Non-penetrating multi-layer continuous hose and a preparation method thereof

A method for preparing a multi-layer continuous hose using a mold, an asynchronous production control and an L-shaped production line layout, comprising the following steps:

• (1) performing the asynchronous production control between equipment of a production line;
• (2) installing an internal and external combination mold;
• (3) arranging the L-shaped production line layout;
• (4) activating a circular loom and controlling a production speed to weave a reinforcement layer;
• (5) feeding the reinforcement layer into a traction system through the mold, activating a traction machine, and then activating an upper extruder of an inner layer and a lower extruder of an outer layer after a steady cycle of the circular loom, and extruding a coating material of the inner layer and a coating material of the outer layer through the mold simultaneously, and adjusting an extrusion speed of the upper extruder and an extrusion speed of the lower extruder, respectively, to obtain a predetermined thickness of the inner layer and the outer layer;
• and
• (6) after the multi-layer continuous hose is formed, shaping the multi-layer continuous hose by a cooling spray device, and cutting the multi-layer continuous hose to a predetermined length.
