简体中文 Have you ever wondered why those piles of goods in factories can "walk" by themselves? Mobile phone parts, express parcels, and even bags of cement, how can they obediently move forward in a queue? To put it bluntly, behind80% of the time, it's the belt conveyor that's doing the work.This thing is like the "veins" of a factory! This thing is like the "blood vessels" of the factory, and today we will break it down and talk about its ways.
First, the first whole understand: belt conveyor line in the end is a what?
Simply put, it's a moving rubber track.. Once the motor is on, the belt turns round and the stuff you put on it is carried along. It is not a small conveyor belt like a supermarket checkout counter, but a big one that can carry several tonnes of goods and run for hundreds of metres! These are the main components:
- leather beltRubber, PVC, canvas, and special "food grade" belts for food factories.
- platen: Two large cylinders at the head and tail, one for pulling (drive drum) and one for tensing (reversing drum).
- rolls: A row of small wheels underneath to prevent the belt from collapsing, flat or slotted
- Motor + reducerPowering the whole system, it's the "heart".
And guess what? This structure existed over a hundred years ago - the British came up with the first one in 1868, and now even the Mars rovers use a similar principle to transport soil samples!
Second, how does it work? Physics teachers are straight from the inside!
Imagine you're standing on a treadmill: the belt turns backwards and you run forwards. Belt Conveyor LineSame principle, but smarter.! The core depends on the two forces:
- friction: The motor makes the drive pulley turn, the pulley and the belt are tightly attached, and when they rub together, they run with the belt.
- strain: Tail tensioner (weights or screws) to straighten the belt and prevent slippage.
Here's the key: why doesn't anything fall off the belt?
- Flat belts carry boxes and bags no problem.
- Carrying sand and coal briquettes? Change it.Grooved Roller! Concave the belt into a U-shape, the material is naturally gathered in the middle.
- Afraid of splashing material? Add to the beltFendering SkirtIt's like a fence.
Three, where is this thing popping up? All over the place!
Honestly.You've seen it all around you in 90% industrial.::
| sector | What kind of work? | special requirement |
|---|---|---|
| mine quarry | Carrying thousands of tonnes of ore in an hour. | The belt should be resistant to smashing! Add a tear-resistant layer |
| Express Logistics Centre | Sorting your double eleven parcels in the middle of the night. | With code reader, automatic route identification |
| food factory | Transferring biscuits, filling drinks, and cooling cans. | Must use food grade non-toxic belts |
| Automotive assembly line | Engines, doors lined up for workers to screw in | Precise stopping with less than 1cm error |
| waste treatment plant | Separate waste for incineration or landfill. | Anti-corrosion! Stinky water and rotten vegetables don't hurt the belt |
Even the mountains of furniture in IKEA's warehouse are climbed up and down by it-Tilt angle up to 30 degreesIf you bring a baffle, it won't slip down!
Why do factories have to use it? The advantages are on the table!
Save people, save money, save time, and the three best tricks are taken to death.
- Efficiency Monster24 hours a day, 5 times faster than manual handling.
- killer of the electric bill:: Carrying a tonne of cargo for one kilometre uses less than half a kilowatt-hour of electricity (except for heavy-duty miners).
- not picky about food: from small chips to large car tyres, flat walking, climbing and turning can be arranged!
- have a low voice: Much quieter than a chain conveyor, no yelling in the shop!
A chestnut: after a cement plant switched to a belt line, theDirect labour cost reduction of 60%It also avoids workers from lifting heavy objects and flashing their backs.
Fifth, the disadvantages are not to be avoided! These pitfalls must be guarded against
As the old saying goes, don't take up porcelain work without a diamond drill. BeltlineThe three biggest headaches::
- diverge: The belt is crooked in an S-shape, and the material falls down with a crash.
What's the deal? Level the drum! Or installAnti-skew rollersautomatic deskew - skid: The motor whirrs and the belt lies flat in place.
What's the deal? Tighten the tensioner a little! Or feed the rollersCeramic paste to increase friction - wear and tearGravel scratching, high temperature baking, the belt becomes "brittle" after a long time.
What's the deal? Steel wire core belt for coal mine, high temperature plant for heat-resistant rubber.Saving a little money to repair the machine instead of blood loss
Plus ah, itYou can't catch your own material.--have to be put upwards by hand or machine. The route is also fixed. Want to reroute it?We'll have to dismantle it and reinstall it..
Six, the newbie must ask: 5 soul torture live answer!
Q1: What is the longest a belt line can stretch?
A: Don't exceed 60 metres for a single strip, otherwise it's easy to get loose! Butsolitaire (puzzle)--I've seen harbours pick up out 15km to carry coal, like a glutton for punishment.
Q2: How fast can I go?
A: Small parts transfer whooshing in electronics factories.Up to 30 metres per minute; the Steadies, which carry large ores, are just 10 metres per minute.
Q3: Is the repair a shutdown?
A: Modular design saves the day! Changing section beltsOne hour., without having to be paralysed on all fronts.
Q4: What about cleaning? Food factory stained with oil is not finished?
A: Early preparationAutomatic scraper + ultrasonic cleaning! The assembly line at the meat plant is bathed and sterilised daily.
Q5: Will we be eliminated by robots in the future?
A: Don't worry!Magnetic Levitation Conveyor LineIt's more advanced, but 10 times more expensive! Regular factory or belt line really smells good.
Editor's view
After ten years in the factory, I dare sayBelt conveyors are the "old bulls" of industry.-No AGV carts are cool, not as precise as magnetic levitation, but as far asIt's durable and saves money., it still carries the belt. Think about that the next time you open your delivery, your parcel may have just travelled on the beltline! Fancy technology again.Solving real problems is the way to goYou're right.
