[0035] The working principle of the multi-channel mixing and stirring device is as follows: firstly, the solid material to be mixed is added from the top end of the processing shell 119, at the same time, the threads on the mixing storage tank 201 are aligned with the mixing rotating shell 208, and the mixing rotating shell 208 is rotated to make the mixing storage tank 201 close to the mixing rotating shell 208, at this time, the mixing top rod 204 pushes the mixing blocking ball one 203 and the mixing blocking ball two 205, the liquid channel is opened, and the liquid flows into the mixing valve fixed shell 211.

[0036] The processing motor 115 is started, the processing motor 115 drives the processing belt 113 and the processing cam 112 to rotate; the processing belt 113 drives the processing bevel gear three 114 to rotate, the processing bevel gear three 114 drives the processing bevel gear one 101 to rotate, the processing bevel gear one 101 drives the processing bevel gear two 107, the processing scattering ring 108, the processing gear 106, the processing fixed sheet 103, the processing gear ring 105 and the processing ball 104 arranged on the processing fixed support 102 to rotate around the center of the processing bevel gear one 101, at the same time, the processing bevel gear two 107 meshes with the fixed processing fixed bevel gear 116 to make the processing bevel gear two 107 rotate, the processing bevel gear two 107 drives the processing scattering ring 108 and the processing gear 106 to rotate, the processing scattering ring 108 rotates and revolves to scatter the raw materials in the processing shell 119, preventing the materials from caking, at the same time, the processing gear 106 drives the processing gear ring 105 to rotate, the processing gear ring 105 drives the processing ball 104 to rotate, when the processing ball 104 rotates, the fan blades arranged on the processing ball 104 release the charged ions generated by the processing ball 104 to the surrounding air to neutralize the static charge on the surface of the materials, thereby eliminating the static electricity on the materials and preventing the subsequent mixing from sticking.

[0037] At the same time that the processing cam 112 rotates, the processing connecting rod one 117 and the processing connecting rod two 118 are driven, and the processing cover plate one 109 and the processing cover plate two 110 intermittently touch the processing outlet one 120 and the processing outlet two 121, when the processing cover plate one 109 is far away from the processing outlet one 120, the materials in the processing shell 119 fall into the processing outlet two 121 through the processing outlet one 120, when the processing cover plate one 109 is in the closed position, the processing cover plate two 110 is in the open state, at this time, the materials in the processing outlet two 121 fall into the mixing shell 212 through the pipeline, and the rotation of the processing motor 115 realizes the accurate control of the material quantity.

[0038] When the mixed materials fall into the mixing shell 212, the mixing motor 216 is started, the mixing motor 216 drives the mixing flywheel 213 to rotate, the mixing flywheel 213 drives the mixing disc 214 to deflect, the mixing disc 214 deflects to make the mixing sliding rod 210 slide, the mixing sliding rod 210 slides to drive the mixing blocking ball three 209, the mixing blocking ball three 209 is opened with the channel formed by the mixing valve fixed shell 211, at this time the liquid in the mixing valve fixed shell 211 is injected into the mixing shell 212 through the hole on the mixing sliding rod 210, and falls into the stirring part 3 through the hole on the mixing fixed net 215, and waits for stirring.

[0039] When the solid material and the liquid material fall into the stirring shell 304, the stirring motor 306 is started, the stirring motor 306 drives the stirring rotating ring 305 to rotate, the stirring rotating ring 305 rotates to set the fan blades to fully stir the materials, at the same time, the stirring rotating ring 305 rotates to drive the stirring turnover piece 303 to rotate, the stirring turnover piece 303 rotates to contact the stirring limiting plate 302, when the stirring limiting plate 302 contacts the stirring turnover piece 303, the inclined surface on the stirring turnover piece 303 forces the stirring turnover piece 303 to overturn with the groove on the stirring fixed disc 301, which uniformly stirs the materials deposited at the bottom of the stirring shell 304 and prevents the materials from adhering to the bottom of the stirring shell 304. When the materials are completed, the valve on the stirring shell 304 is opened, and the materials are taken out to complete the mixing.

[0040] The above working mode is the working principle of the device for mixing solid and liquid.

[0041] When it is necessary to mix solid materials with solid materials, the operator does not need to install the mixing storage tank 201 on the mixing rotating shell 208, and the remaining working principle is the same as above.

[0042] When it is necessary to mix liquid materials with liquid materials, the processing part 1 does not work, only the mixing storage tank 201 needs to be installed on the mixing rotating shell 208, and the remaining working principle is the same as above.
