Why Two Drum Center Surface Slitter Rewinder?
Are you looking to cut paper, plastic, or film? You’ve come to the correct place. We have a large selection of slitting machines that can do the job.
The slitting machine is used to cut any shape into several strips, such as kraft paper, water-activated tape, coated paper, and other thick materials.
It is useful in the paper converting industry, where it has become an essential component of binding machinery for making small rolls.
Jota Machinery manufactures one set of two drum center surface slitter rewinder that work to transform a mother jumbo roll into a son small roll. The maximum rewinding speed is 500-600m/min.
The slitter rewinder was manufactured about a year ago, and it has been supplied to Russian consumers. They primarily manufacture kraft paper.
Kraft paper is used in a variety of industrial uses, including bags, wrapping, building materials, and even as a newspaper.
It is formed of paper pulp and is noted for having a strong and stiff structure. It has high tear resistance, making it ideal for the job that it serves.
Aside from its strength, kraft paper offers good water resistance and can only absorb water to a certain extent.
This makes it ideal for usage in pharmaceutical companies, where even minor contamination can have serious consequences on products as diverse as cosmetics.
The center surface rewinding is a new slitting technique that is based on the standard slitter rewinder. When the material is largely thin and soft, it can be used.
Unlike other Jota Machinery slitting machines, this one is designed to cut mother jumbo rolls into son jumbo rolls.
Hydraulic shaftless unwinder stand
Some mother jumbo rolls are oversized in paper mills, they are super hefty jumbo rolls and the weighing more than a ton.
Hydraulic shaftless unwinding is a novel form of unwinding technique in which the air shaft is not manually threaded into the parent roll.
The unwind stand has a chunk at the front and back ends.
To use the hydraulic station to raise and lower the parent roll, just line the chunk with the paper tube of the parent roll and then operate the remote control.
As I previously stated, this slitting machine is appropriate for large parent rolls. Our greatest unwinding diameter is 1500mm.
Slitting blade using pneumatic action
Pneumatic slitting blades are commonly used in the textile, printing, and packaging sectors for cardboard, paper, textiles, fabric, and other non-ferrous materials.
The speed can be automatically adjusted by the electronic control based on the thickness of the material. The service life can be extended up to 500,000 times.
Lower circular knife devices, upper circular knife devices, and so on comprise the entire set of slitting units.
A knife shaft, a circular knife, a bearing seat, and a servo motor comprise the bottom circular knife device.
This slitter machine is outfitted with 20 lower round knives, each having an outer diameter of 200 and a servo motor driving the round knives’ shaft.
The upper round knife device is made up of a beam, a knife seat, a round knife, and so on, and this machine has 5 upper round knives.
Loosen the nut to move laterally when altering the location of the upper circular knife.
To modify the amount of bite, loosen the square nut and move the upper round knife left and right. Tighten the nut after adjustment.
The upper round knife has a diameter of 150. The air cylinder controls its lifting and lowering operations.
Simply turn the air valve on the control box panel to the “up” or “down” position to control the slitting and feeding.
The upper round knife beam is a dovetail groove construction that holds the upper round knife in place. It is mounted to the rack’s wall plate, with adjustment devices on both sides.
Before and after the bottom circular knife, there is a 200mm paper support roller to keep the paper web on the same plane. Idler rollers are used to support the sheet and keep it at a consistent angle when it enters the slitter.
Unloading of the paper table
A paper unloading table, an oil cylinder, and a bearing seat comprise the paper unloading table apparatus.
The tabletop of the paper unloading table is a welded section of steel construction.
After the finished paper roll is completed, the operational platform “lifts” the paper unloading table, and the paper roll is pushed onto the paper unloading table by the paper-pushing device.
To unload the paper roll gently, press the “down” button on the console; the unloading speed is controlled by the throttle valve.
The electrical operating table can be used to control the “up” and “down” movement of the paper receiving table.
Jota Machinery is dedicated to supplying paper mills with paper conversion services.
