In manufacturing industries such as 3C electronics, food processing, automotive parts, and medical products, small belt conveyors have become an important part of automated production lines. They not only perform material transportation tasks but also affect the efficiency, positioning accuracy, and product quality of the entire production line.
Due to differences in production environments, transported materials, and process requirements, small belt conveyors have developed into various structural designs. For purchasing managers and production engineers, understanding the features and suitable applications of different conveyor types can help companies avoid incorrect selection, improve production efficiency, and reduce unnecessary costs.
SCplus Belt will introduce the main types, application scenarios, and selection points of small belt conveyors based on common industrial applications.
Small Conveyor Models for Different Production Applications
According to belt width and structural design, small conveyors can generally be divided into two main categories: wide belt conveyor series and narrow belt conveyor series.
Different models have their own advantages in load capacity, installation space, and conveying accuracy. They can meet different production requirements, from lightweight precision processing to medium-load material transportation.
Wide Belt Conveyor Series
1.Standard General-Purpose Conveyor
The standard general-purpose conveyor is the most widely used basic model in factory automation production lines.
It adopts a single-slot aluminum profile structure with a 20mm pulley design, and the load capacity can reach 0-200KG. By adding guide strips and curved rollers, the conveyor uses a double anti-deviation design to improve belt running stability and ensure better contact between the belt and rollers.
This type of conveyor is especially suitable for transporting small electronic components, precision parts, and other materials in limited installation spaces.
2.Built-in Motor Conveyor
The built-in motor conveyor focuses more on efficient space utilization.
It adopts a double-slot aluminum profile structure with a 30mm pulley design, and the maximum load capacity can reach 100KG.
The hidden motor installation makes the overall structure more compact and reduces the impact of external equipment on conveyor operation.
It is commonly used in mobile phone assembly lines, tablet computer production lines, and small medical consumable manufacturing lines.
3.Conveyor with Customized Side Plates
The conveyor with customized side plates is mainly used in production processes that require material separation, sorting, or inclined transportation.
With a 50mm large pulley design, it can transport materials with a load range of 0-20KG. According to actual requirements, dividing strips can be added to effectively prevent products from falling and improve conveying stability.
This type of conveyor is commonly selected for food sorting lines, daily chemical product packaging, and product classification applications.
4.Vision Backlight Conveyor
The vision backlight conveyor is specially designed for automated inspection stations and is suitable for lightweight products with a load capacity of 0-10KG.
The conveyor uses a transparent belt combined with a parallel light source installed underneath, providing a stable inspection background for industrial cameras and improving visual inspection accuracy.
By working with CCD cameras or machine vision systems, it can automatically detect product dimensions, surface defects, and other quality problems.
It is widely used in inspection production lines for chips, electronic components, and precision mechanical parts.
Narrow Belt Conveyor Series
1.Single-Row Narrow Belt Conveyor
The single-row narrow belt conveyor is mainly designed for high-precision and lightweight conveying applications.
It adopts a 19mm small pulley design, with a load capacity usually ranging from 0-10KG. The inner layer of the belt uses a fabric reinforcement structure, which effectively reduces operating noise and improves conveying stability.
Due to its compact size and high positioning accuracy, it is especially suitable for precision products with strict requirements for the conveying environment, such as watch components, small jewelry parts, medical needles, and small batteries.
For automated production lines with limited space and requirements for low noise and accurate positioning, the single-row narrow belt conveyor is an ideal solution.
2.Double-Row Narrow Belt Conveyor
The double-row narrow belt conveyor adopts a synchronous running structure with double toothed belts.
Compared with the single-row design, it provides higher load capacity and better conveying stability. The maximum load capacity can reach 100KG, while maintaining good positioning accuracy.
This type of equipment is suitable for transporting materials such as electronic component trays and small automotive parts.
After using wear-resistant rubber belts, it can reduce surface damage to products, making it especially suitable for products with high surface protection requirements, such as photovoltaic components and glass panels.
Common Belt Materials Used in Small Belt Conveyors
The conveyor belt is the core component of a belt conveyor that directly contacts the transported materials. It is also one of the main wearing parts during equipment operation.
Generally, the conveyor belt accounts for about 30%-50% of the total conveyor cost. Therefore, choosing the right belt material directly affects the equipment service life, operating stability, and future maintenance costs.
At present, the commonly used belt materials for small belt conveyors mainly include PVC, PU, rubber, and mesh belts. Different materials have different advantages in terms of wear resistance, cleaning requirements, load capacity, and application environments.
Common conveyor belt materials include PVC belts, PU belts, rubber belts, and mesh belts. Each material has its own characteristics in terms of wear resistance, load capacity, and suitable working conditions.
For applications where the conveyor belt directly contacts food products, it is recommended to select food-grade conveyor belts that meet food safety requirements.
For short-distance and lightweight conveying applications, polyester fabric core belts are usually enough to meet production needs.
However, for long-distance and heavy-load transportation, steel cord conveyor belts are a more reliable choice due to their higher load capacity and better stability.
How to Choose the Right Conveyor Speed?
The conveyor speed is not always better when it is faster. It should be selected according to the characteristics of the transported materials.
For low-wear bulk materials, the conveying speed can be set between 2-4m/s.
For fragile materials, the speed is recommended to be controlled between 1.25-2m/s to reduce material impact and prevent damage.
For powder materials with a large amount of dust, low-speed operation at ≤1.0m/s can help reduce dust problems.
At the same time, when the conveyor installation angle becomes larger, the conveying speed should be reduced appropriately to reduce the risk of material sliding and ensure a more stable transportation process.
How to Choose a Small Belt Conveyor According to the Drive Method?
According to different drive methods, small belt conveyors can mainly be divided into two types:
* Variable frequency speed control conveyors
* Servo-driven conveyors
Both types have their own advantages and are suitable for different production requirements.
Variable Frequency Speed Control Conveyor
Variable frequency speed control conveyors provide high cost performance.
The conveying speed can be adjusted flexibly according to production requirements, making them widely used in logistics sorting lines, standard assembly lines, and other applications where speed adjustment is frequently required.
This type of conveyor is a practical choice for general automated production processes that need flexible speed control.Servo-Driven Conveyor
Servo-driven conveyors focus more on precise control and positioning performance.
The positioning accuracy can reach ±1mm, making them suitable for precision assembly processes that require fixed-point transportation and intermittent feeding.
Typical applications include automated assembly equipment, precision processing production lines, and other manufacturing processes with strict positioning requirements. From the structural perspective, small belt conveyors can also be divided into different types, such as flat belt conveyors and cleated sidewall conveyors.
According to different conveying direction requirements, they can also be designed as one-way conveyors and bidirectional conveyors.
Bidirectional Conveyor
Bidirectional conveyors require reversible motors and double-sided wear-resistant belts to meet the requirements of forward and reverse operation.
Compared with standard one-way conveyors, bidirectional conveyors have higher requirements for control system design because the operating logic needs to ensure stable transportation in both directions.
They are suitable for production lines that require flexible material transfer between different working stations.
Belt Tension Adjustment Structure
In addition, most belt conveyors are equipped with tension adjustment structures to maintain stable belt tension and prevent belt slipping or deviation during operation.
For short-distance conveying lines, a manual screw tensioning system is usually sufficient to meet production requirements.
For long-distance and heavy-load conveying applications, counterweight tensioning systems or automatic pneumatic tensioning devices can further improve equipment stability and reduce the frequency of manual maintenance.
What Factors Should Be Considered When Selecting a Small Belt Conveyor
Before selecting the equipment, companies should consider four key factors:
* Material size and weight
* Production efficiency and accuracy requirements
* Available installation space in the workshop
* Project budget
These factors can help companies choose a conveyor that better matches their actual production requirements.
For bulk purchases of more than 10 units, many manufacturers can usually shorten the delivery time to within 7 days, which helps customers meet production schedules more efficiently.
Although small belt conveyors have a compact structure, they play an important role in automated production lines.
From wide belt conveyors to narrow belt conveyors, and from standard material transportation to visual inspection applications, different conveyor structures are designed for different production scenarios.
When selecting a small belt conveyor, companies should make a comprehensive evaluation based on product characteristics, production efficiency, installation space, and future expansion requirements.
Choosing the right small belt conveyor can not only improve production line efficiency but also reduce equipment maintenance costs and provide reliable support for long-term stable production.
