Description

Technical Field

[0001] The utility model relates to the technical field of powder mixing, in particular to a stirring component, a feed box and a dry granulator. Background Art

[0002] In the field of powder mixing, agitators are often used. Existing horizontal agitators often use spiral blades, which are driven by a rotating shaft to stir and mix the powder. However, when the pitch of the spiral blades is small, the powder is easy to adhere between the spiral blades, causing the spiral agitator to form a cylindrical rotating body, and eventually lose the stirring and mixing effect on the material. In order to eliminate the above problems, a common method is to increase the pitch between the spiral blades, thereby reducing the clamping force of the blades on the material. However, for powders with low density and strong adsorption, the powder is still easy to adhere between the blades. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] Combine the following Figure 1 , describing an embodiment of the utility model.

[0027] According to an embodiment of the utility model, in a first aspect, a stirring assembly is provided, comprising: a stirring paddle 10, a pendulum structure 20 and a first rotating shaft 30. The stirring paddle 10 comprises a helical ribbon blade 11, and a plurality of the helical ribbon blades 11 are provided, and the plurality of the helical ribbon blades 11 are connected in sequence; the pendulum structure 20 is connected to the stirring paddle 10, and the pendulum structure 20 is arranged between two adjacent helical ribbon blades 11, and the pendulum structure 20 comprises a pendulum 21, and the pendulum 21 is rotatably arranged; the first rotating shaft 30 is transmission-connected to the stirring paddle 10, and the stirring paddle 10 is arranged around the first rotating shaft 30.

[0028] The stirring assembly of this embodiment is applied, by setting a pendulum structure 20 between adjacent spiral blades 11, and the powder material adhering to the spiral blades 11 is beaten by the continuous rotation of the pendulum 21, thereby destroying the static state of the powder material between the spiral blades 11, so that the powder material falls off from between the blades, thereby solving the problem of material adhering to the spiral blades 11.

[0029] Specifically, in this embodiment, a plurality of spiral blades 11 are integrally formed.

[0030] Of course, in other alternative implementations, the pendulum 21 may be configured to be oscillating, and the oscillation of the pendulum 21 may also destroy the static state of the powder material between the spiral blades 11 .

[0031] It should be noted that, compared with setting the pendulum 21 to be able to swing, setting the pendulum 21 to be able to rotate has a larger range of motion for the pendulum 21 and a better effect on preventing the powder material from adhering between the blades.

[0032] It is worth noting that, by using the stirring assembly of this embodiment, the effect of preventing the powder material from adhering between the spiral blades 11 can be achieved without adjusting the pitch between the spiral blades 11 .

[0035] It should be noted that the stirring assembly in this embodiment is a horizontal stirring assembly.

[0036] It is worth noting that by eccentrically setting the pendulum 21, when the first rotating shaft 30 rotates, the pendulum 21 makes non-uniform eccentric rotation around the second rotating shaft 22 under the action of gravity, without the need for external energy drive; the pendulum 21 achieves multi-directional disturbance of the powder material through eccentric rotation, thereby improving the mixing effect of the agitator on the material.

[0037] In other alternative embodiments, the stirring assembly further includes a driving structure, which drives the pendulum 21 to rotate around the second rotation axis 22 .

[0045] It is worth noting that, by providing the support column 12, the spiral ribbon blade 11 is supported, the structural strength of the stirring assembly is improved, and the stability of the spiral ribbon blade 11 when stirring the powder material is improved.

[0046] In one embodiment, the axis of the support column 12 is perpendicular to the axis of the first rotation shaft 30 .

[0047] Of course, in other alternative embodiments, the axis of the support column 12 and the axis of the first rotation axis 30 may also be arranged at other angles.

[0048] It is worth noting that the support column 12 is vertically arranged to the first rotating shaft 30 , and the support column 12 transmits longitudinal force to the helical blade 11 to ensure the lateral stability of the helical blade 11 .

[0049] In one embodiment, Figure 1 As shown, a plurality of support columns 12 are provided, one end of each of the support columns 12 is respectively connected to a plurality of spiral blades 11 , and the other ends of each of the support columns 12 are connected to the first rotating shaft 30 .
