Abstract
The invention relates to a novel polyolefin pipe-based basket type machine head. The machine head comprises a die cavity, a die body, a die core and heaters, wherein the die cavity and the die body are connected in sequence to form a housing; the die core is arranged into the housing to form an inner core; a melt cavity is formed between the inner core and the housing; and the heaters are arranged on the outer surface of the housing and an inside arm of the inner core. Compared with the prior art, the novel polyolefin pipe-based basket type machine head has the advantages of being wide in range of application, long in service life, simple and accurate in operation, high and stable in output and accurate in melting temperature control, and also can save the energy and reduce the consumption.
Description
Technical field
The present invention relates to a kind of polyolefin pipe head, especially relate to a kind of polyolefin pipe blanket-type head.
Background technology
Basket head is because the huge aisle spare of basket only has very low loss of total pressure in the die head, and hear rate is is seldom scattered and disappeared, and this low pressure, heat-energy losses have been brought higher output, lower energy consumption, higher-quality goods.The domestic producer that can not produce basket head, this kind equipment is basically take import as main.My company is domestic first man study digestion advanced foreign technology, the company that develops serial polyolefin pipe blanket-type head.
Summary of the invention
Purpose of the present invention does not domesticly have in order to provide a kind of, the scope of application extensively, the series type polyolefin pipe blanket-type head of long service life.
Purpose of the present invention can be achieved through the following technical solutions:
The basket head of a kind of new type polyolefin tubing, comprise die cavity, die body, core rod and heater, described die cavity and die body connect and compose shell successively, described core rod is established and is formed in the enclosure inner core, form melt flow channel between inner core and the shell, described heater is located on the inwall of the outer surface of shell and inner core.
Material is heated to that the opening by the adapter assembly input enters the die body assembly after the glutinous stream mode, through the pipe embryo that has the ring section shape behind die body assembly and the basket and through a mouthful mould, mandrel molding.
Described die cavity is connected through bolt with die body.
The junction of described die body and core rod arranges basket.
Described core rod is the core of hollow, is connected and composed successively by two core rod assemblies.
Described melt flow channel all adopts the evanohm steel manufacturing of surface sclerosis and modifier treatment.
The top of described die body is connected with the head adapter through bolt.
Described head adapter is connected with main frame.
Compared with prior art, the present invention has the following advantages:
One, the scope of application is wide: the basket head of this new type polyolefin tubing has plurality of specifications, is applicable to the polyolefin pipe production line of diameter range φ 16～φ 2400mm.
Two, long service life: specially designed die body runner has guaranteed the service life of head.
Three, simple to operate accurate: the simplification and the accuracy that in design process, just fully take into account operation.Bolt is convenient to each section of pipe die head and is assembled quickly and accurately.The die head dolly can conveniently be realized the Accurate align between die head and the production line.
Four, simple to operate accurate: the simplification and the accuracy that in design process, just fully take into account operation.Bolt is convenient to each section of pipe die head and is assembled quickly and accurately.The die head car can conveniently be realized the Accurate align between die head and the production line.
Five, output is high and stable: this design make polyolefin pipe produce in melt homogenizing more; The load that material is subject to is little, and temperature of charge is low, improves extrusion capacity; Stability is high, in the variation of tubing caliber and wall thickness, under the variation of polyolefin raw material model, material viscosity, back pressure, can both produce high-quality tubing.
Six, molten temperature control is accurate: adopt the heating collar of independent control to guarantee the accuracy of each bringing-up section temperature on the die head.
Seven, energy-saving and cost-reducing: the temperature control of die head core automatic heating is regulated the tube wall thickness fluctuation is minimized, to reach the purpose of conservation.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is that primary heater, 2 is that the second core rod, 3 is that secondary heater, 4 is that the second die cavity, 5 is that the first core rod, 6 is that basket, 7 is that the 3rd heater, 8 is that the first die cavity, 9 is that die body, 10 is the head adapter among the figure.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
The basket head of a kind of new type polyolefin tubing, its structure comprise primary heater 1, the second core rod 2, secondary heater 3, the second die cavity 4, the first core rod 5, basket 6, the 3rd heater 7, the first die cavity 8 and die body 9 as shown in Figure 1.Die body 9, the first die cavity 8 and the second die cavity 4 connect and compose the shell of head successively.The first core rod 5 and the second core rod 2 connect and compose inner core successively, and inner core is positioned at above-mentioned shell, and and shell between form melt flow channel, this melt flow channel all adopts the evanohm steel manufacturing of surface sclerosis and modifier treatment.Be provided with secondary heater 3 and the 3rd heater 7 at the die cavity outer surface.The second core rod 2 is the hollow core, and wall is provided with primary heater 1, the second core rod 2 and links to each other with the first core rod 5, die body 9 by bolt within it, and the junction also is provided with basket 6.The end face of die body 9 is connected with head adapter 10 through bolt, and head adapter 10 links to each other with extruder.
During use, polyolefin pipe blanket-type head links to each other with extruder adapter 10, the fused materials that extruder is extruded flows into polyolefin pipe blanket-type head by head adapter 10, through the pipe embryo that also has the ring section shape through a mouthful mould, mandrel molding behind die body assembly and the basket 6.In the basket section, twice change of melt material flow flows to, then become axially, and mixing that can be good between the sub-thread material stream, melt is homogenizing more.Adjust primary heater 1 and add secondary heater 3 change melts temperature in head according to pipe embryo situation.
The specification of this serial basket tubing head has:
