Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a technical solution: a mixing device for producing eye ointment, including a frame 1 and a mixing tank assembly 2. The mixing tank assembly 2 includes a cover plate 21 and a tank body 22. The cover plate 21 is fixed on the frame 1. A large gear 28 is fixedly sleeved on the tank body 22 and is rotatably connected to the frame 1. The tank body 22 is driven by a drive assembly 4. A stirring assembly 3 is provided on the cover plate 21. The stirring assembly 3 includes a first motor 31. The output shaft of the first motor 31 is fixedly connected to a stirring rod 32. The stirring rod 32 is provided with a spiral stirring blade 33, an anchor frame 34, and a connecting rod 35. The spiral stirring blade 33 is configured as a spiral linear structure. One end of the connecting rod 35 is fixedly connected to a scraper 36. The connecting rod 35 and the scraper 36 are welded and fixedly connected.

[0025] While the mixing component 3 rotates to mix the materials, the tank 22 itself can rotate under the drive of the drive component 4. The rotation of the mixing component 3 generates axial flow, and the reverse rotation of the tank 22 forms circumferential flow. The two superimposed form a spiral vortex, which expands the mixing range. The high-speed rotation of the mixing component 3 applies high shear force to the materials, and the reverse rotation of the tank 22 peels off the attached layer, reducing the boundary layer thickness, thereby improving the mixing efficiency and mixing quality. The mixing component 3 is driven by the first motor 31, and the tank 22 is driven by the second motor 41. The motors are independently set and support independent speed adjustment.

[0026] The scraper 36 contacts the inner wall of the tank 22. When the scraper 36 moves in a circular motion relative to the tank 22, it scrapes off the material adhering to the inner wall of the tank 22.

[0027] When the first motor 31 drives the stirring rod 32 to rotate, the stirring rod 32 drives the connecting rod 35 to move, and the connecting rod 35 drives the scraper 36 to move. The scraper 36 rotates in the opposite direction to the tank 22, and at the same time scrapes off the material adhering to the inner wall of the tank 22. The shape of the scraper 36 fits the inner wall of the tank 22, and it can achieve complete scraping during rotation, reduce material adhesion, and improve the uniformity of mixing.

[0028] The spiral mixing blade 33 is located above the anchor frame 34, and the spiral mixing blade 33 and the anchor frame 34 work together to mix the material.

[0029] The mixing assembly 3 integrates the spiral mixing blades 33 and the anchor frame 34. When the spiral mixing blades 33 and the anchor frame 34 rotate, the spiral mixing blades 33 generate strong axial flow, which promotes the circulation of materials between the upper and lower layers. Together with the anchor frame 34 structure, the materials are mixed and blended to improve the uniformity of the mixture.

[0030] The cover plate 21 is provided with a feed inlet 23, which is connected to the feeding system. The number of feed inlets 23 can be selectively set according to actual usage requirements. The feeding system is used to transport materials to be mixed. Multiple materials enter the tank 22 through the feed inlet 23, are mixed in the tank 22, and are mixed under the stirring of the stirring component 3.

[0031] The drive assembly 4 includes a second motor 41, which is mounted on the frame 1, and the output shaft of the second motor 41 is fixedly connected to a pinion 42.

[0032] Among them, the small gear 42 meshes with the large gear 28, the large gear 28 is the driven gear, and the small gear 42 is the driving gear. The small gear 42 is driven to rotate by the second motor 41.

[0033] When the second motor 41 is working, it drives the small gear 42 at one end to rotate. Through the meshing transmission between the teeth, it drives the large gear 28 to rotate. The large gear 28 drives the tank 22 fixed to it to rotate. The cover plate 21 is fixed and the rotation direction of the tank 22 is opposite to the rotation direction of the stirring assembly 3.

[0034] The tank body 22 is equipped with a guide bucket 25 at the bottom. The guide bucket 25 has a conical structure. The inclined part of the scraper 36 is adapted to the conical structure of the guide bucket 25, which can scrape the material on the inner wall of the guide bucket 25 and play a guiding role. The mixed material after mixing will be concentrated at the bottom of the tank body 22, which is conducive to material discharge.

[0035] The lower end of the guide bucket 25 is provided with a discharge pipe 26, and a valve 27 is installed on the discharge pipe 26. When the valve 27 is opened, the discharge pipe 26 is opened, and the material can be discharged through the discharge pipe 26. When the valve 27 is closed, the discharge pipe 26 is closed.

[0036] The lower end face of the cover plate 21 is welded and fixed with a connecting edge 24. The connecting edge 24 is connected to the tank body 22 through a bearing. The cover plate 21 and the tank body 22 are connected through a bearing. The tank body 22 can rotate relative to the cover plate 21 under the drive of the drive component 4. The cover plate 21 is fixed and will not interfere with the feeding system.

[0037] Working principle: During use, the feed inlet 23 of the mixing tank assembly 2 is connected to the feeding system, which is used to transport the materials to be mixed. Multiple materials enter the tank body 22 through the feed inlet 23 and are initially mixed in the tank body 22. During the mixing process, the first motor 31 works, driving the stirring rod 32 at one end to rotate. The stirring rod 32 drives the spiral stirring blades 33, anchor frame 34 and connecting rod 35 fixed to it to rotate synchronously. The connecting rod 35 drives the scraper 36 to move. At the same time, the second motor 41 works, driving the small gear 42 at one end to rotate. Through the meshing transmission between the teeth, it drives the large gear 28 to rotate. The large gear 28 drives the tank 22, which is fixed to it, to rotate. The cover plate 21 remains stationary. The rotation direction of the tank 22 is opposite to that of the stirring component 3. The rotation of the stirring component 3 generates axial flow, and the tank 22 rotates in the opposite direction to form circumferential flow. The two superimpose to form a spiral vortex, which expands the mixing range. The scraper 36 rotates in the opposite direction relative to the tank 22, and at the same time scrapes off the material adhering to the inner wall of the tank 22. The shape of the scraper 36 fits the inner wall of the tank 22, and it can achieve complete scraping during rotation, reduce material adhesion, and improve the uniformity of mixing. After the mixing is completed, the valve 27 is opened and the material is discharged through the discharge pipe 26.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
