為使鑄坯平穩(wěn)迅速地運送，有時將這個區(qū)的輥道設計成可升降的。輥道按驅(qū)動方式可分為集中傳動輥道和單獨傳動輥道兩種。集中傳動輥道由一臺電機帶動一組輥子，通過電機一減速機一鏈輪傳動，或者通過電機一減速機～長軸一傘齒輪傳動方式傳動。

In order to deliver the billet smoothly and quickly, the roller table in this area is sometimes designed to be lifted and lifted. The roller table can be divided into two types: the  drive roller and the separate drive roller. The  driven roller table is driven by a motor to a set of rollers, driven by a motor, a reducer or a sprocket, or through a motor, a reducer, a long shaft and a bevel gear transmission mode.

同時雙層滾筒輸送機采用一臺電機進行驅(qū)動，和獨立的兩臺滾筒線相比，節(jié)約了一臺電機和電控裝置的開支，這樣為企業(yè)節(jié)約了成本，但是要注意在設計時要注意兩層滾筒線之間的高度要高于物料的高度。

At the same time, a double layer roller conveyor is driven by a motor. Compared with the two independent  lines, it saves the expenses of an electric motor and electronic  device. This saves the cost for the enterprise, but attention should be paid to the height of the two layers of the roller line when the design is higher than the material.

包膠滾筒安裝方便

包膠滾筒安裝起來特別的方便，不需要安裝好在送過去，現(xiàn)場進行安裝就可以了，滾筒也是不需要拆卸的，這樣是非常方便的，你只需要付錢、收獲、等著用就可以了，其他的都有專業(yè)的人士來干。

Easy installation of rubber drum

Package rubber drum installation is especially convenient, do not need to install in the past, the site can be installed, the cylinder is not required to be disassembled, so it is very convenient, you only need to pay, harvest, and other use, and other professional people to do.

皮帶輸送機的常規(guī)設計方法所存在的問題帶式輸送機常規(guī)設計方法實際上是一種安全或是偏于保守的設計方法。例如。選用的輸送帶安全系數(shù)、運行阻力系數(shù)偏大，從而造成選用的電動機功率過大，帶寬過寬或是抗拉強度要求較高。

The conventional design method of belt conveyor is a safe or cervative design method. For example. The safety factor and the running resistance coefficient of the selected conveyor belt are too large, resulting in excessive power selection, wide bandwidth or high tensile strength.
