Mother, nut coordinate with leading screw, and on servomotor, servomotor is fixed in frame leading screw；Charging hole is provided with piston plate,
Charging switch is equipped between charging hole and feed hopper, feed hopper is fixed on piston push rod, equipped with feed hopper above feed hopper
Lid；Flexible conveying pipeline is terminated with melt tank, the other end of flexible conveying pipeline is connected with shower nozzle, and shower nozzle upper end is equipped with flow control
Device.
The flexible conveying pipeline is respectively external protection coating, zone of heating, internal layer from outside to inside.
Compared with prior art, the utility model provides a kind of FDM types 3D printer melting consumptive material extrusion device, prints
Only have shower nozzle in journey to move along scanning track, the inertia in running can be reduced, flow-controlled device is added and can effectively control and ooze
Phenomenon is leaked, ensures surface of shaped parts quality.

Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment.
A kind of melting consumptive material extrusion device of FDM types 3D printer shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, including feeding mechanism, squeeze
Go out mechanism, frame 13；Feeding mechanism is made up of lid 8, charging switch 5 on feed pipe 7, feed hopper 9, feed hopper；Extrusion mechanism by
Shower nozzle 1, flow-controlled device 2, flexible conveying pipeline 3, piston plate 4, piston push rod 6, leading screw 10, nut 11, servomotor 12, melt tank
14 compositions；Melt tank 14 is fixed in frame 13, and the inner chamber of melt tank 14 is equipped with piston plate 4, and piston plate 4 is connected with piston push rod 6,
Nut 11 is housed, nut 11 coordinates with leading screw 10, and for leading screw 10 on servomotor 12, servomotor 12 is solid on piston push rod 6
It is scheduled in frame 13；Charging hole is provided with piston plate 4, charging switch 5 is equipped between charging hole and feed hopper 9, feed hopper 9 is fixed
On piston push rod 6, the top of feed hopper 9 is equipped with lid 8 on feed hopper；Flexible conveying pipeline 3 is terminated with melt tank 14, it is flexible
Conveying pipeline 3 is respectively external protection coating 31, zone of heating 32, internal layer 33 from outside to inside, the other end of flexible conveying pipeline 3 and shower nozzle 1
It is connected, the upper end of shower nozzle 1 is equipped with flow-controlled device 2.
During utility model works, charging switch 5 is opened, and graininess or powdered consumptive material enter feed hopper by feed pipe 7
9, then enter in melt tank 14 and heat by the charging hole on piston plate 4, after consumptive material is heated to molten condition, charging switch
5 close, and servomotor 12 drives leading screw 10 to rotate, and leading screw 10 coordinates with nut 11, and nut 11 is connected with piston push rod 6, then
The convert rotational motion of leading screw 10 is the linear motion of piston push rod 6, and piston push rod 6 moves down with piston plate 4, by molten consumption
