Extrusion wheel 164 of the seat 161 away from 163 side of compression spring；Pedestal 11 is fixed in one end of compression spring 163, the other end promotes
Bearing seat 161 is axis rotation with shaft 162, extrusion wheel 164 is turned to the position close to charging gear 14, feeds gear 14
Clamping action is played with extrusion 164 pairs of raw material of wheel, it is necessary to when being printed to product, and the driving driving of motor 13 feeds gear 14
Rotate, feed the frictional force between gear 14 and raw material and drive raw material movement, and extruder head 2 is transmitted to by feed pipe 15
It is interior, while compress spring 163 and cushioning effect is played to extrusion wheel 164, make extrusion wheel 164 be not easy to cause to damage to raw material, stir
Mix and be recessed inwardly in the middle part of 52 outlets of wheel, recess is slided for raw material and inlay card, and the inlay card effect for the raw material that are recessed makes
Raw material are less prone to offset, and the movement that raw material stablize is driven beneficial to charging gear 14, and by feed pipe 15 by raw material
It is transmitted in extruder head 2.
As shown in figures 1 and 3, the one end of feed pipe 15 away from pedestal 11 is communicated in extruder head 2, is provided with extruder head 2
Heat-generating pipe 3, the raw material being sent in extruder head 2 are gradually melted by the heat effect of heat-generating pipe 3, and are in colloidal state or liquid
State, the raw material after thawing print product easy to discharge extruder head 2, and heat-generating pipe 3 is installed on extruder head 2 in a ring
Interior, the heat-generating pipe 3 that annular is set is beneficial to uniformly heat the raw material everywhere in extruder head 2, and raw material pass through feed pipe 15
Persistently it is sent in extruder head 2 and after raw material thawing, there is a situation where raw material are back to feed pipe 15, Jin Erzao
The problem of being blocked into extruder head 2, the workload that staff frequently clears up extruder head 2 is larger, therefore, in feed pipe 15
One end outer cover for being communicated in extruder head 2 is equipped with heat sink 4, and heat sink 4 plays cooling effect to feed pipe 15 so that feed pipe
The temperature of 15 2 one end of connection extruder head is relatively low, and it is fast in the relatively low feed pipe 15 of temperature to be back to the raw material in feed pipe 15
Rapid hardening is consolidated, and effectively prevents the situation that raw material flow back from occurring, and reduces the workload that staff clears up extruder head 2.
Heat sink 4 is in lattice-shaped, and makes heat sink 4 and the surface area of external contact larger, and heat dissipation effect is more preferable, extruder head
2 outside is provided with the mounting bracket 7 for playing the role of carrying to extruder head 2；It is provided with towards the connection of feed pipe 15 and squeezes on mounting bracket 7
Lift one's head the radiator fan 6 of 2 one end blowing, cooling effect of the radiator fan 6 to feed pipe 15 further prevent raw material from occurring back
Flow, offer relieve heat hole on mounting bracket 7, relieve heat hole can effectively lift the air circulation effect in mounting bracket 7, and feed pipe 15 is by iron
Teflon tube material is made, and since the friction coefficient of Teflon is relatively low, and makes Teflon pipe easy to be transmitted to raw material.
Mixing component 5 includes：Stirring motor 51；And it is installed on 51 output shaft of stirring motor and is placed in extruder head 2
Interior stirring wheel 52, driving motor 13 drive stirring wheel 52 to rotate, raw material of the stirring wheel 52 to the multiple color in extruder head 2
It is stirred, and a variety of raw material is stirred so that the product color printed is more abundant, the periphery of stirring wheel 52
Circle is equipped with some blades 53 being obliquely installed, and when stirring wheel 52 rotates, the setting of blade 53 further carries out a variety of raw material
Stirring so that a variety of raw material are stirred more uniform, and since blade 53 is obliquely installed, and have when rotating to raw material
There is downward motive force, extruder head 2 is discharged beneficial to raw material.
The course of work and principle：The raw material of different colours are equipped with multiple feed devices 1 respectively, multiple color
Raw material are transferred in extruder head 2, and heat-generating pipe 3 heats extruder head 2 and melts solid state feed stock in extruder head 2 to be
The raw material of multiple color are uniformly mixed by colloidal state or liquid, mixing component 5, extruded first 2 discharge of the raw material by stirring
And product is printed, when the raw material in extruder head 2 are more, easily lead to raw material and flow backwards in feed device 1,
In turn result in extruder head 2 to block, one end that heat sink 4 connects feed device 1 extruder head 2 is radiated, and temperature is reduced and made
The raw material quick solidification flow backwards must occur, and then prevent refluence, raw material is smoothly discharged by extruder head 2, it is and normal
The 3D printer seen is compared, and is transmitted in raw material to extruder head 2 and is mixed by multiple feed devices 1, and makes to print
The product color come is more abundant and beautiful.
