[0025] In order to control the material discharge speed of the feed chamber, feed rollers 604 are rotatably installed on the inner walls of several feed ports, and feed blocks are protruding outside the feed rollers 604. A guide plate 603 is fixedly connected to the bottom of the inner wall of the feed chamber, and the top of the guide plate 603 is inclined, and the height is lower on the side facing the feed port.

[0032] The method of improving the mixing uniformity of the post-mixing component 3 in the present application is mainly as follows: both sides of the inner wall of the machine 101 are provided with adjustment components 4 for adjusting the posture of the mixing tank 301, see Figure 5The adjusting component 4 includes an adjusting motor 401, the output end of the adjusting motor 401 is fixedly connected to a mounting frame 402, both ends of the mounting frame 402 are fixedly connected to shift supporting rings 404, the inner wall of the shift supporting ring 404 is slidably connected to the stirring tank 301, a shift cylinder 403 is fixedly installed in the middle of the mounting frame 402, and the output end of the shift cylinder 403 is fixedly connected to the middle of the stirring tank 301 through a fixing frame 405; the outer wall of the stirring tank 301 is provided with a shift slide groove 309 for the shift supporting ring 404 to slide. During the stirring process, the adjustment component 4 is used to change the posture of the stirring tank 301, thereby changing the distribution position of the material in the stirring tank 301, so that the stirring element can fully contact the material at different positions, thereby improving the stirring effect of the mixture; specifically, the present application drives the mounting frame 402 to rotate back and forth as a whole within a certain angle by adjusting the motor 401, thereby driving the stirring tank 301 to rotate as a whole, and cooperates with the shift cylinder 403 to drive the stirring tank 301 to move, change the contact position between the shift support ring 404 and the stirring tank 301, and then change the rotation center of the stirring tank 301, so that the rotation centrifugal force of the material at different positions in the stirring tank 301 is different during the rotation process, and then the centrifugal force can be adjusted by changing the rotation center to achieve more effective and uniform dispersion of the material; taking the angle between the mounting frame 402 and the horizontal position as the 0 degree reference line, in the present application, the angle range of the mounting frame 402 driven by the adjustment motor 401 to rotate as a whole is between -40 degrees and 40 degrees.

[0034] If a thin or sharp stirring blade 305 is used, it will cut the liquid when moving at high speed, increasing the surface area of ​​the liquid, making it easier for the gas dissolved in the liquid to precipitate and form bubbles. At the same time, these shapes may also cause increased local turbulence in the liquid, further promoting the formation of bubbles, which is not conducive to sufficient stirring and also affects the quality of the output stirred product.

[0035] The stirring blade 305 is configured as a hemispherical thin sheet, and the smooth curved surface can reduce the cutting of the liquid and local turbulence, thereby reducing the possibility of bubble generation; it helps to make the liquid flow more smoothly and reduce the formation and accumulation of bubbles; through openings are opened on both sides of the stirring blade 305, and the inner wall edges of the through openings are configured as arc-shaped surfaces to reduce the resistance of the material when passing through the through openings; in order to improve the ability of gravity to adjust the posture of the stirring blade 305, a counterweight block is fixedly connected to the bottom of the stirring blade 305, and the traction force of the stirring blade 305 and the counterweight block is used to drive the stirring blade 305 to rotate.

The material is received by the weighing frame 606 of the weighing component. After quantitative weighing by the weighing sensor 607, the weighing frame 606 is driven to flip by the flip motor 605 to send the material downward. The diverter plate 612 of the diverter component then receives the diverter and cooperates with the diverter motor 613 to drive the diverter plate 612 to rotate to one side.
