Paper Slitter Rewinding Machine Buying Guide

With the rapid development of the paper industry, paper slitting rewinding machines have ushered in a new round of technological upgrades. Slitting and rewinding machines can automatically adjust cutting speed, tension and winding density, improve production efficiency and stability, and bring significant production benefits to papermaking companies, becoming the focus of industry attention.

Know your target audience

Before purchasing any paper slitting equipment, it is important to understand who your product is for. Your audience's needs will vary depending on the needs of the industry, so choose your equipment accordingly.

Packaging paper demanders:For users who need wrapping paper, they should choose a machine that can cut kraft paper and cardboard.

Cultural paper demanders:Choose a slitting machine that can produce books, copy paper, and magazines.

Medical paper demanders:Selecting machinery for slitting and rewinding medical papers.

Selection Factors

Cutting requirements: Determine the paper type, thickness, width and other parameters to be cut, as well as the requirements for cutting accuracy. If you are cutting thicker paper, you need to choose a machine with greater cutting force; if you have high requirements for cutting accuracy, you need to choose a high-precision slitting and rewinding machine.

Production scale: Choose the appropriate equipment according to the expected production volume. If the production scale is large, choose a machine with high production efficiency.

Automation: Equipment with a high degree of automation can reduce manual operations, improve production efficiency, and reduce labor intensity and production costs. Equipment with functions such as automatic feeding, automatic cutting, automatic rewinding, and automatic counting has more advantages in large-scale production.

Accessories supply: Ensure that equipment accessories are adequately supplied and easy to purchase to reduce equipment downtime due to accessories shortage.

Cutting accuracy: High precision cutting can ensure that the paper cut is flat and smooth, without burrs, tears and other defects. This is very important for some industries that have high requirements on paper quality, such as printing and packaging.

Common fault problems

Uneven winding: This is mostly caused by the paper core being unsuitable. The paper core needs to be replaced with one that meets the required inner diameter. Using a winding roller during the winding process can also avoid this problem.

The weight of the paper rolls is different: it may be that the width of each roll is different, the basis weight profile of the base paper varies, or there is no stretching roller, causing the paper to wrinkle and increase the weight.

Burrs appear on the paper tray: When the width of the base paper does not match the size of the knife adjustment, burrs are likely to appear on the edge of the paper tray. You can stop the machine to loosen the front knife for a while and then tighten the two side knives after running for a while.

Layer misalignment: refers to the situation where part of the film is misaligned on the end surface of the film roll, which is mainly caused by the film sliding during the winding process or the change in the film width.

Automatic tube loading is abnormal: if the trolley does not push the core tube to the corresponding position of the rear section after the core tube goes down to the front track, the core tube is piled up in the front section and the automatic tube loading stops, it may be a program problem, which can be solved by online tool modification and other methods.

Conclusion

When purchasing a paper slitting and rewinding machine, you should consider the production scale, machine automation level, production demand, and accessories supply.By carefully evaluating your needs and comparing different models, you can find the right paper slitter rewinder to optimize your production process and improve efficiency.
