The design points of small belt conveyors cover multiple aspects to ensure their stability and reliability in practical applications. The following is a detailed summary of these design points:
1、 Working environment and conditions
Daily operating time and frequency:
Consider the daily operating time and frequency of the belt conveyor to select appropriate materials and structures to ensure its stability and durability during long-term operation.
service life:
Estimate the service life of the belt conveyor in order to select suitable materials and designs to meet the expected service life requirements.
Work environment:
Consider factors such as environmental temperature, outdoor or indoor conditions, and environmental requirements to ensure that the belt conveyor can operate normally under these conditions.
Mobility or fixity:
According to actual needs, determine whether the belt conveyor needs to have mobility in order to operate in different positions.
2、 Design of Conveyor Lines and Belts
Conveyor line size:
Carefully consider the size parameters such as the inclination angle, length, and lifting height of the conveyor line to ensure that the belt conveyor can meet the needs of material transportation.
Conveyor belt selection:
Select appropriate conveyor belt materials (such as rubber belts, polyurethane belts, steel belts, etc.) based on the properties of the material (such as loose density, particle size, humidity, wear resistance, etc.).
The conveyor belt should have good wear resistance, high temperature resistance, corrosion resistance and other characteristics to extend its service life.
3、 Rack and support structure
Rack design:
The rack should be made of materials with sufficient strength and good stability, such as channel steel, angle steel, and steel plate.
The design of the rack should consider ease of installation, disassembly, and maintenance.
Supporting structure:
The roller or pallet should directly support the belt and the material above it, ensuring that the belt does not sag.
The roller should adopt a structure that can rotate freely to reduce operational resistance.
4、 Transmission and tensioning device
transmission:
The transmission device should be able to provide sufficient driving force to ensure that the belt can run smoothly.
Common transmission methods include motor drive, chain drive, synchronous belt drive, etc.
Tensioning device:
The tensioning device is used to adjust the tension of the belt, ensuring that the belt does not loosen or slip during operation.
The design of the tensioning device should consider ease of adjustment and maintenance.
5、 Safety and protective measures
Anti slip device:
Install anti-skid devices such as friction wheels or magnetic wheels at key parts of the belt conveyor to prevent the belt from slipping.
Buffer device:
Install buffer devices such as rubber buffer blocks or spring buffers at both ends of the conveyor belt or at areas prone to impact to protect the conveyor belt and support frame.
Positioning baffle:
Set positioning baffles or barriers on both sides of the conveyor belt to ensure that the material always moves in a straight direction, preventing material deviation or falling.
6、 Other design points
Correction mechanism:
Belt conveyors are prone to deviation during operation, so correction mechanisms such as roller sets should be installed to ensure that the belt stays on the correct track.
Maintenance and upkeep:
When designing, equipment maintenance and upkeep should be considered, and the structure and operation should be simplified as much as possible to reduce usage and maintenance costs.
In summary, the design points of small belt conveyors involve multiple aspects such as working environment and conditions, conveyor line and belt design, frame and support structure, transmission and tensioning devices, safety and protection measures, and other design points. When designing, it is necessary to comprehensively consider these factors to ensure the stability and reliability of the belt conveyor in practical applications.

- 考虑皮带输送机每天的运转时间和工作频率，以选择适当的材料和结构，确保其在长期运行中的稳定性和耐久性。
- 使用寿命：
- 预估皮带输送机的使用寿命，以便选择合适的材料和设计，以满足预期的使用寿命要求。
- 工作环境：
- 考虑环境温度、室外或室内、环保要求等因素，以确保皮带输送机在这些条件下能够正常运行。
- 移动性或固定性：
- 根据实际需要，确定皮带输送机是否需要具备移动性，以便在不同位置进行作业。
二、输送线与输送带设计
- 输送线尺寸：
- 详细考虑输送线的倾角、长度、提升高度等尺寸参数，以确保皮带输送机能够满足物料输送的需求。
- 输送带选择：
- 根据物料的性质（如松散密度、粒度、湿度、磨损性等）选择合适的输送带材料（如橡胶带、聚氨酯带、钢带等）。
- 输送带应具备良好的耐磨性、耐高温性、耐腐蚀性等特点，以延长使用寿命。
三、机架与支撑结构
- 机架设计：
- 机架应采用强度足够、稳定性好的材料制成，如槽钢、角钢和钢板等。
- 机架的设计应考虑便于安装、拆卸和维护。
- 支撑结构：
- 托辊或托板应直接支撑皮带及皮带上方的物料，确保皮带不下垂。
- 托辊应采用能够自由转动的结构，以减少运行阻力。
四、传动与张紧装置
- 传动装置：
- 传动装置应能够提供足够的驱动力，确保皮带能够平稳运行。
- 常用的传动方式包括电机驱动、链条传动、同步带传动等。
- 张紧装置：
- 张紧装置用于调整皮带的张紧程度，确保皮带在运行过程中不产生松弛或打滑现象。
- 张紧装置的设计应考虑便于调节和维护。
五、安全与防护措施
- 防滑装置：
- 在皮带输送机的关键部位设置防滑装置，如摩擦轮或磁力轮等，以防止皮带打滑。
- 缓冲装置：
- 在输送带的两端或易产生冲击的部位设置缓冲装置，如橡胶缓冲块或弹簧缓冲器等，以保护输送带和支撑架。
- 定位挡板：
- 在输送皮带的两侧设置定位挡板或挡条，使物料始终在直线方向上运动，防止物料偏移或掉落。
六、其他设计要点
- 纠偏机构：
- 皮带输送机在运行过程中容易出现跑偏现象，因此应设置纠偏机构，如滚筒托辊组等，以确保皮带能够保持在正确的运行轨道上。
- 维护与保养：
- 设计时应考虑设备的维护和保养，尽量简化结构和操作，降低使用成本和维护成本。
综上所述，小型皮带输送机的设计要点涉及工作环境与条件、输送线与输送带设计、机架与支撑结构、传动与张紧装置、安全与防护措施以及其他设计要点等多个方面。在设计时需要综合考虑这些因素，以确保皮带输送机在实际应用中的稳定性和可靠性。
