Paper Circular Slitter Blades

Paper cutter blades are widely used in the fields of food packaging, electronic component protective film processing and corrugated board production. Through material innovation and process optimization, it covers the whole scene requirements from basic paper cutting to high-precision industrial cutting.

1.Printing and office paper cutting: The flat knife cutting machine adopts rectangular blades (the blade angle is 20-30), and the coated paper, A4 paper, etc. can be processed in batches through the hydraulic drive system (cutting force of 50-200 tons), and more than 500 sheets can be cut at a time, which meets the whole edge demand before book binding. The circular cutter uses the rotating blade with a diameter of 100-300mm and cooperates with the magnetic powder tension control technology to realize the cutting of large roll base paper into narrow roll paper, and the cutting speed reaches 200-300 m/min.

2.Packaging material processing: the circular blade is used for cutting packaging materials such as aluminum foil, composite film and corrugated board, with the cutting accuracy of ±0.1mm, which is suitable for synchronous operation of high-speed sealing machine. The serrated blade is designed for hard materials (such as plastic plates and thick cartons). By reducing the cutting resistance, the cutting flatness is improved, and the cut burr rate is ≤0.5%.

3.Industrial-grade paper processing: CNC cutting machine integrates oblique blade and laser positioning system, and completes special-shaped cutting of label paper, artistic cardboard, etc. The error is controlled within ±0.05mm, which is suitable for high-end packaging and cultural and creative product production. In the automatic production line, the paper cutting blade is linked with the paper receiving technology to realize the continuous cutting of the coil, and the tension fluctuation of the paper roll is ≤5%.

1. Straight blade

Linear cutting edge: suitable for cutting full-sheet, folio and other large-format papers, with a width range of 400-1270mm and a thickness of 12.7-25.4mm, and the cutting accuracy can be controlled within ±0.1mm；;

Single-sided/double-sided blade design: the angle of single-sided blade is ∠ 19 ~ 23 (conventional cutting), which reduces cutting resistance and improves wear resistance.

2. wavy blade

Corrugated cutting edge: used for decorative cutting or improving paper adsorption, reducing adhesion of cutting surface and adapting to composite materials such as packaging paper and film; Special technology: chromium plating or titanium coating treatment on the surface to enhance corrosion resistance and prolong service life.

3. circular blade

Integral disc shape: suitable for web cutting, toilet paper rotary cutting and other scenes, with a diameter of 610mm；;

Dynamic cutting: High-speed rotating cutter sets form continuous cutting force, which is suitable for high-frequency operation of assembly line, and the cutting frequency reaches dozens of times per second.

4. serrated blade

Toothed cutting edge: the tooth height is 0.8-2mm, which is specially used for cutting hard materials (such as cardboard and adhesive tape) to reduce the risk of edge collapse;

Functional subdivision: including lace serrated knife (decorative cutting) and sealing machine toothed knife (packaging and sealing).

5. special-shaped blade

Customized design: such as dotted circular knife (easy-to-tear cutting) and butterfly cutting knife set (symmetrical cutting), etc., to meet special cutting needs; Composite technology: adopt steel-inlaid composite structure (cutting edge cemented carbide+tool body ductile steel) to balance durability and cost.

Through reasonable matching of material and technology, the blade of paper cutter can meet the diversified needs of printing, packaging and other industries, and improve cutting efficiency and finished product quality.

Grinding requirements:

The grinding angle of double-sided edge should be < ∠ 19, and the higher the finish, the smaller the cutting resistance and the more than 90% of the performance after grinding.

Wear management:

The cutting edge of cemented carbide blades needs to be checked every 100,000 times, and high-speed steel blades are recommended to be turned over every quarter to avoid paper burrs caused by passivation;

Automated maintenance:

High-end models are equipped with built-in sharpeners, such as BERKEL B114, which can automatically repair the cutting edge and reduce downtime.
