Features: Maze-type drip irrigation hose production line adopts the method of Maze-type flow channel by negative pressure forming, that is, after the materials are extruded, directly form the flow with negative pressure. If changing the negative pressure device, differenct types or differenct spacing flow channel will be formed, So it has many advantadges, such as little processing techniques, high adaptability, stable quality, etc. The line is composed of the extruder, the hall off machine, the taking-up equipment and the drip irrigation hose forming machine. Extruder adopts new type and high effective screw, has high output, the effect of plasticization is good. The die is by heat treating. Adopts electronic auto-control the width, it resolves the disadvantage that the quality is not easily controlled. also ensure the stability of film bubbles when the film is been forming speedly. The forming machine adopts the air cooling and water-cooling together. It ensures the cooling when production high-speedly. winding adopts optical sensor new winding displacement, it changes the situation of overlap when coiling the edge by the spiral type to and fro axis. The components of electric appliances are all the domastic famous brands, adopts frequency conversion timing control and auto-alarm the length counting devices.
