Abstract
The utility model discloses a melt pump for plastic product processing. The melt pump comprises a pump body, a screw rod, a heating device, an actuating device, and an electrical control device for controlling the rotating speed and the temperature of the melt pump, wherein the screw rod is arranged in the pump body; the screw rod is mutually meshed parallel double screw rods or tapered double screw rods; the heating device is an oil heating device or an electric heating device; the actuating device is a single-shaft actuating device or a double-shaft actuating device. The melt pump has the beneficial technical effects that after an extruding machine and the melt pump are in series connection, the pressure forming ability of the melt pump is used for achieving high head pressure meeting the pressure process requirements, so that the extruding machine and the melt pump unit can be combined with extrusion heads such as pipes, plates and films to directly extrude products, and through the application of the melt pump, the mixing quality of the material by the unit can also be greatly improved.
Description
Technical field
The utility model relates to a kind of Melt Pump, relates in particular to a kind of plastic article processing Melt Pump.
Background technique
In prior art, the upbuild voltage capacity of the extruder of mixing class is poor, except for extruding pelletization, generally, without its direct extruded product, can not meet people's requirement.
Model utility content
The purpose of this utility model is to provide a kind of plastic article processing Melt Pump, solves the shortcoming that prior art exists.
The utility model adopts following technological scheme to realize:
A kind of plastic article processing Melt Pump, it is characterized in that, comprise the pump housing, screw rod, heating equipment, drive transmission and for controlling the electric controller of Melt Pump rotating speed, temperature, described screw rod is arranged in the described pump housing, screw rod is intermeshing parallel double-screw or conical double-screw, and described heating equipment is oil heating unit or Electric heating appliance.
Further, described transmission device is single axle transmission or double-shaft transmission device.
Useful technique effect of the present utility model is: after extruder and Melt Pump are together in series, by the upbuild voltage capacity of Melt Pump, can reach the high head pressure of expressing technique requirement, so just the extruder heads such as extruder+Melt Pump unit and pipe, plate, film can be combined into production line, directly extruded product, application Melt Pump can also make unit significantly improve the mixing of material.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model Melt Pump.
Fig. 2 is the structural representation of the Melt Pump at another visual angle.
Embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but specific embodiment given claimant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characteristics change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
Plastic article processing Melt Pump as depicted in figs. 1 and 2, comprise the pump housing 1, screw rod 2, heating equipment, drive transmission and for controlling the electric controller of Melt Pump rotating speed, temperature, in the pump housing 1, there is a relatively closed space, can make screw rod 2 rotate therein, make the material of melting obtain pressurization, carry.Screw rod 2 is arranged in the pump housing 1, screw rod 2 is intermeshing parallel double-screw or conical double-screw, and screw rod 2 can produce high pressure in the time of rotation work, can overcome head resistance, make the material of melting stable, successfully extrude, parallel double-screw can also have larger conveying capacity.Speed, moment of torsion rotation work that drive transmission provides power that screw rod is needed by technique, heating equipment is oil heating unit or Electric heating appliance, transmission device is single axle transmission or double-shaft transmission device.Heating equipment, according to user or technique needs, can be oil heating or electric heating, makes Melt Pump and inner material reach the temperature of technological requirement.Electric controller carries out work for rotating speed, the temperature etc. of controlling Melt Pump by technological requirement.Screw rod Melt Pump main working process is: plastic raw material is through extruding, shearing and the heat effect of extruder, reach molten state, the material of melting enters in the pump housing from Melt Pump entrance, screw rod in Melt Pump rotates under the effect of drive unit and transmission device, thereby produce thrust forward, make melt produce positive conveyance, melt is extruded by head from Melt Pump outlet with stable pressure and stable flow.The plastics of extruding from head, keep the shape of machine head port mould to become goods (pipe, plate, film etc.) through cooling and shaping.Melt Pump has very strong supercharging voltage stabilizing ability, can overcome head resistance, thereby can shaping structure complexity, material viscosity is high, moulding difficulty is large goods.A little less than the shear action of incongruous double screw Melt Pump, in course of working, can not make like this material be sheared and degrade.Melt Pump also has the flow that provides stable, the function that improves melt plasticizing mixing, so the quality of goods also can significantly improve.
Compared with existing Melt Pump, the utility model adopts the pressurized delivered element that twin-screw is Melt Pump, and existing Melt Pump is that employing gear is pressurized delivered element mostly, and screw rod Melt Pump has advantages of that boosting capability is strong, conveying capacity is large, melting effect is good.Can improve plastic raw material mixed effect, improve plasticizing quality, improve output, energy saving, reduce costs, and strong to the applicability of various plastic raw materials.Because its inside is without dead angle, accurate to temperature of charge control, so be specially adapted to heat sensitive material.Connect with extruder by screw rod Melt Pump, can produce the original plastic article that cannot produce by extruder separately, as wide cut cast film, hard PVC sheet material etc., expanded like this extruder shaping operation raw material variety and goods kind.
On the basis of above-described embodiment, can also make further improvement: in the time of application conical double-screw, select specific conical double-screw, this conical double-screw is made up of feeding section, preformed section, fluxing zone, exhaust section and extruding zone, mixed block and fluxing zone are fixed on splined shaft, preformed section comprises leg-of-mutton mixed block, in mixed block, have mesh plate and boss, the outside cone angle that the outer rim of mesh plate forms is identical with the outside cone angle of screw rod; Rear portion at extruding zone is provided with mixing refining head.Improved like this benefit is: in the time that conical double screw extruder forwardtransfer signal worm rotates, due to the mixed block of preformed section, make material be subject to shear action between the outer rim of mixed block and machine barrel, be conducive to melting and the mixing of material, the mixed block of two screw rods engagement simultaneously, material enters another root screw rod from a screw rod, turnover each other in the mixed block between two screw rods, obtained further mixing, material can obtain mixing more fully in preformed section like this.
Certainly; the utility model can also have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
