同時(shí)雙層滾筒輸送機(jī)采用一臺(tái)電機(jī)進(jìn)行驅(qū)動(dòng)，和獨(dú)立的兩臺(tái)滾筒線相比，節(jié)約了一臺(tái)電機(jī)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(shè)計(jì)時(shí)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.

皮帶輸送機(jī)的結(jié)構(gòu)參數(shù)的優(yōu)化方法皮帶輸送機(jī)的結(jié)構(gòu)雖然受到了種種工況的限制，而輸送機(jī)的工作狀態(tài)是處于滿載正常運(yùn)行的狀態(tài)，在常規(guī)設(shè)計(jì)計(jì)算方法完成后，可以進(jìn)行采用離散變量?jī)?yōu)化的網(wǎng)絡(luò)法，對(duì)帶式輸送機(jī)參數(shù)進(jìn)行優(yōu)化設(shè)計(jì) 。

Optimization of the structural parameters of belt conveyer, the structure of belt conveyer is restricted by various working conditi, and the working state of the conveyor is in a state of full load. After the completion of the conventional design calculation method, the network method of discrete variable optimization can be used to optimize the parameters of the belt conveyor. Chemical design.
