[0001] The invention relates to the technical field of color injection devices, in particular to a marble-like color paste color injection device and a color injection method thereof. Background Art

[0002] Color paste is a semi-finished product made of pigment or pigment and filler dispersed in paint. The one with pure oil as binder is called oily color paste, the one with resin paint as binder is called resin color paste, and the one with water as medium and surfactant added to disperse the color filler paste is called water-based color paste. Color paste is widely used in modern times. In the production process of soap, color paste is often needed to form color paste stripes on the surface of soap.

[0003] Among them, in the soap production process, imitation marble color paste can be used to form imitation marble stripes on the soap surface. When injecting the imitation marble color paste, the imitation marble color paste needs to be injected into the soap extruder.
