DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 4 , a feeding device for pigment production, comprising a stirring box 1, a stirring mechanism 2, and a feeding mechanism 3;

[0027] The stirring mechanism 2 is installed in the stirring box 1 and is used to stir the solid pigment raw material; specifically, the original granular initial material is ground to form the pigment raw material, and a variety of different pigment raw materials enter the stirring box 1 to be mixed to form a new, formed pigment;

[0028] The feeding mechanism 3 is installed on the top of the mixing box 1, and includes a feeding shell 301 and a feeding port 303;

[0029] An inlet baffle 302 is arranged between the feed port 303 and the feeding shell 301. The inlet baffle 302 is movable to isolate or open the feed port 303 from the space inside the feeding shell 301. The feeding chamber in the feeding shell 301 is connected to the stirring box 1. A cleaning motor is installed in the feeding shell 301. One end of the output shaft of the cleaning motor is connected to the cleaning shaft 304. A cleaning blade 305 is fixedly installed on the cleaning shaft 304. The cleaning blade 305 is arranged in a spiral shape. There is a certain interval between the spiral cleaning blade 305 and the inner wall of the feeding shell 301, and the direction of rotation of the cleaning motor output shaft is the same as the direction of spiral deflection of the cleaning blade 305. The cleaning blade 305 rotates together with the cleaning shaft 304. During the rotation, the pigment on the inner wall of the feeding shell 301 is pushed to rotate. The cleaning blades 305 are spirally distributed, which can push the pigment to fall along the curved surface of its outer wall. The falling trajectory is stable, and the connections at various places are relatively smooth, and it is not easy to get stuck.

[0030] More specifically, a fixing seat is rotatably mounted on the cleaning shaft 304, and a cleaning pipe 306 is inserted in the fixing seat. The cleaning pipe 306, the internal cavity of the fixing seat, the internal cavity of the cleaning shaft 304, and the internal cavity of the cleaning blade 305 together form a first gas channel. The first gas channel is provided with a first exhaust port on the side wall of the cleaning blade 305 close to the feeding shell 301, and the first exhaust port is aligned with the inner wall of the feeding shell 301. When the first gas channel is ventilated, the gas can be blown to the inner wall of the feeding shell 301 to blow away the pigment adhered to the inner wall of the feeding shell 301. During the rotation of the cleaning blade 305, the airflow blown out of the first exhaust port therein rotates accordingly, and the cleaning blade 305 is spirally distributed, and the pigment particles adhered to the feeding shell 301 will fall in an arc shape to the lower side, and the falling trajectory is stable, and there is no need for the cleaning blade 305 and the inner wall of the feeding shell 301 to rub against each other, so as to avoid mutual wear between the two.

[0031] In a further embodiment, one end of the cleaning pipe 306 away from the fixing seat is inserted into the transfer member 307, and the transfer member 307 is connected to the air intake pipe. A channel connector 308 is rotatably installed in the transfer member 307, and the channel connector 308 is used to connect the air intake pipe to any one of the first gas channel and the second gas channel. The channel connector 308 includes two side plates, and the two side plates are in contact with the inner wall of the transfer member 307. The second gas channel includes a pressurized pipe 313, and one end of the pressurized pipe 313 away from the transfer member 307 is inserted into the feeding shell 301; the two side plates in the channel connector 308 can surround a cavity, and the cavity is always connected to the air intake pipe. With the rotation of the channel connector 308, the cavity can be connected to the first gas channel or the second gas channel. The second gas channel is connected to the feeding shell 301, which is used to provide a downward blowing force during the pigment feeding process to accelerate the pigment feeding speed;

[0032] Specifically, the channel connector 308 is connected to a driving motor 309 for driving the same to rotate. The driving motor 309 is a bidirectional motor. A gear 310 is installed on the other output shaft of the bidirectional motor. The gear 310 is connected to a rack 311 through tooth meshing transmission. The rack 311 is slidably connected to a guide frame 312. The guide frame 312 is fixedly installed on the outer wall of the feeding shell 301.

[0033] The feeding mechanism 3 is divided into two types during the feeding process. In the first type, the pigment enters the feeding shell 301 through the feeding port 303. At this time, it is a feeding state. At this time, the inlet baffle 302 needs to be removed from the feeding port 303. At the same time, the channel connector 308 connects the air intake pipe with the second gas channel, and the gas enters the feeding shell 301 to accelerate the falling of the pigment. In this process, some pigments will adhere to the inner wall of the feeding shell 301. After a specified amount of pigment enters, the inlet baffle 302 needs to block the feeding port 303. Figure 2 As shown, this is the cleaning state, which is mainly used to clean the pigment particles adhering to the inner wall of the feeding shell 301 to ensure that the amount of pigment entering the mixing box 1 maintains a specified weight.
