Background technology
Existing 3D printer is divided into a single spraying printer and many nozzle printings machine (shower nozzle number≤3), comprise charging motor, shower nozzle and return idler, in the time of needs transfer material, motor clockwise rotates, and drives return idler to rotate counterclockwise, thereby material is proceeded to downwards and enters shower nozzle, when the material that needs a person with the qualifications of a general exits, motor rotates counterclockwise, and drives return idler to clockwise rotate, and material is upwards produced; If when need to use multiple material to print, two single spraying head units of use are carried out side by side, one of them shower nozzle energising work, another one shower nozzle no power is not worked, if when need to print another material, "on" position is switched, another one shower nozzle work, and shower nozzle before is not worked; If demand is printed bi-material, need two single spraying head units, printing different materials needs several single spraying head units, so this must increase the cost of 3D printer; Owing to only having at most on the market the 3D printer of 3 shower nozzles, if demand is printed more materials, need manually to go more conversion materials, increased greatly the complexity of operation, and personnel's specialty has been had relatively high expectations.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of 3D printer single spraying head multiple material switching device shifter that once can print multiple material.
Technical solution of the present invention is achieved in that a kind of 3D printer single spraying head multiple material switching device shifter, comprises fixed mount, main motor and shower nozzle installing rack; The upper surface circular array of described fixed mount is shown a plurality of feeding mechanisms; Each feeding mechanism comprises respectively charging motor, active roller and return idler; Described active roller is connected with the rotating shaft of charging motor; Described charging Electric Machine Control active roller rotates, thereby drives return idler, to realize, is arranged on the feeding of the material between active roller, return idler or retreats; Described main motor is connected by connecting rod with shower nozzle installing rack; The rotating shaft of described main motor drives connecting rod to rotate to adjust the position of shower nozzle installing rack below fixed mount; Under the active roller of described each feeding mechanism, return idler intermediate gap, be equipped with the through hole for charging; During use, main machine shaft drives the shower nozzle installing rack that shower nozzle is installed to rotate to feeding mechanism below by connecting rod, and material is sent into and in shower nozzle, added hot-working by through hole.
Preferably, in the middle of described fixed mount, be provided with circular insulating collar.
Preferably, described feeding mechanism is at least 2.
Preferably, described feeding mechanism is at least 4.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of 3D printer single spraying head multiple material switching device shifter of the present invention, adopt the rotating shaft of main motor to drive connecting rod to rotate to adjust the position of shower nozzle installing rack below fixed mount, while carrying out the charging of different materials, the position of main Electric Machine Control shower nozzle installing rack makes shower nozzle rotate to feeding mechanism below, with the through-hole alignment charging on fixed mount, realize a single spraying multiple material handoff functionality, can greatly reduce the cost of 3D printer, and the complexity that reduces the personnel to operate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of multiple material switching device shifter for a kind of 3D printer single spraying head of the present invention;
Wherein: 1, fixed mount; 2, main motor; 3, shower nozzle installing rack; 4, feeding mechanism; 5, charging motor; 61, active roller; 62, return idler; 7, connecting rod; 8, through hole; 9, circular insulating collar; A, b, c, d are material.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Be a kind of 3D printer single spraying head multiple material switching device shifter of the present invention as shown in Figure 1, comprise fixed mount 1, main motor 2 and shower nozzle 3; The upper surface circular array of described fixed mount 1 is shown four feeding mechanisms 4; Each feeding mechanism 4 comprises respectively charging motor 5, active roller 61 and return idler 62; Described charging motor 5 is controlled active roller 61 and is rotated, thereby drives return idler 62, to realize, is arranged on the feeding of the material between active roller 61 and return idler 62 or retreats; Described main motor 2 is connected by connecting rod 7 with shower nozzle installing rack 3; The rotating shaft of described main motor 2 drives connecting rod 7 to rotate and adjusts the position of shower nozzle installing rack 3 below fixed mount 1; Under the active roller 61 of described each feeding mechanism 4, return idler 62 intermediate gap, be equipped with the through hole 8 for charging; During use, the rotating shaft of main motor 2 drives the shower nozzle installing rack 3 that shower nozzle is installed to rotate to feeding mechanism 4 belows by connecting rod 7, in the time of needs transfer material, charging motor 5 clockwise rotates, active roller 61 drives return idler 62 to rotate counterclockwise, thereby material is proceeded to downwards and enters through hole to the shower nozzle being arranged in shower nozzle installing rack 3; When the material that needs a person with the qualifications of a general exits, charging motor 5 rotates counterclockwise, and active roller 61 drives return idler 62 to clockwise rotate, and material is upwards produced; Feeding mechanism 4 imports material after shower nozzle, and shower nozzle heats, and material sprays by shower nozzle, and connecting rod 7 guarantees that shower nozzle can be rotated along with the rotation of main motor 2; When shower nozzle needs more conversion materials, material exits after shower nozzle, and main motor 2 will be worked, by shower nozzle installing rack 3 certain angle of rotation; In the middle of fixed mount, be provided with circular insulating collar 9, the heat that the charging motor 5 in each feeding mechanism 4 is produced does not flow mutually, reduces the impact of heat on material
