Intelligent factory logistics upgrading: PVC roller conveyor line selection practical guide

One.Scenario pain point: Why does your conveyor line always go wrong?​

  • ​Case background: Frequent skidding and excessive noise problems occurred in a food factory's boxed goods conveyor, and some rollers rusted and corroded during the rainy season.
  • ​Core pain points::
    • ​Material Misselection: Ordinary carbon steel rollers are prone to rust and corrosion in humid environments, increasing maintenance costs;
    • ​Layout flaws: The roller spacing between the straight section and the turn was not optimised for the cargo dimensions, resulting in box wobbling;
    • ​Insufficient friction: Smooth PVC drum surfaces slip on sloping sections, affecting efficiency.

Two.Material selection: 4 types of drum material scene adaptation list​

1.PVC Roller(cost-orientated)

  • ​Applicable Scenarios: Antistatic areas in electronic workshops, food packaging lines (food-grade certification required)
  • ​cutting edgeNoise <65dB, lighter than steel 50%, weak acid and alkali resistant
  • ​Achilles' heel: Load limit is only 50kg/pc, not suitable for heavy loads (e.g. automotive parts).

2.Stainless Steel Roller(preferred for harsh environments)

  • ​take: Aquatic processing area (salt spray resistant), chemical workshop (acid and alkali resistant)
  • ​Key to Selection::
    • SUS 316 (chlorine ion resistant) for seafood transport, SUS 304 for conventional;
    • Costs 40% more than carbon steel, but lasts 3 times longer.

3.Rubber-coated/sleeved rollers(anti-skid friction programme)

typology coefficient of friction Applicable Scenarios taboo scene
​PVC rubber sleeve​ 0.3-0.4 Straight-line conveyor for boxed goods Oily environment (slippery)
​PU rubber sleeve​ 0.5-0.6 Slope climbing (angle ≤ 15°) High temperature >50℃ environment

Three.Layout Design: 3 Parameters Precision Calculation Method​

1.Roller length formula​

​​W = A + (50~100)mm​(A = width of cargo)

  • ​case (law): Conveying 600mm wide cartons, selecting roller lengths of 650-700mm;
  • ​contraindication (medicine): Roller length < cargo width 80% will result in overhanging box edges.

2.Golden Rule of Roller Pitch​

​​P ≤ 1/3L​(L = length of cargo)

  • ​Precision Scene: Flexibag packaging requires​P=1/5L​(If L=1m then spacing ≤200mm) Anti-denting;
  • ​overloaded scenario: Palletised goods need to be checked for single roll loads≤Rated load 80%(Example: Medium 50mm PVC rollers with a load limit of 25kg).

3.Turning Section Design Pothole Avoidance Guidelines​

  • ​taper​：标准3.6°，转弯半径790/840mm；
  • ​​关键校验​​：锥辊管径延长线必须指向转弯圆心，否则货物偏移。

Four.​行业定制方案：匹配场景的选型模板​​

1.​食品工厂方案​​

  • ​material (that sth is made of)​：SUS 304不锈钢+食品级PU胶套（FDA认证）；
  • ​opening (chess jargon)​：斜坡段坡度≤3%，滚筒间距=箱长1/4（防倾倒）。

2.E-commerce sorting centre programme​

  • ​Power Configuration​：多楔带传动滚筒（静音+传动力矩3倍于O带）；
  • ​special needs​：积放式滚筒实现包裹暂存，缓冲峰值流量。

3.​重工业厂区方案​​

  • ​Material Substitution​：PVC滚筒 ​​→ 碳钢镀锌滚筒​​（承载提升至150kg/支）；
  • ​​防护设计​​：包胶滚筒防金属件划伤，辊间距压缩至1/5L抗冲击。

Five.​成本陷阱：这些钱绝对不能省！​​

  1. ​environmental adaptation::
    • 潮湿环境选镀硬铬滚筒（成本+15%，寿命×2）；
    • -25℃低温禁用PVC（脆化），改用全钢制。
  2. ​transmission method::
    • 高负载场景链轮传动（成本低但噪音大），洁净车间用多楔带（静音贵30%）；
  3. ​​安装方式​::
    • 动力辊筒禁用弹簧压入式（易脱位），必用内螺纹固定。

​Final Recommendations​：提交需求时必填4项——货物尺寸/重量、环境温湿度、坡度要求、日均工作时长。厂家依此匹配材质与布局，故障率直降70%！
