s5, feeding and stirring, pressing a feeding button 183, feeding the dyed consumables into a stirring cavity 111, heating by a heating part 41, melting the colored consumables, and stirring by a stirring blade 421;

s6, feeding and extruding, pressing the feeding button 183, and the feeding mechanism 3 pushes the uniformly stirred melted color consumable to move towards the nozzle 11 through the consumable with unmelted rear end and extrude.

During extrusion, corresponding to the two positions in S4, the material is red melting consumable; corresponding to the three positions in S4, the consumable is yellow molten consumable; corresponding to the four positions in S4, the consumable material is blue melting; when the materials correspond to the five positions in the S4, the materials are uniformly stirred and mixed to form an orange melting consumable material; when the material corresponds to the six positions in the S4, the material is mixed after being stirred uniformly to form green melting consumable material; when the materials correspond to the seven positions in the S4, uniformly stirring the materials, and mixing the materials to form purple melting consumables; corresponding to the eight positions in the S4, the black melting consumables are formed by mixing the color after being stirred evenly.

The basic working principle of the invention is as follows: in the using process, the consumable is firstly sent into the channel of the pen main body 1, after the power supply part is electrified, the driving mechanism drives the dyeing part to dye the side wall of the consumable, the wire feeding mechanism 3 drives the dyed consumable to be conveyed to the stirring mechanism 4, when the dyed consumables are inserted into the stirring mechanism 4, the heating part 41 heats the solid color consumables in the stirring mechanism 4 to melt the solid color consumables, and then the stirring mechanism 4 can stir the melted consumables, while the wire feeding mechanism 3 pushes the consumables to move towards the stirring mechanism 4, the front end of the consumables can push the melted color consumables to be extruded out from the nozzle 11, can realize 3D painting, and various colors can be dyed on consumables through the matching of a plurality of groups of dyeing structures 2, therefore, the multifunctional painting device has the effects of rich colors, strong interestingness, flexibility and diversification, and also has the effects of convenience in use, lower cost and better painting effect.

Through adjusting to trade between the dyeing structure 2 that look carousel 182 is steerable different groups and realize trading look process, the user can select different colours by oneself to dye the consumptive material according to own hobby, so, need not to change the consumptive material, can realize polychrome conversion on same root consumptive material, has rich in color, interesting strong effect, uses more in a flexible way, various, and need not to purchase the consumptive material of different colours, and the cost is also lower.

It should be noted that the sequence of the color changing motor 21 and the arrangement of the dyeing members 134 are not limited to the sequence described in this embodiment, and can be adjusted adaptively by changing the program and the number of the dyeing mechanisms, and in other embodiments, two groups of dyeing mechanisms, four groups of dyeing mechanisms, or other numbers of groups of dyeing mechanisms may be adopted, or one driving mechanism may be adopted to drive a plurality of dyeing members to move through a linkage structure. In addition, it should be noted that, during the usage process, the steps related to S1-S3 may also adopt a method of first loading the consumables, then powering on and heating.

The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
