Heavy Duty Frame Type Paper Slitter Rewinder Developed By Jota Machinery

Last Update Time；11/10/2022

In the paper industry, you are constantly striving for higher, wider, and larger productivity.

You will have to wind or rewind heavy rolls with your machine at some point. As a result, we provide a tough heavy-duty paper rewinder that can handle most of your high-volume unwinding needs.

It is easy to put together, and its small size makes it portable—not only from one machine to another, but also from one location to another as needed.

A paper mill’s productivity is of the utmost importance.

Larger paper pulping and paper coating machines are typically used in pairs, necessitating the use of two heavy duty slitter rewinders.

When there is an extra rewinder available, you can streamline your workflow. As a bonus, more time is available for other maintenance tasks such as setting adjustments.

The heavy-duty paper slitter rewinder is the ideal solution for increasing your paper line’s productivity and throughput. High-quality, high-speed construction.

Jota Machinery would then introduce a new paper slitter rewinder in August 2022. This heavy-duty slitting machine is smaller, faster, and more efficient than our previous model.

It has a small footprint and a high cost-performance ratio. When compared to Jota’s previous model, the rewinder runs at a high speed of 1200m/min and saves 50% space. while the hydraulic station is built within it, making operations far more convenient than before

This heavy-duty, high-speed paper rewinder is designed for production lines with widths ranging from 2000 to 3800mm and a maximum rewinding diameter of 1800mm.

If you have a high demand for your wide web, this heavy-duty paper rewinder is ideal.

A machine with a width of up to 2800mm provides high capacity, increased productivity, and optimal performance even in harsh industrial environments. The new features enable you to fully utilize both the rewind system and drive technology.

When the process width is increased, the paper width and tension on the face paper are inevitably reduced.

Jota Machinery’s heavy-duty paper slitting machine, equipped with world-class rewinding technology, can perfectly solve this problem, and recover this loss. It has established itself as an industry leader, offering hydraulic or pneumatic tensioning cylinders as well as a large capacity brake system.

Our heavy duty paper slitter rewinder are built to last and are built to withstand harsh production environments. With a continuous conveyor speed of 1,200m/min, each rewinder has a large capacity and fast speed.

The Frame of The Slitter Rewinder.

The machine frame was designed and built by our dedicated team of engineers. We set up the machine frame with a 65mm thick steel board to ensure the machine’s stability and the precision of our products, and all the machine walls are well machined by the CNC machining center with high precision.

The machine frame, made of high-quality alloy steel, is specially designed to keep the rewinder from deforming after extended use.

Before each component is assembled, we ensure that it has been thoroughly processed and polished. Then we precisely assemble those parts into a single machine that can run indefinitely.

The machine frame is thick and sturdy, and the CNC machining center is highly accurate. The processing accuracy should be no more than 10micro to ensure the machine’s functional stability.

The total weight of the slitter rewinder machine is more than 12000kg. It ensures that your paper roll is converted properly on it.

Unwind Stand with Hydraulic Shaftless.

Do you know how much a 2800mm wide by 1800mm diameter paper roll weighs?

The answer is 3500-4000kgs. Yes, it is between 3.5 and 4 tons.

How does an unwind stand clamp such large, heavy paper rolls?

For you, our skilled engineer has upgraded a heavy plus type shaftless unwinder stand.

You can easily hang the heavy paper roll onto the balance shaft of a shaftless unwinder and begin working. All of this with no manual labor!

We’ve all seen what happens when an unwinding axis fails.
It could be due to lubricant shortages or clogged brushes.

That is why we designed the shaftless unwinder as a complete system to provide you with complete peace of mind.

We can handle it all, whether you need individual components or the entire package. This complete package includes a shaftless unwinder and an endless paper rewinding system.

The shaftless unwinder stand is an innovative and one-of-a-kind product. It has two hydraulic systems: one for clamping the paper rolls with the chuck and one for lifting the paper rolls.

Its clamping chuck guards against damage to the motor, gearbox, cylinder, and roller. It also improves production efficiency by eliminating the need for worn-out parts replacement.

The shaftless unwinder has a mechanically expandable chuck for easy paper clamping. To accommodate current paper core sizes, shaftless unwinder chuck sizes are primarily 3-inch, 6-inch, and 12-inch.

Knives For Pneumatic Action

The paper knives are the most important part of a paper slitting machine.To meet our customers’ needs, we offer a variety of knife mechanisms, including pneumatic knives, round disc knives, and razor blades. The type of knife mechanism used on the slitter rewinder is determined by the final product of the customer.

On our new type of paper rewinder, we installed 5 sets of pneumatic knives.

Pneumatic knives, also known as blade knives, use a thin sheet and high-speed pressure to cut paper rolls.
They are ideal for rewinding long lengths of paper as well as difficult materials such as corrugated cardboard, paper cardboard, or plastic film.

During normal operation, the slitter knife must be able to withstand high temperatures and frequent knife changes.

The pneumatic knives are made of stainless steel and the raw material of SS with Teflon, and each is a high-hardness JISSK-180 steel that outperforms a regular knife./p>

The knife is designed for more precise slitting and bending, increasing rewinding efficiency by 30% compared to other machines.

Meanwhile, when the running speed exceeds 500 mph, the pneumatic function is stable, and the knife vibration is less than 2 micros. It will guarantee that the slitting edge effect is obtained.

It has good heat dispersion functions, so the knives do not get hot when running at high speeds. As you may be aware, getting hot or working in high temperatures for an extended period will reduce the working life of the knife.

Pneumatic Knife: Unlike other cutting methods, the pneumatic knife has a simple and effective structure. To begin, apply pneumatic pressure; second, a sharp knife blade is easily replaced and changed.

Structure Of Surface Rewinding

Surface rewinding is ideal for heavy-duty paper rewinding or material feeding. To set up the surface rewinding structure, it has two bottom rollers and one lay-on roller.

The stainless-steel pipe with a diameter of 400mm to 450mm and a wall thickness of 30mm is well welded around the two bottom rollers. The roller is also well treated by static and dynamic balancing, which ensures no vibration when running at high speeds. It is also important to ensure the accuracy of your rewinding.

It is capable of handling long lengths of paper rewinder without damaging rollers or idler rollers.

The surface type paper rewinder is suitable for binding soft papers such as newspapers, magazines, and catalogues.It can also be used to bind hard paper, such as cereal boxes, corrugated paper, kraft paper cardboard, and similar items.

Surface winding slitting machines are typically used in conjunction with a specific type of binder to produce high-quality finished bound products.

Paper Rewinder Servo Motor

We made a few changes to the surface type rewinding structure.

In order to increase power and efficiency, we installed three asynchronized servo motors for rewinding. It has high stability and efficiency in both synchronous and asynchronous modes.

With servo motors, you get more power and smaller installation spaces. This machine is suitable for smothering light paper or kraft paper cardboard production lines in many factories. This is our newest design product, and it has already been released to the market.

Because of its stable instantaneous load and high sensitivity, our rewinder uses servo motors to provide a more efficient and effective operation. It effectively prevents material from wrapping around the rewinder’s roll shaft, which is caused by an inefficient asynchronous motor.

A servo motor can reduce energy consumption by up to 30% while increasing capacity.

We use a single PLC to control three servo motors that have a maximum running speed of 1200m/min.
