Abstract
The utility model discloses a disc extruder for high-filled and highly dispersed materials. A fixed disc(5) is fixed on the extrusion cylinder(4) and die(11) and a dynamic disc(6) is serially connected with other components and driven by a driving device(12). The fixed disc(5), dynamic disc(6) and a transition block(7) form into a mixing unit, which is installed together by means of cordwood using gaskets(13) to adjust relative gap between the fixed disc(5) and the dynamic disc(6), which are carved with groove patterns. Through relative rotation of patterns, the processed materials are continuously and repeatedly compressed, extended, distributed and accumulated which exchanges positions of materials and accomplishes the whole process of mixing and distributing. A plurality of mixing units can be serially connected to improve mixing effect.
Description
(1) technical field
The utility model relates to a kind of high mixing plastic, rubber processing mechanical apparatus---disc type extruder, is specially adapted to raw material manufacture fields such as magnetic plastics, rubber, rubber plastic blend, high filling, nano-dispersed.
(2) background technology
Traditional rubber plastic disperses mixing apparatus to mainly contain several basic equipment forms such as high-speed stirring mixer (being called for short height stirs), open type plastic purificating set (abbreviation mill), banbury and screw-type extruder.Wherein the most widely used is the screw-type extruder kind equipment, the normally used single screw extrusion machine that mostly is.Along with raising to the mixing requirement of raw material, develop into double screw extruder even three-screw extruder or multi-screw extruder etc., that generally uses in functional rubber-plastics material granulation industry at present mostly is the parallel type double screw extruder.The operation principle of screw-type extruder is the mixing effect of (twin-screw) generation shearing between (single screw rod) or spiral shell rib and the spiral shell rib between the spiral shell rib that relies on screw rod rotate in machine barrel to produce and the machine barrel, because the active area of its shearing is less, when having strong shearing to require, material just has only with improving rotating speed to increase shear effect.But the method for this simple rev up can occur generating heat too high in process of production and shear drawbacks such as excessive, thereby can cause the oxidation Decomposition even the carbonization of raw material and additive.In addition, along with the increase of the development of rubber industry and functional material and every field to goods property demand, the mixing behavior of pure screw-type extruder does not reach the dispersion mixing requirement to material far away, particularly in process, use double screw extruder that the excessive and situations such as initiating failure of screw rod torque often take place to high fill material.Especially when nano material is carried out dispersion treatment, because it disperses shearing force not enough, can not open nanometer bulk structure, and then material do not reach nano level dispersion level, directly influenced the performance quality of product.Therefore need a kind of running speed lower and high fill material of suitable processing and novel processing equipment in the industry with high dispersive characteristic.
(3) utility model content
The continuous mixing production equipment that the purpose of this utility model is to provide the high rubber and plastic raw material of filling of a kind of suitable processing and the high dispersive effect can be provided.
The purpose of this utility model realizes by following measure:
1. use price fixing, Moving plate and the transition spiral shell piece have sipe to form mixing unit, the use of can connecting of mixing as required unit.Price fixing by bolt series connection and with the machine barrel transfixion that is fixed as one; Moving plate is connected rotation with associated components, the gap of material between Moving plate and price fixing passed through, and is transported to next mixing unit to increase melting effect through transition spiral shell piece again.Because the decorative pattern difference of each mixing dish, the melting effect that reaches are also different.
2. the gap between price fixing and the Moving plate can be adjusted by pad, with the size of control shearing force.
3. cooling chamber is set in price fixing, at price fixing and machine barrel outer surface heating collar is set, corresponding cooling chamber and heating collar are formed independently temperature control system.
The disc type extruder of the utility model, make and shear on the face that occurs between dish and the dish, thereby increased material and sheared mixing area, improved the shearing dispersion effect, can under lower rotating speed, process again simultaneously, reduce the harmful effect that the irrationality because of mechanical processing process causes to goods to greatest extent.This equipment has also designed multiple sipe on price fixing and Moving plate, can be equipped with by multiple combination according to the difference of material to be machined, makes material occurrence positions exchange in mixing process, has improved the dispersiveness of high fill material greatly.

(5) specific embodiment
Head (11), machine barrel (4) and price fixing (5) are connected and fixed, and conveying screw rod (10), exhaust spiral shell piece (9), Moving plate (6), transition spiral shell piece (7) and reinforced screw rod (2) are coupled as one to link with drive unit (12).Wherein price fixing (5), Moving plate (6) and transition spiral shell piece (7) are formed mixing unit.In mixing unit, install pad (13) additional.
The reinforced screw rod (2) of drive unit (12) drive, Moving plate (6), transition spiral shell piece (7), exhaust spiral shell piece (9), conveying screw rod elements such as (10) rotate together.Continue mixingly when material takes place to be transported to the mixing unit of next stage through transition spiral shell piece (7) after mixing through by the price fixing (5) of heating collar (3) heating, Moving plate (6) time in the gap, the material that mixes discharges gas through exhaust spiral shell piece (9) after conveying screw rod (10) carries pressurization to extrude through head (11).
The utility model uses dosing device (1), in the reinforced screw rod of sending into of material dosing (2), is delivered in the mixing unit through preliminary the thawing.Dosing device (1) can be the screw dosing unit, also can be electronic measuring scale.
Mixing unit is installed with modular construction, can be used on single screw rod also to can be used on the multiscrew.In process, the relative motion by the rollet on price fixing (5) and the Moving plate (6) makes material to be machined constantly be compressed, stretch, shunt, assemble, thereby and goes round and begins again and finish overall process mixing and that disperse.Price fixing is different according to the requirement of processed raw material with sipe on the Moving plate, can from the sipe type shown in the accompanying drawing 3～8, select, such as the rotating knife shape of the mouth as one speaks (Fig. 3), fan type (Fig. 4), chrysanthemum type (Fig. 5), square type (Fig. 6), stripe shape (Fig. 7), millstone type (Fig. 8) etc.Also can be designed to other shape according to specific requirement.
