  • the color changing dial 182 rotates to the eighth position, the three color changing motors 21 rotate at the same time, the first color changing motor 211 drives the first slider 221 to move, thereby pushing the first dyeing piece 1341 to dye the consumables red, and the second changing The color motor 212 drives the second slider 222 to move so as to push the second dyeing element 1342 to dye the consumables yellow, and the three-color changing motor 21 drives the third slider 223 to move to push the third dyeing element 1343 to dye the consumables blue, such as Figure 17 shows the corresponding state;
  • the basic working principle of the present invention is as follows: during use, the consumables are first fed into the channel of the pen main body 1, after the power supply component is energized, the driving mechanism drives the dyeing piece to dye the sidewall of the consumables, and the silk feeding mechanism 3 drives the dyed
  • the consumables are transported to the stirring mechanism 4, and when the dyed consumables extend into the stirring mechanism 4, the heating component heats the solid colored consumables in the stirring mechanism 4 to melt them, and then the stirring mechanism 4 can melt the molten material.
  • the consumables are stirred.
  • the wire feeding mechanism 3 pushes the consumables to move to the stirring mechanism 4, the front end of the consumables will also push the molten colored consumables out of the nozzle 11, so that 3D drawing can be realized.
  • the consumables are dyed with various colors, so that it has the effects of rich colors, strong interest, flexibility and diversification, and also has the functions of convenient use, low cost and better drawing effect.
  • the color changing process between different groups of dyeing structures 2 can be controlled. Users can choose different colors to dye the consumables according to their own preferences.
  • the multi-color conversion is realized on the consumables, which has the effect of rich colors and strong interest, and the use is more flexible and diverse, and there is no need to purchase consumables of different colors, and the cost is also lower.
  • the order of the color changing motors 21 and the arrangement of the dyeing parts 134 are not limited to the order described in this embodiment, and can be adjusted adaptively by changing the program and the number of dyeing mechanisms.
  • two groups of dyeing mechanisms, four groups of dyeing mechanisms, or other multiple groups of dyeing mechanisms may be used, and a driving mechanism may also be used to drive a plurality of dyeing pieces to move through a linkage structure.
  • the related steps of S1-S3 can also adopt the method of loading consumables first, then powering on and heating.

Abstract

La présente invention concerne un stylo d'impression 3D ayant des structures de coloration et son procédé de changement de couleur. Le stylo d'impression comprend : un corps principal de stylo (1), lequel corps principal de stylo (1) est pourvu d'une pluralité de groupes de structures de coloration (2), chaque structure de coloration (2) comprenant un mécanisme d'entraînement et un élément de coloration (134), le mécanisme d'entraînement poussant l'élément de coloration (134) à colorer un produit consommable (8), le produit consommable (8) étant coloré lorsque l'élément de coloration (134) est étroitement comprimé contre le produit consommable (8), et l'élément de coloration (134) étant déplacé à l'opposé du produit consommable (8) après que le produit consommable (8) soit coloré ; et un élément de contrôle du changement de couleur, qui est conçu pour coopérer avec la pluralité des groupes de structures de coloration (2) d'une manière contrôlée, et étant utilisé pour contrôler la commutation des différentes structures de coloration (2). À l'aide d'une nouvelle structure mécanique, l'élément de contrôle du changement de couleur peut être ajusté pour commander aux différents groupes de structures de coloration (2) de réaliser le processus de changement de couleur, de sorte qu'un utilisateur peut sélectionner différentes couleurs tout seul pour colorer des produits consommables, et, ainsi, un changement multicolore peut être atteint sur le même produit consommable sans nécessité de remplacer le produit consommable, les effets d'être riche en couleur et d'avoir un niveau élevé d'intérêt sont atteints, et des produits consommables ayant différentes couleurs n'ont pas besoin d'être achetés, de sorte que le coût est relativement bas.
