In the technical scheme that this embodiment adopted, through the inlet pipe that sets up mounting groove 2 and installation, can follow two at least inlet pipes simultaneously and add the consumptive material for the heating piece, connector 3 has increased the distance between heating piece 1 and the print platform, and the heat dissipation is timely, has improved the printing quality, moreover, the utility model discloses the volume is less, simple structure, and the cost of manufacture is low, has further improved the speed that the 1 temperature of heating piece rises.
Preferably, heating block 1 is the rectangle, connector 3 is the cylinder, mounting groove 2 is the circular recess, inlet pipe and 2 threaded connection of mounting groove, nozzle 5 and the inner wall threaded connection who holds chamber 9, nozzle 5 is equipped with the external screw thread with the link that holds chamber 9, nozzle 5 is less than the cross sectional area of the 5 other ends of nozzle with the cross sectional area who holds chamber 9 link, the orientation of the 5 other ends of nozzle holds the side and the 3 butts of connector of chamber 9, it is cylindrical to hold chamber 9, mounting groove 2 is used for installing the inlet pipe, inlet pipe and 5 intercommunications of nozzle, a consumable conveying item. Wherein, the connector 3 and the mounting groove 2 are arranged on two opposite side surfaces of the heating block 1 so as to facilitate the transmission of the consumable. When in use, the consumable flows through the heating block 1, the connecting body 3 and the nozzle 5 in sequence through the feeding pipe.
Further, the printer head further comprises:
the feeding channel 4 is obliquely arranged at the bottom of the mounting groove 2, and the feeding channel 4 extends towards the direction close to the connecting body 3;
the mixing cavity 10 is arranged on the end face, close to the connector 3, of the heating block 1 and penetrates through the end face, one end of the mixing cavity 10 is communicated with the feeding channel 4, and the other end of the mixing cavity is communicated with the discharging channel arranged in the nozzle 5.
In the technical scheme that this embodiment adopted, the slope of feedstock channel 4 sets up the jam that can prevent the consumptive material, from the consumptive material that the inlet pipe added, after the heating of heating piece 1, flows in the compounding chamber 10 by feedstock channel 4 and carries out the compounding, and the back is accomplished to the colour mixture, extrudees by nozzle 5 and flows to realize the printing effect of colour mixture. Meanwhile, the mixing cavity 10 is arranged at the end face close to the connecting body 3, so that all consumables entering the mixing cavity 10 can be melted. Specifically, the cross-sectional area of the mixing cavity 10 is smaller than that of the accommodating cavity 9, so that the nozzle 5 and the mixing cavity 10 can be tightly connected, and melted consumables can completely flow into the nozzle 5; the cross-sectional area of feed channel 4 is less than the cross-sectional area of mixing chamber 10, can slow down the inflow speed of consumptive material, realizes the homogeneity of colour mixture.
Further, the horizontal cross-sectional area of the discharging channel is larger than, equal to or smaller than the horizontal cross-sectional area of the mixing cavity 10.
In the technical scheme that this embodiment adopted, in order to make the consumptive material that flows out from compounding chamber 10, can get into discharging channel completely, the preferred sectional area who sets discharging channel to be more than or equal to compounding chamber 10 with discharging channel's sectional area, avoid collecting up the consumptive material in the junction of nozzle 5 and compounding chamber 10, thereby less avoid the waste of consumptive material, the cost is reduced, and simultaneously, guaranteed the continuity of consumptive material when the inflow discharging channel, improved printing quality. Certainly, the sectional area of the discharge channel is set to be smaller than that of the mixing cavity 10, so that the inflow speed of consumables can be reduced, and the uniformity of color mixing is realized.
Further, the connector 3 and the heating block 1 are manufactured by an integral molding process.
In the technical scheme adopted by the embodiment, the integrated forming process is simple to manufacture, low in cost and easy to realize.
Further, the connecting body 3 is arranged at one end of one end face of the heating block 1, and the other end of one end face of the heating block 1 inclines towards the other end face of the heating block 1 to form an inclined plane;
