简体中文 Hey, are you fretting about that pile of roller conveyor lines in your factory? Single sprocket or double sprocket? Stainless steel or rubber covered? Do not panic, today we will use the vernacular to break this matter to understand - read this, you can become half a connoisseur!
First, the transmission mode: single sprocket vs double sprocket, in the end where the difference?
The central question: Why do I have to use a double sprocket for heavy cargo?
Simply put, a double sprocket is like two people carrying a sedan chair, more stable than one! Take a look at the hardcore comparison:
| comparison term | Single sprocket system | Double sprocket system |
|---|---|---|
| transmission force | Suitable for light loads (≤500kg) | Heavy load carriers (>1 tonne) |
| Conveying distance | Short range (≤ 6 metres) | Long distance king (>8 metres) |
| static (in a signal) | (onom.) clatter of chains | It's quiet, but the chain still sounds. |
| turning ability | Flexible and suitable for curves | Straightaway specialists. Turns have to be made with tapered rollers. |
personal spiteDon't buy into the "single sprocket saves money" nonsense! If you use a single sprocket for heavy-duty scenarios, you can buy two sets of double sprockets for the same amount of money you'd spend on repairing the machine!
Second, how to choose the material? Look at the environment under the dish!
Soul question: is stainless steel superior to galvanised?
Re! Choosing a material has to be like picking a dress - it's all for naught if the occasion isn't right!
- Galvanised rollers: Cheap and resistant.Preferred for dry warehouse environments! But a wet shop rusts to a pockmarked face after six months of use.
- Stainless steel (304/316L):.Food factory, chemical plant motherly configurationIt's acid-resistant and corrosion-resistant! But it's expensive! It's pure money for ordinary warehouses.
- Rubber-coated rollers:.Climbing anti-slip device! But watch out:
- Don't use the food line! Gum crumbs mixed into a milk tea cup is the end of the line;
- Dust-free workshop detour, fall powder fall to doubt life.
experience acquired through blood and tears: Lithium Battery WorkshopProhibition of galvanised rolls(Zinc ion contaminated batteries)! Directly on stainless steel or chrome plated!
Third, the three major pits of layout design, 90% novice stepped on!
1. Roller length = width of goods + 50mm?
- straight line segment: 50~100mm wider than the cargo is enough;
- cornering section:.It must be widened!Formula:
Minimum roll length = cargo diagonal + safety allowance.
📌case (law): 1 metre long box turn, roller at least 1.2 metres! Otherwise jam the corner and hit the wall in minutes.
2. Lazy roller spacing? Waiting to roll over!
Golden Rule: Spacing ≤ 1/3 of the length of the goods!
- For example, a 2-metre-long pallet.Spacing up to 66cmOtherwise, the centre will be overhanging and the waist will collapse;
- Double Sprocket OCD Warning: The spacing must meet
T=n×chain pitch/2(n is an integer), otherwise the chain will not fit!
3. Misplaced motor? The effort was wasted!
- single chain pulley: The motor is mounted on the tail and won't pull;
- Double sprocket:.The motor must be mounted in the middle!Uniform power does not come off the chain!
Fourth, the installation and maintenance: the secret of saving the heart to give away
What's the best way to install it?
- Spring loaded: The powerless line is quick to dismantle, butDon't ever use power lines.! Derailed at the first tremor;
- Female thread locking type:.Double sprocket as standard! The bolt is steady as an old dog when it's screwed on.
Maintenance lightning guide
- Must do every month: Feel the chain tension (sagging ≤ 2cm), listen to the bearing noise (clatter = time to change);
- The big move of the year: Clear chain sludge!Washing with paraffin is 10 times better than lubricating oil.!
V. A personal view: don't just focus on the immediate future when selecting a model!
Many bosses key material to save money, the result? Stainless steel to galvanised to save 50,000, the second year of maintenance to spend 80,000!The real value for money is "10 years without major repairs.".
Others say "single sprocket first, then upgrade if it's not enough" - pure fluff! Conveyor LineThe foundation racks are all done to the initial design, late remodelling burns more money than new construction. Remember that.Spend an extra week in planning and save 10 years in commissioning!
Lastly, I would like to say one thing: Conveyor line is the bloodline, selection is the lifeblood. Match the material according to the scene, set the transmission according to the load, calculate the layout based on the data -Your line, it's time to go steady as a rock!
