At present, the drip irrigation zone used by domestic water-saving drip irrigation field is mainly single-blade labyrinth type drip irrigation tape, this
Single-blade labyrinth type drip irrigation tape labyrinth flow-path is " Great Wall " shape, and the drip irrigation zone flow of Great Wall shape labyrinth flow-path exists
When 1.8L/H is upper, the discharge uniformity of drip irrigation zone is relatively good, to the former required precision producing drip irrigation zone
The lowest, the performance of anti-blockage of drip irrigation zone is relatively good.But " Great Wall " type list when flow is at below 1.8L/H
The discharge uniformity of wing labyrinth type drip irrigation tape is gradually deteriorated, and the performance of anti-blockage of drip irrigation zone is the most gradually deteriorated, stream
Amount is when below 1.0L/H, and the performance of anti-blockage of drip irrigation zone is worse.For solving these problems, recent design
A kind of zigzag drip irrigation zone, owing to the labyrinth flow-path of this zigzag labyrinth drip irrigating belt have employed zigzag structure,
It is close to turbulent condition after water enters runner, almost without forming speed dead band and whirlpool, this drip irrigation zone
The discharge uniformity having had and performance of anti-blockage.But existing molding wheel for drip irrigation belt can not produce this saw
Profile of tooth drip irrigation zone.
Summary of the invention
It is an object of the invention to provide a kind of molding wheel for drip irrigation belt, it solve the molding of existing drip irrigation zone
The problem that wheel can not produce this zigzag drip irrigation zone.
The technical scheme is that the briquetting roller of this production zigzag drip irrigation zone includes axle, vacuum
Partly, cooling segment and drip irrigation zone moulding section, drip irrigation zone moulding section is positioned on the outer circumference surface of briquetting roller
And it is divided into three districts, it is zigzag labyrinth flow-path shaping area, bonding zone and visionary hope transition region respectively；Zigzag
The vacuum forming process of labyrinth flow-path is responsible in shaping area, labyrinth, and bonding zone is arranged on shaping area, zigzag labyrinth
Both sides, ensure after bonding that shaping area, zigzag labyrinth forms tight cavity, and visionary hope district is that in producing, control is dripped
Fill the region of band pipe diameter size；Zigzag labyrinth flow-path shaping area is the circumferentially continuous row along briquetting roller
The identical vacuum forming groove of many strips of row, each complete vacuum forming groove is by sawtooth shape flow passage negative pressure
Forming tank, water inlet vacuum forming groove, water outlet vacuum forming groove composition, water inlet vacuum forming groove by visionary hope district and
Sawtooth shape flow passage vacuum forming groove connects, water outlet vacuum forming groove and the sawtooth shape flow passage vacuum forming groove other end
Connection, wherein saw zigzag vacuum forming groove is by two row sawtooth projection crown phase on briquetting roller outer circumference surface
Groove between the sawtooth projection of, staggered formation is constituted.
As above-mentioned further restriction, the angle of sawtooth projection is 25 °～50 °, tooth bottom width
0.6mm～1.2mm, the width of sawtooth shape flow passage vacuum forming groove is 0.8mm～1.6mm.
As above-mentioned further restriction, the vacuum forming that two sawtooth projections of every continuous adjacent are constituted
The width of groove be width alternately.
As above-mentioned further restriction, water inlet vacuum forming groove is 5 roads, and water outlet vacuum forming groove is 3
Road.
The invention has the beneficial effects as follows employing this molding wheel for drip irrigation belt can produce discharge uniformity and
The zigzag drip irrigation zone that the hydraulic performances such as performance of anti-blockage are excellent, speed of production is very fast, and production cost is relatively low.
It is further described below in conjunction with the accompanying drawings:
Accompanying drawing illustrates:
Fig. 1 is the sectional view of zigzag drip irrigation zone molding
Fig. 2 is Fig. 1 periphery local expansion figure
Fig. 3 is the partial enlarged drawing of Fig. 2
Fig. 4 is the periphery local expansion figure of another kind of zigzag molding wheel for drip irrigation belt structure
Fig. 5 is the partial enlarged drawing of Fig. 4
Detailed description of the invention
Embodiment 1, with reference to Fig. 1 and combine Fig. 2, the briquetting roller bag of shown production zigzag drip irrigation zone
Including axle 1, vacuum section 2, cooling segment 3 and drip irrigation zone moulding section 4, drip irrigation zone moulding section 4 is positioned at
On the outer circumference surface of briquetting roller and be divided into three districts, it is zigzag labyrinth flow-path shaping area 43, bonding zone respectively
42 and visionary hope transition region 41；The vacuum forming process of labyrinth flow-path is responsible in shaping area, zigzag labyrinth 43, viscous
Close district 42 and be arranged on the both sides of shaping area, zigzag labyrinth 43, after bonding, ensure shaping area, zigzag labyrinth 43
Forming tight cavity, visionary hope district 41 is the region controlling drip irrigation zone pipe diameter size in production；Zigzag labyrinth
