Description
Technical field
The utility model relates to a kind of plastic extrusion, injection, conveying equipment machine barrel, in particular to a kind of band internal spiral sulcus
The machine barrel of slot.
Background technique
Machine barrel that plastic extruder currently on the market, injection molding machine use the disadvantage is that: energy consumption is high, waste of resource；It squeezes out
Yield is not high, low efficiency；Machine tube inner wall is not wear-resisting, and service life is short etc..And there are one serious for this traditional machine barrel
Defect is primarily adapted for use in the extrusion of plastic grain of uniform size, is not suitable for irregular particle and powdered plastics
Extrusion.But dusty raw materials are cheap in the market, stronger than competitiveness with particulate material.
Summary of the invention
Problem to be solved in the utility model is exactly to overcome the problems, such as and avoid above-mentioned and disadvantage, provides a kind of new belts
The machine barrel of inter-spiral groove, while the new-type machine barrel can both produce graininess and dusty raw materials, can also produce size not
The plastic crushing material of rule.The new-type machine barrel is high with transfer efficiency, plasticizing effect is good, mixing is uniform, low power consumption and other advantages.
The utility model relates to machine barrel be made of flange, strong cooling section, spout, melt zone.The utility model relates to
And machine tube inner wall at least there are a spiral grooves, length can be grown as machine barrel, can also there was only cooling section position
Corresponding length, do not determined according to the characteristic of plastic raw materials and required production efficiency mainly.The machine barrel of the utility model
The rotation direction of the spiral grooves of inside is oppositely oriented with the screw rod that matches.It is for raw material to be extruded into using the advantages of spiral grooves
Helical form, and shearing thrust is formed with raw material in screw rod screw channel, select suitable lead of screw, it is possible to reduce shearing force,
Increase push power, to improve the transfer efficiency of raw material.
Machine barrel involved in the utility model be furnished with strong cooling section, the structure be directly be machined with inside strong cooling section it is cold
But medium channel.It is passed through after cooling medium, directly progress heat exchange can quickly take away plastic raw materials and rub with machine barrel, screw rod
Wipe the extra heat generated.The length of the strong cooling section is the characteristic according to plastic raw materials and designs, cooling effect meeting
Directly affect the transfer efficiency of machine barrel.Guarantee that raw material conveys at low temperature, the frictional force of raw material and machine barrel can be increased, thus real
The conveying of the high pressure of existing raw material, and fluctuation of the head pressure to conveying yield can be overcome.
Machine barrel involved in the utility model is furnished with spout, and the design of spout uses asymmetric eccentric structure, difference
In traditional symmetrical spout, is conducive to the feed quantity for improving raw material, increases the transfer efficiency of machine barrel.
Machine barrel involved in the utility model is furnished with melt zone, since internal helicoid slot is long, it is contemplated that the side of processing
Just property, machine barrel melt zone can be made of segmental structure, and rear recombinant is in one.
Be disposed with the metal material layer of high abrasion on machine tube inner wall groove involved in the utility model, the wearing layer it is excellent
The abrasion for being to effectively reduce machine tube inner wall is put, the service life of machine barrel is extended.Wearing layer is using spraying or inlays or welds
Technique be process, wearing layer is connected firmly, and is not readily separated.
The cross sectional shape of spiral grooves involved by the utility model can be with rectangle, trapezoidal, triangle, arc-shaped etc., specifically
What, using shape, not determined by the shape size of the raw materials for plastics production of its production.Such as granulated raw material using rectangle or
Trapezoidal, powder shape raw material is using triangle or because of arc.
Detailed description of the invention
Attached drawing 1 is the machine barrel appearance schematic diagram of the utility model.
Attached drawing 2 is the cut-away view of the machine barrel of the utility model.
Attached drawing 3 is the trench cross-section schematic diagram of the machine barrel of the utility model.
Specific embodiment
Such as attached drawing 1, the utility model relates to machine barrel be made of flange 1, strong cooling section 2, spout 3, melt zone 4.
As attached drawing 2 the utility model relates to machine tube inner wall at least there are a spiral grooves 6, length can be grown as machine barrel,
It can also not determined according to the characteristic of plastic raw materials and required production efficiency mainly with 2 equal length of cooling section.
6 rotation direction of spiral grooves on the inside of the machine barrel of the utility model is oppositely oriented with the screw rod that matches.The spiral shell of groove 6
Revolving lead is that can design adjustment according to the size of machine barrel and required yield.Directly add in the inside of strong cooling section 2
Work has cooling duct 5, is passed through after cooling medium in channel 5, is convenient for direct heat exchange, can quickly take away plastic raw materials and machine
The extra heat that cylinder, butterfly, bar friction generate.The cooling medium can be water, gas or other liquid substances.Strong cooling section 2
Length is the characteristic according to plastic raw materials and designs, and at a suitable temperature, can increase the frictional force of raw material and machine barrel,
To realize the conveying of the high pressure of raw material, and fluctuation of the head pressure to conveying yield can be overcome.The design of spout 3 is adopted
With asymmetric eccentric structure, it is different from traditional symmetrical spout, is conducive to the feed quantity for improving raw material, increases
The transfer efficiency of machine barrel.Machine barrel is equipped with melt zone 4 since internal helicoid slot is long, it is contemplated that the convenience of processing, machine barrel are molten
