Guillotine Blades For Paper Industry

1.Roll cutting: the mother roll of wide paper is cut into multiple rolls of narrow finished products by high-speed circular cutter to meet the continuous production requirements of adhesive products, label paper and so on; In the process of cutting, it is necessary to dynamically adjust the blade spacing to ensure that the cutting width error is ≤ 0.5 mm.

2.Roll-dividing processing: the paper with large roll diameter is cut into small roll diameter materials according to the preset length, which is suitable for mass production of toilet paper and printed coil materials; Combined with tension control system (such as magnetic powder clutch) to avoid paper folding or breaking.

3.Trimming and trimming: cutting off the surplus leftover materials (such as the edges of coated paper) in the paper composite process to improve the flatness and aesthetics of finished products.

1.Processing of printed matter and office paper: flat knife cutting machine: rectangular blade (blade angle 20-30) is adopted, and coated paper and A4 paper are processed in batches through hydraulic drive system (cutting force 50-200 tons), and more than 500 sheets can be cut at a time, meeting the whole edge demand before book binding.

2.Circular cutter: equipped with rotating blades with a diameter of 100-300mm, combined with magnetic powder tension control technology, the large roll of base paper is cut into narrow web with a cutting speed of 200-300 m/min, which is suitable for high-speed printing production line.

3.Cutting of packaging materials: hard packaging materials such as corrugated board and cardboard are cut with serrated blades, which reduces the risk of material tearing, and the cut burr rate is ≤0.5%. In the cutting of composite film, the circular blade can cut without burrs with micron precision (±0.1mm), which is suitable for synchronous operation of sealing machine.

4.Continuous slitting of coiled material: In the automatic production line, the slitting blade is linked with the automatic paper receiving technology to realize continuous slitting of coiled material, and the tension fluctuation of paper roll is ≤5%, thus reducing material waste. The laser positioning system cooperates with the oblique blade to finish the special-shaped cutting of label paper and art cardboard, and the error is controlled within ±0.05mm, which is suitable for high-end packaging production.

5.Special paper processing: the anti-sticking coating blade is used for cutting release paper and adhesive tape backing paper to avoid material adhesion and adapt to adhesive products industry.

6.Ultrasonic blade (vibration frequency is 20-40kHz) is used to cut multi-layer composite paper, reducing cutting debris and improving cutting cleanliness.

1.High-speed steel (HSS): wear resistance and toughness are balanced, which is suitable for cutting ordinary paper and thin plastic film at medium and low speed, with high cost performance;

2.Cemented carbide (tungsten carbide): with extremely high hardness (HRA89-93) and excellent wear resistance, it is suitable for high-speed cutting (≥ 100m/min) of high-weight paper, film covering material and metal foil;

3.stainless steel: strong corrosion resistance, suitable for high humidity or food packaging scenes, to avoid metal pollution, but low hardness and wear resistance.

4.ceramic blade: high hardness, corrosion resistance and low friction coefficient, suitable for cutting aseptic packaging paper with high hygiene standards, but brittle and easy to break;

5.plastic/polyurethane blade: lightweight and low cost, suitable for disposable label paper or low-strength cutting requirements.

6.Alloy-inlaid blade: A hard alloy cutting edge is inlaid on the steel substrate, which is suitable for high-precision cutting such as corrugated board and coated paper in combination with strength and wear resistance;

7.Titanium nitride coated blade: the surface coating reduces the cutting resistance, prolongs the service life and is suitable for high-strength continuous operation.

1.Square shaped slitting blade: Applicable scenarios: slitting of rigid materials such as thick paper and corrugated cardboard; Features: Single sided blade: The blade has a single-sided cutting edge and is suitable for cutting rigid materials with a thickness of 70-130 μ m. It has strong stability during high-speed operation and reduces displacement; Double sided blade: Double sided cutting, better flexibility, suitable for thin paper with a thickness of 70 μ m or less, improving the flatness of cutting edges.

2.Round blade shaped slitting blade: Applicable scenarios: high-speed slitting (≥ 100 meters/minute), high-precision paper cutting (such as label paper, book pages);

3.Features: Combination cutting of upper and lower circular knives (rolling cutting principle), suitable for paper with a thickness of 100 μ m or more; The edge of the round blade is free of burrs and suitable for continuous rolling operations.

4.Butterfly blade: Applicable scenarios: thin paper sheets, high-precision cutting requirements (such as printed materials, packaging paper boxes); Features: The blade has a butterfly shaped symmetrical design, with low cutting resistance, improving cutting stability and efficiency.

Printing industry: Round knife slitting machine is used for printing roll paper production, suitable for the matching needs of offset printing machines and flexographic printing machines, with a slitting width error of ≤± 0.1mm.

Packaging industry: serrated blade for cutting corrugated cardboard, compatible with carton forming machines, capable of processing 1.5-2 tons of raw materials per hour.

Label manufacturing: CNC slitting machine achieves high-precision slitting of label paper, suitable for RFID tag and adhesive label production.

The paper slitting machine blade covers the full range of slitting needs from basic office paper to high-end industrial paper products through material optimization and process innovation.

1.Select by paper thickness:

Thick cardboard/corrugated paper: prefer single-sided square blades or alloy round blades;

Thin paper/label paper: Use double-sided square blades or butterfly blades.

2.Select according to the cutting speed:

High speed slitting (≥ 100 meters/minute): Round blades have better wear resistance and reduce downtime maintenance frequency;

Medium low speed slitting: Square blades have lower costs and are suitable for small and medium-sized production.

3.Handling of special needs:

High precision cutting: Butterfly shaped blades or hard alloy round blades can reduce burrs and improve the quality of finished products;

Hygiene standard requirements: Stainless steel round blades or coated blades are suitable for cutting food packaging paper.

By selecting the blade shape reasonably, the efficiency of paper cutting and the quality of finished products can be significantly improved, meeting the production needs of different thicknesses, speeds, and accuracies.

1.Material selection: Carbon steel blade: Low cost, suitable for cutting ordinary paper at medium and low speeds, requiring frequent polishing and maintenance; Hard alloy blade: excellent wear resistance, suitable for high-speed cutting of high weight paper or laminated paper, with a lifespan extended by more than 3 times.

2.Lubrication and maintenance: After completing each cutting task, the cutting edge is automatically lubricated with paraffin lubrication components to reduce friction loss; Regularly check the blade clearance, use rubber pads to absorb shock and adjust cutting accuracy to avoid paper layering or uneven cutting surfaces.

By optimizing blade materials, processes, and maintenance strategies, paper slitting machines can efficiently adapt to diverse production needs, balancing efficiency and cost.
