[0002] A mixer is a machine used to mix materials. It consists of a horizontally rotating container and a rotating vertical stirring blade. When the molding material is stirred, the container turns left and the blade turns right. Due to the effect of countercurrent, the movement directions of the particles of the molding material intersect, and the chances of contact with each other increase. The countercurrent mixer has a small extrusion force on the material, low heat generation, high stirring efficiency, and more uniform mixing.

[0030] Among them, a mixing shaft 14 is arranged in the middle of the countercurrent mixing barrel 2, and a movable stirring blade 12 is arranged on one side of the mixing shaft 14, and a fixed stirring blade 15 is arranged on one side of the movable stirring blade 12; one end of the mixing shaft 14 is sleeved with the movable stirring blade 12, and the middle of the movable stirring blade 12 is slidably connected to the limiting strip 13, and the middle of the mixing shaft 14 is fixedly connected to the fixed stirring blade 15, and one side of the mixing shaft 14 is fixedly connected to the circular gear 16, such as Figure 1 , 2 As shown in FIG. 3 , by means of the limit bar 13 on the mixing shaft 14, it is convenient to drive the movable stirring blade 12 to rotate, and it is also convenient to reduce the collision between the rising bottom plate 5 and the movable stirring blade 12, which causes damage to the movable stirring blade 12, making the device more practical.

[0031] Among them, the upper end of the countercurrent mixing barrel 2 is provided with a feed port 19, and a bevel gear 20 is provided above the feed port 19, and a storage barrel 22 is provided above the bevel gear 20, and a feed port 19 is opened on one side of the upper end of the countercurrent mixing barrel 2, and the bevel gear 20 is rotatably connected to one side of the feed port 19, and a control port 21 is opened on one side of the bevel gear 20, and the storage barrel 22 is slidably connected to one side of the bevel gear 20, such as Figure 1 , 5 As shown, by arranging the bevel gear 20 at the top of the feed port 19, it is convenient to realize that the bevel gear 20 is driven to rotate by the circular gear 16 when the mixing shaft 14 is stirred, thereby making the device more practical.

[0032] The baffle 6 is arranged at one end of the bottom plate 5 away from the sliding block 4, and the limit block 7 is slidably connected to the middle of the lower end of the countercurrent mixing barrel 2, and the bottom of the return spring 9 is connected to the top of the limit block 7, and one end of the motor 11 is fixedly connected to the cam 10, as shown in FIG. Figure 1 , 2 As shown in FIG. 4 , by providing a reset spring 9, it is convenient to reset the bottom plate 5 and to avoid the bottom plate 5 from tilting when a small amount of material falls on one side of the bottom plate 5, thereby improving the stability of the bottom plate 5 when in use.

[0033] One end of the mixing shaft 14 passes through the middle of the top of the countercurrent mixing barrel 2 and the mounting plate 17 and is fixedly connected to one end of the motor 2 18; one end of the bevel gear 20 is meshed with one side of the circular gear 16, and the storage barrel 22 is fixedly installed in the middle of the top of the bracket 1, and the bottom of the storage barrel 22 overlaps the material control port 21, as shown in FIG. Figure 1 , 3 As shown in FIG. 5 , by setting the bevel gear 20 and the circular gear 16, it is easy to achieve the effect of mixing and feeding at the same time, so that after a small amount of material is mixed evenly, the material can be gradually added for mixing, thereby achieving the effect of improving the mixing efficiency and making the mixer more convenient to use.

[0034] Working principle: When using the device, first place the material to be mixed in the storage barrel 22 red on the bracket 1, and then turn on the motor 2 18 on the mounting plate 17, so that the motor 2 18 drives the mixing shaft 14 to rotate, thereby realizing that the mixing shaft 14 drives the fixed stirring blade 15 and the movable stirring blade 12 to rotate. At the same time, the circular gear 16 drives the bevel gear 20 to rotate, and when the bottom of the storage barrel 22 is aligned with the material control port 21, the material falls into the countercurrent mixing barrel 2 from the feed port 19, and at this time, the fixed stirring blade 15 and the movable stirring blade 12 stir the material.

[0035] Secondly, after the mixture is evenly mixed, the motor 11 can be controlled so that the motor 11 drives the cam 10 to rotate, thereby the cam 10 pushes the bottom plate 5, and the bottom plate 5 slides in the sliding groove 3 through the sliding block 4. When one end of the bottom plate 5 overlaps with the movable stirring blade 12, the movable stirring blade 12 slides on the limit strip 13 on the mixing shaft 14 to make way.

[0036] Finally, the end of the bottom plate 5 close to the cam 10 pushes the baffle 6 up. At this time, the baffle 6 slides on the limit rod 8 through the limit block 7 and contracts the return spring 9. Then, when the material is separated from the countercurrent mixing barrel 2, the bottom plate 5 is reset under the action of the return spring 9.
