The edge camber line for strengthening material feeding push area is made up of the circular arc that one section of radius is 22mm, this section of arc diameter Chinese yeast
The big push ability of rate is strong, and material feeding ability is strong, is advantageous to conveying fan and realizes quick material feeding and set up the back pressure that material conveying needs;
It is wherein described it is flat transit back nip edge camber line major part be two sections of circular arcs before and after connection tangent line composition, by illustrating
It can be seen that the camber line in the region can provide to sizing material moves active force in opposite direction, amendment material movement side is played
To ensureing material uniformity, avoid material because occurring causing plastifying the problems such as conveying fan blocks too early, this section of tangent line is set
Meter has the function that to sizing material to the discrete conveying of circumferencial direction, avoids material from occurring causing to central shaft aggregation in course of conveying
The phenomenon that material is accumulated in plasticized screw the initial segment, the design in the region can be effectively improved the mobility status of material, improve
Applicability of the equipment to variety classes, characteristic material;The edge camber line for pushing area is made up of the circular arc that radius is 27mm, and it is designed
The uniform sequential entrance plasticized screw of material can be ensured;The reinforcing material feeding that arc flabellum is divided into pushes area, flat transition back pressure
Area and the push area of completion material conveying can make material produce the power promoted forward when conveying using such a camber line structure, make
Material to discharging direction transporting rate faster, and such a structure avoid material to flabellum revolving bed accumulate, be advantageous to screw rod and eat
Material.
Further to probe into the feed properties on this spiral blade face, and normal spiral blade (bipyramid cylinder spiral), i.e., without three sections
The curved surface of die joint, under equal conditions carry out contrast test;That is motor torque 0.5N/m, rotating speed 20r/min, this helical-blade
200 degree of face outlet temperature, 190 degree of normal spiral blade exit temperature, experiment shows, when flow velocity is increased to certain speed, goes out
Mouth temperature lifting range is little, and the technical barrier that normal spiral blade mainly faces is that the flow of extruded material is relatively low, general
There is 1cm3/ s, shaping efficiency and shaping speed are largely reduced, after the utility model uses this curved surface helical blade,
The flow of extruded material can reach 3cm3/ s, shaping efficiency and shaping speed are not only increased, and compared to normal spiral
Blade, feeding process is more stable, and pressure oscillation diminishes, and the stability increase of wire vent diameter, wire vent fluctuating error reduces.Using
This helical blade, its special surface can increase in feeding process to the shearing force of sizing material, make material in the work of different directions power
With lower stirring, compound viscosity is decreased, reduce resistance when it flows when promoting forward, mix sizing material more equal
It is even.
Above-mentioned 3D printing small-sized screw plasticizing apparatus comprises the following steps:
1. go out threedimensional model using Computerized three-dimensional Software on Drawing;
2. being cut into slices using Slice Software to threedimensional model, and then the information of part is generated, be then converted to computer
The instruction that can be identified;
3. after the completion of preparation, material is put by cover plate A again after heating a period of time in the presence of heat block first
Enter feed bin, the route formulated according to computer prints the product required for us.
Embodiments above is merely to illustrate and unrestricted the technical solution of the utility model.The utility model essence is not departed from
Any modification or partial replacement of god, all should cover among right of the present utility model.
