Description

Technical Field

[0001] This utility model relates to the field of emulsification technology for topical preparations, specifically a vacuum emulsification device for the production of topical preparations. Background Technology

[0002] Topical drug preparations refer to non-invasive drug dosage forms that are applied directly to the skin or mucous membrane surface and achieve therapeutic purposes through local absorption or systemic action.

[0003] In the production of topical pharmaceutical preparations, vacuum emulsification devices are indispensable equipment. However, during use, materials often adhere to the inner walls of these devices, requiring cleaning. A search reveals that patent CN221062481U discloses a vacuum emulsification device for topical preparations, specifically describing: "An emulsification tank, with a sealing cover fixedly installed on its top, a vacuum pipe fixedly installed on the top of the sealing cover, a stirring rod inside the emulsification tank, an installation rod fixedly installed on the stirring rod, an adjustment mechanism at one end of the installation rod, the adjustment mechanism including an installation box, a first slider slidably installed inside the installation box, a second slider slidably installed inside the installation box, an installation groove on the installation box, a connecting block fixedly installed on the top of the second slider, the connecting block located within the installation groove, and an installation plate on the top of the installation box; this invention facilitates the cleaning of materials of varying viscosities adhering to the inner wall of the emulsification tank, reduces material waste, and facilitates cleaning of the emulsification tank."

[0004] Through the search of the above-mentioned solutions and technologies, we found that there are still some defects in the use of this solution. The cleaning of the inner wall of the emulsification tank is achieved by the scraping action of the second scraper. When adjusting the distance between the second scraper and the inner wall of the emulsification tank to clean materials of different viscosity, since the adjustment structure consists of a mounting rod, a mounting box and a fixing block, etc., which are located inside the tank, it means that the sealing cover needs to be opened and the stirring rod needs to be removed for convenient adjustment. This method is relatively cumbersome and troublesome to operate, and it is difficult to achieve convenient and timely adjustment. Utility Model Content

[0014] As a further embodiment of this utility model: the top of the fixed cover is also provided with a feed pipe and a vacuum pipe, and the bottom of the emulsifying tank body is provided with a discharge pipe, and the discharge pipe has a valve.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] I. In this application, through the designed rotating rod, threaded rod, pushing disc, fixed rod, movable rod, and main cleaning scraper, the distance between the main cleaning scraper and the auxiliary cleaning scraper and the inner wall of the emulsifying tank can be easily adjusted by the operator directly on the outside of the emulsifying tank body by turning the threaded rod.

[0025] 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.

[0026] Please see Figure 1-5 A vacuum emulsification device for producing topical preparations includes an emulsification tank body 1 and a fixed cover 2. A rotating rod 5 extending into the emulsification tank body 1 is rotatably connected to the top center of the fixed cover 2 via a sealed bearing. Multiple stirring blades 13 are fixed on the rotating rod 5 at a position between two fixed rods 10, with the stirring blades 13 spaced apart from each other. Two fixed rods 10 are fixed to the rotating rod 5, with a main cleaning scraper 11 at one end of each fixed rod 10 and a secondary cleaning scraper 12 fixed to the bottom of the main cleaning scraper 11. A threaded rod 7 is threadedly connected internally to the rotating rod 5, and two pusher discs 701 are fixed to the rod body of the threaded rod 7. Two movable cavities 501 are provided for the movement of the two push disks 701. The push disks 701 are designed to be elliptical. When the rotating rod 5 rotates downward, it pushes the main cleaning scraper 11 and the auxiliary cleaning scraper 12 to move through the round end of the movable rod 16. A movable rod 16 is inserted into the fixed rod 10. One end of the movable rod 16 is fixed to the main cleaning scraper 11, and the other end of the movable rod 16 is a round end that moves through the movable cavity 501. The two push disks 701 move synchronously due to the rotation of the threaded rod 7. When they move synchronously, they can act on the two movable rods 16 at the same time, so that the movement of the movable rods 16 can drive the main cleaning scraper 11 and the auxiliary cleaning scraper 12 to move stably at the same time.

[0027] Please see Figure 2 and Figure 3In this embodiment, the fixed rod 10 is also provided with a movable groove 1001 inside. A return spring 18 is provided inside the movable groove 1001. The rod body of the movable rod 16 moves through the inside of the return spring 18. A movable block 17 is also fixed on a section of the movable rod 16 inside the movable groove 1001 and is slidably connected to the inner wall of the movable groove 1001. One side of the movable block 17 is fixed to one end of the return spring 18.

[0028] Specifically, the movable groove 1001 is used for the movement of the reset spring 18 and the movable block 17. When the movable rod 16 is pushed by the push plate 701, the movable block 17 pushes the reset spring 18 to compress. When the push plate 701 moves away from the movable rod 16, it is reset by the reset spring 18 and can drive the movable rod 16 back to the initial position. That is, it can drive the main cleaning scraper 11 and the auxiliary cleaning scraper 12 away from the inner wall of the emulsification tank body 1, thereby avoiding the main cleaning scraper 11 and the auxiliary cleaning scraper 12 from always sticking to the inner wall of the emulsification tank body 1.

[0029] Please see Figure 2 and Figure 5 In this embodiment, one side of the main cleaning scraper 11 is away from the inner wall of the emulsification tank body 1, and the bottom of the auxiliary cleaning scraper 12 is away from the inner bottom wall of the emulsification tank body 1. The distance between the main cleaning scraper 11 and the inner wall of the emulsification tank body 1 is greater than the distance between the auxiliary cleaning scraper 12 and the inner bottom wall of the emulsification tank body 1.

[0030] Specifically, since there is an angle difference between the main cleaning scraper 11 and the auxiliary cleaning scraper 12, the auxiliary cleaning scraper 12 is closer to the inner wall of the emulsification tank body 1 than the main cleaning scraper 11. When the main cleaning scraper 11 and the auxiliary cleaning scraper 12 move synchronously, it can be ensured that the main cleaning scraper 11 and the auxiliary cleaning scraper 12 are in contact with the inner wall of the emulsification tank body 1 at the same time.

[0031] Please see Figure 2 and Figure 5 In this embodiment, a positioning hole 502 for inserting the bottom of the threaded rod 7 is provided on the inner bottom wall of the movable cavity 501 near the bottom of the rotating rod 5, and a handle is fixed on the top of the threaded rod 7.

[0032] Specifically, the positioning hole 502 allows the bottom of the threaded rod 7 to be screwed in easily, stabilizing the bottom of the threaded rod 7, while the top of the threaded rod 7 has a handle for easy gripping by workers.

[0033] Please see Figure 1 and Figure 2 In this embodiment, a servo motor 3 is also installed on the top side of the fixed cover 2. A drive gear 4 is installed on the power output shaft of the servo motor 3, and a driven gear 6 is installed on the top of the rotating rod 5. The driven gear 6 meshes with the drive gear 4.

[0034] Specifically, after the servo motor 3 is started, it can drive the drive gear 4 to rotate using its power output shaft, thereby driving the driven gear 6 that meshes with it to rotate, and thus the rotation of the driven gear 6 can drive the rotating rod 5 to rotate.

[0035] Please see Figure 1 and Figure 2 In this embodiment, a circular positioning groove 14 is provided on the top of the emulsifying tank body 1. A sealing ring is fixed to the inner bottom wall of the positioning groove 14. A circular positioning block 15 is fixed to the bottom of the fixing cover 2. The fixing cover 2 is fastened to the top of the emulsifying tank body 1, and the positioning block 15 is placed in the positioning groove 14 to squeeze the sealing ring and is fixed together with bolts.

[0036] Specifically, when subsequent maintenance is required on the inner wall of the emulsifying tank body 1 and the stirring blade 13, the bolts can be unscrewed to facilitate the removal of the fixing cover 2 from the top of the emulsifying tank body 1. The fixing cover 2 can then carry the rotating rod 5 and the components on the rotating rod 5 out of the interior of the emulsifying tank body 1 for easy maintenance. The designed positioning groove 14 and positioning block 15 facilitate the positioning of the fixing cover 2 during subsequent installation and, together with the sealing ring in the positioning groove 14, achieve a seal between the two.

[0037] Please see Figure 1 and Figure 2 In this embodiment, the top of the fixed cover 2 is also provided with a feed pipe 8 and a vacuum pipe 9, and the bottom of the emulsifying tank body 1 is provided with a discharge pipe, which has a valve.

[0038] Specifically, the feed pipe 8 is connected to the feeding equipment, the vacuum pipe 9 is connected to the vacuum equipment, and there is a valve on the discharge pipe, which can be opened to discharge the material inside the emulsification tank body 1 when it is necessary to discharge the material.

[0039] In use, the external drug preparation enters the emulsification tank body 1 through the feed pipe 8. The emulsification tank body 1 is evacuated through the vacuum pipe 9. Then, the servo motor 3 is started. The power output shaft of the servo motor 3 drives the drive gear 4 to rotate, which in turn drives the driven gear 6 meshing with it to rotate. This drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the stirring blade 13 on the rotating rod 5 to stir the preparation inside the emulsification tank body 1 to achieve emulsification.

[0040] After emulsification is complete, the material can be discharged through the discharge pipe located at the bottom of the emulsification tank body 1. When it is necessary to clean the inner wall of the emulsification tank body 1, the operator only needs to turn the threaded rod 7, which causes the threaded rod 7 to drive the push plate 701 to move downward in the movable cavity 501. During the movement, the push plate 16 is pushed, and then the movement of the movable rod 16 is used to push the main cleaning scraper 11 closer to the inner wall of the emulsification tank body 1 and push the auxiliary cleaning scraper 12 closer to the inner bottom wall of the emulsification tank body 1. Thus, the main cleaning scraper 11 is in contact with the inner wall of the emulsification tank body 1, and the auxiliary cleaning scraper 12 is pushed closer to the inner bottom wall of the emulsification tank body 1. The scraper 12 adheres to the inner bottom wall of the emulsifying tank body 1. With the drive of the servo motor 3, the rotation of the rotating rod 5 can synchronously drive the main cleaning scraper 11 and the auxiliary cleaning scraper 12 to scrape and clean the inner wall of the emulsifying tank body 1. The contact point between the push plate 701 and the movable rod 16 can be adjusted by further loosening or tightening the threaded rod 7, thereby adjusting the movement distance of the movable rod 16. This allows for adjustment of the distance between the main cleaning scraper 11 and the auxiliary cleaning scraper 12 and the inner wall of the emulsifying tank body 1, thus achieving the purpose of cleaning materials of different viscosity.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
