Description
Technical field
The present invention relates to extrusion molding equipment technology field, refer in particular to a kind of device that utilizes the planet smelt gear pump once to extrude a plurality of goods.
Background technology
Extrusion molding occupies very consequence in plastic product forming processing industry.According to statistics, in plastic product forming processing, the output of extrusion moulding product ranks first.With other forming methods relatively, extrusion molding has serialization production, productivity ratio height, be widely used the characteristics with smail investments and quick rerurn.Along with plastic extruding forming broad application and development, the type of extruder is increasing.
Extruder high speed, high yield can make the investor obtain the bigger output and the repayment of great number with lower input.Extruder efficiently be mainly reflected in high production, low energy consumption, low manufacturing cost aspect.In function aspects, screw extruder not only is used for the extrusion molding and the mixing processing of macromolecular material, and its purposes has been widened fields such as food, feed, electrode, explosive, building materials, packing, paper pulp, pottery.
At present, in order to improve shaping efficiency, the difficult point that extruder screw rotating speed high speed has also brought a series of needs to overcome: it is uneven that time of staying minimizing in screw rod can cause the mixing plasticizing of material as material, the excessive shear that stands material may cause hurried intensification of material and thermal decomposition, extrude stability control difficulty and can cause the fluctuation of extrudate physical dimension, the relevant servicing unit and the precision of control system must improve, the wearing and tearing of screw rod and machine barrel aggravation needs to adopt high abrasion and superelevation wear-resistant material, and how decelerator and bearing improve problem such as its life-span under situation about running up all need solution.
In the face of replacement of products the time, often face and utilize existing large-scale extruder to extrude the demand of the goods of small bore in the extrusion molding, at this moment, large-scale extruder is owing to turn round under the low speed situation, and rotating speed is not steady, and waste is serious.Also utilize an extruder to extrude two or more goods simultaneously at present, major part is only to extrude two goods, and reason is that two materials flows between goods influence each other seriously, if goods go wrong, another goods also can't normally carry out; One fluctuation occurs, and another also will be adjusted.And the more difficult realization of the goods that utilize an extruder to extrude different cross section simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of extrusion molding apparatus, utilize large-scale extruder to extrude a plurality of goods simultaneously, the production between each goods influences each other little, can make the goods of different cross section simultaneously.
Technical scheme of the present invention is, a kind of multiple products extrusion molding apparatus, mainly comprise extrusion system, the melt aggregating apparatus, the melt planetary gear pump, pump drive of melt planetary gear and control device, melt planetary gear pump temperature control equipment, branch's runner, affluent-dividing channel temp control device, head, extrusion system comprises one or more extruder, the inlet of melt aggregating apparatus is connected with the outlet of the melt of extrusion system, the melt aggregating apparatus will compile from the melt of one or more extruder, the melt aggregating apparatus has one or more inlets, the melt aggregating apparatus has an outlet, the outlet of melt aggregating apparatus is connected with melt planetary gear pump intake, flow through its temperature of melt of melt planetary gear pump temperature control equipment control, the rotation of pump drive of melt planetary gear and control device control melt planetary gear pump middle gear, regulate rotating speed, the flow of control melt, melt is divided into some branches and flows out from melt planetary gear pump discharge behind the melt planetary gear pump, each melt planetary gear pump discharge connects branch's runner, and each branch's runner is connected with head.Control the temperature of the melt of each branch's runner by affluent-dividing channel temp control system according to the mobility status of mouth mould place melt.
The extrusion system of a kind of multiple products extrusion molding apparatus of the present invention can be single screw extrusion machine, double screw extruder, multi-screw extruder, mill extruder, two-rotor continuous mixer, when extrusion system comprises many extruders, can be the combination of these extruders.
The melt planetary gear pump temperature control equipment of a kind of multiple products extrusion molding apparatus of the present invention add thermal recovery heating rod, heating collar or heater strip.
The heating of the runner temperature control system of a kind of multiple products extrusion molding apparatus of the present invention can be adopted heating rod, heating collar or heater strip.
The branch runner grouping back of a kind of multiple products extrusion molding apparatus of the present invention is connected with head, jointly to a head feed, is used to produce the different cross section shape and sectional dimension differs bigger goods by two or more branches runner.Cut-off equipment is set at it on by two or more branches runner branch's runner in groups, increases the controllability of complex section product molding.
The expressing technique process of a kind of multiple products extrusion molding apparatus of the present invention is: macromolecular material is after the loading hopper of extruder enters machine barrel, macromolecular material is plastifying under the effect of extruder temperature controller system and under the effect of the shearing force of screw rod rotation formation, the macromolecular material of fusing is that melt enters into the melt aggregating apparatus from the outlet of extruder outflow, melt enters into the melt planetary gear pump again through the melt aggregating apparatus, the melt that the melt planetary gear pump will compile is divided into uniform some branches, divide number to equal planetary number, each branch outlet of melt planetary gear pump connects branch's runner, melt enters in the head through branch's runner, again through typing, cooling obtains a plurality of goods simultaneously.According to the cross sectional shape of goods and the mobility status of melt, can control the temperature of the melt of each branch's runner by affluent-dividing channel temp control system, because the flow behavior of macromolecular material is very big to dependence on temperature.
The present invention is owing to having adopted melt planetary gear pump and the pump drive of melt planetary gear thereof and control device, melt planetary gear pump temperature control equipment, melt enters flowing of head and is not subjected to directly influencing of extrusion system, if when requiring extrusion system that high output is provided, can select many middle-size and small-size extruders feed simultaneously for use, reduce and made making and the application cost that large-scale extruder brings.Extrusion system also can be selected large-scale extruder, utilizes its bigger production capacity, obtains a plurality of goods simultaneously.Because planetary gear pump shunting precision height, the melt planetary gear pump evenly is divided into multiply with one materials flow, per share flow velocity and pressure are determined by corresponding planetary gear with it, as long as the melt planetary gear pump is working properly, branch's runner is not influence each other, one of them branch goes wrong or adjusts, and can not influence the ordinary production of other branches.Production efficiency improves greatly, and large-scale extrusion equipment has also obtained rational application simultaneously.
