Description

Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical ointment production, and in particular relates to a stirring mechanism of an ointment homogenizing emulsifier. Background Technology

[0002] A homogenizing emulsifier is a specialized device for mixing, dispersing, and homogenizing various liquids and semi-solids. It uses a high-speed rotating agitator and emulsifying head to uniformly mix two immiscible liquids (such as oil and water) to form a stable emulsion system. This equipment is widely used in various industries such as food, cosmetics, and pharmaceuticals, especially in the production of products requiring fine processing and high stability. For example, in the production of various ointments in the pharmaceutical industry (such as erythromycin eye ointment), homogenizing emulsifiers are essential. An indispensable part of a homogenizing emulsifier is its unique stirring mechanism. A vacuum homogenizing emulsifier unit consists of a homogenizing pan (with a liftable lid and a tilting pan body), a water pan, an oil pan, a double-stirring system with scraping walls, a homogenizing emulsification vacuum system, an electric or steam heating temperature control system, and electrical controls. However, the related stirring mechanism still has the following drawbacks in actual use:

[0003] First, because homogenizers need to form an emulsion from two immiscible liquids, the emulsion is quite thick and will inevitably stick to the inner wall of the pot. Therefore, some agitators are equipped with a wall scraping structure to scrape off the sticky emulsion material. However, the position of these wall scraping structures is usually constant, which makes them unsuitable for use with homogenizers of different sizes.

[0004] Secondly, when stirring in the homogenizing pan, the scraping part and the stirring part usually rotate at the same speed. This results in either the scraping speed being too fast or the stirring speed being too slow, leading to poor scraping and stirring effects. Slow scraping and fast stirring are required.

[0005] Finally, most homogenizing pans have a curved spherical bottom, but the stirring structure does not touch the bottom during stirring. This results in material adhering to the bottom of the pan, which also needs to be scraped off. At this time, the scraping process needs to be adapted to the curved bottom structure of the pan. However, different containers have slightly different curvatures of the bottom, making it impossible to adapt. Utility Model Content

[0006] The purpose of this utility model is to provide a stirring mechanism for a paste homogenizing emulsifier. By setting up an upper cover, scraper, connecting rod, second support rod, turntable, rotating shaft, rotating blade, first support rod, and arc plate, it solves the problems that the scraper part cannot adapt to the use of homogenizing pans of different sizes during stirring. By setting up an upper cover, scraper, connecting rod, and second support rod, it solves the problems that the scraper part cannot adapt to the use of homogenizing pans of different sizes during stirring, the low processing efficiency caused by the synchronous speed of the scraper part and the stirring part, and the inability to adapt to the scraping of materials with different pan bottoms.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a stirring mechanism for a paste homogenizing emulsifier, comprising an upper cover, a turntable, a rotating shaft, a main shaft, and scrapers. The turntable is rotatably connected to the inner cavity of the upper cover, and the main shaft is fixedly connected through the center of the turntable. The rotating shaft is symmetrically rotatably connected inside the turntable outside the main shaft. Two sets of rotating blades are centrally symmetrically fixed on the area below the turntable on the rotating shaft.

[0009] Two vertically distributed support rods are fixed to the lower part of the main shaft located below the turntable, and a scraper is also provided below the turntable. Two vertically distributed connecting rods are fixed to the side of the scraper near the main shaft, and the two connecting rods are inserted into the support rods corresponding to their height.

[0010] A support rod is fixed on the outer circumferential surface of the bottom end of the main shaft. An arc plate with an arc-shaped bottom surface is provided below the support rod. A bolt is screwed through the support rod, and a rotating ball is fixed at the bottom end of the bolt. The lower middle part of the rotating ball is movably embedded in the upper end surface of the arc plate.

[0011] Furthermore, a main motor is fixed at the top center of the upper cover, and the output shaft of the main motor passes through the upper cover and is fixedly connected to the upper end of the main shaft.

[0012] Furthermore, an auxiliary motor is fixed to the upper end of the turntable, and a drive wheel is fixed to the output shaft of the auxiliary motor. The upper ends of the two rotating shafts are located above the turntable and are fixed with driven wheels. A belt is fitted between the drive wheel and the two driven wheels.

[0013] Furthermore, a ball bearing is rotatably connected to the outer circumferential surface of the turntable, and an annular groove is formed on the inner wall of the upper cover. The outer edge of the turntable and the ball bearing are both disposed within the annular groove.

[0014] Furthermore, a connecting plate is fixed to the outer periphery of the main shaft located below the turntable. The connecting plate is located above the rotating blade and the second support rod. The two rotating shafts are respectively rotatably connected to the two ends of the connecting plate. A vertical plate is also fixed to the upper end of the connecting plate. The upper end of the vertical plate is fixedly connected to the bottom surface of the turntable.

[0015] Furthermore, both the upper and lower ends of the second support rod are open, and the end of the second support rod away from the main shaft is also open. Two limiting strips are fixed on both inner walls of the inner cavity of the second support rod, and the connecting rod is inserted into the cavity formed between the four limiting strips.

[0016] Furthermore, a long rod is inserted between the two connecting rods, and the bottom end of the long rod has an end with an inner diameter larger than the gap between the limiting strips. The upper outer circumference of the long rod has a threaded section, and a nut is screwed onto the threaded section of the long rod above the second upper support rod.

[0017] This utility model has the following beneficial effects:

[0018] This invention solves the problem that the scraping part cannot adapt to different sizes of homogenizing pans during stirring by setting up a top cover, scraper, connecting rod, and support rod II. Before stirring, the scraper is moved according to the size of the homogenizing pan, so that the connecting rod is horizontally displaced within support rod II until the outer edge of the scraper contacts the inner wall of the homogenizing pan. At this point, the position of the scraper is determined. Then, a long rod passes through the two connecting rods, and the nut is rotated downward on the threaded section of the long rod until the bottom end of the long rod is locked with the nut on the limiting strip within the two support rods II, thereby limiting the position of the connecting rod. Thus, the scraping position of the scraper can be adjusted.

[0019] This invention solves the problem of low processing efficiency caused by the synchronous speed of the wall scraping and stirring parts by setting up an upper cover, turntable, rotating shaft, rotating blades, and scraper. The main motor on the upper cover drives the main shaft and turntable to rotate slowly. The slow rotation of the main shaft causes the scraper to rotate slowly as well. With the rotation of the turntable, the two rotating shafts move in a circular motion. At the same time, the auxiliary motor drives the two rotating shafts to rotate rapidly. Together with the high-speed rotation of the rotating blades, the material is stirred. This results in the scraper and the rotating shaft rotating at different speeds, which effectively increases the processing efficiency and achieves slow wall scraping and rapid stirring.

[0020] This utility model solves the problem of scraping materials that cannot be adapted to different pot bottoms by setting a support rod and an arc plate. Rotating the corresponding bolt inside the support rod allows the arc plate to rise and fall to a certain extent at different positions. With the design of the rotating ball, for example, rotating the two bolts on the right to lower the arc plate will cause the arc plate to rotate at a certain angle around the rotating ball at the bottom of the bolt on the left, thereby fitting the bottom surface of different homogenizing pots and facilitating material scraping.

[0034] 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.

[0035] Please see Figure 1-10 As shown, this utility model is a stirring mechanism for a paste homogenizing emulsifier, including an upper cover 1, a turntable 2, a rotating shaft 3, a main shaft 4 and a scraper 5. The turntable 2 is rotatably connected in the inner cavity of the upper cover 1. The main shaft 4 is fixedly connected through the center of the turntable 2. The rotating shaft 3 is symmetrically rotatably connected inside the turntable 2 outside the main shaft 4. Two sets of rotating blades 301 are fixedly fixed in a centrally symmetrical manner on the area of ​​the rotating shaft 3 located below the turntable 2.

[0036] The upper cover 1 is a lifting pot cover (the lifting part has been omitted). It has a rotating turntable 2 inside. The main shaft 4 is set at the center of the turntable 2. The main shaft 4 and the turntable 2 rotate synchronously. The rotating shaft 3 moves in a circle with the turntable 2 and rotates on its own axis. The rotation of the rotating shaft 3 drives the rotating blade 301 to rotate and stir, so as to stir the material in the homogenizing pot.

[0037] Two vertically distributed support rods 404 are fixed at the lower part of the main shaft 4 located below the turntable 2. A scraper 5 is also provided below the turntable 2. Two vertically distributed connecting rods 501 are fixed on the side of the scraper 5 near the main shaft 4. The two connecting rods 501 are inserted into the support rods 404 corresponding to their height.

[0038] The rotation of the main shaft 4 leads to the rotation of the second support rod 404, and the scraper 5 is inserted into the second support rod 404 through the connecting rod 501 and fixedly connected to it. Thus, the rotation of the main shaft 4 leads to the rotation of the scraper 5, which scrapes the inner wall of the homogenizing pot.

[0039] A support rod 401 is fixed on the outer circumferential surface at the bottom of the main shaft 4. An arc plate 402 with an arc-shaped bottom surface is provided below the support rod 401. A bolt 4011 is screwed through the support rod 401, and a rotating ball 4012 is fixed at the bottom end of the bolt 4011. The lower middle part of the rotating ball 4012 is movably embedded in the upper end surface of the arc plate 402.

[0040] Before rotating the corresponding bolt 4011 inside the support rod 401, the arc plate 402 is raised and lowered to a certain extent at different positions. With the design of the rotating ball 4012, for example, rotating the two bolts 4011 on the right side to lower it, the arc plate 402 will rotate at a certain angle with the rotating ball 4012 at the bottom of the bolt 4011 on the left side, so as to fit the bottom surface of different homogenizing pots. Then, by rotating the main shaft 4, the support rod 401 is rotated, so that the arc plate 402 scrapes the bottom of the homogenizing pot.

[0041] A main motor 101 is fixed at the top center of the upper cover 1, and the output shaft of the main motor 101 passes through the upper cover 1 and is fixedly connected to the upper end of the main shaft 4.

[0042] The main motor 101 on the top cover 1 is working, which can drive the main shaft 4 and the turntable 2 to rotate slowly.

[0043] A secondary motor 202 is fixed at the upper end of the turntable 2, and a drive wheel 2021 is fixed on the output shaft of the secondary motor 202. The upper ends of the two rotating shafts 3 are located above the turntable 2 and are fixed with driven wheels 302. A belt 2022 is fitted between the drive wheel 2021 and the two driven wheels 302.

[0044] The auxiliary motor 202 rotates with the turntable 2. At the same time, the operation of the auxiliary motor 202 drives the drive wheel 2021 to rotate. It works with two belts 2022 to connect two driven wheels 302, causing the two driven wheels 302 to rotate. After the driven wheels 302 rotate, the rotating shaft 3 can rotate.

[0045] A ball bearing 201 is rolled on the outer circumferential surface of the turntable 2, and an annular groove 102 is provided on the inner wall of the upper cover 1. The outer edge of the turntable 2 and the ball bearing 201 are both located in the annular groove 102.

[0046] The outer circumference of the turntable 2 is provided with ball bearings 201, and the outer edge of the turntable 2 is set to rotate within the annular groove 102. With the setting of the ball bearings 201, the friction is changed to rolling friction, making the rotation of the turntable 2 easier and reducing friction.

[0047] A connecting plate 403 is also fixed on the outer periphery of the main shaft 4 located below the turntable 2. The connecting plate 403 is located above the rotating blade 301 and the second support rod 404. The two rotating shafts 3 are respectively rotatably connected to the two ends of the connecting plate 403. A vertical plate 4031 is also fixed on the upper end of the connecting plate 403. The upper end of the vertical plate 4031 is fixedly connected to the bottom surface of the turntable 2.

[0048] A connecting plate 403 is also provided outside the main shaft 4. The main shaft 4 and the connecting plate 403 rotate synchronously. The connecting plate 403, together with the vertical plate 4031, connects to the turntable 2 to assist in the installation of the rotating shaft 3 and increase the stability of the rotating shaft 3 when it rotates.

[0049] Both the upper and lower ends of the second support rod 404 are open, and the end of the second support rod 404 away from the main shaft 4 is also open. Two limiting strips 4041 are fixed on both inner walls of the inner cavity of the second support rod 404. The connecting rod 501 is inserted into the cavity formed between the four limiting strips 4041.

[0050] When installing scraper 5, insert the connecting rod 501 on its side into the support rod 404 of the corresponding height. The four limiting strips 4041 located in the support rod 404 are restricted. Then move it to the appropriate position and stop.

[0051] A long rod 6 is inserted between the two connecting rods 501. The bottom end of the long rod 6 has an inner diameter larger than the gap between the limiting strips 4041. The upper outer circumference of the long rod 6 has a threaded section. A nut 601 is screwed onto the threaded section of the long rod 6 above the upper support rod 404.

[0052] After determining the position of the connecting rod 501, the long rod 6 is inserted upward through the connecting rod 501 from below, so that the end contacts the lowest limiting strip 4041. Then, the nut 601 is screwed onto the threaded section until the nut 601 contacts the uppermost limiting strip 4041. In this way, the long rod 6 and the nut 601 lock the connecting rod 501 and the limiting strip 4041, so that the connecting rod 501 cannot be moved.

[0053] The specific working principle of this utility model is as follows: First, select the homogenizing pot to be used and place the upper cover 1 above the homogenizing pot. Then, according to the size of the homogenizing pot, move the scraper 5 so that the connecting rod 501 is horizontally displaced within the support rod 404 until the outer edge of the scraper 5 contacts the inner wall of the homogenizing pot. At this time, the position of the scraper 5 is determined. Then, the long rod 6 passes through the two connecting rods 501 and the nut 601 is rotated downward on the threaded section of the long rod 6 until the bottom end of the long rod 6 is locked with the nut 601 on the limiting strip 4041 within the two support rods 404, thereby limiting the position of the connecting rod 501 and thus determining the scraping position of the scraper 5.

[0054] Subsequently, the corresponding bolt 4011 inside the rotating support rod 401 causes the arc plate 402 to rise and fall to a certain extent at different positions. In conjunction with the design of the rotating ball 4012, if the two bolts 4011 on the right are rotated to descend, the arc plate 402 will rotate at a certain angle with the rotating ball 4012 at the bottom of the bolt 4011 on the left, thereby fitting the bottom surfaces of different homogenizing pots.

[0055] Finally, the main motor 101 on the top cover 1 starts working, which drives the main shaft 4 and turntable 2 to rotate slowly. At this time, the scraper 5 scrapes the material adhering to the inner wall of the homogenizing pot. At the same time, the auxiliary motor 202 drives the drive wheel 2021 to rotate, which in turn connects the two driven wheels 302 with two belts 2022, causing the two driven wheels 302 to rotate. After the driven wheels 302 rotate, the rotating shaft 3 will rotate. The rotation of the rotating shaft 3 drives the rotating blade 301 to rotate and stir, thus stirring the material in the homogenizing pot and achieving the operation requirements of slow wall scraping and fast stirring.

[0056] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
