Description

Technical field:

[0001] The utility model belongs to the technical field of plastic color matching machines, in particular to a plastic color matching machine. Background technology:

[0002] Plastic coloring is generally achieved by adding color powder and plastic particles during production to meet color requirements. Plastic particles can be colored according to the color specified by the customer. With the help of a plastic color matching machine, a certain proportion of color powder and plastic particles are placed in a mixing chamber for mixing and stirring to obtain plastic particles of the specified color.

[0003] However, since the toner is a powdery substance, it will float in the air after being sprayed into the mixing chamber and is not easy to adhere to the plastic particles. At the same time, some plastic particles are not easy to be adhered to by the toner due to their own characteristics. Even with the help of the stirring component in the mixing chamber for stirring and mixing, the toner cannot be effectively and evenly adhered to the plastic particles. Summary of the invention:

[0004] The utility model aims to provide a plastic color matching machine, which adds a dosing nozzle in the mixing chamber of the existing color matching machine body, sprays color powder diffusion oil into the mixing chamber by means of the dosing nozzle, so that the color powder can be closely attached to the plastic particles under the action of the color powder diffusion oil.

[0005] The utility model is achieved in this way:

[0006] A plastic color matching machine comprises a color matching machine body, a mixing chamber, and a plastic particle feeding channel and a color powder feeding channel connected to the mixing chamber are arranged in the color matching machine body, an assembly through hole is arranged on the inner wall surface of the mixing chamber, a dosing nozzle is arranged on the assembly through hole, an injection end of the dosing nozzle is connected to the mixing chamber, and a liquid inlet end is connected to external color powder diffusion oil through a pipe fitting.

[0007] In the above-mentioned plastic color matching machine, the toner diffusion oil is silicone oil, salad oil or machine oil.

[0008] In the above-mentioned plastic color matching machine, the mixing nozzle is located above the port in the color powder feeding channel.

[0009] In the above-mentioned plastic color matching machine, the external color powder diffusion oil is connected to the oil inlet of the oil pump, the oil outlet of the oil pump is connected to the liquid inlet end of the dosing nozzle through a pipe fitting, and an electromagnetic throttle valve is provided on the pipe fitting between the oil pump and the dosing nozzle, and the control assembly controls the opening or closing of the electromagnetic throttle valve and the oil pump.

[0010] In the above-mentioned plastic color matching machine, a stirring blade for stirring plastic particles, color powder and color powder diffusion oil is rotatably connected in the mixing chamber through a rotating shaft, and one end of the rotating shaft is drivingly connected to a driving motor fixed on the color matching machine body.

[0011] In the above-mentioned plastic color matching machine, a toner conveying component for quantitatively conveying toner is arranged in the toner feeding channel.

[0012] The outstanding advantages of the utility model compared with the prior art are:

[0013] The utility model has a simple structure and a reasonable design. A dosing nozzle is directly added to the mixing chamber of the existing color matching machine body. The dosing nozzle is used to spray color powder diffusion oil into the mixing chamber, so that the color powder can be closely attached to the plastic particles under the action of the color powder diffusion oil, thereby reducing the phenomenon of color powder flying around in the mixing chamber, and diluting the color powder to make the color powder more uniform when mixing with the plastic particles.
