The operation principle of the plastic product dyeing device 10 is as follows: dye storage assembly 100 is used to provide dye liquor to dye brush 300. The dye liquor to be used stored in the dye silo 110 is delivered to the brush rod 310 of the dyeing brush 300 through the delivery hose 120. When a user needs to use the plastic product dyeing apparatus 10 to perform painting and dyeing work, the material delivery valve 121 disposed on the material delivery hose 120 is opened, so that the dye solution to be used stored in the dyeing bin 110 can smoothly enter the extrusion cavity 301 formed in the brush rod 310 through the material delivery hose 120. During the smearing and dyeing work of the user using the plastic product dyeing device 10, the dye supply assembly 200 utilizes the screw principle to extrude the dye liquor to be used in the extrusion cavity 301 from the brush head 320. Specifically, the rotating motor 210 drives the pushing rod 230 to move downwards in the squeezing cavity 301 along the rotating rod 220 by driving the rotating rod 220 to rotate, the squeezing plate 231 arranged below the pushing rod 230 pushes the dye in the squeezing cavity 301 to the mass containing cavity 303 formed in the brush head 320, and the dye solution in the mass containing cavity 303 is discharged through the discharge holes 304 formed in the brush head 320 under the pressure effect. The dye liquor discharged from each discharge hole 304 wets the bristles 321 provided on the brush head 320, thereby continuously supplying the dye liquor to the bristles 321. Meanwhile, the discharge holes 304 are uniformly opened between the bristles 321, so that the bristles 321 are uniformly wetted, and the working stability of the dyeing brush 300 is further improved.

In one embodiment, the bristles 321 are stiff bristles. The hard brush hair is not easy to bend and deform, has long service life and is suitable for products to be dyed with hard texture. In another embodiment, the bristles are soft bristles which are soft, light and good in dye absorption and are suitable for products to be dyed with soft texture.

In order to increase the operation stability of the dye storage device 100, in the present embodiment, the feeding valve 121 is an electrically operated valve. The electric valve has simple structure and easy maintenance, and can be used for controlling the flow of various types of fluid such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The action moment of the electric valve is larger than that of the common valve, and the opening and closing action speed of the electric valve can be adjusted.
