Logistics stuck around the corner? Tens of thousands of parcels a day crowded sorting centre? Don't worry, let's talk about it today.How to choose the type of turning roller conveyor lineOnly then can you make the goods silky smooth steering! Choose the right equipment, efficiency increase of 30% is not a dream, choose the wrong? Minute jamming downtime to show you
I. Turning Principle: The "Speed Difference Magic" of Conical Rollers
Why do I have to use a conical roller?Simply put, the inner circle is slow and the outer circle is fast.!
- Taper design: Common 3.6° taper angle (52.9mm on small end vs 56mm on large end), allowing the outside line speed to be 15%-30% faster than the inside.
- centrifugal force balance: The cargo is thrown outward by centrifugal force when turning, and the high speed on the outside counteracts this force.
- The Golden Formula: Turning radius R = (diameter of small end of cone roller + clearance)/(2 x tanθ/2)
give me a chestnut: Conveying 800mm long carton, minimum turning radius = 800 x 1.2 + 100 =820mm(Direct selection of standard 900mm size)
Second, the selection of the five iron laws (white to avoid the pit guide)
1.Don't pick a turning radius.
- Formula.R ≥ 1.2 x cargo length
- Standard value: 600/900/1200mm in three grades (1500mm or more for extra-long goods)
- lesson learnt through blood and tearsAn auto parts factory used a 600mm radius to transport 1 metre of steel pipe, and got stuck as a "snake".
2.Material Determines Lifespan
| material (that sth is made of) | Applicable Scenarios | dividing point |
|---|---|---|
| stainless steels | Food factory/pharmacy (corrosion resistant) | Two times more expensive than carbon steel |
| Rubber-coated rollers | E-commerce courier (noise-reducing and non-slip) | Dropping powder! Can't use it in a clean room. |
| galvanised steel | general warehouse | Rust in half a year in a humid environment |
3.Driving method looks at the cost
- chain drive: ¥800/m, suitable for short lines within 10 metres
- drum motor: ¥2000/m, long line failure rate straight down 70%
trade slang: Over 15 metres of conveyor line, don't use a chain drive!
4.Load Rating Selection Structure
- Light load (<50kg/m) → Nylon cone roller (wall thickness 3mm)
- Heavy load (>200kg/m) → steel cone roller + auxiliary support wheel
5.Environmental suitability is the bottom line
- Wet shop: Select IP67 protection class
- Cryogenic cold storage: plastic parts prohibited (risk of brittle cracking)
Third, 5 major industries practical analysis (with transformation cases)
▶ E-commerce logistics: how to play with 100,000 pieces per day?
sore point: Double Eleven Blowout, Sorting Error Rate 5%
programme: 900mm bend line + rubber-coated taper sleeve
- Result: Site saved 251 TP3T and error rate reduced to 0.81 TP3T
dodge a pit: Never save on turning radius! A warehouse uses a 600mm radius to cause boxes to "stack up"
▶ Automotive Manufacturing: How to Choose the King of Heavy Duty?
sore point: 200kg Engine Tray Turning Shake
programme: 1200mm steel cone roller + double chain drive
- Addition of dynamic support beams (spacing ≤ 800mm)
- Result: Welding line beat speed up by 22 seconds/unit.
▶ Food processing: how do you pass the hygiene standards?
sore point: FDA inspection failed
programme: Stainless steel rollers + seamless welding
- Slope ≤3° to prevent soup spillage
- Case: A quick-frozen factory passed GMP certification after renovation
▶ Pharmaceutical workshop: 300,000 clean area how to do?
Deadly details.: Use rubber-coated rollers? Wait for the colonisation overload!
programme: All stainless steel + self-lubricating bearings
- With magnetic deskew (anti-drug cartridge deflection)
▶ Electronics factory: precision circuit boards afraid of vibration?
flirty trick: PU rubber sleeve roller + speed limit 0.5m/s
- Vibration damping improved by 60% and scrap rate reduced from 3% to 0.5%.
IV. The future is here: technology trends in 2025
- AI Visual Correction: Real-time detection of offset >5mm automatic speed regulation
- Graphene self-lubricating: 20,000 hours maintenance-free (currently only 5,000 hours)
- Modular assembly: Build a conveyor line like Lego (save 50% installation fee)
Personal opinion time: don't be fooled by fancy features!Small and medium-sized factories prioritise three things to look at-Turning radius matching degree, material resistance, maintenance is convenient. After all, what we want isNo downtime, no jamming, no burnoutThe three best devices!
