The PE water conveying soft belt production line (i.e.: flat-pull water hose production line) is a water hose production equipment, including an external forming die, an internal sizing die, an extruder, and upper and lower paired clamping rollers. The extruder is provided with an extruder head, an external forming die, an internal sizing die, an extruder head, and clamping rollers arranged in sequence from back to front; the cross-sectional shape of the external forming die includes two upper and lower horizontal U-shaped jackets, and the upper wing of the upper U-shaped jacket and the lower wing of the lower U-shaped jacket are connected as a whole through a side plate, and the cross-sectional shape of the internal sizing die includes an upper horizontal cross plate, a lower horizontal cross plate, an upper vertical plate, and a lower vertical plate. The present invention also provides a water hose production process. The production speed of the water hose can be improved, and the equipment structure is simple and ingenious, the production process is easy to operate, and the inner diameter of the water hose is ensured to be accurate.

PE water belt performance characteristics:

1. Raw material ratio, using biaxial stretching co-extrusion technology, multi-layer composite, anti-aging, high temperature resistance, anti-freezing cracking, high strength, service life up to 5 years.

2. Used as the main water belt for drip irrigation, it is economical and low-cost, which can greatly reduce the pressure on users.

3. The product is easy to install and disassemble and can be reused;

4. The product occupies a small space and has strong mobility;

5. It is small in size and easy to transport. It is transported in standard packaging boxes, 200 meters per disc, and 5 discs per box;

6. The length, specifications and wall thickness of the water belt can be customized according to the actual working pressure of the user.

Main uses of PE water belt:

1. Connect the water source and the main water pipe of the micro-spraying belt/drip irrigation belt;

2. It can be used for sub-membrane drip irrigation, such as seedlings, strawberries, watermelons, tomatoes, etc.;

3. It can also be used for sprinkler irrigation of vegetables, flowers, seedlings, gardens, grasslands, etc.
