The material tray 150 guides the falling materials, and the hollow structure reduces the weight of the material guide tray 150, reduces the pressure on the stirring shaft 120, and greatly improves the service life of the mixing mechanism 100. The material guiding operation is achieved through the material guide tray 150, which solves the problem that during the feeding process of the current mixing device, the materials fall along the same position due to the lack of the material guide tray 150 to guide the materials entering the mixing barrel 110, and the materials will be directly scattered onto the stirring shaft 120, resulting in the possibility of some materials being accumulated on the stirring shaft 120 and difficult to be evenly stirred by the stirring blades 130. The scraper assembly 140 is used to scrape off the residual materials on the inner side of the mixing barrel 110, thereby avoiding unnecessary waste of materials, greatly saving the time of material mixing, and achieving a better mixing effect.

[0018] According to one embodiment of the utility model, Figure 1 and Figure 2As shown, a discharge port 160 is provided at the bottom of the outer wall of the vertical portion of the mixing barrel, and a discharge hopper 170 is provided on the outer wall of the mixing barrel outside the discharge port 160. An opening and closing assembly 180 for opening and closing the discharge port 160 is provided inside the discharge hopper 170. The opening and closing assembly 180 includes a telescopic push rod 181 provided on the side wall of the discharge hopper 170. The telescopic push rod 181 is an electric telescopic rod or a hydraulic telescopic rod. The output rod of the telescopic push rod 181 passes through the outer wall of one side of the discharge hopper 170. A fixing plate 182 is provided at the end of the output rod of the telescopic push rod 181. A baffle plate 183 adapted to the discharge port 160 is provided on the inner side of the fixing plate 182. The new type can push the baffle plate 183 to block the discharge port 160 when the output rod of the telescopic push rod 181 is extended, and then cooperate with the stirring shaft 120 of the mixing barrel 110 to fully mix and stir the materials in the mixing barrel 110 under the drive of the rotation of the output shaft of the driving motor. After the mixing and stirring is completed, the output rod of the telescopic push rod 181 is started to retract the baffle plate 183 away from the discharge port 160. At this time, the evenly mixed material will be thrown out along the discharge port 160 due to the action of the stirring blade 130 due to the centrifugal force, and finally fall through the discharge hopper 170 and be collected by the collection bucket pre-placed at the bottom of the discharge hopper 170, which is more convenient to operate.

[0020] The use of the utility model:

[0021] First of all, it should be clear that the mixing device involved in the utility model is mainly used for mixing powder materials. The utility model takes the mixing of powder raw materials of cardiovascular medicine as an example to explain its use method in detail. When the powder raw materials need to be mixed, first start the output shaft of the drive motor to rotate, and at the same time start the output rod of the telescopic push rod 181 to extend, and push the baffle plate 183 to block the discharge port 160 when the output rod of the telescopic push rod 181 is extended. Then, the material to be mixed is introduced into the mixing barrel 110 from the upper part of the mixing barrel 110, and the guide plate 150 with a conical dome-shaped hollow structure realizes the mixing of the powder raw materials. The output shaft of the motor can drive the stirring shaft 120 in the mixing barrel 110 to carry the stirring blades 130 to fully mix and stir the materials in the mixing barrel 110. When the output shaft of the driving motor drives the stirring shaft 120 to rotate, the fixing rod 141 will also drive the fixing seat 142 and the scraper 143 to rotate along the stirring shaft 120. Under the action of the torque force of the torsion spring, the scraper 143 can be pushed to always contact the inner wall of the mixing barrel 110, thereby realizing the scraping and cleaning operation of the materials adhered to the inner wall of the mixing barrel 110. After the mixing is completed, the telescopic push rod 141 is started. The output rod of the rod 181 is retracted, and the output rod of the telescopic push rod 181 is retracted until the baffle plate 183 is retracted away from the discharge port 160. At this time, the evenly mixed material will be thrown out along the discharge port 160 due to the centrifugal force under the action of the stirring blade 130, and finally fall through the discharge hopper 170 and be collected by the collection bucket pre-placed at the lower part of the discharge hopper 170. The utility model can guide the falling material through the guide plate 150 with a conical dome-shaped hollow structure, and the hollow structure reduces the weight of the guide plate 150, reduces the pressure on the stirring shaft 120, and greatly improves the mixing mechanism 100. The service life of the material is prolonged, and the material is guided by the guide plate 150, which solves the problem that the material in the current mixing device lacks the guide plate 150 to guide the material entering the mixing barrel 110 during the feeding process, causing the material to fall along the same position, and the material will be directly scattered onto the stirring shaft 120, resulting in the possibility of some material being accumulated on the stirring shaft 120, and it is difficult to be evenly stirred by the stirring blades 130. The scraper assembly 140 can be used to scrape off the residual material on the inner side of the mixing barrel 110, thereby avoiding unnecessary waste of material, greatly saving the time of material mixing, and achieving a better mixing effect.
