Abstract
The utility model discloses an inside-outside annular heating type plastic extruder, which comprises a mold outlet (1), an outer annular wall (2), an inner annular wall (3) and a screw (6). The screw (6) is arranged inside the inner annular wall (3) which is positioned inside the outer annular wall (2), and the outer annular wall (2) and the inner annular wall (3) form a liquid storage heating container. The extruder is characterized in that heat conducting liquid is filled in the heating container, a heat conductor body (4) is arranged inside the container, and the screw (6) is internally hollow and filled with the heat conducting liquid, and a heat conductor body (42) is arranged in the hollow body, an electric conducting wire (51) is externally connected to the heat conductor body (42). The heat conductor body arranged inside the hollow screw heats up the screw to uniformly heat plastisol, thereby reducing inside-outside temperature difference of the plastisol, guaranteeing temperature of the plastisol, reducing friction force between the plastisol and the screw, and increasing extrusion force of plastics.
Description
Technical field
The utility model relates to plastic extruder, relate in particular to a kind of can inside and outside simultaneously the heating plastic extruder.
Background technology
Traditional plastic extruder all is to heat in the outside of sleeve, the plastisol heating surface area only limits to the area of the inwall of sleeve, plastisol inside then is not transmitted to heat, make being heated of colloidal sol inhomogeneous, influence the speed and the quality of extrusion molding, disclose the patent No. at present and be 96201940.2 plastics extruding machine technology, it just carries out heat treated at the extruding machine outer sleeve to plastisol, the mode of handling be heat conduction also, its heat conduction position electricity heat conduction.Though this extruding machine effectively heats plastisol, its heat conduction source is single, and plastisol can't comprehensively be heated, the internal-external temperature difference Shanghai Communications University, the inner frictional force with screw rod of colloidal sol is strengthened, well do not play quick adding, accelerate the effect of extrusion molding amount.
The utility model content
The technical problems to be solved in the utility model provides a kind of extrusion moulding apparatus that is provided with heat carrier in screw rod inside, can more fully heat plastisol.
For solving the problems of the technologies described above, the utility model has the die orifice of going out, external annulus, internal ring wall and screw rod, wherein screw rod is in internal ring wall, internal ring wall is in external annulus, external annulus and internal ring wall are formed the dress liquid heating vessels, in the described heating container conductive fluid is housed, be provided with heat carrier in the container, described screw rod inside is hollow body, in be filled with conductive fluid, and heat carrier is set in hollow, heat carrier is circumscribed with conductor wire, and after the energising, heat carrier begins heating, and the temperature that is filled in the conductive fluid of screw rod in hollow is raise, the temperature of whole screw rod is raise, the plastisol in the screw sleeve is heated, the heat carrier in the container can be arranged around heating container, but also symmetric arrangement, the external conductor wire of heat carrier.
The utility model is provided with heat carrier in screw rod is hollow, screw rod is heated, and plastisol is heated evenly, and reduces the plastisol internal-external temperature difference, guarantees the temperature of colloidal sol, and reduces the frictional force between plastisol and the screw rod, increases the extrusion pressure of plastics.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this extruding machine comprises die orifice 1, external annulus 2, internal ring wall 3 and screw rod 6, wherein screw rod 6 is in internal ring wall 2, and internal ring wall 3 is in external annulus 2, and external annulus 2 is formed the dress liquid heating vessels with internal ring wall 3, in the described heating container conductive fluid is housed, be provided with heat carrier 4 in the container, described screw rod 6 inside are hollow body, in be filled with conductive fluid, and heat carrier 42 is set in hollow, heat carrier 42 is circumscribed with conductor wire 51.Heat carrier 4 in the container can arrange around heating container, but also symmetric arrangement, the external conductor wire 5 of heat carrier.After the energising, heat carrier 42 in the screw rod begins heating, and the temperature that is filled in the conductive fluid of screw rod in hollow is raise, the temperature of whole screw rod 6 is raise, plastisol in the screw sleeve is heated, plastisol is heated evenly, reduce the plastisol internal-external temperature difference, guarantee the temperature of colloidal sol, and reduce the frictional force between plastisol and the screw rod 6.
Claims (2)
1. inner and outer ring hot type plastic extruder, comprise die orifice (1), external annulus (2), internal ring wall (3) and screw rod (6), wherein screw rod (6) is in internal ring wall (2), internal ring wall (3) is in external annulus (2), external annulus (2) is formed the dress liquid heating vessels with internal ring wall (3), it is characterized in that: in the described heating container conductive fluid is housed, be provided with heat carrier (4) in the container, described screw rod (6) inside is hollow body, in be filled with conductive fluid, and heat carrier (42) is set in hollow, heat carrier (42) is circumscribed with conductor wire (51).
2. a kind of inner and outer ring hot type plastic extruder according to claim 1 is characterized in that: the heat carrier (4) in the described container can arrange around heating container, but also symmetric arrangement, the external conductor wire of heat carrier (5).
