Embodiment Construction

[0052] This invention adopts the process of cutting and welding into tubes after pressing the sheet. The difference from the water spray belt formed by blowpipe is that after the water spray belt is filled with water, its two sides are bonded to form wings, so it is also called "double-wing water spray belt". , see Figure 2. In the production process, after the tape is extruded, it is divided from the center, and then the upper side is turned over and translated to align the lower tape, and then the upper and lower tapes are bonded into a tube. Its main production process is as follows:

[0053] I. Extrusion

[0054]The plastic (polyethylene) pellets are extruded after being heated by the extruder. The extrusion port is sheet-shaped, with a width of about 200-250mm. The extruded plastic is strip-shaped, with a width of 150-200mm and a thickness of 0.25-1mm. At this time, the plastic It is still hot and melted, and it enters the tablet press after extrusion. The extruder tha...

Abstract

The invention relates to a manufacturing method for a sprinkler tube and a manufacturing device. A half of a pressed and qualified plastic belt is punctured, holes with regular edges are processed based on designed hole distance and hole diameter; the plastic belt is cut into two pieces from the center line; one piece is turned and horizontally moved to above the other belt piece; the two belt pieces are bonded into a pipe. Plastic extruding, pressing, puncturing, cutting, turning and bonding are all completed during progressive process, thus realizing one-time pipe forming. The manufacturingdevice has the advantages of low price and simple manufacturing technology, cannot be easily damaged during coiling storage and fills the blank of similar products in China.

Description

Technical field [0001] The invention belongs to the field of irrigation, and in particular relates to a method for manufacturing a water belt for sprinkler irrigation and a manufacturing device thereof. Background technique [0002] At present, the sprinkler belt, also known as the sprinkler irrigation belt, the micro-spray belt, and the sprinkler pipe, is a new type of micro-irrigation that has only been developed in the past ten years. The principle is to pass low-pressure water (0.05-0.1Mpa) into the plastic hose, and spray the water through the small holes (0.5-0.1mm in diameter) on the hose wall to irrigate the crops. Due to the cancellation of special sprinklers (nozzles, micro sprinklers, drippers), the structure of the irrigation system becomes very simple, easy to install and use, and it is not easy to be blocked compared with general micro irrigation. At the same time, due to the lower working pressure, it can save Energy consumption, so the development is faster....
