The 3D printer provided for clearer explanation this utility model, makees concrete below in conjunction with embodiment Explanation.Fig. 1 is the appearance assumption diagram of the 3D printer of an embodiment.Fig. 2 is embodiment illustrated in fig. 1 The cut-away view of 3D printer.Fig. 3 is the rotating mechanism of 3D printer of embodiment illustrated in fig. 1, shifting The attachment structure figure of motivation structure and fixed mechanism.Fig. 4 is that the 3D printer of embodiment illustrated in fig. 3 is along mobile electricity Machine is to the profile of connecting line direction cutting between slide block.Fig. 5 is the 3D printer folding of embodiment illustrated in fig. 1 The appearance assumption diagram of poststack.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, in one embodiment, 3D printer include printing head, First prints arm 1000, second prints arm 2000, print platform 3000, print platform support 4000, rotation Rotation mechanism 5000, travel mechanism 6000 and fixed mechanism 7000.

Print platform 3000 is located at print platform support 4000 top.Printing head is located at the first printing arm 1000 In, for jet printing material.It is vertical that first printing arm 1000 prints arm 2000 with second.Second prints Arm 2000 top prints arm 1000 with first and is connected, and second prints arm 2000 bottom and rotating mechanism 5000 Connect.Travel mechanism 6000 is connected with print platform support 4000, rotating mechanism 5000 respectively.

Wherein, rotating mechanism 5000, revolves along print platform support 4000 for controlling the second printing arm 2000 Turn, and rotating mechanism 5000 at least controls the first printing arm 1000, second print arm 2000 distinguish the most parallel, It is perpendicular to print platform 3000.Wherein, first print arm 1000, second print arm 2000 the most parallel, After being perpendicular to print platform 3000, rotating mechanism 5000 should be out of service, and only needs by travel mechanism 6000 The position of the position or printing head that adjust printing head has met then without adjusting when requiring, 3D printer is i.e. Can start to print.

Travel mechanism 6000, controls rotating mechanism 5000 and second and prints arm 2000 along print platform support 4000 Move horizontally.Therefore under the mating reaction of rotating mechanism 5000 and travel mechanism 6000, it is possible to make this 3D printer is erecting printing and is packing up switching between folded state.

In the present embodiment, under erecting print state, as it is shown in figure 1, first prints arm 1000, second Arm 2000 is the most parallel, be perpendicular to print platform 3000 in printing, and printing head is just to print platform 3000, At this moment 3D printer can start normal print.

Under packing up folded state, as it is shown in figure 5, the second printing arm 2000 and the first printing arm 1000 are equal Residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane, and first Print arm 1000 the shortest with the distance of print platform support 4000, it should be noted that first prints arm 1000 With print platform support 4000 apart from the most in short-term, the volume of 3D printer is in the state of minimum, at this moment 3D Printer is in packs up folded state.If such as print platform support 4000 printing arm 2000 with second connect When tactile side is the most vertical with other adjacent two sides, then when the second printing arm 2000 is close to above-mentioned During a side in other adjacent two sides, i.e. second prints arm 2000 and print platform support 4000 Beeline be zero, and at this moment the volume of 3D printer is minimum.

When rotating mechanism 5000 control the first printing arm 1000, second print arm 2000 rotate to the most parallel, After being perpendicular to the state of print platform 3000, in order to overcome the structure that can rotate in rotating mechanism 5000 to exist It is possible to there is situation about rotating by mistake after rotating mechanism 5000 is out of service, the present embodiment passes through fixed mechanism 7000 overcome this defect, and specific implementation is as follows.

Fixed mechanism 7000, is installed on print platform support 4000.When first prints arm 1000, second Printing arm 2000 switches to parallel, to be perpendicular to print platform 3000 state respectively and rotating mechanism 5000 stops After only running, fixed mechanism 7000 suppresses the structure that can rotate in rotating mechanism 5000 because of other outer masterpieces With rotating.

Therefore, fixed structure 7000 can remain whirler after rotating mechanism 5000 is out of service The structure that can rotate in structure 5000 is in fixing non-rotary state, to avoid misrouting dynamic situation. And this rotating mechanism 5000 remains to the movement along with travel mechanism 6000 and moves afterwards, so that printing spray Head can move to position injections different on print platform 3000 and beat under the control of travel mechanism 6000 Printed material material, it is ensured that being normally carried out of print procedure.

Concrete, as shown in Figure 2, Figure 3, Figure 4, fixed structure 7000 includes bearing pin 7100.Bearing pin 7100 One end be fixed on print platform support 4000, the other end is unsettled and can in pointing rotation mechanism 5000 The structure rotated, bearing pin 7100 is in parastate with the moving direction of rotating mechanism 5000 simultaneously.

Corresponding, in order to realize the above-mentioned functions of fixed mechanism 7000, rotating mechanism 5000 can rotate Structure be provided with for the pin-and-hole 5110 through bearing pin 7100, and the position of pin-and-hole 5110, meet when rotating Mechanism 5000 is out of service and the first printing arm 1000, second prints arm 2000 and switches to parallel, vertical respectively Straight when the state of print platform, pin-and-hole 5110 and bearing pin 7100 keep coaxial condition.

Therefore, as long as pin-and-hole 5110 keeps coaxial with bearing pin 7100, just can rotating mechanism 5000 move to Behind the position of bearing pin 7100 so that bearing pin 7100 inserts in pin-and-hole 5110, keep rotating mechanism 5000 In the structure that can rotate keep existing angle constant in a rotational direction, and then reach to suppress rotating mechanism The effect by mistake rotated is there is in the structure that can rotate in 5000 after rotating mechanism 5000 is out of service.

It is understood that fixed mechanism 7000 is not limited to by above-mentioned a kind of situation, as long as can suppress to rotate The structure that can rotate in mechanism 5000 rotates because of other External Force Actings.Such as by flat in printing Fix one group on platform support 4000 and there is certain length and the snap component that can move, and at rotating mechanism The most coaxial assembly is set outside the structure that can rotate in 5000.As long as rotating mechanism 5000 moves afterwards To above-mentioned snap component, can suppress rotating mechanism 5000 can rotate by the fixed form of buckle Structure occurs to rotate after rotating mechanism 5000 is out of service by mistake.

It addition, when initial design is installed just according to above-mentioned when rotating mechanism 5000 is out of service and first print When arm the 1000, second printing arm 2000 switches to parallel, to be perpendicular to print platform state respectively, pin-and-hole 5110 keep coaxial condition with bearing pin 7100, bearing pin 7100 and pin-and-hole 5110 are respectively arranged at printing flat In platform support 4000, rotating mechanism 5000 can the relevant position of rotational structure.Afterwards at 3D printer In running, bearing pin 7100 is fixing all the time, and it is out of service to have only to control rotating mechanism 5000 Moment.So as long as rotating mechanism 5000 is out of service, bearing pin 7100 is in pin-and-hole 5110 Coaxial state, then show at this moment first print arm 1000, second print arm 2000 switch to respectively parallel, It is perpendicular to the state of print platform.Therefore, to be also used as rotating mechanism 5000 out of service for bearing pin 7100 Basis reference.

Concrete, fixed mechanism 7000 also includes interconnective inductive switch and controller, and controller is also It is connected with rotating mechanism 5000.This inductive switch and controller i.e. can be used to realize above-mentioned control rotating mechanism The function in 5000 moment out of service.

Wherein, inductive switch, the anglec of rotation of the structure that can rotate in monitoring rotating mechanism 5000, and This anglec of rotation corresponding first print arm 1000, second print arm 2000 switch to respectively parallel, be perpendicular to beat When printing the state of platform 3000, export Continuity signal.Inductive switch can be arranged in rotating mechanism 5000 Near the structure that can rotate, but the most concrete position limitation, as long as being capable of above-mentioned functions. Specifically, inductive switch can select touching switch or fiber switch or other kinds of switch.

Controller, receives the signal that inductive switch transmits, and controls to rotate after receiving above-mentioned Continuity signal Mechanism 5000 is out of service.Therefore, when controller control rotating mechanism 5000 is out of service, first dozen Print arm 1000, second prints arm 2000 and has been in parallel, to be perpendicular to print platform 3000 state, afterwards After rotating mechanism 5000 is out of service, when rotating mechanism 5000 moves to the position of close bearing pin 7100, The structure that can rotate in rotating mechanism 5000 can be fixed by bearing pin 7100.

It is understood that be used for realizing the structure of control rotating mechanism 5000 moment function out of service not It is limited to above-mentioned a kind of situation, such as, can be not provided with controller, and directly be realized above-mentioned by rotating mechanism 5000 The function of controller.

Concrete, rotating mechanism 5000 includes support unit 5100, rotary unit 5200 and electric rotating machine 5300, And support unit 5100, rotary unit 5200 and electric rotating machine 5300 are sequentially connected with.
