Description
Technical field
The present invention relates to the pelletizing template of granulation underwater is carried out to hot melt, particularly a kind of high open-ratio granulating template,
Suitable for hot melts such as PE, PP, EVA, TPEE, transparent butadiene-styrene impact resin, polyamide, PURs.
Background technology
During hot melt granulation underwater, pelletizing template is crucial production part.The general cloth of existing template discharge opening
Put in even number fan section, the set in all fan sections constitutes granulation band, due to reasons in structure, can not near sector edge
Arrangement discharge opening, each discharge opening in fan-shaped central region averagely undertake area of dissipation than in fan-shaped fringe region
The area of dissipation that each discharge opening averagely undertakes is little, in short, entirely granulation band has thermograde.As pelletizing template discharges
Side need to be immersed in the cooling circulating water of flowing, therefore necessarily causes heat to scatter and disappear, and area of dissipation is little to also imply that rapid heat dissipation.
For these reasons, existing pelletizing template is primarily present following problem：Firstly, since being disposed with template hundreds of
Individual, even thousands of discharge opening, uniform essential condition is to make each extrusion cavities throttle to be formed as far as possible will to make each discharge opening discharging
Necessary pressure differential.But if the pressure differential for being formed is little, the pressure drop that other any interference (such as thermograde) are caused all can
Become principal contradiction, cause discharge opening discharging uneven, this is the problem that many pelletizing templates are present at present.Secondly, granulate mould
Operationally, with close to fan-shaped edge, die plate temperature is gradually lowered plate, and temperature is low, causes hot melt viscosity to increase, goes out
The discharging of material hole is gradually decreased, or even " freezing to death " does not discharge, and so as to cause each discharge opening discharging uneven, ultimately causes template percent opening
It is low.
In order to solve the problems, such as pelletizing template discharge opening discharge uneven, template percent opening it is low, United States Patent (USP) US 4,752,
196 and US 4,856,974 give the heat insulation schemes for spraying zirconia barrier layer under orifice plate between each row discharge opening.These sides
Case entirely granulates region surface radiating measurer to reduction template positive effect, but and unresolved scallop edge area die plate temperature
Low this root problem, and cause orifice plate to reduce with template brazing contact area, template strength is affected, while it is tired to manufacture processing
It is difficult.And Japan Patent JP 8-192423 and JP 10-264251, German patent DE 4036196 provide the true of different structure respectively
Empty heat insulation schemes, these schemes entirely granulate region surface radiating amount equally with positive effect to reducing template, but also simultaneously
Low this root problem of unresolved sector marginal zone die plate temperature, and due to being restricted by structural requirement, heat tracing passage between discharge opening
Nearer with hole distance between plates, Vacuumed insulation panel difficult arrangement manufactures processing difficulties.
Therefore, the version of existing hot melt pelletizing template still needs to improve.
The content of the invention
The invention aims to providing one kind fundamentally solves the uneven, mould of existing pelletizing template discharge opening discharging
The high open-ratio granulating template of the low problem of packing free ratio, easy to manufacture, reliability are high, eliminate thermograde, when being granulated

Thermal medium inlet hole, at least one heat tracing medium portal and some screw mounting holes, be machined with the orifice plate with extrusion cavities
Some discharge openings that heart line overlaps, it is characterised in that：The discharge opening and extrusion cavities equal diameters, the extrusion cavities and discharge opening
Total length sum with extrusion bore dia ratio be not less than 6.
Above-mentioned high open-ratio granulating template, the template parent material are that thermal conductivity factor is not more than 18wm under room temperature-1k-1
Stainless steel.
Above-mentioned high open-ratio granulating template, the orifice plate material are that thermal conductivity factor is not more than 21wm under room temperature-1k-1,
High-abrasive material containing carbide composition.
Above-mentioned high open-ratio granulating template, the orifice plate material are that thermal conductivity factor is not more than 18wm under room temperature-1k-1No
Rust steel, is evenly arranged little cylinder and paxilla on the orifice plate, the little cylinder and paxilla material are thermal conductivity factor under room temperature
No more than 21wm-1k-1, the high-abrasive material containing carbide composition, the discharge opening is the endoporus of little cylinder.
Above-mentioned high open-ratio granulating template, the orifice plate are by thermal conductivity factor under room temperature is not more than 21wm-1k-1
, the high-abrasive material powder containing carbide composition be sprayed on what is realized on template parent.
Above-mentioned high open-ratio granulating template, the carbide are tungsten carbide, titanium carbide or both combinations.
Above-mentioned high open-ratio granulating template, between the hole, the top surface of the close orifice plate of heat tracing passage is coated with thermal insulation layer,

Above-mentioned high open-ratio granulating template, the insulating layer material are zirconium oxide.
Above-mentioned high open-ratio granulating template, the thickness of the orifice plate is 1mm～5mm.
The invention has the beneficial effects as follows：
1st, after years of research and found that, each extrusion cavities discharging that the extrusion bore region on template parent is made is tried one's best uniform
Essential condition is to make each extrusion cavities throttling to form necessary pressure differential, and reaches each extrusion cavities and throttle to form necessary pressure
The means of difference this purpose are to make extrusion cavities be not less than 6 with discharging hole length sum and extrusion cavities diameter ratio value, and hot melt melts
Melt index lower (mobility is poorer), above-mentioned ratio should more be close to 6, based on above-mentioned extrusion cavities and the size characteristic of discharge opening, respectively
Discharge opening discharging is uniform, template percent opening is high, pressure load is low.
2nd, due to the presence of thermal insulation layer, when template parent runs, orifice plate whole region temperature is essentially identical, while making heat
Scatter and disappear less, to save the heat tracing energy, cooling water heat load low.
3rd, simple structure, easy to manufacture, reliable.
To sum up, the present invention is by establishing extrusion cavities, discharge opening physical dimension, making each extrusion cavities throttle to form necessary pressure
Power is poor；From selecting low thermal conductivity material manufacture template, taking provision for thermal insulation etc. to set about, improve pelletizing template effect of heat insulation, make
When template is run, granulation band is reduced to minimum level with thermograde, so as to fundamentally solve existing pelletizing template discharging
The uneven, problem that template percent opening is low of hole discharging.
