简体中文 Guess why some of those efficient conveyor belts in factories are lightning fast and some can stop on a dime? Here's the key.Speed Chain Conveyor LineThe four major types! Today, let's talk about the four categories: light duty, heavy duty, adjustable speed, and accumulator, so you'll understand how to choose after listening!
🛠️First, light load type: electronic small parts handling "dexterity fast hand"
core principle: By engineering plastic roller friction drive, the chain goes at a constant speed, but the work plate can run out of2-3 times faster(e.g. 1m/s for chains, 2-3m/s for workpieces).
Why is it fast?Wheel diameter > roller diameter, physical leverage to amplify the speed - simply put, "small wheels with big wheels, the more you run, the more energy".
Applicable Scenarios::
- electronics assembly: Mobile phone parts, chips and other small and light parts (single point ≤ 500kg)
- Appliance assembly: Remote control, small motor assembly line
- cutting edge: low noise, anti-static, cost-friendly (nylon material saves electricity and is cheap)
give me a chestnutA mobile phone factory with a light load times the speed chain, the speed of the workpiece board to 3m / s, an hour can pass 2000 motherboards, doubling the efficiency is not afraid of static electricity damage.
🏋️♂️Second, heavy-duty type: automotive parts of the "steel tough guy"
core principle: All-steel chain + thickened rollers, single-point carrying4000kg(≈ two baby elephants!) , the speed is pressed to 8-10m/min to prevent jerks.
Key Design: Hardened steel chains are abrasion and pressure resistant, with large diameter rollers to disperse the pressure.
Applicable Scenarios::
- automobile manufacturing: Engine and gearbox handling (case in point: a factory transported a 3-tonne cylinder block with zero failures for 8 years)
- Heavy machinery: Machine tool bases, large sheet metal conveyors
- cutting edge: Impact resistance, high temperature resistance (150 ℃ spray paint shop run as usual)
Watch out for pits.: Overloaded 30% failure rate soared 50%! Heavy load must be equipped with variable frequency motor speed stabilisation.
⚡Third, adjustable speed type: flexible production of the "Transformer"
core principle:.Servo motor + inverterReal-time adjustment of roller angle and seamless switching of speed from 1m/s to 4m/s.
Where's the flexibility?: One line handles different sized products at the same time, such as shipping laptops in the morning and switching to appliance boxes in the afternoon.
Applicable Scenarios::
- Mixed flow production line: E-bike battery + frame mix
- Seasonal products: Holiday gift boxes, customised small batches
- cutting edge: No downtime for production change, energy consumption reduced by 40% (vs. fixed speed)
real effectA new energy battery factory with adjustable speed chain, switching product speed as long as 10 seconds, capacity utilisation rate rushed to 90%.
⏸️IV. Accumulation: the "smart buffer zone" of the assembly line
core principle:.Pneumatic stopperWhen the plate is lifted, the rollers are suspended and stopped, and the chain runs as usual - just like "applying the brakes without switching off".
miraculous operation: When a work station is jammed, the workpieces behind it are automatically bypassed without blocking the traffic.
Applicable Scenarios::
- quality control station: Mobile phone screen pause detection (±0.05mm precision positioning)
- Manual assembly section: Car seat installation, circuit board plug-in
- cutting edge: Reduced wear and tear on emergency stops, 3 times longer chain life
Typical Layout: U-shaped line + multi-station accumulation, electronics factory 60 workpiece board cycle run, temporary storage 30% materials do not pile up the ground.
💎Personal opinion: do not follow the trend of selection, matching is king
After ten years of automation, I've seen too many factories step on potholes-Light-duty chains carry heavy loads hard(Resulting in a chipped roller).Heavy Duty Chain Running E-Line(Electricity costs 50% more) ...... Actually, right, picking a multiplier chain stares at three things:
- carrying capacityOver 500kg, put on the steel chain honestly, don't save the material money;
- beats: Changing products every day? Close your eyes and choose adjustable speed! Fixed on the assembly line? Accumulation type is more stable;
- matrix: Hot and humid environments? Stainless steel chains are expensive but save maintenance.
Future trends to look at.Adjustable speed + accumulationCombination will be the mainstream (such as new energy battery line), after all, flexible production is the lifeblood of manufacturing. However, small and medium-sized factories should not be anxious, ordinary light load line optimised, the efficiency of the same crushed human handling - remember, the right far more important than the high-end!
