电缆线环体缠绕膜包装机是一种专门用于电线电缆等圆柱形产品表面缠绕包装薄膜的自动化设备。这类机器通常采用可编程逻辑控制器（PLC）进行控制，通过伺服电机驱动的转盘或输送装置，使电缆线环体匀速旋转，同时配合安装在高精度导轨上的拉伸膜架，将缠绕膜均匀、紧密地包裹在电缆线环体外表面。

工作原理主要包括以下几个步骤：

1. 

放线

：将电缆线环体放置在转盘或输送带上。

2. 

启动

：启动包装机，转盘开始转动或输送带开始移动，带动电缆线环体旋转或前进。

3. 

拉伸裹膜

：薄膜从膜架上拉出，并通过预设的张力控制系统进行拉伸，然后贴合在电缆线环体上。

4. 

环绕包裹

：随着电缆线环体的旋转或移动，薄膜不断地环绕在其表面形成多层包裹，确保产品的防尘、防潮及固定作用。

5. 

断膜与粘贴

：当达到预设的包裹层数或圈数后，包装机会自动切断薄膜，并通过热熔胶系统或搭接的方式完成薄膜尾部的粘贴固定。

这种包装机广泛应用于电线电缆制造业，能大大提高生产效率，减少人工成本，同时提升产品的外观质量和储存运输过程中的安全性。

Cable loop body stretch film packaging machine is an automatic equipment specially used for winding packaging film on the surface of cylindrical products such as wires and cables. This kind of machine is usually controlled by a programmable logic controller (PLC), and the cable loop body rotates at a constant speed through a turntable or conveying device driven by a servo motor, and at the same time, with the stretch film frame installed on the high-precision guide rail, the winding film is evenly and tightly wrapped on the outer surface of the cable loop.

The working principle mainly includes the following steps:

1. 

Pay-off

: Place the cable loop body on a turntable or conveyor belt.

2. 

initiate

: Start the packaging machine, the turntable starts to rotate or the conveyor belt starts to move, driving the cable loop to rotate or advance.

3. 

Stretch wrap

: The film is pulled from the film rack and stretched by a preset tension control system, and then laminated to the cable loop.

4. 

Wrap around

With the rotation or movement of the cable loop, the film continuously surrounds its surface to form a multi-layer wrap to ensure that the product is dustproof, moisture-proof and fixed.

5. 

Breaking the film and pasting

When the preset number of layers or turns is reached, the packaging machine will automatically cut the film and complete the gluing and fixing of the film tail by hot melt adhesive system or lap joint.

This kind of packaging machine is widely used in wire and cable manufacturing industry, which can greatly improve production efficiency, reduce labor costs, and improve the appearance quality of products and safety during storage and transportation.
