The main feeding capacity is controlled by the variable frequency speed control of the rotary speed of the main threaded rods, and the variable frequency speed control is synchronously carried out according to the rotary speed of the auxiliary threaded rods at the bottom to achieve the optimum balance control with the output of the main threaded rods.
Description
Technical field
The present invention relates to a kind of feeding machine that is widely used in industries such as metallurgy, mine, building materials, chemical industry, the present invention relates to a kind of plastics mixed volume metering feeding system more precisely.Belong to the chemical machinery technical field.
Background technology
General plastics mixed volume metering feeding machine, feed screw is adjustable speed twin-screw or single screw rod, barrel top opening connects up big and down small tapered or special-shaped hopper, disposes agitator in the hopper or disposes beater outward.In powder and pellet mixing feeding course of conveying, exist the different combined cause of specific gravity difference, content ratio and mobile performance of powder and pellet.Because the imperfection of feed system, in feeding procedure, stirred or the means of vibration very easily produce the conveying lamination of material.The viscosity of powder very easily produces again and builds bridge in the material, and in the mixing extruder granulation process, every performance indications of finished product particle (for example: hot strength, elongation at break etc.) are extremely unstable.
Summary of the invention
The purpose of this invention is to provide a kind of can make powder and pellet in dropping process, form the layer all fall, avoid the mixture of powder and pellet in the feeding course of conveying, to produce layering and arch formation.
The present invention takes following technical scheme to realize:
Multi screw stem material feeding machine comprises driving screw, reducing motor and hopper, it is characterized in that wherein said hopper is a lateral vertical moulding mixture bucket, and also comprises sub-screw; Described driving screw is positioned at the below of sub-screw and forms vertically and with reducing motor mutually and is connected; Described sub-screw is connected with another reducing motor, and sub-screw all is that therefrom portion separates positive antispin direction; Driving screw and sub-screw are installed in the bottom of hopper.
Aforesaid multi screw stem material feeding machine is characterized in that wherein said sub-screw has 6 at least.
Aforesaid multi screw stem material feeding machine is characterized in that wherein said hopper is a multi-edge column-shaped or columniform.
Aforesaid multi screw stem material feeding machine is characterized in that wherein said hopper is a four prism type.
Aforesaid multi screw stem material feeding machine is characterized in that wherein said sub-screw is 10.
Multi screw stem material feeding machine of the present invention is in powder and pellet blend feeding course of conveying, and the special construction of multi screw stem material feeding machine forms layer homogeneous and falls, and effectively avoids the mixture of powder and pellet to produce layering and arch formation in the feeding course of conveying.
Multi screw stem material feeding machine hopper four sides lateral vertical is a square type, and the bottom is that sub-screw (three～eight pairs of sub-screw engagement types) is carried to the center from left and right directions, and core is a pair of driving screw engagement type conveying screw rod and sub-screw horizontal vertical.Main feeding capacity is controlled in the frequency control of driving screw rotating speed.Bottom sub-screw synchronization frequency control reaches optimum balance control with the driving screw load.
Description of drawings
Fig. 1 is the left TV structure figure of multi screw stem material feeding machine of the present invention;
Fig. 2 is the right TV structure figure of multi screw stem material feeding machine of the present invention;
Fig. 3 is the plan structure figure of multi screw stem material feeding machine of the present invention.
The specific embodiment:
Multi screw stem material feeding machine as Figure 1-3, wherein hopper (1), sub-screw (2), driving screw (3), travelling gear (4), reducing motor (5), support (6);
(1), utilize multi screw stem material feeding machine of the present invention to come to be the low smoke halogen-free fire retardant polyolefin cable material mixing granulator:
1, the technological process of production: polyolefin pellets LLDPE and EVA, fire retardant powder Al (OH) 3 and Mg (OH) 2,28: 65: 7 in proportion → input of auxiliary agent high mixer mix stirring → mixed material by multi screw stem material feeding machine metering feeding conveying → mixing extruder → pelletizing finished product.
2, multi screw stem material feeding machine operation principle and technical parameter:
Mixed material is sent into the square hopper of four lateral vertical after high mixer mix to stir, because hopper four limit vertical smooth, inner chamber, volume are bigger, and do not have the inclined-plane cambered surface can rely on material.So material directly presses volt on the sub-screw of feed hopper bottom, every sub-screw all is that therefrom portion separates positive antispin direction, and material moves to sub-screw center line direction when sub-screw rotates.The 8-12 root rotates and the sub-screw of the reverse engagement of helicla flute synchronously side by side on the sub-screw horizontal line, and the effect of Meshing Pair screw rod is mixed material displacement conveying can not produced pellet and powder carry uneven phenomenon.So mixed material lies prostrate in feed hopper bottom to evenly pressing layer by layer down in hopper, the mixed material that enters the multiscrew screw channel forms the bottom surface and evenly moves to the middle part, sub-screw middle part parallel beneath vertical direction is close to and is being covered a pair of main twin-screw that meshes in the same way, and mixed material falls into main twin-screw and is measured and transfers out multi screw stem material feeding machine like this.So material does not have dead angle, uniform and stable when conveying is mobile.The speed of material translational speed is exactly the size of feeding capacity, speed control is power to be transformed on the every sub-screw synchronously by the main drive gear on the transmission screw rod through frequency control by a reducing motor, material is just evenly shifted to midline position, in the driving screw groove of the constant speed running below footpath, the end of sub-screw and sub-screw gap location falls into, at this moment material can be admitted in the main frame machine barrel apace, because the constant speed driving screw usually is in the middling speed starvation, its conveying capacity is all the time greater than the amount of sending into of sub-screw, thus material just can not produce do not roll, adverse current.Whole transportation process does not have pressure, breaks away from layer by layer, makes the material in the magazine finish feeding under static relatively state.Thereby solved the lamination of mixed material in feeding procedure.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within protection scope of the present invention.
