Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
embodiment 1:as shown in Figure 1, as shown in Figure 4, the partial enlarged drawing of Fig. 1 as shown in Figure 2, comprises wire leading pipe 1, button 2, sliding bearing 3, motor 4, gear 6, fixed support, wire feed mouth 9 to general assembly drawing to the installation diagram of embodiment 1.
Described fixed support comprises fixed support 5 and lower fixed support 7, and upper fixed support 5 is combined to form wire feed cavity with lower fixed support 7.
Described fixed support is provided with and limits the slideway that slidably reciprocates of described sliding bearing 3, and can promote the button 2 that sliding bearing 3 slides along slideway.Described sliding bearing 3 can be spacingly slidably arranged in wire feed cavity by slideway.Described gear 6 is located in wire feed cavity rotationally, and it is fixedly connected with the driver output axle of motor 4.It is the direction of sliding bearing 3 near gear 6 that the slip of described slideway limits direction.
Specifically in the present embodiment 1, fixed support 7 is descended to be provided with glide path 12 as shown in Figure 3.As depicted in figs. 1 and 2, fixed support 5 is provided with circular hole, sliding way 10, and the driver output axle of described motor 4 inserts the jack being arranged on gear 6 shaft core position through this circular hole, and driven gear 6 start and stop rotate.Described lower fixed support 7 is provided with circular groove towards the inner surface of wire feed cavity, and described gear 6 is rotating to be arranged in circular groove.
Wherein said sliding way 10 is for being arranged on the upper slide opening on upper fixed support 5; Described glide path 12 is for being arranged on the lower slide opening on lower fixed support 7.Described sliding bearing 3 from top to bottom order is made up of upper limit shell of column 11, center shell of column and lower limit shell of column, the diameter of section of described center shell of column is greater than the width of described upper and lower slide opening, and the width of described upper and lower slide opening is greater than the diameter of section of upper limit shell of column 11 and lower limit shell of column.Described sliding bearing 3 can be spacingly slidably arranged in wire feed cavity by sliding way 10 and glide path 12, namely the upper limit shell of column 11 of sliding bearing 3 is through upper slide opening, lower limit shell of column through lower slide opening, can vertically the slip of slide opening limit direction and is arranged on slidably reciprocating in wire feed cavity.The cross section of described upper slide opening and lower slide opening is elongated strip shaped or oval or Pear-Shaped.
On described fixed support, side is provided with wire feed mouth 9, and opposite side is connected with wire leading pipe 1, and wire feed mouth 9 is communicated with the centre position of sliding bearing 3 and gear 6 and wire leading pipe 1 forms wire feed passage.Described wire feed mouth 9 is horn-like wire feed mouth.
embodiment 2:substantially identical with embodiment 1 structure, something in common is not repeated, and difference is:
Specifically in the present embodiment 2, described sliding way 10 is for being arranged on upper fixed support 5 towards the upper hopper chute on the inner surface of wire feed cavity; Described glide path 12 is for being arranged on lower fixed support 7 towards the gliding groove on the inner surface of wire feed cavity.
Described sliding bearing 3 upper end is positioned at upper hopper chute, lower end is positioned at gliding groove, can along upper and lower chute slip limit direction be arranged on slidably reciprocating in wire feed cavity.
The bottom land of described upper hopper chute and gliding groove is elongated strip shaped or oval or Pear-Shaped.
For embodiment 1, the course of work of this wire feeder is: consumptive material dish 13 is equipped with 3D and prints tubulose used or thread consumptive material 8, and after motor 4 is energized, driven gear 6 rotates by its output shaft; Sent into by consumptive material 8 in the horn-like wire feed mouth 9 on fixed support, the consumptive material being positioned at wire feed mouth A point enters into the centre position of sliding bearing 3 and gear 6 along wire feed mouth.
Now push button 2, button 2 promotes the slideway that sliding bearing 3 formed along sliding way 10 and glide path 12 and slides to gear 6, and then sliding bearing 3 pushes consumptive material 8 and makes consumptive material 8 and gear 6 interfere, the gear 6 of rotation is just bitten consumptive material 8 and is delivered in the wire leading pipe 1 of wire feed passage.Under the continuous rotation of gear 6, consumptive material 8 will deliver to point of destination (as the B point) place of wire leading pipe automatically along wire feed passage, as used in 3D printing head for downstream unit.
In the present embodiment, the gear 6 of 2 rotations that push button bites consumptive material 8 when constantly being delivered in the wire leading pipe 1 of wire feed passage, and the consumptive material 8 of pushed forward can give sliding bearing 3 one external force conversely; Even when sliding bearing 3 not only can spacing slip in wire feed cavity, when also can rotate in slideway under external force, consumptive material 8 can reversely rotate by automatic traction sliding bearing 3 to conversely the external force of sliding bearing 3 with gear 6.Traction consumptive material is continued by by downstream unit such as the 3D printing head being positioned at point of destination after consumptive material is sent to point of destination (as B point), now can Panasonic's button 2, under the pulling force effect of inertia or upstream and downstream silk device, sliding bearing 3 can be pushed open along slideway or be flicked to conversely the external force of sliding bearing 3 and realizes resetting, now by the automatic feeding end-of-job of this wire feeder by consumptive material 8 along the conveying of wire feed passage automatically laterally.Follow-up will by upstream device as 3D printing head continue traction consumptive material, when needs change again or supplementary consumptive material time enable this wire feeder again.In general, this device can realize the automation wire feed to printer head, simplifies wire feed operation, improves wire feed efficiency.
Above implementation column does not form restriction to the present invention, and relevant staff is in the scope not departing from the technology of the present invention thought, and the various change carried out and amendment, all drop in protection scope of the present invention.
