What is a Tobacco Industry Blade?

A tobacco blade is a specialized tool for processing tobacco products. It participates in links like cutting tobacco leaves, shaping cigarette sticks, and packaging cigarette boxes. There are types such as straight blades for cutting tobacco leaves and filter rods, circular blades for cutting cigarette sticks, and special – shaped blades for cigarette box packaging. Made of materials like high – speed steel and cemented carbide, parameters such as blade angle and thickness can be adjusted according to tobacco processing needs. It is a key component in the tobacco production line, ensuring cutting accuracy, product quality, and production efficiency.

What are the common tool types used in Tobacco slitting?

Using different tobacco slitting knives allows for precise matching of diverse tobacco processing stages (such as raw material cutting, shredding, and packaging), addressing varying material properties and process requirements, thereby ensuring cutting quality, production efficiency, and product consistency.

Circular Blade Type

Structural Feature：Presents a circular structure, with a central hole for installation on rotating shafts. The cutting edge is a continuous circular ring. The blade body has consistent thickness and realizes cutting by rotating along with the shaft.
Functional Advantage：During tobacco shredding and cutting operations, the rotary cutting is stable and efficient. It can ensure uniform tobacco shred width and smooth cutting surfaces, suitable for high – speed tobacco processing lines. It reduces problems like uneven shredding and material jamming, maintaining stable production.
Typical Applications：In tobacco primary processing and shred production lines, it is used for cutting tobacco leaves, stems into shreds or slices. For example, in large – scale tobacco processing workshops, it cuts large batches of tobacco raw materials into qualified shreds for subsequent cigarette production; also used for slitting wide – width tobacco sheets into appropriate sizes according to production needs.

Straight Blade Type

Structural Feature：Has a linear – shaped cutting edge, with a flat and straight blade body. It can be installed on fixed or reciprocating – motion tool holders. The blade has a certain length and thickness to ensure cutting strength.
Functional Advantage：When cutting tobacco, it can achieve precise linear cutting, ensuring accurate cutting dimensions. It has good adaptability for cutting operations of different tobacco materials, like cutting tobacco leaves into specific shapes or cutting tobacco shreds to fixed lengths. The simple structure makes it easy to maintain and sharpen.
Typical Applications：In tobacco fine – processing links, such as cutting tobacco shreds to fixed lengths in cigarette making machines, or cutting tobacco leaves into regular shapes in tobacco leaf sorting and trimming processes; also used for cutting packaging materials in tobacco packaging production lines, like cutting cigarette box wrapping paper.

Guillotine Blade Type

Structural Feature：Features a vertical – moving blade structure, usually with a rectangular or square blade body. It is installed on a frame – like tool holder and realizes cutting by vertically pressing down, similar to a guillotine – like motion.
Functional Advantage：When cutting bulk tobacco materials or thick tobacco products, it can exert large cutting force, achieving rapid and effective cutting. It is suitable for cutting operations requiring large impact force, like cutting large bundles of tobacco stems or cutting thick tobacco blocks, ensuring smooth and neat cutting sections.
Typical Applications：In tobacco primary processing, it is used for cutting large bundles of tobacco stems into small sections for subsequent processing; in tobacco packaging production, it can be used for cutting thick packaging materials or cutting large – size tobacco products into specified dimensions, such as cutting thick tobacco – filled blocks into appropriate sizes for cigarette production.

What are the common working methods?

Different cutting methods can precisely adapt to the material characteristics and process requirements of each tobacco processing link, ensuring cutting quality and production efficiency.

Guillotine Cutting

Principle: Similar to the vertical downward “chopping” action of a guillotine blade, it uses a relatively large impact force to cut bundled and relatively hard tobacco stems at one time.
Scenario: During the primary processing of tobacco, large bundles of tobacco stems (such as those over 1 meter in length) purchased are cut into small segments (5 – 10 cm) to facilitate subsequent shredding and ingredient extraction.
Advantage: Strong cutting force, suitable for thick and hard materials; simple structure, and low cost of equipment (such as tobacco guillotine machines).

Roller Cutting

Principle: Multiple sets of circular blades cooperate with supporting rollers. When tobacco stems pass through the gap between the rollers, the cutting edges of the high – speed rotating circular blades “mill” the stems into segments.
Scenario: In the tobacco stem pretreatment production line, the initially cut tobacco stems are further cut into more uniform small segments (such as 2 – 3 cm) to prepare for shredding.
Advantage: Continuous cutting, high efficiency, and better segment size precision than guillotine cutting (with an error within ±1 mm); suitable for large – scale assembly lines.

Rotary Shredding

Principle: A high – speed rotating circular blade (or combined cutter head) cooperates with a fixed bottom blade to “shear + mill” tobacco leaves/tobacco stems into filaments.
Sub – scenarios:
- Thin Sheet Shredding: For reconstituted tobacco leaves (such as those with a thickness of 0.1 – 0.3 mm), the circular blade precisely controls the shred width (0.6 – 1.2 mm) to ensure the shape of the tobacco shreds.
- Conventional Tobacco Shredding: For processing raw tobacco leaves, by adjusting the rotational speed of the cutter roller and the feed amount, tobacco shreds of different thicknesses are cut (such as 0.6 mm for slim cigarettes and 1.0 mm for regular cigarettes).
Core Equipment: Shredding machines (such as roller – type shredding machines), which rely on the rotation of circular blades to achieve continuous shredding, accounting for more than 90% of applications in tobacco primary processing production lines.

Reciprocating Shredding

Principle: A straight blade moves back and forth along a straight line (such as horizontal pushing and pulling, vertical lifting), cutting tobacco leaves like a “scissor”.
Scenarios:
- In the production of small – batch, customized tobacco shreds (such as hand – made cigar tobacco shreds), the straight blade can flexibly adjust the shred length and angle to meet the needs of special formulations.
- “Secondary trimming” of tobacco shreds, such as removing overly long and overly short tobacco shreds, to ensure the consistency of the length of the finished tobacco shreds (with an error within ±0.5 mm).
Advantage: High cutting precision and strong flexibility, suitable for the processes of niche and high – end tobacco shreds; however, the efficiency is lower than that of rotary shredding, and it is mostly used for “completing the process”.

Die - cutting

Principle: Combined cutters (including straight blades and special – shaped blades) move according to the mold trajectory to “punch – cut” the outer wrapping paper, inner lining paper, etc. of cigarette packs, and form the required shape at one time (such as the flip cover of cigarette packs, serrated openings).
Scenario: In the cigarette pack packaging production line, aluminum foil paper and cardboard are cut to the precise size of cigarette packs, or easy – tear openings are cut on cigarette packs.
Key Point: The cutters need to be strictly adapted to the mold to ensure smooth notches and regular shapes (such as the error of the spacing of easy – tear openings is less than 0.2 mm) and avoid cracking of the packaging cardboard.

Slitting

Principle: Circular blades are responsible for continuously slitting long – roll packaging materials (such as cigarette paper, BOPP film), and straight blades assist in cutting to a fixed length to ensure that the length of the packaging material for each pack of tobacco is consistent.
Scenarios:
- Slitting of cigarette paper: Cutting large rolls of cigarette paper (with a width of more than 1 meter) into narrow strips (with a width of 27 – 30 mm) for single cigarettes.
- Slitting of cigarette pack wrapping film: Cutting continuous wrapping film materials to the length of cigarette packs (such as 100 – 110 mm for 84 – mm cigarettes) for bagging and packaging.

What materials can be used to make cutting blades?

Tobacco blades made from different materials are designed to adapt to the performance requirements of various tobacco processing stages, balancing cost and efficiency to ensure production reliability.

What parameters do we need to understand?

Defining parameters such as material, hardness, dimensions, precision, and service life of tobacco blades is crucial for achieving precise matching between blades and equipment/process requirements, ensuring production efficiency, product quality, and cost control.

Category	Parameter	Description
Basic Performance Parameters	Material	Specify high-carbon steel, stainless steel, alloy steel, cemented carbide, zirconia ceramic, etc., which determine hardness, wear resistance, and corrosion resistance to match different processing scenarios (e.g., cemented carbide suits high-precision tobacco strip cutting).
	Hardness	Expressed in Rockwell hardness (HRC), reflecting the blade’s wear resistance and anti-deformation ability. For example, high-carbon steel can reach HRC 58-65 after heat treatment, and selection should align with processing intensity (higher hardness is preferred for tobacco shred cutting).
	Dimension Specifications	Include blade length, width, thickness, and compatible tool holder installation dimensions (shaft diameter, slot specifications) to ensure compatibility with equipment (e.g., cigarette packer tool holders have strict dimensional matching requirements).
Processing Adaptation Parameters	Cutting Precision	Such as error ranges for cut cigarette length or tobacco shred width (e.g., ±0.05 mm), affecting finished product quality (slim cigarettes are sensitive to cigarette length precision).
	Edge Design	Including finishing edges or chipbreaker types, influencing chip control and cutting surface smoothness (cigar wrapper cutting requires fine edges to avoid damage).
	Applicable Working Conditions	Cover applicable tobacco materials (tobacco leaves, filter rods, cigarette paper, etc.), processing stages (tobacco leaf sorting, cigarette rolling, etc.), and load intensity (high-toughness materials for high-load tobacco shredding).
Life and Maintenance Parameters	Service Life	Measured by continuous working hours or tobacco cutting volume (e.g., number of cigarette cuts in ten thousands), affecting usage cost and tool change frequency (long-life blades are preferred for high-speed production lines).
	Abrasion/Corrosion Resistance Indicators	Describe durability in tobacco processing environments (humid, nicotine-rich, etc.) to determine maintenance frequency (stainless steel blades prioritize corrosion resistance).
	Regrinding/Replacement Requirements	Indicate whether regrinding is possible, precision retention after regrinding, and replacement cycle recommendations, affecting long-term usability (high-carbon steel is easy to regrind, while ceramic blades are difficult to repair).
