水管卧式环体缠绕膜包装机是一种专门用于对圆柱形物体，例如水管等进行自动化缠绕膜包装的机械设备。这种机器通常设计为卧式结构，适应于较长且不适合立式包装的管材产品。工作原理是通过将环体（即水管）放置在可旋转的承托装置上，然后利用预拉伸的缠绕膜按照预定的程序和层数紧密地包裹在水管表面，形成一层或多层保护膜，以达到防尘、防潮、防腐蚀及避免运输过程中因碰撞而造成的损伤的目的。该类包装机常具备自动控制薄膜张力、裹包层数以及速度调节等功能，提高包装效率的同时确保包装质量稳定可靠。

Water pipe horizontal ring stretch film packaging machine is a kind of mechanical equipment specially used for automatic stretch film packaging of cylindrical objects, such as water pipes, etc. This type of machine is usually designed as a horizontal structure, which is suitable for tubular products that are longer and not suitable for vertical packaging. The working principle is to place the ring body (i.e., the water pipe) on the rotatable supporting device, and then use the pre-stretched winding film to tightly wrap the surface of the water pipe according to the predetermined procedure and number of layers to form one or more layers of protective film, so as to achieve the purpose of dustproof, moisture-proof, anti-corrosion and avoid damage caused by collision during transportation. This type of packaging machine often has the function of automatic control of film tension, number of wrapping layers and speed adjustment, etc., to improve packaging efficiency and ensure stable and reliable packaging quality.
