[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1 to 3The present invention provides a mixing device for preparing an ointment, comprising a mixing tank 1, a feeding hopper 2 fixedly disposed on one side of the top of the mixing tank 1, an observation window 3 disposed on the front of the mixing tank 1, several support legs fixedly disposed on the side of the bottom of the mixing tank 1, a stirring mechanism 4 disposed at the top of the interior of the mixing tank 1, a pressing mechanism 5 disposed at the bottom of the interior of the mixing tank 1 and connected to the stirring mechanism 4, a leakage mesh plate 6 fixedly connected to the inner side wall of the mixing tank 1 disposed between the pressing mechanism 5 and the stirring mechanism 4, the leakage mesh plate 6 being rotatably connected to the stirring mechanism 4 via a bearing 7, a discharge pipe 8 fixedly disposed on one side of the bottom of the mixing tank 1, a valve 9 disposed on the discharge pipe 8, and an extrusion mechanism 10 fixedly disposed on the side of the mixing tank 1, matching the pressing mechanism 5 and inserted into the mixing tank 1;

[0030] In use, the raw materials are poured into the mixing tank 1 through the feed hopper 2, and the stirring mechanism 4 is started to mix the raw materials. During the stirring process, the raw materials at the bottom will penetrate the material leakage mesh plate 6 and enter the bottom of the pressing mechanism 5. As the stirring mechanism 4 rotates, it will simultaneously drive the pressing mechanism 5 to perform a cyclic pressing operation. The pressing mechanism 5 presses the raw materials into the extrusion mechanism 10, and then the extrusion mechanism 10 extrudes the raw materials and discharges them to the top of the mixing tank 1, so as to achieve full material turning and improve the uniformity and efficiency of mixing.

[0031] Example 2, based on Example 1, is... Figures 1 to 5The mixing mechanism 4 is described as follows: a drive motor 11, a mixing main shaft 12, several main mixing blades 13, several main mixing blades 14, a scraping assembly 15, a rotating support disk 16, an internal gear ring 17, a local mixing assembly 18, and a local mixing assembly 19. The drive motor 11 is fixedly connected to the middle position at the top of the mixing tank 1. The mixing main shaft 12 is rotatably connected to the middle position inside the mixing tank 1 and fixedly connected to the output shaft of the drive motor 11. The main mixing blades 13 and 14 are both fixedly connected to the side of the mixing main shaft 12. The rotating support disk 16 is sleeved on the top of the mixing main shaft 12 and fixedly connected to it. The scraping assembly 15 is fixedly connected to the side of the bottom end of the rotating support disk 16. The internal gear ring 17 is fixedly connected to the top of the inner side wall of the mixing tank 1. The local mixing assembly 18 and 19 are... Both the second local stirring assembly 19 and the first local stirring assembly 18 are connected to the rotating support disk 16 and matched with the internal gear ring 17. Both the first local stirring assembly 18 and the second local stirring assembly 19 are composed of a gear 20, a driven stirring shaft 21 and several local stirring blades 22. The gear 20 is rotatably connected to the side inside the rotating support disk 16 and meshes with the internal gear ring 17. The driven stirring shaft 21 passes through the rotating support disk 16 and is fixedly connected to the gear 20. The local stirring blades 22 are fixedly connected to the side of the driven stirring shaft 21. The scraping assembly 15 is composed of a support arm 23, a scraper 24 and a flexible scraper 25. The support arm 23 is fixedly connected to the side of the bottom end of the rotating support disk 16. The scraper 24 is fixedly connected to the other end of the support arm 23. The flexible scraper 25 is fixedly connected to the side of the scraper 24 and is attached to the inner wall of the mixing tank 1.

[0032] When the stirring mechanism 4 is working, the driving motor 11 drives the stirring main shaft 12 to rotate. The driving motor 11 and the stirring main shaft 12 drive the main stirring blade 13, the main stirring blade 14, the scraping assembly 15 and the rotating support disk 16 to rotate synchronously. The main stirring blade 13 and the main stirring blade 14 achieve comprehensive stirring. The scraping assembly 15 scrapes the inner wall of the mixing tank 1. During the rotation of the rotating support disk 16, the local stirring assembly 18 and the local stirring assembly 19 move synchronously. The local stirring assembly 18 and the local stirring assembly 19 achieve comprehensive stirring. At this time, the gear 20 meshes with the internal gear ring 17 and rotates relative to each other. The gear 20 drives the driven stirring shaft 21 and the local stirring blade 22 to rotate, achieving local stirring. By alternately setting the main stirring blade 13 and the main stirring blade 14 with the local stirring assembly 18 and the local stirring assembly 19, the uniformity and efficiency of stirring can be effectively improved.

[0033] Example 3, based on Example 1, is... Figures 1 to 7The pressing mechanism 5 consists of a twisted shaft 26, an auxiliary support 27, a pressing plate 28, a follower component 29, several adaptive sealing components 30, and several limiting guide rods 31. The twisted shaft 26 is fixedly connected to the bottom end of the mixing main shaft 12. The auxiliary support 27 is fixedly connected to the middle position of the bottom end inside the mixing tank 1 and is rotatably connected to the twisted shaft 26. The pressing plate 28 is sleeved on the twisted shaft 26. A through groove 32 is opened at the center position of the pressing plate 28. The follower component 29 is fixedly connected to the inner side wall of the through groove 32 and is connected to the twisted shaft 26. Several leakage grooves 33 are opened on the pressing plate 28. The adaptive sealing components 30 are connected to the bottom end of the pressing plate 28 and match the leakage grooves 33. The limiting guide rods 31 are fixedly connected to the bottom end of the mixing main shaft 12. The side of the bottom of the mixing tank 1 is attached to the pressure plate 28 and slides through it. The side edge of the pressure plate 28 is slidably connected to the inner wall of the mixing tank 1. The follower component 29 consists of a mounting base 34, a movable rotating shaft 35 and an arc-shaped swing head 36. The mounting base 34 is fixedly connected to the inner wall of the through groove 32. The arc-shaped swing head 36 is rotatably connected to the mounting base 34 through the movable rotating shaft 35. The arc-shaped swing head 36 is engaged with the twisted groove on the surface of the twisted shaft 26. The adaptive sealing component 30 consists of a limiting shaft seat 37, a sealing plate 38 and a rubber pad 39. The sealing plate 38 is rotatably connected to the pressure plate 28 through the limiting shaft seat 37. The included angle between the sealing plate 38 and the pressure plate 28 is 35 degrees. The rubber pad 39 is fixedly connected to the top of the sealing plate 38.

[0034] During the rotation of the mixing spindle 12, the twisted shaft 26 is driven to rotate synchronously. At this time, the arc-shaped oscillating head 36 follows the rotation of the twisted shaft 26 and performs up-and-down reciprocating motion. The movable shaft 35 can improve the mobility of the arc-shaped oscillating head 36, so that the arc-shaped oscillating head 36 can automatically change direction while rotating with the twisted shaft 26, thereby realizing reciprocating lifting and lowering motion. The mounting base 34 is fixedly connected to the pressure plate 28, thereby driving the pressure plate 28 to move up and down. The limit guide rod 31 can realize the vertical limit of the pressure plate 28, improving the stability of the movement of the pressure plate 28. When pressed down, the sealing plate 38 rotates around the limiting shaft 37 due to the resistance of the raw material at the bottom, thus sealing the material leakage trough 33 and preventing the raw material from being discharged upward through the material leakage trough 33. At this time, the material is pressed into the extrusion mechanism 10 by the pressure plate 28. When the pressing is completed, the pressure plate 28 moves upward, and the sealing plate 38 automatically swings down due to its own gravity. The raw material at the top passes through the material leakage trough 33 due to its own gravity and enters the bottom of the pressure plate 28, preparing for the next pressing. By repeating the above operation, continuous pressing can be achieved without the need for an additional power source, thus improving the convenience of use.

[0035] Example 4, based on Example 1, is... Figure 2 , Figure 3 , Figure 8 and Figure 9The extrusion mechanism 10 consists of an L-shaped extrusion pipe 40, a first valve 41, a diversion pipe 42, a second valve 43, an annular pipe 44, several feeding pipes 45, and several mixers 46. The L-shaped extrusion pipe 40 is fixedly connected to the bottom end of one side of the mixing tank 1. The first valve 41 is connected to the L-shaped extrusion pipe 40. The annular pipe 44 is sleeved on the bottom end of the outer surface of the mixing tank 1 and fixedly connected to the L-shaped extrusion pipe 40 through the diversion pipe 42. The second valve 43 is connected to the diversion pipe 42. The feeding pipe 45 is fixedly connected to the top end of the annular pipe 44 and inserted into the top end of the side of the mixing tank 1. The mixers 46 are connected to the middle position of the feeding pipe 45. Both pipe 45 and mixer 46 are fixedly connected to mixing tank 1 via reinforcing base 47. Mixer 46 consists of sleeve 48, inner tube 49 and diversion sleeve 50. Inner tube 49 is fixedly connected to the bottom end inside sleeve 48 and fixedly connected to feed pipe 45. Diversion sleeve 50 is fixedly connected to the top end of inner tube 49 and located in the middle position inside sleeve 48. Several side holes 51 are opened at the top end of the side of inner tube 49. Main channel 52 is formed inside diversion sleeve 50. Several diversion holes 53 are opened on the side of diversion sleeve 50. A return chamber 54 communicating with side holes 51 and diversion holes 53 is formed between the outer surface of diversion sleeve 50 and sleeve 48.

[0036] The extruded raw material enters the interior of the L-shaped extrusion tube 40. At this time, valve 1 41 is closed and valve 2 43 is open, allowing the raw material to enter the interior of the diversion tube 42. Through the diversion tube 42, it enters the interior of the annular tube 44, and through the annular tube 44, it enters the interiors of multiple feeding tubes 45. Through the feeding tubes 45, the raw material is discharged back into the top of the mixing tank 1, realizing the material turning operation. When the raw material passes through the mixer 46, it can achieve automatic mixing. At this time, the raw material enters the inner tube 49 and is discharged along the top of the inner tube 49. The raw material enters the interior of the diversion sleeve 50. At this time, some of the raw material will enter the interior of the return chamber 54 through the diversion hole 53. Since the interior of the return chamber 54 is not subjected to upward pressure or the pressure is very small, the raw material in the return chamber 54 will flow downward and enter the inner tube 49 through the side hole 51, realizing mixing with the newly entered raw material. During the extrusion process, continuous mixing operation can be achieved, further improving the uniformity of mixing. After the mixing is completed, valve 1 41 and valve 3 9 are opened to discharge the material.

[0037] In operation, the mixing mechanism, consisting of a drive motor, a stirring shaft, several main stirring blades, several main stirring blades, a scraping assembly, a rotating support disc, an internal gear ring, and two local stirring components, enables thorough mixing of raw materials. It combines local and overall mixing, thereby improving the uniformity and efficiency of the mixture. The pressing mechanism, composed of a twisted shaft, auxiliary support, pressure plate, follow-up assembly, several self-adaptive sealing components, and several limit guide rods, automatically reciprocates and lifts with the rotation of the stirring shaft, achieving pressing operation. The extrusion mechanism, consisting of an L-shaped extrusion pipe, valve one, a diversion pipe, valve two, an annular pipe, several feeding pipes, and several mixers, works in conjunction with the pressing mechanism to re-extract the pressed raw materials into the mixing tank, achieving a material turning operation. Finally, the mixer, consisting of a sleeve, an inner tube, and a diversion sleeve, ensures that the raw materials are uniformly mixed again during extrusion, further improving mixing uniformity and efficiency.
