Abstract
The utility model discloses a threaded rod for extrusion molding of polystyrene. The threaded rod comprises a fixed end, fixed rods and threaded rod components, wherein the fixed end is driven by a motor to rotate; at least two fixed rods are fixedly arranged on the fixed end; and each of a plurality of threaded rod components is provided with an assembly hole matched with the fixed rod. The threaded rod for extrusion molding of polystyrene is of a split structure; when part of the threaded rod is worn, only fittings at the worn part need to be replaced, so that the production cost for the extrusion molding of polystyrene is reduced.
Description
Technical field
The utility model relates to a kind of polystyrene extruded plastic screw rod, belongs to polystyrene material processing technical field.
Background technology
In prior art, polystyrene extruded plastic screw rod is generally overall structure, and polystyrene extruded plastic screw rod is divided into multistage, and every section has no function, and long-term work meeting is worn the surface of screw rod; Integrally-built screw rod, wearing and tearing occur a part will cause disappearance or the hydraulic performance decline of a certain function of screw rod, thereby affects the quality of polystyrene extruded plastic product, therefore needs to change whole screw rod, makes polystyrene extruded plastic production cost higher.
Summary of the invention
The deficiency that the utility model exists for prior art just, provides a kind of polystyrene extruded plastic screw rod, is Split type structure, when wearing and tearing occur a part, only needs to change the accessory of abrading section, thereby reduces polystyrene extruded plastic production cost.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of polystyrene extruded plastic screw rod, comprise: stiff end, fixed bar, screw arbor assembly, described stiff end is rotated by driven by motor, described fixed bar is at least two and be fixedly arranged on described stiff end, described screw arbor assembly is multiple, and each described screw arbor assembly is provided with the assembly hole matching with described fixed bar.
As the improvement of technique scheme, described polystyrene extruded plastic screw rod also comprises and adds fixed end, and described fixed bar one end is fixedly arranged on described stiff end, described in the other end connects, adds fixed end, described in add fixed end and rotated by driven by motor.
As the improvement of technique scheme, described screw arbor assembly is three, and is respectively melting screw rod, batch mixing screw rod, extrusion screw rod.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Polystyrene extruded plastic screw rod described in the utility model is Split type structure, when wearing and tearing occur a part, only needs to change the accessory of abrading section, thereby reduces polystyrene extruded plastic production cost.
Accompanying drawing explanation
Fig. 1 is polystyrene extruded plastic screw-rod structure schematic diagram described in the utility model;
Fig. 2 is stiff end structural representation described in the utility model.
The specific embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As depicted in figs. 1 and 2, be polystyrene extruded plastic screw-rod structure schematic diagram described in the utility model.Polystyrene extruded plastic screw rod described in the utility model, comprise: stiff end 1, fixed bar 2, screw arbor assembly, described stiff end 1 is rotated by driven by motor, described fixed bar 2 is at least two and be fixedly arranged on described stiff end 1, described screw arbor assembly is multiple, and each described screw arbor assembly is provided with the assembly hole matching with described fixed bar 2.Particularly, described fixed bar 2 is 3 to 5, is uniformly distributed in the disc edge with described stiff end 1 concentric.Also comprise and add fixed end 3, described fixed bar 2 one end are fixedly arranged on described stiff end 1, described in the other end connects, add fixed end 3, described in add fixed end 3 and rotated by driven by motor.Described fixed bar 2 two ends are jointly stressed, contribute to reduce the twisting resistance that described fixed bar 2 bears, and especially reduced the power of bearing of described fixed bar 2 away from one end of described stiff end 1.Particularly, described screw arbor assembly is three, and is respectively melting screw rod 4, batch mixing screw rod 5, extrusion screw rod 6.Described screw arbor assembly quantity too much can make the mass formation larger fluctuation of extruded product, the screw rod of each function is arranged to a screw arbor assembly to be verified by actual production, comparatively rational, respectively and set gradually melting screw rod 4, batch mixing screw rod 5, extrusion screw rod 6 and can meet the needs that polystyrene extruded plastic is produced.
Above content is the detailed description of in conjunction with specific embodiments the utility model being done, and can not assert that the concrete enforcement of the utility model only limits to these explanations.For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
