[0002] Aluminum coatings are widely used in industrial production to provide corrosion and oxidation resistance to metal surfaces. The adhesion and durability of the coating depend largely on the uniformity of the coating.

[0003] Traditional mixing devices usually put all the raw materials in at once and then stir them. This will cause the raw materials to be obviously stratified in the initial state, requiring more time to mix. In addition, there may still be some areas that may not be stirred properly, resulting in poor mixing effect, causing unstable coating performance. Utility Model Content

Raw materials are added into each independent feed chamber, and the inclined bottom plate allows the raw materials to move to the gap close to the center. On the one hand, the rotating shaft drives the baffle to rotate so that the notch continuously rotates to the bottom of different gaps, and the raw materials in each feed chamber fall at intervals, thereby effectively avoiding the aggregation of a single raw material due to one-time addition, resulting in poor mixing effect and uneven mixing.

A feeding chamber, a feeding hopper communicating with the feeding chamber is arranged on the top of the mixing box, a bottom plate is arranged at the bottom of the feeding chamber, the bottom plate is inclined downward from the inner wall of the mixing box toward the direction of the fixed axis, and there is a gap between the bottom plate and the fixed axis, a motor is arranged on the top of the mixing box, a rotating shaft is arranged on the output shaft of the motor, the rotating shaft passes through the fixed axis and a baffle is arranged below the gap, a notch is opened on the baffle, a plurality of stirring blades are arranged on the rotating shaft below the baffle, and a discharge pipe is arranged at the bottom of the mixing box.

[0006] The utility model is further configured as follows: a plurality of inclined dispersion plates are arranged on the inner wall of the mixing box, and the plurality of dispersion plates are distributed between the baffle plate and the stirring blade in a ring array.

[0007] The utility model is further configured as follows: the stirring blades extend in a spiral shape along the axial direction of the rotating shaft.

[0008] The utility model is further configured as follows: the width of the notch is 1 / 3-1 / 2 of the gap width.

[0009] The utility model is further configured as follows: bearing sleeves are arranged at both ends of the fixed shaft, and the rotating shaft passes through the bearing sleeves and rotates in cooperation with the fixed shaft.

[0010] In summary, the utility model has the following beneficial effects:

[0011] By adding the raw materials into each independent feeding chamber, the inclined bottom plate allows the raw materials to move to the gap close to the center. On the one hand, the rotating shaft drives the baffle to rotate so that the gap continuously rotates to the bottom of different gaps, and the raw materials in each feeding chamber fall down at intervals.

[0020] Additionally, a plurality of inclined dispersion plates 13 are fixedly provided on the inner wall of the mixing box 1, and the plurality of dispersion plates 13 are distributed in a circular array between the baffle 9 and the stirring blades 11. By setting up a plurality of dispersion plates 13, the raw materials are further dispersed in the process of falling, which is beneficial to improving the subsequent mixing effect.

[0021] The stirring blade 11 extends in a spiral shape along the axial direction of the rotating shaft 8. Through the spiral stirring blade 11, the raw materials can be pushed upward and then dropped while stirring. The paint will be better dispersed and mixed during the mixing process, ensuring that the paint composition is uniform and improving the quality of the paint.

[0022] The width of the notch 10 is 1 / 3-1 / 2 of the width of the gap 7. The width of the notch 10 is used to control the speed of material dropping, increase the number of alternating material dropping cycles, and avoid excessively fast material dropping.

[0023] Bearing sleeves 14 are fixedly installed at both ends of the fixed shaft 2, and the rotating shaft 8 passes through the bearing sleeves 14 and rotates with the fixed shaft 2. The setting of the bearing sleeves 14 can reduce the friction between the rotating shaft 8 and the fixed shaft 2, so that the rotating shaft 8 can rotate smoothly, and can ensure that the rotating shaft 8 maintains stable rotation during the stirring process;

[0024] Working principle: When the mixing device is in use, the motor is started, and then a plurality of weighed raw materials are introduced into a plurality of feed chambers 4 through the feed hopper 5 respectively. The inclined setting of the bottom plate 6 will cause the raw materials to move to the gap 7 close to the center, and the motor drives the rotating shaft 8 to rotate. On the one hand, the rotating shaft 8 drives the baffle 9 to rotate, so that the notch 10 on the baffle 9 rotates continuously to the bottom of the gap 7 of different feed chambers 4, and the raw materials in each feed chamber 4 fall at intervals. On the other hand, the rotating shaft 8 drives the stirring blade 11 to rotate, and the falling raw materials are stirred and mixed, and the raw materials first fall to the center of the stirring blade 11, thereby effectively avoiding the aggregation of a single raw material caused by one-time addition, resulting in poor mixing effect and uneven mixing.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
