Problems solved by technology

[0004] One of the purposes of the present invention is to provide a drip irrigation tape and a production method for printing and processing labyrinth flow channels, to simplify the technology and equipment of the drip irrigation tape, reduce the wall thickness and weight of the drip irrigation tape at the same time, and solve the high production cost of the drip irrigation tape. Can not afford the problem; the second purpose of the present invention is to solve the strength problem of the labyrinth flow channel on the thin-walled drip irrigation belt

Embodiment Construction

[0024] The structure schematic diagram of the printed labyrinth flow channel drip irrigation tape of the present invention shown in Fig. 1 after water filling, this drip irrigation tape has no concave-convex stretching surface before water filling, and is no different from the general light belt, and the labyrinth flow channel can be printed in theory Make any polyline shape.

[0025] As mentioned above, the main innovation point of the present invention is to solve the problem that the thin-walled drip irrigation belt is not easy to absorb and stretch and the cost of vacuum absorbing equipment is too high, and the blown film widely used in the packaging industry is used to print on the film. Composite and heat-sealable labyrinth flow channel 2, and then press the hot pressing edge 5 that has not been printed with the labyrinth flow channel through the hot pressing flat roller to form the labyrinth flow channel, and the manufacturing cost is much lower than the existing extrusi...

Abstract

The present invention provides a drip-irrigation band with printed labyrinth flow channel. It is composed of water-conveying channel, hot-pressed edge with several groups of labyrinth flow channel units, labyrinth flow channel water inlet and water outlet. It is characterized by that the described labyrinth flow channel is the hot-pressed gap formed from heat-resisting layer printed on the plastic.

Description

technical field [0001] The invention relates to a drip irrigation tape with a printed labyrinth flow channel and a processing method thereof, belonging to the technical field of agricultural water-saving irrigation equipment. Background technique [0002] Drip irrigation is the most water-saving irrigation technology. The drip irrigation belt is one of the main drip irrigation components. Through the labyrinth flow channel on it, the pressure water flow can be changed into small flow water droplets or trickles that slowly drip or flow out. However, at present, due to the high investment in the early stage, the application of this technology is limited in the vast rural areas, especially the poor areas with drought and water shortage. At present, the main processing method of the edge seam drip irrigation belt with the lowest price is: extrude the thin-walled plastic tube through the extruder, flatten the extruded thin-walled tube, and then press the thin-walled plastic tube ...
