轧机上的工作辊道又有输入辊道和输出辊道之分，在轧件进辊之一方称为输入辊道，出辊之一方称为输出辊道。即从加热炉至热轧机者称为输入辊道，从热轧机至下工序者称为输出辊道，在输出和输入辊道的两端延长部分称为延伸辊道。

The work roller table on the rolling mill is also divided into the input roller and the output roller. One side of the roll is called the input roller, and one of the out rolls is called the output roller. That is to say, from heating furnace to hot rolling mill, it is called input roller table. From hot rolling mill to next process, it is called output roller table, and the extension part at both ends of output and input roller is called extended roller table.

皮带输送机生产厂家在进行设计带式输送机时，优先采用长距离、大运量输送机。皮带输送机从经济上节省占地等方面进行考虑一般不设置输送线并行的输送方式在特别重要的环节当中也有采用并行两条输送，其中一条备用，用都是采用多条输送机进行串联。

Belt conveyor manufacturers in the design of belt conveyor, the priority is to use long distance, large capacity conveyor. Belt conveyor from the economy to save an area of land and other aspects of the belt conveyer in general does not set the transmission line parallel transport mode in the particular important link also has two parallel transmission, one of the spare, use a multi conveyor in series.

输送机配件托辊是皮带输送机当中一种较为简单却又占有大比例的重要输送零件，托辊在皮带输送机当中的主要作用支撑输送带和物料的重量。

Conveyor accessories roller is an important part of the belt conveyer which is relatively simple but occupies a large proportion. The main function of the roller in the belt conveyer supports the weight of the conveyer belt and the material.

滚筒输送线是自动化输送设备中非常重要的产品，是工业企业生产中用来进行水平方向输送生产物料，垂直方向输送生产物料和倾斜方向输送生产物料。

The roller conveyer line is a very important product in the automatic conveying equipment. It is used in the production of industrial enterprises to carry the production material in the horizontal direction, conveying the production material in the vertical direction and conveying the production material in the inclined direction.
