简体中文 Hey, mate! Is your factory still manually humming and hawing to move boxes? 🤔 Is your back breaking after moving a load of goods, and you're still madly inefficient? Don't panic! Let's talk about it today!Customised in-line roller conveyor linesThe doorway - the size of how to measure, load-bearing how to calculate, how to choose the material, read it to ensure that you from a small white into an insider!
🔧 I. Calculation of core parameters: size + load bearing is the lifeblood!
Customised roller lines aren't clothes shopping.Size difference of one centimetreAll of them can be carded cargo flips! Remember these 3 golden formulas:
- Roller length= Cargo width + 50mm 👉 (e.g. if the box is 400mm wide, choose 450mm for the drum)
- Roller pitch≤ 1/3 of the length of the goods 👉 (1 metre long goods, do not exceed 330mm spacing, or you will fall out of the pit!)
- Single drum load= Total cargo weight ÷ Number of contact rollers 👉 (For a 500kg load, assuming 5 rollers are stressed, each one has to carry 100kg!)
📌lesson learnt through blood and tears: The owner of a factory did not calculate the load-bearing, the result is that the drum bending deformation, stop production for three days and lost 200,000 yuan!
Influence of material on load bearing (must see comparison table)
| Roller material | Applicable load-bearing range | Cost per metre | Applicable Scenarios |
|---|---|---|---|
| Carbon steel galvanised | 50-300kg | ¥200-300 | Warehouse plain cartons |
| Stainless steel 304 | 100-500kg | ¥600-800 | Food factories, chemical plants 🌫️ |
| Thickened steel tube | 300-2000kg | ¥400-600 | Automotive parts, metal goods |
| aluminium | ≤100kg | ¥500-700 | Light goods for electronics workshop |
You taste it. You taste it.: Want to save money with carbon steel? If the workshop is humid, half a year of rust wearing awaits you! Stainless steel is expensive but for good reason - it's built to last!
🛠️ Second, the choice of materials: do not be led by the business!
The most confusing thing for newbies is the material! Take my advice.Look at the environment to choose the material, more important than the price::
- general warehouse👉 Carbon steel galvanised enough (surface sprayed to prevent rust, low cost)
- Seafood/Freezer❄️ 👉 Must be stainless steel! Ordinary steel is brittle at low temperatures and shatters on impact
- chemical plant☣️ 👉 Stainless steel + rubber-coated rollers, corrosion-resistant and also anti-static
- Lithium battery workshop🔋 👉 No galvanised rollers! Zinc ions contaminate batteries, use pure stainless steel!
💡Exclusive data: Food factory with the wrong carbon steel roller, rust contaminated goods were fined 500,000 - material money can not save ah!
⚡ III. Drivetrain configuration: wrong choice of power = for nothing!
What about the motor? What's the transmission?Remember these two mnemonics:
- O tape for light cargo short👉 Quiet and cheap (but don't go over 30kg/unit or you'll slip!)
- Double sprockets for heavy loads and long lines👉 Carry the build! (2000kg moulds depend on it)
- Motorised pulleys for precision sorting👉 Variable frequency control ±1mm error, expensive but accurate!
Power programme cost comparison (10 m line reference)
| Driving method | (manufacturing, production etc) costs | maintenance difficulty | Applicable Scenarios |
|---|---|---|---|
| Non-Powered Roller Drives | ¥10,000 | ⭐ | Manual push of light goods |
| O-Belt Drive | ¥25,000 | ⭐⭐⭐⭐⭐⭐⭐ | E-commerce parcel sorting 📦 |
| chain drive | ¥38,000 | ⭐⭐⭐⭐⭐⭐⭐⭐ | Tyre/Metal Parts Conveying |
| drum motor | ¥60,000+ | ⭐⭐⭐⭐⭐⭐⭐ | Automated three-dimensional warehouse |
Let's be honest.: Don't pick the wrong power to save 20k - it's more expensive to retrofit later!
🧩 Fourth, a guide to avoiding the pit: 3 secrets manufacturers will never tell you
- Installation methods hide mines💥: spring-loaded press-in rollers are cheap, but they can come off the shaft with a lot of vibration! Heavy loads must use through-axle pin hole type
- Gum wrapping set is deep👉 Natural rubber is cheap but not oil resistant, auto parts factories have to use polyurethane rubber (twice as expensive but lasts 3 years longer!)
- environmental trap🌧️ 👉 If you use ordinary bearings in a wet workshop in the south, they will squeak in three months! Choose IP54 waterproof bearings!
📢case (law): An e-commerce warehouse didn't do moisture-proof treatment to save money, and as a result, the bearings rusted to death during the rainy season, and the sorting was paralysed for 48 hours!
💎 Exclusive insights: the underlying logic of customising for success
Roller lines are not standard! Based on the 200+ projects I've handled, the aftermarket problems with the 80% have beenMismatch of front-end parameters.. A common mistake newbies make:
- Only look at the total price, ignoring the difference in material costs (stainless steel is 3 times more expensive than carbon steel but lasts 8 years longer)
- Load capacity is dead, no safety margin (standard 300kg drum, long-term use is recommended ≤250kg).
- Ignore the workshop temperature 🌡️ (-15℃ environment with ordinary grease? It freezes directly to iron!)
Finally dump a hardcore statistic.Roller lines designed according to national standards, the failure rate is lower than the wild card solution 67% - don't be soft when it's time to pick the details!
(Knocking on the door) Customising a roller line is like taking a suit--A hair's breadth difference in size can lead to a thousand miles difference in effect.. Save this article and dislike the manufacturers one by one when customising and ask them to make sure you don't fall for it! 🚀
