Type and spacing of the roller

托辊是用于支承输送带及输送带上所承载的物料，保证输送带稳定运行的装置。

The idler is a device for supporting the conveyer belt and the material carried on the conveyer belt and ensuring the stable operation of the conveyor belt.

一、托辊种类

Type 1. Type of roller

a.槽形托辊：用于承载分支输送散状物料。

A. trough idler: used for carrying branches to convey bulk materials.

b.平行托辊：平行上托辊，用于承载分支输送成件物品，平行下托辊用于回程分支支撑输送带。

B. parallel rollers: parallel upper rollers are used for carrying branches to form articles, and parallel lower supporting rollers are used for supporting branches of backhaul branches.

c.调心托辊：用于调整输送带跑偏，防止蛇行，保证输送带稳定运行。前倾式槽形托辊也起调心、对中作用。

C. aligning idler: used to adjust the conveyor belt deviation, prevent snakes, ensure the stable operation of the conveyor belt. The tilting trough idler also plays the role of aligning and aligning.

d.缓冲托辊：安装在输送机受料段聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 的下方，减小输送带所受的冲击，延长输送带使用寿命。

D. buffer rollers are installed below the receiving section of the conveyor to reduce the impact of the conveyor belt and extend the service life of the conveyor belt.

e.回程托辊：用于下分支支撑输送带，有平行、V形、反V形几种，V形与反V形辊能降低输送带跑偏的可能性。当V形和反V形两种型式配套使用，形成菱形断面，能更有效地防止输送带跑偏。

E. backhaul idler: for the lower branch supporting conveyor belt, there are several parallel, V and reverse V shape, V and anti V roller can reduce the possibility of deviation. When the two forms of V and reverse V are used together to form a diamond section, the deviation of the conveyor belt can be prevented more effectively.

此外，还有梳形托辊和螺旋托辊，能清除输送带上的粘料，保持带面清沽。

In addition, comb shaped idlers and spiral idlers can remove sticky materials on the conveyor belt and keep the noodles clean.
