Inflatable punching method and punching equipment for micro-spraying belt

Abstract

The invention discloses an inflatable punching method which comprises the following steps of: a, extrusion sealing: forming an AB segment in a sealed state; b, inflation: inflating into the AB segment of the micro-spraying belt; c, punching: punching on a single side in a state that the AB segment is airtight; d, traction: pulling out the punched micro-spraying belt; and e, finishing the punching of the whole micro-spraying belt. The punching equipment disclosed by the invention comprises two rear pressure rollers, a punching pressure roller and a front pressure roller; when in work, the micro-spraying belt between the rear pressure rollers and the front pressure roller is in an inflation state; and the punching pressure roller is provided with a punching device for punching on the wall of the micro-spraying belt attached to the punching pressure roller. Through the inflatable punching method and equipment disclosed by the invention, single-sided punching is realized, the situation of punching both sides of the micro-spraying belt is avoided, and the occurrence of narrow holes, closed holes and blind holes is avoided. By adopting the spraying irrigation of the micro-spraying belt, the beneficial effects of water conservation, energy conservation and uniform spraying irrigation can be realized; and the equipment has a reasonable structure and good beneficial effects and is convenient to popularize and use.

Description

technical field [0001] The invention relates to an inflatable punching method and punching equipment for a micro-spray belt, more specifically, to a punching method and punching equipment for single-side punching with a micro-spray belt in an inflated state. Background technique [0002] The pressure difference micro-water irrigation network is a systematic project integrating energy saving, water saving and micro-irrigation water delivery. In addition to requiring correct theory, reliable water delivery and stable water head, it must also ensure that the terminal emitters of the system ( That is, the water outlet holes on the micro-spray belt) are of the same size and cannot be blocked, so as to ensure uniform water outlet and stable and effective operation of the entire irrigation network. For example, the Chinese utility model patent with the patent number 200920089965.7 and the title of the invention "A Micro-irrigation Network Equipment for Pressure Difference Eliminati...

AI Technical Summary

Problems solved by technology

Existing perforation technology on the micro-spray tape, instead of the situation of narrowed holes, closed holes and impermeable holes, the micro-spray tape will be pierced, so that two opposite surfaces of the micro-spray tape are sprayed with water. hole, so that it cannot be used normally

The fundamental reason is that the existing punching technology and punching equipment are not mature enough; for example, the patent No. CN200620116926.8 and the utility model patent named "Micro-spray belt punching machine" disclose a kind of continuous operation. Micro-spray belt punching machine, to overcome the existing pause punching technology, the punching principle is to place the synchronous shuttle in the micro-spray belt to achieve punching

During the use of this kind of equipment, the synchronous shuttle needs to be placed in the workpiece, which is not only cumbersome, but also not easy to control

It has the disadvantages of complex equipment, inconvenient use and low work efficiency
