> **Kokkuvõte**
> Small copper tube coils can be sealed in centre-folded POF film on an L-bar sealer, then shrunk tight in a heat tunnel. Our equivalent solution packs **10–25 packs per minute**, depending on size. The key check is the sealing window: a coil up to 350 mm across and 125 mm high, with width + height up to 400 mm. Larger coils need a side sealer or an orbital coil wrapper.

Mida protsess teeb
Videol on näha ükshaaval pakitud väikesed, lamedad vasktorudest mähised:
1. **Infeed.** The coil lies flat on the infeed conveyor.
2. **Film and seal.** Centre-folded film opens over a triangular film frame and wraps the coil. The L-shaped knife seals the open side and the end.
3. **Shrink.** A roller conveyor carries the pack through the heat tunnel, where the film tightens around the coil.
4. **Outfeed.** The wrapped coil leaves on the roller conveyor.
Kahanev kile hoiab tolmu ja niiskuse vasest eemal ning hoiab mähise keerud koos. Meie samaväärne lahendus selle töö jaoks on L-varda kahandav masin FP-400LA tunneliga SH-450C.
Mähise kontrollimine tihendusakna vastu
Lame mähis on ümmargune, seega on selle pikkus ja laius mõlemad välisläbimõõt (OD). Kontrollige nelja piirangut:
| Limit | L-bar sealer FP-400LA |
|---|---|
| Sealing height | 125 mm or less |
| Packing width | 350 mm or less |
| Width + height | 400 mm or less |
| Length + height | 480 mm or less |
Kaks näidet, mõlemad illustreerivad:
- **Coil OD 300 mm, height 60 mm.** Width 300 mm and height 60 mm are inside the limits. Width + height = 360 mm and length + height = 360 mm. It fits.
- **Coil OD 380 mm, height 60 mm.** The width of 380 mm is over 350 mm. It does not fit the L-bar sealer.
tehnilised nõuded
| Parameeter | Väärtus |
|---|---|
| Sealing type | L-bar sealing |
| Packing capacity | 10–25 packs per minute (depends on product size) |
| Film | centre-folded POF film |
| Max film roll | 530 mm wide, 280 mm outer diameter |
| Sealer power | 1.5 kW (sealer only) |
| Working height | 780–850 mm |
| Sealer weight | 390 kg |
Kiirusel 10–25 pakki minutis võtab ühe mähise valmistamine aega 2.4–6 sekundit. Tegeliku kiiruse kinnitame teie mähise suuruse ja tunneli kiiruse põhjal.
1.5 kW võimsus hõlmab hermeetikut. Kahanev tunnel on eraldi, suurem küttekoormus ja me toome selle võimsuse teie pakkumises välja, et saaksite varustust planeerida.
Kui mähis on liiga suur
Kui mähis on L-riba aknast suurem, liigume teise masina juurde:
- **Side sealer MO-900.** It takes products with width + height between 400 and 900 mm, and up to 300 mm sealing height. The 380 mm OD coil above, with width + height = 440 mm, fits here. The tunnel needs up to 28 kW.
- **Copper tube coil wrapper.** For large coils of 600–1,200 mm OD and 50–300 kg, we wrap through the coil eye with stretch film, paper or woven material instead of shrinking. The overlap is adjustable from 20% to 90%.
Kile ja tihendamine
- **Knife.** An aluminium alloy sealing knife with DuPont Teflon coating resists heat and does not stick to film.
- **Temperature.** An Omron digital temperature controller sets the sealing temperature accurately.
- **Detection.** Photocells detect thin and small products, so low coils are sealed reliably.
- **Feeding.** Automatic film feeding with a punch device, and automatic waste winding.
- **Line use.** The machine can run unmanned in a production line.
Kommunaalteenused ja ohutus
| Kasulikkus | Nõue |
|---|---|
| Power | 380 V, 50–60 Hz, 3 phase |
| Air | 0.5 MPa (5 bar) or less |
Sulgemisnoal on automaatne kaitse ja alarm, mis parandab operaatori ohutust. Kohaldatavad standardid sõltuvad sihtturust. CE-turgude puhul kehtestab ISO 12100 riskihindamise meetodi ja EN 415-10 pakkimismasinate üldised nõuded.
Vaskmähise kahaneva pakendi valiku kontroll-leht
- [ ] Coil OD, ID and height, smallest and largest.
- [ ] Coil weight.
- [ ] Coils per minute needed.
- [ ] Film: centre-folded POF, roll width and diameter.
- [ ] Inline with the coiler, or a standalone station.
- [ ] Power and compressed air at the station.
Inseneri KKK
Q: What coil size fits the L-bar sealer?
A: Up to 350 mm wide and 125 mm high, with width + height up to 400 mm and length + height up to 480 mm.
Q: How fast is the machine?
A: 10–25 packs per minute, depending on product size.
Q: What if my coil is 380 mm across?
A: It is over the 350 mm packing width. The side sealer MO-900 takes it, since width + height falls in its 400–900 mm window.
Q: What film does it use?
A: Centre-folded POF film, on rolls up to 530 mm wide and 280 mm in diameter.
Q: How do you pack large copper coils?
A: Coils of 600–1,200 mm OD go on our copper tube coil wrapper, which wraps through the eye with an overlap from 20% to 90%.
