The dyeing apparatus 10 having the raw material stirring function described above operates as follows: dye storage assembly 100 is used to provide dye liquor to dye brush 300. A dye silo 110 in the dye storage assembly 100 is used to store the dye liquor to be used. According to different products to be dyed, a user adds various dye raw materials into the dye bin 110 through a feeding valve 111 arranged at the top of the dye bin 110. In one embodiment, the charging valve 111 is an electrically operated valve, which has a simple structure and is easy to maintain, and can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, slurry, oil, liquid metal, radioactive media, and the like. The electrically operated valve has a greater moment of action than a conventional valve, which improves the safety of the dye storage assembly 100. After the dye materials are added, the stirring motor 410 in the stirring assembly 400 drives the stirring blades 440 to rotate through the stirring shaft 420 and the blade connecting piece 430 to stir the various dye materials to form a dye solution. 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 dyeing apparatus 10 with the raw material stirring function to perform painting and dyeing work, the material delivery valve 121 arranged 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. In the process of smearing and dyeing work performed by a user by using the dyeing device 10 with the raw material stirring function, the dye supply assembly 200 utilizes the screw rod 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 the discharge holes 304 wets the bristles 321 arranged on the brush head 320, and the dye liquor is continuously provided for the dyeing equipment with the raw material stirring function. The plurality of discharge holes 304 are uniformly opened between the bristles 321, so that the bristles 321 are uniformly wetted, further improving the operational stability of the brush 300. In the present 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.

It will be appreciated that the rigid rubber plate is in resilient compression during operation in the brush bar 310, with the periphery of the rigid rubber plate abutting the inside wall of the brush bar 310. On the other hand, the hard rubber plate with good wear resistance ensures the structural integrity of the extrusion plate 231 in the long-term operation process of the brush rod 310, thereby ensuring that the extrusion plate 231 and the inner side wall of the brush rod 310 have good tightness for a long time. The hard rubber plate is softer and tougher than the metal plate and the plastic plate, so that the extrusion plate 231 can not scratch the inner side wall of the brush rod 310 when running in the brush rod 310, and good sealing performance between the extrusion plate 231 and the inner side wall of the brush rod 310 is ensured for a long time. In another embodiment, the soft rubber layer is arranged on the surface of the outer layer of the extrusion plate, so that the extrusion plate is ensured to have certain elasticity, the wear resistance of the surface of the extrusion plate is improved, and the tightness between the extrusion plate and the inner side wall of the filter cylinder is improved. Thus, the sealing performance between the extrusion plate 231 and the inner sidewall of the brush rod 310 is improved when the extrusion plate 231 operates in the brush rod 310, and the operation stability of the dye supply assembly 200 is improved.

In order to avoid that the dye liquor in the dyeing bin 110 stays at the bottom of the dyeing bin 110 for a long time, which causes the dye liquor to go moldy and go bad, please refer to fig. 1, in one embodiment, the input end of the material conveying hose 120 is communicated with the bottom of the dyeing bin 110, and the bottom of the dyeing bin 110 is arranged in an inverted cone shape.
