Description
Technical field
The present invention relates to a kind of pair of shower nozzle 3D printer feeding stiffening device and feed device, belong to 3D printing field.
Background technology
3D printing, also known as increasing material manufacturing, belongs to one kind of rapid shaping technique.3D printing technique came across for 20th century 80 years
Generation, but due to cost recent years just more and more used.The principle of the 3D printing technique of fused glass pellet：
Thread heat-fusible materials are carried out into heating and melting, material is extruded by the extruder with minute nozzle.Shower nozzle can be with
Moved along Y-axis and Z-direction, workbench then along X-axis direction move, the silk material of melting be extruded after immediately can with it is previous
Layer material is bonded together.Layer of material deposition aftertable will press predetermined increment and rise a thickness, then repeat more than
The step of be molded completely until workpiece.
3D printer silk material is to send into 3D printer by the feed device of the 3D printer of fused glass pellet type to spray
The heating part of head.The extruded velocity of melting silk material raw material is determined due to the feeding speed of feed device, so feed device
It is a very important part of the 3D printer machining accuracy for ensureing fused glass pellet type.What is commonly used at present send
Material device is made up of motor internal, internal wire feed rolls, internal bearings and contained spring, operationally, internal bearings internally bullet
Silk is pressed on internal wire feed rolls under the active force of spring, internally motor rotate under, silk with internal wire feed rolls rotation
Move up and down.But this device has its own shortcomings：One is that wear phenomenon occurs in feed device after working long hours, and can be led
The problem that silk is skidded, extrusion pressure is uneven is caused, causes printing precision to reduce；Two is that existing feed device is to ensure
Wire feed precision, the feed inlet and outlet bore design of device is smaller, but in practice, the heated after-tack expansion of silk, can cause into
To be bonded at charging aperture wire feed not smooth for silk during material, and silk is stuck in charging aperture to move back silk slow during the material returned.Three is existing feed device meeting
Occurs the phenomenon of silk skidding after motor reaches certain rotating speed, it is impossible to meet the requirement of the quick wire feed situation of needs.

Fig. 2 is the schematic diagram of the feed device side of the 3D printer feeding stiffening device with double shower nozzles of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following examples are to this hair
Bright explanation and the invention is not limited in following examples.
Embodiment 1：
As illustrated, of the invention pair of shower nozzle 3D printer feeding stiffening device, double shower nozzles are separately positioned on comprising two
Reinforcing mechanisms on two shower nozzles of 3D printer, reinforcing mechanisms include mounting box 1, external motor 2, outside wire feed rolls 3, outside
Bearing 4, V-type support 5, feeding rod 6 and connecting plate, external motor 2 are fixed on the upside of mounting box 1, and outside wire feed rolls 3 is fixed outside
Driven by external motor 2 on portion's motor 2, external bearings 4 are arranged on the side of outside wire feed rolls 3 and external bearings 4 are rotated and set
On the top of a line of V-type support 5, the bottom of V-type support 5 is hinged on the side of mounting box 1, is provided with outside on V-type support 5
Bearing 4 is pressed on the hold-down mechanism on outside wire feed rolls 3, and feeding rod 6 is hollow cylinder, be provided with the another a line of V-type support 5 with
The through hole of the barrel bore of feeding rod 6 matching, the one end of feeding rod 6 is fixed on the lead to the hole site of the another a line of V-type support 5, connecting plate
Two mounting boxs 1 are fixed together.The downside of mounting box 1 is provided with the cavity matched with 3D printer feed device, so may be used
Installed so that original feed device is directly positioned in cavity, so that 3D printer feeding stiffening device of the invention
Using more convenient, it is easy to promote.The rotating speed of external motor 2 is less than the rotating speed of the motor internal of 3D printer feed device, so
Tension force during silk feeding is ensure that by the speed discrepancy of external motor 2 and motor internal, so as to solve the small silk of wire feed mouthful
