The specific embodiment
Paster maze flow passage drip irrigation belt production method principle schematic of the present invention shown in Fig. 1,2, this drip irrigation zone uses inflation film and the pressing of equivalent material labyrinth flow-path paster distributed heat to make, the labyrinth flow-path paster can be prefabricated into any broken line shape, the design of paster labyrinth flow-path and moulding all belong to mature technology, need not give unnecessary details at this.
Operation principle comprises: drip irrigation zone of the present invention is formed by labyrinth flow-path paster 3 hot pressing of two layers of plastic thin films 5,4 and middle sandwich setting up and down, and the labyrinth flow-path paster is made as the rolling paster 3 of equidistant uniform broken line shape labyrinth flow-path unit 25 and inlet opening 24 in advance; In process, plastic sheeting 5,4 and paster 3 are wrapped in respectively on the corresponding spool 2,1,22, are rotated by 17 tractions of finished product spool.Apopore 21 is got in the relevant position of labyrinth flow-path paster in the middle of corresponding on lower floor's plastic sheeting 4; Hot pressing is carried out at twice, at first by the first road hot pressing roller 6,19 labyrinth flow-path paster 3 and lower floor's plastic sheeting 4 hot pressing of getting apopore 21 is in the same place; It is overlapping with upper strata plastic sheeting 5 to move on then, carries out hot pressing through the second road hot pressing roller 10,18, and axially spaced-apart distribution electric heating sheets 7 forms several water transport channel as shown in Figure 3 on the described hot pressing roller.Cut and obtain many finished product drip irrigation zones simultaneously through cutting rotor 11 again.
In order to guarantee the linear velocity constant of above-mentioned drip irrigation zone in process, the present invention selects the finished product drip irrigation zone spool 17 of torque motor traction, entire equipment connects the drive first road hot pressing roller 6,19 and the second road hot pressing roller 10,18 of driving chain 12 by motor and cuts rotor 11 and rotate synchronously, finishes whole process.
If use common reducing motor as traction power, the elongation technology scheme that the present invention provides is to be provided with wind-up roll 16 in finished product spool 17 outsides, wind-up roll is under the effect of rocking arm 15 and holddown spring 14, be close on the finished product drip irrigation zone, under the effect of frictional force, drive finished product spool 17 and rotate, as shown in Figure 5.
As previously mentioned, main innovate point of the present invention is to utilize unit many SMD drip irrigation zones of hot pressing simultaneously, the present invention has changed the traditional handicraft of extruding with vacuum forming, use the lower inflation film of cost, the drip irrigation zone that also effectively solves thin-walled is difficult for the technical problem that plastic uptake stretches, the design concept of the SMD drip irrigation zone of the present invention and production method are to utilize the inflation film of packaging industry extensive use, compound with the labyrinth flow-path paster of identical material, can process several drip irrigation zones simultaneously, process is simple, the machining accuracy height.
Production method of the present invention, the hot pressing roller is the heating surface of corresponding interval according to the specifications design of drip irrigation zone water transport channel and labyrinth flow-path, in labyrinth flow-path pressing and plastic sheeting flanging process owing to be whole and contact, the hot pressing precision wants high compared with the some contact of vacuum forming roller pressing, and owing to be plain-barreled roll hot pressing, not high to equipment precision requirement, its comprehensive price ratio has marked improvement than prior art.
Drip irrigation zone of the present invention in actual applications, irrigation water enters labyrinth flow-path unit 25 by labyrinth flow-path inlet opening 24 in the drip irrigation zone as shown in Figure 4, becomes nothing through the pressure water irrigation water in the feasible pipe of the energy dissipating effect of labyrinth flow-path and presses irrigation water to be oozed by labyrinth flow-path apopore 21 at last.
Foregoing description only proposes as several enforceable technical scheme of paster type maze flow passage drip irrigation belt production method of the present invention, and conduct is not to its structure or technology limitation condition.
