DETAILED DESCRIPTION

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] A material blocking net 7 is slidably fitted at an opening at one end of the mixing box 1, and a raw material adding mechanism 8 is fixedly connected to one side of the mixing box 1.

[0032] like Figure 3 As shown, the adjustable stirring mechanism 3 includes a stirring rod 301, which is fixedly connected to the stirring shaft 2, and a bidirectional screw rod 302 is rotatably connected inside the stirring rod 301, and an adjusting wheel 303 is connected to one end of the bidirectional screw rod 302 located inside the stirring shaft 2. The bidirectional screw rod 302 realizes the retraction and extension of the stirring blade 306.

[0033] Both ends of the bidirectional screw rod 302 are threadedly connected with an adjusting block 304, an adjusting rod 305 is rotatably connected to the adjusting block 304, and a stirring blade 306 is rotatably connected between the two adjusting rods 305. The stirring blade 306 is suitable for mixing emulsion raw materials.

[0034] like Figure 3 , Figure 4 As shown, the adjustment mechanism 4 includes an electric push rod 401, one end of which is connected and fixed to the inner wall of the stirring shaft 2, and an adjustment ring 402 is connected and fixed to one end of the electric push rod 401. A plurality of adjustment racks 403 are connected and fixed to the bottom of the adjustment ring 402, and the adjustment racks 403 are meshed and driven with the adjustment wheel 303. The adjustment mechanism 4 realizes the adjustment of the stirring blade 306.

[0035] like Figure 5 As shown, the airflow mixing mechanism 5 includes a scraping frame 501, which is connected and fixed to the bottom end of the stirring shaft 2, and an air guide tube 502 is connected and fixed to the middle of the scraping frame 501. A connecting rod 503 is rotatably connected in the air guide tube 502, and both ends of the connecting rod 503 are connected and fixed to an air jet 504, one end of the air jet 504 is rotatably connected to one end of the air guide tube 502, and a motor A505 is connected and fixed to the inner wall of one end of the scraping frame 501, and the motor A505 is connected to one of the air jet tubes 504. The motor A505 drives the air jet tube 504 to rotate, and when the air jet tube 504 is not in use, its air outlet is rotated and retracted to avoid blockage caused by the falling of raw materials.

[0036] like Figure 6, Figure 8 As shown, a motor B601 is connected and fixed at one end of the inflatable seat 6, and the motor B601 is connected and fixed to the mixing box 1 through the motor seat 602. An impeller 603 is rotatably connected and arranged in the inflatable seat 6, and a universal joint 604 is connected and fixed at one end of the impeller 603. The other end of the universal joint 604 passes through the inner wall of the stirring shaft 2 and extends to the outside and is connected and fixed to a transmission wheel 605. The transmission wheel 605 is meshed and arranged with an annular rack 101 connected and fixed on the mixing box 1. The annular rack 101 realizes the function of driving the impeller 603 to rotate and pump air.

[0037] The air inlet end of the inflatable seat 6 is threadedly connected with a filter 606, and the air outlet end of the inflatable seat 6 is connected to the air guide pipe 502. The filter 606 filters the air to ensure the cleanliness of the air.

[0038] like Figure 7 As shown, the material retaining net 7 is arranged in a conical structure, a tension spring 701 is connected between the material retaining net 7 and the mixing box 1, a contact rod 702 is connected and fixed to the bottom end of the material retaining net 7, a plurality of protrusions 201 are connected and fixed to the outer wall of the stirring shaft 2, and the protrusions 201 are arranged in sliding contact with the outer wall of the contact rod 702. The protrusions 201 cooperate with the tension spring 701 to achieve the shaking of the material retaining net 7 to avoid the blockage of the raw materials.

[0039] like Figure 8 As shown, the raw material adding mechanism 8 includes a blocking plate 801, which is connected and fixed to the mixing box 1. The blocking plate 801 is located at the feeding port of the mixing box 1 and has an opening. A turntable 802 is rotatably connected to the blocking plate 801, and a plurality of raw material barrels 803 are connected and fixed to the turntable 802. A motor C804 is connected and fixed to one end of the turntable 802, and the motor C804 is connected and fixed to the blocking plate 801. The blocking plate 801 seals the raw material barrels 803.

[0040] When adding and mixing raw materials for pharmaceutical production and processing, firstly, the motor C804 is used to drive the turntable 802 to rotate, so that the corresponding raw material barrel 803 rotates to the opening of the blocking plate 801, so that the raw materials in the raw material barrel 803 are added to the mixing box 1 for mixing;

[0041] Example 1, when the emulsion raw materials need to be mixed, the electric push rod 401 is used to drive the adjustment ring 402 to move downward, and the adjustment ring 402 will drive the connected adjustment rack 403 to move, so that the adjustment rack 403 will drive the bidirectional screw 302 connected to the adjustment wheel 303 to rotate, so that the bidirectional screw 302 will drive the adjustment block 304 to move, thereby driving the stirring blade 306 connected to the adjustment rod 305 to move out, and then the motor B601 is used to drive the stirring shaft 2 to rotate rapidly, so that the stirring blade 306 can quickly mix the raw materials through shear force;

[0042] In Example 2, when the solid particle raw materials need to be mixed, the motor B601 is used to drive the inflatable seat 6 to rotate. At this time, under the action of the annular rack 101, the transmission wheel 605 is driven to rotate, so that the transmission wheel 605 drives the impeller 603 connected to the universal joint 604 to rotate, and the external air is filtered through the filter 606 and then injected into the air guide pipe 502;

[0043] Then, the motor A505 is used to drive the air jet pipe 504 to rotate, so that the air outlet of the air jet pipe 504 corresponds to the air outlet of the scraper frame 501. At this time, the high-speed airflow injected into the air guide pipe 502 will be ejected through the air jet pipe 504. At this time, when the scraper frame 501 rotates, the solid particles are mixed with the raw materials quickly and evenly in the high-speed fluidized airflow through the shearing and mixing effects of the airflow;

[0044] The air injected into the mixing box 1 will be discharged after filtering the raw materials through the material retaining net 7. At this time, driven by the rotating stirring shaft 2, the connected protruding block 201 will lift the contact rod 702. At this time, the tension spring 701 drives the material retaining net 7 to reset, so that the raw materials attached to the material retaining net 7 can fall down, thereby ensuring the filtering efficiency of the material retaining net 7.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
