摘 要
进入21世纪，科技发展迅猛，工业设备向高效、自动化方向不断推进，传统的半机械化操作逐步被淘汰。带式输送机作为一种连续运输设备，广泛应用于冶金、煤炭、港口、化工、电力等行业，特别适用于长距离、大运量的物料输送。该设备具有输送能力大、布置灵活、结构简单等优势。但在长期运行中，由于其连续性强，容易在输送带上产生大量热量，若不能及时控制和散热，将导致设备部件损坏、寿命缩短及运行效率下降。
为解决上述问题，本文设计一种具备良好散热性能的带式输送机结构，对关键部件进行优化，包括动力装置选型、传动系统配置、执行装置结构设计及主要零部件的参数校核。执行装置方面，设计内容主要包括输送带本体、主动滚筒与改向滚筒、托辊组、拉紧装置等。输送带作为承载与牵引机构，选用多层高强度橡胶材料；滚筒结构根据传力需求设计直径与包胶方式，确保驱动效率与防打滑性能；托辊组合理布置，提高对带体的支撑与导向能力，降低运行阻力；拉紧装置采用螺旋调节式结构，精确控制张紧力，有效维持系统稳定性与皮带初张力。
本文基于工程设计原则，对带式输送机的结构进行整体优化，使其具备运行可靠、维护简便、重量轻、效率高、节能降耗的特性，为后续应用推广和改进提供设计依据。

ABSTRACT
In the 21st century, with the rapid development of science and technology, industrial equipment has been continuously promoted in the direction of high efficiency and automation, and the traditional semi mechanized operation has been gradually eliminated. As a continuous transportation equipment, belt conveyor is widely used in metallurgy, coal, port, chemical industry, electric power and other industries, especially for long-distance and large volume material transportation. The equipment has the advantages of large conveying capacity, flexible layout and simple structure. However, in the long-term operation, due to its strong continuity, it is easy to generate a large amount of heat on the conveyor belt. If it cannot be controlled and dissipated in time, it will cause damage to equipment components, shorten service life and reduce operation efficiency.
In order to solve the above problems, this paper designs a belt conveyor structure with good heat dissipation performance, and optimizes the key components, including power device selection, transmission system configuration, actuator structure design and parameter verification of main parts. In terms of the actuator, the design mainly includes the conveyor belt body, the driving roller and the reversing roller, the idler group, the tensioning device, etc. As the bearing and traction mechanism, the conveyor belt is made of multi-layer high-strength rubber materials; The diameter and rubber coating method of the roller structure are designed according to the force transmission requirements to ensure the driving efficiency and anti slip performance; The idler is arranged in combination to improve the support and guidance ability to the belt body and reduce the running resistance; The tensioning device adopts a spiral adjusting structure to accurately control the tensioning force and effectively maintain the stability of the system and the initial tension of the belt.

设计要求
本带式输送机设计以实现长时间稳定运行为目标，传动系统需匹配整机的输送能力与运行速度。输送带设计线速度为1.0 m/s，配套滚筒直径为0.8 m，由此计算得到滚筒转速应控制在48 r/min左右。系统需选择能够输出稳定转速的驱动电机，同时应满足高起动力矩需求，防止负载起动时出现打滑或动力不足现象。电机功率选取范围为3.0–4.0 kW之间，输入转速设定为1500 r/min，结合总传动比需求，传动系统设计传动比需达到30左右。
