Embodiment Construction
[0042] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0043] Fig. 1 is a schematic diagram of a processing device for a thin-walled drip irrigation belt according to the present invention, and Fig. 2 is a top view of Fig. 1; as shown in Figs. 1 and 2.
[0044] The present invention passes through the labyrinth channel forming device that is made of upper and lower rollers 7, 12 on the drip irrigation belt base material (blown film) below 0.1mm, vacuum absorbs plastics, heat-compresses, and processes the labyrinth channel, specifically Processing steps include:
[0045] 1. The base material 1 of the drip irrigation tape is moved horizontally by the drip irrigation tape winding wheels 22, 23 which are arranged in front of and behind the labyrinth channel forming device and run synchronously, and the conveying roller 21;
[0046] 2. The base material 1 of the drip irrigation belt is formed ...

Abstract
The invention provides a processing method for a thin wall labyrinth drip irrigation belt. The drip irrigation belt is manufactured by rolling and vacuum pulling-in pre-blow molding thin film base material with the wall thickness being less than 0.1mm to form a labyrinth flow passage. The invention also provides a shaping device for the thin wall labyrinth drip irrigation belt. The processing method of the invention can reduce the wall thickness of the drip irrigation belt and the extruding manufacture cost greatly and improve the uniformity of the drip irrigation belt greatly and can be matched with a shaping device for a special labyrinth flow passage; an elastic rolling wheel is adopted for vacuum pulling-in on a plastic film base to process two groups of labyrinth flow passages with symmetrical mirror images, thus leading the quality of the thin wall labyrinth drip irrigation belt to be more easily controlled.
Description
technical field [0001] The invention relates to a processing method of a thin-wall labyrinth drip irrigation belt and a forming device 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 outlet holes on it, the pressure water flow can be changed into small flow 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 into a labyrin...
