> An offline PVC pipe strapping and bagging line packs cut pipe away from the extruder. Pipes are loaded from stock, counted into a bundle, strapped and slid into a bag, all on one line that runs at its own pace, which suits plants where several extruders share one packing area. Our pipe bagger takes bundles of 180–250 mm from pipes of 20–65 mm and 3–6 m, at more than one bundle a minute. Below: offline vs online, how the line works, bundle sizing, and strapping choices.

线下还是线上：哪种更适合你的植物
| Point | Offline line | Online line |
| :--- | :--- | :--- |
| Position | separate packing area | directly behind one extruder |
| Feed | cut pipe from stock, by operator or loader | straight from the cutter |
| Pace | its own, set by packing demand | set by the extruder |
| Serves | several extruders | one extruder |
| Size changes | handled in the packing area, extruders keep running | change with the extruder |
当一台挤出机无法单独完成整箱包装、管材在包装前需要存放，或者挤出车间每条生产线后方空间不足时，离线式生产模式就非常适用。我们的管材包装线提供在线和离线两种版本。
离线线路的工作原理
1. **Infeed.** Cut PVC pipes are laid on the infeed staging platform. The operator keeps it stocked and squares the pipe ends.
2. **Count and form.** The program counts pipes into the bundle and shapes it to the set diameter.
3. **Strap.** The strapping station binds the bundle at set points as it is conveyed through.
4. **Bag.** The strapped bundle passes into the bagging unit, where film is formed into a bag round it, sealed and cut.
5. **Outfeed.** Finished bundles leave for labelling and storage.
气动驱动装置使用 5-7 巴的气压。捆扎和装袋装置周围设有护栏和盖板，机器带有 CE 标志。
线路数据
| 项目 | 金额 |
| :--- | :--- |
| Pipe OD | 20–65 mm |
| Pipe length | 3–6 m |
| Bundle OD | 180–250 mm (customisable 100–400 mm) |
| Bundle weight | 5–50 kg |
| Output | over 1 bundle per minute |
| Bag film | PE, PP or HDPE, 30–80 micron |
| Strapping | LLDPE stretch film, or PP strap |
| Air | 5–7 bar |
| Pipe types | PVC, PPR, HDPE |
示例：调整捆绑包大小
示例：25 毫米 PVC 管，4 米长，呈六边形捆扎，每边 5 根管子。
| 检查 | 计算 | 结果 |
| :--- | :--- | :--- |
| Pipes per bundle | 3n(n − 1) + 1, n = 5 | 61 pipes |
| Bundle width | (2n − 1) × d = 9 × 25 | 225 mm |
| Fits bagger? | 225 within 180–250 | yes |
| One extruder at 15 m/min | 15 ÷ 4 | 3.75 pipes per minute |
| Time to fill a bundle | 61 ÷ 3.75 | ≈ 16 min |
**Result.** One extruder fills a 61-pipe bundle only every 16 minutes, while the bagger can pack more than one a minute. That gap is why an offline line fed by several extruders, or from stock, uses the bagger far better than an online one.
薄膜表带或PP表带
我们的机器既可使用拉伸膜捆扎带，也可使用PP带捆扎带。我们通常推荐使用拉伸膜捆扎带：它更经济实惠，并且能将捆扎物固定在其整个圆周上。根据生产速度和管道长度，生产线配备一个、两个或三个拉伸膜捆扎工位。PP带捆扎带适合已经使用这种捆扎带的客户，或者需要一种可以现场裁剪和重新捆扎的捆扎带的客户。
选择清单
1. Pipe OD range, lengths and material.
2. Pipes per bundle or bundle diameter.
3. Bundles per hour, and how many extruders feed the line.
4. Film strap or PP strap, and number of strapping points.
5. Bag film type and printing.
安全标准：EN 415-10 和 ISO 12100
包装生产线按照 EN 415-10 标准建造，并根据 ISO 12100 标准进行风险评估。危险部件包括计数成型机构、捆扎装置、加热封口机和移动的管端。防护栏和防护罩确保操作人员远离进料口和移动部件。
工程常见问题解答
Q: Can one offline line serve several extruders?
A: Yes; that is its main advantage. Cut pipe from each extruder is stored on racks, and the infeed platform acts as the buffer. The operator stocks it with one size at a time, so the packing line runs full batches while every extruder keeps its own pace.
Q: Which pipe sizes fit?
A: 20–65 mm OD, 3–6 m long, in bundles of 180–250 mm (customisable 100–400 mm).
Q: Film strap or PP strap?
A: Both work; film strapping is usually more economical and grips the whole circumference, which suits smooth PVC pipe. PP strap is useful where the customer already uses it or wants to re-tie bundles on site.
Q: What bag film is used?
A: PE, PP or HDPE of 30–80 micron.
