The mixing mechanism 2 includes a mixing tank 201, a motor 203 is arranged on the top of the mixing tank 201, the output end of the motor 203 is connected to a stirring shaft 204, main stirring rods 205 are symmetrically installed on the outer wall of the stirring shaft 204, a rotating shaft 206 is movably installed at the bottom of the main stirring rod 205, and a plurality of auxiliary stirring rods 207 are evenly distributed on the outer wall of the rotating shaft 206. One end of two of the auxiliary stirring rods 207 is fixedly connected to a resistance plate 208, and a discharge port 210 is arranged at the bottom of the mixing tank 201; The quantitative addition mechanism 3 includes a conveying pipeline 301. The bottom of the discharge port 210 is connected to the top of the conveying pipeline 301. One end of the conveying pipeline 301 is movably sleeved with a sealing cover 302. A feeding motor 303 is installed on the side of the sealing cover 302. The output end of the feeding motor 303 is connected to a transmission shaft 304. A screw conveyor 305 is arranged on the outer wall of the transmission shaft 304. One end of the bottom of the conveying pipeline 301 is provided with a quantitative discharge pipe 307. The bottom of the sealing cover 302 is fixedly connected with a connecting piece 308. One end of the connecting piece 308 is fixedly connected with a moving block 309. A lead screw 310 is threadedly connected inside the moving block 309. One end of the lead screw 310 is provided with an adjusting motor 311. Both sides of the adjusting motor 311 are fixedly connected with mounting rods 312. One end of the transmission shaft 304 is provided with a positioning seat 306. The positioning seat 306 is installed at the other end of the conveying pipeline 301.

[0023] A top cover 202 is arranged on the top of the mixing tank 201. A motor 203 is installed on the top of the top cover 202. A stirring shaft 204 passes through the inside of the top cover 202. Oblique stirring rods 209 are symmetrically installed at the bottom end of the stirring shaft 204. The bottom of the rotating shaft 206 is movably connected to the middle of the oblique stirring rod 209.

[0024] In this embodiment, different additives to be used are stored in the storage box 101. When the valve at the discharge port 106 is opened, the additives can be added into the mixing tank 201 in proportion. After the additives are added into the mixing tank 201, the motor 203 drives the stirring shaft 204 to rotate, thereby driving the main stirring rod 205 and the oblique stirring rods 209 to rotate synchronously, which is beneficial to mixing and stirring different additives inside the mixing tank 201.

Since the resistance plate 208 is fixed at one end of the auxiliary stirring rod 207, and the auxiliary stirring rod 207 is installed on the rotating shaft 206, the liquid generates a reverse acting force on the resistance plate 208. This reverse acting force pushes the rotating shaft 206 to rotate further.

After the stirring is completed, the additives are discharged through the discharge port 210 and conveyed into the inside of the conveying pipeline 301.

[0025] After the additive enters the interior of the conveying pipeline 301, the driving shaft 304 and the auger 305 are rotated by the feeding motor 303, thereby facilitating the conveyance of the additive to the position of the quantitative discharge pipe 307 for quantitative discharge, and the function of quantitative feeding can be achieved. It is connected to the sealing cover 302 through the connecting piece 308, and the lead screw 310 is connected through the moving block 309. The lead screw 310 is rotated by the adjusting motor 311, thereby driving the connecting piece 308, the sealing cover 302 and a part of the auger 305 to be withdrawn from the interior of the conveying pipeline 301, facilitating the exposure of the position of the auger 305 outside, facilitating the cleaning treatment after use, avoiding the accumulation of residues inside, being beneficial to ensuring stable use in the later stage, and avoiding the problem of the mixture of residues and later additive materials resulting in quality decline.

[0026] Embodiment 2: As Figure 2 shown, the support mechanism 4 includes a fixed frame 401. A support ring 404 is arranged inside the fixed frame 401. The support ring 404 is sleeved and installed on the outer wall of the conveying pipeline 301. Support legs 402 are symmetrically and fixedly installed at the bottom of the fixed frame 401. A support base 403 is fixedly installed at the bottom of the support legs 402. A plurality of bolt holes are penetrated through the support base 403.

[0027] In this embodiment, the support ring 404 is sleeved and installed outside the conveying pipeline 301 and cooperates with the fixed frame 401 to provide stable support. The support legs 402 provide erection support, and at the same time cooperate with the support base 403 to provide stable support, ensuring the stability of use and improving the convenience of installation.

During the stirring process, the liquid will generate a reverse acting force on the position of the resistance plate 208, thereby pushing the rotating shaft 206 to rotate further, which is beneficial to driving the auxiliary stirring rod 207 to further stir and mix the additive at the same time. It is beneficial to improve the stirring and mixing effect through multiple refined stirring methods, realizing sufficient stirring, ensuring the uniformity of the additive during quantitative addition, and effectively improving the quality. After the stirring is completed, the additive is discharged through the discharge port 210 and transported into the internal of the conveying pipeline 301. When the additive enters the internal of the conveying pipeline 301, the feeding motor 303 drives the transmission shaft 304 and the auger 305 to rotate, thereby facilitating the transportation of the additive to the position of the quantitative discharge pipe 307 for quantitative discharge, and the function of quantitative feeding can be realized. The connecting piece 308 is connected to the sealing cover 302, and the moving block 309 is connected to the lead screw 310. The adjusting motor 311 is used to drive the lead screw 310 to rotate, thereby driving the connecting piece 308, the sealing cover 302 and a part of the auger 305 to be withdrawn from the internal of the conveying pipeline 301, which is convenient for exposing the position of the auger 305 outside, facilitating the cleaning treatment after use, avoiding the accumulation of residues inside, and being beneficial to ensuring stable use in the later stage.
