Method and equipment for processing multiple cylindrical microporous labyrinth drip irrigation belts

Abstract

The invention provides a method for machining a plurality of cylindrical micro-pore labyrinth drip irrigation tapes. The method comprises the following steps: arranging extruding die openings A and B on a plastic thin film extruder and extruding fused-state plastic thin film sheets a and b; arranging a line rope feeding mechanism between two layers of plastic thin films; taking two of a plurality of woolen yarn ropes fused as cylindrical labyrinth fillers as a group and respectively inserting the woolen yarn ropes between the two plastic thin film sheets a and b in parallel; when the film sheets are stretched at a semi-fused state, sticking thin film parts by extruding forces of a vacuum molding roller and a flexile pressing roller; meanwhile, pumping by vacuum and pumping and molding an inner water outlet and an outer water outlet of a cylindrical micro-pore labyrinth on a bonding surface; and sectioning by a cutter to form the plurality of cylindrical micro-pore labyrinth drip irrigation tapes and one edge of each cylindrical micro-pore labyrinth drip irrigation tape is composed of a line rope. According to the method, the anti-blocking performance can be greatly improved and filtering equipment of a drip irrigation system is simplified; the operation energy consumption of the drip irrigation system is reduced.

Description

technical field [0001] The invention relates to a processing method and equipment for a plurality of cylindrical microporous labyrinth drip irrigation belts, in particular to a production method and equipment for drip irrigation belts suitable for field crop buried applications, and belongs to the technical field of water-saving irrigation agricultural equipment. Background technique [0002] Various drip irrigation pipes and drip irrigation belts currently used in the field of agricultural micro-irrigation technology are equipped with a set of labyrinths at the front of each drip outlet to damp and reduce the internal pressure of the drip irrigation pipe / belt, and to balance the output of each drip outlet. Pressure and water output, so as to ensure that the water output of each drip outlet is basically the same within a certain laying length of the drip irrigation pipe / belt. The labyrinth is roughly divided into two categories, one is formed separately, and then embedded in...
