High-Quality Patterned Rubber Conveyor Belt from China Suppliers and Factory for Efficient Material Handling
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.
- Application: Suitable for conveying materials with an inclination angle of 0–40°, preventing material from sliding down.
Commonly Used Patterned Conveyor Belts
Herringbone Pattern
Feature
There are "human" shaped patterns on the belt surface that are higher than the belt body. The patterns can be open or closed, and each pattern can be divided into three types: high, medium, and low.
Purpose
Suitable for conveying powdered, granular, and small materials with an inclination angle of ≤ 40°, as well as bagged materials.
Striped Pattern
Feature
There are strip-shaped patterns on the belt surface that are higher than the belt body, divided into three types: high, medium, and low. Each type can be further divided into sparse, dense, and other forms by arrangement spacing.
Purpose
Suitable for horizontal conveying of packaging materials with an inclination angle of ≤ 30°. When grooved, it can replace the herringbone pattern.
Granular Pattern
Feature
There are granular patterns on the belt surface that protrude from or are embedded in the belt body. Pits can also be made into square holes, edges, and cloth patterns.
Purpose
Convex granular patterns are suitable for soft packaging or materials requiring gripping force (e.g., cardboard boxes). The concave granular pattern is suitable for granular materials with an inclination angle of ≤ 45°.
Fan-Shaped Pattern
Feature
There are semi-circular (or 1/4 circular) patterns on the belt surface. When the tape is grooved, the patterns intertwine into a fan-shaped (or semi-circular) shape, belonging to the high pattern category.
Purpose
Suitable for conveying powder, particles, and block materials with a large inclination angle of ≤ 45°.
Other available patterns include: Lawn, fishbone, diamond grid, cross, mesh, inverted triangle, horseshoe, sawtooth, small dot, diamond, snake skin, cloth, large frustum, wave, washboard, straight, golf, large grid, matte, coarse texture, grid patterns, and more — each suited for specific performance requirements across diverse industrial 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 also differ. Commonly used varieties include: herringbone, octagonal, fishbone, U-shaped, cylindrical, pockmarked, etc. Designs can also be customized according to user requirements — suitable for powder, granular, and block materials with an inclination angle of less than 30°.
Maintenance of Patterned Conveyor Belts:
- Keep the belt clean during transportation and storage. Avoid direct sunlight, rain, and snow. Prevent contact with acids, alkalis, oils, and organic solvents. Maintain a distance of at least one meter from heating devices.
- Storage warehouse temperature should be maintained between 18–40 ℃, with relative humidity between 50–80%.
- During storage, the conveyor belt must be placed in rolls and not folded. It should be flipped once every quarter.
- Do not use conveyor belts of different types and specifications together. It is best to use adhesive bonding for joints.
- The type, structure, specifications, and number of layers of the conveyor belt should be reasonably selected according to usage conditions.
- The running speed of the conveyor belt should generally not exceed 2.5 m/s. For large block size materials with high abrasion and fixed unloading devices, low speed should be used as much as possible.
- The relationship between the transmission drum diameter and the fabric layer, the matching of transmission and reversing drums, and the groove angle requirements for idlers should be selected according to conveyor design regulations.
- The feeding direction should follow the running direction of the conveyor belt. Use a chute to minimize the drop distance of materials. The receiving section should shorten roller spacing and use buffer rollers to prevent material leakage. Equip the belt with a soft, moderate material blocking plate to prevent scratching the belt surface.
Precautions
With the growing adoption of conveyor belts in industrial production, multiple varieties, high performance, lightweight, multifunctional design, and long service life are key concerns for manufacturers. Correct use of conveyor belts is especially important. The following precautions should be observed:
- Avoid rollers being covered by material causing ineffective rotation. Prevent material leakage from getting stuck between the drum and the tape. Lubricate moving parts of the conveyor, but do not apply oil directly on the conveyor belt.
- Prevent the conveyor belt from starting under load.
- If the conveyor belt deviates, take timely corrective measures.
- When local damage is found on the conveyor belt, use artificial cotton for timely repair to prevent expansion.
- Avoid the conveyor belt from being blocked by the frame, pillars, or block materials to prevent collision, breakage, and tearing.
Frequently Asked Questions (FAQ)
What is a patterned conveyor belt and how does it work?
A patterned conveyor belt features a raised pattern surface on its working side and a flat surface on the non-working side. The patterns create additional friction and grip, enabling the belt to transport materials at inclined angles of 0–40° without slippage or material sliding back down.
What pattern types are available for patterned conveyor belts?
Common pattern types include herringbone, striped, granular, fan-shaped, fishbone, diamond grid, sawtooth, wave, and many more. Each pattern is designed to suit specific material types, inclination angles, and industrial application requirements. Custom patterns can also be designed upon request.
What inclination angle can a patterned conveyor belt handle?
Depending on the pattern type, patterned conveyor belts can handle inclination angles ranging from 0° up to 45°. For example, herringbone and fan-shaped patterns are suited for angles up to 40–45°, while striped patterns are typically recommended for angles up to 30°.
What materials are used in the core of patterned conveyor belts?
Patterned conveyor belt cores can be made from ordinary cotton canvas (CC), polyester-cotton blended canvas (CP), nylon (NN), or polyester (EP). The choice depends on the application's load requirements, flexibility, and environmental conditions.
How should patterned conveyor belts be stored properly?
Store patterned conveyor belts in a clean, dry environment with temperatures between 18–40 ℃ and relative humidity of 50–80%. Avoid direct sunlight, extreme temperatures, and contact with chemicals. Belts should be stored in rolls, not folded, and flipped once every quarter to prevent deformation.
What is the maximum recommended operating speed for a patterned conveyor belt?
The running speed should generally not exceed 2.5 meters per second. For applications involving large-sized, highly abrasive materials or fixed unloading devices, it is advisable to operate at lower speeds to reduce wear and extend belt service life.
