Introduction
A patterned conveyor belt is an inclined conveyor belt composed of a patterned covering adhesive on the working surface and a flat covering adhesive and belt core on the non working surface.
Pattern Conveyor Belt · Features
- Core Materials: Ordinary cotton canvas (CC), polyester cotton blended canvas (CP), nylon (NN), polyester (EP), etc.
- Bandwidth: 300–800 mm
- Pattern Height: 5, 10, 15, 20 mm — Pattern shape can be designed according to user requirements.
- Features: Suitable for conveying materials with an inclination angle of 0–40°, preventing material from sliding down.
Commonly Used Patterned Conveyor Belts
🔸 Herringbone Pattern
Feature: "Human"-shaped patterns on the belt surface, higher than the belt body. Can be open or closed; divided into high, medium, and low types.
Purpose: Suitable for conveying powdered, granular, and small materials with an inclination angle of ≤ 40°, as well as bagged materials.
🔶 Striped Pattern
Feature: Strip-shaped patterns on the belt surface, divided into high, medium, and low types, with sparse, dense, and other arrangements.
Purpose: Suitable for horizontal conveying of packaging materials with an inclination angle of ≤ 30°. If grooved, can replace herringbone pattern.
🟢 Granular Pattern
Feature: Granular patterns that protrude or are embedded in the belt body; pits can be made into square holes, edges, and cloth patterns.
Purpose: Convex patterns for soft packaging or gripping-force materials; concave patterns suitable for granular materials with inclination angle ≤ 45°.
🔹 Fan-Shaped Pattern
Feature: Semi-circular (or 1/4 circular) patterns on the belt surface. When grooved, the pattern forms a fan-shaped (or semi-circular) shape; belongs to the high pattern category.
Purpose: Suitable for conveying powder, particles, and block materials with an inclination angle of ≤ 45°.
Other Available Patterns
Lawn patterns, fishbone patterns, diamond grid patterns, cross patterns, mesh patterns, inverted triangle patterns, horseshoe patterns, sawtooth patterns, small dot patterns, diamond patterns, snake skin patterns, cloth patterns, large frustum patterns, wave patterns, washboard patterns, straight patterns, golf patterns, large grid patterns, matte patterns, coarse texture patterns, grid patterns, etc. — suitable for different performance requirements in various industrial working environments.
Composition and Variety
Composition
The patterned conveyor belt consists of two parts: the base belt and the patterned belt.
Common Varieties
Due to different materials being transported and varying inclination angles, the required pattern shape and height are also different. Commonly used varieties include: herringbone, octagonal, fishbone, U-shaped, cylindrical, pockmarked, etc. — or designed according to user requirements, suitable for patterned conveyor belts for powder, granular, and block materials with an inclination angle of less than 30 degrees.
Maintenance of Patterned Conveyor Belts
- Keep the belt clean during transportation and storage. Avoid direct sunlight or rain/snow immersion, and prevent contact with acids, alkalis, oils, and organic solvents. Maintain a distance of at least one meter from heating devices.
- Warehouse temperature during storage should be maintained between 18–40°C, with relative humidity between 50–80%.
- Conveyor belts must be stored in rolls — do not fold. Flip once every quarter during storage.
- Do not mix conveyor belts of different types and specifications. Use adhesive bonding for joints whenever possible.
- Reasonably select the type, structure, specifications, and number of layers according to actual usage conditions.
- Running speed should generally not exceed 2.5 meters per second. For large block or high-wear materials, or fixed unloading devices, use low speed as much as possible.
- Reasonably select the transmission drum diameter, drum matching, and idler groove angle according to conveyor design regulations.
- Feeding direction should follow the belt's running direction. Use a chute to minimize material drop distance. Shorten roller spacing in the receiving section and use buffer rollers. Equip with a soft, moderate material-blocking plate to prevent surface scratches.
Precautions
With the popularization of conveyor belts in industrial production, multiple varieties, high performance, lightweight, multifunctional, and long service life are key concerns for manufacturers. The following precautions should be observed when using conveyor belts:
⚠️ Important Usage Notes
-
1
Avoid rollers being covered by material, causing ineffective rotation. Prevent material leakage from getting stuck between the drum and tape. Ensure proper lubrication of moving parts — but do not oil the conveyor belt itself.
-
2
Prevent the conveyor belt from starting under load.
-
3
If the conveyor belt deviates, take timely corrective measures.
-
4
When local damage is found on the conveyor belt, use artificial cotton for timely repair to prevent expansion.
-
5
Avoid the conveyor belt from being blocked by frames, pillars, or block materials to prevent collision, breakage, and tearing.
Frequently Asked Questions (FAQ)
Q
What is a patterned conveyor belt and how does it differ from a standard conveyor belt?
A patterned conveyor belt features a patterned covering adhesive on its working surface and a flat covering adhesive on its non-working surface. Unlike standard flat conveyor belts, it is specifically designed for inclined transportation, with raised surface patterns that prevent materials from sliding back during conveying at angles up to 40°.
Q
What inclination angles are patterned conveyor belts suitable for?
Different pattern types support different inclination ranges. Herringbone and striped patterns handle inclinations up to 40° and 30° respectively, while granular and fan-shaped patterns can handle up to 45°. In general, patterned conveyor belts are suitable for inclination angles of 0–45° depending on the pattern type selected.
Q
What core materials are available for patterned conveyor belts?
Patterned conveyor belts are available with several core material options, including ordinary cotton canvas (CC), polyester cotton blended canvas (CP), nylon (NN), and polyester (EP). The choice of core material depends on the specific load requirements, operating environment, and performance expectations of the application.
Q
How should patterned conveyor belts be stored properly?
Patterned conveyor belts should be stored in rolls (never folded) in a clean, dry warehouse with temperatures between 18–40°C and relative humidity of 50–80%. They should be kept away from direct sunlight, rain, snow, acids, alkalis, oils, organic solvents, and heat sources. Belts should be flipped once every quarter during long-term storage.
Q
Can patterned conveyor belts be customized to specific pattern shapes and sizes?
Yes. While standard pattern types such as herringbone, striped, granular, and fan-shaped are widely available, custom pattern shapes and heights can be designed according to specific user requirements. Bandwidth ranges from 300–800 mm and pattern heights of 5, 10, 15, and 20 mm are commonly offered.
Q
What are the most important precautions to extend the service life of a patterned conveyor belt?
Key precautions include: avoiding starting the belt under load, not mixing belts of different types and specifications, keeping the belt running speed under 2.5 m/s, repairing any local damage promptly, ensuring feeding direction aligns with belt direction, and using buffer rollers in the receiving section to reduce impact. Proper lubrication of moving parts (excluding the belt surface) and regular inspection for deviation are also essential.
