provided at the top of the slitting rewinder, and the supporting cylinder is installed in the middle of the support bracket.


The structural advantage of slitting rewinder fills the technical gap of fully automatic pipe cutting machine.
