Three consumptive material perforation 411 has radially been seted up to carousel 41, can insert the consumptive material that has three kinds of different colours to set for through carousel 41 clockwise and anticlockwise reciprocating type revolution mechanic, prevent to rotate towards a direction and appear the phenomenon that multiple consumptive material knotted.
When the invention is used, when the distance between the lower end of the spray head 21 and the object carrying plate 11 is adjusted, the spray head 21 moves to the next corner through the arranged laser sensor 5 after the lower end of the spray head 21 reaches the set distance, if the next corner is larger than or smaller than the set value, the spray head 21 stops moving at the moment, then the adjustment is carried out through adjusting an adjusting piece (the prior known technology and the repeated description are omitted) at the bottom of the object carrying plate 11, after the four corners are adjusted in sequence, three consumables with different colors are respectively inserted into corresponding consumable through holes 411, and the lowest end does not exceed the bottom of the rotary plate 41, then the first consumable is arranged right above the consumable penetrating pipe 22, then the second air cylinder 432 works and drives the driving motor 431 and the rubber rotary plate 43 to move towards the direction of the arc-shaped groove 412, and the outer wall of the rubber rotary plate 43 is abutted against the consumables at the side of the through groove 413, the rubber turntable 43 is then rotated clockwise, the consumables are inserted into the consumable penetration tube 22 by wave motion under the action of rotation and squeezing force, the consumables are then slowly fed by a transmission mechanism (known in the art) inside the nozzle assembly 2, and then the second cylinder 432 is contracted to withdraw the drive motor 431 and the rubber turntable 43.
When the color of the consumable material needs to be changed in the printing process, the second stepping motor 42 drives the turntable 41 to rotate, the turntable 41 and the consumable material penetrating pipe 22 form a scissors structure to cut off the consumable material, then the next consumable material is rotated to the position above the consumable material penetrating pipe 22, meanwhile, the first air cylinder 323 drives the first stepping motor 321 and the material collecting hopper 32 to move downwards, the position above the material collecting hopper 32 is arranged below the spray head 21, then the first stepping motor 321 drives the material collecting hopper 32 to rotate one hundred eighty degrees and is arranged under the spray head 21, the actions are repeated to enable the rubber turntable 43 to approach the through groove 413, the consumable material on the side is shifted to the interior of the consumable material penetrating pipe 22, the high-frequency induction heating coil 31 is electrified to locally heat the spray head 21 in the penetrating process, and the residual material adhered to the bottom of the spray head 21 is heated to form liquid and fall to the material collecting hopper 32, and (4) recovering the residual materials until new colors are extruded, rotating the aggregate bin 32 by one hundred eighty degrees at the moment after the residual materials are processed, moving the aggregate bin up and down along the plumb line direction, and lifting the aggregate bin 32 upwards to avoid interference between the lower part of the aggregate bin 32 and a mold during modeling.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
