**执行摘要**
> We pack a carpet roll by forming a continuous film tube around it, then sending that sleeve through an enclosed heat tunnel. The film shrinks onto the body and the ends, so the pack leaves closed. The clip is 65 s and follows one roll from the green belt to the finished pack. We size the sleeve from roll OD and length, not from a chamber-sealer film chart.

视频片段按顺序展示了以下内容
我们建造了这条短生产线，用于输送卷状地毯和毛毯。操作员将一卷地毯放到绿色传送带上，卷轴方向与传送带的运行方向一致。
第一工位是水平式薄膜套管单元。薄膜从成型区上方送入，形成环绕移动毯的连续薄膜管。该单元没有L形杆和腔体夹爪：包装为套管，而非三边袋。
套上套筒的卷筒随后进入一个带有红色加热室的白色隧道。出口处薄膜已绷紧。最后看到的是成品包装放在白色桌子上：主体已覆盖，两端封闭。
录制时长为 65 秒。这不是额定循环周期。我们会根据您提供的卷筒长度和隧道设置来计时。
为什么袖套会在加热前闭合卷筒
地毯卷材两端开口。仅靠卷筒缠绕仍然无法完全封闭这两个开口。而薄膜套管初始长度比卷材长；收缩时，两端多余的薄膜会向内折叠，从而封闭开口。
A chamber or L-bar makes a three-side bag. That suits a compact roll, and the line in our [carpet roll shrinking machine](https://www.fhopepack.com/videos/carpet-roll-shrinking-machine/) post is built that way. A continuous sleeve does not need a jaw as long as the roll. The forming box only has to clear the diameter; the belt carries the length through.
我们根据卷筒直径（OD）和卷筒长度加上末端悬垂量来设定套筒尺寸。薄膜等级是后续设定的。
我们如何运行封闭式热隧道
加热使套筒收缩。由于管子已经包裹住卷筒，一次轧制即可收紧筒体，并将悬垂部分拉到两端。
Belt speed and shrink-tunnel temperature are a pair: too fast and the overhang stays loose; too slow and the film wrinkles or scorches. Both are locked on the panel for that film and roll size. The same pairing appears on our [automatic POF shrink wrapping machine with heat tunnel](https://www.fhopepack.com/videos/automatic-pipe-bagging-and-shrinking-machine/).
隧道功率根据每个项目的具体情况进行配置。我们会将相关数值写在方案文件中。
圆柱卷套管薄膜上浆
对于带套筒的圆筒，我们首先测量其周长，然后测量折叠后圆筒的平铺宽度。我们不会将腔式封口机薄膜图表复制到这台机器上。
周长（毫米）= 卷材外径（毫米）× 3.14。
平铺袖宽（毫米）= 周长 / 2。
袖长（毫米）= 卷长 + 左侧悬垂 + 右侧悬垂。
该表格仅为客户示例，并非卷筒内卷材的尺寸。
| 项目 | 金额 |
|---|---|
| Example roll OD | 350 mm |
| Circumference (350 × 3.14) | 1099 mm |
| Laid-flat sleeve width (1099 / 2) | 550 mm |
| Example roll length | 1200 mm |
| End overhang, each end | 80 mm |
| Sleeve length (1200 + 80 + 80) | 1360 mm |
550毫米指的是卷筒折叠（平铺）后的宽度，并非卷筒在支架上的宽度。如果我们用单卷薄膜卷成卷筒并进行纵向密封，薄膜会更宽；我们在设计方案中会加上密封边距。
套筒隧道式或腔式封口机
Use the sleeve-and-tunnel line when a jaw sealer would be too long, or when you want the ends closed by shrink. Use the chamber-sealer line when the roll is compact and you already run centre-folded film — that family is in the [carpet roll shrinking](https://www.fhopepack.com/videos/carpet-roll-shrinking-machine/) article.
A PE bagger with a high seal bar, the path on our [carpet packing machine](https://www.fhopepack.com/videos/automatic-roll-packing-machine-and-carpet-packing-machine/) post, closes a bag and can feed a tunnel after it. It is not the sleeve former in this clip.
发送外径、长度范围以及是否需要封口。这将决定工作站的顺序。
地毯卷套收缩生产线选型清单
- Largest roll OD on this setup, plus length range and the overhang you want after shrink.
- Roll weight and how it arrives: hand load, or a conveyor from the rolling station.
- Film family and thickness you already buy, or a film we should pair with the tunnel.
- Target rolls per hour from the slowest station, not from a short clip.
- Belt infeed height, discharge height, and floor length for the sleeve unit, the tunnel, and a film-change gap.
- Supply for the tunnel, and air if the seal or film clamp needs it.
- Who changes the film after the line is stopped.
控制与安全
适用的标准取决于目标市场。对于欧盟CE认证市场，ISO 12100规定了风险评估方法，而EN 415-10涵盖了包装机械的通用要求，其中规定了防护装置和紧急停止装置。
成型箱和隧道口是运行中的安全隐患。传送带一旦开始运转，我们就必须确保人员远离这两个开口。换膜和清除堵塞等操作要等到生产线停止后才能进行。
工程常见问题解答
Q: When do we specify a film sleeve instead of a three-side chamber sealer?
A: When roll length would force a very long jaw, or when you want the ends closed by shrink overhang. Compact rolls that already run on centre-folded film stay on the chamber-sealer line.
Q: How do I calculate the sleeve film for my roll?
A: Multiply OD by 3.14 to get the circumference, then halve it for laid-flat tube width. Add left and right overhang to the roll length. On a 350 mm × 1200 mm example that is 1099 mm around, 550 mm laid-flat, and 1360 mm long with 80 mm overhang each end.
Q: What happens if tunnel speed and temperature do not match?
A: If the belt is too fast, the overhang on the ends stays loose. If it runs too slow, the film wrinkles or scorches. We lock both settings for that film and roll size.
Q: Does the sleeve need end seals before the tunnel?
A: Not on this layout. The tube is longer than the roll; heat pulls the extra film onto the ends. If the overhang cannot fold in, we add an end-seal station or we switch to a bagger.
Q: How do we set rolls per hour?
A: Rolls per hour = 3600 ÷ seconds per roll at the slowest station. On this pair the tunnel usually sets the pace. Send the roll length and the film; we close the number on the proposal.
下一步
我们分三步确定地毯卷筒套筒和隧道生产线的尺寸：
1. **Submit your layout drawing** with the roll OD, length, weight, film type and output target, to **info@fhopepack.com**.
2. **Receive a proposal within 48 hours**, including the sleeve station, the heat tunnel and the conveyor match.
3. **Book a site survey** so we confirm the infeed height, the line direction and the space for film change.
