The special processing equipment of extruded type vacuum provided by the invention heat-sealing drip irrigation zone is as Fig. 1～shown in Figure 2.This equipment is by bimodulus head screw extruder, be arranged at the flexible pressure roller 15 and the water-cooled vacuum forming roller 10 of extrusion die below, and the idler roller 17,18,19,20 that is set in turn in the shaping station rear, be arranged at the cutting cutter 11 between the idler roller, be arranged at the flattening wheel 21 at cutting station rear and twine axle 22 and form.Described water-cooled vacuum forming roller 10 is sleeved on the fixation hollow axle 10-11 by rotational forming wheel 10-10 to be formed, being provided with fixedly around hollow shaft, water jacket 10-9 constitutes cold water cavity 10-7, axially be provided with vacuum chamber 10-9-1 between hollow shaft and the rotational forming wheel, during work, end face ratchet by sprocket wheel 10-14 and rotational forming wheel end face ratchet engagement, driven rotary briquetting roller 10-10 serve as a rotation with fixing water jacket (10-9).As shown in Figure 5.
Rotational forming wheel 10-10 outer surface is provided with the annular ridge 10-6 of constant spacing vertically, annular groove and the uniform through hole 10-5-2 that bleeds, inlay the annular labyrinth moulding ring 10-5 that cross section is a rectangle in Fig. 6, Fig. 7, the annular groove shown in Figure 9, every moulding ring outer surface along the circumferential direction is carved with N organizes equally spaced labyrinth groove 10-5-3, the labyrinth that bottom portion of groove the is provided with diameter 0.5～0.6mm through hole 10-5-1 that bleeds is communicated with the bigger through hole 10-5-2 that bleeds of rotational forming wheel circumference uniform distribution, bleed diameter 2～3mm of through hole 10-5-2, pitch of holes 10～12mm.When rotating to the vacuum chamber 10-9-1 position of water-cooled axle, the through hole 10-5-2 that bleeds forms vacuum condition, rotational forming wheel outer surface between annular ridge 10-6 and labyrinth moulding ring 10-5, aspirate out the drip irrigation zone and cross aquaporin 10-5-5, water maze aspirates out in groove 10-5-3 place in the labyrinth, simultaneously the drip irrigation zone of annular ridge 10-6 and annular labyrinth moulding ring 10-5 bossing and flexible pressure roller pressing semi-molten state.
Rotational forming wheel 10-10 other position of inner surface and vacuum chamber 10-9-1 isolate, and do not form vacuum condition, and contact with fixation hollow axle external diameter surface, and water flowing cooling surface and appearance generating surface distance are 13～15mm, are convenient to briquetting roller and cool off fast.
The labyrinth groove 10-5-3 of labyrinth moulding ring 10-5 can be carved into arbitrary shape by the hydraulic performance requirement.After rotational forming wheel 10-10 inlayed labyrinth moulding ring, moulding ring external diameter was identical with the annular ridge external diameter.
Vacuum chamber 10-9-1 shown in Figure 4 is connected with hollow shaft 10-11 by the transition conduit 10-8 that bleeds, and hollow shaft one end blocks, and an end connects bleeding point 10-1, and bleeding point is connected with vavuum pump 30 by vacuum exhaust pipe 23, vacuum suction valve 28.
Shown in Figure 8, fixation hollow axle 10-11, fixedly water jacket 10-9 and end cap 10-4,10-12 constitute cold water cavity 10-7, and cooling water intake 10-3-1 and delivery port 10-3-2 are set on the end cap.
The process equipment of described extruded type vacuum heat-sealing drip irrigation zone, described cutting cutter 11 swords with become 100～120 to spend angles above the plastic tab.
When equipment was installed, clockwise 10～12 degree in the center of flexible pressure roller cylindrical and format roll water-cooled axle sleeve vacuum chamber were tangent.
The operation principle of the process equipment of this extruded type vacuum heat-sealing drip irrigation zone comprises:
After A, furnish component mix, insert the extruder elevating hopper;
B, extrude: adjust A, B, C, the D district heating-up temperature of extruding machine barrel heater (5), after the holding temperature of die head angle coupling (6), startup extruder drive motors is extruded two different plastic tab A of thickness, B at extrusion mould-outlet A, B;
C, drip irrigation zone moulding: two plastic tab A, B that extrude are by hang down space between flexible pressure roller 15 and the water-cooled vacuum forming roller 10 of gravity, at flexible pressure roller and water-cooled vacuum forming roller simultaneously, water-cooled vacuum forming roller the crossing aquaporin and go out water maze of many drip irrigation zones of vacuum draw moulding on thick B sheet at the pressing plastic tab.
Concrete operations comprise: start the format roll drive motors simultaneously in extruder work, be driven into forming roll 10, start cylinder 14 then, cylinder piston promotes flexible pressure roller shaft, evenly is pressed on the water-cooled vacuum forming roller of installation in parallel.At this moment, flexible pressure roller rotates with the format roll synchronous backward under format roll drives.
Be adjusted to the forming roll velocity of rotation, under format roll and flexible pressure roller pressing effect, one side stretches, draws, cools off the semi-molten state plastic tab, one side needs bonding position bonding rapidly the two layers of plastic thin slice, by vacuum draw, aquaporin is crossed in many drip irrigation zones and go out water maze suction moulding simultaneously.
In equipment when work,, format roll water-cooled axle sleeve feeds cooling water, opens extraction valve 28, starts vavuum pump 30, and suction plastic tab B made aquaporin and went out the water maze moulding, and A, B two layers of plastic thin slice are bonding simultaneously, and the working vacuum degree is regulated by air bleeding valve 27;
D, cutting: whole plastic tab of moulding is cut into the wall scroll drip irrigation zone simultaneously through idler roller, passes through nip rolls 21 then, be wrapped in again and twine on the axle 22, every drip irrigation zone after the cutting is all fully flattened.
As previously mentioned, main innovate point of the present invention is and supporting large-scale molding wheel for drip irrigation belt and vacuum draw and cooling system and the structures that designed many water flow passage excessively and gone out water maze of bimodulus head plastic extruder, the present invention has changed the equipment working method of extruding with vacuum forming, under the prerequisite that guarantees machining accuracy, increase substantially the production efficiency of plastic uptake drip irrigation zone, can process 12-24 bar drip irrigation zone simultaneously.
Foregoing description only proposes as the processing method of a kind of extruded type vacuum heat-sealing of the present invention drip irrigation zone and several enforceable technical scheme of equipment, and conduct is not to its structure or technology limitation condition.
