Description

Technical Field

[0001] This application relates to the field of pharmaceutical preparation equipment technology, and in particular to a constant temperature stirring device for preparing analgesic ointment. Background Technology

[0002] In daily life, people actively participate in various physical exercises and sports to enhance their enjoyment of life and improve their physical fitness. However, if they do not warm up adequately before exercising or if the intensity of the activity is too high, their bodies are prone to bumps and knocks under external force, which can lead to acute soft tissue injuries. In such cases, a blood-activating and swelling-reducing powder is usually used for treatment. It has significant effects in promoting blood circulation, removing blood stasis, reducing swelling, and relieving pain. Currently, the most common form of blood-activating and swelling-reducing powder is a gel ointment. This ointment is based on vegetable or animal oil and combined with various medicinal components to form a gel-like substance. When using it, simply apply it to the injured area to effectively exert the drug's effects and relieve the patient's pain.

[0003] In the preparation of pain-relieving ointments, the constant temperature stirring equipment plays a crucial role. Because the raw materials of pain-relieving ointments contain vegetable oils, animal oils, and various medicinal ingredients, these substances are very easy to adhere to the inner wall of the stirring equipment during the stirring process. As the stirring time is extended, the adhered ointment will gradually accumulate and thicken, resulting in the waste of raw materials. At the same time, the ointment adhering to the equipment may deteriorate due to long-term storage, and be mixed into new ointment in subsequent production, leading to impurities and other problems in the product. Therefore, this needs to be improved. Utility Model Content

[0004] To address the issue of easy adhesion of ointments, this application provides a constant temperature stirring device for preparing pain-relieving ointments.

[0005] The constant temperature stirring device for preparing pain relief ointment provided in this application adopts the following technical solution: A constant-temperature stirring device for preparing analgesic ointment includes a stirring tank. A stirring mechanism is installed inside the stirring tank. The stirring mechanism includes a drive motor, a stirring spindle, and multiple wall-scraping assemblies. The stirring spindle is rotatably connected inside the stirring tank. The output end of the drive motor is connected to the end of the stirring spindle. All wall-scraping assemblies are arranged on the stirring spindle. Each wall-scraping assembly includes a stirring support rod and a fan-shaped scraper. The stirring support rod is vertically arranged on the stirring spindle, and the fan-shaped scraper is arranged at the front end of the stirring support rod. The outer edge contour of the fan-shaped scraper is adapted to the shape of the inner wall of the stirring tank.

[0006] Because the raw materials of the pain-relieving ointment contain vegetable oil, animal oil, and various medicinal ingredients, these substances are very easy to adhere to the inner wall of the mixing equipment during the mixing process. As the mixing time increases, the adhered ointment will gradually accumulate and thicken, resulting in waste of raw materials. At the same time, the ointment adhering to the equipment may deteriorate due to long-term storage, and be mixed into new ointment in subsequent production, leading to impurities in the product. By adopting the above technical solution, including a mixing tank, the mixing mechanism is installed in the mixing tank. The mixing mechanism includes a drive motor, a mixing main shaft, and multiple wall scraping components. The wall scraping components include a mixing support rod and a fan-shaped scraper. When stirring the ointment, open the feed port at the top of the mixing tank and pour the prepared raw materials into the mixing tank in sequence. According to the process requirements for ointment preparation, set the stirring parameters and heating temperature. After the mixing tank reaches the set preheating temperature, start the drive motor. The drive motor drives the stirring spindle to rotate, which in turn causes multiple scraping components installed on the stirring spindle to start working. The stirring support rod on it drives the fan-shaped scraper to make a circular motion. The outer edge contour of the fan-shaped scraper is adapted to the shape of the inner wall of the mixing tank, and the arc-shaped scraper blade at the top protrudes towards the tank wall, which can scrape off the raw materials adhering to the inner wall of the mixing tank and make them participate in the stirring process again, ensuring that the raw materials are fully mixed. When the set stirring time is reached, the drive motor automatically stops running, and the stirring process ends. Start the tilting motor. The tilting motor drives the transmission shaft connected to its output end to rotate. The mixing tank will slowly tilt under the drive of the tilting mechanism until it reaches the appropriate discharge angle. Open the discharge port at the bottom of the mixing tank and collect the prepared pain relief ointment into the pre-prepared container. After the material is discharged, the mixing equipment should be cleaned in time. A small amount of water is needed for a simple rinse. The mixing tank can be opened and the mixing mechanism can be easily removed to clean up any remaining traces of residue on the mixing mechanism, ensuring that the equipment is kept clean. With the addition of a stirring mechanism and a scraper assembly, the stirring support rod of the scraper assembly is vertically connected to the stirring main shaft. The outer edge of the fan-shaped scraper at its front end is precisely matched with the shape of the inner wall of the mixing tank. During the stirring process, it can closely adhere to the tank wall, effectively scraping off the raw materials adhering to the tank wall, avoiding the accumulation of raw material residue, and ensuring that the raw materials in all parts of the mixing tank can fully participate in the mixing. This makes the raw materials of the pain relief ointment more evenly mixed, improves the quality of ointment preparation, and at the same time reduces raw material waste and lowers production costs.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a constant-temperature stirring apparatus for preparing analgesic ointments. (Refer to...) Figure 1 The constant temperature stirring device for preparing pain relief ointment includes a stirring tank 1. In this embodiment, the stirring tank 1 is cylindrical with a hollow internal structure. A support frame 7 is installed below the stirring tank 1. The support frame 7 is made of multiple square steel welded together. A flipping mechanism 8 is installed on the support frame 7.

The flipping mechanism 8 facilitates the rapid discharge of the ointment in the mixing tank 1, reduces residue, improves discharge efficiency, and can easily flip the mixing tank 1 to a suitable angle during equipment cleaning and maintenance, making it convenient to thoroughly clean all corners inside the tank.

[0030] Reference Figure 1 and Figure 2The mixing tank 1 has a cavity 6 inside its wall. The cavity 6 is formed along the circumference of the mixing tank 1. A heating element 61 is installed in the cavity 6. The heating element 61 can be a heating component such as a resistance wire or a resistance strip. The structure of the cavity 6 provides installation space for the heating element 61, so that the heating element 61 can be evenly distributed around the mixing tank 1 to achieve uniform heating of the raw materials in the tank.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the mixing tank 1 includes a tank body and a tank cover. A stirring mechanism 2 is installed inside the mixing tank 1. The stirring mechanism 2 is detachably installed inside the mixing tank 1. The stirring mechanism 2 includes a drive motor 21, a stirring spindle 22, and multiple wall scraping components 23.

[0032] Reference Figure 1 and Figure 2 Multiple scraping components 23 are arranged on the stirring main shaft 22. The scraping components 23 are multi-layered and arranged alternately along the axial direction of the stirring main shaft 22. The multi-layered and staggered scraping components 23 can scrape the inner wall of the mixing tank 1 from different heights and angles in an all-round and thorough manner, ensuring that the raw materials adhering to various parts of the tank wall can be scraped off in a timely and effective manner and re-participated in the mixing. This further reduces the accumulation and residue of raw materials on the tank wall and ensures the uniformity of the mixing of raw materials in the mixing tank 1.

[0033] Reference Figure 2 and Figure 3 Each wall scraping assembly 23 includes a stirring support rod 231 and a fan-shaped scraper 232. The stirring support rod 231 is vertically arranged on the stirring main shaft 22 and can be detachably installed between the stirring support rod 231 and the stirring main shaft 22. The fan-shaped scraper 232 is arranged at the front end of the stirring support rod 231, and a connecting support plate 3 is installed between the stirring support rod 231 and the fan-shaped scraper 232.

[0034] Reference Figure 3 The stirring rod 231 has an installation slot 4 at its end.

In this embodiment, the fan-shaped scraper 232 can be made of hard rubber material to ensure its scraping effect while preventing scratching the inner wall of the mixing tank 1. The arc-shaped scraper blade 2321 further enhances the scraping effect. The arc-shaped scraper blade 2321 conforms to the shape of the tank wall curve and scrapes off the raw material adhering to the inner wall of the mixing tank 1, effectively avoiding the residue and accumulation of raw material on the tank wall.

[0036] The implementation principle of the constant temperature stirring device for preparing pain relief ointment in this application embodiment is as follows: When stirring the ointment, the feed port at the top of the stirring tank 1 is opened, and the prepared raw materials are poured into the stirring tank 1 in sequence. According to the process requirements for ointment preparation, the stirring parameters and heating temperature are set. After the stirring tank 1 reaches the set preheating temperature, the drive motor 21 is started. The drive motor 21 drives the stirring spindle 22 to rotate, thereby causing the multiple wall scraping components 23 installed on the stirring spindle 22 to start working. The stirring support rod 231 on it drives the fan-shaped scraper 232 to make a circular motion. The outer edge contour of the fan-shaped scraper 232 is consistent with the shape of the inner wall of the stirring tank 1. The material is compatible with the mixing tank 1, and the arc-shaped scraper 2321 at the top protrudes towards the tank wall, which can scrape off the material adhering to the inner wall of the mixing tank 1 and make it re-participate in the mixing process, ensuring that the material is fully mixed. When the set mixing time is reached, the drive motor 21 automatically stops running, the mixing process ends, the flip motor 81 is started, the flip motor 81 drives the transmission shaft 82 connected to its output end to rotate, and the mixing tank 1 will slowly flip under the drive of the flip mechanism 8 until it reaches the appropriate discharge angle. Then the discharge port at the bottom of the mixing tank 1 is opened, and the prepared pain relief ointment is collected into the pre-prepared container. After the material is discharged, the mixing equipment needs to be cleaned in time. A small amount of water is needed for a simple rinse. At the same time, the mixing tank 1 can be opened and the mixing mechanism 2 can be easily removed to clean up any remaining traces on the mixing mechanism 2, ensuring that the equipment is kept clean. With the addition of a stirring mechanism 2 and a wall scraping assembly 23, the stirring support rod 231 of the wall scraping assembly 23 is vertically connected to the stirring main shaft 22. The outer contour of the fan-shaped scraper 232 at its front end is precisely matched with the shape of the inner wall of the mixing tank 1. During the stirring process, it can closely adhere to the tank wall, effectively scrape off the raw materials adhering to the tank wall, avoid the accumulation of raw material residue, and ensure that the raw materials in the mixing tank 1 can fully participate in the mixing. This makes the raw materials of the pain relief ointment more uniformly mixed, improves the quality of ointment preparation, reduces raw material waste, and lowers production costs.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
