Background technique

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 commonly used methods for forming the labyrinth flow channel of the drip irrigation belt include the vacuum suction method and the patch method: the former is to extrude a thin-walled plastic tube first, then flatten the extruded thin-walled tube, and then pass the forming wheel before cooling. The wall plastic tube is pressed into the shape of the labyrinth channel, and the labyrinth channel is sucked out by vacuum suction; the latter is to paste the formed labyrinth channel patch on the tube wall before the plastic tube is cooled and then heat seal. These two processing methods The advantage is that the edge seam drip irrigation belt can be continuously processed and formed. One of the disadvantages is that the drip irrigation belt is extruded, and the molding equipment requires high precision. The thickness of raw materials is relatively high and the cost of materials is relatively high; the second disadvantage is that the above-mentioned equipment production line can only produce one drip irrigation belt, and the production efficiency is low. Therefore, only by designing simpler labyrinth flow channel manufacturing process equipment and reducing system investment can the bottleneck problem of drip irrigation belt popularization in rural areas be solved.

Detailed ways

Schematic diagram of the production equipment of patch labyrinth flow channel drip irrigation tape of the present invention shown in Fig. 1, 2, the working principle of this production equipment forming patch type drip irrigation tape is that a layer of plastic film is continuously thermally laminated under horizontal traction for multiple A patch with a labyrinth flow channel is set in one group, and then covered with another layer of plastic film that is pulled synchronously. After separation and hot pressing, multiple sets of water delivery channels with multiple sandwich patches are formed, and they are cut online into multiple patch drip irrigation belts. .

The drip irrigation belt is made of blown film and the labyrinth channel patch of the same material. The labyrinth channel patch can be prefabricated into any broken line shape. The design and molding of the patch labyrinth channel are mature technologies. Here Needless to say.

As shown in Fig. 1 and Fig. 2: the specific technical scheme of the production equipment of patch type labyrinth flow channel drip irrigation belt includes: motor 13, temperature control device and multiple sets of plastic film reels, hot pressing rollers arranged on the frame 9, the frame up and down Two plastic film reels 2, 22 are set, and the labyrinth runner patch reel 1, upper and lower heat pressing rollers 6, 19, 10, 18, slitting knife roller 11 and finished drip irrigation tape reel 17 are arranged in the middle, and the motor 13 passes through the transmission chain 12 Connect the finished drip irrigation tape reel 17, the cutter roller 11 and the upper and lower hot pressing rollers 6, 19, 10, 18 to rotate synchronously.

The labyrinth channel patch is prefabricated as a rolled patch 3 with equidistant and evenly distributed zigzag labyrinth flow channel units 25 and water inlet holes 24; 2,22,1, by the finished product drip irrigation tape reel 17 traction rotation. Corresponding to the corresponding position of the middle labyrinth channel patch, a puncher 20 is set, and a water outlet hole 21 is punched out on the lower plastic film 4;

The hot pressing is carried out in two steps. First, the first hot pressing rollers 6 and 19 heat-press the labyrinth runner patch 3 and the lower plastic film 4 with the water outlet hole 21 together; then continue to overlap with the upper plastic film 5 , through the second heat-pressing rollers 10, 18 for heat-pressing, and electric heating sheets 7 are distributed axially on the heat-pressing rollers at intervals to form several water delivery channels as shown in FIG. 3 . After lamination, a plurality of finished drip irrigation belts are simultaneously obtained by slitting by the slitting knife roller 11. In practical application, irrigation water enters the labyrinth flow channel unit 25 through the labyrinth flow channel inlet hole 24 in the drip irrigation belt as shown in Figure 4, and the energy dissipation effect of the labyrinth flow channel makes the pressurized water irrigation water in the pipe become unpressurized Irrigation water drips out by the water outlet hole 21 of the labyrinth flow channel at last.

The hot pressing roller of the present invention is arranged up and down, and the heating surface of the hot pressing roller is arranged at intervals. One side is set, and the other side is a smooth roller, which can heat the drip irrigation belt on one side.

In order to ensure that the linear speed of the above-mentioned drip irrigation belt is constant during processing, the traction motor 13 of the present invention selects the finished drip irrigation belt reel 17 pulled by the torque motor, and the whole device drives the first hot pressing roller 6, 19 through the drive chain 12 connected by the motor It rotates synchronously with the second hot pressing rollers 10, 18 and the cutter roller 11 to complete the whole process.

If an ordinary deceleration motor is used as the traction power, the extended technical solution provided by the present invention is to have a winding roller 16 outside the finished product reel 17, and the winding roller is close to the finished product under the action of the rocker arm 15 and the compression spring 14. On the drip irrigation belt, the finished reel 17 is driven to rotate under the action of friction, as shown in Figure 5.

As mentioned above, the main innovation of the present invention is to use a single machine to hot-compress multiple patch drip irrigation belts at the same time. The present invention changes the working mode of extrusion and vacuum blister equipment, and can be widely used in the packaging industry. The blown film also effectively solves the technical problem that the thin-walled drip irrigation tape is not easy to absorb and stretch, and is compounded with the labyrinth channel patch of the same material. Strip drip irrigation belt, the processing process is simple, and the processing precision is high.

In the production equipment of the present invention, the hot pressing roller is designed as a correspondingly spaced heating surface according to the specifications of the drip irrigation belt water delivery channel and the labyrinth flow channel. During the pressing process of the labyrinth flow channel and the plastic film edge pressing process, the hot pressing roller is in contact with the entire surface. The precision is higher than the point contact of vacuum blister roller pressing, and because it is flat roller hot pressing, the requirements for equipment precision are not high, and its comprehensive cost performance is significantly improved compared with the existing technology.

The above descriptions are only proposed as several implementable technical solutions of the patch type labyrinth channel drip irrigation belt production equipment of the present invention, and are not regarded as limitations on its structure or technology.
